yeah i need to know what would be the best turbo to use on a 8.7:1 compression engine? i know cvcc heads aid in detonation on D16A1 engines. but i need to know what turbo would be good with this head setup, and not have much creep and no spiking.
btw this is for a honda engine.
and i need to know where to get Turboedit. so i can stop engine ping and running 91+ octane.

Compression is the only factor you pretty much don't consider when picking a turbo. Compression might come into consideration when you are deciding max boost but compression overall does't mean crap in this situation. All heads aid in detonation, without them you wouldn't have any compression, duh. T78 would have no creep or spiking, in fact you'd never even spool it and thus you'd be safe from detonation. I think that is probably your best bet. If I were you I'd put a thunderbird supercharger on just to mix things up a bit.

i asked a simple question, i didnt ask for a lecture mr. assistant. i basically need to know what turbo WONT make the d16 explode, even though the block is basically bulletproof.

Why are you being a dick? By having chris tell you that on the forum, youve now prevented yourself from looking like an ignorant dipshit when you go spouting off something in person. And if you actually bothered to read his post, he said the T78.

psssssh read man.
"in fact you'd never even spool it and thus you'd be safe from detonation."

i think by wanting a turbo, THAT ID WANT IT TO SPOOL.

psssssh read man.

He means that it will have minimum if any turbo lag. Lag you don't necessarily want, which causes possible denotation or engine knock, as Chris stated above.

Denotation you don't want.

yeah but coming from him it sounds like he's basically saying that the car wouldnt have enough power to even get the turbo to spool up.

yeah but coming from him it sounds like he's basically saying that the car wouldnt have enough power to even get the turbo to spool up.

He's saying the turbo would be efficient enough so you wouldn't have to spool it. The bigger the turbo, the longer it will take to spool. If it's the right size, you'll never have to spool it.

You said you didn't want detonation. Well a huge turbo your car is pretty much incapable of spooling is your only option to completely avoid detonation. If you understood the very BASIC concepts surrounding your question you wouldnt have asked it in the form you did. I told you there are way more factors involved than compression. A cool enough intake charge and sufficient fuel is all you need to avoid detonation.

j x k e: its just the fact that i know what ive been told. and i ask a question. and its like you guys come up with some stupid bullshit.

If you already knew the answer, why ask?

j x k e: ive posted everything youve said to people from g2ic, and do you know what they call you? "TYPICAL MAZDA JACKASS"

Then don't ask me for my opinion.



I have no problem helping out someone who wants to learn and admits that they don't know something. I'm not saying I know everything by any means and when I don't know I research it and find out or I say "I don't know". I don't make up some lame lie that doesn't even reach the outer-most edge of logic.

to prove how much you really know h4r.

you picked a turbo for your prelude and thunderbird and a supercharger for your escort out of a junkyard, how can you not pick one for a civic?

I don't think anyone here needs you to prove how much I know.

omg lmao....


" blah blah blah blah *insert honda engine code* blah blah blah... oh yeah its a honda engine !! "

because i want something for a little more power, not all out racing power like the prelude was. and i ordered that turbo from preludepower, so that was like the best turbo that THEY said to use on the a20a1. so im trying to gather up opinions on what turbo would best suit me for 200whp, so the block doesnt explode like most peoples integras do. if you look on preludepower.com you'll find a list of turbo'd preludes, and theres like 23 failures, and 29 passed with flying colors after driving for a year at a minimum of 6 psi. but the other 23 failures ran the same 6 psi and blew up. im just trying to find a turbo that wont blow the motor, and still put out enough power to get it up to 200whp. i know all the things i have to buy, i plainly cannot stress any farther that i just need a turbo opinion. not a lecture on engines and whatnot, ive heard enough from everyone else in the world on what to do to the engine and all that stuff. im trying to get like 3 or more opinions to come to the same agreement on turbo, i need something that'll spool, but not spike out, i need it to be reliable when i punch on the gas. so just tell me what would be the best turbo that WILL SPOOL, and not blow the motor. conquests have thier own special turbo setup that gets them to the high horsepower mark, without blowing a hole through a piston or burning up a valve. so do rx7's even tho they're apex rotary. cmon be logical, give me a real answer instead of some jackass comment about a turbo that wont even spool because i dont have enough power to push that.

get yourself a copy of Corky Bells "Maximum Boost" and you will have your answer.

even though the block is basically bulletproof.
can we test that out? i mean, if its bullet proof that is...

w/out a turbo, you can't get to 200bhp?

Your question is crap. Everyone has a different opinion. You can't just say "what is the best turbo?" As far as those cars blowing up, I can assure you it was due to crappy fuel or spark management not the kind of turbo on the damn thing. Even if the internals were too weak to handle the boost the block didn't EXPLODE from the turbo, it most likely threw a rod through the block. I can't say I've ever seen a block explode from having the wrong turbo... They generally just make crappy power when they're sized wrong.

conquests have thier own special turbo setup that gets them to the high horsepower mark

whats this special setup ? the turbo mounted directly to the manifold ? as apose to... on the manifold ?

The conquest has a very very basic twin scroll 12a water cooled tiny ass turbo. They make all of 170 hp stock. bah. high HP mark huh...

conquests are complete shit. From their worthless TBi fuel setup, to the shitty truck motor with balance shafts and jet vavles in it... they are trash from the ground up.


...without blowing a hole through a piston or burning up a valve.


I beg to differ. A very very small turbo, can burn a hole in a piston. I did it.

It comes down to alot more then the turbo.. is there enough fuel ? injector duty cycle.. fuel pumps.. CFMs the turbo is able to push at a given PSi.. ect ect.


take for example again the conquest... stock 12a turbo run 16 pounds on it, and its fast enough to beat modded fox bodys and break the transmission... i did it.

trash the 12a in favor of a 14b or a 16g wheel ina 14a/c housing and run the same 16 psi as before... wow... its a shit load faster !!!! wonder the hell WHY... cus that bigger turbo is pushing in a higher volume of air per psi... which in turbo needs more fuel, and it dosnt have and it eveuntly breaks... again... i did it.

my point is, you can take ur shit z16abcdickwad motor and put a small turbo and boost the hell out of it and make instant throtle responce power. use a bigger turbo, run lower psi, make better more usable power, run a HUGE turbo, deal with lag but make insane on boost power. Its all a matter of where you want your power and what kind of power. to answer your question as to what turbo u need, i would say one that builds boost would be a good start for you. theres only ten bazillions diffrent turbos you could run. look at what works, and what breaks, ad my advice would be use what works.

with that said...


Know what I really think? I think you just wish u could do a turbo set up, but cant, because funds wont allow, or your just plain stupid. I havnt figured it out yet... but insted of just dreaming about ur junk yard turbo set up and keeping it to your self, you ask stupid questions like this in hopes of auctauly making some one beleive you know what your talking about and are auctauly doing a turbo setup, when in reality your doing a SC setup right ?? on a factory turbo car... taking the turbo off, and doing SC.... that way u can take your S/Ced TII rx7 out to westgate and floor the hell out of it up and down blackstock...


one last thing...

whats the diffrence in " flooring the hell out of it" and just pushing th gas to the floor..... is it faster if u floor the hell out of it? gas pedel go down further ?

disclaimer : please ingore any and all typing errors. its late, the laptop keyboard sucks, and jetski isnt worth a proof read tongiht. thank you.

on a side note, Osborne has a junk yard turbo.... from a semi that is... however before undertaking his project, he wasnt on here asking BS questions... Insted he just took a micrometer and a dial indicator with him to the junk yard......

you think im kidding...


thats the diffrence in a ricer and a racer

that's crap, I took a calculator too

I drive an FD now but I'm STILL the JUNK YARD RACER!

no actually stegall, if you go pick up the local Iwanna classified paper, you'll see a 86 crx si for sale in it, infact its the one that says $800 beside it, and im picking it up from tigerville most likely either today or friday. and the only good engine swap is the d16 (browntop) dohc 88 integra engine, because why you ask?.the fuel injection and the harness works with the electronic dizzy on the d16 because its an si crx. now, heres where the turbo comes in, i want more power than 110 stock horsepower. but for some reason the most ever ran on a d16 was 200 WHEEL hp. which give some more and thats like 230-250bhp. because its the usual honda drivetrain power loss. on the other hand, thanks for the more HUMANE answer on the turbo that gives more boost
and like i said, im lookin for turbo opinions for a honda not a ford. if you dont believe me, you're welcome to come down, after i pick the crx up, and give me your all out opinion on what i should do.

as for the conquest. you're right on the mitsu 16g, since some members of starquestclub.com run this setup ="Mitsubishi Super 16g turbo, ported exhaust manifold, Walboro fuel pump, Bosch BCFPR, 1st Generation Eclipse MAS, MSD coil, 8.5mm Mopar Performance Plug Wires, 2.5 HKS Exhaust, and racing downpipe." and crank out some decent power, but of course they break, its a crappy montero/raider engine, they couldve done better on that car, my stepdads conquest suffered from what i call "BHG" quite often.
ive seen semi turbos, infact the guy lee bought his mk3 from, works on semi's, he had a old volvo semi turbo sitting in his garage, and let me tell you, its almost as big as me. and cosborne pulled one of these from a junkyard? for his car?
wasnt it, like, too humungous to fit on that car, even tho rx7's have enough room to dump a 5.0 in it with no problems.
and as far as going to the limit with micrometers and dial indicators, and all that crap, i have no knowledge of how to use these. sorry but some people just arent as mechanically inept as others.

but on the other hand, as to your suggestion, basically dont go too small, dont go insanely big, find a medium. thats more of an answer i was going for.
and chevymuscle, its not a chevrolet, its a honda. cmon. you spend 1k on a chevy motor, you got some major power, you spend 1k on a honda, and its still under 300 hp.
see im cheaping out on the swap, and going the easy route, the 88 integra engine, just wasnt made to handle that, now if i had say, 4 grand laying around, id drop in the b18 sitting down at lee's, but i dont have the money for that, i have to buy mounts, ecu, wiring harness, vacuum box, tranny, shifter kit, rebuild the motor to handle that kinda boost, even tho its a perfect platform to use for turbo, unless i just went cheap and bought a 90-93 integra LS, with a blown motor, but then id have to deal with all of the crap of cutting and welding, and im not a fan of that.
when i can save 600 bucks, call nippon motors, get a jdm engine sent here with a tranny, and call it a day.
trust me if i had the money, id just buy this

sorry to be so long on the reply, but i think i covered it.
and a statement from redpepperracing about d15's that are in the crx si.
"You could probably make as much power on it as you would with the d16a1. Most "d series" are rated at 200whp before explosion, with the IHI, you woudlnt make 200whp anyways, 160-180 max with the d15a3 i would think (depending on shape and kms),But I really woudlnt run 15-20 psi of boost on a little civic/crx with a d16a1. 10-12 psi is more than enough. With 10 psi, you shoudl be able to make 200whp with a decent turbo no problem (good luck finding one). this woudl be enough to put you into the 12s. anythign faster than that in a sub 2000 pound car is a recipe for disaster. " i hope that helps to aid you from saying i dont know anything. i know some stuff, but not as much as others.
go buy a honda and then tell me what you can do with it.
trust me, theres not much you CAN do. i just happen to like how they drive and feel.

I only read the part relating to me because I am busy and I'd just like to know how you could fit a 5' tall turbo in a volvo. Also, Volvo never made a turbo for a semi. Volvo, like most other companies outsourced their turbos. I also feel that you should look up what "inept" means.

like i said, VOLVO TURBO, which means it came out of a volvo SEMI. not made by volvo. it being almost 4 feet tall, is including the housing and everything, not just the turbo.
and give me a break its, 3 am. im not mister grammar, even stegall had his typos. why cant i have my misused words.

I did it because I felt like taking every part of your argument apart including your technical inaccuracies in an effort to completely extinguish what little credibility you have left here. Now back to your five foot volvo turbo in your "friend's" garage...

he's not a friend lol, hes a 35 year old man, that sold lee the supra, he lives off 176, hell i'll be even glad to let you follow me to his house to see this monsterous beast. its what he does for a living, hell he even gave us blue silicone hoses from a semi, to TRY to use for a busted radiator hose, that didnt work out so well.

4 foot turbo? lmao

btw...you wanna know what magical turbo to use? do as sean951 suggested an read maximum boost by corkey bell....it has everything you could ever want to know...and even things you didnt' know you wanted to know in it. also... www.howstuffworks.com go there, read, profit.

there's a reason i didnt' go through w/ my junkyard setup, and just bought a factory F/I car. most people don't knwo what they're doing and end up blowing stuff up. i've seen people turbo their engine and not touch fuel or spark.

if i were you, i'd look as something like a t25, tdo4L, ihi vf36, or a t28.

reply to jetski about: most ever ran on a d16 was 200 WHEEL hp. which give some more and thats like 230-250bhp. because its the usual honda drivetrain power loss. on the other hand, thanks for the more HUMANE answer on the turbo that gives more boost:

There is a 450whp D16 on Honda-Tech for sale. Im not even going to look for it because its a waste of time just ask some ppl out at westgate if you bring the thunderbird out this weekend.

I wish my engine would blow.

So now you're buying a crx instead of a prelude or did you forget about the prelude?

after i talked to him about it, he emailed me later and said he had a guy coming to look at it, and that the guy buying it would be back sunday and he would let me know if the deal fell out.
if i dont get it, i know who will. so i dont feel too bad about losing a deal like that.

Yeah, I'm sure you can find another in a junk yard.

i could, but not in that condition, and along with a 55k rebuilt engine to drop in it, for 400 bucks. running that cars worth well over 1500 bucks.

US dollars,or pesos ?

US. lol

I guess GT28R

that's a large compressor side turbo...w/ the "mad skyllz" that jxke has...he will for sure blow it up.

nice sarcastic comment there dickshit.

You obviously have no interest in technical support.
