hey i was just wondering if anyone has boosted with 11:1 compression, i know what some people are going to say which is ARE YOU CRAZY? but the awnser is no because i know someone that has LS/VTEC with 10:5 and was doing boost and still is... so if anyone has any info let me know

 

tuned right, anything can be done.

 

should be able to do low boost safely. i wouldnt go too high tho(6-7psi) as youd be raising the cylinder presure a lil too much. itd be good for a few horse forsure.

 

what kit do some people recomend for low boost and should i get a thicker head gasket to lower it a little

 

i heard a t67 turbo would make power with low boost...

 

get a turbo suited for your goals so u can have a decent powerband, and push as much psi as needed to reach it.

 

well i cant go to high because i will blow the motor up...i need a turbo that can make good power in low boost ...

 

I did 11psi on an 11:1 B16B with a GT28RS. made 300whp 200wtq. Never had a problem for a year than I went bigger and built the motor.

 

well believe me bro this just gave me a good sign of relieve,, i was about to lose intrest...tell me more about your setup...

 

All it was was a stock B16B with thin head gasket which bumped it up to 11:1 compression. I ran Neptune and had it tuned by Synapse motorsport. He just ran conservative timing and a little more fuel than normal.

Setup:
B16B
Thin Cometic Head Gasket
ARP headstuds
CTR cams
GT28RS
680cc Inj
Stock Map sensor
11psi
300whp
200wtq

If ther's anything else you want, let me know

ok well that look s good ill tell you my setup which is basically what they call a poormans type r,

block is gsr with 11:1 forged pistons E.N.D.Y.N and eagle rods ... stock headgasket....

the head is b16a with skunk2 stage2 cams, aftermarket retainer and valvesprings, and skumk2 manifold and skun2 68mm TB

i think that im going to just change the headgasket, my boy has a nice thick hks headgasket and that will lower my compression a little bit... also i have hondata s200 ....right now i dont know which turbo to get someone had said to me that the t3/t67 turbo but i dont know maybe ill check the one you used...how much did you get it for...or how much is it around too...

 

How much power are you looking for? The GT28RS is only good for about 325whp. I'm running a GT3076 with .63 hotside now and I'm making 502whp 365wtq with 9:1 compression.

With you having forged internals I would say you are a lot safer than I was when i had 11:1 comp. It all depends on your power goals though. If I were you I would get the turbo that I have now or a 57 trim.

 

s2000 have 11:1 comp factory. there is dozens of people daily driveing theirs boosted. gt3076R on 9 pounds will make just shy of 400 wheel, on a f20 anyway.

 

My 1.8L on 9lbs is probably 340-350 area.

 

well right now i just want some power, i would like to hit 300 whp with GT28RS which is what you did..(not sure yet) this is on 11:1 with low boost just to be safe... i plan on getting anoter block and doing low compression pistons

 

well if i get the turbo you have now am i risking it more or do you think it will be ok...i just dont want to boost if im going to blow it

 

run e85 it loves high comp with boost

 

I think you are better off with the GT3076 because it will make more power with less boost. Especially if you are going to go low compression in the future you will have a turbo that will make over 500whp with no problem. I did 502 on stock sleeves with only CP pistons and Eagle rods

 

did you order your kit or do part by part and just order the turbo...

part by part is way cheaper. Especially if you have a buddy that used to make manifolds for a turbo company

 

id say go with the gt3076r just like bootlegcivic said.. boost is addicting...haha

i do on the other hand have a fairly new garrett gt28rs...for sale...

i made 330whp with a completly stock gsr 92octane...
spool is crazy fast! hit full boost before 4k!! lmk if your intrested

 

You can definitely turbo it, but your goals are going to be limited by the fuel grade available. Theoretically you can boost an engine with crazy static compression IF the proper fuel is available (and economical) for use. Honestly, i would skip the GT30r because you're not going to use it to its potential on a higher comp stock block. I would stick to either a 57 trim or the GT3255e. Either of those turbos will make more power than your engine can handle while not breaking the bank. The difference between the GT30r and either of the 2 above is that the GT30r is suited more for higher pressure ratios and delivers better transient response. IMO, for the minimal gains, its not worth the extra $5-600.

an s372 will make great power at low boost.

but why would you do that?

get a turbo that will make the power you want, where you want it.

just remember as compression goes up, your window for tuning errors closes alot.

Lol...S372 on 4psi

I agree with Mike though, you should get a properly sized turbo that fits your needs, goals and budget. Anything else is a waste of money.

 

60 trim

This is what it is doing for me!
