10.6:1 cr and turbo????
any pros and cons on runing a T3 with .63a/r compressor on a hatch with a gsr engine? 10.6:1 JE pistons, stock rods and crank, stage 3 clutch, 255lbs H-P pump, and will get bigger injectors, fuel rail, ragulator, ignition system before the install. let me know please, im kinda new at boosting

Re: 10.6:1 cr and turbo???? (GS-Rcivic)
a buddy of mine had turbo on a stock GSR setup in his hatch and blew it up 2 times. I wouldnt trust running that high of compression w/ boost. that compression would work nice with nitrous though. good luck. (swap out the pistons for some lower compression ones and a set of eagle rods. happy boosting)

The compresion is fine...thats what jdm gsr motors come with. You can run 10 pounds all day long with proper fuel. I like it too cause its a daily driver and since the comp is good, it wont be a slug when your not boosting.

jdm gsr, thats what im in the process of boosting right now. As long as theres enough fuel, youll be fine. TUNING, TUNING, TUNING!

A friend of mine (GSRev) used stock B16A2 internals with his Speed Pro setup and made 332 to the wheels. That was at 12 pounds of boost.

Re: 10.6:1 cr and turbo???? (trustsi)
Yeah, the guy that blew up his GSR 2 times was running a stock GSR in his hatch, he had a skunk2 intake manifold, exhaust and a fpr.. hehe. and no tuning... I can't wait to boost my B20... Its 8.8:1 compression and its NO slug off the line at all.. I'm sure its in the 13's NA like it is. Imagine a decent 5-8psi of boost to go with it.

If you want to do it right for your fuel setup, depending on how much hp you want to make, get bigger injectors, fuel rail, and a standalone EMS.
good luck man. Your compresssion is more than ok for a turbo setup. Infact, you will make more hp pound for pound, and you will spool up faster because of your higher compression. Make sure you do your research and have a good tuner to tune that ems though.

im thinking of using the stock ECU, maybe send it out and get it tuned somewhere.

Re: 10.6:1 cr and turbo???? (itr206)
Just got done tuning itr206's car today, stock 10.6:1 compression. Car feels very responsive off boost, and for 6psi it pulls hard. Its all about tuning. I used to run a built b16a 11:1 compression engine, but sold it to a local kid.

Re: 10.6:1 cr and turbo???? (boosted hybrid)
correct me if I'm wrong but you make more power with high compression+ boost then low + boost. With good tuning on both setups a 10:1 at 5 pounds and a 9:1 at 5 pounds - same turbo and engine etc. The 10:1 will make more power and it will take quite a few more pounds of boost to make up for it on the 9:1.
There was an explanation somewhere too bad I can't find it. Anyone have the link?

an EMS is an engine management system (hondata, aem ems, etc.). If you want reliability and really want to know what your car is doing, then you need a standalone ems.

Hondata is good, and everything, but if running that much boost on higher than normal compression you might want the added control a true standalone offers you. Just my $.02.

No standalone and high compression+boost dont belong in the same sentence. You will blow your engine very quickly with no engine management and high compression.

Um, ok.
I was stating that the stock compression is higher than what most people preach is good for turbo. I don't believe in dropping compression when good tuning would be better, but there's more to it than just slapping on a decently sized turbo for the application in higher compression. After all there's turbo'd Type-R's here as well as other's that chose to run higher compression.
I personally run higher than that, but I don't suggest it for anyone. I play with timing more than fueling anyday, and I believe that's the key factor. The timing is the hardest part with higher compression. I still have problem with getting the EGT's to stay stable. I think I figured it out though. So basically I have more down time trying to get it all to work right, but when I get it up and running it should be fine. We'll see when it's all together.
