hi there guys!!! do you guys think a 8.5:1 c/r on a b16a2 will be too low for daily driving with a greddy turbo only looking to boost 10-12 psi? please give me some opinions on what you guys think

 

yes...

I think on the B16A since displacement is small a CR of 9.5:1 and above is ideal actually but if you have low low compression then TURN up the boost. Youwill be able to run more boost with lower compression safely with less chance of detonation and/or poor tuning or less onservative tuning. I hope that made sense, YAAAWN!

 

yeah, like they stated in another post, if i got a head gasket to bump up the c/r a little then would that be alright?

 

WAY TO LOW!!! look at my post 12psi i made 231hp and 170tq off hondata thermal 3inch bla bla bla i say go with 9.8:1 and get her tuned

The difference between your 8.8:1 and 9.8:1 is, at best, 10-15 HP. Not that much in the grand scheme of things, and IMHO, it all evens out for being able to make however much more horsepower on the street.

 

D'oh, didn't read he's only planning on 10-12 PSI. for 10-12 PSI if you have a good tuner i'd go with 10:1.

 

yah but thats what i said and they all say yea i just want 10psi then is 12psi then is lets try 15psi then build the motor 18psi... like me i went from 5.5 to 6 then 7, then 9 then 11 and now 12psi and thats cuz i max out the stock map

i dont think so theres a hug difference... theres cars with the same setup making almost 300hp and 210tq of 12psi with 9.8:1-10.0:1cr

 

go as close to 10:1 as possible. im at 8.8:1 in my b16. see my sig

 

whats the stock compression ratio on a jdm b16a? i just got the car and learning about it. its got a greddy turbo kit for a gsr with a gsr comp. has a vafc and vortech fmu and i have no clue on how to tune the damm thing its sputting big time when i floor it or as the rpm climbs anyone? help!

 

9.8-10:1 seems to be the way to go

just make sure your timing and fuel is in check

There's more to the power difference than just compression. Sorry, but 1 full point of additional compression is not going to add 70 WHP to the car.

 

jdm b16 cr is 10:4:1

 

thanks drvfast!
