Got a B18C1 jdm gsr motor i put eagle h beam rods in it along with some arias 12.5:1 piston. can i run a turbo w.o race gas. been told not to but i want some other opinions. if not....

i have a garrett 50 trim turbo a/r.50 5 bolt. legit garrett turbo not a ebay chepo ill be trying to sell along with a down pipe and a manifold offer a price im probly going to sell the stuff either wa so pleae let me knw. also have stock gr pistons and rods and injectors. offer a price!

 

your compression ratio is too high with those pistons to run turbo

 

yea that what i figured but i fig i would ask around too. do u know where i can post the turbo at like a clasified ad? on here tho not cl or ebay

 

im tunned on crome too do you like it?

 

Why would you install such high compression pistons then think about adding a turbo? And if you have a B18C1 it's a USDM GS-R motor, not a JDM motor.

 

post the ad on hondatech marketplace under forced induction for sale.

 

ok thanks. didnt plan on doing a turbo set up when i did the pistons and it was a quriosity question PaulMc and my bad on motor.

thank you lordhelmet

 

but u can throw a hundred shot in that bad boy.

 

Dont listen to these n00bs. You can turbo high compression all day long, all it means is that you are going to need lower boost to make the same amount of power on a similar setup. If you get the car professionally dyno tuned with a wide band and good enginge management you should be able to make so decent numbers. A low compression high boost setup is going to put just as much stress on your motor as a high compression low boost setup.

 

Sounds possible but not practical; still, I believe you do not fully understand the mechanics behind boosting. There is a reason why cars are recommended to run a low compression setup when boosting. I agree with the others had said. His setup is too high of a compression to boost.

 

This is the second questionable post I've seen from you, new 8 post member. While I acknowledge that one's post count doesn't necessarily reflect one's knowledge, it may benefit you to not disregard others as "n00bs" considering your position. Are you being an internet engineer?

With that said, yes, you can run low boost with somewhat high compression provided you have an exceptional ECU tune. Exceptional not just at WOT, but all throughout the RPM band. But 12.5:1 is NA territory. So what, are you going to run 4 psi boost? Why would you do that to yourself? High CR is for all motor madness. That's the only reason you go high CR (and I hope you're not running pump gas). Unless you're burning methane, high CR + boost usually = blown up engine.

 

ive got my car tunes on pump gas yes. and i have the understand of a turbo and everything the whole noob sign gives the wrong empression of me personaly and i can do turbo with that comp on race gas.

 

kchung is talking about the spiky hair dude, not you green_eg. The point here is that you've already got an engine for which running 91 octane is questionable. Adding a turbo would pretty much require race gas and for what kind of gain? You could maybe eke slightly more power out of an NA motor with a low psi turbo, but it's a challenging setup that would require special fuel and would make far less power than a conventional, reliable low compression turbo setup on pump gas. There's a reason we run high compression on all motor builds and low compression on turbo builds -- it's just the best way to make power for each build.
