Turbo CTR?

does anyone know, or care, if i can run a turbo setup on my b16a with CTR pistons? would the compression be way too high?

Well if you know what you are doing and have fast knowledge of how to tune a turbo setup, you could theoretically run a pretty high compression. I know that Sport Compact Car mag. ran a Toyota Matrix turbo at 11:1 compression and ran some pretty high boost. You might want to check out their site and look at their "Project Matrix" and see how they delt with the high compression. I think the key would be a really good valvetrain and some beefy connecting rods and REALLY good tuning of the boost control.

Don't do it. CTR pistons yield to high of compressoin for safe boost on a stock block. Your cylinder pressures would be too high also. If you want to run boost, use some lower compression or stock compression pistons. Also, a copper headgasket or something stronger than stock would be suggested. If you have CTR pistons already, squeeze a 50 shot wet on it and be happy with that. The fact that you have chosen CTR pistons should be to have more power daily, reliably from higher compression. Best of luck and "squeeze the fun out of it!" (remember squeeze-its?)

You'd need to upgrade your rods obviously, and good fuel managment will be the deciding factor in whether or not you blow up. :)

if i remember correctly, sport compact car blew that matrix up. they said something about it make lots of noise and then only running on 3 cylinders

Dude, I remember squeeze-it's those were sweet!!

Anyway, I agree, CTR + Boost is a bit too risky unless you really know what you're doing.

it would probably be a better idea if you were to strictly run 118 octane race fuel, but thats stuff's like $20 gallon :eek:

ok so maybe ill keep the ctr's and stick to my all motor plans.

if i ran a 50shot would i have to upgrade anything else. this is my setup as of now.

B16A
Crower Stainless Steel Valves
Crower Titanium Retainers
BPM Dual Valve Springs
CTR Cams
CTR Pistons

Yeh i agree. It'd be safe to run high cr turbo if you got all that shit upgraded. It puts more power to the ground than lower compression. You CAN'T boost as high as lower compression but you'll be just as fast or quicker than someone boosting high. Its all about tuning man. Thats one thing thats very important. Get it tuned right away if i was you. If i was gonna go boost i would go high compression!:)

No not really. If you go 60 or higher u need to upgrade ur fuel pump and rail. Its still not a bad idea to do that now.

hmmm...sorry melt, only if you run a dry setup. A wet kit has it's own fuel solenoid which will supply fuel with the nitrous. A dry kit uses your cars computer to read lean/rich conditions and add subtract fuel. In that case you will need to upgrade the fuel pump and also have your injectors cleaned, checked, upgraded for safety. In my opinion it is plain stupid to run dry kit unless you have upgraded fuel pump and injectors and have a way to tune them such as an AFC.
A 50 shot on the CTR pistoned B16 should be plenty safe but don't be stupid with it. Good luck.

umm i'm guessing he would've gone with a wet set up. and i'm not melt;)

damn, your not are you? Ha, my bad.
Sure, it is always suggested to upgrade the fuel pump when making upgrades and especially when introducing a power adder. But, for anything under 100hp of nitrous introduction, the factory fuel pump will be fine if it is indeed working in perfect order. I would suggest checking the injectors and at least have them professionally cleaned (none of this add to the gas B.S.). But with a wet setup the nozzle induces fuel as well as nitrous to equate for the more oxygen the nitrous offers.
Yep, I'm right. I know.:frog:
