Attn:All Ka-T Sohc/Dohc need set up ideas

[SxMachine]

Whats your Ka setup SOHC or DOHC, and have u reached your power goals. Seems like everyone who turbocharges their single cam stops with their starter kit, usually a 7-10psi, 200-215 whp setup (not that those are bad results by any means).

Im looking into my own turbo setup. I believe the reason why people stop there is because at that point they do not have to rebuild their bottom end, above that point (~7psi) the ka bottomend will fall apart. I dont know from experience, but constant searching. there is information everywhere. read it all!

anyway, I am going to assemble my own turbo.

z31 T3 I believe, smic, fmu

good luck!

It will hold more than 7 psi...but it must be in excellent condition and tuned right. Dennis at Unstable Hybrids has been pushing 350hp, 15psi for quite some time without problems on a stock block. I know another person making over 300 reliably as well. The SOHC is limited a bit by it's head (more restrictive than the DE) but is still capable of high power.

[ftrs13]

but did he upgrade the pistons or rods?? anything like that? 15psi is pretty good. of course for someone who hasnt done a turbo before, me and I am assuming the poster as well, there should be some room for tuning error. I agree thought that a properly tuned engine without any detonation could hold more boost.

I know that i just want to be a little on the safe side

if tuned properly a KA should handle 10psi no problem if the engine is in decent condition. when i turbo my KA i plan on pushing it to 10 psi every once in a while (daily driven prolly round 7 psi) and i dont plan on a rebuild for awhile

It is 100% stock with a JWT ecu re-tune (I'm getting one too with that kind of reliability!)
