i am in the proses of buying all me stuff to turbo my ka. i have about every thing i need. i bought the apexi afcII, in the manual it doesn't have the 240sx in ther it just has s14 silvias. does anyone know if the ecu wires are the same? when i turbo my car i have all the fuel management figured out i just want to know what other internal work i should do to my motor to insure there is no .......... problems. i am only shooting for 7psi daily and 10 at the max for now. can i get away with just piston rings and a couple gaskets? head, intake and exhaust gaskets?

 

do a comression test 1st, then think about turboing it . 7psi is cake stock blocks take around 350 hp daily but depens on how well ur motor is and for wiring the safc i belive is the 3n-b diagram do a search ull find it

 

ok thanks alot man

 

If you need any help with the SAFC, ill walk you through it step by step..... i did mine in like 30min or less..... really easy, i've got the ECU diagram if you need help hooking up the SAFC wires to the ECU.

 

do you know the rings are bad? if not why are you pulling the motor apart for just piston rings at least do a hone/bearing/ ect

 

well i dont know there bad yet i am going to run a comprision test on my motor in the next week or so.

 

Yes... definately compression test first.. remember, even if you rreplace rings , there will always be the "next weakest link" in the chain.

with good compression numbers .... 160+ , and all relatively close together.... you can support 7psi very nicely on a stock ka.

also, consider an msd ignition and a blaster coil, gives you a nice clean, accurate spark...

might I ask how many miles are on the motor right now?

 

there is no point of just replacing rings if ur not gonna hone or bore the block u might just have a egg shaped cylinder wich will cause also low compression. 7psi is cake stock motor handles 400hp with good tuning some dude reached 500+ on a stock motor with some ugly *** getho setup

 

aight well that sounds pretty good then thanks for helping. oh and i got like 130k miles on it, mostly highway
