KA24DE rebuild for low boost
hey whats up all, i got a 96 SE and after thorough research on turboing the KA, ive decided thats what im gonna do. compression test today revealed that cylinder 4 is only squeezin about 125 psi out. i kno it should be around 175. anyways...now i need to get new pistons cuz my rings are done on that cylinder. I was wondering, do i NEED to get cams and valves, springs, retainers? or can I just get some new pistons since im only lookin for about 6-7 psi and 230 hp or so. Im pretty sure the stock forged rods will hold up under that. Also, most of the forged pistons i see are oversized so i would need a bore? is there anyway around this so i dont have to strip it down to the block?
Im thinkin wiseco pistons, better head gasket, new timing chain......stage 1 boostdesign kit. thanks yall

yo i just talked to a guy i know that has a turbo altima (KA24) and he said dont go cheap on the rods. also, are you sure they have stock bore pistons? im still gonna need to sned the block to a machine shop right, since the 9 yr. old pistons are so broken in to the cylinder...

hey keep me up to date
I am interested to hear how it goes. I'd like to see if I could get 200 to 300 HP out of the KA especially since it only has 53,000 miles on it. I am anxious to hear how your project goes even though I am sure it will be a long process.

Pull the head, oil pan, crank, rods and pistons. you have to hone by hand w/ drill but no pullin o' the block

yeah my compression is fine, about 180 or above across the board. i re-checked it a few weeks ago, it mustve been a faulty gauge whcih i suspected cuz the car runs fine. anyways, i got my 370 SR injectors and a JWT ecu on the way that i got for 400 bucks. now just waitin for sum $ for the kit
also just installed a turbo-back exhaust on my firneds wrx...wow that thing is nice
