Ok all my parts r from ebay.. Everything but, my engine, which has good compression in every cylinder, but has alot of miles on it. My goal is to build a fun daily driver(ka24det). I dont want to boost alot maybe 8psi.. or 10..I using a t3/t4 turbo what brand idk! LOL! but its brand new i have a top mount header all my pipin bov oil lines and everything installed including a manual boost controller.. I have injectors i'm bout to install out the q45.. and a 255 walbro fuel pump.... I want advise on which way to tune it... I dont want to spend alot, but i will if i have to.. I just want a good tune that can help my engine hold up to 8 to 10psi...

I blew one engine already, but thats cause i was being a dumb *** ridin around with no tune on about 10psi on a stock engine with a stock fuel system.. yes i know that is

eBay huh? dont use their turbos so i've heard. you dont have to tune for boost, but you need a tune for the injectors fuel pump and maf. a tune is like $500. i'd watch out for a manual boost controller since you have no idea as to how much psi you turn it up to.

as for your already one engine down... i hope you learned if you feel the need for boost to tool around build you car and dont just jump the boost up

Yea My external waste gate is supposed to be set so i wont exceed 8psi, but im not going to trust that... so about $500 for a tune for my fuel pump and injectors ? I'm using a stock Maf right now. I had a z32 Maf, but I sold it man do I regret that.. I thought about buying a ecu that is tunned for 370cc injectors for the ka24det, but I see a lot of write up's for them sayin. Dont use them..Would a piggy back help me.. and if i did get one. Im going to need a wide band huh..? and some other stuff?

Another quick question... My buddy had bought some sr injectors 370cc's..We tried installing them in the ka24de and they looked as if they were too long. then one of my other buddies told me that i would have to drill in my fuel rail to make them fit.. NO! I didnt try it I want t ask around first because he has lead me wrong a couple of times..I just found a q45 in the junk yard with all the injectors in it.... If i pull them injectors will they be a direct drop in in my ka24de or will they look as if they r to long like the sr injectors did?
