I know this is a really old post but I wanted to get some more feed back on how the 4g15 ran with all upgrades with and without 4g37 ecu. I have all the parts but really just want to do the tb. Mainly bc my injector still work, my maf still works and ecu has a reman sticker on it so I assume its been replaced but never removed it. Then maybe ill get my old 4g15 tb bored to a 55mm tb sometime..
Im pretty sure ill put all the stuff on eventually and I am not really concerned with rev limiter even. Just want to see what you all think from your experiance.
Should I mess with timing (mod my cam gear or find adjustable) if I run the 4g15 ecu with all mods.
Im not trying to kill this old engine just give it some improvements and try to get it by until I get enough for a swap or replacement engine.
