newbie with some questions
Hey guys im new to the group. I just purchased a 1992 sc300 with a TT 1.5jz that was built using a 2jz-ge bottom. Everything work on it expect it needs an ecu reflash or remap. Any ideas on what to do with this? Also it is the 4sp auto and i am considering swapping it for the 5sp man. Any help or info on both these issues would be awesome

These arent hondas bud. Why do you think it needs a tune? What it really needs is a different turbo setup as they are way out of their efficiency range on a 3.0
I understand you don't have the money for it, but it is what it is.. If you really feel the need for a tune cheapest bet is an safc.

is it not running right? I am guessing its on the 1jz harness and ecu setup. safc sounds easiest but maybe little larger injectors also depending on whats wrong. start with a wideband and seeing if there is a problem actually and make sure the 1jz ecu has a working o2 sensor.

I thought Vrank would know this one, I want to say I have read somewhere that going to a 2jzge block you should go one step larger injector size like from the stock 370's to 440's of an aristo or something like that but I have no idea if that is myth or good advice.
I would start with the wideband and see how its acting right now.
If you start adding in a bunch of fuel with a safc, you will hit boost cut faster and lower your timing, so if you have to add fuel everywhere step up the injector size first, and when you only need to trim certain areas you have the right injectors and then for small changes use the safc.
