Ready To Do Upgrades To Rb 20 Det

[335]

Hello

I read the post about how people modded their RB20's but I want to know, what mods can be done with out having to buy a new computer and what upgrades require new computer.

I have stock everything except for the muffler exhaust, I think its a 3", it has a big opening and its made by Apexi. My airfilter is the green HKS kind.

Help please want to start now.

Thanks

there's no magical number or point where the stock ecu will not 'work.' it's more of a guidance

if you put an aftermarket computer on your car now and get it tuned, there will be an improvement.

most people will just get exhaust, intake (sounds like you have both of these, is it turbo back exhaust?), intercooler and up the boost. stock ecu should be fine.

but if you put on an aftermarket computer on at that stage, you will get even more of an improvement.

the trend usually is;

stock turbo = stock ecu

aftermarket turbo (big power) = aftermarket ecu

my advice = get an intercooler and crank the boost to 12ish psi. see how your coil packs hold out, see how your bank is going. want more power? get fuel pump, ecu, clutch and a bigger turbo
