I have a 99 I30 and was wondering what i can do for the best performance. I really don't have the money for a turbo or supercharger at the moment, but everyone says get the y-pipe. My question is, if i were to put bigger injectors in it what else would i have to change or mod? the ecu? also what would the injector size be 370cc? Thanks

If you dont have SC or turbo, bigger injectors wont give you anythink.
Like most people says. Get ypipe!!

Y-pipe, MEVI, JWT or TC or G-force ECU... those are the biggest ones I can think of

TC ? You mean TS, technosquare and there is no g-force anymore.
And he has a 99 so he's SOL on the ECU's for now ...

i thought you could send them a 96 core and they could mod it to work with the 99. that was in a previous thread that i have read about the ECU's for 99's and stuff.

do the y-pipe, do exhaust, see how you like that first.

You could get an intake, 00VI, underpulley, lighten flywheel, ect.

Why don't you call JWT and ask them then ? And theres also the "98-99 ecu thead sticky"

There are people trying to work on it (a 99 ECU). The problem is that outside the major ECU vendors, people with resources are few and far between. So it seems that a grassroots, basement type operation is in order...

who cares about a CEL unless its for something that actually matters? I'll take a 95-96 upgraded ecu with a cel if it performs without any problem. and the dude who tried the 96 in his 99 didnt have any luck with it
