Though I still feel upgrading the injectors is a good idea as well. There is a reason the S15 had 440 injectors. Of course if you do that I also suggest a different MAF and a good tunable ecu or a ECU Flash.

More fuel more air flow more power and higher boost capability. Of course everything has it limits internally as well.

You want to play you have to pay.

That first quote should have been what's it take to go 13-15lbs on a T28...

That seems like a cheap swap.

So injectors, maf...with the stock ecu handle that or is that tuning time?

I am planning on adding to this as I go, I just want to get some power under the hood as that's the only thing left.

It sounds like just a stock SR20DET with sidemount even would be fun to start.
