First off, the car:



It's a 2000 2.5RS automatic with 99,000 miles on the clock. I just had the head gaskets (one was leaking) and water pump replaced. The timing belt was done 3,000 miles ago by the previous owner. The car is in great shape, no rust, etc. My original plan was to do a 2.0L USDM WRX swap with an 06-07 tranny. It was going to be a mostly stock build but a lot of fun. And then tonight it hit me: I've got a perfectly good motor and transmission right now. It's not my only car (the RX-7 pictured is my other car) so if I have motor issues, my logic is great -- I'll buy a swap and do it. 5LBs of boost, 200WHP... lots of fun. But in the mean time, here's the plan:

TD04 60-1 Turbo
STi TMIC
WRX turbo manifold
2.5" DIY turbo back exhaust
WRX injectors
Undecided on engine management
Some upgraded torque converter for the auto

What are your thoughts on this? Like I said, if it goes boom I don't really care. The motor/tranny combination itself isn't really worth too much so I don't have much to loose. Any input on the best way to manage fuel? Please keep in mind this will be my daily driver. I think this could be a cool little project.

5 psi on stock injectors is fine with an RRFPR; you won't need the WRX injectors. If you want real engine management, go with a PP6 or a Emanage Ultimate. The latter is the better but more expensive option. Also, you will need an upgraded fuel pump.

Also, if you're going to use a WRX manifold/up-pipe, you must either notch the crossmember, or install a turbo crossmember so the up-pipe clears it. Or you can make a custom up-pipe using the stock manifold.

I don't really know what good the upgraded torque converter on the tranny would do. at 5 psi, you're not looking at enough power to requre upgrading the driveline.

I agree with everything you've said. I'm not going to touch the transmission and I'm going to go with a Walbro 255 and build a custom up pipe. And I'll stay on stock injectors. I think I will go with some form of engine management since I'll need it anyway when I do my "real" swap.

Just did a quick road tune last night and I am running stock pump and injectors/FPR.

So I'm hitting 5 psi steady right now and added fuel and the injectors are close to maxing out.

If I went to 6-7 psi then I would really need to up the injectors. I will do that in the winter with some 300+ or 440 injectors and the wrx pump I have.

I am using Emanage Ult and is perfect for this setup and a lot more. If you do have the coin then get a nice stand alone..might as well!

Just get a better clutch right now.
