I'd just pick up some 550's. always nice to have a bit of room to expand dude.. but sounds like youre holding off a bit anyhow.

Yeah, I really need to just be responsible and pay off some debt. Hell, it's not like I haven't spent over $3k on the Supra in the last 3 months anyways.

you can always swap it with another good set until $$$ is available. hell, my twins smoke a bit and still boost like crazy. I plan to go single this summer.

The turbo's aren't smoking that bad. And I don't want to deal with the hassle of swapping the twins, especially since it's an 8+ hour job.

jgdynamics, I'm not exactly sure which kit I was looking at, you will have to call Robert at 935 and ask since I believe he said he only has 2 of the kits in stock.

So I've been gone for a few months, and people already forgot that you CAN run more then 18psi on stock twins? Jeez guys, come on. We put that old wives tale to bed 2 years ago.

Reaper, that was at stock fuel pressure. The OP already stated that he has an AFPR, more pressure, more fuel.

not necessarily. I could run my 800cc injectors almost wide open on my stock pump, making 400whp. No matter what the pressure, the pump simply could not flow enough fuel.
