I am considering dropping a 2j in my SC and taking out my 1j.
I have a jdm 2j in mind, I wanted to know what is the more power you can get from the twins ..... safely?
And what would it take?

a member has put out right around 500rwhp (stu?) on his 2j-gte engine but it takes A LOT. most likely you're looking low 400s i would say.

With easy bolt on stuff (not modifying the turbos, no external wastegates or morting the manifold, etc.), and 93, you can get upwards of 450WHP.

I don't know if you can "safely" push the JDM ceramic wheel turbos much over 16psi and expect them to last. So I would draw the line at under 400whp for the JDM turbo setup.

93 octane and 450RWHP may be a little optimistic. Possible, but not likely. But very possible to do some engine damage with that much boost (to make 450whp on stock twins, you're looking at 20lbs+) and 93oct.

IMHO, the key factors to making good power on stock twins (in regards to USDM TT), is a healthy motor, and healthy stock TT system (on boost leaks, etc) + high boost, and sufficient octane so that the ECU does not pull any timing.

Here's a good thread in the dyno section:

Thanks... It's somewhat what I was thinking..... I'll just put the single on from the get-go and be done with it.
