Here's the steps you need to take.

1) Go find a shady friend.
2) Scope out and steal an Integra GS-R (make sure it's real)
3) Swap the B18c into your Teg
4) With the money you saved by being a little b!tch and stealing the engine, do some suspension work.
Walla!

Or you can do what the remaining 70% of the Import World does and just commit insurance fraud and use that money to get what you want done.

/me shakes his head.
I guess those are the two things I hate about the "import lyfe"
lol.
