Hey guys! I am now a proud owner of a 1987 T2 RX7 with 100x miles.

Now I have a few questions about it!

When you turn it on, it has the common "cold start" problem, but then the idle surges, is that cuased by a vaccum leak?

Also, I am taking out the TB, should I go ahead and do the TB mod, will I notice a differnce at all?

Also, are there any writeups on ported a WasteGate? IF i remember correctly, once I get a FCD, RB Exhaust, and a Walbro 255lph pump, I would get boost creep. And porting the wastegate would solve that problem.

Also, what about an exhaust? I have herd mixed between BNR, Racingbeat, and CorkSport. Any recomendations?

 

Yes, Yes, and yes. It could also be your TPS, but check for vacuum leaks first.

Exhaust - search.
