I have a Gt2871r ( ohsnap! ) I'm going through some fuel intercooler and tune issuses now.
you can get a 3'' intercooler and plumbing from ( CXracing.com ) you will save tons of $$$$$$. just you have to get it welded.

Keep the stock fuel pump in and get a inline pump because when the factory pump is replaced with a aftermarket pump you will get fuel cut a little bit at 1/2 tank of gas. Fuel cut at 1/4 you will get fuel cut then at next to E a lot of fuel cut. The pick up is no good the stock is better. Leave it alone. get the in-line and a fuel pressure gauge to read ( psi ) of fuel. That way if your in boost on the dyno you can tell if there is a loss of pressure to the injectors.

I have VF enginnering mounts the engine doesn't move!

The dog bone mount for the tranny is a must!

Lower control arms...... get the high dens hockey puck bushings, i went full urethane I have to replace the VF mount work to well so something had to give.

Question if you start making good power..... look at getting a first and second gear selecter the rivit is going to break that's if you have the ( O2M ) tranny.

Please build the bottom end.....your wallet will thank you for it.
