Hey Everyone! I'm (obviously) new to this forum, but not to forums in general. I just picked up an 88 GT, took it for a ride and parked it for the winter. Now I'm starting to build on what I have:
So over the last couple of weeks I have been doing alot of reading, and have planned a few mods. This is what I have to work with:
BBK cat delete h-pipe exhaust
BBK Cold air
Mac shorties
3.73 rear
70mm EGR (Not Installed)
So my thoughts are to start from the top and work my way down, going with a 70mm TB/EGR spacer, upgrade injectors (Bosch D3's or similar) Then an electric fan, smog bypass belt (83.5" I believe) and synthetic fluid all around.
I am keeping my A/C until it dies (still working strong) And would like to have about a $1000 budget. I also will get some subframe connectors and shock tower bracing to handle some flex. So my first question is with the 70mm EGR, how much grinding do I do to make it flow into the intake without compromising the gasket seal? Looks like there are only a few mil's contact to the stock upper manifold?
Thanks in advance, any and all suggestions welcomed!!
