OK, so after reading (and saving) for six months I buy an 86' TSi. It's red, perfect interior, 75,000 miles, but it turns out... we needed to replace the clutch, front u-joints, and suspension components all around. No problem compression test is spot on for all 4 cylinders the turbo is in great shape no noise from the valve train or timing components, it appears someone previously did a really nice job welding the exhaust manifold back together but it actually looks pretty solid. Now I've got $2000 and a month to start in on the G54B before I put her on the road. Here's the thing I want to produce some power gains but without compromising any durability. Now anybody who's spent five minutes in this forum alone knows there's alot of ways to go about it. I plan on putting more cash in later in the spring. For now though I want to bulletproof this thing as best I can. In the end I want to produce about 260hp@5500 and 390lb/ft@2500.
Stock 12a with wastegate, bpv, and braided oil and coolant lines at 8-1-psi? / Or is the 12a not worth working with?
I think I should replace the head right off the bat, whats the best casting for my money? Should I bother to pay for porting now? Are HD springs worth it if I don't do the valves, guides, or cam?
I'd also like to do a full catless 2.5" turbo back exhaust, as the car isn't required to meet emissions here but it's a lot of cash. Is it worth it to do just the manifold, down pipe, and b pipe to eliminate the cats?
If I don't expect too much in the way of power gains right away should I do more than just an 86' FCD and rising rate regulator to the FI system? Or is that useless without other work? And if so should I do an injector and pump upgrade, or an AIC system, or go full on MPI?
Anyways long post I know, thanks for reading this far. I'll take any input I can get. What would you do first, with $2,000 and a month?
