??? For you OFI owners I’m ready to buy something now and I have read most every thread about OFI and I’ll leave it at that.
Keep in mind I’m a noob to FI
. I have a forged 347, all bolt on’s, suspension, etc. and do a best of 10.7 at 125 so far N/A. I will have about 9.1:1 CR and an undetermined cam at this point (open to suggestion on that one too). My goal is simple, I want low 9’s in a 3400 pound car.
What turbo choice would be the “best” for me, mix of street and track (mostly track)? How would the S76 or S78 in a T-6 work with my setup, how about the ST76 or ST78 in a T-4 flange?, or should I just stick with the 76GTS? I really don’t know what will even fit on the kit, so I can use some help there.
I don’t have power steering or ABS anymore so those two things won’t be in the way. Any other fitment issues besides the plug wires?
Feel free to give your over all opinion on the “kit” itself and the install. All info is much appreciated before I make the plunge.

for low nines in a 3400lb car a T76gts will be a little harder to get there with that turbo.
you could do it with a t4 flanged PTE88 or either a t4 or T6 flanged S78 or larger.
with a 346 you can stick with a t4 flange, no biggie, if you get bigger like in the 36X range a t6 flange would work better for you.

I don't have plans to do it soon, but I will eventually go 402 CI or bigger, would it be Ok to do a T-6 on the 347", or just upgrade to the t-6 later on?
Hopefully some of the other OFI folks will pop in here and drop their .02

The fact that you have read all the threads about OFI and your still wanting to buy from them means you have more faith than I do!! Ive heard that people give them $$ and they cant get in touch with them anymore!

I bought a set of headers from Joel a while back. Had to wait for them, but you'll have to wait anywhere you buy a front mount set up. I'm pretty pleased with the quality and fit, although there is a tube too close to the coil pack on the driver's side. Luckily I've got a set of truck coils I can use, which move the coil and plug wire away. I should be testing the limits soon.

Try to look up what Kyle did with his S turbos.
I don't remember the specifics anymore but I believe he went from an S76 or GT-42 76 to an S88 and he saw retarded improvements and might have hit low 9s...or at least the car hit low 9s

.Another question for you all, would air to air or air to water be better?
