whatever you want. i vote 102 for the gains over the new runner design. but others will probably complain about the price, or the other stuff you have to buy, or modify to put in on your car blah blah blah. gotta pay to play

102 is the best but expensive and can be a hassle to install.

I vote 92mm. Going to have "similar" gains, better down low power for cheaper and better fitment...and it looks better is you are getting the new black one.

i dont know why everyone talks about fitment. mine fits just fine. Yea its closer to the cowl, but it bolts up the exact same. unless you are dead set on keeping your STB, i personally could care less about a strut brace.

Are different fuel rails needed for the 102 or will the stock ones work?

Undertow74

iTrader: (45)

no, stock will not work so you need the billet, or the oem style ls2 rails

Fitment can be a problem with Vettes. On an Fbody if you have a 102TB it may not clear the waterpump. It will not clear the water pump if its a EWP. Get a LS2 water pump and you are fine.

^^ exactly what i did, LS2 pump is like $120 with free shipping and includes gaskets. cheap insurance also since most of our cars are 10+ years old

102 is not too big. Thats utter nonsense. In long run the 102 is more money but worth more power. Period.

And you can make it black or any other color in an hour for less than $20.

I did the 92mm fast. Didnt have to worry about fuel rails and such so I saved money.
Did tea 243 heads, 228 cam, 92 fast, 3.73 and other small upgraded boltons. My stalled auto gained over 100rwh on mustang dyno. 429/392

I vote 102 with the 92mm tb to save some time getting the tune dialed in. The 102 tb can be a pain to tune for driveability. The cost of the 102 over the 92 is minimal when you can easily pick up 5 or more horse from 2k to The top.

Will ls2 rails work with the 98 fbody fuel system?

bww3588

Seems to be the million dollar question. Just searched that and I found 2 answers.

1. The 98 has the regulator on the rail and to switch to any other rail, you have to use the Corvette FPR/filter.

2. The regulator on the 98 rail is simply a dampner and all f bodies are regulated at the pump.

Just check your pressure at the line with it unhooked from the rail. If it's around 58psi, it's regulated at the tank.
