It seems about right if you enter flywheel horsepower instead of whp

 

It looks like you'd have to be a great driver to pull off those times. It says that with my low boost horsepower (gonna be around the 400WHP) mark that I'll hit a 11.009 and high boost 500WHP it would be 10.2. I think it's probably geared for RWD, but if I got close to those times I'd be pretty F'n happy. It looks like the trap speeds are off though. I put in my friends specs which are about 2500lbs and 379whp and it says he should run the 1/4 in 10.9 at 124 mph, but his real time was 11.1 @ 130.

 

LS1 drop!! Ive seen a Miata at my track with an LS1 drop, didn't get to see what he ran though.

 

For the drivetrain question, the only thing that needs to be upgraded is the clutch. i can smoke the stock clutch even with only 105rwhp, lol.

As for the Ls1 drop.... That is what I really want to do. I think I can pull it off myself with the help from some friends and the local LSx tuner near here. Weight distribution is my only concern with a 5.7.

 

Drop a TT V6 in there?

 

I thought about that 2, 99. Finding the right combo has been difficult, and I've only seen one other guy (youtube vid) that did a V6. He had to fabricate everything to get it in there. An inline turbo 6 has entered my mind on several occasions.

 

Damn. What do people say about the handling characteristics on the V8 swapped cars? Would the frame have to be strengthened so it doesn't twist or are those cars pretty stiff as they are?

 

they have kits out there for a 302 swap, 3.8s use the same/smililar mounts so a single turbo 3.8 could work. 430 HP in a 2200 lb car = win

 

BIG BLOCK!! haha jk, i would turbo for the mean time but later, screw the LS1 you need the almighty LS9

2200lbs + 635hp= ........good god! you better roll race haha

 

guy i know did a ls1 into a miata, ran super rich and was untuned, he hit a 12.7 at 117, the car definitely had more in it
