S54 vs LS1 Swap for my E30...???

Then the black flag owns you

Just don't give a point by. When you see them waving wildly in your rearview, it's because they like you. Just hit the loud pedal on the straight and watch them recede in your mirrors.

Not likely. :D

very likely, Ive seen it happn too many times when I go out or just record for friends on the stands

Body work pics coming this week and I will take pics of parts as they arrive. :D

[Bimmerfreak87]

For sure. I'm gonna order the go pro hd camera soon so I will take picks and video.

I know power isn't the only factor to good lap times. I plan on running race suspension, coilovers, nice race tires, etc. My friend has a ls6 zo6 w/ cam, lt's, afr heads, cf int, and ext, but everything else is stock including tires, suspension, and weight. He may get tires before we race though. We will just have to see what happens. I still gotta build my e30 though. :D Just started collecting parts...

All I ask, is take LOTS of pictures. Good luck!

Spec Miatas run within a couple of seconds per lap to close to stock Z06's from what I can see on CorvetteForums and spec miata times. Spec miatas top out at ~120 whp for the better motors at ~2400 lbs, depending on the specific car. If beating your friend is what you want, get tires, suspension, and lots of track time. I'm just saying, other than drag racing, power isn't the most necessary thing to get good lap times. Plus, how satisfying would it be to crush his dreams in a low-powered car that cost little more than his wheels and tires. :p

But, YMMV.

That's at the wheel btw in a 2200lb E30.

LS1, no fucking question. Here is the dyno for a buddy of mine's E30 race car.........very lightly modded LS1.

Cam (reasonably mild)
LS6 Intake
Headwork (cnc ported)
Ported stock TB
Custom Headers

So there is a TON of fucking power left on the table. Flip side is, I bet this motor will easily last him a few seasons. Brings the CG closer to the center of the car while being lighter than an S54 (IIRC) and doesn't come with the "BMW" tax on parts.

Infineon Raceway/Sears Point, Laguna Seca/Mazda Raceway, Thunderhill, and Sacramento Raceway (Drag Strip) will be the main tracks we run. GRM Challenge sounds cool... might think about that for next year. My ridiculous E30 build is going to be fun and totally over the top. :)

What track will you be going to with you friend? Good suspension and good tires go a really long way on racetrack times. If you get a lot of seat time, building a car like THIS is the way to do it. A stock LSx will give you plenty more power than you need. Ryan could lap TWS, a track with 2 big straights, great for a high-powered car, in 1:55. Most instructors in C6 Z06's run ~1:57, on race tires and suspension. If you really want a fast, cheap car with a V8, follow This Vorshlag E30 build for the GRM Challenge.

I don't think it'll take a crazy engine swap to catch up and pass your friend in the Z06 on a track day.

Then again, I always like seeing a ridiculous E30 build that goes way over the top.

There ain't no substitute for cubic inches! More hp (340) and more torque (340lbft)! Another couple hundred for a new cam, and 50 more hp! throw in "a little" more money, supercharge the LS1 for another 125hp! See:

So stop worrying, and get some big power1

[Bimmerfreak87]

guaranteed you'll be passed by 160hp miatas and hatches at the track , horsepower is only a part of the equation.

Not likely. :D
