S62 redline is rated at 7000. LS1s have a factory cutoff of 6200, but people spin them to 7200 with no problems with a quick ecu flash.

A lot of people get surprised when I let them know that I shift at 7k rpm, most people think that the ls1 redline is 5k rpm...haha. of course, if I had the stock cam I would be shifting at 6k rpm.

On stock lifters, psi 1511 mls springs, and ls6 cam. The s62 exhaust note is quite nice though.

Ah. The big thing I was wondering was springs. I'll probably run beehives when I build mine.

On stock valvetrain? Ballsy. 7900rpm redline iirc in the S62. I also meant how it revs, the exhaust note is amazing.

How high can you safely shift a stock s62? an LS3 can be shifted at 7k rpm safely, I shift my ls1 at 7k at least once month (with ls6 cam).

This is all true. But with the LS3 vs S62, the performance is marginal enough that id rather have the power band and revs of the S62. But if it were my dollar, I'd have the LS3, because an S62 swap is hella more expensive.

I have a 3.46 gear.

I also have racelogic traction control on my side as well.

[bmk]

In all honestly I don't have traction issues at all from 3rd-6th gear with 235 ss595's 3.46 gears. 430/485 and well over 600 ftlbs on the bottle. My e30 is a vert so it is a bit more heavy.

With higher gearing which Im assuming your gonna be running 3.73-4.10 and a lighter car I could see you having traction issues.

S62>ls3/5/7

Would agree, except LS7. LS7 is a monster. 650whp NA with basic bolt ons? 350tq at 1500rpm stock. I'm sorry, I love the S62 but to say it's a better engine than an LS7 is asinine.


Fwiw, future LS1/T56 (LS1 block with LS6 heads) swap here once the shop is built.

Ohh, the motor is not coming out. I get the hate and I was just saying I don't know if I could have done this to a blank canvas, but looking forward to putting 100k miles on this pig.

I live in Wisconsin. Its been in the negatives lately so the work that has been getting done is on the M62 E30 so I can free up some garage space. The M3 is getting completely torn apart, bare bones running, and built back up the right way. I'll update this with pictures as it progresses.

Fenders are rolled all the way around and I do have evo fenders. I will look there, but the consensus when I was looking seemed to be that 235s were the max. I still have not dug into this car.

235's right there on e34 system's

[DER E30]

It's what I'm doing. I have a thread up here of me doing the swap.

I'm guilty of possession of an LS also, its not in my e30 though... but the thought has crossed my mind once or twice

Enough thread jacking about LS, no LS, blah blah. OP has an LS installed in the car.

Lets get some new pics of the beast OP! :up:

[Reyhan335]

The LS might get hate, but it is probably the most economical swap as far as hp/$$ and reliability/$$ is concerned
