sacreligious!!!! I don't care how fast it is. "twice the HP and twice the torque of a stock E30 M3 it will be a true CSL" csl is the lightweight model. I'm pretty sure the S14 weighs less than an LS1 [screwy]

Plus an s14 ALONE that still runs is worth more money on the market than what an LS1 and transmission would cost to buy brand new! So why's he asking $15k?! Shouldn't it be less, since it has cheaper (monetary) components in it? [screwy]

I've seen an E36 LS1 swap and a Gen III RX-7 LS1 swap.

The LS1 is actually very light, the result of the aluminum block versus the iron block of the S14. I couldn't find the actual #s in a brief search, but I think it will surprise you how close they are. Indeed, it is within the realm of possibility that the LS1 is lighter, as hard as that may be to believe.

It is still sacrilege.

The LS1 weighs 390 lbs and the S14 weights 340 lbs. 50 lbs isn't that great of a difference, especially given the gain in the power. I wouldn't call the car a CSL, though. The thing that bugs me about the ad is that he says it has a "new 2001 GM Corvette LS1/LS6." So which is it? An LS1 or an LS6?? There's a BIGdifference in the power between the two engines!

A new LS1 crate motor costs $6000 discount mail-order, not including the transmission. The T-56 6-speed transmission looks like it costs about $3000 new, also discount mailorder. I'm not convinced a running condition S14 engine would be worth more than $9000 given the amount of miles that these things have on them now, and the amount of work most of them need.

I wouldn't call it sacreligious. It's just different. This guy probably had an M3 with no engine/tranny and decided to do something interesting with it. I do think $15k seems a little steep, especially since the engine and tranny aren't new, but are out of 2001 cars.

I'd like to drive it, but I wouldn't buy it. Personally, I'd rather have the M3 with an S14 AND the 2001 Z28 that the engine and tranny came out of.

Alright but if you add a good tranny to that S14, it could EASILY be $9,000 depending on the condition.

Have you ever driven a 4 cylinder E30? They feel completely different from the 6 cylinder. An ls1 or an ls6 would throw off the balance of the car. Most likely there would be more weight over the front wheels than with the S14. It will feel completely different - if you ever get a chance to drive a 318is (E30) or ever have... you'll know what I mean. They are 100x more nimble than ANY 6 cylinder E30 I've driven.

BTW The sources I looked at said the LS6 weighs around 450 lbs w/out a tranny...so if he has an LS6 that would add a lot of weight.

Like I posted in another thread - who cares if it's faster?? Give me a chevy small block V8, transmission, and $5,000. I'll get a few friends together and build a small car out of steel tubes that does 0 - 60 in 2.5 seconds. Speed isn't everything. Especially on an E30 M3 which was built with handling in mind.

He should've done it to an E36 [hihi]

I disagree that the LS1 would significantly throw off the balance of car. If anything, the LS1 conversion might even handle better than an E30 with an M20 - the M20 weighs 440 lbs, and if the LS6 really weighs as much as you say it does, then an LS6 would probably be comparable to a six pot E30. It's doubtful that he has an LS6, though. If he did, would have made a big point out of it and wouldn't have even mentioned the LS1.

Irregardless, I wouldn't buy it for $15,000. If I wanted an E30 with an LS1, I'd buy a junkyard LS-1 and T-56 for about $3000 or so (the current going price) and throw it in my E30. Adding $1000 for miscellaneous stuff that would be needed to complete the conversion, I'd have a total vehicle investment of about $5500 if you include the original purchase price of my car. $15,000 is steep.

But he didn't say z06. In 2001 the LS6 didn't come in the base model corvette.
Yeah, I know. I'm just saying that it's possible it could have an LS6 since it came from a Corvette and not a Camaro. It would had to have been from a Z06 if it is an LS6. The seller is the one that said it has an LS1/LS6. But, it almost certainly has an LS1, because he would have made a big deal out of it if it had an LS6. His ad is somewhat misleading, because while the LS1 and LS6 basically look the same externally, they are very different engines.

the long and the short of it is that the tool that decided to put a small block Chevy motor into a Beamer should have his head examined. I wonder if i can buy the old engine and tranny from his E30 and put it in me Cavalier!!!!
