How really fast is a S52 or M50 E30...

[JGood]

I really don't understand why you are so confused about this:

335i
Curb weight: 3571
HP: 300
Power/weight ratio: 11.90

332is (my car)
Curb weight: 2720
HP: 266
Power/weight ratio: 10.25

Peak power is rather irrelevant in drag racing, unless you have a CVT. Your power/weight ratio may be better at a certain RPM, but is that the case the whole way through your usable power band? It may be, I'm not doubting you. Just saying peak power isn't the whole story.

An example, my friends 475whp Integra Type R only makes 475whp at 8000 rpm's or so. At 7000, it's probably only 425. At 6000 it's probably only 350. A muscle car that makes 425whp flat from 3k to 6k, even if a bit heavier, would probably beat it. And if they both started at 3k rpm's or so, it would be a joke. The integra has a much better peak power to weight ratio, but it doesn't show the whole story.

The thing is, the teg driver would have to be retarded to drop down as low as 3k.

Running through the gears he probably never drops below 6k, and at higher speeds in a longer gear you spend a lot of time near redline.

Power under the curve is all important, but in a street pull you're really only going to see the top end.

OK, my point wasn't exact. I'm just saying, you can't just look at peak numbers. You'll still see a 3k RPM range that power can vary in. When you're talking about motors that are within 30hp or so of each other, that is important.

Gotcha. Point taken :D

Not bad.

Would it be cheaper if you swap a M52? Fuck i am such a newb, i wish i have the skills to do work on my own cars lol :(

The cheapest and most powerful would be an S50 swap because it doesn't require any OBD1 conversion. You might be able to find a low mileage M52 cheaper than an S50 but there's the added parts and time required to convert everything. PM me if you have more specific questions and I'll give you the rundown.

not my best by far but you get the point.

I agree that there is the right way as I too have been a bmw tech for over 10 years and have training on e36s to our s85's(which like to drop valves) not every motor needs all those parts and thats why engine builders get paid good to replace whats needed and not shoot every part just because it might have a few miles on them. most of us know that many of these motors will way out last our cars with the current rate of destruction so I don't believe in spending money (unless customers want the extra extra insurance) when funds could be stretched to other needed parts. to add a little up 1k for head 1k for bottomend (which is way over priced) is 2k total and you got a new motor, not 5k. lets rebuild these great cars one at a time without trowing our hard earned money out the window(again not saying you are) i just like to give people educated choices for themselves to make.

WTF, my machine work alone cost me 1+K, not to mention all the gaskets, seals, bearings, bolts, rings, pistons, the actual engine, and a bunch of other stuff. 5k is pretty dead on.

yeah I want to know how you do a full rebuild (not just a reseal) on a 24v head for $1000, parts and labor. lol.

smexy 0 mile crank?

He's spending $1000 on gasket sealer.

Look at those sexy hands.

I know! Lets finish this bad boy up!
