Recipe for near 4 digit horsepower numbers from an m50 or so?

[Exodus_2pt0]

Just curious, as in the next few years I'm looking to up my S4 whp by about 200 or so. I'm shooting for 600-700awhp, which is considered block cracking territory.

My car has been ridiculously easy to get to around 450awhp. Now all I need to do is throw rods in and a nice big single to take it to the 600range.

BUT!

After that, I'm pretty much done unless I swap a vr6 in, which I don't know if I care to do that.

So, I admit I am a horsepower junky, and I'm getting to a point in my life that my goals aren't so unreachable, but I don't want to spend a whole ton of money and come up short. So far I've got a lot accomplished on little cash, but that will not hold true when I rebuild the engine and go stk.

If I were to say, sell my S4 and pick up a very clean m50 swapped E30, what would I be looking at to support near 4 digit whp numbers? Specifically engine/drivetrain support modifications. I can get the air and fuel in there no problem.

Also v8 swap is a no go. Been there, done that. I like small engines with big snails.

Can't contribute much more than the thought that 700+whp in an E30 would pretty unusable unless the car is drag-prepped like Good & Tight's 10 second Turbo M30 powered 318.

Unusable unless you like to do insane burnouts that is.

Are you looking for traction on the street or drags?
One of the e30 s52 turbo cars I used to idolize couldn't get traction with 315 hoosiers even with Racelogic's traction control on 640wtq and went Corvette C4 IRS to fix it.

640wtq @ 3700 RPM does things. :^(

If you refresh and properly fasten an m50 bottom end I dont see why 1000+ isnt reasonably achievable. many have done it. M50 is a fcking beast engine.

Yea if I went this route the car would be on drag radials 24/7. I think AWD has spoiled me, I wasn't really considering traction.

How about the trans?

I may just finish this car up and see where I ended up. Problem Is I get bored, not that the S4 is boring, I just can never settle on a vehicle.

First world problems...

Nisse is making 700awhp on his M50. I don't remember if it's stock internals or not.

[ThatOneEuroE30]

Talk to my buddy vlad? Im sure he'll let you know how to get 1000hp out of your audi his 900whp one is up for sale for 16k

Looked it up, no stock internals.

>500hp from an s62 is good enough for me.

You can never have to much horsepower.

I would definitely talk to Nisse he has two M50 e30's that are over 700 hp. One 764 HP RWD and one 720 HP AWD.

The aforementioned turbo M30 powered 318 owned by Otis (Good & Tight) is an all out drag car, but on the street lacks traction and makes... 550whp? or so. A lot less than you're talking about. He babies the thing on the street because it's just an insane car (ran 10.08 @134mph in the 1/4mi). I can't imagine driving an E30 with more power than that. The suspension geometry which toes out and cambers in when it squats, the lack of space for giant supercar-tier wheels and tires, it just seems like it would have no traction at all.

I say do it! :up: :popcorn:

You can easily make 700hp reliably from an M50 block with S52 or M52 crank, forged internals a must. Stock tranny will not last long, stock axles will snap like kit kats, drive shaft will twist like a twizzler..ect.... More than enough to scare the crap out of anyone.

I've seen most M50/S52 in the 800-900hp+ build not last long, either lifting heads, blown gaskets and rods.

slightly off topic, but what is everyone's opinion on ARP hardware? kind of seems over the top for most FI builds, since many junkyard blocks are out there pushing big numbers. I just recently was enlightened tothe extra machining precautions to use high clamp load hardware such as line boring etc.

anybody have some first hand input on this?

Which M50 would you recommend for that? I would imagine Vanos tuning is a bitch?
