What "bolt ons" bring an s52 to 300hp and what's the cost?

[e30polak]

IP races s52s average between 260-310whp. The higher the power NA, the shorter the usabel powerband. You will fail, I put money that you wont break 300whp NA. :roll:

If we could use the 3.8L crank and pistons from an s38b38, then I already would've started, but you can't. Without increasing the bore and stroke of the motor significantly, you will be shit out of luck passing 280-300whp. :p

You bitch. Foiled again.

Many many hours, tears, and blood will go into this engine, but my goal should be attainable.

S54 race motors run something more like 435whp.

i, for one, cannot wait to get a little tast of your skills

[BimmerTim]

So you're going for a dyno queen, not a usable powerband?

I will have plenty of usable power.

Better yet, I will give you a reach around. Although you and/or I can wear a medal while this is performed, if you'd like.

I would prefer if only I wear the medal. I feel more special that way.

What is your basic engine build plan?

Pretty much everything you can think of, and probably a few things you can't. Think outside the box guys. I don't build cookie-cutter bmws here.

Yes, that's totally it. My one and only mod. You have me down to a science, chief.

wow, you sound like a real pro. you should call will turner. he probably has an opening for you.

Poke fun if you want. The cars I have under my belt will show that I am no amateur. I am mechanical engineer, and I have been around cars since before I could walk. My latest pink fendered E30 is the platform and though there is still a ton of work to be done, even in it's current stage is no slouch.

Given your rear bumper is/was a pressure treated 2x6 (which btw, I love), I am going to assume your budget for engine development will be a little on the austere side.

To temper your expectations, take a look at racing engines. A race S54 can actually achieve 350 whp, but then again, it also costs $20k, and the head is actually designed to support that airflow.

I'll find it and I'll let you all know.

If there is one thing I know, it's how to get hidden hp out of cars.

Probably, but 350 is 350, no matter where in the revs.

Perfect. Will you give me a medal when I do it?

Nope. S50B30 out of a 95 M3, with 204,000mi no less.

The only way this is happening is at high rpm, 8000 or more I'd wager.

Marking your words for future reference.

maybe he meant S50B32?

I promise all of you that I will make 350whp NA out of my S50. Mark my words.
