How about a 1225 hp BMW E30 S38 turbo swap? 9 second Precision PT8285 turbo S38 E30 3-Series on E85 by Boba Motoring

[Sticky]

Have you heard of Boba Motoring? They are a German tuner that just kind of goes crazy stuffing a ton of turbo power into older German cars. For example, a MKII VW Golf with a 4Motion all wheel drive system retrofitted to help put down 1150+ horsepower from a turbo 2.0 liter pushing 58 psi of boost.

Yep, crazy stuff. They do not just do VW's but decided to go all out on an E30 BMW. They swapped in the S38 motor (the best BMW M motor of all time) and gave it a top mount Precision PT8285 turbo. With E85 fuel the result is 1225 horsepower at 33 psi of boost. And yes, unlike other German tuners they provided the graphs to back up the claims.

If the graph isn't enough there is also the car going 9.19 @ 159.53 miles per hour in the 1/4 mile. It helps that it only weighs 2912 pounds but also keep in mind you have to row your own gears.

While guys on the forums debate the N54 vs. the N55 or the S55 motor the older M inline-6 engines are blowing them so far away it isn't even a contest at this point.

N54 what?

Love these guys. That 16V vampir golf is awesome and this is even cooler.

[Sirdaft1]

"N54 what?" is right. I need one of those in my 335.

$4k... not bad.

Looks like she may need a rebuild. Probably not a bad idea to do anyways.

**ponders swapping it into his e30 track car...**

Just my opinion, but I can't get excited on a 204 hp engine, no matter how "storied" it is. Maybe in a light weight Miata or Datson 510. Better yet, turbo it.

[G0TB00ST?]

You can't get excited about an engine over 20 years old that is still relevant? Not to mention this 20 year old engine is making well over 1000whp when some of these modern engines are struggling to break 600. Granted it's had more time for RnD, but still this is an "out dated" engine making 4 digit power. I don't care what engine it is or what power it makes stock the thought of an engine having that kind of potential get will get my dick hard any day.

That engine easily puts out way more than that even naturally aspirated. You can get it will into the 400's.

310 hp stock for E34 M5 US. You are saying you can get to 400rwhp reliably on NA engine? Pray tell.

400 whp NA S38's have been done but I was talking crank there. Low 300's is basically nothing out of the motor and what we were given stock.

Here is just a tune, 320 whp:

awesome! mines never gonna touch that

[The Ghost]

Awesome! And think of how light it Is.

I could be wrong, but I'm pretty sure it has an iron block. So it's probably about the same weight as the s54 give or take a few pounds.

I believe he's referring to the E30 chassis.

Ah, the Peruvian tune.

Hey S38 graphs aren't exactly in abundance

When I have time I'll look for a 400 whp na graph.

Lets make it clear weightwise!

S38B36-151kg +/-1kg Cast Iron Block
S38B38-151kg +/-1kg Cast Iron Block
S50B32-152kg +/-1kg Cast Iron Block
S54B32-148kg +/-1kg Cast Iron Block!
S62B50 V8-168kg! +/-1KG

No dyno graph but the mods involved to get there NA.
