What engine makes E36 M3 loads of power?

In reply to Dootz :

Really ?  I hadn’t heard that, ( 4.2 Atlas ) you do know the origins of that motor don’t you?  

460 Ford is another big one to add- stock cranks can handle ~700 HP with some decent reliability per PowerNation.

The Honda K-series has a few built to 4-digit horsepower for drag cars, though god knows *how* much boost has to be built to do so. Also to add from some Aussies- the Toyota 1UZ-FE. 8 bolt mains. And if you get an early block (see attached) you get thick rods and a stock forged crank. Al of Mighty Car Mods has stated that the biggest problem with the engines is their exhaust valve angle- it's 25 Degrees, making it VERY restrictive (though some fans have reduced it quite a bit) second to the pistons themselves. They DO have an aftermarket, though cams will easily run you a grand and a half.

I have a feeling that it's less the angle, but the fact that the valves are somewhat small in the early 1uz. If I remember right they were over a mm smaller than the 2jz. The vvtis got a thinner stem and similar sizes. As for op, Paisley was making 800+ hp on the stock bottom end in the 90s with the 2jz.

All I heard, sorry, could you repeat the rest?

Compare size, cost and power potential.... nothing beats the LS for a complete package, nothing.  

Now a well built Audi or Japanese engine is awesome but it will always lag behind an LS in at least one if not two or three of those criteria.

Sorry, they're 6 bolt mains, not 8.

Thanks, I just read (most of) this epic thread over at Rennlist because it was linked there, and am now thinking about 07k powered 944 projects...

I knew about the 07k, got out of the Audi game and just bought an UrS4 so I'm unearthing all my old forum log ins and knowledge. Looks like a lot has happened since Hank started Iroz, I remember when he was just finishing up the Ur-Quattro and reading about it on Motorgeek. I didn't realize he started his own forum, though it makes sense. Thanks for the info!

I thought I recalled hearing the offshore powerboat guys loved the 1uz cuz they could boost em to 4 figures and run 'em all season without expectation of breakage...

Can here to say toyota 1uzfe. Stock internals are good to about 500hp if you have the early engine. Although I saw an internet video that claimed 800hp on stock bottom.

Isn't theV8Kid making close to 1000hp with his LS turbo?  

Here's the GRM thread where he even runs it on a dyno for a 1000 whp target- and he's really close- https://grassrootsmotorsports.com/forum/grm/drag-week-2019/156119/page2/

And it's more stock than I would have imagined.

I think the HRM article pretty much proved the LS is the best option.  1,203 horsepower on a cheap junkyard 4.8, with just some head work, a cam, intake, and two turbos.  I haven't seen any other engine mentioned yet in this thread that can do that much with only a handful of mods.  And they're super cheap.  Ugh, now I want to LS swap something!

I have a few VR6s in the 700-800whp range on stock bottom ends, with just arp studs and rod bolts, well over 1k with just pistons on stock rods. Getting real transmissions to fit to these is a pain in the rear.

Ahem.





1250 HP.  Back in the '60s...

4g63-ish inside....

?

But they aren't super-cheap doe

In reply to Knurled. :

IThe 07K peeked my interest. That's the kind of unknown to me engine I was hoping to learn about. Surely they can't make 20V top end levels of hp though. 

This far and no one has said f2t?

We are letting sw1 down. Also, the late nineties Saab 4cyl turbos can be very potent on stock motor + massive boost.

Not on a $300 junkyard engine with a stock bottom end that's widely available and 300K mile reliable.

All things being equal they should easily beat a 4cyl based 20v, or any of the FSI 4cyls. Big issues for them are parts availability (camshafts, etc). Engines are cheap for sure. Just had a customer put one into a Vanagon that will get a mild turbo setup once we work out some of the quirks (tach etc).

If they are, I'll take two.

In reply to Paul_VR6 :

If b be interested to hear how that Vanagon works out. I was referring to the 5 cylinder 20v of the late 80s/ early 90s. I know, I need to get with the times.

There is already a SFWD prepped Mk3 VW running high 8's, so well over 1000hp at the tire. Not sure where the "old school" ones top out, but I am sure the new ones can do more with the better head design.

They don't.  They make much, much more.  An untouched Jetta head flows more than a max-effort ported 20v., the bottom ends are better, everything is just better.\

Downside:  Even though the 07K has the same bore spacing as the 034 block, a header for a 20V won't fit.  Apparently the 20vs have an asymmetrical port pattern for some VWAG reason (might have been for clearance reasons on the Sport Quattro where the design originated) and 07Ks have symmetrical.

Those old Hemis were also dixie-cup motors.  Lots of stories from the old timers about having to keep a floor jack under the engine to keep the crank from falling out, running to junkyards to get another bottom end to swap in at the track, etc.

That's a lot of why it is comparatively easy to find heads but 392 blocks are scarce.  The drag racers blowed 'em all up.  Granted, this is because the heads could flow, so they took extremely well to racing.  The bottom ends, however...
