M50 vs M20.. for boost. whats your opinion?

[IronFreak]

I think its the fact that you have a similar displacement, thicker walls but overall less weight.

You say that now. I'd think an m54 would be a great motor. Has s52 crank and more wall thickness IIRC. Plus aluminum block.

What's the benefit of an aluminum block vs. iron on boost?
heat dissipation?

[IronFreak]

This is why M52

Even a stock m20 or m50 with MLS+ARPs can handle 400whp ..

M20 is at it's peak limit at that number without being "built" or meth introduced.
And the power delivery isn't as fun.. It'll be a dog out of boost.

Waiting for the S5x crowd to chime in...3...2..1...

Too much $$$ for something the m52 can also achieve.

Talk to this guy, grsmonkey.

He has done both successfully with good numbers.

I'm surprised no one has yet!

But I personally wouldn't see a point as I will be rebuilding either the m20/m5x... So what's the point I buying a $2500? S50 then to tear it open and spend much more $$$$

A stock M52 with a thicker headgasket and ARP's can handle 400rwhp all day long. No need to rebuild, plus you get the benefit of better gas mileage will not in boost.

Because of you're going to re-build with forged parts..

M20M2? + PERFECT tune + BOOST = BIG WIN

You'll never feel that you want more than M20!

Basically if tl;dr:

Why would you go m52???

Thats kinda the stuff im looking for..

Better economy and more capable than an m20 as Nigel mentioned.
More displacement than an m50, forged crank and rods factory(idk if the m50 is the same), thicker walls in between cylinders so less probability of a HG going and room enough for O-rings, and priced pretty much the same as an m50.
Also 24v is backed up by so many tuning solutions check bfc.

Since yours going through the motor, it's as reliable as you make it.

m52, shit on both for cheap.
