m20 or m42?

[nando]

I can't see an M42 build costing less than an M20. No way. you can do 300whp on a bone stock M20B25. To do 300whp on an M42 costs significantly more, and requires more boost, not to mention the turbo aftermarket for M42s is far smaller.

is it a better or engine or not? I don't know. But there's no way that an M42 will cost less for a given HP level.

what motor can i get the most useable fun out of for the cost?

m42

You all are confusing the Goblin (OP). LOL

lol and yes I am a bit confused

[ApexGoblin]

wow its a pretty split opinion here from what im reading.... maybe this will help narrow down what would be a better build for me...

what motor can i get the most useable fun out of for the cost? i seem to be getting mixed opinions in this regard as to which motor itself is a better platform for achieving my power desires reliably.

buttchug you obviously know a thing or two about turboing an m42 what was your experience with the build? i believe you mentioned it costs more? why is that?

anyone else with a turbo m20 (2.5 or 2.7) what are your experiences/costs with your build? and what were the results you were after? what results did you achieve?

It seems that I dont have a ridiculous idea of a power goal, im just trying to iron out which is the best way to get there. if there are any more specific bits of information im leaving out that may help please let me know. i really do appreciate all of the thoughts and opinions!

they weren't used, they were "seasoned". :p

:up: +1 for a better choice of words! ;)

[nando]

if your going for fun factor m42 would be the way to go. its all about usable fun power than can be used daily on the street. granted m20 with boost falls into this area as well, its not really a choice of engine its a choice of build direction.

What does the OP want. maybe 10-12 psi m42 which would give 240-260 hp spooling at 2500 somthing?
orrr turbo m20 which gives maybe 40 more hp and is spooling at 3k or so? provided the builds are somewhat proportional and similar...

OP do what you think will be the most fun. Just dont not do anything and be gay. my 2 cents

I don't know where you're pulling these #s from

[slammin.e28]

Fixed for you.:)

IIRC those were USED blocks too, that had sat around a while.

[Ryann]

They got 1300hp out of an M12.

Fixed for you.:)

listen betch stop being a pussaay and turbo a m42

amen!!!!!!

[BMC227]

Just say fuck M20, fuck M42. Get an M30, boost it, and roll on with life.

word.

[nando]

yeah, a home built 10,000rpm 600hp M42 is totally realistic. :p

[bmwguy325is]

I say build the M42 so it will spin 10K and boost it just like the old 320s did. They got 600hp out of an M12.
