M20 engine build

[Andy.B]

Having actually owned and driven a 2.5i, 2.7e, and 2.7i, I will say that the 2.7i is better hands down.

I do not understand all the workbench engineers who love to chime into every 2.7i discussion to slam it. Is it a hp monster? Of course not. Is it better than a 2.7e? Absolutely. Is it the best hp/$ investment you can make in an eta? You betcha.

Throw a cam at it, and you have a strong na engine for very little money invested.

My point is, try not to get wrapped up in chasing what engine option looks best on paper. There are too many variables, and there is always a 'better option' for every upgrade, if only you're willing to spend a few dollars more.

A 2.7i can be done with no special tools in a weekend in your driveway. It will breathe new life into a low revving eta. It will put a smile on your face when you drive it.

it made 150whp/148tq.

For a measly 140hp, lost compression and a wasted weekend, I'd rather keep a chipped eta.

Its not horrible but people really overstate the HP of M20s.. I constantly hear they make as much power as a M50NV.. Going from an M20 to a 24v is night and day IMHO

Pretty sure he's building that 2.7i for boost not NA

[delamaize]

if you wanna trade that M50 for my dissambled M20B27 short block, I'm game.
:D

True story bud, the 2.7i is an awesome upgrade if you plan on boost in the future. Most of the eta bottom ends I've torn down look a lot better than the b25s with the same mileage.

Lower rev's perhaps?

[e30josh]

Definitely what I assumed... Lower and slower revving does a lot of help to bearings and rings in the long run.

Could also be the fact that the etas weren't driven as sports car until fairly recently, and probably serviced/treated better throughout the life span. In my experience, etas have less cylinder leakage as they age.

Probably the reason why you see more b27s with over 350k

Definitely. Less turns = less wear.

Its a nice upgrade that you can do in your driveway with no machining. Im doing a m52 crank m20 build now. Cant wait to be done with it :)

m50s cannot take the abuse m20s can.

[EN318isPDX]

I fail to see any logic in this statement

Dude let the kid build his M20. Cmon now, we all know you guys love 24v but this thread is about the guy wanting to build his M20.

People may not like the same shit you do. That's quite okay.

This thread is months old and OP is nowhere to be seen! I am not a M20 hater I just get tired of people making statements like the above. M20 is a great engine but not godlike.

Happy Thanksgiving Paolo
