M20 Bottom End Build

[SeanE30]

Looking for solution to which pistons, rods, or stroker kit is the most "bang for your buck". I know ireland engineering has great prices on all. Looking for a bottom end that can support high boost off a turbo and alcohol. Post up your best deals you've found or your parts you are selling!

I've looked at their page and they do have some deals but ie still comes out on top. I'm looking to push around 20-22 lbs on e85 with my car at about 220,xxx + miles because odometer broke at an unknown time. I've done headwords welded coolant lines, resurfaced, and have ARP's and mls gasket. Looking for the high 400's to low 500 hp range using a MS2 from whodwho. I have everything turbo, fuel, management just need a tougher bottom end. Is the ie stroker still the best deal around here?

"best deal" is pretty relative. If you're looking for an off-the-shelf kit then I'd say its a good option, but I am biased because I'm preparing to run one and happen to work @ IE.

You can piece it together cheaper yourself certainly (and just order pistons from IE), but the chances of success are variable to your experience and confidence. What someone says is easy or difficult on an online message board may or may not apply to you. Sounds like you've done most the grunt work already (whodwho setup, etc.).

I've been doing a lot of digging for a while and making sure I have everything ready and set for a turbo to handle some boost. I like IE because everything's affordable compared to competitors and it looks like from others hat the quality is great too. I'd like to stroke it to a 2.9 but if I could use pistons and rods and go that direction that would be nice too. Just on a budget but if I need to, I'll just go with the stroker kit in the end.

sometimes one CBF looking around for parts and a kit fits the bill even if it cost a bit more.....

there are heaps of places that do all the hard work for you and will sell M20 aftermarket pistons. IE, VAC, MM, TE, PB.....

with rods Molnar are a economical brand if you dont want to pay top dollar for the big name brands or want something a bit better than S52 rods.

S50/S52 crank, S50/S52 rods, and custom Ross pistons to your spec through IE.

This is the cheapest way to do it.

If you want to make serious power you're going to need head work too.

S50/52 crank and rods can handle 20+ psi, E85, and a heavy cam? and head works all done and good.

yes, but you'd be safer and the engine would comparatively last a bit longer with an 84mm stroke (2.9L) setup. Frankly you'll find a million opinions out there, there is no cut and dry / right or wrong method. It's the blessing and curse of message boards.

And I do see that S52 rods are the same 135mm length as the M20b25 rods but the stroke of a s52 crank is 89.6mm compared to the M20's 74mm stroke. what would I go about to complete something like this? i know it would because something like a 3.0 liter stroker am I correct?

Couldn't have but it any more straight forward. Thank you
