Rebuilding motor, need suggestions

[tmosser]

Well this will be my first motor rebuilt/build So I am seeing what everyone thinks, and can suggest to help me out. I am going to take everything out with the help of a good friend. (not my first motor removal nor his, as he is a ase certified mechanic and owns a build 2.6L srt4) anyways so I dont get asked if I ever worked on a car. lol. Heres what Im thinking after searching around and talking to a couple guys.

I am going to just rebuild the head and block since they have 115k on them.

thinking this for the bottom end

And do this as well

Or just send my block to map and do this

Just trying to keep price down, yet dont want so skimp on anything Im doing it right once so it dont have to happen again.

What pistons should I go with standard or .020 over? Or would that be something the machine shop has to figure out depending on my sleeves?

I wanted to do a 2.4L stroker but Nate at map thinks just re building the 2.0 would be best since it would last longer and just do 9.0.1 pistons would help spin it faster. Thoughts?

That kit has pretty much everything for the bottom end, Would I need to resurface the crank? Its fine right now, cars just running on low compression. Didnt even bother on doing a leak down since I want to just rebuild both top and bottom end.

What would you guys suggest for a head? I will re-use my cosworth m2 cams, and ARP head studs. IDK if I will bother porting it, I only want to make whatever I can with current mods on Shane's dyno. Hopeing close to 400. But I want something that would handle 450/500 hp no problem if I ever decide to upgrade the turbo. I really couldnt find anything on a DIY head rebuild so maybe just say F it and send it to map for new valves, springs, kiggly HLA, seals etc and assemble it with cams and such. So I can get it and bolt her on the block.

My best advice is to do everything through one shop so they're responsible for everything. MAP puts together nice blocks and heads. For what you're looking for, you should be just fine with a 9.0:1 MAP Stage 1 2.0L and a head rebuild with some mild porting. Your current valves can most likely be reused unless they're damaged, but they'll replace the guides and seats with the rebuild. While they're in there also get some upgrade beehive springs. MAP will worry about the overbore and crank; depending on the condition of your core they'll machine appropriately. Do NOT reuse your ARP headstuds, despite what you've heard they are once time use only and you do risk failure by reusing.

Check out this build thread for an almost entirely MAP setup I'm currently working on:

Why do you need a built motor on a stock turbo car? You can make plenty more power safely on the stock motor. Save your money ;)

[Kracka]

His compression numbers are low, from the PM with him sounds like he just wants to freshen things up.

[C3L1CA]

Couldn't he freshen up the stock motor though if he isn't looking for crazy power? New rings/ get the head looked at, maybe honed and some new bearings would be a lot cheaper than a full build.

I'm also kind of confused on how a stroker motor wouldn't last as long as a 2.0. Could anybody explain that one to me?

[goodhart]

Ah, that makes sense then.

Tyler, out of curiosity, what are your compression numbers?

Honestly, if you wanted more displacement, I would go with a 2.3 vs a 2.4 on an Evo. The head gasket options just kind of suck with 2.4's and they seem to have a hard time keeping head gaskets in them without o-ringing the block. Just seems like much less of a headache.

130-110-85-110

I will probably eventually upgrade the turbo later on which is why i want something that would be fine for either stock and possible stock frame upgrade (ef2 or fp green)

Im not looking on sending a ton just want a fresh motor and freshen everything up so i don't have to worry. I honestly don't care on power i just want something to take autoX days and dragging at pg2013

I would have to imagine it has to do with rod ratios and piston speed.

I agree. If you do want more displacement, the 2.3 seems to make more sense than the 2.4 since it retains the OEM block, crank, and MIVEC oiling system for IX's.

[Super Bleeder!!]

I have a nicely built 2.4 with a nice turbo setup i would be willing to part with for the right amount of coin.

[goodhart]

This is an Evo IX, not a dsm.
