Need help building 2.0LR or 2.2LR Evo 9
How she sits at the moment
What’s up guys,
Been out of the evo game for just over 5 years now and I’ve forgotten most of the things I had learned about these cars haha I need some help with selecting some parts for a build I’m about to do in my Evo 9. I see there’s a few options for pistons and I have no clue which ones I need for this build. Evo 9 block, didn’t blow it or anything, so do I run standard size pistons, 85.5, or 86? I’m running a 156mm rod for either build so that’s pretty straight forward, and a 88mm for the 2.0LR build and a 94mm for the 2.2LR build. I’d like to get around 9.5:1 CR as well. What’s the latest and greatest for parts? CP? Manley? Mahle? Carrillo? Oliver? Mil.Spec? K1? If I go the 2.2LR 4G63 block route do I need to notch the block? I dropped off the head at Port Flow Designs yesterday to get it taken care of, so I’d like to get these parts picked out so I can drop them and the block off to get this done ASAP as well. Car will be driven on the street 10k miles a year or so plus some road course events every couple months, so I’d like to stay with steel rods vs aluminum rods as well. Any help/advice is appreciated and thanks in advance guys!!!

U want to machine a virgin block send it along with arp main studs and your pistons so they can machine it to your desired ptw...(. 10 or 20over depends) I would choose wiseco pistons, Carrillo rods, OEM crank if 2L.

From what I've been told the 156mm 2.2 using a 63 block does not hold up as the pin is too high and cuts into an oil ring.
The latest and greatest motor these days is a 2.2 consisting of a 94mm crank 153mm rods and custom height pistons. My block is sitting at ER currently and thats the motor I'm going with.

I would have to agree with heel2toe. The best of both worlds is going to be a 2.2. The rod ratio is good and you can rev it high while spooling a larger turbo, faster. There could be debate over specific parts, but I understand that a K1 Billet crank, Manley I-beams or Carillo Rods, Wiseco HD pistons and ACL bearings make for one of the strongest "off the shelf" rotating assemblies you can put together. You might have to give Wiseco a call to obtain the correct piston wrist pin height depending on what rod you use. An eagle crank might be good enough for your build, but if you're making more than 600whp, I'd recommend a billet crank. I'm using a Manley Billet crank with my 2.3 and have had good luck with it personally.

Personally I would source a 4g64 block for the additional deck height. IMO an ideal setup would be 4g64 block, 156mm rods (longer if possible), 10:1cr pistons, and 94mm crank.

That being said, OP, you can not run a 156/94 in a 4g63 block. The pin height is too short, putting the pin too far up on the piston and it causes problems. Running a 156mm rod with an 88mm crank is pretty pointless, just no need for it. The stock rod ratio with 150/88 is fine.
My suggestion is a 153/94 in you 4g63 block (custom rod and piston), or a 156/94 in a 4g64 block (just a custom piston). You can also do a 159/94 in the 4g64, but it's not needed (156/94 rod ratio is more than fine) and adds expense with needing a custom rod again.
I would also only go with 9:1 compression. It keeps the head gasket happy.

Pistons for the 94/153 combo are not custom height. Its the same height as a 2.3 stroker, or 2.0 long rod. The dome volume is custome to correct compression for the stroke.
That being said, OP, you can not run a 156/94 in a 4g63 block. The pin height is too short, putting the pin too far up on the piston and it causes problems. Running a 156mm rod with an 88mm crank is pretty pointless, just no need for it. The stock rod ratio with 150/88 is fine.

You have to source parts regardless. You're going to compromise you're engine build/potential for a little hassle? It's as simple as calling or emailing ER, saying you need pistons and 153mm rods to build a 94mm stroker in 4g63, tell them what bore you want and compression. And they ship to you. ER also uses their proprietary piston specs, so you're getting a much better part than off the shelf Wiseco HD's. If your motor didn't blow up, you will likely be fine with 85.25mm pistons, or 85.5mm will certainly be fine.
If you want it really easy, ship the car up to ER and have them build it and return it running condition.
And, again, if you're going to build a 2.0, use the standard rod length. The stock 150/88 has a 1.7:1 rod ratio. It does not need a longer rod.

They're only going to be in Texas for the weekend.
Regardless, you're probably only going to build this motor once, don't half *** it. If you want a stroker, make it happen. It'll be well worth it.
