My car is starting to get to the point where it is time to say good bye to my stock bottom end and start the planning process for build motor. I have been doing a ton of research on this and from what I can tell then best option I have seen in my opinion is a 2.2 super long rod stroker.

Main reason I have decided to go this route is because I was able to pick up a 4g64 block and crank pulled from a running 00 Eclipse with 90k on it for super cheap. I figured if I use that block to build a motor that I could always used the 100mm crank from it and my stock block to build a backup 2.3 motor incase of a failure in the primary engine.

Thus far I have a bit of confusion in the motor. Crankshaft being the first. I've some places saying I need a 92mm crank others saying a 94mm crank. So which is it?

I'm assuming from my studies that I need to get 162mm rods for this build as well?

Lastly what size pistons am I going to require on this setup?

Any and all help is greatly appreciated.

 

The easiest one to build would be 94mm crank, 156mm rod, with a custom piston with wristpin moved up 3mm. all manley parts and all direct bolt on friendly. still has a decent rod ratio of 1.65 and almost 12% displacement increase vs a 2.0L

I've built others with 94mm crank, 159mm custom R&R rods, and 6mm up wristpin on piston off the shelf stroker piston.

The one above required chamfering the ACL bearings though to give enough clearance on the crank.

Send me an email and ill sell you the parts you need at a good price tscompusa@gmail.com

If you're building it yourself, you can just buy the parts from me, if you need a builder I can build it also. I've done about 50 engines now for my customers all with great success and they do not consume or burn oil or have piston slap.

162mm versions are not reliable at all, and i would not recommend it. It requires moving the pin up way to high on the piston jeopardizing the pistons oil rail support.

The only time id recommend a 162mm rod in a 4g64, is if its with a 88mm crank aka 2.1L

You could also do a 160mm rod with a 92mm crank with stroker piston. 9% displacement increase 1.7 rod ratio.

 

This is what I have, so much fun with a FP Red. Around the neighborhood of 550/505 on E85, fuel pump and injector limited.

 

Thanks guys. I think for the time being I am going to just build a 2.4. Once I get the 4g63 block out of the car I think I may have to slowly work up to this. 2.2 with aluminum rods and a precision 6466 would be a blast.

 

You can do that with the 2.4. Get the 156 rods and custom pistons. I think there might be an off the shelf piston as well for that setup. Get the turbo tuff rods.

I shaved my 64 crank to make the rotating assembly lighter. Revs awesome now compared to my last crank that was stock. I forgot to weigh it before I put it in.

You will like the torque from the 2.4.

 

Yeah i know i can. I honest got the block and crank for cheap so I just wanted to budget motor for now with the 2.4. Don't really want to put a lot in to ordering custom parts. I'll wait to im a little more finically set before I start throwing money that much money into it. lol
