2.4 split thrust

[TWOpointFORliter]

So I am looking to have another 2.4 built since my last one sent the rod through the block. I’ve always read and understood that all 63 and 64’s post mid 97 are split thrust blocks. I ordered a block from miller imports to have built and he has informed me that all 3 of the blocks he has pulled from 98+ spyders have NOT been split thrust blocks. Is the split thrust 64 a myth or does he just happen to have 3 98 spyders without the original engines?

I thought only Late model 98, and 99 were split thrust..

Mid 97 is when they made the switch on the 63’s. Can anyone confirm they actually have a 64 split thrust?

I have a 4g64 short block from a 99 GS in my garage, I'll check to see what bearings it has in the next few days.

I have one 4g64 & it's split trust

 

[import solutions]

I had a split block

Well I guess I will just keep searching then. I have the money and all my other parts for my build. Only thing I am lacking is the block. It’s becoming frustrating trying to find one. I want my car back on the road!!!

They are right they do exsist. Block I have is a split thrust from a late 99

I have a 99 spyder 4G64 split thrust block and a pristine 4G69 crank in my garage right now. Might sell them for the right price.

What about the 2.4 from a 3g eclipse? Did those have split trust bearings? Mitsu didn't mirror the 4g64 block like they did with the 4G63, only the head (starter on a 3g eclipse is in front under the exhaust manifold), so it should mount in a DSM right?

I was also under the impression the split thrust bearing change for the 4G63 came midway through the 98 model year. edit: i was wrong on the date, for a 4g63 CAPS lists build dates > week 1 of June '97.

Similarly, 4G64 lists the same change in June of '97, so a Spyder with an engine built later than June of '97 SHOULD have split-thrust.
