Time lapse complete build of one of my favorate engines (attn Jlee)

[exdeath]

Thanks for the comments guys...didn't see this thread until now. I'm tdc7 on youtube and the black and red MR2 in the video are mine. Red one is a 93 hardtop with JDM gen 2 3s-ge (high compression motor minus the turbo, 165hp @ crank)




You must be "DaleRider1954". The block is a 5s block...look at the oil cooler lines. Pistons are 87.5mm Wisecos, and the maximum bore on a 3s block is 87.0mm.

Nope that's not me on Youtube. That person copy/pasted that from this thead to sound cool or something. LMAO word for word copy/paste.

I didn't really notice or look for anything else, staring at compressed youtube video for small details hurts my face. I just noticed the water jacket right off the bat. I see the difference in the oil cooler now (3S has a line on the left side and the one on the right makes a 180 deg bend straight up).

What year/model 5S block did you use and what machining was required? I can't get a clear angle in the vid but it looks like the 5S water ports would have to have been filled and then 3S cut, since the 5S holes are in the middle and it's not a simple as just adding the second hole. I do see that the material between the water holes is darker than the rest of the deck, welds?

I didn't notice a balance shaft gear on the crank either, is that machined away when the crank journals are cut down, or do the MR 5S engines not come with that gear since they don't have a balancer?

Always wondered what it took machining wise to mate a GTE head to a 5S block, vs just buying a ATS stroker short block. Thanks!

91 5s block, just machined the crank to 3s rod specs and bored the cylinders to 87.5mm. $360~ in machine work. I guess the earlier 5s blocks don't have that but I've seen it in later years I think. Since I used a 91 block, the 3s head mated without any water jacket problems. However, I didn't have a knock sensor bung (used an 89 camaro KS instead) and was missing cooling for the turbo. Removed the coolant to the ISC valve on throttle body and used that instead.
