3sgelc plus turbo build project

Ok so I have been following this forum for a longtime and finally joined as a new member since I have everything ready to start my tear-down and rebuild. I do however have a couple of questions I didn't see covered in other threads so i thought I would start a new thread.

1) being that my gen1 3sge comes stock with a 6-bolt flywheel and I plan on using the 5sfe's s54 (or e153 if I can get my hands on one for a reasonable price), is it possible to swap my gen2 3sgte crank(w/ gen2 3sgte rods/pistons) into my gen1 3sgelc block?

2) would using the 3sgte crank and rotating assembly change my quench heighth? Since I will be boosting my build with a stock supra spec ct26... I am trying to take everything potentially harmful to my motor into account. Granted I can have my block decked to compensate for additional height to avoid detonation problems associated with incorrect quench. I would however prefer to send my block to the machine shop only once if possible.

speaking of blocks...
I have two 3sgelc long blocks at my disposal plus gen2 3sgte internals from donor mr2 turbo.

I am looking to make good use of the st185 clutch setup i have been sitting on and can't figure out which tranny setup will let me use the 8-bolt crank from the gen2 3sgte and 3sgte clutch.

i will have some time to work on tranny while my exhaust manifold, turbo exhaust housing, and downpipe are off at jet-hot. So any help you can give me in figuring this out is greatly appreciated. I will of course have pics and vids once I start getting into teardown.

 

Still can't find info on whether gen2 crank will sit snug in gen1 3sgelc block and mains. Anybody have length dimensions? I wont be at the garage for another week, so I can't physically pick the cranks up to compare. But I am starting to guess that six bolt and eight bolt cranks center with different heights and would use different main caps off the block. Is this correct?

 

Thanks for taking the time to get back to me. What flywheel/pressure plate setup did you go with?

 

Wow,
thank you Stig for answering so many questions with one reply.
i was thinking about using the Gen 2 3sgte cylinder head and keeping the 3sge side feed intake as they both use TVIS and it seems like the ports match fine, since I have already mock routed the fmic, I feel comfy with that idea. I know gen1 gte camshafts came stock 236 and gen1 ge with 240. Did the gen2 gte camshafts come with more aggressive camshafts? Would there be any advantages to swapping camshafts or am I looking at machine work on head and camshafts?

sorry to keep asking questions. I really appreciate the time everybody takes to share knowledge and save other people from possible disasters. Since I am not after huge power I was leaning towards the s53, I am working on sourcing that, I haven't had much luck sourcing a e153 close to Seattle though.

 

Still prepping

Still getting prepped for the actual teardown and rebuild. I went ahead and bought ARP head studs, main studs,and connecting rod bolts. Cometic MLS gaskets for TVIS, intake manifold, cylinder head, and exhaust manifold are my plan. I found a nice package online for only $189.00 for everything. I still have to think about the transmission setup. With the turbo and aftermarket manifold I don't know how tight a squeeze it will be for the starter on my s53. I think the e153's have the starter mounted outwards of the bell housing so I wouldn't have this problem if I can source an e153. Exhaust manifold, housing and downpipe will all be thermal coated to keep things cool and keep engine bay temperatures down. If I am lucky I will source a fwd e153 and get that mated up to the block with 3sgte internals, and I can keep the s53 to mate with the other block using 3sge internals. Two engines and two transmissions would be great.

 

I will have to test the manifold out and post any clearance issues. I know it sits the turbo further out from the block, but I don't have exact measurements.

 

S54 bellousing around 3sgte pressure plate?

So I am pretty sure I have seen this same question here on the forum, I may have even asked it already, but cant find the answer again.

Does the 3sgte pressure plate fit inside the S54 bellhousing?
Will it work well in holding pressure under load?
I have read the S54 is good for up to 350 hp...
Thanks!

 

Tranny

There was a caldina engine-tranny up for sale on a US based JDMEngine Import company, but I havent seen it for a while. It was for 3sgte flywheel and fwd w/lsd. I think it must have been similar to the MR2 and Camry boxes... is it called e56?

Also, it seems my tranny splines are to small for the 3sgte clutch. Sucks right! Gotta find the 5sfe clutch disc to sandwich in there.

 

quick update

Quick update for you all. Finally have the engine rebuild finished and back in the engine bay awaiting wire harness and ignitor along with transmission to be hooked up.
I was trying to find the thread about breaking in fresh rebuild and couldnt find that. Any help?
Pictures soon to come!
Thanks for all the help

Ohh, I picked up another celica gt-s... $600 for a beauty with all leather interior, abs, climate control, soon as I get my project celica out of the garage, I am going to drop my spare 3sge block (rebuilding bottom end right now) into that and wham... a great daily driver for the wife with abs and peppy little motor. Its a hatchback not a coupe, love that sexy rear end on it!
