How to 5SGTE - 3SGTE Cylinder Head Swap on your 5SFE Block

[RobStevo]

Fantastic write-up! I just want to double check about the cooling jacket issue to make sure I understand correctly.

If I have a 93 Rev 2 block, would those jackets align to the same year GE head?

Similarly would a 91 Rev 1 block, also align to it's same year GE head?

And just lastly, you mentioned the 98+ 5S matches the corresponding GE head, aside from the reinforced block, are there any other advantages of purchasing one over an earlier one?

I have both the 93 and 91 blocks on hand, and don't think I'll be looking at anything over 400WHP max, so would these be suitable, or would I still need a sleeve/98 block?

Much appreciated and hope this great thread stays alive

50/50 of that happening.

Same as above.

None but as listed.

You're fine with what you have. Personally, I would go with a 98 block. You don't have to spend the extra to machine it plus it comes with the reinforcement you need in case your block doesn't hold out.

Added 5SFE Rear Main Seal since most of the seals, gaskets, and o-rings are 3SGTE.

nice thread dude.

Added TVIS delete in recommendations. Also included notes. Also previously forgot to add it to required parts.
Added Polyurethane motor mount recommendation.

Can we use a 3SGE head? I know its been its probally been said, but I want to clarify....98+ means direct bolt on with no machining what so ever with any 3sgte head?

Yes you can use it with a 3SGE head and it has been done.
It is direct bolt on.

The 5SFE comes with a forged crank plus the 2.2L displacement so that's the way to go.
If you can get your hands on a +98 block, then you'd be set. The cylinder walls are thicker than earlier year 5sfe's and you can overbore more on a 5S block than a 3S block.

Edit: transmission swap info further updated.

I can see a machinist making the journal smaller in diameter, but is it possible to widen it also? Why not just get stonger rod bolts and use the existing 5sfe piston rod setup...

See post #23.

Because the small size of the rod bolts completely defeat the purpose of making a stronger one.

Although I can see the relationship with size and strength, isn't it possible to use a rod bolt that the same size (in respect to diameter) but engineered to be stronger....its what they do in the Honda's... they replace there rods bolts when boosting because its the weak point in the engine....

I would presumably say "yes" given the fact that it is suggested that BC 5SFE Rods are the only safe 5SFTE rod to go with. Given that, I do believe BC uses ARP hardware on their rods.

Added "Mr2 and camry tranny" link under Transmission Swap Reference Information on pg1,
I got tired of seeing incorrect info on this so I decided to finally set the record straight on it.
