Celica Forums General Discussion Engine and Performance 2ZZGE HEAD and 5SFE BLOCK.

I HAVE A QUESTION FOR GUYS.. ONE OF MY FRIENDS WENT TO CALI. COUPLE OF WEEKS AGO.. HE TOLD ME THAT HE SAW THIS SEAK 01 CELICA GTS .. THAT HAD A 2ZZGE HEAD AND AN MR-2 5SFE BOTTOM END, TURBOCHARGED.. IS THAT ACTUALLY POSSIBLE? OR ANYONE EVER HEARD ABOUT SOMETHING LIKE THAT? IF YES.. CAN YOU TELL ME A LITTLE BIT MORE ABOUT IT? I AM REALLY INTERESTED IN THIS IDEA. THANK YOU.

chill with the capitals man, lol

apologize about that.

hmmm interesting...

I'm not suer thats even posible lol I've never come across anything like that at the tracks I go to.

doesnt sound real to me.

I highly doubt it. Every now and then there are people that want to put a 2zz head on a 1zz, and although they are both 1.8 liter with idential bore pitchs , they are completely different engines otherwise. The 2zz (and 1zz) both have a bore pitch of 87.5mm. With a bore of 87 mm on the 5S-FE, and some metal between the cylinder walls, we could postulate the a bore pitch around 97mm. Essentially, the 2zz head is too small for its valves to sit over the pistons, let alone all the channels and head bolts. And there is no way to make it fit.

So i guess the guy was bullshiting everyone there .. hhhmmmm... anyways it would it be nice to have a Toyota Frankenstein engine..

very well said! he can probably get it to bolt up somewhat,but it just wouldnt work!

I don't think it's "impossible" per-se to build a Hybrid engine from a 2ZZ head/1ZZ block, but it wouldn't just bolt right together like the Honda guys can do, you would need some serious fabrication and custom adaptors to get a 2ZZ head to mate to a 1ZZ block, or any other block for that matter. you have to worry about clearances, oil passages lining up properly, etc. If it was sucessfuly done, I would've heard about it in the forums by now. And even if you could do it, you would have to change things so much that it would pretty much be pointless by the time you're done.

You can take a 1ZZ crank, and use it in the 2ZZ block to stroke the motor, that's sort of a hybrid setup, but you just can't piece together toyota engines like you can with other engine makes.

^^^ All very well put

after seeing the alltrac with a v8 twin turbo i think just about anything is possiable.

frankenstein motor? for toyota? if you wanna copy honda's frankenstein motor of the type s/r head and b20 base wouldnt using the Rav4 base with GTS head be more effective?

LOL, i dont know what im talking about.

back from the dead!

hes lying.

plain and simple.

theres no way currently to matt a 2zz head to a 1zz block.

the best solution is to use the izz crank remove the oil squirters and make it a stroker, with the 1zz bottom end. but no way is there (and you'd have to ask why the hell you'd want to put a 2zz head on a 1zz or even a 5fe)
