SR20 in an MSP...

the IS300 has a bad bottom end but the block is that of the 2jzgte engine.

internals are whats holding it back. supra swaps on those cars (as far as motor swaps are concerned) are actually the easiest for that vehicle and amazing when done.

theres also a guy who dropped a GS450 v8 into the IS300 he had. Amazing to read it documented.

My roommate has an IS300 which is why I researched them :p . As far as rotary swaps? One of the techs @ my dealership actually has a B2200 pickup with a B12a rotary swap. Pretty funny car to check out. I didnt believe him until I saw it.

SO technically then, you could have an IS300 stock block, order Supra-spec forged rods and crank, stronger head studs, and have yourself the equivalent of a 2JZ-GTE ready for a turbo/supercharger? That would rock, because then you could keep the VVTi, which the Supra TT never had... (thumb)
 
Wow, I guess you could...

I just checked the specs and they are both the identically same block with 2997 cc displacement and the same 3.39 x 3.39 bore/stroke. The 2JZ-GTE just had 8.5:1 compression pistons where the IS300 has 10.5:1 compression pistons.

Hmmm, I think I've decided on my next car should anything happen to the ol' MSP...

I've been reading about supras because I will be buying one soon and I found out that to lower your compression you can install a 3mm headgasket and that seems to lower it enough to save your internals on higher boost. The 2jz has got to be the best production engine ever!

Installing a 3mm headgasket will lower compression on pretty much any engine. The issue is that the 2JZ already had low compression and rock-solid internals, whereas the IS300 had 10.5:1 compression pistons which were weak and so were the connecting rods.

My point was that if I had an IS300, I could basically pop in a 2JZ crank, connecting rods, and pistons, and I'd basically have a 2JZ with VVTi, something the Supra TT never had. All with lower insurance cost in a more practical 4-door package with a smooth ride and luxury features.

yeah but the head on the IS300 is completely different. shortblock = identical though (not counting internals).

Wouldn't that be an advantage though? The VVTi presents some additional tuning capabilities that the Supra TT never had. With stronger head studs and engine management along with 2JZ internals, the tuning potential of the hybrid engine is greater than that of the 1998 2JZ engine...

Since this is a Mazda forum interested parties should probably research here.....http://my.is/forums/ ......now back on topic.

I think it would be cool/different. I miss my old SR, but if money is no option and you want to be different/first I would slap the MS3 motor in it
 
wow, wish i could've gotten on here earlier, i dont give a flying s*** about the is300 or the supra swap, or i wouldve posted on some other toyota forum about it...if a mod could possibly edit the thread that'd be sweet....but anyway...

stand alone would be awesome, should've thought of that, that would help out alot lol. i found an awesome shop locally that would make some beefy axles for me that they say will withstand nearly 400 lb ft of torque. that would definitley do well enough haha. i also got a longblock sr20det from a buddy thats in good condition when he pulled it out.
 
seems like you are really going for it...
just try to keep it as simple as possible and take lots and lots of pictures

i'm all for changing the heart of a MSP as long is for the benefit of it and it sounds like a sr20det should do the trick.

good lukc on your venture dude...and keep us posted

and somene should delete all thos threads regarding the supra's ..who gives a **** about them anyways, they got their own forums...clean this thread, it looks promising

haha thanks thats the inspiration i wanna hear!!! lol...it might end up coming down to keeping the msp as a DD though, and just buying a base stock protege to do the swap. either way i wanna get it done. and fast, but prob won't fully be starting til mid summer it looks like.

what motor is that?
Click to expand...
turbo MR2 and Celica and sometimes can pump out 800hp. Now I couldn't imagine 800hp in a FWD! I think it'd be like driving on bare rims on a frozen lake, except having to change tires every week!

few mins after that i knew the answer
the power of GOOGLE!

800 hp, damn...thats something to look up to
 
beh nowadays any motor can be forged to handle that level. just costs money. 3sgte is nice though but big power is nothing now a days, just takes big wallet, nothing really impressive about it. Im more impressed by its capability to handle something like ~400whp stock.
