I own a sw20 currently have a gen 3 swap, and I just purchase a caldina gen4 short block (headgasket came with it)from rpmgarage, plan on being 100 octane, this is a track car.how good is the short block going to hold, I know a few people say that the rods are thinner, same as beams (same part number), but I did see one make 394whp 22psi 100octane, with just bolt ons, who else on there celica has good succes with there 4th gen engine. here are my specs,http://rides.turbomagazine.com/ride/1013953/deseroner/1991/toyota/mr2/index.html
the reason I went with this block high compression, stronger block currently have gen3 97 block not the revised around the water pump.

anyone .

what is your question?

who has good success with there gen4 block, who has a highpower one. I am also upgrading to st246 pistons with eagle rods.

the 4th gen blocks are very strong capable of handling good amoutnts of HP stock. they are just about identical to the other gen blocks and even the 5s block. ive been told (and seen) the blocks handle in upwards of 600hp but of course other mods were made.

ok so what I am going to do is use st246 pistons with eagle rods. I am going to use it for time attack.

your biggest limitation with the mr2 platform IMO will be intercooling.
keep that in check, (provided your tune is adequate of course) and you shouldnt have any problems.
one of the reasons i think the 3s in the celica vs the mr2 mod for mod tends to make more power is because we tend to run good size front mounts, or the water to air intercooler in the case of the 3rd gens.
good luck with your build!

got the big intercooler setup in the trunk.

is that the KU manifold?

well fellas I ended going 5sfe crank machine for 3s rods using acl bearings standard , eagle rods with cp stroker pistons 9.0:1 , apexi gen 3 head gasket 1.1mm on my gen 4 block, should be bullet proof , who ever wants to just bore there stock gen 4 caldina block with st246 pistons I will sell them, they are oversized 0.5mm so 86.5 , can use on stock rods , just have to bore block .5.
