5SGTE, what block to use?
Reply With Quotei suppose the different boost additive makes it hard for people to gauge what HP you'll easily make.
but 200kw out of a stock stroke 3s with ct20b turbo is child's play. have a look in the 3s dyno thread. think cut's made that on his relatively stock gen3 with ign upgrades. plenty on the mr2 forums get that, even on the gen2's with hiflowed or ct20b's and engine management.
with the added 200cc you should be able to get that easy.
the best way to do any stroker is to use the appropriate 5s sized rods and pistons. until recently it was only pauter that made them(but it's an off the shelf size so you can get them cheaper than their list price) but know i've ssen 5s rods on ebay...dunno how good they are tho.
the other way is to machine down the big ends to suit 3s rods, but you still need the 5S stroker pistons from CP as the crown height is lower in the 5s pistons obviously cause the crank stroke pushes the piston higher up the bore.....
also the 5s block has a bigger bore, if you go 3s block you'll still be limited to 86.5 bore, you can get 1mmOS piston's but then your making it easier for you to encounter the whole bore's cracking issue which is why people go the 5s block.
also you can have the pauter rods with oil relief grooves machined into the big end which supposedly squirt's the expended oil up under the pitons, still not as much as the 3s squirter's.
another thing, the CP piston's aren't custom, they have them as a listed size and cost the same as their 3s pistons
