I'm in the process of designing a 2.2 stroker motor for a 'Four, and have made some part choices already. I'm hoping to start building the engine early (Q1) next year, so this is really just the R&D/planning stage. What I've chosen for the internals so far is as follows;

JUN custom stroker kit (Pistons & 17Kg crank. PN 1029M-T001)
JE Forged pistons @ 86mm bore for 3SGTE (PN 298701)
Eagle forged H-Beam 138mm rods (PN CRS5428T3D)

My question about these is whether or not the JE pistons will work with the rods and crank that I've chosen. I read somewhere (on alltrac.net I believe) not too long ago that the pistons supplied with stroker kits are actually stroker pistons, with the wrist pin slightly higher in the piston so that it doesn't extend past the deck on the block and crash into the valves. I'd like to have the option of using the JE pistons instead of the JUN kit supplied Cosworth ones, then sell whichever set I don't use - but are the JE pistons manufactured to accommodate a stroker crank?

As far as the rest of the parts go, I'm not sure yet, still need to think about what I'm going to use in the head - High lift cams, valves, springs etc. And I haven't really thought about what manifold I'm going to use yet either, although I know what turbo I'd like to use at this point.

The engine will be going in a weekend drive/trackday car. I'd like to start off hitting 400hp after the rebuild and then work from there, getting as much power as I can out of it for a track map.

Any thoughts and advice would be greatly appreciated smile.gif

Okay, all great info so far but what if I told you that 5SFE engines weren't that easy to get hold of around here? Neither are 3S-GTE's tbh. The local "breakers yard" that someone mentioned is the only one in this part of the country and it doesn't generally have a lot of 90's Toyotas kicking around.

Please remember that you could fit Nothern Ireland into California about 30 times and still have a good amount of land left over... This build won't be as easy for me over here as it might if I lived in the CONUS kindasad.gif

Most of the stuff I'm putting in it will probably have to be imported, and even the Engine might have to come over from England or elsewhere on the mainland. I'm not trying to make NI sound like some speck of sand in the Irish sea or anything, it's just that when it comes to building a high performance early 90's Toyota engine, you come across a distinct lack of engine and parts sources rolleyes.gif
