3rd Gen 3S-GTE Stroker, Will my chosen Piston/Rod/Crank combination work? Options

[Unicorn]

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

the easy method:

Might be a good idea to sign up on www.mr2oc.com and research the stroker motors there
Also the over sizing of the piston, helps lead to a square (or even oversquare) setup, which reduces the side to side motion of the assembly (reducing heat, wear).

Ah yes, the easy method I've seen several different place selling RTB short blocks. None of them have been as reasonable as a little under £2K for a 2.3L stroker though. That's seriously tempting, but it'd cost a bit to get over here, and I wouldn't have the satisfaction of building the block myself

I was aware of the actual purpose of boring it out, but in this application (with a 90mm stroke) you're only getting a maximum of 1mm more (87mm) over the stock 86mm. I know every little helps but isn't it more effective if you're not stroking out the block?

Hi,

Hey Sunny, thanks for that link, I've seen those BC kits as well. Probably the best kit for what I want to do - much better value than the JUN stuff too! I just favoured the Eagle rods and JE pistons from several reccommendations.

You guys have already given me so much help and the thread has only been up for a few hours! That's why this place rocks
