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

why are you overengineering this? just use a 5S-FE crank, grind the rod journals down to fit Eagle 3S-GTE rods. and i have wiseco pistons in my Stroked All-Trac

I'm sorry, I wasn't aware that I was overengineering it - I've read of people building 3S strokers with a 5S crank before, but I wasn't sure until recently that the 5S crank could handle the same power as a purpose machined, lightened stroker crank. What stroke distance would I achieve with a modified 5S crank then? And for the sake of being thorough, could you give me your input on the question of the JE pistons with the above anyway? So that I know all my options.

The 5S crank is forged, right? Where might I get one? You see I planned on building my engine with as many new parts as possible from the outset. Basically starting at zero miles on all the internals. That doesn't necessarily have to be the case, that's just how I'd planned it from the beginning.

The jun stuff is way overpriced.
Like smaay said, run a 5s crank and wiseco stroker pistons with the eagle rods.

Yes, I agree with you, it is overpriced, but I'm more than happy to pay a bit more to get good reliability and a strong engine capable of handling big numbers. I want to build it once, properly. If that means spending more to begin with, then sobeit.

Any particular advantage to running 1/2mm bigger bore on this setup? The cost of having anything machined to tight tolerances is very high here - I would have to send the engine components to England to get this sort of work done because I don't know of any engine shops in NI who do such work. This adds more cost to the build and if possible I'd like to avoid having to send stuff here there and everywhere to get work done. I don't even know where I'm going to have the head work done at the moment. Chances are that's going to be a big problem with my build when I get to it - I'd love some suggestions on good, reputable engine shops in the UK if anyone knows of any.
