I'm curious to hear what kind of numbers are being put down.

They're supposed to be longer, right? It's a stroker kit... Longer rods with the appropriately larger crankshaft gives longer stroke length than stock.LittleRocket said:I have the n/a kit for a customer build. They look like bike pistons. The crower rods are LONGER than stock 2zz rods.
The build is coming along slowly but we will have pics and dyno when the time comes.
A Haltech will work just fine wuth this.sleepless said:Any updates? Does anyone have a custom ECU that will take advantage of a stroker and other goodies one might put on such a motor (cams, header, etc.)???
Forgive me, for not following up. The assumption about shorter rods, requires the stock crankshaft. If you have an appropriately re-designed crank shaft, the rods are not necessarilly shorter, correct? I believe, the MWR kit includes a crank, though if it's just a stock one, I'm not sure why.LittleRocket said:Normally stroker rods are shorter because the stroke of a stroker is longer. The longer stroke with stock rods and pistons make the pistons shoot up above the deck. This are bad.But the MWR pistons move the pin way up into the piston and allow for longer rods and longer stroke.
The Dartons are a simple standard sleeve. The machine work isn't cheap but there's nothing too tricky about it. We do it because the stock walls (aluminum with coating) don't hold up well with forged pistons.turbo2nr said:Darton sleeves. That's nice, but expensive machine work. I see our motors have a fully open deck:huh: . That's weak garbage. I have blown up plenty of Subaru motors with semi-closed deck blocks. I now run a EJ22 fully closed deck block. Moving cylinder walls sucks.
I wonder if the Darton sleeves need dowel pins to locate them? Anybody seen that type of stuff? The whole block gets hollowed out almost, pins gets machined verticaly around the floating iron sleeve. Expensive and very hard machine work. I'd just buy some block-fill and pour that in. :nanner:
