OEM Pug parts 2.2 stroker !?

[wladimir031 8]

I was soldering my parts from garage and some measuring and thinking..

maybe this is cheapest combo for stroker for road car... lets see

 

Block: xu10j4rs 86mm

Crank: dw12 96mm (2.2hdi) 

Rod: xu10j2 152mm with 22mm small end

Pistons: xu10j4r because also use 22mm press fit pin 

 

measuring: 235 - 152 - 34 - 48 = 1mm 

1mm deck to piston clearence for chasing CR from 12 to 11:1 (you choise) ... hmm

with some cuted deeper valve reliefs and decked block by 0.5-1mm you have nice bottom end... with arp rods bolt i think is safe for 7000-7200 rpm

 

what do you tnink ?

pistons wont work as RFY (S16) use clips and are bushed rods, RFV/RFS are shrink fit non bushed, however if you get aftermarket pistons with larger cutouts they tend to use circlips.

mention XU10J4R (RFV) and XU10J2 piston rod combo... both are shrink fit 22mm pin...

A friend had this piston/rod combo with a 88mm crank on a turbo engine, 260-280hp and no problems.

He had a good aftermarket ECU (for the time) and the map was done by pros so the pistons probably didn't see much knock.
