Thats mint Sam, Im struggling to even find stage 2/4 Peice UR kits for sale?!

And re Andy's ohh would of thought they had pulley manufactured with a collar pressed over the inside of the pulley.. mabey so but not correctly. A line of enquiry none the less.. being a proper firm. If one replaced the oil seal when fitting and a problem occurred would be in reason to send the crank pulley back to them for a refund as it failed to deliver.

UR themselfs only list a 2 Peice Crank/WP set too, ill be dammed if its discontinued.. cause that leaves me with Gspec there damn expensive or try



JGY set

Greg is your man

(off topic) I orderned some copper gaskets from SCE, after 2-3 weeks I thought they were lost. Asked Greg to get them for me, and they were delivered in within a week. Get all my stuff from him sr20 related. He 's the best.
 
Bugger though that was the case, otherwise choice would be obvious. Thing is I can get Gspec Crank/WP Pulley & a SR20 RR sump pan for same price as the UR two peice kit

Anyone any ideas why one is so much more expensive then the other?

Only thing that I can think of is the more expensive one is for the SR20DE thus not needing a spacer. Whereas the other one is made for VE engine but with $12 spacer the VE one still works out shitloads cheaper. Or am I missing some crucial here?
 
The UR crank pully is the best to have. It has a steel sleave where it sit inside the crank oil seal, otherwise the seal cuts into the soft alloy. Not sure if the Gspec ones have this design?

G Spec crank pulley incorporates the steel sleeve on the back where the seal rides to prevent grooving and leaking.

Also the waterpump pulley is the biggest on the market.

Ahh thats good news, do we need the DE waterpump to be underdriven anymore though with having a larger dia WP pulley

Cause its allready underdriven by the UR kit.. Guess one could say its inconvlusive as there isnt any tests on water flow rates that I know of on the Gspec pulley vs UR. Would just be another peice of mind bonus
 
I doubt there`s any flow data eddie. If you just run a new crank pully without changing the WP pully it will spin even faster becasue the crank pully is smaller in diameter than stock.
