A longer rod is placed at a lesser angle so it is less likely to bend or be stressed. A shorter rod is placed at sharper angles and is more likely to bend but it gives a mechanical advantage producing more torque. Rod length also effects the speed of the piston at different parts of the stroke. It's a bunch of craziness generally tho shorter rods are better for low end power longer rods are better for high rpm poweri always thought short rods were good for turning a bazillion RPMS, like a honda..and long rods were for torque, like in a diesel..

I've tried the egr port just in-case you're thinking about using it. It will show no higher than about 450 to 500° when stepping on it hard, when actually whats coming out of the cylinders ahead of the turbo in the flow of exhaust is more like 1200° or so!
thanks. I figured out the reason the timing felt so off. On my old 1.6 i never pulled the cold start lever unless it was really cold. on this motor it has to pulled out on every start up until its warm or it idles rough and lots of light grey smoke. I took it to a dyno day at a local shop for its maiden voyage and with a little extra fuel it made 77hp and 142 ft-lbs on a mustang dyno. Then it proceeded to roast my new stock clutch on the way home driving like an @$$hole. I couldnt be happier coming from a 1.6NA with a turbo bolted onto the back of it. The EGTs read really high on this turbo compared to the K24 on the 1.6 would there be an issue swapping to the larger turbo with this pump?Also what is the proper proceedure for hooking up the cold start valve at the back of the pump. This pump has alot more available motion (lever can pull out much further from the dash). How do you know what is the proper postion?
