thanks

If your going N/A do you really need a cossie bottom end

i might 1 day lol... im just wonderin if a cossie crank would be more reliable and better off with 1

No real benefit for NA with the cossie crank but a must for turbo motors

oh okay sweet.. well if i brake a crank ill blame u 2 lol

I aint no cossie expert, but I would have thought that given the revs you'd want to run an N/A cossie too, the steel crank and steel rods would be worth having.

On the other hand, I would have thought that pinto rods and crank would be fine for a low revving (7500rpm, i.e not Phil spec :) ) cossie turbo.

I'd always understood that a pinto crank was not too bad. Vizard used to claim this. Rods arent flash however, but would still have an easier life in a stock cossie turbo that hard revving N/A version.

If money was an issue, I'd go with a pinto crank but better rods (injection even) if building an N/A cossie.

Ash.

Im building an N/A Cossie now. Iguess it depends what you thinking o doing with the car. I using 205 block but pinto internals for street.
Should be good for 7500 rpm.
It not cheap and parts are difficult to find.
Hope it goes well.

yeh ide love some strong internals but we'll c what haoppins i spose lol c how much coin i got..
thanks guys

The SG iron pinto crank is okay for 7500RPM - I did 8500 for a while, but was not making power that high so quit revving that hard, and ayhow it is the acceleration/deacceleration of the piston that gives the highest loads over the power stroke from N/A Cossie...In Summary less RPM is better.
You need forged rods and pistons, go for a long rod, short piston as it will reduce the rod angle and forces on the cylinder wall...Many people's recommendation...I had 2x N/A cossie motors over 8 years and they sound mad as hell on twin webers, but really in the end the bog stock cossie turbo makes enough power to launch a small ford 0-100 in sub 4 secs and make 360hp atw all day every day and uses less fuel (not that fuel economy means anything for a weekend warrior)...I have never had bigger grins. Phil will remember soon when his car is back on the road...I might just have to visit you mate to remind you of how nuts it is...[%]
