Cosworth head
Complete Cosworth head
Seems like a good deal at 'buy it now' £300...
realtively easy conversion for a Pinto
(just wish i had the £300 spare!)

I have been thinking about putting one of these on my pinto. Anyone know how much power can be had from this conversion?
Cheers

Have you got the 205 block?
I think you will possibly have to look at rods, pistons and crank change as well.
I might be talking total b00locks of course.
It wouldn't be the first time.
Experience is what you get when you don't get what you want!!!

Yes I have, and I understand that the above will apply for revving over about 7500 rpm but I was wondering what could be achieved up to that limit
really.
Alternatively is it better to to just go and get a vauxhall?

according to des hammils bookj the rods and crank and pistons are fine up to 7500 rpm....
you need a new crank pulley and some other odds and sods.
should easily give 200bhp with twin 45s or throttle bodies... 
almost forgot - you get to put a 'Cosworth' badge on the back of the car that has to be worth
another 10Bhp..... errr

I believe natasp ybhead/205 block can ultimately make 280-300bhp on pump fuel, pretty much the same as a vauxhall imho.
the difference lies in what bits you already have that'll save you money and what bits you'll need. Higher power figures will require more
revs and hence rods/crank etc... and the power will be higher up the rev range typically. You'd need different cams for natasp and I believe the
heads benefit a lot from porting work as turbos don't need the porting to get the flow. A chat to burtons or a decent engine builder would be my
advice, its a pretty common conversion but I'm no expert by any means.

I have his book and very good it is too, he's not too specific about power outputs though as I recall.

No.Good motor though.Older design than a Zetec(?).More expensive than a zetec.Now hard to get hold of than a zetec.Cost more money to get Vx to type
9...Can you see where this is going.
And nope.It's still not anywhere near finished.And no you can't have the spare...
..Which was nice..

For my sins I once put a cosworth head on a pinto, they need a lot of port work too make them work but it can be done (loads needs too come off inlet
too match them up too inlet manifold let alone flow), cam pulleys are same as CVH if i recall so if you want a vernier pay CVH price rather than
cosworth price, crank pulleys are cheap enough, you also need too get the compression ratio up too. Best I saw on rollers was 180ish at wheels, that
was steel rods, re ground cams and 48's.

Shhhhhhhhhhhhhhhh!!!!!!!!!!!!!!!
You'll get me shot!!
And I don't think I want a zetec, I want something which will give me 250 BHP or more......

Jon, 180 at the wheels - with 48's etc. that sounds as if it had a lot of work.
I get 150 at the wheels now so I'm not sure that would be worth it.
I might just go back to plan B(variation iii, subsection 2 - honda s2000)

Would be easier that route, I only did it as i was all but given the head and I already had a "steel" bottom end on the pinto, IMO its
defo easier and most prob cheaper too get a VX16v up too that power than a atmo cosworth. The VX engine is a very good one too go for.
