I have afew questions and this seems the place to ask!

Been looking on the tube, and theres a Sierra and Capri (looks to be the same owner) thats producing 304bhp and 280bhp, this is what I'm after!

I have a full cosworth yb bottom end ready and waiting, but I need a final spec for the head to work too.

Firstly I know I'm going to need an unleaded injection head with hardend valve seats.

I'm thinking of making my own alloy inlet manifold, but I'm not sure how to go about choosing the rite injectors. To run this ill be using a mapable Omex managment ecu.

Uprated spray bar, I know the pinto has a problem with this blocking up, has anyone cured this problem and make an improved spray bar?

Both the Capri and Sierra on youtube both have ""close to standard heads" with the standard cam. Is this possible!? what cam do I want to be thinking about if one is needed, also what valves/springs/followers should I be considering.

Group A head gasket with arp bolts?

I intend to do abit of porting, polishing, and matching, but not on a major scale unless I'm going to need it to get 300bhp? I didnt intend on fitting bigger valves. Inlet I was going to remove all ruff casting, match the ports and finish in 80 gritt. Cambers and piston crowns I was going to polish like mad, and the same with the exhaust ports, matching them as well.

I have a Nissan 200SX turbo manifold and have cutt that up and had a friend tig a pinto flange on too that.

Lastly, what turbo works best? the Sierra and Capri on youtube both run a Holset turbo, I understand these are American and pritty heffty bits of kit? (tripple the price of a garrett)

Intercooler I have an alloy one from a 4x4 Sierra, will this surfice?

If anyones got any other advise I'ed very extremely grateful, thanks everyone.
