Spec C Hatch
So it begins, engine delivered to the master engine builder Mr Paul Finch today. Can't wait for this to be finished, a nice 500 bhp fast road/track car

Fully forged Raggy, don't want any failures. I'm looking to build a good solid fast car that will run well within its limits. The reason I'm doing this with no expense spared is if and when I sell it I can have no worries that who ever is lucky enough to own this amazing car will have peace of mind. I don't want to run 450 on a standard engine and worry that it might give up the ghost at anytime. I know these engines can run good power standard but I want it right with no surprises. Once the engine side of this project is complete it will off to Chevronmotorsport to get the handling even better than it is already.

Tbh standard, I know they are not the greatest for big power but I want to map it on the standard ecu and not use syvecs . If there's another way I'd be grateful for the advice.

I was going to use the standard heads, but have decided to go for the big port route. Last thing I wanted to do was build the engine and then wished I had gone the whole-hog.
I have gone for all the RCM bits and a arrow billet crank to.
Heads are being built as we speak to a fast road/track day spec, don't want idling issues. The overall objective is a reliable 550-600, but not sure if 600 will be possible as I've gone for the special Chevron TMIC.

Cosworth stuff in general is over priced, the issue with the hatch heads is that the exhaust port is quite narrow so at some point will become restrictive. Me personally regardless of big port or small castings would go single avcs get them ported, some 272 cams, single piece valves with retainers and valve springs and adjustable pulleys on the exhaust side. This will future proof your heads for over 650bhp

Had Paul Finch build me an engine and was running it in as per then had an offer I couldn't refuse for the Spec C . So moved on to the blue one, for now just Miltek, fuel pump, panel filter a map and a Chevronmotorsport fast road set up.

Chevron supplied me with a genuine Walbro fuel pump specifically designed for the hatch, I'm not sure if many other places have them
