Default 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'd put aftermarket ecu in Darren I'm kicking myself I didn't first day could be forced down that road in next few weeks
The standard heads will be fine at 500 bhp

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.

Did you look at cosworth heads or is it cheaper to build the jdm heads to the same spec ?

Cosworth heads are made for the 2.5 I couldn't find any offering for the 2.0l.

You're probably better of speaking to the likes of Banny who has done this a few times or a few of the other members in the projects area.

IMO the Cosworth heads are over rated, particuarly when you take into account the fact you will most likely wait at least 6mths for delivery...........

various people including ourselves can offer something far more tailored and specific to suit the individual build

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

Its not that I would run it, the dual avcs have narrow exhaust ports and there is not much room to port them. Eventually that will restrict your flow and limit your power output.

Can this set up still be mapped on a standard ECU or will I need the wiring up rated and mapped on Syvecs?

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.

That's very similar to the mods I did. Pefect if you like your car very quiet. If theres one thing I would change, it would be the Milltek. No issue with quality/fitment & zero drone, but it is more or less silent unless you're really pushing on.
Chevron supplied me with a genuine Walbro fuel pump specifically designed for the hatch, I'm not sure if many other places have them
