Thanks both!

Apologies should have said, Duratec, 2.0 in a 420R

Happy New Year! Does anyone know the length of the bolts used to fix RBTBs to the head? Or do they use studs, clearance to the roller barrels seems very tight to get a bolt through the hole that's long enough to secure it properly?

I have a 2016 420R, has never stalled, idles fine when cold. I bought second-hand, so maybe its a new engine thing and just needs a few miles on it?

Thanks much appreciated

Looking for a standard throttle set up, thx!

Thanks John, I managed to find that one online, as a novice its not easy to decipher, just lots of random letters and numbers with no key!

Hi All I wondered if anyone had a wiring diagram available? Kind regards David

Brands also fine with standard exhaust

Looks fab but way over my budget. I can get a mx5 5 speed for £300 but as you say would be at 10 degrees tilt. Its for a mk1 Escort rebuild, to mate to a 2.5 Duratec. Is tempting though...

Hi All Anyone have a Caterham 5 speed (based on MX5 I believe) for sale? Thanks David

Thanks!

Long shot but does anyone have or know of a secondhand duratec engine for sale, any spec eg 360/420, 2.3?

Anyone tried to fit a Rotrex supercharger to a 420R, TTS sell a kit for a 2.0L Duratec for about £3k?

Hi All My first year of trackday driving my 2016 420R SV and I'm wondering about gear selection. I seem to spend most of the time between 4k and 6k revs. Is that too low, I'm not chasing /100ths just curious if I'm generally using the wrong gears! The engine noise doesn't really encourage higher revs, at 6k it's already v loud and I find I change up due to mechanical sympathy but maybe I need some ear plugs? Per google, torque curve is pretty flat and (hence) power curve fairly straight, so not sure I would be going any quicker. Have another trackday next Monday (Brands) so will give it a go at higher revs but good to hear your own experiences. Thanks David
