F4R proven tuning spec list please

[Rorygillies7]

This is my first post and I apologise if it is a question asked 10000 times. I’m currently a 182 owner.

However I am looking for help to spec a F4R build. I’m very likely to use K-tec itbs but apart from that I’m wondering about which camshafts would be best. And if arp bolts, head gasket etc are essential?

It is going in a conversion which I’m likely to get lynched for if I name😑

Thanks for any help.

you'd be fucked if you built an engine without a headgasket!!

 

[Rorygillies7]

I worded that fairly crap. Was more meaning a better quality gasket than OE

Oe gasket is a steel item and are actually very good tbf mate

+1 for pure.

Don't need arp.

OE bolts, head gasket ect.

What power do you want. I have itbs in a race car and have over 200hp at the front wheels.

Thanks for the info. Around 200 @ fly would be ideal for budget as it’s going in a 700 kg shell. Take it your race car is high spec?

Don't need arp.

seen 4 engines with a rod bolt go, for the sake of scrimping on a £100 set of bolts compared to destroying a complete build it's a no brainer.

I’ve been running a ktec built engine for 8 years now with their itb’s never had a problem with it apart from new injectors. Basically built to oe spec but with 84mm high compression pistons and rods...also got arp bolts for piece of mind and 182 manifold.
Pretty standard head/cams with uprated valve springs.. 201bhp 165ftlb.
Mk2 golf rad.
If I was doing it again I’d be going for the pure motorsport Itb setup and their radiator.

Got new cam belt etc next week and schrick cams going in. Can tell you the results of them, then.

Thanks! Good to know. After the recommendations I’ll probably go with the PMS itb’s. Had abit of a look about for pistons online. I’ll probably go for a very similar spec. If you keep me updated about cams that would be appreciated.

Yes it is.

I give you some details.

Pure motor sport headers, ported head, exhaust.
Supertech double valve springs, titanium retainers and valves. Head assembled by pure.

Jenvey throttle bodies.

Wossner pistons 11:1 with pec rods. I'd go for the pure ones if I'd do It again.

Cat cams Cam and Cam adjuster.

Running e85 with a emtron after market engine management system.


I have found at this power level the weak point of the Clio has been front drive shaft. (have 2 gearboxes, one welded diff, one quaiffe) and gear shift forks as the plastic ends can't handle the load, fall off then you break syncros followed by gears.

If using on high load tracks with light weight car a must is upgrading rear disk and hubs (pure have a kit) unless you like loosing a rear wheel and hub on track. Which can be very nasty from experience.

Highly recommended the ktr 750 club suspension (spax)

Mk2 radiator is great with itbs as Clio one gets in the way.

Thanks! Wasn’t expecting so much help. Regarding suspension an rear hubs I will keep that in mind for my 182. However this is going in a nova. Sorry if that offends anyone

Any particular reason you’re not using an XE engine?

It’s very hard to find good coscast ones nowadays that aren’t stupid money. I’ve never been a big fan of them anyways plus F4R’s are newer and probably better on a lower budget in my opinion.

I think k20 lump would be my first choice.
