Mitsubishi 4g52 Tuning - Sourcing a Camshaft

[Hudzoyne]

I am building a tuned 4g52 for my 1978 Colt Sigma GE and its a massive struggle to get service parts over here for this engine let alone tuning parts so:

- I have had an exhaust flange cut so I can build a custom exhaust manifold
- Inlet manifold modified to take 38mm quad motorbike carburettors
- electric fuel pump from the bike the carbs were removed from
- Balance shaft eliminator kit from AUS ebay
- Having the head skimmed 3mm(This should bring the compression to around 9.5:1 on an astron 1 I believe)
- Electronic ignition kit
- Ported cylinder head
- 2.25 or 2.5" exhaust system with straight through silencers I havent decided on diameter yet

The thing I am struggling with is a performance cam, what would somebody recommend for this engine and where can I source one? I am finding it impossible to source one.

Does anybody know of any companies in the UK that do custom cam grinding at a reasonable cost?

I've had a quick look on some Aussie forums, and it looks like people generally get their original cams re-ground. Australian cam grinders do have grinds available for these engines though. You might want to do some research to see if it's worth swapping for the cam from the 4g54? I have no idea if they're any different or not, but it's worth a try.

Might be worth having a look around here:
