Yeah, the Unigroup cams. You also use the standard buckets, you will need to relieve the head for the lobe and you will need a decent valve spring. Camtech do a spring and Titanium retainer package which is very reasonably priced and will do the job.
The cams are a little pricey BUT you don't have the expense of buying different buckets like you would if you were to run say a Tomei Procam, so it pretty much works out same same.
I do own a 33 GTR.
Fuel system is 2000 cc Injectors, 2 x 044 feed, one 044 lift, 5 litre surge tank.
As for the Poncam's, I believe the 250 "Type R" would be a better cam than the 260. Same lift, less overlap. PM XKALABA about his thoughts of the 250 vs 260. He ripped his 260's out.
