Question is about my VR4, but I've put it under 2g because of the engine. I can't decide on cams. I've read a ton about both of them, but I keep changing my mind on which to get. The choices are GSC S1 or Kelford 272.
The engine they are going in is as follows
6 bolt 94mm stroker, 8.6 comp (I'm planning on E85 but it's not available everywhere), BC H-beams +625 bolts. Manley HD pistons, CNC ported 2g head with +1 valves, 80lbs beehives, Ti retainers, evo 3 intake.
Due to budget initially exhaust is ported evo 3 mani, ported evo 3 turbine with 20g compressor, 3" dump to 3" RalliArt exhaust.
Once money allows (at least a year) I'm planning on a small runner divided T3 manifold to a 56mm comp HX35 with 12cm twin scroll turbine running 30 psi on E85. I might get a JMF Street manifold at this point too.
Car is for highway and caning in mountains, but will see some traffic.
With the hx35, the 272s are a no brainer. I guess I'm worried about over camming while I still have the TD05 and end up hating it, or should I not worry because either way it's going to be better than my worn out stock engine that has 7 inches vacuum at idle, .
