friend of mine is parting out his lude, gives me his jdm cams for 40 bucks. Any fitment issues in a USDM H22A4? Do i need to change springs, valves, etc. or can i just drop them in with no problems?

btw the h22a4 is stock internally.

 

doing research found specs for US and JDM cams:


H22 US Spec
Int- 288 mid Exh-308 mid Advertised Duration
Int- 231 mid Exh-234 mid Duration @ .050"
Int- 448 mid Exh-415 mid Gross Lift w/1.55

H22 JDM Spec Type S
Int- 309 mid Exh-315
mid Int- 230 mid Exh-230
mid Int- 469 mid Exh-438 mid


any major difference in power? i know its better to go with something like crower stage 1 but if i can get these cheap i might as well use them for a while.

 

You first need to find out what kind of JDM cams you have...

JDM H22A cams are not Type S cams unless said they are Type S cams...

JDM H22A cams will bolt up no need to change valve springs or retainers cam doesn't have the much more lift.

Type S cams will require Type S valve springs at the least. Type S has more lift then JDM H22A cams which does require the upgrade in valve springs to be safe.

 

he just says theyre jdm i ask him and thats all he says....im just gonna forget the whole idea and go with crowler stage 1, crowler site says i dont need to change springs or anything....this true?

 

Yeah Crowers S1 will go straight in, not sure if i would bother to tell you the truth, couldnt be as lumpy as Type S cams and I dont rate teh Type S cam realy, spend your coin on decent headers then come back to cams :-)

 

yeah forget those cams, i gaurentee there not Type-S cams. if they were he wouldnt be stupid enough to sell them to you for $40.

 

type S cams have a blue tint to them.....do yours?

there is no such thing as crowler...its CROWER....

You MUST upgrade your valvetrain with a cam of bigger lift.

Yeah unless your motor's pretty modified why would u wanna change ur cams? All that would change is the lift duration on the valves which would hinder performance on a mildly stock engine. The type S cams are for the Type S motor because the compression ratio is different among some other things and that's why it needs slightly different cams.
