There's no need for strengthened (ie aftermarket) rods or high compression pistons. I'm guessing they were building a high compression NA VQ37 hence the use of those parts.

Jun's answer all but tells you they've never (successfully) run them on a stock engine.

You can order the springs directly from jun. several of the other components (o rings, etc) are consumables are will need to be ordered.

ok guys seems that ill go ahead with this after all talked to my install guy and he told me that he can install them no problem, just wanted me to ask jun if i can reuse the oem springs or need aftermarket ones, please help me choose the nessasary parts that jun provided us in its list, as soon as i get that answer ill be orderingf them straight away. and also can the car be driven without a tune with these cams?

you should get a tune to get all you can out of the cam!

i iwll be getting an uprev tune ofcourse, but would it damage the car if i drove it for a bit without one.

I really hope you go through with this. im excited!

I believe this would depend upon how aggressive the cams are compared to stock ones. Since I am not well versed on cams, I won't even hazard guess if these are safe to run without a tune or anything else.

I think the aggressiveness is mild 370tune guys where r u I wanna order these from u loool

Keep us posted man. Your my hero!!! LOL

called 370tune and i dont think they are open yet

don't forget to take pics of install, zuperman

JUst heard from 370z tune looks like ill order them after all :D just waiting to hear with regards to the springs any1?

Neat.

Be sure to get a dyno just before you have the work done for a baseline to compare and contrast :tup:

^^ very important!
