whats the difference in the cams????

[doojo0014]

im on bisimoto.com and ive been checking out the cam shafts. i plan on turboing the car when income taxes come. their are the same priced cams

229$
one is level 1 regrind offers 10% improvment
#2 is 1.2 turbo
#3 is level 2 regrind offers 15% improvenmt
they are all the same price but the level 2 reccomands to up grade the cam gear and springs

y are they all the same price but offer better outputs???
am i missing something here.

this is the next thing i'd like to install, but wanting to make sure im not getting ahead of my self.

is their anything i need to no befor i get styarted??

The cams cost no more to make, regardless of the grind, and Bisimoto isn't out to take advantage of the tuner market.

The Stage 1 and Stage 2 grinds are made for NA applications, whereas the turbo grind is made for turbo applications. The NA grinds have more valve overlap, which is good for NA, but bad for turbo. The Stage 1 cam doesn't require a valvetrain upgrade, whereas a valvetrain upgrade is STRONGLY recommended with the Stage 2.

Was it not said recently, either by Jose or Wikked, that stg 1 cams usually outperform f/i cams?

Thanks Mike. I could not have said it better myself.

So would a Stage 2 cam actually harm the engine if I used it without supporting mods/a built engine? I want to get something that will give me good numbers with a DSM turbo build on low boost before building the engine but I'm going to build the engine eventually. Would I be better off just getting a Stage 1.2 and then later building the engine or getting a Stage 2 from the start?

We'll need more information to properly guide you here. What are "good numbers"? What is "low boost"? When do you plan to build the motor? What is your budget for the DSM turbo setup? What will be your budget for the motor build? What are your power goals for the motor build?

This kind of information is very relevant to how you should proceed. If "good numbers" means 150whp, and "low boost" means 5psi, that's very different than 200whp @ 4psi, or 200whp @ 15psi.

If you only have enough money to scrimp together the DSM setup and no money left over for a tune, you'd be better off tuning on a stock cam (f22a6 hopefully) than trying to run a FM hack and buying a cam.

As far as buying a cam from a respected shop that highly recommends running upgraded cam gear and springs: they know what they're talking about. They wouldn't suggest you do it for no reason. I do not know what damage it would do to your engine (maybe none, maybe you just won't realize the power benefits of the cam without the additional parts). If you trust the company enough to buy their product which they tell you is good, you might want to trust the company to know how their product should be installed.

A cam designed for NA will be detrimental to a turbo engine. The overlap will cause you to blow the intake charge right out the exhaust valves.

Fantastic advice right there!

Yes, any cam with high lift and duration can cause problems with old, tired valvesprings. Especially at higher RPM.

As for the FM hack.. the good thing is that most kids these days aren't even aware of that oldschool method! At least not around here. A chipped P06 is the standard... the only noob mistake that people seem to make with that is running on a basemap, and not a real tune.

The Bisimoto stage 2 camshaft will only require, heavy duty valves springs like the Bisimoto valves springs. You don't need a fully built engine. Adjustable cam gears would be recommended to properly dial in your cam. You can use the Bisimoto stage 1.2 without turbo, but it will not provide you with full potential until you finally install a turbo. But the added power will be noticeable.
