Okay so I have completely stock long block. I want to put skunk2 pro 1 cams in it. Do you think my v2v and p2v clearance will be alright or should I check those while I'm at it? Also I dont rev my car past the factory revlimiter and I hardly touch the revlimiter... Do you think I will really need a valvetrain upgrade? Thanks.

This is my first post I'm sure I will get flamed for something but whatever.

 

Shims, lol.

Yes, you will need to upgrade your VT unless you want to destroy your engine.

 

Im not one to run the hell out of my motor everytime I drive it. Do you really need valvetrain upgrade if your not reving past 8k. I don't know if it will float the valves or not though with that cam.

 

Go read Skunk's website and see what they say is required for those cams, then you'll know for sure, right? With performance cams, they always make power past the stock rev limit so you'll need to exceed it to really benefit from the change. You will also need a tuning system like Neptune or Hondata etc, adjustable cam gears if you want them to run right.

 

hey, are the pro cams oem?

Then no, run a valvetrain designed for those cams. Simple concept.. run oem cams with oem valvetrain.. broski

 

Good, so you don't beat on your car.

Lol, what does the rev limit have to do with a spring not being able to control a valve at a certain amount of lift?

Finally, while you don't know whether you need a complete VT to run Pro Series cams, I do. Please talk with any reputable engine builder or tuner better yet call Skunk2 like 00Red_SiR posted, I promise you they will tell you it is mandatory to upgrade the VT for those cams.

 

Alright thanks for the help.

 

So why get Pro Series cams?

 

I'd say run em Pro1 cams with stock VT and report back with Pics

 

Skunk2 Tuner stage 1's are the only cam I'd consider running if I were him but he'd still need tuning.

 

i would put a set of valve springs retainers and ditch those pro1s stock compression just doesnt combine together go with stage 1's or ITR cams theres no point using PRO cams for a stock compression GS-R engine.

 

Ahh not necessarily true. I've seen and tuned stock compression GSRs with Pro1s that made pretty good power.

 

Yeah and im sure they have valve springs and retainers lol.

 

Again

i repeat..

CR is 1/10th the setup for using cams.. and building a motor..
Why do you think People who have the supporting mods can RUN huge cams and makes globs of power.

I've seen stock b16a2's gain over 13WHP on a stock motor with these cams.. Hell i've tuned tons of little b16's running huge *** cams.. they make power.... BONE STOCK..seriously dude???

Stop posting **** inreguards to compression ratio.

 

Calm down people ask for opinions of course your going to get a million diffrent ****ing answers.The guy stated running stock valve springs and retainers you going to defend him on that to? Yeah stating they make decent power when you could go with diffrent cams for that setup its flat out common sence.Idc how many cars you tuned every persons a diffrent tuner everyone has there own opinions.But im sure your one of those guys that doesnt listen to anyone and knows it all right?HA you make me laugh.

 

I plan on upgrading my valvetrain when I do decide on a cam.

 

If you want cams you can drop into a stock GSR motor with stock valve springs and run without real tuning, you only have a few options. These aren't all of them, but this is a good overview.

1) ITR or CTR cams. They are an improvement over GSR cams, but not by much and usually cost more than some of the aftermarket cams that make more power.

2) Skunk2 stage 1 (tuner NOT pro). These are really just a slightly more aggressive version of the ITR cams and would be a good fit for your motor.

3) Buddy Club 3+. Personally, these are the cams I would go with in your situation. They will make more power throughout the entire powerband and are especially strong in the mid-range, which makes them great for street cars.

4) Blox/OBX/etc - there are copies of the better brand 'stage 1' cams available, but its hard to get solid info on either the specs or the build quality on some of them.

That said - you really should upgrade your springs if you are going to cam your motor. Its not hard to do and it is not only safer, it gives you many more options for cam selection.

Best of luck with your project.

 

I think you can't read..
So to correct your first statement

Secondly, i've been in the "game" for alot longer then most on this board, i've experinced more and see what works and what doesn't..
Then i've seen what really matters in motor setups, specially all motor ones, and what does not.
I'm saving people the trouble. I've seen you not once but twice so far in two different threads, talk about compression.. Do you even know what that is, and how little of a part it actually plays in making , Serious power? Its considered a big part, when your streching the limits of pump gas.. But pump gas limits aren't reached until 13.0CR's..
Do i think i know alot, ya i do.. infact i believe i know quiet a fair amount..I make you laugh?

I'll tell you what makes me laugh, the fact that children, pass on advice on this forum, when there is thousands of dollars on the line.

 

Do you actually read threads before you make inane posts?

Where in this thread or any thread have you seen me or All Motor post it is ok to use a OEM VT with Pro series cams. If you had read any of my previous posts in this thread you would see exactly what I told the OP not to do.

Ahh no, what the "guy" stated is below. Read the bold so you understand what the "guy" posted.

Here's the intepertation since reading comprehension is not your strong suit.

I wrote stock compression not stock VT.

This forum is littered with non-sense because people with little to any experience building engines or tuning post answers that they know little reasoning behind like this gem.

Really, how did you come to that assessment, years of testing?

BTW, you it's spelled sense not sence.

 

Gawd.. marc is like.. the snake hiding in the bush waiting...



I'm not a dick btw, and neither is anyone on here, who actually knows wtf is going on.
We're trying to help you guys, this is a world WIDE forum

You realize the stupid advice you give someone, could be used by some moron who doesn't know better across the sea.. and he blows upa 5k motor because of what you said..

Get it right folks


IF IT IS NOT A OEM CAM YOU CAN NOTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT

GET AWAY WITH RUNNING A OEM VALVETRAIN.

Sooner or later your keeper will fail, sooner or later you will float a valve and sooner or later, you'll be crying in a corner cursing the nignog who told you to run stage 8 cams on oem valvetrain.

 

So, true yet so elusive for some.

 

I'll steal a quote from donf to look smart

building a motor is mostly and should be centered around r/s ratio and mean piston speed..

Then look at the power output that can be made a safe level while retaining relaibity.

 

Thanks for all the help guys. I didnt mean to start arguments

 

You didn't. Everyone here is always throwing chairs and acting all Jerry Springer.

 

its not your fault im fairly new to the site myself and you gotta learn to pick and choose whats right ive done a ton of reading befor making my choice on any part selection... then done more reading and decided to switch that part anyway... i guess what im tryna say is read alot more on the site befor making your cam choice listen and take into consideration what ALL MOTOR and mar778c are sayin they are both smart and wouldnt steer you in the wrong direction
