• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

I thought I would post some pics of my "dream car" I wanted one of these widetracks long berfore they even came out. I ended up buying my '95 GP 'cause my previous car wasn't goin to last 2 more years! Then, a mere 13 YEARS LATER, I gave up on my '95 (too many problems occuring). Then, by pure luck, I stumbled across this car.

My plans for the wheels...please disregard the paint scheme..I did 3 sec. after I finished it!!:D


 
Re: New to moddin, kinda new to site, long time gp lover

Yeah...it looked WAY better in my head...(thank God for photoshop!!)
 


Re: New to moddin, kinda new to site, long time gp lover

O.K. here are my current mod plans....PLEASE feel free to "rip on them" if they don't make sense...it's how I'll learn:D
1. Yella Terra 1.7 rockers
2. LS6 valve springs (90# installed w/ Manley retainers for maximum lift of .580")
3. LS7 lifters
4. INTENSE stage 1x ( duration @ .050": 212º/216º, lobe lifts: .327"/.321", valve lifts with 1.60:1 rocker arms: .523"/.514", lobe separation angle: 113º, intake centerline: 109º)
4a. new timing chain / dampener
4b. port / polish heads & LIM
5. reprogram OVERKILL PCM
6. port & polish TB?
I read that the MAF needs tweaked for the TB modification, is that something that needs to be done "in car" or can I have Will include that in the reprogram?
 
Re: New to moddin, kinda new to site, long time gp lover

Sorry, forgot to add that I will be replacing ALL of the valve stem hardware (retainers,locks,seals)
 
Re: New to moddin, kinda new to site, long time gp lover

If my math is correct (a BIG if !), then my stock heads SHOULD be able to support the total lift needed. Is there another reason not to run cam/rocker combo? I AM new to this so please feel free to comment:)
 


Re: New to moddin, kinda new to site, long time gp lover

performance cam has a different profile vs the stock cam, rockers on the stock cam just make the valves travel more.

but a performance cam will make the valves drop and rise faster and longer duration. aka choppy idle and more over all power. no rockers needed.

You really need an in car tune if you're camming it.

what cam is best for n/a? thought id go for zzp's gt1 cam.
 
Re: New to moddin, kinda new to site, long time gp lover

Changed my cam selection to ZZP GT1, total lift will be .5389, well inside the safety range ZZP stated. I am still number crunching,: making sure that the valve lift #'s are good for the entire duration on the cam. Looking for a tuner to complete this project. Anyone interested?
