Yeah... good luck. I'm not expecting to have any more than 230-240 whp with the top end swap and cam. I think you'd be better off to just have a basic rebuild done and do the GTP top end.

now that i re-read the sight i see it wont be that much so its kinda pointless being so much more expensive.....im waiting on the damage report to decide....1.)topend 2.)rockers(i have the HPV its said to dyno better than cammed cars with rockers n insert) 3.) camshaft

Im probably going to rebuild it and throw some good rockers in there to work with the HPV insert so i dont lose gas milage with the cam but still have the same performance and dont have to worry about spring or timing chain......any one suggest a rocker pachage should i go with the 1.6, 1.9 ive read good things about the zzp 1.9

has ne one read about the 1.84......i am very eager to figure out a conclusion so when i hear the damage report i can buy or not.....if i do nice alluminum rochers should i get #105 springs and maybe even new aluminum valves too or do i need seal and locks new if i do the valves as well?

You could go with a VS cam. You can run it on a stock timing setup (no need for heavier springs) and get benefits of a cam and about 10hp over rockers throughout the rpm range.

If you change springs, you'll need new seals. Locks can be reused. If you go with any of the 1.8-1.95 ratio rockers you have to do springs to get the most out of them. That puts the similar wear on your timing chain/dampner as running a XP/S1X cam.

Look at it this way: the only consideration is gas milage.

• With a VS cam/rockers, you lose very little. With an XP cam, you will lose more, but it's still manageable (people are still getting high 20s on the highway with an XP).
• Timing chain/dampner wear will increase with rockers/XP due to the required spring weights.
• A cam install with the motor out is the same price as a rocker install w/ roller rockers.

It's something you're going to have to decide for yourself. I chose the cam route (should be here Fri btw). If I did go rockers, I'd run the roller rockers ($400), not counting the springs. You'll have to run 105s and change your chain/dampner too for insurance purposes. Something else to consider is the 1.95:1 ratio offered.

BTW, valves are a waste of time unless you're having the heads fully ported and larger valves installed. If you're going that far, why not install a cam?

thanx rook thats prob the best explanation i could have wished for.....the only reason i was gunna do the rockers is because of that intake manifold insert i have allready which is said to dyno better then a cam with rockers.....Im looking to get the most power out of my car because the engine is out now without stroker or top end swap so if i did cam whats the most power for cheao the XP like u did?

XP is the largest cam you can run without having the lifter guides machined. Plus it gives a nice lumpy idle. Everything to do the the cam install was $660 shipped. This included the cam, 105s, modded retainers, valve seals, install kit with cam/crank bolts and valve covers, and a new timing chain. Rated hp is 40-55 range.

The S1X cam sold by Intense is very similar, though just a hair smaller (you can compare the specs). Either would be great for ultimate power on stock heads.

Honestly, if you want to go with reliability, just get a VS cam. You'll still get benefits higher than the rockers (for cheaper) without the timing component wear associated with the larger cams/rockers. You'll also get your mileage.

If I'd went VS cam, the whole setup listed above would have cost me about $200 less, because you don't need the springs, retainers, or valve seals. Highly suggested imo. If my GP was going to be a dedicated DD, it would have gotten the smaller cam.

thanx again rook ur an awsome help

Stock springs, keepers, retainers, lifters and pushrods are fine. Springs, retainers, and pushrods are recommended for shift points over 6200rpm...........should i be worried about this i have the zzp pcm n she shifts pretty high

I believe the ZZP default shift point is 6100 so you can run the stock components.

thanx everyone for your help VS here i come.....unless the damage is bad wish me luck ill prob be finding out Wednesday when im in california

(in the zzp website for the options in the PCM it states [tables adjusted for VS cam $30] should i be worried even if the its not above the 6200 shift point labled on the cam description)

I would go cam too. I was debating this same thing and every time I drive my car now, I'm glad that I went with a cam instead of rockers. Since the motor's already out, I would recommend like Rook said, either the XP cam or the S1X cam from Intense.

If you do decide to go rockers, get the ZZP ER rockers. They are the best ratio for N/A applications and they will maintain the best drivability along with gas mileage/etc. Fuel economy isn't so much about your mods, it's how you drive and how well tuned your car is. Right now I just avg'd 16 mpg for my last tank with the top end swap/cam, and that's untuned, running rich, idling rough, and beating on it pretty good. With a solid tune and feathering the pedal I'm sure I can get 20ish in town like I used to.

You don't need a reprogrammed PCM, but the one with VS tables will take into account the changes the cam makes and be better tuned to the engine. It's whatever you want to do. Perhaps ZZP will reflash it for a smaller fee.

very tru if so i might just have them program it for the xp because i wan the most power wile its apart maybe throw out that extra $200

So your going to do a top swap? you say your going with a VS cam great you do know this is for SC applications? The vs cam would not be a good choice n/a if your staying n/a I would suggest a GT2 cam and since you will probably need head resurfacing get themm to shave 30k off them this will boost your comp.ratio to 10.2-1 ,to make real power n/a the secret is in head and cam combination which will cost $$ so in a lot of cases it woulld be just as cheap to do the top swap ,PM me for a little head help .Chico.
