Re: First cam install, planning it out.

ZZP has Comp OE lifters, OER's are loud yes, I have been running them for 45,000 miles. For 6500 RPMS I would also run Comp 130lb springs and a double roller since you have it apart , also a oil PSI kit to raise your oil presssure since you want to shift at 6500 RPMS and run a trubo. Also don't run lightweight pushrods they will warp , I would go with Comp 5/16 or Comp .105 pushrods.

Re: First cam install, planning it out.

Hmm so which rockers should I get? I see the yella terra come with push rods (now realize why its $399) and they are also 10% lighter than stock . So instead of light weight rods which ones should I be using? Do you have a recommendation? Also what do you think of the cams? Which would be better with a future turbo setup?

With 130lb springs would I need forged pistons?

Re: First cam install, planning it out.

i would not recommend shifting at 6500rpm, the stock block, cast pistons and cast crank are not made strong enough to withstand frequent high rpm useage like that, especially on a small cubic engine with a large stroke

Re: First cam install, planning it out.

There quite a few shifting at or above 6500 rpms but have 130lb or plus springs and a double roller like Teful Hyuden he shifts his GT40R turbo at 6500 RPMS and makes 455 WRHP and 500TQ at 18-20 PSI stock block except for springs and timing chain. But I wouldn't shift that high 6000-6200 is enough depending on your cam and turbo specs.
If you have the cash forged pistons, L32 rods and Clev. 77 bearings is a good idea, Comp pro mag roller rockers( depends on your heads and how much lift you can run), Comp .105 pushrods, Comp 130LB springs, and a double roller timing chain would be your best bet. Cam is up to you search through some threads to see who is using what.

Re: First cam install, planning it out.

ssms5411,

so I can go with 130lb springs (avoid valve float) and run 6000 maybe 6200rpm without forged pistons?

**ssms5411** · 03-13-2010, 01:40 AM

Re: First cam install, planning it out.

You'll need a double roller with the 130lB springs, as long as you watch your air/fuel gauge so you don't run lean and have no KR and maybe a methanol kit to help reduce it , should be fine. I wouldn't shoot for 600HP but 400-450HP should be good.

Re: First cam install, planning it out.

Good call on the double roller timing chain. For the turbo I plan on using the GT35R. As for 600hp, heh I wish :). I'm not hoping for 600hp on the first shot. I'd be more than happy @ 300whp+ with the cam + turbo (low boost to start) + tune. Once I'm there I can start to shoot for 400+. Id rather take it slow and learn everything, not just blow motors up.

I have a feeling a 450hp camaro is going to be a lot more fun to take out for a nice drive around town or to an event than a 600hp one. I'd like to properly retire this car from regular use, but I don't want to lock it away and use it on track runs either. I guess it depends on what you can live with. There are supra guys here running around with 800hp+ to the grocery store on r compounds :-/. Most will admit their car was a lot more fun at <600hp.

Re: First cam install, planning it out.

So should I even replace my rocker arms?

**ssms5411** · 03-13-2010, 08:39 AM

Re: First cam install, planning it out.

Don't have to , depends on your cam specs and your heads, guys run stock rockers with 450 WRHP so I think they are fine.

**Blizzard242** · 03-13-2010, 04:29 PM

Re: First cam install, planning it out.

You have to use the pushrods that come with the yella terra roller rockers.

http://www.3800pro.com/forum/cams-he...r-package.html

And from what I've heard the pushrods that do come with them are pretty good. I've got some and I've had no problems so far.. That I know of.

Either way, if you need replacements I'd call up Intense-Racing as yella terra was working with them I believe to get those rockers on our cars.

Re: First cam install, planning it out.

Ok so here is what I'm thinking:
-----------------------------------------------

$109.99 - Cam Install Kit L36, #4, VC Gaskets, Cam, Crank Bolt, No Dampner - From ZZP
$157.99 - OE 850 Lifters - From ZZP
$99.99 - JP Performance Double Roller Timing Chain - From INTENSE
$139.99 - Crow Cams 130lb Valve Springs - From INTENSE
$24.99 - CompCams Performance Valve Locks - From INTENSE * do I want these? *
$29.99 - Manley Performance Valve Spring Retainers - From INTENSE
$95.99 - INTENSE 5/16" x .038" x 7.05" Oil Restricted Pushrods - From INTENSE

I still cant decide on which cam to go with for a turbo down the line. However minus the cam, is this everything I need for the cam install, to run 6,000 - 6,200 RPM without valve float and to be future proof for a turbo? I can go with stock rockers with the turbo cams right?

I can't seem to find anyone around here with hptuners :-/. I called a few fbody/vette/etc.. shops and they all seem to hate on the v6's (ie. "we only do 8's") even if asking if they could delete some codes and adjust for tires, remove speed limiter, etc.. They seem rather snobby. I talked to Secret Services (import oriented shop), they have hptuners and do lots of reputable turbo work. I can get a full tune including 2 hours of dyno time and any changes I want, etc.. they want $750 to do it. If I come back after turbo or to make other changes I get discounts after that. Does this seem rather reasonable?

Re: First cam install, planning it out.

750 is a lot for a tune IMO, i got mine tuned over the summer with several pulls on the dyno, a base street tune, and fine tuning on the roller for <$300 if i remember correctly. keep searching around for a shop that has good rates and is more willing and you'll be all set. i had to drive about 2 1/2 - 3 hours to get the right shop, but they did great work and will give me discounts on future tuning.

oh yeah, and i'm pretty sure you could buy all of the software you'd need to do it yourself for less than 750 --- keep looking bro.

**enzia35** · 03-21-2010, 10:52 PM

Re: First cam install, planning it out.

Shouldn't you go through with new rockers anyway? I'm not really sure how all this stuff fits together, but 1.7's should give you a little more power over stock 1.6's.

**OneEightSeven** · 03-22-2010, 12:02 AM

Re: First cam install, planning it out.

@BallerMaro13

I was pretty pissed the GM shops were being snobby :-/, their listed prices were a LOT less. It's not like the import place told me "haha you dont have a supra, go away". Don't get why it's got to be that way :P. I'll keep looking around. $750 does seem like a lot. I could get hptuners pro for $750 then my own wideband. However I'm also not experienced with tuning other than knowing how it's supposed to work in theory. I've read a lot about using hptuners, but have never used the product. The shop in question ($750) is a very reputable shop and as I understand it further tuning will be $500 for another full day or on an hourly basis for minor changes. I've drooled over photos of their stunning looking manifold fabrication before :drool:. If I have the money I'm definitely having them fab stuff for me. That's their specialty.

@enzia35,

I've heard that stock is fine if they're in good shape earlier in this thread, but I'm also going for a turbo build later so I'm not sure if higher ratio would be the way to go with the turbo. Would it make sense to do 1.7 ratio?
