Research for future project, Need Help!

[DigRun?]

Looking to start work on my engine this summer, i don't know too much about the turbo v6. I need some help to get me started in the right direction.

I want to do a full roller cam conversion, including more lift, possibly more duration, and i want it to lope pretty good at idle any thoughts, is this at all possible? Where do i find info on the full roller conversion, and parts?

I also want to get some GN1 heads, along with 1.6 ratio rockers, any opinions on these heads and/or valve train? are there any problems with them? Also dose anybody have any for cheap , looking to spend as little as possible.

all input is appreciated, i want to get this done with as little surprises, and problems as possible. Thank You

Cams "with a pretty good lope at idle" and turbos don't mix too well. Turbos like shorter duration cams to keep the exhaust velocity up so they will spool relatively quick.

It's possible, but not easily.

That is what we call a "Sonic" cam. Sounds good going thru Sonic but won't run very well. Usually guys that have that cam have the rear of the car jacked up high in the air with 12'' wheels sticking out 3" past the fender lip and air shocks. :biggrin:

Yeah some cams will sound great, but like Mikestertwo said, you really need something that performs good compared to something that just sounds good. There are a lot of cars out there that have a near stock idle that will outrun almost anything they meet. Good example is the Comp Cams 206/206 roller.

If you want an engine that will have power high into the 7,000 rpm range, if that is truly your goal, you will need the proper intake duration number. Intake duration is the factor that dictates where the engine power curve is going to fall. There is no substitute.
If this is going to be a fast food go-getter, then install the small cam and save yourself some headaches.
If you're the type of person that is savy on the subject of pulse tuning, and have the resources to properly tune your manifolding to take advantage of it, then you're certainly going to end up with a monster. Study the size of cams that the big boys use, not the street guys, if you're serious about this project.

If this is a budget street deal, you'll be better off installing the small cam. To make a large duration cam work will cost big bucks.

Get the 210-215 from Mike at FT It idles somewhat lopey or a bit lopey & pulls good. Your not getting that High lift 350 sound so forget it since your looking to be on a budget. Now if you have +50K to drop for fun you can do anything soundwise!

Buy a 3/4 raSe cam from JEEEEEEEEEEEEGS.

What race is that cam? Asian? African-American? Indian? Hispanic? Caucasun?:biggrin:

Lopy idle cams for a V6 make tham sound funny anyway. Except THIS lumpy cam. Just opne a BIG wallet to make your car sound like this: http://www.youtube.com/watch?v=4bkt...1-sometimes-you-just-gotta-start-over-33.html

DOH!!! A long time ago I built a NA 3.8 for my lil sister's Pontiac Sunbird Formula. Ported heads, 272/282 duration cam with .474/.484 lift. It had a nice lopey idle but that car would rev to 6,800 and pull the whole way. Had a 5-speed in there and everyone who lost to it swore it was a V8 until they counted the plug wires. I would stick to the smaller cam for turbo setup for street use.
