Comp ductile iron roller, how does this sound:
206 / 206
.539 / .521
112lsa

This will be with PTE FMIC, Champion heads, probably a te45a (Yes, I know my turbo selection changes every day) want quick spoolup, street car, Propane injection.

What do you guys think?
 
That cam should aid in quick spoolup, SHould be good to around 5500 or so,What is your actual goal in et?
 
If I turn it up to 26-28psi I want to hit 10.80 or so, street trim 18 psi or so I want 11.40's. Am I missing anything important? I know I could maybe use more injector than 57's, but I'm thinking the Propane will get me there if I really need to crank it up. I would rarely need to crank it that hard...there's only 2 street cars around here that are possibly capable of running that fast.
 
Well I spec'd it that way, do you think this is too much lift? Someone tell me before I make a mistake. There doesn't seem to really be a turbo buick specialist at Comp for recommendations, so we were just brainstorming..
 
Iron heads or aluminum heads? Irons don't flow much past 500 lift, so there is no need for a cam with more lift then that. Aluminums seem to like more lift, since I think they peak out @ around 550 lift, so a little more lift in a cam will not hurt with aluminums. Figure out where you want to shift the car, and what kind of converter you are going to run. Matching the converter and the cam, will be key in placing the car in the correct power band where it will make power. HTH

It's not a bad thing, just I've never seen a 206 with that much lift.

What kind of lift does an iron head like? Mine is a 210/210 roller with .523 lift with 1.65 rr's, iron heads race ported and polished. Made alot of hp with this set up.
 
I did not know that the irons peak out lower, I will be running a 9x11 3200, but I can get it restalled while the trans is out if necessary. I don't really need to shift high, 5500 max, this is mainly a street car and I want fast spoolup. I think I will be running a te45a, but it has a .63 garrett housing on it. Should I leave my converter at 3200 and get the 212/212? I didn't see a Comp roller 210/210 listed anywhere. My rr's are 1.55's. Thanks for the input, help me out, I HAVE to order the cam today.
 
Why are you complicating things? Comps off the shelf 206/206 .496 .496 is perfect for ported irons and quick spool up........What's the problem? :confused:
 
Basically Comp's info says the 206/206 roller is a good stock replacement, I don't feel that Champion heads/FMIC/big turbo are stock type parts, so I want to maximize my combo. Will it get me to the high 10's? I know the cams don't really matter much but it seems like there would be something to gain. Correct me if I'm wrong.
 
That cam will go low 10s and spool like mad. In other words, that cam will go faster than your projected goals.

You said street car, it will run perfect on the street.

Your brain is getting confused with so many choices. You might want to get a plan and stick with it.

Sounds to me like the "little" parts aren't what you want to hear are best. On the street smaller parts are quicker and just all around better. Is the 45A the best choice for "your" street car? Not in my opinion......
 
You are right, I am a young guy and this is the first time I am actually trying to build a FAST street car, my TA is just a fun daily driver, but I really want to be able to set the GN on kill and do so if I want, like the majority of the GN's that are 'done right'- I have been having a really hard time trying to plan this combo. Do you think that 'new' GT6152 would be a better choice? I found the TE45A used with a coated .63 garrett housing, new hd actuator and polished housing for $890 shipped, where as that's what a new GT6152 costs. My builder says the TE45A would be great but it does seem a little big, thanks Russ, I look forward to your input.
 
The 45A is an awesome turbo, no doubt. For a quick street car it needs a pretty high stall converter to help it get going. I would rather have a quicker spooling turbo and a lower stall converter for a street car. I think the GT6152 is a much better choice. With ported irons, the 206/206 roller and the GT turbo, and ALKY :D , that thing would be pretty quick!!!! Oh and with alky, forget the front mount. Unless you already have it.

Get rid of the KB cold air.

Never mind, I see you have a 3200 stall......

Seems like a lot of lift for a 206/206 (Almost as much as my new cam) but I don't see how that will hurt you. Your heads/springs can handle the lift for sure :D Are the lift #s with 1.55 rockers? I know sometimes Comp likes to show everything with 1.60. Should be good on the street.

TE-45A is a tad big for your goal, but will give you room to grow later and once you hit your goal you will want to grow :) You can run 10.80s with a TE-63. Maybe even as small as a 61.

That's kind of what I was thinking, ported heads with 1.55 rr's would squeeze a little more lift than stock heads like the 206/206 is rec'd for, but I can't get anyone to say they've actually tried it. Maybe I should just stick to the off the shelf 206/206 .496/.496, all numbers were spec'd with my 1.55 rr's. The GT6152 seems like it's doing well, but I don't know the specs on it, it's really just a PT61 with a new exhaust wheel right? I had a TE62, old school turbo, how will this compare. PTE FMIC is on it's way!
