You want to talk power? When at my trip to ZZPerformance Thursday, they had a '00GTP with our L-67 engine on the chassis dyno, for 2 days. Blower had a block off plate, and a turbo kit added. Internals unknown. 474 wheel hp! cost: $13,000. And they thought he was going cheap because he could have removed the blower and put in a better intake system, and he used shorty headers, not equal length tubes.
Turbos are where the REAL power is. HOWEVER, Zoomer has the worlds fastest BLOWN front wheel drive 3.8, runs a 9.01! That's why I deal with him.
My future plans? power wise, next will be a SS intercooler. $1,000 installed. Then headers, 1.8 roller rockers and springs, then a cam. Somewhere along the way either a gen V M-90 or a M-112 and a ported manifold. My gen 3 is obsolete. Heads? Looking to bore and stroke it to 4.1 someday. Smaller pulley each time. I like my blower. Not a turbo guy. Not on my Intimidator SS, anyway.

Out of curiosity why are you going to run the roller rockers AND a cam?

Wouldnt that be kinda redundant since essentially the two items do the same job, just in different mannors?

Plans for my car are quite simple.
I want a quiet stock looking DD that still can swallow the 13 second passes reliably (not too far off from realistic)

For exhaust:
SLP y-pipe into the stock mufflers. A high flow resonator and. zzperformance downpipe (weld in style w/ cat)
ZZperformance Power Log (coated)
ZZperformance Crossover (coated)
ported rear manifold
and modified stock rockers 1.9 (just throwing it in exhaust for hahas...

For Intake:
custom...kinda.
should have a full writeup this week for you all!

Blower:
poretd housing
3.25 pulley
gatorback belt
ZZperformance intercooler

...that setup should be amazingly streetable and easily dip into the 13's on a good tune.

 

The roller rockers will help with any cam, including the one all ready there, plus will help with a cam with more lift. Rollers can be installed easily, a cam is more involved and more serious a mod.
I seen these power log pipes, and they are ok, but for real power you still need true equal length headers, and ZZP confirmed that with me. This 474hp car had power logs.
A short stack intercooler can be installed easily, and under the factory hood. 30hp, and .1-.2" smaller in pulley size. I'd like to run a 3.0" pulley without changing cams.
ZZP sold me a NAPA belt, as they didn't like the gatorbacks. They feel the full contact is better.

I cant really justify running a cam since im not going for a 400hp car.
...not to mention its just one more piece of the puzzel for error.

As far as the exhaust manifolds are concerned, on higher output setups (such as the mentioned setup above), yes...you need to run an equal length setup. BUT...once again, im going for streetability and im certainly not looking to loose any low end torque.

From my understandings, the plog can handel upwards of 300whp, and i dont plan on excedeing these general limitations.

I have just found time and time again that less can be more when particular items are chosen carefully. While product A may provide exceptional gains over product B in a given setup, it does not necisarily meens its always ideal.

Im not basing this build specifically on price, but more than less efectiveness, and i would have to dish out 600+ dolalrs for a set of manifolds, when i can simply purchase modified units which will be just as effecient in this setup for a fraction of the cost.

...but all and all i could be completely wrong too
we will just have to wait and see.

 

Adding a power log manifold is a very economical way to add power and lower KR for your engine.
The big HP GP at ZZP used them. Here is the link.
