Has anyone on here s/c their trep and if so what did you use roots, centrifugal, or screw type.
Second what is the difference in boost pressure form a s/c to a turbo. i've looked through the page and much to my surprise i haven't heard to much about it !

Try using the search button it's been talked about many times..

[paintballdude05]

The biggest hurdle is the ECU/PCM. Chrysler won't give up how to crack it so the engine won't be getting enough fuel.

[blue_02]

you haven't heard about it because it is nearly never done. read the other 1000 threads like this and you'll find the general consensus is that if you're going to spend as much as it would take to t/c or s/c an intrepid you could just buy a faster car.

[Chewievette]

well duh you could buy a faster car, but if everyone always just bought the faster car the hot rodding world would be a totally different place. basically if you want to do it right it takes a lot more money and effort than most people in this community have been willing to put in. My only advice is keep researching until you have absolutely everything figured out, if not then you will just be wasting your time and money on a project that will ultimately under perform and cause you headaches.

well lately i've bee looking a the intakes of both the 3.4 s/c 3800 (gm) and the 3.3/ 3.8 and they dont seem to be to far apart from each other. on cheeetah onlile they have an garolite intake spacer for the 3.4 dohc grand prix engines ( r pettey edtion) and also i have been to autozone and looked @ both intake manifold gaskets and the appear to be the same ( in layout) but the bolt pattern is different. All bolts line up to our block except the 2nd, and the 3.4 (gm) have the same intake manifold as the 3.8 (gm). so it's not that far off but i figured i'd check here first. as for buying a faster car "why spend 10 grand to be an asshole when you can do it with 5"

[Chewievette]

I'm going to go ahead and openly doubt the gm intake will work on our engine. it might look close, but the airflow knows the difference and will let you know by performing poorly.

btw, 3800 is a 90 degree block, 3.3/3.8 is 60 degrees. so yeah, i doubt the manifolds swap.

[The D.A.]

IDKT.here's an example of why they should be close, but i'll agree the airflow will be different. I still havent found the thread w/pics of a s/c 3.3 longi or transv. I tried pricing a centrifugal but that in it self cost more than my entire project. That first & third pic is from cheetah online for the 3.4 and the second is from a trasverse 3.3/3.8

[Chewievette]

the manifold looks more like a 3.5L because it doesnt have the gaps between 1&2, 3&4, 5&6 like the 3.3/3.8L does. I made an adapter to put the 3.5L upper manifold on a 3.3L and the flow was bad enough to make me remove it.

Hey after doin some more research the 3.4 IS a 60 degree v6 !!!!!! It's posted on the gm parts direct site.@http://www.gmpartsdirect.com/performance_parts/store/catalog/Category.jhtmlCATID=172.html Here's what it said.....

"Chevy 60-Degree V6
The Chevrolet 60-Degree V6 is a compact powerhouse. This innovative engine has beaten both the competition and the elements in off-road racing. It is a proven winner in sports car racing, and it has a promising future on America's oval tracks in the Midget classes. A Chevy V6/60-degree engine is the perfect power-plant for a high-tech street rod or an ultralight autocross machine. GM Performance Parts offers the basic building blocks for a high-performance V6/60-degree, including light alloy engine cases, high-compression pistons, and high-volume pumps.
Chevrolet's 60-degree V6 has been produced in two distinct versions. First generation V6/60-degrees have cast iron cylinder heads with inline valves; second generation engines have aluminum cylinder heads with splayed valves. First generation engines V6/60-degrees are produced for front-wheel-drive and rear-wheel-drive vehicles exclusively. Parts are interchangeable between the two versions except as noted in the part descriptions below.
Chevy V6/60-degree engines are available with 2.8-liter (173 cubic inch) and 3.1-liter (189ci) and 3.4-liter (207ci) displacements. 1985 and later V6/60-degree blocks have larger main bearings than pre-l985 engines; these late-model blocks are recommended for high-performance and competition applications. All Chevy V6/60-degree engines use metric fasteners exclusively."

I was talking to one of the local cops ( their chargers are the 3.5 v6's) and he showed me the supercharger kit for the car it's a procharger c-2 centrifugal supercharger. i just checked their site and the price is not listed for the unit. there is hope @ the end of this tunnel !!!!!

[Chewievette]

that kit is quite a few grand..

GM engines are not my specialty, but I have friends that are.

[Daytrepper]

Here's a second gen setup, maybe it can be adapted?

[nitromonster]

Hi are one 3.5 HO
it is what on the second picture
a+++

[The D.A.]

That is Farkun Amazin'
1. How much did the unit cost ?
2. Are you're internals forged (were the stock internals forged or are they aftermarket)
3. What are the dimensions of the engine assembly w/ the Super ?
4. How much boost are you going to run ?
