what's wrong with your engine now? I had 111k on my 3.4/auto and sold them together with the harness and stuff for $700

You'd probably be better off just using a 3400 upper intake manifold. I think it would still work with the 3500 lower. It also looks a lot better than the 3500. For fitting under the cowl, you'd just have to grind off the lettering.

idk for sure what the advantages of using 3400 pistons are...with the 3500 heads and stuff I was told I could just keep a stock bottom end (another reason you're better off using 3500 heads instead of 3400 heads).

 

nothings wrong with the engine now im building another one so i still have my car then ill have no room for an extra engine to just sit around

with the intake im trying to kill some weight so if i can get rid of the bulky *** fuel rail and the aluminum upper for plastic i figure i could save like 10 lbs (every pound counts)

 

the 3500 upper is plastic? really? didn't know that. I bought one, got it in the mail, found out it wouldn't fit under the cowl, and never took it out of the box lol.

 

ya i think the malibu is aluminum and the g6 is plastic im not too sure but i know the g6 is plastic

 

Hate to rain on your dreams but....

Grape of Wrath from the FTV6 forums already built a 3.4L turbo.

 

well the Malibu and the G6 are the same car under the skin, so it wouldn't make any sense for them to be different. It's exactly the same motor.

 

thats ok its still cool

ya it is aluminum but the 3.4 runners wont line up to the G6 lower and i read that along with the poorly designed heads the runners dont allow good flow on the 3.4

 

which "runners" are you referring to?

 

the intake runners on the 3.4 wont line up to the lower intake off the 3.5 and did you see that HUGE article i posted here the other day on the 3.4 (prob not you have a LT1) but it said that the runners on the 3.4 dont allow enough flow

heres the link to the post

and specifically
"I then realized, in 1999, that Pontiac’s Grand Am GT was making 175hp/205tq from a 3.4L OHV FWD motor. I did research into this engine and found that GM had worked a different path on this motor and it was better than the 3.4 RWD. I did more research into engine design and found that runner lengths help determine how much power and torque the engine gets. I looked at the plenum and runner design on the “3400” engine as well as the 3.4 RWD and realized that the RWD runners were jokes. At only 2” long and without any type of airflow acceleration present, they looked like all they served was a means to get the air from the Y shaped plenum, which once I saw a cross section – laughed at, to the cylinders. That was when I decided then and there that the plenum and air intake system was the 3.4L’s weak point."

 

... i may not be shedding too much weight with that monster but hell if i get power than were all set
