I have made myself a TSM motor for my Buick GN. Should push anywhere from 700-750whp. Fully rollerized motor, 9 -1 comp, steel crank, crower rods, J&E pistons, ported heads, welded and raised intake, Precision plenum with RJC powerplate, 83lb injectors, GTQ70 turbo, ATR headers, Racegate, FAST system etc etc. I will pull out my current motor this weekend and dump this bad boy in. Its just a shame we have a **** load of snow. Not being able to drive it is going to kill me

 

 

 

Cool, are you the GN guy on the board, like you and your dad have one???? I remember awhile back I think someone from canada posting their dad's and their GN so figured must be you.

 

ya that thing is going to be badass

 

damn, what sort of power figures are we looking at here?

 

Looks good. Just trade out the Turbonetics Gate for a Tial and you'll be perfect.

 

I love it

 

 

Rhman19- yes that was me

Turboteggy- Thats a Racegate, not the boost creep Deltagates. This one is good for 1000whp. Holds boost steady as ever. Definately wouldn't take a Tial over it.

 

do you know mike st'eves with duttweiller GN motor in the vette? that car is unreal!

 

Ya I know Mike. We are practically neighbours. Within spitting distance of each other. Real nice guy.

 

Sick drop it in your DA

 

very nice

 

Niceee! That looks sick man.

 

Nice! My cousin has a GN with a few mods and a little added boost w/ a rebuild. You are a brave man that is a lot of power.

 

holy crap.
i seriously need to come over in the spring

 

GN's are one of the few domestics idi drive, theyre badass!

 

be sure to take plenty of pics

What size exhaust are you going with 3", 3.5'?

Shout me up bro, as long as you don't grab my arm when I am driving like my other buddy does. Its all good.

 

FredoSP- I am running a 3" exhaust on the car, but when she goes to the track, the downpipe comes off and my fender dump goes on. I have some vids of her at the track last year, but I don't have a clue on how to transfer it from my camcorder to my computer. If somebody knows, holla back.

 

LOL.
no worries.

 

gn's are cool, cant you get like 900-1000 hp out of the stock bottom end?

maybe not.

 

mikes hard GN

 

550-600 whp is all I would feel comfortable pushing on a stock bottom end. Only has a 2 bolt main. Thats when you step up to a stageII motor. Same motor with thicker walls and 4 bolt mains. Also comes with 12 bolt holes per head instead of 8 (which means more boost woith out lifting the head).
