Thumbs up New Gn owner

Hey I'm picking up my 87 Buick Grand National this weekend and I have never worked with any kind of forced induction motors. Wanted to ask a few questions.

Are their any extra maintenance that comes with a turbo?

Anything I should look out for while running the car?

The car is pretty much stock with a te44 turbo,cat-back, and drag radials
Any other mods I should look into short of pulling the motor?

Thanks any help is appreciated

Cool, should be fun. For an excellent source of Buick turbo-specific info, check out turbobuick.com.

you may wanna check out bgnra.org and turbobuick.com thats all they talk about over there. as far as mods i use to own a grand national. get a front mount intercooler and make sure and i mean make sure you upgrade the fuel system. buick motors dont like being reved high. get a wide band o2 sensor. and you can also get a electric dump right before the cat. and also a shift kit. you should run some real good 11's with that combo.

Thanks yeah I've already ordered a better pump and regulator. Any thoughts on the stock intercooler? The car runs 12.4 right now daily driven so I'd like to get it into the low 11's so I can play on the street with it.

You can easily do it on the stock intercooler. Get a new chip from Eric Marshall (Turbotweak). An upgraded turbo TE45a or equal. A 3600 stall, And alchy if you want to run more boost w/o race gas. We've run 10.50 on a 45a w/ tires and race gas.

My name is Rosewood T-Type on TB.com or you can pm me here.

I'd get a te61 turbo, champion heads, front mount or alky, a 3600 stall and some 60#ers. I have a te44 with some champion heads and the turbo ran out of steam. Beofre the heads I could run 24#'s with alky and now I can't get over 20#'s with the heads.

Thanks Everyone for the info. I pick the Gn up on friday and its going to Hrp that night.

I need some info on a in car boost controller and also how do you determine how much boost I can run without just taking it passed it's limit then knowing.

You can run as much boost as you have octane for... for a stock IC, I wouldnt recommend any more then 15 PSI.

I see 20-21 psi on my stock motor car... have seen 28 on 110 octane

I always ran 16 on 91/93. With the alky I ran 24#'s on 91/93 with zero knock. If you get an in car controller it will slow your spool some. The closer the controller is to the WG the less lag you'll have.
