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

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.

If you want, PM me any questions you have... I can get a TE44 to run mid 11's easily...

Or PM me for my number... I tune some cars around here, and my own

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.
