New to Turbo Buicks, help with goals...

[TurboDetroit]

Purchased a 86 GN as a roller and ready to put some power behind it. I already have a built rear end with eaton 3:23 posi, and a guy waiting to beef up the tranny, but need help with power goals.

I want to be in the mid 10 sec range and i want some of your proven guys' advice on how to get there. I have full interior/ AC delete. This is pretty much a friday and saturday night street car that i won't beat on too much with very few track passes a season.

The rjc intercooler looks really trick and i think i must have one just for cosmetic purposes, haha. But i would also like to upgrade the turbo and run an external waste gate.

Are aluminum heads necessary to get into the 10 sec range, 70mm TB? Really don't even know where to start. I dare to say I'm more show than GO.

Also, need a good turbo buick shop in the metro detroit area!!

NO ya don't need alum heads to run 10s or even 9s.. 1st thing is to get a pile of $$$ Here is a simple build we ran years ago.

We have a local GN that has run a 10.9 with an un-opened engine, just proper bolt-ons and good gas!

For a mid to low 10 sec. GN, some up grades like Grumpy mentioned should be done.

Probably the best advise I can give you is find someone that has been SUCCESSFUL in building a GN to the level you plan to reach, and follow their recipe.

In general, to mod a GN to be reliable and perform consistent at the 10 sec. level requires a budget of ~$10K.

X2 !!!! anyone can slap a mess of parts together... takes a little talent to keep it together

 

[TurboDetroit]

yeah, sounds about right to me. I was speaking to a guy down on woodward about his GN, he told me that theres a guy who works for Macomb CC thats a genus at turbo bucks, anyone know him?

 

[Nick Micale]

I worked on one of your 10 sec. builds today Dan, after 25 years the module/coil pack finally gave up on Erik's T!

If you really want to go fast, here's where you should start first. http://turbobuick.com/forums/threads/info-for-new-turbo-regal-owners.380856/ It doesn't seem as cool as just buying go fast parts, but knowledge is the key to getting these things to fly and stay together.

Here's my car and combo. http://turbobuick.com/forums/threads/my-87-gn-cruise-air-10-55-et-21-mpg.370097/#post-2958149

That's Bruce at Aggressive Auto. Groesbeck and 16mile. http://www.aggressiveauto.com . He is the only reputable Buick shop in the area that I know of. He has a few things to my TB and proven to be fair priced and honest. I would highly recommend if you need parts or wrenching.

 

[TurboDetroit]

Very informative @spoolfool, Thank you..

 

[TurboDetroit]

@inkncontiverto that's it... Thanks alot. I really like the work that I seen of his...

First mistake, 3.23 gears. Stockers are 3.42 and most guys keep that gear.

Yeah, the rear end was already done when I picked the car up... Is it worth it to step up to 3.42's?

Yes that rjc front mount IS sexy... It's just as cosmetically pretty as it is functional...

Short answer. Yes.
