bone stock but would like a little more boost

[jdaniel1983]

I just bought an '87 GN(my 1st) thats all stock and I was wondering what kind of chip to use to gain hp and boost. I don't know if I'll need to use a bigger fuel pump or a boosta pump or if i even need to worry about that. Also where's the best place to buy parts for these cars?

Any of the vendors on the home page are great. Start by getting a scan tool like Scanmaster to monitor knock, then upgrade fuel pump and get a hot wire kit for it. Depending on your goals you want to look into injectors before ordering a chip. A bunch of guys have luck with TurboTweak chips and adding boost is as easy as bolting on an alky kit. BUT, before you add anything to up the HP, read, study, and read some more about these cars.

Good luck and congrats on the purchase!

Id definitely look into getting a newer fuel pump and hotwire kit at FULL THROTTLE SPEED - Store Front Page

The stock pump is old and should be replaced ASAP.


Id look into getting a TT chip, everyone is using them, they work great and you can make adjustments with fuel and timing. TurboTweak Home


Do you plan on keeping the car 100% stock?

What are your ultimate goals with the car?

Will I Need A Scan Tool Or A Fuel Pressure Reg. To Use A Bigger Fuel Pump? This Car Has 135,xx On It And Still Has The Original Paint. It Runs Good And The Turbo Seems To Work Good. I Just Want A Little More.

Don't necessarily need a new regulator with a bigger pump, the regulator will still hold it at the set fuel pressure regardless of the pump, but with 100k+ miles and being 20 years old the diaphragm inside the regulator can start to get weak, no point in spending the cash for the fuel pump if you're going to stick with the old regulator.

You don't NEED a scan tool either but it's better if you have something to monitor for detonation and watch if you're running rich/lean etc.

Also if you haven't yet, head over to gnttype.org and go through their "spring cleaning" guide to freshen up the car and make sure it'll run strong.

If you want to stay close to stock with a little more kick I would do...

-TurboTweak Chip
-ScanMaster
-Fuel System Upgrades (pump, hotwire kit, adjustable regulator)
-Less Restrictive Intake/Exhaust systems
-Duttweiler neck for the intercooler (known to free up about an extra 2lbs of boost)
