Mods that can be done to 3.8l v6 series III 2007 grand prix

**sevenhellz** · 02-07-2013

i just bought my car with 58k miles on it. its a 2007 base grand prix with out a supercharger.
just wanted to know what kind of mods can be done to my car. every time i try to look into it
i only find things for the gxp v8 grand prix. if you could provide the difficulty level of the mods
and the prices of how much everything would cost would be amazing. also i like in Livonia Michigan
and was wondering if there's any performance shops around that mod cars like mine or tunes them
sense i found out i cant chip my car.

There isn't much that's worth your time and money.

Perhaps a downpipe or headers and an HV3.

Also consider cleaning your throttle body.

Shift kit might help get you up to speed quicker... Maybe weight reduction lol.. Just get a top swap.. Cheaper insurance

Shift kit won't do anything for speed. Just quickens and tightens up shifts.

My vote: Top Swap. But don't go too crazy. Apparently L26s don't like boost.

so why did my car stop accelerating when i reached 110???

**Fivefingerdeathpunch** · 02-09-2013

Speed limiter.

You don't need to go that fast anyway, and the trans isnt always fond of those speeds.

are there any performance shops around Livonia Michigan that can tune my car? my throttle response sucks and the way it accelerates after 4000rpm is week. if it makes the most amount of hp and torque above 4500 rpm then why dose it just rev up and not accelerate nearly as hard after getting to 4000?

Because grocery getter. Tuning will do nothing more than liven it up just slightly. You won't have a racekar until you get boost.

the mods I have in my sig made a good difference in the upper RPM range, off the line its still slow but once its moving and then you go WOT it does better then stock. dare I say I can keep up with a L67 on the highway

**Grimsin** · 02-11-2013

Ya with my mods its cleaned half a second off my stock qtr mile time, not too shabby.

A shopping cart with a cripple pushing it could keep up with a L67.

He won't be whining about it though..

**sevenhellz** · 02-12-2013

also does anyone know where i can get this bumper? Attachment 10893

**REDCRAPGP** · 02-12-2013

It's not a bumper it's just a extension that you can attach into your current one. You can get it at a dealership. P/n 19120590

Warning; get out the lube and bend over and prepare to pay out the buttocks

**sevenhellz** · 02-12-2013

Sure is. A few ways you can do it is hit up a junkyard and find a Grand Prix with duals and purchase it and bolt it on. Or you can have any decent exhaust shop weld a y pipe into it and add another muffler or buy one of the exhaust systems from our car (pricey) so I would tell you one of the first 2 options.

**sevenhellz** · 02-12-2013

is there a website that i can buy that specific extension? if so can u provide the link? iv been trying to find it and i cant seem to

**FordMan77** · 02-12-2013

You could try car-part.com They may have it. Heck, even RockAuto may stock it for that matter.

**REDCRAPGP** · 02-12-2013

Gmpartsdirect.com

Enter that p/n

It's a GM specific add on part. Dealer only unless you get lucky in a junkyard or something so no rockauto wouldn't have it.
