Hey been floating on the forum for a while just now getting around to posting. While I dont ahave a monte myself I work on my girlfriends quite a bit lol. I have a 03 grand prix n/a 3800 soon to be a turbo 3.8. Trying to join a few different forums for info. So if anyone is swavy in the ways of turbos plz shoot me a line.

 

We have a couple people who are very knowledgeable in the area.

to the forum!

 

Welcome Chad.

 

Welcome to mcf, I'm one of the turbo guys.

 

Welcome to the forum. I don't have a Monte myself but this is a great forum to be on. Feel free to jump in on the Members Blog and tell us about your life.

 

Welcome to the forum. Even though you don't have a monte still post pics of your grand prix. It is like a monte except the Pontiac edition. haha My dad used to have an 02 grand prix and I used to like to drive that car.

 

Welcome to the forum!

 

Ok then turbo guys. Give me some advise I would like to get close to 400 hp. Plans are like this some kinda stage one or stage two turbo cam. Head porting and valve unshrould e85 with @lease 42 pound injectors and walbro pump. A t3/t4 turbo if I can get way with it front and rear power logs and exhaust. Dyno tune by brian I plan on running 1.6 rockers again I got the zzp e.r rockers on my n/a motor but will be selling them soon. Dont plan on building a king of the mountain motor just something to have some fun with. Will welcome any advice.

 

You can probably get 400HP just by running the ZZP Z7 kit with an intercooler, very minor supporting mods (headers, HV3, 60# injectors) and getting a good tune. Brian could let you know if you are about to outflow the stock MAF and need to upgrade that.

Then start saving up for a TEP trans.

 

Can't use headers with a turbo setup but zzp z7 kit uses front and rear plogs. You can make 400whp without heads I'm thinking but a cam will be needed. You will need a 3" downpipe which I believe the Z7 kit has and you will want a cutout on the down pipe to have a free flowing exhaust to make more power. You will probably max the maf as well at that power level. A racetronics 255 with a rewire should be good for fueling and I suggest 60# if not 80# injectors if running e85. Make sure to upgrade valve springs and use a double roller timing set if running a cam.

I also suggest saving money for a TEP trans!!

I take it your talking about brian turner at dyno tune motorsports (aka the angry dyno midget ) he is a stand up guy and will lead you in the right direction. Give him a call he will give you some advice as well. He is who tuned my car and I'm beyond happy with his service!!
