Thread: New-ish GTP questions

Alright I bought GTP a few months ago. the kid i bought it from said it had 180*T stat, 104plugs, pcm, and 3.4 pulley. and said the tranny was re geared. I didint bother checking any thing, Drove it 5,000 miles and threw a rod. i took it all a part to find out it was bone stock expect the 3.4 pulley. As im putting a new motor in, I am putting 180*T stat, 3inch Down pipe, u bend delete, 104 plugs. and a tuned PCM. would i be safe running the 3.4 pulley?.. And my other question is about the tranny. at about 70 MPH i sit right about 3k RPM is that normal?

my GP runs at 2200ish at 70. check out the safely modding you 3800 thread. it will tell you wat you need to no

So would you say there actually was some thing done with the gearing? I dont know i just thought 3k RPM was high for 70?

Is there any way to find out what the actual gearing is?.. and maybe that would explaine why it seems quick outta the hole? ha I dont really have much of a clue. this is my first car that I actually pulled a motor in and pretty much my first time doing any thing with a car be for it was all about the dirt bikes / pit bikes lmao

pretty sure the only wat to find out what gears r in it wound to tear into it. i wouldnt like it cuz i do alot of highway driving and that would SUCK gas.

Yeah it shifts into 4th. the kid told me what gears were in it but i dont rember. let alone who knows if he was lying. i do recall it sounding like it was out there. I think he said some thing about 4.xx gears? but I could be 110% wrong too i just rember it being bizzar.. but i got the car fora steal he wanted 3,000 talked him down to 2,500 then when i seen him i swiftly talked him down to 2,200 then 'counted' my money and 'realized' i only had 1,500 on me and my buddy 'happen to have 150 on him that hed barrow me' so in the end i got it for 1,650 haha. I think his daddy bought him the car and he has never seen that much cash so he was ready just to have cash in hand latter that night his dad called me complaing saying i ripped his son off. and wanted me to give him a nother 1000. I told him tuff he shouldint have let his retarded son go by him self to sell his car.

Oh and for headers that will be my next buy once i get the cash. but for temp would it be alright if i were to cut off the bottem part of the front manifold and re weld a bigger tube in? I seen some where they were saying the front manifold has the most restriction..

What do you mean by "hog it out"? is there a easyer way then cutting off the lower part of it and welding a new / bigger tube in ? sorry i am pretty new to all of this ha :/

And witch PCM would be better ZZP or intense?
