Thread: I need some help with mods

Hey I was just wondering What would be a great list of beginning mods. Im looking to get into the 13's rather quickly, so Id like to know what all to do I have a 2004 GTP Comp G, So help me out thanks guys...

intake is a good start! then i'd go w/ a down pipe!

No don't go that route. I'd get intake, stat, plugs, headers, then a pulley.

heres the order I went. All these mods were installed withing 2 weeks of each other:

thermo, downpipe, wizair, pcm, plugs

going to plog then 3.6 pulley next. I'm guessing this is going to put me at a 13.9-14.1.

04compG what are you running right now?

Not sure. I'm ordering the plog and 3.6 pulley right when I get back from Pennsylvania at the end of next week. Someone on the other boards had an 04 compg with my current mods (i think he had AL104 plugs though) plus the plog and 3.6. The car ran a best of 13.9 just a few days ago. It also had a run of 14.

i'm going to try to make it to the local strip once I get the pulley and plog on. I want my car to run consistant high 13's also so I might have to think of another mod or two to do after the pulley and plog, depending on what my times are. I think its a good idea to get rockers and springs if you are going to drop to a 3.5" pulley on the GenV and that costs a lot of $$$ so I want to avoid that and still get consistent high 13's using only new and what I think are the best parts ( which of course always cost the most money).

Yea, if you are content with the Pacesetters get those instead of the Plog/dp combo. The pacesetters are made out of mild steel though and theres a reason they are substantially cheaper than the competition. I would have wanted the ZZP or SLP headers and your looking at $1,000 + install.

Just get some SS Autochrome ones, they're stainless steel SLP knockoffs and are only like $360 shipped.

Well they dont make headers for my year from there, and also how big of shot can we spray on these things?

with 125 shot, you didnt notice any nitrous pops or knocks or anything like that? How much power can our internals actually handle?

The 3800's bottom end is pretty stout, as it is. Kudos to GM's over engineering it.

It's not so much a question of how much power it can handle. It's all in the tune. Some uncontrolled knock in a high HP setup will tear it to shreds. You'll probably find most high HP failures come from detonation and not the HP directly.

Two types of forces at work in an engine. Inertial forces (inertia of the parts, specifically pistons and rods moving back and forth), and power forces (force of the expanding gases pushing on the pistons, rods, and crank). Inertial forces are many times that of power forces, so increasing power doesn't add that much to the total load felt by the hard parts. If that makes sense.

Safely then Id be able to run a 100 shot without too much KR, is there a cheap tuner out there to reduce KR? what other supporting mods do I need... and can anyone tell me of a great NO2 kit for 500 or less... thanks

the older headers 03 and older work on our cars also 04+. the pacesetters are a little bit of a PITA to get on because its a tighter squeze on the 04+

ill put it this way. last time out at the track i ran 14.6 at 91. i was breaking up, up top. i had a sparkplug wire not all the way on. next time out with my pacesetters on and EVERYTHING in perfect running condition, im gonna try and break 13's on the stock tune. most will problew say its not possilbe but we shall see. if not im shooting for LOW 14's.

also if you dont want to do your own tunning overkill highly recemended. :: Overkill Motorsports ::

blowfish what are your mods? you want to run low 14's with pacesetters, intake and plugs?
