  1. #1 Mod Suggestions For Beginers

    These are 1/4 mile times to be expecting after the said mods are done.these are estimates.Very close estimates to my knowledge



    I was Attempting to give some help to a member when i was asked for my opinions...There are a lot of good posts already about what to do but most importantly what not to do but i figured the more the better. Again these are my opinions and am no way saying this is the only way moding should be done nor am i trying to talk bad about any company or indivdual in particular....Feel free to give me any constructive thoughts on my comments...heck i could even learn something out of this...and im sure there is something that could be altered or put into better words...again i did my best...If you dont like it dont look....and thanks go out to any one who has actually help me to learn any of this info for myself...







    I did my best and mainly based my statements on times and combos that i know would acheive these times...i do a lot of reaserch and talk to a lot of people and also pay close attention to there mods...i was a tenth of a second off of guesing what my actual time 1/4 mile wise would be on the first trip to the track after my mods on my grand prix...same with my mustang...again this is what I feel will work best...it is you money and i want you to spend it how you want to.Not how i want you to.Most importantly if anyone has ANY questions about ANYTHING that i have mentioned or think there is a better way please let me know.Its hard to say exactly when to buy what to save you some money because i dont know how much money anyone has and when they want to spend it...and it may be hard for you to figure this out also (it was for me lol)...so again i did my best...




    I have come to the conclusion that- With stock heads to reach an e.t. that is less than mid 12's you are going to need an intercooler.This being because you are very limited in cam choices and kr will likley be present at an undiresable level at the time you reach mid 12's. This combo should be good for high 12's for sure.



    Tuner-500.00

    XP hot cam-300.00-best cam for stock heads

    105 springs and retainers-170.00

    Pacesetter headers-359.99-uncoated

    Autolite 103's-10.00

    180* t-stat-10.00

    valve seals-18.99

    3.2 mps-100.00-I am at 86% inj duty cycle now with a 3.2...Although people say that you cant go under a 3.1 with stock injectors i would not recomend going under a 3.2 with stock injectors.

    belt-25.00

    s/c coupler-30.00

    northstar 77mm tb- 355.00-The reason i picked the n* tb over the zzp 78mm is because it comes with a lq4 maf sensor...this level of mods would be pretty close to maxing out the stock maf sensor...wich you would then need a lq4.the 1mm difference in the tb bore size would not matter.

    nitrous-at least a 75 shot-500.00

    s/c ported matched inlet to match bigger t/b-Talk to Reptile

    s/c ported outlet-Again, Reptile

    cold air intake-180.00

    maybe a shift kit-100.00



    The total for this is around 2700.00 probably including the s/c porting work. And again should bring you to a high 12. You want to go faster? onto the next package.


    This combo should be good to real low 12's.Everything above plus...


    2.9 pulley-50.00 (since you already have the mps)-smaller than a 2.8 would require the s/c snout to be machined.

    42.5# injectors-239.99

    f/s intercooler-1000.00

    built transmission-1600.00?

    slicks-300.00

    after market resignator and muflers-?

    new belt-25.00

    ported heads-?



    Now this does not include gaskets or any of the small stuff that doesent really cost much..but does add up..so don't forget about that.With stock heads don't worry about getting higher ratio rocker arms...stick with the stock 1.66's,when you in the heads go ahead and replace the valve seals...they pop out and the new ones pop right in.



    now this is some of the reasons why i belive the below kit is not a good choice....I have added a note onto some of the part listing endings..



    This is what the stage xx kit has:

    Comp Cams custom cam and upgraded Comp Cam valvetrain components-may not even work on stock heads...does not specify..and what valve train componets are upgraded??? probably bull**** stuff...if it were anything big like lifters ect i think they would list it...probably valve locks or something lol...20 bucks for those lol

    Thrasher Transmission Shift Kit ---not a bad ide and may help your tranny clutches last a tad bit longer when reaching low 13's

    SLP Performance Parts Coated Exhaust Headers with 3 different downpipe options----slp is just plain expensive with the same overal design as others

    PRJ Performance Ignition Wires----good wires but stock will do just fine---stock coils also

    DynoMax Super Turbo Cat-Back Exhaust System with the option to upgrade to the SLP “Loudmouth” Exhaust System---again does not specify anything..you do not need a turbo exhaust when you do not have a turbo...will likely hurt you more than anything...turbo exhaust is usually anywhere from 3 1/2'' to 4'' sized piping and when a turbo was present would help the turbo spool up quicker reaching max boost

    Digital Horsepower Inc. customized PCM.---no no and another big no..i would never do this...even on a stock car...i was going to get one but then quickly changed my mind after doing some reaserch...

    your choice of either a 3.4”, 3.25”, or 3.0” pulley ---3.0 would surely require bigger injectors wich they do not offer in this kit...so it AMAZES me why they would even offer a 3.0 pulley...very bad on there part.

    your choice of either a Press-On Pulley or the upgraded Thrasher Modular Pulley System--mps all the way

    Thrasher Cold Air Induction Kit with the option to upgrade to the MSP Cold Air Induction System---ummm this is preference but i like my jmb

    Goodyear Gatorback Supercharger Belt---way to expensive...i think the prices START at like 35.00...just get a gates or napa belt

    160-degree or 180-degree SLP Performance Parts Thermostat---kinda preference here also...i have a 160 but a 180 may be more benefitial.

    Optional Coolant Recovery Bottle for 1997-1998 owners-you need this if you have a 97-98 as stated

    Optional Intake F-duct for 1997-1998 owners upgrading to the MSP CAI System--im not sure what this is-i own a 1999

    Optional Thrasher Supercharger Pulley Puller Tool for Rental or Purchase---get brian to press your mps hub on when you do the s/c porting

    well mine ran a 14.65 with a 2.1 60ft with off road dp and a p-log with hp tuned shift settings and a maf tune....tuned tranny tables are good for about a tenth in the 1/4 for sure...if you can get a good 60' then i would say a 14.8 wouldnt be to far fetched at all...there are a lot of factors though.....

    What do you think I should run w/ 3.4, 104's, 180*, 3" DP, CAI, 1.9 rockers, ZZP PCM? Impala SS is the car. Trying to get into the mid 13's!

    I wouldnt run this combo before getting full headers. fwiw I know a guy with the same combo as you mentioned but with pacesetter headers and STOCK rockers and he is getting around 3-4 degrees of kr...wich is not good...i am thinking the 1.9 rockers that i am about to put on his car will help a lot with that issue along with tuning his pcm for him...should be fine then.



    as for mid 13's...i my self am in the 13's now...the mods in my sig is what it usually takes....you could chage it up a little though like for example...


    instead of the fs intercooler get the shortstack and run the 3.2 (i wouldnt go much lower in pully size with a ss though)

    or replace the 1.9rr (leave stock ones on) and the fs ic with an xp cam.....just some examples...with the above combo you will blow up you car before it even thinks about mid 13's...with the above combo you would probably run a 14.6 because of all of the kr you would have...

    A 3.6 pulley is what you should run.

    I wouldn't recommend a SSIC to anyone. I had one on my other GTP, it couldn't hold a candle to my full size I got on my GTP. No comparasion, either get a real IC or get no IC at all. Don't make the mistake I did. You absolutely cannot over intercooler a S/C or a Turbo. There going to produce a **** load of heat. Why get rid of half the heat? Doesn't make sense to me.

    As for starter mods if I was starting all over again on another GTP, the first mod would be a full sized Intercooler. You can find nice used ones out there for the same price or cheaper as an SS IC, why not get the best? After that would be an open cone or a CAI, next 3"DP w/ no cat, next 180 t-stat + coolant flush, next Autolite 104s + new wires, next interchangable Pulley system w/ a 3.4 and 3.25, then finally a good tune from Overkill and that would be for starters. With those mods and tuned it should be able to run a 3.25" w/ no knock.

    It's all about what you want out of your car ....dont get a dp if later down the road ur going to be getting headers...it's a waste of money since headers always come with dp's...I would suggest headers for a mid 13 second combo like you stated

    imo anything in the 13's low 14's you are being held back by the stock mani's....if your running mid 13's you've wasted a lot of time porting the hell outta the stock manifolds and could gain quite a bit more than what is normally seen in switching to headers if that were the case...wich i dont see that happening--I havent even heard of anyone running low 14's with stock maini's but i guess it's possible

    Headers are always a step up in performance....you may lose a little low end tq because the headers are more free flowing than the stock...but you will gain some hp for sure. And also be setting a solid path for future mods. Pm me before you put those on if you end up getting them...I got a trick that help out. Shoot who knows we may be doing it at my house lol. Fwiw you probably wont even be able to feel the little bit of tq that is lost on the bottom end
