looking for loads of stuff for my 3100, HELP!

[no_doz]

im looking for certain parts to really up the performance of my 96 3100 (lumina), if anyone can help me find any of the following i would REALLY appreciate it!

.60 or .80 oversize high comp pistons (the highest compression that i can run with 93 octane without problems).

peformance cam-pretty much anything, preferrably something that will up the power in the higher rpm range

intake setup- i intend to put a hoodscoop on it & run the intake to it, so at higher speeds the vehicle will get more air/cooler air.

ecm upgrade- some way to improve the power via the computer, & most imporantly to REMOVE THE SPEED LIMITER.

headers-anything that will fit in the stock location.

larger injectors or tb-anything that will up the hp this way (like 3400 tb & or injectors, whatever will allow me to get the MOST fuel flow that i can get).

o2 sensor emulator- i intend to run straight pipes with 2 high flow japper mufflers on the back, so i need something that will tell the computer that the o2 mixture is as good as it should be.

also, just as a curiousity, would 3400 or 3800 heads work, & if i could get all of these things, could the transmission handle it?

thanx guys

www.donkeypunchperfomance.com has all those except for the cam and bigger TB

you can buy the TB here and get a regrind cam from a good machine shop

IIRC the tranny wont hold up to alot of mods

ecm upgrade? why do you want the speed limiter gone i doubt you'll hit it in the 1/4

headers you can make your own

larger injectors won't do squat on a stock engine even with a cam and hybrid swap i don't need larger injectors

3400 heads will swap on the engine but you'll also need the intakes, you can keep your head and swap newer intakes on+ a 3500 uim and 4.3 vortec t/b

3800 is a comepletely diff motor

gotta do some searching its all there

IIRC the 3100 cant be bored over that much

any pistons will have to be custom made though, i would suggest the move to a 00-03 3400 and a base turbo kit to start with, that would provide yu aq great platform to get started with and will give you plenty of room for future upgrades

[Syn]

people are getting together a gp on moons site for 3400 forged pistons i am sure they could make 3100 pistons as well

[no_doz]

well for one thing, in no way am i going to go turbo because im not gonna pay $3k+. how far can the 3100's be bored? also are you saying the the whole vortec 4.3 head/intake will work, or that the intake will bolt up to my stock shit, or that the intake will bolt up to the 3400 head? about the speed limiter, my main goal is to get that off & my reasons are my own, so if someone could help me find a way to do so i would REALLY appreciate it. see i dont intend on putting 1000's in this car, im just looking for a way to make it a decent amount faster & to kill that damn speed limiter, what i listed is the most i would ever do to the vehicle. oh and does anyone know if a jet pcm will help the power a lot & remove the limiter?

oh and donkeypunch is down for god knows how long.

I dont recommend the 4.3 TB cause you need an adapter, have to open up the plenum for 70mm, and 70mm is a PITA to take off with cause throttle resolution is bad. Ive got the adapters taken care of using a stock TB or one of the billet TBs on the store here. I need to talk to marc on adapter pricing but it takes care of the cable bracket mount as well when using the 3500 plenum.

You can bore it .060 over but I wouldn't recommend going any more than you need to since there isn't much to gain from it.

Speed limiter is set in the computer so you would need to reprogram it. DHP can take care of that for you.

We will have a dyno done using the 3500 plenum and 65mm billet TB on an otherwise stock 3400 grand am and we have a before dyno as well. There will also be a dyno done with a 56mm TB which is a cheaper option but im pretty sure that the 65mm is going to help considerably even on a stock motor. That is the stock size of the 3500 motor but since the 3500 uses a cableless setup you can't just throw that TB on there.

[no_doz]

who is dhp & how do i contact them? and what you are saying is that i can get the most bang for my buck if i use a 3500 head, plenum, adapter plate, & 4.3 tb, but it is a pain in the ass? now what do you mean about taking it off to 70mm, & what are you talking about with the whole bad throttle resolution thing?

[SappySE107]

Im saying don't use the 4.3 throttle body. I didnt say anything about the 3500 heads either. If you use the 3500 heads, you will have to use the 3500 lower intake as well and those aren't cheap plus you would have to modify your exhaust manifolds to use the 3500 heads or make headers.

The 4.3 throttle body is 70mm. Thats too big basically. Throttle resolution means you can't give it a little bit...its a lot. Anything over 80% throttle or so is the same as WOT in that it doesn't do anything for you as there is already no restriction in the throttlebody at that point.

[no_doz]

so i should do what, go with the 3400 heads? will they work with my stock exhaust? also what tb should i use to pump as much fuel as humanly possible & get a nice power gain? oh and about the 4.3 tb, so what you're saying is even if you barely throttle it-it will respond a lot, not just lightly like it should? oh and what would happen if i used one (theoretically) and had it wot on the 3100?

[SappySE107]

THe 3500 top end would work as well but its not easy to come by. 3400 top end is a lot easier to find so its cheaper and will net you a nice gain. That is exactly what I was talking about with the 4.3 TB. A larger TB doesnt pump more fuel in there, just air. If you go WOT on a 3100 with a 70mm TB, its not going to do anything more than it did at 80%. Maybe even 70% since the setup I drove was a 3400 with a cam and high compression.

[no_doz]

couldnt i set my computer to pump out more fuel with that tb?

[SappySE107]

If you get a DHP powertuner, yes. digital horse power is the company.

[Syn]

a word of advice a 4.3 t/b on a 3400 intake isn't gonna fit well, i was gonna have a adapter made and there just isn't enough manifold to port match it

[no_doz]

will the dhp tuner remove the speed limiter?
