No love for the 3100 v6

[96gtcoupe]

Hey. Just got back on here more frequent due to an accident in a crx (stupid honduhs) anyway...still have my GAGT and am still having difficulty finding stuff for it. I see posts for 96-96 ga stuff like pullies, headers etc but NOTHING for the 3100. A swap is out of the price range right now, but I do have a muffler shop thats gonna throw some flowmasters on the gt, but is the stock piping efficient enough or should I go larger? Maybe somewhere down the line I will get a highflow cat if its viable along with some headers if they evern exist. I took off the air box and slapped a cone filter on it (generic for now, but I want something better since pep boys filters look all metallic and not near the quality of say a weapon r or k & n, but its a start. My engine light is on because the iat sensor has no pipe to stick it in yet, any ideas? I also want to increase the throttle response since it feels like I gotta work into the accelerator to really get some speed going, if anyone can help with that, I'd be grateful.

Oh if anyone that answers is in the Raleigh, NC area and isnt doing anything tomorrow let me knwo and we can hook up or something.

Unfortunately there isn't a lot of love for our 3100's but there is a little. What are your plans for your car? Do you want more go than show or what? Anyways, the most I can say from my own experience would be to do exhaust (I would probably go a bit bigger than stock and run it all the way back), a custom cold air intake instead of just having your cone on there (I've done it on mine so ask and I can help ya out, it's not too difficult, and relatively cheap to). Maybe a P&P might give you a bit more power.

They have some stuff that you'll probably be interested in, only thing is they are a kinda pricey. Look at this thread, you'll probably find what you need also...

For show stuff, the possibilities are almost endless. It all comes down to how creative you can be and much money you want to spend.:)

[voyager]

drill a hole for your iat sensor.

fastforwardproducts and mantapart make underdrive pullies for the 3100. jbodyperformance makes headers for lotsa $$$ ( more than a swap! ). i'd upgrde the entire exhaust piping to mandrel-bent 2.25" pipes from the downpipe back; maybe 2.5"... either a custom intake or one from tranzgenic ( does dr. speed make one? )

you're right, not much market for the 3100. i'm probably going to pull mine out and put in a 3400 down the road; not as if there's any more market for them either.. but alot is interchangeable.

the UD pulley will increase throttle response quite a bit.

[litdevil316]

there market for everything. just that once you find it, it will probly cost ya alot of cash.

[Azrael]

Headers for the 3400 (S&S and TOG) will bolt right up to the 3100. But those headers were designed for 99+ GAs so there might be some custom work needed on the headers or your firewall to get them to fit.

[litdevil316]

damn that custom work bit. lol

[95-GT]

3100 and 3400 are the same thing :idunno:

Get the p/p'ed heads, intakes, and TB for the 3400 and it will bolt right up to the 3100. The UD pullies will bolt right up. The cam coming out this summer will drop right in. There isnt much of a differance.

[litdevil316]

dude, *evil grin* 3400 powered 97 gase.... that would be nice

[95-GT]

What about a 3400 powered, turbocharged, Limited Slip Differential 3400 in a 95 GAGT

Oh wait, its coming in less then 30 days.

[litdevil316]

funny funny. but that would be nice. blowen 2.4L coming in a few months maybe

but a 3400 in a car that weighs less then a 99+ ga, would be nice

[95-GT]

Whats so funny abotu it? I am waiting for my LSD to come in. I already have the 3400 with the heads and intakes done up installed. Turbo goes on as soon as my LSD arrives.

[Themeneea]

whats a LSD?

[Colin]

That's the stuff everyone was doing in the sixtys ..... But i think it now means , Limited Slip Diff . ...:D

[95-GT]

Yep. Limited Slip Differential.

[litdevil316]

lol. the legal LSD.

[95-GT]

mmmmmmm. legal LSD :drools:

lol

[coupe]

What i wouldnt give for LSD. You lucky bastard.

1st I want to say thanks to all who responded. I will definitely use the info nicely. Already sent out a pm to help with the custom cai and will get with my muffler shop to see about the 2.25 inch piping, but with the flow masters I wont sound like a Honduh rice rocket right? A nice tone but nothing too loud..thats what I like about the GAGT's low tone growl, not obnoxiously loud. My other question was for 95-GT; are you doing an entire swap or just the heads & tb p & p'ed ready for a turbo? If its just the head and tb p & p ed ready for a turbo and (damn is the LSD on the 3400 tranny already or custom work?) I will personally get with you on mimicing the same, cause thats sounds tight. If its the entire swap, then thats out of my budget for a while. Thanks and thats a nice project their, cant wait to see the results. Thank you for the info, I will be doing a lot of mix and matching since 3400 and 3100 are the same (didnt know that :eek: ) If the price of the 3100 headers are more than the total of the 3400 headers and labor to make them fit, then Im rollin with the 3400's!

[wiccanferret]

Just watch out when doing something like headers. The motors are, for most purposes, the same...but you still have to deal with the rest of the car. The main problem with the 3400 headers is that they hit the firewall on our cars. So with some custom work, you could do it...but that's if you have the means to do custom work.

I have a whole 3400 dropped into my car, not just the upper half. I swapped it into my car over a year ago. The whole upper half (heads and intakes) is gasket matched. I am using the 3100 transmission (4T60E), and buying the LSD kit from Phantom Grip and installing it on the differential myself. The entire swap costs just as much as a top end will cost. Total for it all was under $600-$700. And its not a project car, its a daily driven, street legal car.

The best route would be to drop a 3400 in there, get the LSD, and turbocharge it. All in all, it will cost around $4200, give or take a few hundred. If you need help installing anything, I am willing to lend a hand, but I do charge. Not a lot, but just for my time to drive out to where ever and gas costs.

[96gtcoupe]

I will seriously be taking you up on that when the funds come in!

[95-GT]

Where do you live at? Say a motor costs $500, if I have to go there, then I will charge like gas cost, and maybe like $200-$300 for my time or something, with you providing tools also. If its done here, then gas cost is out of the question, and same amount for labor because I have to provide tools.

[96gtcoupe]

Raleigh, NC and thats in my price range too! Where are you at? It may be better for me to go out there to you since the engines are that cheap out that way.

[95-GT]

I am in SE Michigan, Sterling Heights.

[litdevil316]

any one sell a LSD for the 97 auto?

[95-GT]

For the 2.4?

[96gtcoupe]

How far from Detroit is Sterling Heights? I've been to Detroit and Flint, Michigan. Oh, how long did the initial swap take you?

[95-GT]

First time it took around 8 hours. I can get it done faster now tho, maybe like 5 hours? I am approx 1 hr from Flint and Detroit.

[litdevil316]

yea, 2.4 auto 97

[95-GT]

Do you know what transmission is in there?

[litdevil316]

um, you got me there. it what ever 4spd came stock in it for the 97 year.

[95-GT]

Appears to be the 4T60E, and Phantom Grip makes one for it.

[SPECIALGAGT]

The GM part offered as a "stroker kit" for the 3.1 engine is basically the crank and pistons from the 3400 block. 3.1 and 3400 deck-height are the same. Has anyone here done a Throttle-body replacement on the 3.1, '96, with the airmass sensor removed from the stream? What's the largest bore that can fit in here?

[TA^Guy]

Dig you get a new shovel this weekend?
Not that it's a bad thing but it just seems your digging up alo tof old threads. :lol:
