What's the difference and how could us 2.8 guys change over to a 3.1 TB?

alls u would need is a 3.1 tb,and a new vacum line were it connects from the manifold to the drivers side valve cover.

on a 2.8 the tb has a large line that runs to the back base of the manifold,were it tees to the valve cover as well

on a 3.1 there is no line from the tb to the manifold, just the valvecover to the manifold.

u could pick up the required parts from a junkyard or somone on the boards dirt cheap



anyways flanges are in i got 5 sets
1 set is already used up for firstfirebird so i have enough left to make 4 manifolds.
so if u want one let me know

Are you only making 4 more or are there going to be more made as you get in more orders?

Nice work. It looks alot like the one I made about 4 years ago. They work. I have a rare and discontinued FDP 62mm billet TB made specifically for a thirdgen f-body 60*v6 on mine from a guy over in Sweden- factory TB is 52mm. My plenum volume is 4.1 qts- I sit slightly lower than yours by milling out the area where the shraeder valve would hit- thus I have no problem with hood clearance.http://www.cardomain.com/member_page...52_35_full.jpg

I like your TB, have you ever had that setup Dyno'd? I'm curious if changing the manifold and TB would help all that much since the heads seem to be the main problem.

I'm planning on fitting a Northstar 75mm TB on one of these manifolds , Dave is good at helping us out.

EDIT : HPE; I got those flanges made, if you need something PM me and I might be able to help (a good friend of mine has a CNC shop).

I have talked about TB size in the past around here. Going to a TB that large will cause a stuble or hesitation in flow because it is just too large for the draw of our engines. It will level out an work fine if opened slow and smooth, but crack that thottle open quickly and it will stumble. 65mm is about as large as I would recommend and even that is pushing it.Note for fact.stock 52mm tb = 308 cfm's62mm tb = 435 cfmsA built TPI V8 motor is running dual 52's and they are twice our displacement.Don't go 75, you will regret it. My opinion of course, but I am just trying to help you not make what I think is an expensive mistake.

Got the TB for 50 bucks including the IAC and TPS, so it's not an expensive mistake. You think that's too much for a boosted motor?
Actually, if you want to discuss this more, let's do ti in the appropriate place...

Firstfirebird, How much would it cost for just a set of flanges for the intake?

firstfirebird

iTrader: (3)

Dave, how do you feel about people buying the flanges that you paid for the programming?

boostedv6

Ok. So Dave, how much would you charge for just a set of flanges?

So, anybody ever install one of these UIMs on stock engine yet, or any NA intake even with minor mods?

What kind of power and mileage changes did you get?

actually first firebird will get his in a few days,and rob will also have one

firstfirebird

I was going to ask you about that .

firstfirebird

iTrader: (3)

NP, It's not like I have a running car to put it on (actually it's running, just has a slight knock, lol).

Blue1989RS

I totally forgot about this project! I'm really interested as well.

Did I miss it?

Qoute from Cheech Martin:

iTrader: (5)

^^^ True, Dave hasn't been on here in a while. He kind of disappeared for other reasons.

tank12983

anything going to happen with this?

2.8RS

iTrader: (5)

Dave has kind of dropped out of the V6 world. Not sure what went on but I think some problems back home for some reason or another.

If any of you guys still talk to him, ask where my TB, cam and manifold are. He was supposed to TIG some stuff for me in trade for my cam, but he kept it all.

^ He's still around, and this is what your stuff went toward, John....

Street Lethal

iTrader: (16)

^ A bunch of us are patiently waiting to cross paths with him at the track, but we haven't met up with him yet. Will definitely let you know when we finally do though....

Although my cousin Rob wrote this guy off awhile back, I still feel that the guy owes my cousin a very large sum of money. I really do hope that you get your money back from him John....

So i take it these intakes were a NO GO??

Street Lethal

iTrader: (16)

^ From what my cousin Rob told me, the intakes were poorly made anyway. He never braced them properly on the inside, as the top center section of the plenum would cave downward whenever he put a load on it, you could even see it happening at idle if you looked carefully....
