i did a quick search but aint seein much. i figure bein how long it took to get a hot air down pipe option, and a 3" with integrated wastegate to boot... at least 8-10 of them should've flew right off the shelf, right? i love my 2.5 pipe with the rjc wg flange, and its a perfect combo with the ta33, but i'm fixin to go bigger turbo, and i'ma thinkin it wouldn't hurt to have a wee bit more diameter. i'm not concerned about performance reviews, by the pics of it, no doubt a nice flowing piece. i'm concerned about fit. i want to know if its hitting the control arm, bottom of heater box, side of heater box, if not, how much clearance? i have fresh motor mounts, as should you, of course :smile:
tia for any replys
 
For what its worth, i personally think you can't have a better downpipe that will fit the hotair and still retain the a/c. im kinda byist since they used my old downpipe to make theirs. So with that being said my downpipe would clear the control arm by at least a inch from what i can remember (i have hr parts motor mounts) also it would clear the a/c box however the little metal plate that protects it i had to bend mine some for it to clear but it was fine after that. IMOP if you still have a stock downpipe or wanted to upgrade you cant go wrong with the new 3inch g-body downpipe.

NOW BUY UP PEOPLE
 
ideally, im looking for 12's in my car... 12.99 or better would be awesome... I had the mease 3" dp, but when times got real hard, I had to liquidate the nice pieces out...(thanks Jerryl for helping a buick bud out!!!)

I currently have the ATR stainless up AND down pipes, but 2.5"...

Think they will suffice once I get the t33c in? I would be running alky and an 87 comp with all the mods listed in the speed/combo thread...ie ported everything and a cam...

600 is a lot of dough plus shipping for a DP, but what other choices do we have????

IMOP since you already have a nice aftermarket unit stick with it. ATR made some nice stuff. now if you didnt have the ATR unit then yes you need it but i think the 2 1/2 will be more then enough for what you have.
 
Mine hit the heater box hard! Didn't fit right at all.
I have another laying around that I don't want to use because
of this. I have 2 ATR 2 1/2" and they fit just fine on the
same cars. Brian just missed it, I think.
 
6togo, was it hitting the bottom of heater box or the side of it?
 
It hits up hard on the forward side (toward the front of the car).
Plenty of clearance on the bottom of the heater box.
I bent the heat shield to allow it to barely bolt up.
 
thanks for the reply 6togo. if you've bought 2 pipes, and don't like how they fit, your definetly being more tactful than i would be about it, lol. just a couple more questions, if you don't mind. by looking at the mods in your signature, you've obviously got some exp on these cars and no doubt know what your doing, but just to confirm, your body and front header-to-frame bushings are all in good shape and not all smushed down? motor mounts are newer? i know the hr mounts sit a little higher than the stockers. also, are you using the stock hotair turbo mounting brackets to mount the ta49's? and... are you using the stock exhaust housings on the 49's or the precision housings?
 
Well, I am not at all sure that I know what I'm doing!
But, I have not replaced any engine mounts, the
turbos mounts I used off the stock HA turbos and I
used the housings that were on the turbo when
I got them, not sure what they are - they work. : - ))

Ok I know Brent keeps saying off of his pipe. Which Brent correct me if I'm wrong was a Mease pipe? I helped Keith build that back in the day & sold alot of them. So the pipe we built should have been exactly the same way a Mease pipe was built.
If you guys are having problems either post some pics up or e-mail me. No 2 cars are the same & your going to have some saying it hit & some saying it fit fine. Then you have some saying more clearance here but less there,The pipes are bent identical. They were laid out side by side & were dead on identical on all the pipes.
 
you are correct. it is a mease pipe. i just keep saying mine since i sent it to you and you used it as a model. its so i can say i can relate to the pipe not mine as i made it. sorry for the confusion

No I'm just trying to clear up the confusion on Mease down pipes & GBP. I worked on that with keith back in 2000. I also hear $600 for a dp. We sold them back in 2000 for $600 If I remember correctly.

Well, I have a original Mease 3” and wanted to share this, on "MY" set-up. :eek:
The car has energy suspension body bushings (16 months old), and H&R motor mounts.
In addition, the stock turbo mounting shield with just the added access hole for the turbo drain pipe is used for locating the turbine housing angle and surface position distance to AC box.

1-My pipe will not fit with the Poston PS header, unless one of the two is modified.
Add to that the ATR up-pipe and you have more troubles.
This was NOT a "bolt in and go" deal, at least not for me.

2-It also fits VERY close to the AC pipe. (Yes, the bend one)
Now I know some of you don’t need AC, but I do.
I had to remove the shield because (belief it or not), there was some contact that would set the KR gage off.
(Yes, the knock sensor was torqued "dry", at "14 ft/lb", with a "calibrated wrench" at "that target value")

3-My pipe got a dent from the UCA, because it “slipped” down from “Pressure/Heat/Vibration” and the slip joint.

4-The angle at the bottom of the pipe appears to be “off” for the exhaust, but that is the easy fix.
I know enough about the manufacturing of pipe bending, and jig welding, that there are always variances.
On a Hot Air with a 3" pipe, there is not much room period! This forces close tollerances, which cost $$$.

I am working on custom fitting this **** thing, while maintaining performance and serviceability.
(The car is apart, so I can’t take any pics :tongue:)

No, I am not upset with Mease or the pipe, just providing a summary of Hot Air Assembly experiences and things to watch for. :wink:
 
That just goes to show every car is different. I can dig through my pics and see what I have at different angles. I have postons headers and a ATR up-pipe.
 
don't have time to read all replys cause i'm headed out the door, have to get back to this later. i've just been really spoiled with my custom 2.5 dp is all. i'm using hr mount on left side, new stock mount on passs side, body bushings not new but excellent shape, and my 2.5 doesn't come close to hitting anything, period. i'm even using kirbans bushing heat shield and its got plenty of clearance. just being picky is all. may not have made up my mind by friday, but i'm still going to place a order for a couple other things i need from you this friday brian. hope your doing ok. also just saw thread on the 87 alumimum wheels. i'm still in for a set stock size if you go ahead with it
 
I paid a little north of 500 for the 3" mease pipe with a 3" dump and all the mounting hardware in 2003/2004... I never got to install it because my motor got toasted byt he previous owner and I didnt know it... turbo was shot, two pistons detonated, and the wrong oil pan on the engine!!!!!

The mease pipe looked amazing, and I was hooked on it because I bought Herb's (turboregal84) motor after his wreck (which was an amazing 12 sec set-up), and he had the t33c, mease pipe, ported out everything, original smc kit, and a few other odds and ends... I was trying to mirror his success, but college, then marriage, then baby put a few stops in those plans!!! lol


If the Gbody pipe is the same, then I should be able to expect the same performance right? like everyone is saying...EVERYTHING is harder with the bigger pipes... I have poston headers, and I dont remember 100%, but (I hope he chimes in), Herb also had the poston headers and his motor was awesome!!!!

I might still have a pic...
dang it... it is a different pipe... i dont know which one though???:confused:


here is the pic anyway!!!!

I have a Poston header on the passenger side with the 3"
D/P and there is no clearance problem with the header and
I also have the ATR uppipe. No fit problem except with the
heater box heat shield. So, with a 1987 turbo, ATR up pipe,
and the 3" D/P, the only clearance/fit pb. is with the heater
box heat shield on my car. A small pie cut in the D/P and
bend and reweld should solve it.
I plan on maybe some day doing this if I have time before
I give up on these cars.
