After looking at my turbo I see that the exhaust side is a 4 bolt pattern to the downpipe. After seeing this I decided to look for some parts so a custom downpipe could be made. I remember reading that NismoPick said in order for a 3" pipe to fit between the 4 bolts then you have to use a 2 1/2" to 3" pipe like lifegaurdude did or something like that. Well, I found a flange that is 4 bolts for the T/3 and it has a 3 inch hole. This same place has stainless steel gaskets, also for the same flange...below are the pics. So what I am thinking is I take this flange and the O2 sensor bung to a muffler shop an I should be good right?

If that flange has the same bolt patern as the 280zx turbocharger, it should fit. You should ask the seller for the hole measurements and check them.

Isn't a 4 bolt T/3 a 4 bolt T/3?...or are there different 4 bolt patterens for the T/3?

NismoPick

There are several different bolt paterns.

I will have to look into this a bit more, let me ask you this Nismo...was your flange that you made, were the bolt holes the same distance...diagonally from corner to corner? Edit, I have seen 5 bolt 4 bolt and 3 bolt....all the 4 bolts I saw were the same distance, squared.

there are a poop load of t3 bolt patterns, i wish we used the 5 bolt one, can get a bigger down pipe and i could steal this 60 trim one off my buddies civic. lol.

NismoPick

No, the holes are closer from top to bottom, than side to side:

I dont think anyone sells a flange for our cars, im pretty sure of it? Everybody I know has had to have one machined.

thxone

Yeah, I have been going ***** to the wall trying to find one now....no luck....time for a rethink of my situation....perhaps just a new exhaust for now will do the trick. After all, there is actually nothing wrong with my stock downpipe so I am sure it will last a bit longer till NismoPick stops being a peckerhead and makes me one <---NismoPick

their are a couple wright ups on having 2 90degree bends compared to another design.

thxone

That one looks pretty nice....any chance you might know where I can get one already made or where one is for sale?

NismoPick

Hey... I got 4 car projects on my hands right now. I are bizzy!

NismoPick

That's pretty much my downpipe... I just made a flange, got a mandrel u bend, measured, fit, and welded.

260zturbo

z motorsport has some for sale. they get it from a guy who makes them. just as cheap to make your own. ss like mine is gonna be more but will last a little longer.

KTM200-280zxt

I have one that unlike any other that will bolt right onto a 280zx I was going to put on Ebay. SS 2.5" very nice welds.

NismoPick

But now you're not going to sell it? Are you teasing Thxone?

Last I heard, there was some kind of issue where they wouldn't clear the BW T5 transmission on the stock 280ZX turbo models.

You can buy the flange from the guy directly. It's a 2.5" flange. Look for "PeteZ downpipe" on google and he should be on the first page of the query. There is one seller on ebay who sells the correct 3" flange, but I can't remember their screen name offhand.

KTM200-280zxt

No. haha I was just hinting that if he really wants one I have one I might sell

yup, they dont work with our trannys, I had to have mine modified to fit.

I thought Pete went out of business?

PeteZ has some posts on different forums. I found no business website. It sounds like he was just making downpipes in his shop but very good quality ones for S30 cars. Nowhere did I see a 280ZX application.

I guess you can email him if you want. He sold the 240Z turbo.

KTM200-280zxt

Pete definately did make some good quality stuff well he was making them. He used my car to test fit his downpipes on a ZX and no he never made one for the ZX
Heres a picture after I modified mine to fit the ZXT

I believe Pete still makes flanges if you email him. I got mine from him even though he sold his 240. Excellent quality flange.
