up pipe

[decarlo sloan]

would an atr up pipe make a difference with a te60 and mpe 3inch dp

In my opinion it would not make a difference as long as your current uppipe is not leaking. Brad

 

[decarlo sloan]

it is leaking

You have a fire hazard. I would not drive the car until you replace it. The ATR uppipe would be a good choice. I had bad luck with the one from Poston-didn't fit. I picked up a nice used stock one from the Parts wanted section. Brad

If its leaking you will notice a huge difference in spool and HP, espeically with that turbo.

I have the ATR up pipe and like it very much. And even if your up pipe was not leaking, I think it would help a little being mandrel bent, flow is everything.

While we're on the subject, has anyone found a good lead donut gasket to seal the up pipe that they have a part number for? I have poston headers and an ATR up pipe, and I use the 85006 Engine Seal gasket with decent results, but the inner diameter is about 1/4" smaller than the up pipe, and I don't like the restriction.

I got the same setup. Poston headers and ATR up pipe.

I used no gasket, and ultra high temp sealer (orange stuff), worked great and never leaked, but there may be a better way.

i mocked up doing it without the gasket the other night, but the angles just didn't seem to jive. could be just my setup, not sure but next time i will make a more serious attempt without a gasket just for the hell of it. the only good thing about the location is that it is post Oxygen sensor, so i doubt it would throw off the mixture, probably just affects spool.

The ATR uppipe should give more power even if yours wansn't leaking. One look at the stock uppipe without the wrapping will show that it necks down to about 1.5" in places plus has the flex joint.

i agree, its just that the gasket i am using is 1/4" smaller than the up pipe, and i thought that might pose a restriction. do you have yours welded?

 

[cool 84]

Are you talking about the gasket from the header to uppipe or uppipe to turbo? Since I have the KB headers which don't have the donut gasket, I used the stock ceramic gasket that originally went between the uppipe and turbo. I layed it flat side on the header and donut side to the uppipe with a little RTV. I ground a little out to make it the same size as the uppipe. It's worked better than any "aftermarket" gasket I've found.

i see. yeah i was referring to the header to up pipe.
