1G Dumbest idea ever?

Anyone ever make hard intake pipe from PVC?

Been trying to find a recirculating intake pipe for my '91 GST that actually has a vacuum nipple for for the crankcase vent.


I have that one but no vent, and I was a dumbass and powder coated the inside.

Broken plastic through a turbo can end a good day very quickly.

Please do not. PVC has a melting point around 175*F. Though that might seem high enough to survive, it is in a confined space and it can heat soak causing deformation, melting or gas emissions, all of which are toxic organic compounds.

Use a different material, PVC is not one I recommend inside an engine bay.

Pvc begins to loose rigidity Above 73*F.. At 100*F it's only 70% as strong. Melting point is 170*F.. & it can emit chlorine gas above 100*F. Not something I'd be safe with or recommend but it's possible.

You can get a metal intake on eBay for $80 with Couplers and filter. Way better option.

I've been googling and haven't found much that fits a stock 1g+maf. Reasonably priced anyway.

OK, no PVC. Seriously wanna eliminate my stock intake but want to keep the vent proper.

Why don't you have one welded on? I had to do that to my stm intake. Just had a bung weld in with a screw in barb fitting and it works great.

Never do anything on a car with pvc, it's a horrible idea for everything. Just wait for the part you looking for to pop up and do it right.

He powder coated the inside and outside. No impossible but not really feasible to weld anymore.

I too had a hard time finding. 1g intake, so I made mine out of a 3", 45* pipe, and a 45* 2.25"->3" silicone coupler. Had to alumaweld a recirculation fitting on, but it looks decent and fits good.

All in all I think I have about $30 into it. There's a pic in my build thread of it out and installed

 

[Freddyk79]

I don't have access to aluminum welding really. And yea, I'd have to grind the paint off.

I found this injen pipe available, will this fit my 1g with stock maf? Looks a Lil bit long compared to the other ones I've seen.

Only on tuners would someone try and make an intake out of pvc.... .
Made my Friday.

 

[Freddyk79]

Oh I never tried, that's why I titled this thread accordingly

Just run the stock pipe. If your on a 1gmaf you don't need anything else.

I have an intake pipe for sale cheaper than building a pvc pipe . Check you PM.

I'm sure if you put up a wanted ad in classifieds, you could find one at a decent price. ^^^^^^ There you go, he has one. But I definitely wouldn't do pvc.
