manifold questions
 

couple questions and im not a newb screw you flamers!

i have looked over a few posts in here but im lacking a little knowledge.

1. when buying SS 90's should i get long turn or short turn? i see anywhere from 12-15 bends would i be safe with buying 14?

2. waste gate bends. im going 1.5" in the main runners. should i jsut run it on the wastegate stub also or just some 1.25"?

3. what is the difference between sch40 and sch10. i work around sch40 pvc all day. but not sch10. is the sch10 thicker or thinner? like is it off of teh same theorey as wire/steel gauge. where teh smaller number ti larger?

4. where can i get a nice exhaust flange from? i have emailed a couple places off line and no response. i need an SS exhaust flange for a mazda 1.8L. i also need a t3 flange but that is an ebay search away.


thanks in advance bitchs!

1. Long sweep is the most common. We need more information on the type of manifold you want to make.
2. keep them the same size, you definately don't want to restrict your WG at all.
3. Sch 40 is thicker. Sch 10 is fine for a turbo manifold, however.
4. For exhaust flanges, I'd go to BMC. I'm fairly sure they make a flange for you. You could try LSD too.

oops i thought i had all the bases covers.

1. ramhorn.
2. i know the restriction issues just wanted to double check.
3. good to know. i will probly go 10 and build soem cool webbing style supports.
4. i will make a couple more email/phonecalls.

thanks

Re: manifold questions
 

98% of the time we sell the long radius 90° elbows to customers who are making manifolds. Short radius 90’s are great when you need a really tight radius bend but are extremely expensive (read: not always the most cost effective method).

Sch10 is the thinner of the two.
For reference:
1.5" sch10 = 1.9" OD x .109" wall
1.5" sch40 = 1.9" OD x .145" wall

If you click on the individual item in question on our site it will show you a little table with the sizes and specs for each product.
