hey i need some 2 3/4'' ID 3'' OD intercooler piping couplings and i found them @ rx7store.net but i was wondering if any place around me would have them like carquest or autozone or maybe even home depot

does anyone know?

 

i searched locally and never found them (including home depot and lowes). i ended up going to turbohoses.com.

 

2 3/4" is an odd size coupler, you'll find 2" and 3" but no 2 3/4" locally, unless you have a perf. shop close by. Best bet is like Legal-Z said either turbohoses.com or hosetechniques.com. These guys make reinforced hose couplers that won't disintegrate when you boost and when they get hot.

Question regarding the intercooler hoses shown here: http://www.turbohoses.com/Rx7%20Twin%20Turbo.htm

What is the difference (or why) go with the "hump" hoses vs. the standard hoses?

I know some of the hard intercooler piping kits come with the hump hoses (HKS for example), but is there an advantage to hump hoses?

And if you have hump hoses, can you replace them with standard hoses?

Thanks,

Mike
