Title: HKS wastegate exit V-band clamp - sizes, options, dealers!?
Post by: lockwood77 on June 16, 2011, 01:46:39 PM
Does anybody know what size or name of clamp and associated parts I need/are available for an HKS wastegate (I\'m assuming it\'s a GT or GTII)?

I\'m going to have it plumbed in to the exhaust (or separately silenced - apparently you retain more power with a separate silencer, but the risk is it\'s louder), but the custom exhaust guys need at least the clamp. The outer diameter is 70mm, internal seems about 53mm, so I\'m thinking maybe the 50mm HKS wastegate clamp I\'ve seen here is the one? http://www.horsepowerfreaks.com/partdetails/HKS/Turbos/Turbo_Flanges/Square_4-Bolt_to_V-Band/4761

The guys were also saying that it needs an olive to mate up - you can see the internal bit of the flange has a lip. They can have this made up, but if something exists (like that thing on Horsepower Freaks?), that would be an easier option. Can you get the flanges or other fittings off the shelf?

Has anyone had to do this stuff before - any tips!?

Hi, you should be able to buy all you need through Dan at sumo power
Genuine hks parts, check the hks USA web site for the bits you need then order from sumo power.

Cheers, will give them a go, I did look at HKS USA but it wasn\'t terribly clear which bits I needed (to me anyway!)

Awesome, thanks. Guessing the one I need will be AK017 50mm from my measurements. Best double-check whether it\'s a GT or GTII as well, seeing as they list the clamps for each separately! :)

Think I\'ve answered my own question on that one - GT is silver, GTII annodized purple:

http://www.hksusa.com/products/?id=697 - GT

http://www.nengun.com/hks/gt-ii-wastegat - GTII

So I have the GT - clearly a different design never mind the colour. Shopping time!

Bugger, HKS are out of the flange here and in the USA. Anyone know of anything else that fits (one US vendor has suggested a Vibrant flange)?

Did you get anywhere with finding a source?
 
I was facing a similar problem with HKS wastegates, screamer pipes v-bands and so on and thought these guys might be able to help:

Haven\'t contacted them myself yet because my plans have been slightly changed by a popped apex seal ... :(

Yeah, got the clamp from Sumo Power no problem, the flange itself is a different matter - I had mine custom made by the exhaust place in the end, only cost £50 or something, cheaper than buying one! They\'re discontinued for the GT wastegate anyway, nobody here or in the States had one.
