BV43A chra into BV43

Mikey-s · November 14th, 2019, 10:00

Hi, I have a BV43 170hp BRD turbo to go on my A4 AFN. I'm going to replace the chra but I was reading the BV43A chra is a direct replacement and will help with faster spool up. I can get the below chra from Melett in the UK, can anyone confirm this is the one that will fit my BV43? https://www.turborebuild.co.uk/websh...io-20-TDI.html

Just buy a genuine used bv43a turbo, they are cheap... Yellow tag is what you want... That one you've linked in the post looks like it has a cast compressor wheel, the genuine bv43a has a 6+ 6 blade billet alloy compressor wheel...you want the whole turbo as the actuator swaps with the housings- saves messing about with adjusting actuators...

It was one of your posts that got me thinking of the BV43A chra. The BV43A has a different compressor outlet, or at least I think it does, plus I already have the BV43. I think that photo is just generic, I'm more after the part number confirmation. Thanks for your help.

Out of curiosity, what car do you have ? Any mods on it ?

Yep, just as i mentioned in that post, you take the PD turbo and swap in the whole cartridge from CR turbo into the pd housings...didnt i make that clear enough ? I would be very surprised i the Mellet Chra does have billet compressor on it, they build replacements so not necessarily buy replacement parts from Borg Warner/KKK ! From actual experience, mellet pictures on ebay are actual pics for the items they sell so returns are minimal !

Found this pic from another Melett dealer which shows a billet impeller.

Then it looks like the right part ! I was stressing on using genuine due to the fact that you dont need to adjust the actuator with another turbo as its bolted to the chra vnt arm...

Turborebuild.co.uk who are a Melett dealer are fairly close to home, I'll give them a call later to confirm this has the billet wheel.

So it's confirmed the Melett BV43A chra does have the billet wheel, see the quote from Turborebuild.co.uk. I'll get my turbo over to them to see if they can fit one and setup the stop screw and actuator.

The genuine kkk bv43a chra fits into bv43 housings without fouling on the housings- i have used quite a few along the years...

Ok perfect, thanks for the confirmation.
