Hello everyone! Well I ordered a MBC last week and I'd like to install it over the weekend. Did a regular search and an advanced search on how to install the MBC on my GTE VVT-I and have come up with nothing solid. A couple of members on here have directed my to a few LINKS and after viewing them im kind of at a loss, it looks like they are on the 1st gen aristo or the MKIV supra. I've installed MBC's on single turbo cars before but on this set up it seems a bit more complicated. If someone out there has installed one on the stock twins and would like to give me some guidance I'd appreciate it very much.

And once installed and working Ill take good clear picture and include them back on my build thread.

 

Yeah single turbo mbc is a bit simpler, but the vsv routing is the same on the vvti/non vvti so the diagrams still apply from a mkiv/147..

 

ever sort it out ??

 

So it looks like you only need one pressure source from one of the turbos and just like on a single, you T in between it and the waste gate, only you are going to both waste-gates.
