1JZ bottleneck found

[Nucleon]

Hi guys, I've never read about this so maybe this could be new to you. I was just replacing the rubber hoses that connect the T-Intake pipe with the turbo intake pipes.

The stock hose is a bilayer hose and with time passing by the inner layer caved in, because of the vacuum in this area. Since this will happen to new Toyota hoses too, I decided to replace them with 50mm id radiator hose.

Some pics:


Left ist the old hose and right the same new from Toyota.

I noticed you have what looks to be either ridiculously good condition original exhaust manifold studs or brand new stock studs. If they are indeed new studs, where did you get them and/or do you have a Toyota part number for them? Thanks a bunch.

Toyota part number is 90116-10169 for the studs and 90179-10094 for the nuts. Be sure to have new manifold gaskets.
