Bov Causing Shudder

Ok finally have the Greddy FV BOV fitted, but wasn't straight forward.

First Nengun have kept me hangin for 4 weeks so purchased a local Subaru one, which is longer with the rubber o-rings.

I kept the Nissan one for a jig, clamped the new one to it with a 30mm pipe holding them symmetrical.

Drilled through to correct the mounting bolt centres then dry fitted.

Had to keep reaming to get them perfect.

The adapter plate was too big and hits the intake pipe on the inside edge, so had to grind out a bit off the edge to get it to centre.

Luckily this adapter has rubber o-ring seals on both sides otherwise too much of the flat surface was compromised.

I had to grind a chamfer all the way to the o-ring

The Nengun adapter has a cut out on one side and might fit better.

This BOV has a 40mm dia valve as opposed to the 22mm Turbosmart.

Finally got the adapter fitted, then the BOV doesn't seat as it hit the OEM mounting bolts.

The heads are too big, so had to grind off one edge plus a tad off the bov itself.

Started it up, and idles beautifully..

Finally you fitted it.

Just curious why your greddy bov doesn't come with adapter? I know greddy do bolt on bov for M35 and the adapter should be come with bov together in one package.

Hey quespionage- that blue vacuum hose. It's not the spongey redline performance stuff that you can pinch and cut off airflow to is it? I'm assuming it's at least 3mm id from the pipe... just asking

na, it say Samco on it.

4mm id , feels ok.

I replaced the split stock line to the boost-t with the 1 mm restrictor in it.

yep you can, but its around $400 and only available overseas.

I picked up the bov for $150 delivered + $32 for adapter

Mmm, got boost leak so will need to use gasket sealant.

Still haven't tested it out properly as the weather is so bad .

Got more pigeon sound though than the Turbosmart with the soft spring

Why have you invested so much time in a poorly fitting, and obviously poorly built knockoff BOV?

BOV looks genuine.

Didn't know it was going to be a bitch to fit with bolts clashing and clearances.

I don't see it a waste of time as I enjoy tinkering.

Especially if it works better than the Turbosmart.
