Tumble Generator Valves

[coyote]

Anyone replaced these little buggers with deletes?

I have come within half a bolt hole of doing so, but the mother f...ing piece of s..t bolt holes are different!

6 bolts from tgvs to manifold, 4 corners line up ... 2 middle bolts don't.

What's with that? Why change the bolt pattern on a manifold that's been the f.....g same for almost 20 years?!?

[senator]

weld the suckers up and why you have the die grinder handy, port and polish your inlet manifold.

[Boxer]

I thought SillySora had already done it?

... And no senator - you port and polish by ingesting sand through the intake

[coyote]

It seems everyone just slots out the holes on the manifold.

That's okay if you don't have a plastic manifold, but on ours you'd be slotting out the metal sleeve that that bolt comes down onto and basically crushing down onto plastic. I'm sure many do this, but I'm not going to.

Manifold has now gone back on with TGVs in place. If anyone has a set of TGVs *** that have been pulled off one of our cars *** then I will buy them from you and make up a set of deletes by removing the internals and plugging the holes. I'll then sell my old TGVs to the next person who wants to do the same.

I've been thinking about this as a possible to do. did you get any pics while the manifold was off? so you could point out where the holes were, etc.

I can see why people wanna delete em, they look like they'd be pretty restrictive when at full song!

Tony.

Are these the two holes your referring to?



If so, these could be plugged and re-drilled/tapped.

Let me know as I may be able to help you out.

Cheers,

With supporting mods yes, stock = not much point.

It pretty old technology with a new application. Toyota did a very similar thing in the 80,s on the 4AGE. I deleted mine, but again without supporting mods only increased induction noise and dropped torque

Yes they are mate.

Thanks, but the stockers are already back on the car.

The pictures don't even do justice to just how ugly they are.

[SillySora]

I got mine done. Apparently it is well worth it depending how far you go with the car.

Ah ok I thought they were just there for emissions. It's not like a variable length intake or anything...

YEah, nah - like the Toyota solution - more to control swirl and flow at partial throttle and low rpm, naturally this also manifests as emissions and economy benefits too
I think the Subarus have 3 positions though (could be wrong) wheras Toyota only had two. Obviously at full noise they do pose a restriction and turbulence

SillySora - I thought you had, but then there's not much you haven't modded is there?

[SillySora]

Yeah a lot of pro guys delete them. I can see why.
