Who has deleted EGR on 1FZFE?

[misfittoy]

@Toyo Boyo I'm going to go for the whole thing except for the block off plate near the intake. Unless removing the starter gets me better access. If not, I'm going to bolt it up like you did. Idk if I have a plug that will thread it but worse case ill use some coins and JB weld.

Ok so what's everyone doing with the fuel pressure regulator after deleting the VSV? I've seen it routed up to the manifold, but that seems like it would be giving constant vacuum. As I understand it that is just designed to increase fuel during startups?

I wouldn't have thought that needed to be messed with? On my 1995, it goes from FPR->little metal tube->side 1 of a VSV, which also has the atmospheric input-> side 2 of VSV-> another metal tube -> vacuum port on top of manifold. Doesn't involve the EGR VSV at all.
Judging from the layout, I'd say you're right about the cold startup use, it just lets the FPR equalize to amospheric for maximum pressure.

But then again, mine's a late 95 model even if they are both 1FZ-FEs.

You have to connect FPR vacuum hose to throttle body before throttle plate itself.

Next generation of 1fz (coils) doesn't have any vsv for FPR and EVAP

@Vasiliy that's interesting to know. It shows that It's still running through the VSV, however? I may take the VSV from under the intake and put it more inline like the coil version.

Negative, it doesn't have vsv, maybe photo was not enough clean.
That sensor with connector on intake plenum is 89421-20190 The manifold absolute pressure sensor (MAP sensor) it have vac hose that going to Gas filter. FPR and MAP vacuum hoses are holds with a clamp, so it looks like FPR still going to vsv, but is not.

Here is how I made it
Got little better MPG and no rich fuel smell at startup

I left mine on the engine but disabled it by capping the vacuum lines and shorted the temp sensor to prevent the CEL. Probably not as good as physically removing the whole system but only took 10 minutes.

Can you explain how you did this?

I'll vouch for this kit as well, really easy.

I removed the appropriate vac hose to disable the EGR about 10 years ago, with no issues.

However, I recently removed the upper part of the EGR and fitted a blanking plate.

I modified an old VW sump plug and fitted that to block the pipe. No issues, about 1,000 miles with this set up.

resurrecting an old thread for a simple question. The VW drain plug in the picture is perfect but does anyone happen to know the size and thread pitch? Probably M14 or M16 x 1.5 but that's a WAG on my part.
