Tips on things to replace after engine removal

g.scov · 05-31-2010, 04:27 PM

thanks mirage. after some research last night I came to the same conclusion. both serve a purpose. I need to figure out how the canister is supposed to be hooked up.

one a different note. if I plan on making some upgrades to the engine are there any aftermarket ECU's that plug directly into the existing wiring harness?

Here's a pic of the engine bay and charcoal cannister vacuum line routing for it, courtesy of a serious Supra enthusiast and his website...

As for standalones and such, one of the members on here who are into such things will need to help you out with that. I have zero experience with them.

I 've heard mixed views on the the erg removal. I put mine back on when I did my hg but many people I have talked to with mk3s run without them by just running higher octane gas. I've heard one problem is that the egr can crack and leak so that may also be a reason to remove it. And with the evap canister, you can always go with a smaller one from another car to open up some space in the engine bay.

this is how the back of the engine looked when I pulled it. I'm thinking someone before me deleted the EGR, albeit very poorly. Can anyone confirm that these are indeed the EGR holes or is this something else? One way or another something is missing.

Yeah someone already took the egr out. The two ports that have to be blocked off are on the intake where it is blocked off and right by the #6 exhaust port. The other ones don't really matter.

so what all do I need to buy to put it back on?

You need all of the egr and the egr cooler plate for the back of the cyl head. I would just leave it go for now and run premium in it for now.
