the tII manifold i got didnt have it. i guess i can just leave that waqy to block it off huh?

 

It should have it, there's no need to block it because N/A housings are plugged

 

Coolant seal, something oil related I recall, non-clearanced side seals, etc. All things he forgot to check or be careful with during the original build, but I think he learned his lesson.

Sometimes learning a lesson takes a few failures. I hope whenever he builds an engine in the future he knows to be extra careful now heh.

 

The only TII parts on my car are the turbo and manifold.

Originally I used the NA ECU, and only the TII injectors, turbo and manifold.

Now I will be running the Microtech LT-8, and basically everything else custom. Block is still NA, NA rotors, NA everything.

 

i was talking about the hole on the bottom of the primary port. here's the pic again where i circled the hole in question

 

Yah, the type of setup Aaron did is not like what felix is trying to do, and in fact never was since he continued to use his n/a ecu and wiring. His is pretty much all custom except for the internals to the engine. Not really in the same league.

 

Oooh, haha didn't even look that far!

 

I was under the impression that to be port matched correctly that that hole had to be filled in with a metal putty of some sort and then ported down as well to cover the whole secondary port.

 

heh heh...fo'gedaboudit..... i was told that those holes on the n/a front and rear plates were there for emmissions reasons. is that true?

 

The port doesn't need to go down much at all, only a tiny bit. The hole you're thinking of is probably the top one maybe? If you look at the port closely, you can see that above each of the left/right port matched runners, there used to be similar holes that were filled in a ported. That part is definitely needed.

I've done this myself, it really sucks and takes forever to do a good job. That one Felix has was done fairly average I'd say. Whoever ported it could've spent more time grinding down the back edge of the port matched outer runners to make the transition smoother. If you look inside you can see that it has a very abrupt edge :| I made sure to spend extra time on mine grinding this down as much as I possibly could to give it the same smooth transition that it has stock.

 

That port is for the EGR valve on the Tii manifolds. The na egr valve is on the block instead of the LIM. Thats why I got two egr blockoff plates on mine.

 

ok...so i dont need to port the hole. how thick do you think the walls are at the back edge of the runners?
