ITB Install Progress and Questions
 

Hi,

I have completed bank 1 install of my ITB EFI project and I have plumbed the fuel filter to bank 1 line. I'm taking this slow and steady ...

I do however have a couple of questions:

1. I ended up having to shave down the insulators as they wouldn't fit in the engine shroud. Is that a common thing?
2. Do I need to put in a catch-can for the oil? Any suggestions for which one?
3. Any suggestions for removing the existing wiring loom unused components? Can I just cut them off the old loom?
4. In the right hand, upper side of the engine bay is something that has a couple of connectors off it, can I eliminate those connectors? What is that thing for?

Thanks,

#1 I cut the engine shroud.
#2 I put a small filter, at the oil filler.
#3 I cut them back covered the raw end with heat shrink, the recovered with wire cover.
#4 the black thing , I think is a charcoal canister, my part is long gone.

Agree with ^IS300.

1. I would have trimmed the shroud, fine at this point in the mod journey of this vehicle.
2. You can put a catch can or small filter. Small filter is cheaper obviously. I have a catch can on my carb 2.7 and nothing gets in it, I'm not tracking the car though.
3. Because of the age of the harness, I would say it's OK to cut. I methodically removed wires from mine without cutting, but to what end? the wires were getting hard and really a new harness would be better. Timmy2 (dennis) makes new custom harnesses if yours is crispy. The worst part is usually by the alternator those wires get cooked.

A small filter works great and like Duane said, unless you’re tracking the car the odds of vomiting oil everywhere are really small- even if you rally the car and drive it hard.

For the amount of time you’ll spend cutting open the harness, pulling wires and remaking connections, it’s probably just best to get a new one. Not only is is so much cleaner, you know it’s going to work really well.

That said, I just spent a day pulling unused wires from my main harness and it was a bear… yes, I feel better about not having useless wires in the car but there’s no real functional benefit and to a degree, now I can’t repurpose those wires in the future if ever I want to add something. But so it goes.

A filter is probably fine for the breather. If it does puke some oil though, like if you drive it hard or the engine develops some blow-by, a filter won't stop it. A catch can is a safer option. (If you do the catch can, make sure you vent it with a filter.)

Also, if you run heat, you'll want to route the fumes into the intake- I had mine open for a while and on long, cold drives with the heat on I'd feel like I was going to asphyxiate.

Are the insulators needed? I've found posts saying yes and no.

For the breather, I'd like to use an old school metal air filter housing from a carb setup. I just bought an old one. I think it will fit my PMO EFI setup without too much trouble. We'll see.
