Vaccum hose splification pro/cons? Plus one question
Thread title pretty much explains what i'm looking for here. I'm just wondering about the benefits or lack of benefits to simplfiying the vaccum hose system. I've done a fairly brief search, but haven't quite found out exactly what i'd like to know.
If someone could please post the pros and cons of this procedure and maybe even link me to somewhere that could explain a step by step way of doing it? Pretty simple I know, but is there more to it than just following a simplfied hose diagram? (Which I do have)
And one last thing... with the UIM manifold and everything else taken apart, what other jobs do you reccomend while doing the hoses? Plugs/wires are a given, but i've read a little bit about replacing the FPD and FPR while you're at it.. my car is at 80,000km and i'm thinking it should be done. (I don't know if the previous owner did it or not)
Thanks in advance!

IMHO even with your low mileage, I'd replace the FPR for sure, but from my search and reading, I didn't see many accounts of FPR failures. If the FPR does go bad, I don't see it leaking like the FPD. I'm also replacing fuel lines with new, and the OMP lines with stainless. But you can also construct your own OMP lines from better aftermarket material ( https://www.rx7club.com/2nd-gen-archive-72/rebuilding-omp-oil-injection-lines-348068/ ). If your getting down to the fuel rail, consider injector testing and cleaning.

First,
Simplified sequential does not make the turbo control part of the rats nest any different. You're only removing emissions stuff. Removing emissions stuff will not do anything to fix boost issues or reduce the likelihood of developing boost issues. However, working on the car with less emissions stuff is definitely easier.
If your goal is to fix a boost problem, you can change to non-sequential or dig in and test/troubleshoot your solenoids/actuators/tanks.

You could do the job without block off plates, but leaving all the emissions equipment in there but unplugged would greatly reduce any benefits to doing the work in the first place.
Are you just looking to make things easier to work on? Do you have a boost problem? Whats your reason for doing this? If you want to make things easier to work on I relocated my coils to where the cruise control would be, that cleaned up alot in there as well!

Well for me, a reliable car with clean looks is the name of the game. I'd like to clean up my engine bay. I haven't read much about relocating the coils but i'd be intrested if you could tell me more about it.
I don't have any boost issues, but like I said.. reliablity and clean looks are both very important to me. I'm doing a vac hose job one way or another, i'd just like to make the most of my time while the UIM is off. When you remove the emissions equipment with block off plates, are you supposed to pull out the solenoids for the emissions stuff?

If you are not having boost issues and are just looking to replace the vac hoses pre-emptively go for it. Might want to consider replacing the hoses one by one. The system is actually pretty reliable so long as a vac hose doesn't rip or pop off and the solenoids are in good working order. If you break a solenoid nipple (like many people do during a vac hose job), replace it with a new one.
In 6 years of ownership, this week was the first time I've ever had to remove my UIM. And it was to replace the throttle body hose, not something turbo control /vacuum related.
I'd like to add two more things to the "while you are down there list":
- replace Fuel Pulsation Dampener
- remove injectors and have them cleaned
- check your oil injector squirters and OMP lines
- replace the fuel lines and hose clamps with new OEM parts
- replace the coolant lines that are accessible while you are down there.

Nice, that kit looks pretty sweet. Was wondering if it'd fit on a RHD car though. Don't really see it being a problem but I figured i'd ask.
Still a little confused about the simplifacation process, are you supposed to just remove the hoses not shown in this diagram? http://www.turborx7.com/images/turbo...simplified.jpg And then put in the set of block off plates?
Thanks again for all the help!
