Hi Everyone I want to share my simplified sequential setup I have been working on this week. I also figured out what i think is a really sweet place for the solenoids, hopefully it works out! Some feedback would be cool (good\bad) trust me I dont get my feelings hurt, I just like fixing problems before they happen.

Looks good. What solenoids did you use?

Get that back together and let us know how she performs!

Seems like a good idea, have you checked for clearance with the UIM and throttle body installed?

I like the way it looks hopefully it works out for you.

I am useing stock solenoids for now, just untill I can get my hands on some better ones.

RX7FAB

Yeah everything seems to clear fine pics 2 & 3 are with the UIM and coils on. I Should be finishing this thing up today as long as my fuel dampner shows up!! I will let everyone know how it runs if it gets finished. Thanks for the feedback!!

IMO, I wouldn't locate the solenoids there. It's called a firewall for a reason. I don't think that area is going to be much cooler than under the UIM as you'll have the heat absorbed by the firewall and the heat radiating up from the transmission.

You probably would be better off keeping the solenoids under the UIM and then using some heat tape under them to help isolate them from the engine heat. Then again, if you goal is just easier access to them, then that's a different story.

I tend to disagree. Air flow and heat is trapped under the UIM, at least the firewall has some air flow.

Trapped? I wouldn't agree with "trapped", it's not a sealed box. As I mentioned, this is not something I would do as I would prefer to provide a heat buffer where the solenoids are located under the UIM. Reducing the heat absorbed from the radiant engine heat will add enough longevity to solenoids without having wires and vacuum tubes strung all over the engine bay.

wouldnt it absorb more heat sitting right above the engine and under the UIM?? almost like an oven.... if anyone has a digital thermometer just let your car idle for a bit and check both temps.... then do a couple drive-bys and check the temps again....

Again, you are missing what I wrote. I mentioned using heat shielding around the solenoids under the UIM. It's been done before and it works.

RX7FAB

Thats what I was thinking, plus this will let me clearly see any problems under the UIM without removing it. Also this will hide 90% of the vaccume lines and solenoids, so far it is looking super clean almost as clean as a single setup!

RX7FAB

Once the car is running I will hit the solenoids with a thermo gun and compare to the stock location that shoud clear things up either way.

You could just shield them where they are right now. Just insulate them from the firewall as well somehow.

I moved my simplified solenoid rack behind the ABS.



turbo control x 2, charge control, charge relief, and purge control. I'm debating on whether to eliminate the purge control solenoid altogether but it fits in here for now. The pre-turbo/wastegate lines are driven by MBC's located near the primary turbo inlet.

Just a guess, but a simple heat shield should help with the UIM location. I worry a little about the movement of the motor vs the firewall as it may come too close to the rack.

Witch simplified vacume diagram are you using in your upgrade?
Looks anyway very nice

Finally after all the moving this week i finished up the car, it is running better then ever no more 3k hesitation big bonus! I am very happy with how everything turned out and I was very supprised how well it runs on the factory computer. Just thought I would let everyone know how its running. Thanks for all the response.

Very neat. I like it.

Would you know if this system is adaptable to a late model JDM with the solenoid box?
