I need uprated Solenoids to run my car in seq with my BNR's...does anyone know where i can get some higher psi rated solenoids?

Thanks

Search for Saxyman's upgraded set.

You may have an easier time (less work to install too) if you install a pressure regulator on the pressure chamber. That will remove the need for an uprated solenoid.

Saxyman's set doesnt include the turbo precontrol and turbo control solenoids, so no good for rixio.

Huh...? Sorry think of me as a blonde and please elaborate...

Bob im sure Rob did mention those. He said it included all the ones i need to run Seq Twins...will check with him tmrw though

Saxymans kit replaces the solenoids under the inlet fanny mould.

there are two more that bolt to the front of the fannymould that the kit doesnt replace (to my knowledge)

these will need replacing too i should imagine for the BNRs, ask GoodfellaFD3s what setup he ran when he has BNRs - he ran the stage 3's at quite high pressures so probably your best bet to talk to him.

if saxymans kit does include the solenoids im talking about please send him my way, iwant some!

Rixio_Scon

Ah...get ya...he can make them cos he manufactures them all himself. Il give him a buzz again tmrw and ask...infact il try now and see if hes still around...

The precontrol and wastegate solenoids aren't really affected by higher boost pressures because anyone running higher boost has taken them out and is using an adjustable boost controller instead.

The only reasons for an uprated solenoid are 1) ability to consistently release under higher pressure, which only applies to the turbo control pressure solenoid (all the rest operate in vacuum, which doesn't change with increased boost) and 2) more reliable operation over years of service.

If reliability is your big concern, you can buy new Mazda solenoids. The solenoid set produced by Saxyman is certainly going to last longer if you can find a set and don't mind the extra fitment.

If consistent operation at higher boost is the issue, install an aftermarket boost controller because you need it and then add a pressure regulator to the pressure tank. This will keep the turbo control pressure solenoid from running under excessive loads.

Just had a word with Rob...then my battery died...

He can do those 2 extra Solenoids for an extra $100

According to my engine builder...he said the PFC is enough to control boost on the twins its only when going single you need an aftermarket boost controller. Now i actually had a HKS Boost Controller fitted which he removed before i took delivery after the engine rebuild.

I did have a conversation about this with a friend only 2 days ago and we both agreed that the PFC cant "Activley" controll boost pressure. So the only reason he would have removed it is for me not upping the boost & blowing it under warranty...

What do you mean by "Pressure Regulator to the pressure tank" British terminoligy and American is slightley different

Here you go Bob...Rob just emailed me

"As far as the additional 2 solenoids (wastegate and precontrol): I do have these available for an additional $100 US. They do require a little bit more effort to install. However, as I mentioned over the phone, the stock WG/PC solenoids are actually fairly reliable, and in my opinion, do not require upgrading. My personal recommendation is to simply save the extra $100, and just stick with the standard 4 solenoid kit. You can always order the additional WG/PC solenoids from me at a later date if you need them."

Carl,

The basic kit does not include the Precontrol/Wastegate solenoids. But I still can offer these to anyone that wants them. The solenoids that I offer are custom, and I can configure them to do pretty much anything you need.

The stock WG/PC solenoids are of a different design than the other stock solenoids (they have a different central operator and internals). In addition, they are not located underneath the UIM, and are not subject to nearly as much heat as the others. Hence, the stock WG/PC are actually fairly reliable (save for the issues of broken nipples), and have no need to be upgraded in most cases.

Dave,

Many people (not all) running an adjustable boost controller still use the PC solenoid, and simply install the new boost controller in the wastegate lines.


Not just the TCA(pressure) solenoid operates with pressure. The CCA and CRV also both use pressure from the secondary charge pipe to assist their operation.

Dave, that's kind of a clever idea - do you run a regulator on your pressure chamber? Do you know of a particular one that works well for this application?

That's true.

But IIRC the turbo control pressure solenoid is the only one operating in a manner where the spring has to release against the boost pressure. Therefore it's the one that is most likely to have problems due to elevated boost.

Care to comment on this?

I haven't done it myself because I'm running stock boost.

You can use solenoids from 99 spec fd3s this one in black box.
Also you will need the wiring connectors of 99 harness because is different from 92 fd3s.
Work perfect never stack.And is mazda upgrade
