ah ok, i thought maybe the solenoid was to restrict it to 5 from 7. ah well there goes that idea. will keep shopping for a 10psi r32 one. Any diagrams going around to disconnect it once i get the 32 one?

I think i did one a few pages back :down:

Hi!

There is no restrictor as such.

The actuator is subdued to the manifold pressure unless the car reaches 4500 rpm or so.

At this point the solenoid kicks in and reduces the pressure on the actuator, tricking the actuator into 'assuming' the boost is lower than actually is.

The actuator is a 5PSI type ..

Cheers,

Andrew

once you have the 10psi actuator the solinoids will be obsolite wont they ??

this mod has been around for a while now, how have peoples solenoids held up with being held open 100% of the time when it should normally be momentarily? any solenoid failures?

...I'll second that. Anyone?

Attention R34 owners

I have just done this mod without cutting or stripping any wires and it works.

1) Unplug the solenoid

2) Feed wire through the ecu plug side and reconnect plug. (see pics on post 231 on pg12) ignore warning as he had a different problem (see post 355 pg18)

3) Turn ignition on but not engine

4) R34's have an earthing strap from the engine that earths on the chassis just below the solenoid via a spade plug. Attach other end of wire here.

5) You will here the solenoid 'click'.

6) Drive around on high boost below 4500 revs.

Took less time to perform the mod than it did to write this post :P

Side note for those who want a switch for fuel economy. There are 3 pedals in the drivers side foot well. The far right one is the fuel economy switch. It's a good switch as it's progressive and not just an on/off switch :P

could some one please send me a pic of how the vac hoses are ment to be connected to the solenoid because mine has been bypassed and i want to connect it back up.

Here you go ...

Anyone with an R34 that has done this and felt a difference, before you did the mod, did you see the boost change at 4500 rpm? Using the stock gauge, once I hit max boost around 2800, it doesn't change until the redline.

Is this useless if you have an EBC?

Noobiest question Ive ever asked lol.

An EBC is basically a more advanced/adjustable version of the stock solenoid. Normally to fit a EBC the standard solenoid would be removed/disconnected.

if you unplug one of the hoses and block it it tricks the solenoid into keeping the wastegate closed for longer coz its getting an inaccurate reading,

by doing this i am running 11psi and only takes 30 seconds to do. seems pretty safe and dont get any boost spikes as far as i can tell

I had mine off and it definately did the same thing.. I ended up connecting it back up and doing it with the wire, but i am hitting 9 sometimes 10psi and i have only got a cat back and pod. Cant wait for my turbo back..

    • The MX5 has had some annoying rattles in both front doors over bumps So I installed fancy pants door bushings, which stopped all of the rattles with the windows up, but........with the windows down there was still rattles, so after some googling,  and a chat with MX5 Mania, I got some new door to glass weather seals, all the rattles, windows up, or down, are gone now Shout out to MX5 Mania, the weather seals were on sale, and when I head to Dural to pick the up they even fitted them for me for free I did see a "really" nice Blue NA sitting out front   and this Black NC PRHT that looked like it has sat in the sun for its whole life and never had a wash, the clear coat was non-existent, an it looked horrible, really horrible, but, it had a nice turbo kit with over 200kw, the thing went like a cut snake, bagging the rears through the gears and dosing like a champ 😍 But, as I've always stated, I am keeping my NC na, I'm happy with the current power the car makes In other news: MX5 Mania do a drive in drive out turbo kit, the only minor additional part recommended for boosting my car, as it sits now, is a oil cooler, and that bonnet vents are definitely required for track use Aftermarket version look a bit to "racecar" spec I wonder how Focus RS bonnet vents would look?????
    • Paint is only structural when applied to the outside of Chinese and Indian cars. Otherwise it should never be present between mechanical joints that were intended to be metal to metal. Pain slips, slides, cracks, compresses, and add thickness that wasn't intended to be there. It comes firmly under the category of "just no".
    • appreciated it thanks   There are threads on the adaptor. I rear re anodising but didn’t know it will reduce strength   re mating services needing to be flat/ not painted, why would that be? I am devastated as car been off for a year, fixed power steering then installed bm57 master cylinder and just before driving it this came up. So annoyed   worried and afraid to drive it, no fun caliper coming off
