Electronic Boost Controller

[crumac86]

Hey guys, I'm wondering if someone can hook me up with a cheap ebc for a 95 r33 gtst. I don't want to do the boost earth mod, just after a controller to run 9psi on stock turbo. Thanks Chris.

Grab yourself an R32 GTS-t 10psi actuator. Boost falls off to 9psi up top.

[crumac86]

Good idea but I want to rid of the 2 stage boost, as I understand it ebc is needed for that. Correct me if I'm wrong.

[Got a Pulsar]

Nah, you pull out the boost solenoid, replace the old actuator with the RB20 actuator, block the hose going to the BOV return pipe and drive away with 10psi.

[crumac86]

Can I do this without the rb20 actuator and run 7psi full time?

[Got a Pulsar]

Yes. Leave the RB25 Actuator and boost Solenoid in and Earth the solenoid for 7psi or do my Trick and run 2 solenoids in parallel and get 9-10psi.

It's in the Boost Mod Thread... But why don't you want to do the Boost Mod? It's good, safe and it works all for Free.

Great u know yr stuff, if I choose to earth out the solenoid is this reversible and if I choose to eventually get a ebc will I encounter problems because I have cut the wire?

[Got a Pulsar]

Wires can be reconnected. That particular wire will not affect anything else in any way, shape or form.

Just do it.

I have done the solenoid Earth, 2 solenoids Earthed and the Actuator. Each was better than the previous.

Also RB20 actuators on mates cars. It's easy as. But the Earthing is Free. Have a crack at it.

[crumac86]

Legend! So if I do this mod, and get a ebc down the track the original solenoid will have to be replaced?

[Got a Pulsar]

Yep. The EBC will have it's own.

[crumac86]

Thanks mate u have been a great help, one more quick one, with this earth mod is there really noticeable difference in low end power?

[Got a Pulsar]

Yes. It feels much better at low revs and instead of 5psi at 2500rpm you get 7psi.

Much nicer.

[crumac86]

OK you have sold me, I will have a go tomorrow night, well it really is a win win situation when you think about it. Cheers for all yr help mate!

[Got a Pulsar]

You will not regret it.

other than, it will give you a hunger for more of that "untapped power potential"...

Please let us know how it turns out.

[crumac86]

Will do

[Got a Pulsar]

Don't forget, you don't have to "Cut" the wire, just strip back some of the plastic insulation and tap a wire into it there, then Earth it.

Do it to the Solenoid not the loom.

Simples.

Hi mate, completed the mod, went for a drive and wow, 1st has wheel spin now and 2nd feels more punch down low. Great little mod. I think I need some new coil packs as I have more hesitation in the higher revs now but works a treat. Or I need to regap the plugs as they are 1.1, boost is fun :]

Hey rob, i'm still curious as to what difference there is with earthing the solenoid compared to bypassing it completely.?

Excellent, Gap them to 0.8mm and see how it goes. (Yes Boost IS Fun. )

Earthing it is 7psi all the time, Bypassing it you will get Actuator pressure only.

(5psi stock) or as you (and I) have done, 10psi.

If for some silly reason you had the R32 actuator and the solenoid earthed and connected, you would get 12psi and it would be crap because of the ECU freaking out due to Too Much Boost / Air.

If either of you bought an SAFC and had that tuned, you would be amazed how much more power you get.

(even though in the scheme of things it's not very much compared to the big boys 20psi+ etc.)

[Sklyn]

ahh ok, got it.. =)

So safc, more power from same boost? cos any more boost and i need new turbo to go with it, then theres a whole new ball game =)
