I am having a few problems after installation.

Im finding that when coming onto boost it spikes 2psi over the desired limit and then sits back on the limit its set to..

I.e aiming for 12psi, as it will fullboost to 14psi and then back off to 12psi pretty much immediately after and for the rest of the rev range

My one has no holes in it.

There are no restrictors in the hoses to and from the wastegate and compressor housing.

any idea's guys?

^^ thats kinda just what they do - You'll find that most people using this controller including myself find that boost tapers off toward redline i.e might hit 12 early on very breifly but then slowly tapers off to 10psi by redline. They still hold it pretty well for a $30 item. Any more accurate and you'll need to consider an ebc, which even vary a little bit to.

Can you use this controller to lower the boost as well? i mean is it hard to change the boost level every time as in with an electronic controller? it would be useful for when you might want to drive a bit economically

Also is it stil around $32 delivered? pretty old thread

They're still for sale at that price, i have one and love it, boost snaps on so quick

IMO, you shouldn't need to lower boost ever, if you bought a skyline to save fuel, i know smarter people in pre-school, but if it's really necessary just loosen your foot, drive off boost as much as you can, its not hard.

i just ordered mine as well, now i got to wait :)

hope it works like pple say

btw

do new ones come with hole or without?

Got mine last week, there is a hole.

Should i set mine at 9psi? I have a stock standard S2 Stagea (RB25DET NEO)

REALLY don't want a spike to blow the turbo :D

9 psi even with a spike (these dont spike very much) wont blow your turbo thats deifinately a safe level. Inlet temps might ^ a bit with the stock cooler but should be fine.

He must have gone back to putting the hole in, cos when i bought mine at the start of the year it had no hole and i had to drill it in.

Cheers, will do that then.

Can't remember which is better, i think with hole is better for high boost or something like that. Probably much of a muchness really.

Just hooked this up this morning and my oh my, unbelievable how quickly boost starts coming in now. It starts building up from less then 2000rpm! Currently set at 7psi, seems to hold well enough with no spiking. Will try 10psi later. I tried to dial it down to 5psi with no success, boost went more then 7psi everytime i loosened it too much. Must be the spring not reaching the ends and not pushing the ball bearing, resulting in leakage... or something. Not complaining, with boost coming in so early, i reckon you actually save fuel because you require less pedal to the metal :laughing-smiley-014:

Installation was a breeze (S2 Stagea RB25DET Neo) as long as you know which hoses to disconnect.

I'm havin problems with mine fellas, even setting it as far out as possible(keeping tension on the spring), I'm running rediculous boost(my FCD keeps cutting fuel off at about 14/16psi) but I only want to run 12! Any suggestions on what to check? It's connected correctly, thanks.

Edit: Oh yeah I have a 1990 Celica GT4 but I don't think it really makes a difference.

did you ever screw it right down? Maybe the ball is stuck in its seat.

Yeah I did at one point because a "mechanic" thought it was a bleed valve, but I've popped the ball out of the bottom before I took the play out of the spring and put it back in. I still can't get it to run low boost. :D

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
