Hi all,

i have just installed a Blitz DSBC (Silver casing and blue back lit screen). Got it put on the duyno and have found out my fuel pump has had it....

Was driving home today and put my foot down a little and it seemed to do the misfire thing (as this is an Bosch fuel pump that just kacked it) (not sure whether its not flowing enough orhas shat itself) anyway it seemed to do that boxer engine type noise but along with a bit of a "chirpy" type noise as if it wsa coming from the turbo.....Decided to limp it home safely....

Im wondering whether it has been set up with too much boost and its just leaning out with this pump. That sed is someone able to tell me how to setup my boost controller so it runs as little boost as possible..possibly supplying a phone number?

Or do you think it may be that from the addition of this controller then boost is coming on stronger than before i.e. more earlier causing a misfire earlier or....????

Any help is greatly appreciated.

Cheers David

I tried moving it to off mode...did that... this but it would still register boost and if i put my foot down it would boost to like 1.3 bar

which is not to health for my stock turbo

and now im scared if i do try it again it will blow the turbo!!! help!!

Then it's probably been installed wrong. What boost did the car make prior to installation of the dsbc? Check the little switch on the back of the unit is set to "ac" and not "wg". The stock 32 actuator should make a maximum of maybe 12psi before dropping back to 10.

Made like 11 psi with tapering back to 9 or so in the higher rpm....however as the fuel pump was f**ked she was running a litle lean....(12.9)......but that was without the boost controller installed when she went on hte dyno......ill check that....but not sure i kno what i am doing....instead of trying to stuff around with it to much...shud i just leave it and just baby it until i get it all tuned and a ne wfuel pump done??

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out

      I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.

      I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
