hey guys just recently got my hands on a r33 gtst, im new to the whole turbo scene and wanna sort some stuff out to be sure im not doing damage to my car in the mean time,

firstly, my car has a electronic boost controller which has 2 settings, lo and hi. the boost controller reads in a %, does this mean its calculated from a % of the stock boost? and if so what is the stock boost a r33 gtst, ive heard its 8 psi. when saying this i mean if i set my boost controller to 20% for my lo setting this would mean id be running, 8 psi + (20% of 8 = 1.6) so my total psi would be 9.6. Also wat would be a good safe lo and hi setting, lo for everyday use and hi for an occasional use, i was thinkin 8 for lo and 12 for hi?

also the car came with a after market air intake, Ive been told to remove it and replace it with a stock air box because they suck in to much hot air and increase work for my cooler but ive also been told thats not true and to leave it.

sorry for any stupid questions just wanna clear things up so many people telling me different things.

thanks

get a boost tap instead

downgrading is always the best way is it?

you can set it yourself if you can watch boost while driving (depends where your controller/gauge is) but if not get a passenger to help.

as for setting the boost you want, have a read of this

basically increase the percentage til you reach the boost you want then play around with the gain and set gain to bring it on boost harder/softer. if it spikes back off the gain

Your best bet is to use google and find a manual for your boost controller which should explain what everything does, if you cant find one (or there all in jap) search this and other forums, will be a tutorial some where explaining what everything does.

also the car came with a after market air intake, Ive been told to remove it and replace it with a stock air box because they suck in to much hot air and increase work for my cooler but ive also been told thats not true and to leave it.

If you have a pod that is not shielded from the under bonnet heat then you will just be sucking in the hot air from under the bonnet, airbox's have been proven over and over again to be able to flow enough for 250rwkw (some claim even more) with a good panel filter, if your in vic you will get defected for having a pod and a front mount so your best off going back to an airbox.

Also in vic that hard pipe its self is another defect, you can only have 1 intake mod, if you have a pod, intake pipe and front mount intercooler then you have 2 defects there already, there is a thread in the tutorial section showing you how to make it so the rubber intake pipe does not suck closed.

      Not too sure just yet, want to have a go at doing what I can myself, but to start with want someone to cast their eye over it tell me what needs doing to get it running and back on the road, so anyone with great overall knowledge would be ideal.

      Rear subframe stay bracket bolt removal issues

      By MBS206 · Posted

      I personally would go with cutting out the rubber. Then deal with getting sleeve off separately. Rubber can be painful to cut, it loves to jam up cutting tools. I normally have success with drill bits, deburr bits, angle grinders, jigsaw, reciprocating saw, and never forget... fire. Obviously different tools won't work in all locations you're trying to work with, and you need to be comfortable with each. You personally may be happy slowly slicing it out with a razor blade, if you are, go for it with one too! Feel free to wait for others to weigh in also on their thoughts.

      Rear subframe stay bracket bolt removal issues

      By DatsunBanana · Posted

      So ... I got everything disconnected and started dropping the frame. Three of the four mounts started to come down but the fourth one (the one with the nut that gave me all the trouble) won't budge. The inner metal sleeve stays up tight against the chassis rail although the outer part of the mount drops a bit (and can be levered quite a lot more) but it's just stretching the rubber bushing. So I reckon there's some serious corrosion inside the inner sleeve and holding it tight to the lug at the top of the bolt. Tried everything I can think of so far: penetrating oil, whacking the top of the sleeve to vibrate it and wedge a screwdriver blade in there. I also tried to turn the inner sleeve a bit by hitting it with a chisel at the bottom. It's stuck solid. What do you think about cutting the rubber with a blade so I can drop the subframe around it anyway. Then worry about getting the inner sleeve off after? Will that work? Is it gonna give me even more problems?

      Blue/grey smoke after idle

      By hypergear · Posted

      Steam valve seals are usually responsible for cold start smoke, it goes away once engine warmed up. Disconnect it let engine breathers and let it breath freely, see if problem goes away after a short drive. Also check to make sure engine oil drain pipe is not blocked or kinked.

      Haha thanks! Yea I'm moving over from 2x 1000cc jets pre throttle over to 6x 190cc direct port jets and 1x 500cc pre throttle jet.  Direct port comes with all the advantages you would expect, except that pre throttle does cool down IAT'S more. That's why my direct port nozzle placement is closest to the plenum as possible in the runners to allow the air more time to cool before being sucked in. I'm also putting that one 500cc pre throttle jet to help with more cooling. It's a hybrid system. There's a lot more advantages to moving over to a PWM solenoid with a constant pressure system vs my old PWM pump setup, but I'll get more into that once I'm done converting everything over. The ricer in me is excited to see SS tubing all over my manifold though!
