hey all how yas going, tony here

today i got my blitz dsbc installed by PROTEK AUTOMOTIVE in preston, i have the r32 gtr 1989 model with the stock turbos in it,

the modifications to the car are:

apexi power fc

greddy adjustable cam gears+greddy timing belt

hks dumpipes

custom front pipe

custom 3" cat back, all stainless from turbo

straight pipes all the way through from turbos

blitz dual solenoid boost controller

the car on the dyno was comfortable at 14psi so the car is currently on 14psi,

its not a daily driver, its more of a weekend driving vehicle and racing the 1/4 mile every 2nd week or so

today my car produced 237kw at the 4 wheels on 14psi, what yous wrecken for the mods that have been done to it guys

It should be safe, depending on the condition of your turbos. No one can say when its going to break, its mechanical, but common sence says 14psi is safe for stock turbos. My mate has an R33 GTR, stock turbos, just fitted apexi pod filters, cam gears and power FC, is also running apexi AVCr boost controler. Now he runs 21psi through stock turbos, has been for the last 6-7 years that he has owned the car. I took the car down to CRD for him to have the cam gears fitted and tuned, Jim almost fell out of the car when he saw what boost he was running, with stock turbos, I said, "Well thats what he always runs." which is true, car made 260awkw at 21psi. Jim turned it down to a safer 19psi and the car made 250awkw, now this is still well above what recomended and regarded as safe for stock turbos, but like I said he has been running this ammount of boost since he bought the car about 6-7 years ago and the car still runs perfect. Car is an R33 V spec. Its quick, people say it will break, but it hasnt yet and he flogs the shit out of it. So its like I said, its mechanical you just dont know when it will break, you just have to be prepared to fix it when it does, but the amswer to your question is: You are running the highest recomended boost level for your turbos.

The power level sounds about right.

While its 'normally' ok, running 14psi through stock turbos on an 89 model GTR is asking for trouble.

Blitz, why is it not ok to run 14psi on an 89 model as aposed to other models???

i picked up my car today and my mechanic said my blitz dsbc is not that good, he said they are normally a good boost controller but my one isnt the best he says, on my dyno sheet the boost level is not dead straight, its spiking on the dyno from 15 to 16psi, what should i do, he said get a new boost controller(just the unit itself) so please guys does anyone know where i can get just the unit from, i also want the newer stlye blitz dsbc, i already got the solenoids so dont need them but just ned the unit asap please guys,

cheers people and thanking everyone for the help

Dont know if you can get htem sepertly, might have to buy the whole unit again unless you find someone who is selling a second hand part. I just bought a Blitz i-colour dsbc new from Japan $650 posted, my sister is over there at the moment, I thought I was getting a bargin till my phone bill arrived!!! at over $150 in calls to Japan!!! Anyway SUch is life, i guess. Good luck. I would first check that it is connected properly 1st and if it is and there is a still a problem then you should probably just buy a new one. Just take it easy till it is all sorted. Goodluck

you took it to a shit tuner man. i took my car there and dom told me 13 psi is safe as a house on my car. 2 weeks later the stock turbo blew.

and he told me my stock fuel was maxing out at 173rwk. what a joke.

i took my car with the same fuel pump to get dyno'd 6 months ago at creatd motorsport and i got 209rwk.

creatd ftw :nyaanyaa:

and my af ratio was 9:1 when protek done the tune. thats why the fuel pump was "maxing out"

13 wasnt safe for me especially after doing some research. i got a series 2 liner= crap turbo

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
