What does it matter? As if you're going to take what someone says on here is a "safe" boost level, adjust the boost up to that level and just drive away, believing that the injectors are not maxxed out and the mixtures are fine.

For a start, you do not fit any sort of "upgrade" turbo to an R33 RB25 without looking into the engine managemane problem. The problem? That the original engine management sucks balls. You simply must install some sort of aftermarket computer in order to be able to fix that. Otherwise you install your 2510 and then you make sure you do not boost it (assuming it has a decently high wastegate actuator installed on it). And you drive it around with a thumbtack in your right sock to remind you not to boost it.

If you wind the boost up to anything over about 10 psi (plus or minus the various uncertainty factors) the car will start misbehaving and go into R&R. And the injectors will be maxxed out because the mixture settings in the stock fuel tables are well over 100% duty cycle up in R&R territory. This won't matter, because it will drive like a piece of shit and you'll be on here asking why it's farting and spitting and blowing black smoke.

i do have an aftermarket ecu, i have a tuned greddy e- manage i am aware that the stock r33 ECU are very sensitive, if it only makes 10 to 15kw thats still better than the stock turbo and i wont have to worry about bout my stock turbo shitting itself, i did get that turbo for a cheap price.

Just sell it for a profit and buy something that better matches the rb25 then. http://www.skylinesaustralia.com/forums/topic/437073-hks-gt2835-kai-kit-for-ecr33/

Sell it and get a 2530 at least or a hypergear high flow, will make 230-240kw with stock response and save money as you'll just end up doing that eventually anyway, no point getting two tunes when you could just get one and get the power you want straight up

Johnny's right ^^^

Ive still got my 2535. There worthless nowadays. I can barely give it away. My b rother took my spare and the one on the r33 will probably sit in the shed when I upgrade the whole hot side.

SELL 2510 BUY HYPERGEAR = WIN

yeah, you guys sound right, im selling it, ill just get a highflow.

put it on eBay and use key words like BOLT ON, RB20DET, HKS etc.. someone (hopefully not from this forum) will buy it :)

then get your stocker high flowed by Hypergear and fry tyres

I've been in a 2510 powered R33, made a little bit more than stock but really wouldn't hold over 1bar-1.1bar to redline. Unless its cheap/free or already came on the car i wouldn't bother.

    • 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.
