Any suggestion on new injectors? Looking at the Bosch 1000cc injectors. I don’t want to worry down the line about replacing again if I do extensive HP hainsgains

Nice car - and welcome to SAU!

Looks like the steering wheel is still on the "wrong" side for you guys - are you allowed to drive them like that where you live?

I don't think you would ever need 1000cc injectors on an RB20, unless you fit a big laggy turbo and run on E85 fuel?

The new injectors these days can manage a wide HP range much better (ie a big injector can manage fuel OK for low HP) - but what sort of HP gains are you chasing in your RB20?

Checkout the RB20 turbo upgrade thread for info on getting results from the RB20

https://www.sau.com.au/forums/topic/103095-rb20-turbo-upgrade-all-dyno-results/

I have an R33, so I've never looked at the thread.

I'll likely get flamed by the R32 GTST crowd for this comment, but many owners in Australia with an RB20 in the engine bay look to other engines if they're seeking big HP gains (eg RB25, RB26, RB30, 1JZ, 2JZ, Barra etc).

I'm sure with the right mods you can get your RB20 singing, with ample power for a street car - I just don't think 1000cc injectors is the best 1st step.

cheers

Your car looks mint.

Don't do to much unless you plan on getting another one that nice.

once you start modding it's hard to stop ahaha.

1000cc way to big.

Fuel pump and it's wiring and lines first then injectors. 400 hp is about topping a 20det so you only need the injectors to be as big as gtr stickies 444cc.

Front mount intercooler. (Return flow to avoid chassis holes)

High flow rb25 turbo

Zorst setup

Pod filter.

Bleed valve

Aftermarket ecu

 

That should be enough for fun

 

Start with a bleed valve and don't boost over 12 psi or you will break the zorst wheel

      Duncan's V37.......race car?

      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.

      R32 GTS (RB20DE) Injectors Replacement

      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.
