Your spot on mate, only thing "maybe" cams if your budget allows, if it does not, dont worry as they are not essential.

Everything you've listed on the "to be done list" is exactly what i would say... Just make sure the fuel pump is getting the right voltage and you should have a good setup

i currently have 228rwkw also chasing 250rwkw

i have

power fc

hiflow plain bearing turbo

walbro fuel pump

ces split front/dump pipe

FMIC

AVCR ( Set on 12 psi )

Hiflow cat

3"exhaust

I am soon to have installed a Z32 AFM , nismo fuel reg, and 555cc injectors, and goin to bump it up to 18psi

We are led to believe, might be able to crack 260rwkw safely

And as for lag, mine has hardly any at all, even though its plain bearing and does produce more heat, and more time to spool, Too small of a turbo to notice .

Im in the same situation as for not wanting to open up the engine, as this will be my last of mods, b4 i would have to look at doing this, if i want my engine to last.

how much power is it safe 2 make with an rb25 and how long will it last for being a daily driver.. happy 2 peg it at more like 200kw fro daily drives but want more when teaching ricers leasons

250rwkw is pretty much the limit ( as i have heard) on a stock engine

making sure you do oil changes, and keep up maintenance.

200 rwkw is pretty safe to drive around on, aslong ya not flogging the crap out of it every second,

I have been on 228rwkw, every now and then give it ago, for about 5 months or so, havin the injectors and afm on its limit.

I really should get the 555cc injectors in and afm changed, but still saving, and spending money on piss and fuel.

And i ran 230rwkw and mine died... who gets what is really irrelevant.

Hell i've seen a stock RB26 bottom end thrash out over 500rwkw.

It died in the end, as with everything

Anyway, 250rwkw is a good target and a good limit.

Much more than that on the street is pretty much pointless anyway without spending mega $$$ on tyres and suspension etc etc.

Ive seen just under 400rwhp last (and still going) on a standard rb25 for quiet sometime! If the tune is right and you treat it properly your target is no problems for the motor, wether or not your turbo will do it you'll have to find out!

As mentioned regular oil changes keep your motor happy hehe

    • 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.
