So I'm currently half way through replacing a few parts on my S2 R33 Skyline, just wondering if I'm going about it all the right way/any suggestions.



This is whats already happened.



HKS Air filter.


Blitz FMIC


3" Turbo back exhaust


Full Tein coilovers


Electronic boost controller



This is whats going on at the moment.



Apexi power FC yet to be installed/tuned.


Hypergear Hiflowed RB25det turbo.


Z32 AFM.


555 Nismo sidefeed injectors.



Would I have any use in upgrading my fuel pump at this stage or will the stocko be capable?


Any insight into how much of a power increase I can expect to see if my tuner knows his stuff?


Anything else I should be considering?



Thanks, Jess.

The limit is clearly going to be whichever is the lesser of the capacity of the 555cc injectors (which is less than 600 engine HP) or the capacity of the turbo. Depends on which highflow it is, but probably more like <550 engine HP on that.

And hell yes. Do the fuel pump.

I agree with getting a new pump and coils. What milage is on the motor???? I once did almost the same thing but i went with HKS 3071proS turbo kit. It was still side (low) mount and ran great. Thats where the new clutch came in handy as well. I wouldn't do another HKS turbo again due to price. But a gt30 is wonderful at that setup. Providing the engine is in good health. Good luck intrested to see how it goes:D

Yeah the hypergear highflow service has great reviews and I wont have to change any piping which won me over. Quite healthy motor roughly 140k, 160psi across all cylinders and no coolant or oil usage. Not sure what coil packs are actually in at the moment I don't think they are factory I'll post some pictures tomorrow. Thank you everyone for the feedback!

    • 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.
