Hi all,

I have a S2 R33 GTS-T manual. Its done 89,000ks and and so far I have done the following:

- Full service (inc. plat plugs, timing belt, engine/box/diff oil, fuel filter etc etc)

- Put the std airbox back in with a BMC filter and a custom made scoop to direct air into the snorkle

- 3 Inch bell mouth style dump/front pipe

- Car already had an Xforce cat and a stainless 3 inch jap system (its too quiet though, i think the rear muffler might be a bit restrictive, its huge!)

- R34 SMIC with all the ducting (i used this cooler to keep up the responsiveness as im after 0-100 mroe than 1/4mile)

Now next I want to flush and bleed the clutch and brakes and change the wheels from stock, I want something with wider tyres as well

Now my bench mark car is my mates BF XR6 Turbo Series 2 (typhoon engine basically) with the 6 speed auto. The thing is a bullet.

i am not looking to build a quarter mile car, the thing is a daily and I want it all legal but I would like to be able to bust his XR6T.

What would you recommend I do next without spending huge dollars? the car runs really well atm and is really economical so I dont want to upset that either.

I was thinking boost controller? or doing the earthing mod to get 7psi all the time? what do people recommend? will this upset the tune and send it into R&R from where I am?

any thoughts would be great

First of all can you launch hard now? If you cant launch now then more power is only going to make your launch worse.

If you cant launch:

Then start launching, if you cant get traction as R31Nismoid said get some better tyres and look at suspension stuff.

If you can launch but need more power:

Find out what boost you are running. I was running 8-9psi with a full exhaust and no boost controller. Make sure you get to 9-10psi.

Then get a tune. That will get you 180-190rwkw.

Before doing anything engine wise id recommend doing a fuel pump, you never really know the condition of the standard, running lean never good. Up to you tho, you have low k's. Up the boost to 10 - 12psi, however factory 33 ecu's have a point when too much boost triggers the last timing column in the ecu and pulls back timing something cronic so be sure you stay under that. You'll feel it. Use a decent boost controller , ball n spring types are normally decent enough. Could always chuck it on a dyno with a knock block and a/f's n adjust ya crank angle sensor timing till just before you get detonation, thatll give ya some more.

yeah wheels and tyres are my next mod. I can launch the thing but it struggles with traction if I take off any harder than using about 2500rpm. So that is definately next.

It running std boost at the moment. I was thinking of doing the earth mod to get 7-8 all the way through but will this upset the computer tune? i dont want it to run badly.

Longer term I want to so something with the turbo and a proper tune but I have spent too much on it recently so I have to pace myself :/

You definitely need more traction then! Need better tyres.

Find out what boost you are running now. With a full exhaust even standard boost is higher.

FMIC! r34 smic is shit especially if your going to be upping the boost. Get the boost set at 12psi, NGk coppers at 0.8mm, tune and tyres. Stock suspension is good for launches :/

Still wont beat a xr6T though.

to be around mid to high 4 seconds mark youll need

clutch

intake

exhaust

tune

fmic

tyres

suspension work

good launch control

with those mods i had 192rwkw and was able to get 4.8 0 to 100km/h which is pretty quick

the whole 0 to 100 comes down to launch, if you cant launch, dont even bother

so much time is lost in recovering a botched launch

if you dont know how to launch, less RPM is better than more, ie 1200rpm launch is ideal if you have no idea vs 2500rpm

its all about clutch controll and getting it on as quick as possible

top out 2nd, dont bother changing into 3rd

Has anyone tried launching in 2nd?

I tried launching my car in second the other night - 5k fairly quick clutch gave me a second of wheelspin then it BOGGED down bigtime - never gonna work with a 3076 i don't think...

Stock XR6T runs what 5.1 sec 0-100 time. Why cant a well launched skyline with 190rwkw match that?

it would, if not better it. But its from 100 to whatever that a xr6t would munch a stock turbo skyline :miner: thats what i meant.

theres your problem. no clutch slippage. you cant just expect it to grip and go without wheel spin or bogging. abuse that thing like a red headed step child. :miner:

It's hard with a brand new extreme HD clutch...! Such a small grip point it's almost on or off til it wears a bit...

No arguments there. But us skyline drivers are more sensible drivers arent we so dont need to worry about that... :miner:

      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.
