I know its hard to hear as a newbie to search, you just want to hear the answers. But the answer is it depends on so many different things about what you want out of the car, which you havent specified. The best way to understand this is to read through the different topics on this forum and get a good overall understanding. If I was going to drop $20k to modify a car I would be researching the crap out of it.

Important things which I was not aware of before owning a rwd skyline:

- Lag, being a small 2.5L engine if you go for any more than 250rwkw on 98 fuel then you will notice an increase in lag. This continues to increase as you go higher in power. Over 300rwkw and you wont be seeing full boost to after 4000rpm at best. That only leaves you with less than 3000rpm of useable power assuming the standard rev limiter. But since you are talking about building the engine you could potentially raise the rev limiter with the right engine mods and this could be ok

- Traction with a rwd, even the standard turbo with a few mods and tune can be hard to launch in 1st gear without heavily breaking traction (with standard type tyres). I have 280rwkw and it can break traction in second gear even with wide grippy tyres.

- Axle tramp, I experienced a fair bit of axle tramp (wheels bouncing up and down as you break and regain traction), to resolve this you need to address the suspension which can be tricky to work out what is causing it. Super stiff coilovers can make this worse.

- Fast, the other thing is how fast a skyline can be without huge power figures. They are a lighter car and dont need the huge power figures of an XR6 Turbo to be fast. My car with 280rwkw is very quick, I would expect to run high 11 second 1/4s with a good launch and is plenty for the street.

Have a good think about it all and do plenty of research. If your talking about dropping a tonne of cash then I would look at a GTR, that way it should hold its value better and you have some hope of getting big power to the ground.

Best of luck!

It's a spring loaded momentary switch. Press it once, that should turn TCS off (and light in the dash), press it again TCS on (light off).

Are you sure TCS is operating? (Can check this pretty easy comparison with TCS fuse removed) Have you checked to see if the TCS switch is plugged in? (People often unplug it when doing work under the dash) Does the TCS bulb in the dash light up when you turn the ignition on (but don't start)?

checked the switch its plugged in, the light comes on when the ignition is turned on but pressing the switch has no effect traction control is always on :-(

so does taking the tcs fuse out disable traction control?

What makes you think that traction control isn't being disabled? Can you drop the clutch in first and smoke it up?

But yeah just pull the fuse, it stops the module getting power.

yer like i said wouldn't spin no matter what the switch did, pulled the TCS fuse now we can have some fun feels more responsive too

he's taking it up to mercury motorsport in a couple months for turbo fuel pump injectors ecu fmic exhaust and all the other mods to get it to around the 250rwkw mark

      R32 update from 1990's spec.

      New CAS just turned up from NZ Wiring. Looks like a nice bit of gear.  So, yeah. Triggered, bro. Realised I may as well do the cam belt while mucking about with it so will order one of them.

      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

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

      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.
