hey,

everything is pretty much sorted. cooler piping, tailshaft, gearbox mount, bonnet shutting, rad, etc.

But am just a little unsure on a couple of pretty simple things.

1. have had the plenum refaced, with the throttle body at the front now. However throttle cable doesn't reach. Can it be extended, or do i have to get say a bigger Vl, r32, r33, or other cable.

2. Am not running a bov, so can i just get the rubber hoses which go the bov blocked off at the plenum. The black metal piping which leads to the bov on the turbo side have been taken care of.

3. With the new cooler piping there no place to plug in the vacume line for the wastegate. Can i just extend the line and get the reading off any part of the plenum, or is getting it off the cooler piping on the turbo side essential.

4. for the boost gauge reading, does that just get it off the plenum also.

5. for the vacume lines which go to the throttle body, now that at its at the front, is just getting a bigger line ok, will it effect the throttle body opening, and operating the way it should.

6. whats the best way to drain the fuel tank?

any help much appreciated. i will post some pics as soon as i can get a hold of a digi camera.

thanks again

also run into another problem.

power steering setup. The silvia has some some speed sensative unit. and theres 4 lines coming off that, yet theres only 2 spots on the rack.

And putting in new lines mite not be viable cost wise at this stage.

Just wonderding whether i could take out the power steering lines, pump, put fluid in the power steering rack, so it doesn't run dry, and block off the outlets and inlets, so no fluid can go in or out.

only worry would be whether the rack will suffer, or turning will be come impossible.

Anyone know what the go is.

Is it safe to do? or should i run new lines, but then if i bypass the speed sensative unit, it could cause problems up at high speeds, pretty tight for room with this one. and i got lines going everywhere.

thoughts on this please.

oh and i got the tank drained, hooked up old fuel pump ran it off a battery and pumped the old fuel out through some hose. worked well.

GTiR throttle cable fits on R33 with front facing plenum. I have been told you can get the stock cable modified as well.

Two spots on the steering rack? why not use an R33 steering pump? I think the R32 have like a dual pump with two lines for the rear hicas, and two for the front steering. If your pump has 4 outlets, do 2 of them run from a seperate resevoir? Sorry I dont have much of an idea what is exactly wrong with the power steer - but interested to hear what the problem/solution and outcome are?

Cheers

      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.

      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.
