for those plugs, you should leave them at 1.2mm unless you are getting a miss at high boost. The bigger the gap the better the burn, people only gap them down when the spark is not strong enough at high boost.

good idea to check stuff out early....can't say I've ever tried that :wacko:

So, my EOI entry for WTAC has been accepted smiley.gif guess they need some back markers to liven things up haha

Have some work to do in the next few months to bring it up to standard.
Can anybody tell me what the lowest weight "manufacturer's original specifications" for a HR31 is? Im allowed to have upto 15% less than that.

Got started on the weekend. As im going to be very under powered in open, my goals are;
-make better use of what the car already has
-make the car as reliable as I can
-have as much fun as I can. smiley.gif

Plans so far…

I don’t really want to pump any motor power through the motor as isn’t a built motor and I don’t have the cash to build one between now and then, So ive ordered a few bits and pieces like 25% under driven balancer and lightweight flywheel with arp bolts to free up some power. will aslo be getting retuned as well

I have a 9l gated sump to go in, heat shields, new wastegate diaphragm and lines, new turbo beanie as the last one is falling apart.
Spare exhaust manifold (old has cracked again) Im redoing the exhaust (this time side dump and screamer) to clear up the back end for the diffuser and save a bit more weight.

getting ready to pull the motor. also sort of how the exhaust will sit, basically just flipping it over cutting the end off and adding a bend to go out the side.

The splitter and side skirts are going to be dropped down to around the 70mm height rule, just with sheet alloy. Wont look pretty but should help.

The hydro is going too, as It makes bleeding a bitch.

Front guards have been spaced out 30mm help stop wheel well turbulence, don’t know if it’ll work but looks cool tongue.gif and i'll be making some bracing for the engine bay/firewall here too.
Was pleased to see little/no rust

And Ive bought a spare set of axles of Tir31 biggthumpup.gif just in case.

Got a little done on the weekend.

Putt the fittings put on to the new sump and fitted the ignition cut off cable. I’ll get some pics later..

Bit of weight reduction…. Im tiding up the bay while the motors out, bit of paint, fixing up some wiring and general messiness.

Cut out the radiator support panel for ease of removing the motor, knocked up a new one and some air guides for it too.

Not finished yet but you get the idea. Need to do something for the top of it too.

Old vs new flywheel

2013-06-30150437_zps12e51ea5.jpg

Well, im feeling quite loved atm :) Fatz the top bloke he is has started a thread to help me get to WTAC. And so far has raised a heap of the folding stuff, help and even a sponsorship deal with Australian & Japanese Dismantlers for a set of tyres.

This has really taken huge burden off me and I am really grateful for the generosity shown by the members of this club, Thanks heaps everyone! :)

Engine bay degreased and a lick of paint to make it feel pretty. New cam cover gaskets have rocked up today, so tonight I’ll prep and paint the 25 cam covers.. the extra volume should help keep a bit less oil making it to the catch can.

I put on the modified sump (think its about 8l with gates) and new balancer (which is tiny). Also a new timing belt and tensioner while I had easy access.

2013-07-07150216_zpsaee5401a.jpg

Just waiting on one more fitting for the new head drain hose, then I’ll slap on the flywheel and put it back in the car.

Ok, I have a little question.

My current exhaust manifold has cracked (again) and I don’t really want to re-weld it.

I have two options, either buy another and keep the same setup or use a Twin Scroll manifold (has two old HKS wastegates) that I already have but will need to buy a new turbo housing for.

It should be about the same cost, just a little more work to go T/S

The turbo is T3 atm and the T/S mani is T4

What are peoples opinions?

I would put a steam pipe single scroll mani on it. Your putting in a lot of effort to make the event, would be a shame to have a thin wall ss manifold crack or old waste gate fail on the day. TS would be nice but it comes at a cost.

I have decided that the money from the donations will all go towards tyres. I'll do a sexy poise on them when i get them :)
This has freed up enough money that i was able to replace the manifold rather than weld up the cracks again.

Its a one of the Mild steel jobies from Hybrid in NZ, the quality is actually pretty good (better than the chinese one) I didnt get a pic but its all smooth in the collector and the face of the flanges (thick too) a straight. It puts the gate futher away too, which i think will help with the diaphragm issue.
Also rerouted the water return, put the new beanie on and have use silcon hose for the wastegate.

New oil drain from the head to sump

2013-07-16180701_zpsa043dbb9.jpg







I have also finish painting the new cam covers. dont you judge me...




YELLOW!!!

I think it'll look good in an all black engine bay. Ive painted the strutbrace and boosted stopper i made black so they dont stand out too much.

I'll put the flywheel and clutch on and hopefully have it back in the engine bay this weekend.

What do people think of Royal Purpal oils? thinking of trying them as im a sucker for advertising

What do people think of Royal Purple oils? thinking of trying them as im a sucker for advertising

I've used all the top oils, even the $50/l stuff and they all effectively work the same....basically none of them provide significantly better protection and performance than each other.

Obviously use synthetic, change it often, and make sure it doesn't get too hot. But don't worry too much about which brand

ok, no worries. cheers man

thanks guys, the CAS isn't polished. its a modified one thats been ceramic coated inside and out. i was given it a while ago, but haven't been sure how to setup the Vipec for it (has 32 hole wheel). ESP's job :)

been meaning to get back out there for awhile now. but, yeah after s/l

will be interesting to see time difference, it was my first trackday with the 30 (220kw) and reallllllyyyyy old 225 wide 595RS's.

got a bit more done on the weekend

Motor back in
2013-07-21171136_zps06299464.jpg




guards are back on too, and have been spaced out.

not sure how much benefit there will be for a box shaped car but it didnt cost anything and hopefully will help.

    • 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.
