Robs Sil80-more skyline than S chassis, 180sx Race Car and bogan chariot

Recommended Posts

Haha we have very similar tastes. I have an RB20 S15 street car and just picked up a basic SR20 drift car same as yours.

I bought a G4+ plugin for it and adding Oil pressure/temp, Coolant pressure/temp, Fuel pressure/temp, Manifold air pressure/temp and flex fuel sensor. Can throw up some pics of how i did it all if you want, was a bit of dicking around but well worth it imo.

How did you get the s15 rego'd with a rb20?

Wiring is easy stuff for me and the Link is very user friendly. Planning to pull the full engine loom and do it properly, won't be as good as the sil80 loom as I made that from scratch.

Spent a bit  of time today going over the car.
-checked plugs 👍
-compression tested 👍
-checked for blocked intercooler 👍
-dropped cat and all clear 👍
-rechecked base timing 👍
-checked catch can, empty
-re calibrated throttle pedal & throttle body. This may have been an issue as car now rev's more consistant and goes to limiter.
- Ordered new 14psi gate spring

Hoping to get back on the dyno late next week to have another go at sorting the 98 tune.

Now I have 24hrs to prep the new 180sx for scrutineering friday night & racing on the weekend

And then?

Short of it is stripped sil80 of all its suspension, brakes, diff and steering into track car, raced it, took out a chicane tire barrier, fixed it and now sorting it out lots of small things to make it reliable for the rest of the year before drift event next week. 

Will do a big post tonight

Okay time to grab a beer and update on whats happening with the fleet of S chassis'

As I posted about 2 weeks ago I bought another 180sx. Was right price, a few good bits and local.
Plan was to just look over it fresh fluids & race it........ 24hrs later I made the call to strip my sil80 of all its go fast handling bits- MCA coilovers, rebushed rear cradle, gtr diff & axels, Steering rack, rods knuckles & Brembo brake setup. 14 hours later it was all swapped then had to do all fluids, flush cooling system and sort out a new steering wheel as the Ebay special on it was F*!cked. Raided my cupboard of hoarded goodies and fitted up a Keys racing wheel.
Wheel alignment on the friday and it steered a lot better but steering was knotchy/not smooth.

Saturday morning of race day came & still was trying to finish off little bits. 
First laps in the rain, cold tires and a bit too much right foot had a few spins. Started to get more confidence as track dried out and pushing my braking point a bit too far, took out the chicane tire barrier with a massive front right lock up and understeer. I was lucky as a mate was filming and got it all. Result was a bruised ego , bent front guard, head light and more cracks in the front bar but worst of it was flat spotting my RS3 fronts.
Pulled/kicked the guard straighter put the lights down and got back out there to get 4th in class and 9th outright which was a good effort.

So after that weekend found a few things I wanted to fix like the shifter as I would always grab 5th not 3rd on up shift from second, catch can setup and the steering rack.


Ordered a heap of stuff from Taarks and got about fixing it all but as I pulled one part off found heaps  of stuff I wasn't happy with.
Ended up stripping & cleaning cooling system- new rad hoses, thermostat, clean radiator, clamps. I would say the system had not been looked after as brown muck was coming out for a while. All sorted after a treatment and now using penrite coolant.
Replaced all the vac hoses and removed the "2 stage" boost controller and added a mac valve to control boost through the ecu
Replaced shifter cup, ball, springs and rubber boots
Moved the battery behind the seat after finding only 2 m6 bolts drilled through inner guard securing the battery. New isolator switch and proper earth cable.
Added a Cobra Suzuka fixed back my mate donated from our targa car as it was flooded and written off during the floods last month.
Installed my old defi setup as the SuPERCheap guages didn't work properly
Went to rebuild the steering rack as it was leaking on one side and found it was bent so grabbed a spare & rebuilt it but i stuffed up as it leaked too. Grabbed another rack and having a local shop rebuild it. Hopefully get it back tuesday.
Ordered a half cage from AGI as new cams passenger rules require one.
Started the car up after replacing the IACV hose and had stupid high idle. After pulling the solenoid apart it was missing a sping & gunked up so cleaned it and inspected the old hose to find a restrictor in it. A local shops handy work.
Fitted a vented fibreglass and bought some widebody front guards as these are full of bog and some rust came with a pair of side skirts too.

I'll pick up where I left off.
Got pretty much everything sorted but didn't get on the dyno so just sent it as the kids say.

Lost the starter motor before the day started then got 2 runs and lost power steering. High pressure hose let go so just ended up being an official for the weekend. Great event and now getting ready for the next one in 2 weeks.
A video from one of the local media guys

As usual I was going to fix the 2 things that were broken but that escalated very quickly 
IMG_20190401_201535.thumb.jpg.e28a1bb83434a01ad4f5e7c038b06cc1.jpg


Pulled the whole driveline for a quick inspection and found a lot of small things that needed fixing- Leaking rear main seal, half worn clutch with wrong cover plate bolts, perished hoses, cracked exhaust manifold, leaking exhaust, gearbox rear seal, loose balancer bolt and the list it goes on.

After emptying my wallet and funding Taarks retirement I replaced all gaskets, resealed sump, put on standard inlet & exhaust manifolds, New NPC RB clutch conversion, all hoses, Taarks fuel rail, Taarks power steering relocation, gearbox mount and a quick respray rebuild ;)

IMG_20190406_170707.thumb.jpg.9a6dd9763bdc72eec449ceeb2767be04.jpg

Also decided on doing in bay cooler setup using current radiator with a r33 shroud and going a smaller intercooler, New Garrett GTX Gen2 2867 internal gate, new exhaust system (old ones baffles were loose and missing in parts), Injector upgrade to ID1650 and walbro 460L.

Got engine & box back in yesterday and spent this morning doing small things like hoses and p clamping the loom out of the way. 
Plan is to run 16psi, E85 and see how long it lasts.

 

And yes sil80 is still getting some attention. I have been ordering small clips and rubbers with every order from EFI Solutions and its new wheels turned up after waiting 4 months

Plan is to keep hoarding parts for the next few months and get back into it at the end of the year once all the racing is done.

Well fk that escalated quickly haha, also better to run a bit more boost on those GTX2867R, they love boost.

3 SRs I've tuned all have made 270kW+ on IWG with either stock or after market T2 manifolds with at least 25psi (all 3x SRs still stock motors too lol).

yeah, may as well while do it all while apart and do it right.
Shit thats impressive power, I am only after 220-230kw for now and heaps more response. I am on the hunt for another cheap stock sr just in case I do turn it up.

Just head studs, E85, good hotside, not too much timing in the mid range and they'll last!

Even with a stock HG!

Been a bit quiet with car stuff as been busy with running events the past weekend but managed to fit up the turbo with wastegate & dump pipe, all new braided lines. went to tighten up 2nd last nut and stripped the thread in the head so rage quit for a few days.
Welded cast aluminium for the first time and no leaks so happy with that. Injectors & turbo arrived too

New body kit arrived and started test fitting this afternoon also got the new bottom rad mount welded up and wideband bung. Tomorrow's plan is to finish rad & intercooler mounts and fix the stripped thread as I will have to take the whole manifold off.
Plan to start cooler pipes Friday as will be busy with ANZAC day activities Thursday.

Might get it running by Saturday hopefully before  leaving for Japan. 

also some good news with the DriveIT project with more funding announcements during this election campaign

got back from Japan this week. Was a great trip, drove some sweet cars & roads with Fun2Drive in Hakone. Drove a F355 & R35 the first time and then went back and drove EVO 6.5 to Fuji Speedway. Got to see two new supra's, Porsche 918, LFA, Ferrari 488 and Mclaren on the main circuit.

Have been slowly sorting the 180sx with the rollcage arriving this week. All fitted up but had to move my battery and modify the bracket a bit. Fitted up the shroud to radiator properly by welding a few tabs on and its in with a mix of hoses. Fitted up the front half of the body kit and happy with the fitment. Just waiting to get fuel tank & cooler pipe back from welder as I kept blowing hole in them. Plan to dyno Wednesday night and race next sunday before painting it and getting ready for Mt Morgan in July.

Solid update.

How do you rate the cars you drove? 

F355
sounds awesome, drove really well. It is very wide, was hanging over the center line on a few of the roads. Not for daily driving as the pedals are more to the center due to the tub design. Once its over 4000rpm it was a rocket. If I could find one at 2008/2009 prices I would buy one.

R35
comfy, point and shoot car but interior is boring. This one needs a gearbox service & wheel alignment badly. Gave me a lot of confidence to have a go in the wet.

EVO 6.5
Fun. This car surprised me very direct steering, quick through the twisty stuff and comfy. Shame they are expensive for what they are. Have had a serious think about buying one as the wife needs a new daily.

Still working on the 180sx as have entered the Mt Morgan Hill climb. 
Its all running and idle all sorted, going to dyno friday and will be doing most of the tuning myself for the first time so will be a steep learning curve. Ended up getting a new fuel reg as the linglong ebay wouldn't hold consistant pressure.
Body kit is all fitted up and not a tek screw in sight. All nutserted with  m6 bolts, spent way too much time making it fit nice so am having it painted properly on the outside for now in Mitsubishi electric blue. 
Tomorrows jobs are to finish fibreglassing the bonnet vent, weld on BOV and bend up some ducting.
Had a little bit of interest in the cars but nothing has come of it.

A few pics of progress

Got the car tuned during the week as tuner had issues with another car so couldn't get this done on original date.
Decided to paint it myself as missing the original date stuffed all our plans so pulled entry from Mt Morgan :57_cry:

Made 229.6 on wastegate pressure of 16.5psi 
669446754_firstdynotune26june2019.thumb.jpg.d60f282ac2ce5200ea9c8b90b911b449.jpg

Once I have done an event I will go back and turn it up. Car never went over 83 degrees and IAT of 25.8 at its highest after multiple runs. Pretty happy with it as there were no issues. The ducting & foam around intercooler definitely help.
Started stripping and getting it ready for paint. the rear quarters are full of bog from previous damage.
Setup my ghetto booth in the shed and sprayed it in undercoat after a big effort today. Got a few other cars to wire sensors & set up ecu's so hopefully will finish undercoating doors & body kit wednesday or thursday and start wet sanding friday.
