Scratchy Orange Build Thread

[autoracer86]

Well it finally happened after many years living in Ireland I got myself a 2nd car for track usage and road trips around the EU(Mostly to race tracks hehe).

I got the car 7 months ago when prices here in Ireland were skyhigh. Most GT86s were at least 20k most closer to 25k. Anything 2017+ Was was 35 or more... One day a 2014 Orange 6 Speed pop up on the market for 16,500 It was a CAT N due to a front end collision when it was still new at the dealer.

With Cat N being non structural I figured what the heck and took the risk. The front end repair work is pretty bad and the paint just awful but hey its a track car so who cares

Home and first wash. Definitely a 10 footer

2 months later I was Prepping for my first track day with the GT86. I didn't do much to the car. OEM oil cooler kit from NED, Tossed on pilot sport 4 along with an alignment, And got CL Brakes RC6 compound all around along with 4 new OEM rotors.

For brake fluids I ran Castrol SRF Racing, Motul gear300 transmission, gear300LS in the Diff and Mobile 1 XE1 5W-30 in the engine.

As for prep I did beyond the car... Aim solo DL2, Smarty cam 3, Trackform headrest mount and a Bell helmet GT5 sport.

Some pictures of Murry Motorsports for the Americans who order their seats from him lol

The first track day at my local track Mondello park went off without issue. In truth I didn't get to do much driving as there was a lot of red flags in the morning followed by some slight rain for the afternoon. Plus I am a two driver car.

I managed to finish the day with a 2:22.69 2:20 as my best theoretical due to a lift on the straight. After speaking with a few local gt86 drivers it looks like I am way off the pace as in NA form they are running 2:05s with similar mods and tires. We have our benchmark now at least.

This was my first time using AIM equipment and it worked well. No missed laps or video. Everything started and stopped on its own. I was pretty familiar with race studio 3 as I used it with iracing and watching hours of videos from AIM so no issues there.

So where is the video I here you ask.... lol Well beside the fact my GF is saying all kinds of silly nonsense the damn camera moved during my best lap and blew out the auto exposure haha.

I already have another track day booked for this Monday and I will make sure to get some good footage

Lol, somehow I never connected the dots that Murray Motorsports actually had a brick and mortar presence, that is awesome.

Happy to follow along here

I was telling my buddy in the states I was going there and he begins to tell me how a lot of racer use them haha. I found the whole thing really funny.

Thanks for following along. Will be posting some of my new mods pretty soon then some track day video assuming all goes well Monday

[autoracer86]

My first set of mods have been ordered and mostly installed .

• Whiteline rear diff insert kit
• SuperPro rear subframe bushing insert kit
• Beatrush Brake master cylinder brace
• TRD transmission mount
• TRD Motor mounts

Beatrush Brake master cylinder brace
For the price and ease of install even on the RHD cars it's worth it. I will say I mostly bought it because of how mushy/soft/dead the pedal feels for light around town inputs.

The brace did not really help with this but it did make a difference overall. The pedal requires a bit more force and just feels more solid when you really step on it. Overall I am happy

Whiteline rear diff insert kit
It feels crazy saying this but these inserts changed how I feel about the car. I was in love when testing these things out. Besides the car just feeling more solid it also feels faster which I assume is due to putting the power to the wheels better.

The car feels sporty and inspires confidence. I was and still am shocked how much more I just wanted to drive the car. NVH increase was zero. Overall I LOVE this mod and it was the reason I ended up ordering the TRD mounts. I just wanted more !

Oh and install is super easy

NOTE I only installed the rear inserts. I was told doing the front inserts would cause too much NVH.

TRD transmission mount
Installed this one this morning. Not too difficult even left the front pipe on. Shifting effort is a bit increased and the 3rd to 2nd shift feels less crappy. NVH increase was zero. I like the way the shifts feel over stock and happy I did the install.

Since my motor mounts are still stock one thing I noticed more is the motor moving around. I would not recommend just doing the transmission mount.

TRD Motor mounts
Not installed yet. I have an appointment with my local dealer to get this installed Tuesday. Let them deal with the rusty exhaust bolts. 260 for install if anyone was wondering

SuperPro rear subframe bushing insert kit
Planning on installing this before my Track day on the 21

[autoracer86]

10/4/23 Trackday at Mondello with trackdays.ie
I was much more prepared for this trackday than my last largely in part to many hours driving a Orange GT86 around Mondello in Assetto Corsa

My goal was 2.10 down from my best of 2.22 but between weather and traffic it was not meant to be. My best lap which was far from drama free and on a damp track was 2.18

Still managed to have fun and ended up with a few good "battles" Unlike last time were I wasn't keeping up with anyone on track

For my second time at Mondello and second time ever on track with the GT86 I was happy. The car didn't give me any trouble and oil temps were never above 235F. I also got some good data and video to review for my next track day on the 21 which is a limited event to only 30 cars total 15 on track at once !

My future plans are a trackday at silverstone in June then let the real modding begin. First up Suspension thinking RCE SS2 along with RLCA and toe links

[autoracer86]

TRD motor mount

Quick update picked up the car today and I am very happy with the improvement. The motor doesn't slap around like it used. Any movements from the motor are subtle instead of jarring.

With all the mounts installed the car feels more "upscale". The way the motor and transmission moved around in stock form was always off putting to me. Feels great now and just like the TRD transmission mount there was no added NVH


Only thing left to do now is the subframe inserts.

[autoracer86]

Just looking over the data figured I would jot down a few things to make it easier to track progress.

Track Temp 50.2F/10.1C

• Max Speed: 89MPH/143KMH
• Max RPM: 7378
• Max Brake Pressure: 701PSI
• Max Oil Temp: 235F/112C
• Max Coolant Temp: 195F/90C

My best lap of the day was 2:18.900 but my best theoretical was 2:15.764. Lost around 8 tenths on the straight before Lola due to traffic. Then another 5 tenths leading up to the final corner because of the MX5 coming back on track in front of me. Had a few faster sectors on the lap before and after my best as well.

Looking at the data it's clear I am hesitant when getting back on throttle something to work on for the next event.

Assuming the track is damp/drying I am going to set my goal at 2:15 for my next track day. If its a bone dry track and no traffic I think I could get a 2:12

NOTE PPS is the throttle trace

[autoracer86]

The switch from motul gear 300 to Amsoil MTG is complete and man is it good. The car has never shifted better. It's buttery smooth now. Let's see how it feels after my track day but so far I am very happy.

SuperPro rear subframe bushing insert kit
Install wasn't too bad since I had notes from many people who "cracked the code" on installing these without stripping bolts. Took my time and only ever removed one bolt at a time.
Made sure I could tighten down each bolt by hand... If they didn't thread in easy I lowered or lifted the subframe til it did. Feel free to PM me and I can send you over all my notes. Too much for posting here.

As for benefits the rear end feels more planted you really get a sense of what's happening with the rear end. I found it easier to slide around as well.

It's hard to say if it is the inserts or the Amsoil but shifts are just soo good now. I didn't really notice any NVH from these.

With all the mounts/bushings installed I am very happy with the way the car drives and feels now. Time to move on to more performance based mods now

[autoracer86]

Oil changed and pads swapped this afternoon so I am all ready for this Friday. Oh and pictures from the last track day were posted today as well ! Here is the best one I found of my car.

[autoracer86]

Friday was a big success with great weather and a limited amount of cars on Track. I was finally able to get in a few clean laps and ended up setting a personal best of 2:10.0. My Goal was a 2:12 so I am very happy with that.

Well that will be all for now. The next scheduled event is Silverstone in June after that I am hoping to start ordering upgrades starting with suspension first.

Oh and so far so good with the Amsoil in the transmission. No issues on the street or track.

Track Temp 47.3F/8.5C

• Max Speed: 93MPH/149KMH
• Max RPM: 7453
• Max Brake Pressure: 1023PSI Co driver hit 1231 panic stopping due to a bird on track
• Max Oil Temp: 240.8F/116C
• Max Coolant Temp: 195F/90C

Looks like a bit of a bumpy track!

Nice clean lap though, very tidy! What tires were you on?
