Supercharged Toyota GT86 TRD Edition

[TRDness]

Hi everyone. I’ve decided to make a build thread of my 2013 GT86 TRD edition, a lot of work has already been done to it so I thought I’d share its progress so far. The GT86 TRD is a special edition in the UK and 250 were made for the country, it comes with the Japanese TRD body kit, TRD TF6 wheels, and a variety of other TRD upgrades. I have built the car to be TRD themed visually but it also has a lot of other quality aftermarket parts where you can’t see! I’m based in the UK where car modification to this type of car is less popular than in the USA due to insurance costs and the general fact that parts are more expensive to source due to tax, but that doesn’t put me off! I have spent the last year modifying the car in preparation for track use and forced induction, and it is nearly complete. The car now runs an estimated 300 horsepower at the rear wheels and weighs in at 1250kg.

Looks great, some tasteful mods and it looks very well finished too. Must have set you back a bit?

[TRDness]

Thanks a lot! Yes it has, but I'm happy to pay the price, I have a passion for this and love getting into the technicals of it. I've built the car to be a brilliant all rounder, but the handling is where it absolutely excells. Now that I have the supercharger installed it has the power that the chassis can easily handle and it's what should have come on the car from the beginning in my opinion.

[TheLordJohn]

Top effort. Looks like some top quality parts and work have gone into that.

[MrMoonyMan]

Really like that. Done exactly right. Nice.

• In before the idiots who will talk about broken suspension and don't know who/what TRD do....*

The car looks excellent, the spec is very tasty (you can't really go wrong with TRD kit) the 5 spoke slightly dished alloys look far better than the originals and the polished multi spokes you had fitted.

I bet it's a hoot to drive!

Looks great! The TRD body kit was always let down for me by awful plasticy wheels and the fact that it didn' have the go to match the show, you've tackled both issues head-on there, that style of wheels looks great on the GT86 and the pearl white paint shows off the front and rear arches very nicely.

Not sure how much time you've had behind the wheel, but I'm interested in how it drives now. Is the ride bearable on bumpy urban / B-roads? (I've had bad experiences with coilovers in the past). When it breaks traction, how controllable is it? Does the power come in all at once, or progressively?

[AmitG]

I really like this. Well thought through and very tastefully done IMHO.

I love the triple gauges on the passenger side

I am really tempted to get a GT86 and have it supercharged. The more of these I see, the more tempted I get.

Question, what sort of performance do you get now? Can you quantify it?

[Butter Face]

Gorgeous. Absolutely love it.

Yes I agree, I liked it when I first bought the car but it became a bit too blingy for me over time, I'm not one to have something that looks fast but actually isn't.

I've driven this car pretty much everywhere imaginable, and the coilovers perform very well indeed. Damper adjustability is a must so you can tune out understeer and balance out the car in the corners, but of course it also gives you the ability to soften them up if you intend to just cruise around. I have them on full stiff back and slightly softer on the front to reduce any understeer and promote slight oversteer, with this set up it's actually comfortable to drive around in on normal roads. The TRD coilovers come with road springs and 3 racing spring options, I have the softest of the 3 racing springs which is intended for road/track mixed use. B-roads are absolutely fine, when they get bumpy you can end up bouncing around slightly inside, but nothing excessive and well within my comfort zone.

In terms of power delivery it's a centrifugal type supercharger so it really depends where you are in the rpm range, boost really comes on above 3000rpm and the power climbs endlessly all the way to redline at 7650rpm. If you're anywhere in that range the supercharger will react instantly and give you all it can give if you desire it, so smoothness depends on throttle input and is easily manageable. I have sticky 255 tyres on which are pretty hefty, and it will break traction in 2nd and 3rd in a straight line in the wet. In the dry it launches perfectly and there's no traction breaking in any gear apart from first.

When the car breaks traction it's easy enough to control, as long as you're sensible with your throttle inputs. Part of the reason is that this car even from the factory gives a HUGE amount of feedback straight to the seat and steering wheel, so you can always feel exactly what's happening. However it will bite you in the ass and spin out if you put too much throttle in, and likewise if you let off too quickly it'll snap back the other way. It's all about smoothness.

Thanks a lot i haven't done a 0-60 just yet but if I were to quantify it using other cars, it's slightly slower than a bog standard M3 in the straights (the power to weight is about the same but he has more torque under the curve in the lower rpm range), but chasing round the corners with the M3 I find myself having to let off a bit as he can't take the corners as quickly. Around the track I'd predict that we'd be equal.

How it should have left the factory, brilliant.

I see these a lot here, though I hate the scion badge. Yours looks just right.

Thanks, are you from the USA? Over here in the UK they're Toyotas so happy days.

Seconded. Now get out and enjoy it

A little visit to Fensport in Chatteris where my car meets its racing brother!

[GregK2]

Incredible 86 you have there. I love the shot from the rear especially.

[SepticTank]

I love what you’ve done here. I have an Aussie GTS86 spec auto (no exact equiv here in the U.K.) that I bought when living out there and brought back with me beginning of last year.
I had the great guys at Fensport fit an HKS S/C and Cobra catback resonated last year (with all the various trimmings needed) and ECU remaps done. I love what it’s done to the car. First thing I said was “that’s how it should have come from the factory”, so we are in the same mind there.

This year I’m finally in a position to finish off what I started with suspension, tyre, and brake pad/lines upgrades. Plus I will look into what brace bars etc. would be useful and worth the money. I know that the GTS brakes are an upgrade vs. the standard GT units. Not sure exactly what the difference is. With that in mind I will probably keep the same callipers etc. as I can’t see the point in spending the best part of £4k for little difference. I will probably track it only 4 or 5 times a year, so it doesn’t need to be full-on race-spec. As long as it is safe that’s the most important.
I’m also going to complete my audio and soundproofing installation. I put a wonderful Apple CarPlay head unit in, and a Thatcham Cat 1 alarm/immob last year. Just didn’t have the money to replace all the stock speakers etc. and carry out a comprehensive fit of soundproofing all round the car. I think doing this will make a huge difference to the quality of sound, as well as cut down the drone from the exhaust on long motorway journeys. How anyone manages with a non-resonated system I have no idea. I severely upgraded a mini (1275GT) some years ago and put on a straight-through exhaust. Couldn’t hear myself think after a couple of miles on the motorway, and after 10 began to get severe headaches.

Like you, I prefer my car to look as standard as possible from the outside and like to hide all the mods away. For one thing, having less on show reduces the risk of some arse stealing it for a joyride, and insurance is expensive enough already. It’s been fun so far, on the odd occasion that it’s happened, to really confuse those that have attempted to drag race from lights, or go for a race down the dual carriageways and A-roads.
I’m planning on a day or two at Santa Pod later this year, especially once everything is finished and bedded in. My partner and I are going to go up there and do a few runs as a baseline, and then some more during and after the mods, to see what difference they’ve made. She’s really looking forward to it as she’s never been before. I will have an EcuTek ProECU kit by then, so I’ll be able to load up different maps and then test them straight away on drag strip to see how they are. I want to get some with pure straight line 0-100mph, and others for track use. And then some that will be the most fuel efficient for motorways with an auto. When I’ve selected the best 4 maps I can load them up in the four slots available on the car. It seems much better to me to do things that way, compared with rolling road testing with is more expensive and a lot less fun. I know Fensport will work with me to provide me the maps I need. They have been totally top notch and excellent to deal with so far, and did an awesome job on the work last year.
Then I’ll just enjoy the odd day at Goodwood (which is my closest track). Plus I’ll take more of an active interest in the owners’ club scene too, with some track days as and when they occur.
This coming week ‘Lola’ (the car’s name, not my partner’s ) is getting new rubber and she is totally looking forward to it. She’s been on the same tyres since new so time for something more sticky.
I’ll read in more detail the exact changes you’ve made to date and will send you a message with any specific questions I have if that’s OK with you?

Good luck and well done, love your work

Rather than dig up old threads, why not start a new one with your car ?
