GR86 Importing my 2023 JDM BRZ

A friend of mine directed me here to read all about this car ! Wow what an amazing story this is to read absolutely gorgeous 😍
 
Decision made - I have ordered a set of WedsSport SA-75R wheels in 18 x 8.5 ET45. They will ship from Japan so it'll be a wait, but I'm always patient with these things. They should look great on my Sapphire Blue BRZ.

I can transfer my nearly new 225/40 Goodyear F1 tyres (which are superb) and consider going up to 235/40 on the next change if I so wish.

Nice Martin, good choice.
Whats the weight of these?
 
Exciting. For your reference, an ex-owner with 225s on 8.5. He has a more aggressive 35 offset though, but you'll be able to see the tyre fit on the rims.

Hello Martin, how has the reliability of your car been (before and after mods). As you may know, mine it’s on its way from Japan…considering dailying it, all ok?

Hi Tony, it drives like a dream - really. The car is OEM like in smoothness, with far more pull once over 3,000 RPM. It's linear, with good pedal response and there are no glitches at all with the excellent Fensport tune. My Scangauge reports zero knock events and all four roughness indicators are also at zero. No problems with the clutch, either, and I am sensitive to wear as I had to replace it on my old BRZ soon after the Harrop supercharger went on.
I daily it and have done lots of longish drives including a trip to the Ardenne Forest in Belgium during a very hot heatwave week. Not a single problem and no overheating. The secret is to give it the best oil you can and only use good fuel - Shell V-Power 99 for me.
 
That’s great - just need to find a good / sympathetic specialist for services near me then. Thanks mate.
 
I went back to Fensport yesterday for some more HKS supercharger optimising. Ecutek for the JDM ECU is still immature and everyone is still learning. We opened up the HKS restrictor from 45mm to 47mm and then road tuned. There was still more to be had, so back to the workshop and opened the restrictor to 49mm and did more tuning. Then, Adrian said "let's just get rid of it" which surprised me as everything I had read said not to. So back to the workshop, took it out and back on the road.
Finally - the animal urgency I had been looking for with terrific midrange pull. 325g/s airflow for about 330 crank bhp but, more importantly, the pickup and grunt is superb.
So, HKS GT-2 users, you can, with a good tune and stock airbox, run without a restrictor, with the stock injectors still having headroom. No knock, no running lean at high RPMs, just strong pull to the red line. I still set my rev alarm at 6500 RPM and change as there is plenty of pull throughout.
I am very pleased with the result. Nice one, Fensport!
 
Sounds like a lot of fun. HKS supercharger seems to be the go-to bang-for-buck performance mod in the UK. 330 crank seems a bit more like it. I thought the 380 you said last time seemed a tad optimistic on the stock clutch and fuel system. Any plans to get it dynod? not that it really matters. I'm mostly curious as to whether the extra cash spent on turboing is worth it or not.

I'm considering taking my car to Fensport to add boost control and try out one of their tunes and an uprated clutch. They aren't advertising custom turbo tuning on the website yet though. Maybe I should just ask them via email. My tuning Developments tune feels great for the most part, but the rev hang is still there and it drives me mad sometimes.
 
Yes, the 380 was based on the wrong data, then corrected with info from Adrian at Fensport and Mark at Abbey.

I don't really need another dyno as it's just an ego thing and my 'butt dyno' tells me it's really ripping now. I may ask Abbey to run it again but no hurry at all.

As for turbos, I've had supercharged and turbo'd cars and I definitely prefer the characteristics of the former. I really dislike lag - people say some turbo installations have no lag but I'm not fooled by such claims. Even my twin sequential turbo BMW 335d had lag! There is nothing quite like the instant pickup and sharp throttle response of a supercharger.

No need for Dyno my friend , next month should have some interesting data :p:eek::eek::p
