A couple of you have asked for more details of my car mods and so here it is and, hey, this area is for discussing anything other than hi-fi, right? I have modified previous cars but have gone further with this one as it lends itself to hugely improving the performance due to a very well designed chassis. I now have a very well sorted sports car with terrific handling, mountains of grip and rapid (but not silly) engine performance, now running at 300bhp (the stock car was 200bhp). It has completed 112k miles and still runs smoothly and reliably, testament to its high Japanese build quality.

"testament to its high Japanese build quality?" Much more a testament to your attention to detail.
I'm starting to think that you will be missing your daily commute once retirement kicks in...

^Oof...will have to find another way to get time behind the wheel.
Is it possible to quantify how much these performances enhancements have increased the enjoyment of the ride?
How is that android head unit working out? Is it pairing with phone?

I bet if you fit a grounding box to the end of the exhaust it will reduce the noise too!  My elderly Jaguar XJ6 (Series III, 4,2 Litre Sovereign) has had a quite a few modifications done to it over the nearly 30 years I have owned it. Various upgrades have been applied to the suspension over the years and the transmission was changed from the old GM unit to the later ZF unit, designed for the AJ6 engine, using a special bell housing designed to couple with the XK engine. It has a Torque-lok differential fitted and higher gearing than standard. The original LE Jetronic fuel injection system was replaced with a fully mapped system using 6 coils and sensors and the inlet manifold was changed to a fully changed unit as was the exhaust manifold and re-mapped for fast road use. The crank has been modified and the head ported to take larger valves and the engine runs on a D-type inlet camshaft, but a standard exhaust (I had both changed to D-Type at one point, but the car was not really suitable for use in traffic after that and so one was changed back to a high-lift standard cam.). The cooling system was modified to cope with extra heat output and various upgrades have been made to other ancillaries over the years such as the alternator, lighting and bits of instrumentation. The bodywork and chassis etc have been restored twice while I have owned the car (the last time about 10 years ago to a very high standard) and the interior has been refreshed although much is still original and is in very good condition. I used to use it daily at one time, but now it spends most of its life in secure storage and only comes out for the odd special occasion and holidays (actually just as I finished typing I received a message from the tracking system reminding me of its current location - it must be bored!). |

Hugely, is the best I can do (that's qualifying it, not quantifying it). The stock car performed very well overall, it and the Mazda MX-5 being in a class of their own although not really overlapping with each other too much. Now, it's far more precise with a firmer ride and very fast turn-in. Acceleration matches a Cayman, which is good enough. The Android head unit is a bit elderly now (running Android 9) but certainly links with the phone and I have steering wheel controls for volume, app switching, navigation (Waze), digital radio, Qobuz etc. |

Very nice, Pete. I'll bet its reliability has taken an upturn, especially with the replacement injection system. I am lucky in that the Toyota provided D-4S injection system is both direct and port, so the valves stay clean. Is a D type camshaft one with large overlap of the lobes? That would be horrible in traffic. Have you toured it around the country or on the continent? |

It's a beauty Martin and immaculate .
I've just bought a Subaru , before you get too excited it's a Forester XT , last of the MK IV's before they went hybrid , 2.0l Boxer engine , I love it .

The engine is a flat four beauty. Very smooth running with a low centre of gravity.

That would be horrible in traffic. Have you toured it around the country or on the continent? A bit more lift and a different profile which would give slightly extended dwell. The larger valves and followers probably do most of the work and the latter are needed to cope with the parabolic profile as I understand. Although they are nowhere near as aggressive as race cams, when used for both inlet and exhaust they narrowed the power band making the car less than ideal and pretty lumpy at lower speeds. Interesting off-beat ticker though and it sounded pretty glorious when revving, but on a big saloon it was hard work. Only in the UK. Urban cycle is about 16 mpg although it will do 26 mpg on a decent run and so one has to factor that in when planning a holiday. I always planned to take it to Switzerland to visit friends as fast 'A roads' suit it well and it is surprisingly agile for what was once considered a large car and the alps would be fun. I doubt I will now though. Next decent outing will be South Devon in July for a week. |

Speaking of mileage, the stock BRZ was 35mpg and with the supercharger I'm getting 32mpg. I consider that to be rather good for the power uplift.

Lovely mods Martin. I am past it myself, having enjoyed decodes of modding motorbikes and cars, and crashing them…
But after sitting in my son’s 6.3 litre biturbo I finally realised that he inherited the need for speed from me after decades of being driven around by me. Has your son also inherited the upgrade bug?

Has your son also inherited the upgrade bug? Sadly not, Stan. He doesn't even have a driving licence, a result of living in Bristol. He does rather like my car, though. |

I changed my thermostat to a Mishimoto 76°C one to better suit the supercharger. This was first researched and developed by Cosworth as a supercharger solution for my car model and it definitely gives a little more pickup and punch in the midrange. I'm noticing that the car's heater doesn't pump out roasting air as before, but there's still no problem warming up the cabin in these temperatures.
