No doubting the car looks good and the mods are well balanced but between £35 and £40k in total. Your mental!
That's GTR/M3/911 or of you like the lightweight and big power TVR/Lotus.
Lovely car though and don't take my post as negative.
That is of course assuming I want a GTR/M3/911/TVR/Lotus That's GTR/M3/911 or of you like the lightweight and big power TVR/Lotus.

After having worked for Toyota for over 24 years, I am afraid that I am somewhat biased I definitely don't take your post as negative. As I posted before, I am modifying my car to a specification that I want - sod the costs

Top work! What happens with the warranty?
I don't have my service book with me at the moment,(it is in the car at Fensport), but from memory, when I read the wording of the warranty, it stated something about the warranty being voided if any failure was as a result of any modifications / changes made. That said, there was no way I could wait 5 years before starting to make the changes - the 5 months I waited was long enough 
Brief update.
my car is now on the lift at Fensport for the instillation of the turbo kit
Inlet pipe and air box removed
I will update the progress as and when I get more pictures through from Adrian@Fensport
Again, thank you everyone who has taken the time to post for the great comments

How does the engine hold up to boost? What compression ratio is the engine already, and are the pistons/rods able to cope with that sort of power hike? If you blow it up - will you rebuild with lower compression pistons and new internals?
Sorry for all the questions - would love one of these if it had more power.

AMAZING! What sort of power increase do you think you will get from the turbo upgrade? Sorry if you have said it already, I have only looked at the pics in the thread.
Thank you. Expectation is circa 285bhp with 8lb boost. What will be equally great is the increase in torque, hopefully an extra 100 ft/lb at 3600rpmzabba said:
Wow, very nice. So an expected 285bhp should give it around 230bhp/ton, that's much more like it.
Thank you for the nice comment. I totally agree - should help to prevent being embarrassed by various hot hatches and diesel rep mobiles stuart-b said:

By all accounts, the engine holds up very well, certainly at the (relatively) low boost level I will be running. There are a number of cars in the USA running 400bhp+ on the standard internals, there is one company that have achieved over 600bhp on a standard engine. The compression ratio is 12.5:1, so very high for a turbo engine, although it does have both direct and port injection, as well as a very good design combustion chamber (developed by Toyota with the help of Yamaha). These factors all help to minimise the potential for detonation. Shell V Power only will be used as well. I think the key will be very good mapping, and here I have total confidence in Adrian@Fensport to look after me.Sorry for all the questions - would love one of these if it had more power.
Should it blow (which I sincerely hope does not happen
,) I will most probably re-build with forged rods and lower compression forged pistons. http://www.fensport.co.uk/Parts/Model_108/Category... Carrillo make forged H Beam Rods for the engine.The chassis of the GT 86 is so good, that in my opinion after 10 months of ownership, it definitely does need more power! A 50% increase should just about do it

Thanks - what a brilliant engine. Toyota did it again (Like with the Supra!) Enjoy, and keep us posted!Should it blow (which I sincerely hope does not happen

I obviously will be fitting a boost gauge, and in order to provide an additional level of protection, I have decided to go with the AEM Wideband Failsafe gauge, which is a combined Wideband Air/Fuel and Boost in One Gauge. In order to keep the stealth look, I will be fitting it in an adaptor that replaces the vent to the right of the instrument panel. The vent remains functional, just with the gauge in the middle.
The gauge is a really clever bit of kit, in that not only does it provide the boost and air / fuel ratio display, it also acts as a data logger, saving the previous 2.5 hours worth of data, that can be downloaded via a USB connection. in addition, it can be programmed to activate a failsafe strategy in the event AFR falls outside of a user-defined operating window. If the AFR falls outside of the set operating window, the Wideband FAILSAFE Gauge triggers a user defined output function that will hopefully save my engine from catastrophic damage.
