I will be updating this page on regular basis as soon as
something changes (hope I will be able to afford modifying my car regularly). I
will keep my old mods in this list (in italic), it is interesting to see car's progress.

Sorry, no ICE here
My 1989 mk3 Toyota Supra turbo was purchased in May 1999
with 119000 km on odometer. I was the second owner in Ukraine, originally car
was imported from Germany. I can't say exterior and interior were in mint
condition, low odometer numbers were most likely the result of pre-sale
"adjustment". I was very much impressed by Supra performance, maybe because my
previous car was 1989 2.3ltr Mustang (don't laugh, I was always and still is big
fan of American muscle cars, but in the mid-80's I was only able to afford that 90hp
"monster")
Looking back I consider myself lucky, I had the choice between N/A and Turbo and
main reason I bought Turbo because it was black and was on 17" OZ wheels. I knew nothing about
turbo cars and their potential, but not for long. When my ship was in States (I
work as marine engineer for living) I bought few issues of Sport Compact Car
magazine and was amazed by possibility to double or triple turbo motor
horsepower. So, when I was back home for vacation the search began. First I
found SOGI (Supra Owners Group International) and subscribed to e-mail list.
Nowadays it is nothing special to have 350-400whp mk3 Supra, back then not so
many guys were pushing this kind of power. I was hooked and decided I need
around 350whp and supporting suspension mods to be happy. Now I realize how
wrong I was. Like my friend says the only cure for speed and power addiction is
the lack of funds ;-) It is never enough... The same summer
2000 I placed my first order with Suprasport, it was K&N FIPK, Suspension
Technique lowering springs and NGK plug wires. I lowered my car, removed cats,
installed K&N, added few washers under wastegate actuator bracket and wow - that
thing moved really fast!. I felt like the king of the street. Some time later I
of course realized that stock mk3 despite decent power of 235 factory horses was
too slow off the line due to it's mammoth weight of 3600lb (1620kg).
I became customer of suprasport.com for many years. Former owner Jeff Montigny (aka
Mr.Boost) is great person, one of the founders of SOGI, he contributed a lot to
Supra community. Now he is retired from Supras thing, has wife and two kids, got
decent job and drives 911 Porsche. I still see him sometimes posting on
Supraforums.
OK, back to my Supra. I don't want to be too long here, all aspects will be
covered on other pages of this site. I am sure many people will find some mods
and especially interior condition too "ghetto style". There are few reasons for
this. First - due to the nature of my work I spend only 3-5 months of a year at
home. I always on vacation in summer and don't have luxury of long winter months
when people tend to tidy out their cars. Second reason - if I have certain
amount of money to spend on my car I better spend them on performance mods rather then to improve
appearance. And reason no.3 is almost all appearance mods lead to weight
increase. If you continue reading on this site you will see that my car is on
hacksaw diet.
Hope you will find this site informative.
