This is Mark Rogers MR2 Turbo. Not that you would
know it, it is a 1990 Rev.1 model. However Mark has taken the time
to face lift it to the 94+ spec, with the addition of later rear
lights, wing and aerial. But it's not just all good looks, with the
work that he has done on the engine too, he would leave most things
for dead at the lights!
He starts off by saying that he first replaced the
standard fuel pressure regulator with a FSE power boost valve, when
his standard one gave up on him. He said the car felt flat when he
got it and the biggest performance increase was when he fitted the
bleed valve. The trouble with the MR2 Turbo, is that it has lots of
safety devices to protect the engine. The first is the Fuel cut.
Let your boost creep up to 12Psi, and then the fuel pump cuts out!
Mark over came this by fitting his own Fuel Cut Defender, which cost
him 8p from Maplins. The second biggest problem is the Turbo VSV
that Toyota fitted to allow the car to limit the boost. Basically
you can put your foot down one minute and have 15psi, then the next
time you can have 7psi. With the bleed valve in place with the VSV
he was hitting boost from 11 - 17psi, when he was after 15. This
was over come by removing the Turbo VSV and fitting a Grainger Valve
from Dawes Devices.
The Grainger Valve is like a bleed valve, but it
uses a ball bearing system to hold the waste gate shut, right up
until the point that the set boost is reached. This means that
turbo lag is reduced, and you hit your set boost every time!
Mark has also installed a boost gauge where the
ciggy lighter used to go, at the moment he is running 0.94bar boost,
which he soon plans to up to 1 bar. Other engine mods include NGK
spark plugs, Magnecor KV85 racing HT leads, Apexi POWER air filter,
a Uni-Chip, and next month a Spearco Intercooler and water
When he got the car is came with a single exit 5"
HKS pipe, which he has now replace in favour for the Mongoose
system. Because the Mongoose system has less back pressure, he
needed to turn down his boost slightly to stop the car from over
boosting. Mark also has a Blitz Dual Turbo timer. This clever
device shows peek boost, instant boost, and has an auto or manual
His wheels you see are 17" League 088 wrapped in
Falkon rubber. Their good in the dry he says, but not too great in
the wet. During the snow the grip was so bad that it got to the
point of having to ask a lorry driver to move his lorry before he
slid in to it!
Anyway I will leave you with more
pictures and a tech spec at the bottom. Enjoy!
