<br><font face="Arial,Helvetica"><font size=+1>This project is my long
term effort at achieving what I consider to be the most affordable way
at getting the most performance, handling , drivability, and looks that
you can get in a street car. Yes , you can get newer cars such as the current
generation RX-7 , but this car is much cheaper to build , and by the time
I have finished , will outperform it in almost all aspects, except maybe
the looks department. Aiming for eventually 800HP on the street but I think
650HP is more than enough , it is hoped to be one of the fastest street
cars getting around. Not only straight-line , but point-to-point as well.

RX-7 Diary</font></font></font>
<br><font face="Arial,Helvetica"><font color="#000000"><font size=+1>I
am now keeping a log of all changes done to the car , so you can see how
much work and time goes into doing a project like this.</font></font></font>
<p><font face="Arial,Helvetica"><font color="#000000"><b>22-06-99</b> :
I have been experiencing a problem with fluctuating fuel pressure for the
past month or so.&nbsp; I pulled apart the Malpassi Fuel Pressure Regulator
and found nothing wrong , put it back together , upped the pressure to
62psi static , and the car is running fine now after a few minor ECU changes
to suit the pressure. Don't you hate these little gremlins...&nbsp;&nbsp;
:-)</font></font>
<br><font face="Arial,Helvetica"><font color="#000000"><b>23-06-99</b>
: Had a small split inside one of the stainless braided water lines for
the turbo.&nbsp; I managed to get my big clumsy hands down to it and pull
it off , repair and replace.&nbsp;&nbsp;&nbsp;&nbsp; Went for a drive to
test a few things out , but with wet spots on the road from the rain it
was a bit dangerous to do any real testing.</font></font>
<br><font face="Arial,Helvetica"><font color="#000000"><b>24-06-99</b>
: I will be doing some lambda probe testing on the engine tonight to fine
tune the changes caused by the fuel pressure difference. It is running
a little rich at the moment which at least will not do any harm.</font></font>
<br><font face="Arial,Helvetica"><font color="#000000"><b>1-7-99</b> :
Finally have the new turbo that will unleash some of the power potential
of this engine.</font></font>
<br><font face="Arial,Helvetica"><font color="#000000"><b>17-7-99 : </b>Due
to a split sump and loss of all the engine oil , the triple rotor seized
a bearing onto the crankshaft.&nbsp; The engine is now out&nbsp;&nbsp;
(Pics and story <a href="damaged1.htm">HERE</a> )
, and repairs are being undertaken.</font></font>
<br><font face="Arial,Helvetica"><b>4-8-99 : </b>The engine was stripped
down today by Bill Nabhan at Mazsport.&nbsp; A seized and spun front stationary-gear
bearing is the culprit , with the rest of the engine looking like new.
Lucky....</font>
<br><font face="Arial,Helvetica"><b>20-8-99 :</b> I decided to get all
the engine parts either pollished or chromed while it is apart. You name
it , it is being cleaned up. It should be a couple of months , I guess
, before it is all back in the car and running again.</font>

<p><font face="Arial,Helvetica"><font size=+1>So , you want to know what
it goes like ?&nbsp;&nbsp; It pulls incredibly hard from around 2700 rpm
through to 6500rpm before the turbo becomes a big restrictor. In it's powerband
, however, it is an absolute rocket ! With it's tall diff ratio ( tall
for a rotary ) of 3.45:1, it really gets some speed up in each gear , yet
still revs very fast. It makes the speed very deceptive and you can easily
believe you are not going that quick. That is until you back off and realise
you are doing well past 200km/h in no time. It will easily pass 300km/h
no sweat.&nbsp; In it's current state of tune , it should still be capable
of low 11 second quarter mile times in the 125-135mph range, but please
remember that this car was never intended to run the 1/4 mile. It does
not get much in the way of traction in the lower gears , and as such it's
times would be a lot slower than it is really capable of. So do not ask
me what I think it will do on the 1/4 mile as I am not taking it down the
track. Although it is slippery off the line, the upper gears are mind-blowing!&nbsp;
I need traction big-time now...</font></font>
