166 24v into 116 GTV
Posted: Wed Oct 03, 2007 10:51 am
After a slow start in this years race season in the 'budget race' car as shown in race and track section , I wanted bigger and more power full motor to put into the race car. I needed something to make up for total lack of drivers skill to put me in front of the all Alfa Romeo field in the only GTV 6. Even though I am running a totally stock 2.5 12v motor ,I figured I must be ahead of atleast half the four cylinder field hence the search for a new motor.
Luck had it for me that some chap(unlucky for him) rolled his 166 (30 000KM ON CLOCK) and the motor was going very cheaply. I managed to swop a spare automatic 164 box plus other spares to this garage for this motor.
My plan was to leave this 24v motor standard and just fit some 'wilder' intake cams.
In between racing and the 3.7 project I decided to do this project as fast as possible but for some strange reason this has dragged on for the last four months. Main reason for is that I have gradually improved my driving and got my budget race car realy set up well and started getting some good results. I have also grown attached to the sound of the 2.5 12v motor and the reliability it has given me after ten hard races, many practise session and a few track days.I have no idea how many km this 2.5 12v motor has done but it just seems to rev free'r every race. Anyway the 166 engine is now finished and ready to go into the car but I want just one more race with the old motor before the swop.
I have put this in performance as I have a few interesting pics on this conversion which might help others who might try the same thing.
As the 166 had rolled my first step was to remove the heads and sump(remove journal caps) to have an inspection that nothing major had happened to the engine.
All looked perfect so next step was to send the intake valves in for lenghtening this time, to suit the new higher profile cams. The valves and cams were done by SA's leading motorsport team( BMW). The valve seats remained constant(measuerd clearances before) so the lenghtening of each valve was the same if that makes sense. On went new head gaskets with new tensioners,belts and waterpump . The 166 tensioner is a pleasure to work with and twenty mins later with cam blocks all is done.
