Picked up a manifold off 'macboycie' off here for a good price,cheers
Due to me mounting the engine where I thought best I was thinking I would need to modify the manifold quite a lot,but was well pleased when tried it on the car to find just the outlet angle needed modifying
Clears the small angled chassis brace which was a bonus too as I feared it would get in the way,as this chassis was for a Zetec.



Picked up a Westfield silencer at Stoneleigh for a real bargain price of £25 off 'CRAIGR' on here,thanks
Had to shorten the inlet pipe,and cut the down the removable tailpipe that these have as standard and welded it on instead.
Pretty pleased with it,fingers crossed it sounds ok too
Welded two mounting points on,bolted up through the outer chassis rail,using a nut welded onto the top of the chassis.





When I went to fit the tank I was disappointed to find one of the mounting brackets was welded 10mm to far inwards,so got my m8 to weld on a piece of 10mm alloy to save using washers or the like to space it out:

Done some more
I wasn't happy with the amount of bump steer I could see when pressing the front of chassis down,you could see the front wheels moving to toe out quite alot.
After a bit of reading on here rack height seemed to be a problem,so decided to chop the rack mounts and lower my rack to get the track rods running straighter with wishbones,as they were sloping down from mounting points to hubs.
Also the amount of twist on the lower column connection looked wrong imo,so altered the angle of rack while mounts were off.
Before:

After:


Doesn't look much different in pics,but rack has been lowered circa 25mm.Much happier now

Angle on the coupling before:


After:


Another problem I found was with the column support,the Mac1 fitted piece of tube is crap imo,due to the run out on the column the bush was getting tight in certain places.
Also I wanted to use an adjustable column,this would not work with the Mac1 piece of tube idea as it does not allow movement up or down of the column.The MK design is much better,as it uses the full Sierra bush/housing which allows the movement of column in run out and the up and down of an adjustable column.
After research on here I decided to replace it with a bearing set-up

So out with the grinder and chopped off this:


Replaced with this:


Took a bit of fettling,had to cut the brackets,re-angle and weld up to get the correct angle for column.
But well worth the effort!
Can now spin the steering wheel with the column fully raised or lowered and it justs spins freely and keeps spinning around when you loose go of it

Picked up some bargains off the Westfield forum,pair of padded race seats with runners,and a Aero screen,wrong colour I know but for £100+postage I can't moan!

Rolled it out to do some sunbathing today

Did you buy the flared side panels, or did you chop up some non-flared ones?

Cut the fronts off, then swapped the pieces over from one side to the other so you end up with the wide fibreglass at the top, then rivetted some 2mm alloy to the bottom edges to fix to bottom chassis rails.

I used to be indecisive, but now I'm not so sure
