Today i went to the breakers yard to get a smaller steering rack, got one from a Fiat is much smaller and should work, got a few more things. It is hard work pulling the engine and box in and out of the engine bay, i needed a day to rest more to come.

Today started by pulling the engine and making room for the engine to go back in the cockpit, having the weight of the engine and box over the front axle will make the car understeer like the VW's B5 platform, so i found the center mass of the engine and box and will place it exactly over the front wheels and lower in the frame for lower center of gravity, that all will help me to clear the bonnet and will have larger space for the radiators and intercooler, at first i cut the steel and insulation and test fited the engine needed more space, engine out cut the first plastic from the heater box, again test fit still to tight then i cut it all the way to the heater core and cat back the subframe for the gearbox now fits.








This is close to the right place where the engine will live, it should fit under the center console and look like from the factory, the exhaust manifold will have to be modified is very close to the subframe, not a big deal,  may weld the T3 flange now, just to bolt the turbo on when i found a standalone engine management.






I went to the breakers yard yesterday to get a smaller steering rack, got this 3 pumps, couple of high pressure lines, steering rack, i chose this rack because it exits 90 degrees for the steering wheel, in the picture you can see the place where it will live, under the subframe, tie rod ends are very different and will have to make a custom setup to eliminate bump steer, also got two joints for the leakage.

Today started by test fitting a distributor cap, i need to cut little more for the wires to pass, next i remove the exhaust collector i'll need to modify it later, interesting the studs for it are stainless steel, after that i started test fixing the steering rack, i need to cut the subframe for the rack to come through, it will be the lowest point on the car, so i have to make some sort of rock gard.

Today i started planning the cooling system, the lower radiator hose flange, had a broken drain bolt, i had a XU5 flange but it has only 2 small hose nipples,thankfully the drain bolt is the same, so i found new o rings for both the flanges, and i plan to use the original one, but i have the other ready if i don't need all the nipples.





i've ordered this lock cylinders, couple of months back and they got lost in delivery, i've forgot about them and today they arrived, they are a copy not oem, but for the price good enough, the driverside one on my mi16 is broken and they are 25 years old.




I need to found or make new dropped tie rod ends, that need to be drop about 3" any suggestions ???
