    Rest of the install was straightforward. There was a 13 mm thick spacer in the caliper that also provided radial mounting holes, but I removed it. The mounting bracket I made is simply a 3 mm thick steel plate, drilled in the right places and trimmed to size. It mounts were the 13 mm spacer was, together with a stack of washers that positions the caliper in the right position, the outer pad close to the disc. I went to the local hardware store and got 3mm steel cable and the guide wheels. The cable will go from left to right like original and through the original guides so the rest of the handbrake system doesn't need to be changed. Works very well, very solid, great clamping force, confidence inspiring. Another problem solved.

    I leave the caliper blank aluminium, you have to really look to notice it, maybe if I paint fake holes on it it is even more camouflaged.

    Nice, now jump on the lathe and make spacers (which I would weld to you mounting plate, then you can never loose them) to replace those stacked washers and shorten the bolts ... :).

    I made new mounting brackets for the handbrake calipers that move the caliper a little higher so the cable runs a little more like original. Also I got cast metal guide wheels instead of the plastic ones. And I found proper shorter bolts...(the original ones don't have enough thread to shorten them)

    I found a drive pulley for the supercharger. It is from a 540-740-840 BMW and has 7 grooves, the SC has a pulley with 8 grooves but I couldn't find an 8 groove pulley.

    Then I had to design an adapter to mount the pulley to the crank harmonic balancer.

    A local machinist made it for me, he changed the design a little to ease manufacturing. I will fit dowel pins at the crank side to prevent slipping.

    Testing the injectors. I used an easy bleed brake bleeder kit for this. The bottle is filled with fuel and pressurized through the valve of an inflated tire. Works great but one injector wasn't spraying and shutting off properly so I ordered 2 more from a specialized Saab wrecking place.

    The carb cleaner I used in the ultrasonic cleaner wasn't to kind for the black paint on the injectors (and the plastic lid from the cleaner). Got new caps, filters and O-rings.

    I ordered new 60 mm springs because I found the Superformance set (though stiffer than original) still a bit to soft, the Koni shocks can handle much more. These are 12 inch 250 rated rear and 10 inch 300 rated front.

    I converted the spring platforms on the shock and made the front ones height adjustable by using M20 nuts and threaded rod. I won't adjust them by threading in or out though, but my making a rod of the correct length that is fully engaged in the nuts.

    I still found the rear springs to soft because when the car is pushed down it raises back only slowly, very scientific. So I ordered 350 rated springs and these are already installed and now when pushed down the car raises back quicly to original height but not passing the original height and swing back.

    There are cheap sets of height adjustable coil over shocks like QA-1 but I have more confidence in the Konis. A good set of shocks will cost more than 2000, maybe in a year or 2 when my finances are recovered. By the way, Koni fired 320 of it's 480 employees recently, get those original shocks while you can!

    I changed my mind again, like many times during this project. I decided to remove the brake pressure difference warning device and route the lines straight from master to caliper, the master cilinder I have now has 3 outlets were the original has only 2. The pressure difference device is not a pressure limiter/brake bias valve for the rear brakes, this car didn't have a brake bias valve installed. The 308GT4 should have one according to the workshop manual. Now with the bigger brakes I have I thought it would be wise to install one and I ordered one from www.compbrake.co.uk . I checked how the valve was build up and thought the lower port would be the inlet. I was wrong though and in the picture it is connected the wrong way. The knob can be reached through the battery cover.

    I used the original brakeline that goes from front to back and made all the others new from cunnifer (copper/nickel) but felt a little unconfident. The original steel line I had to straighten in some places and bent in others and you can bent them only like 5 times before they break and it is 30 years old. And though cunnifer is good, steel is better but to tough to make flares with the simple tool I have. Then I found a german ebay seller that sells ready made steel lines in a lot of lengths and I ordered all the lines I need, 14, that includes the 4 lines on each caliper that connect the caliper halves and the 4 short lines from flex line to caliper. When they arrive I can finally fill and bleed the brake system. I ordered a new vacuum servo hose from superformance but unfortunately they don't sell these anymore.

    I am planning the side air inlets on the car to bring air to the intercoolers so the original oilcooler would be sitting there without much air flowing to it. I bought an aftermarket oil cooler with the intention to mount it to the rear of the car behind the exhaust cans, there is room now with the 2 smaller cans on top of each other.

    That is a very awesome project. Not sure how I didn't see this before. The GTO is a gorgeous car and a very good choice.

    Whenever I have some spare time I am straightening the body, a lot of hard work sanding by hand. The black is guide paint.

    I have some holidays soon and hope to have the car painted by week 34. The engine back in, rewiring and trying to get this thing to run.

    Hi Bert,

    That's a lot of work done again, amazing stuff, as usual.

    A few comment, not meant to discourage you or badly comment on what you're doing:

    Rear quarters: You and I know that like this it looks cr*p. Now is your chance to do a proper job (since you've been in there with the grinder anyway) to make a seat and plexiglass ones wich will open up a vent like in the real thing. You will want more air into the engine bay anyway.

    Front lower a-arms: It looks like the shock/spring has a much lower angle than original. If this is the case, your spring ratings won't mean much, and I am worried about the loads and wear on the shock. Do yourself a favour and extend the shock top mount outward to restore the original angle.

    Radiator: I don't know what the experience with others is regarding the capacity and uprated engines. I also don't know if you can make a 328 rad fit, but I'd look for a slanted radiator. The 308 rad is good for cooling in our African climate, but I have no idea if I'd bump the power of my car to 300 or more HP how long it would take to overheat the engine. Rather be safe than sorry.

    Btw, I may have an interest in the standard injectors.

    Keep up the great work, she's starting to look like whole. I like the vacancy left by the ugly lip over the windscreen!

    Wish I had your skills and guts,

    Jack.

    I don't think i would worry about the radiator that much.

    Your cooling system load is mostly a function of cylinder wall and head combustion chamber surface area. That doesn't appear to be changing. Even though the engine is capable of more power, it will not take/use/produce anymore power to cruise down the road at 100, or even 200, KPH now, than it did before.

    Perhaps if the car is being run at max power output for some time (Daytona speedway), the rad may be insufficient, but for normal driving with the occasional full throttle burst, I see no problems.

    I am impressed with this project. We do it all the time over here on old (and newer) Fords and Chevies, but I have never seen a custom hot rod Ferrari done before.

    Thanks for thinking of me Bert, but I'm all set on injecters.

    I have to control myself on spending money on good stuff cheap. I'll never get my motor done. LOL!

    Great work buddy. :)

    I first brought out the window even more and was trying an aluminium surround 20 mm wide 2 mm thick, but that didn't look right, 2 mm is too thin. I will leave out the rubber mount and make a 10 mm thick surround (black of course) and louvres over the fuel filler like a GTB. The GTO vent is too complicated to make with difficult cutting and welding in a rust prone area and I don't want to move the fuel filler because of all the extra work. It will look ok eventually.

    I had the same doubts before I started and wanted to bring out the upper shock mount but then did the calculations and the difference is only 6%, originally 10 mm wheel movement is 5.6 mm shock movement, with the longer arms it is 5.3 mm. And I have a 300 rated spring now, original was about 200. The shock I have adjusted stiffer almost to the max and dampens the spring perfectly. There is no extra load or wear on the shock as the force on the shock is only a straigt line from upper to lower mount, it is not a McPherson strut were there is side load on the shock.

    That was my reasoning too. I have the german Autobahn nearby were you can go flatout if you want but the car is on the rev limit at 240 km/h and that hasn't changed.
    The SC is only for extra acceleration and you can only accelerate for a few seconds each time (it will reach the 240 km/h within 10 seconds from a standing start haha).

    It just came to me that it'll always look a little strange since you will be missing the doorglass-frame to mirror on. In any case, it'll look a lot better than with the louvres cut out of the flappers and the deeply recessed glass.
    It may be worth rounding the surface of the trim somewhat to make it appear less 'stuck on'.

    I never thought you'd type something as 'too much work':)
