Mike, I've welded cast AL parts before, it is rather tricky. The 'pot metal' , or low grade AL that carbs are typically made from tends to turn to liquid much faster than good AL. The trick to welding it is to use bursts of a lot of power, to localize the heat. A square wave TIG would be a must. -Les

Thanks guys, I do need some ideas on the frame strengthening topic. This won't be a 1/4 mile car , it will be mostly street driven, with the occasional roll on to see how the sport bikes react. I believe the 0 mph launch of a 1/4 mile run is much more stressful to the frame than a more gentle roll on. I've been looking at some single turbo project photos, and the exhaust still looks messy. When I did it last, I had no intercooler ( because they were very rare ) and the plumbing was therefor a bit more simple. How about using the space behind the front wheels ? Some Corvette twin kits place the turbos in those areas. Just an idea. I have a bunch of 4130 Chrome Moly tube laying around, I can use that for bracing and triangulating. As far as the Scarab that it is now, I do like the basic simplicity of it, but I did get the car as a base for a turbo project. I plan on selling the 1964 327 and 4 speed tranny after the new motor is ready. -Les

Slight correction: It was assembled from a Scarab parts set, back in the early 80's. Not an official Scarab car. Just got back from a drive, and the clutch master cyl. went out. Driving home with no clutch is not very fun... Back to my question: Turbo plumbing. Anyone have any thought on this project, single vs dual, and modding sheetmetal to maybe make room ? Thanks! -Les

Hello all, new member here ! I recently purchased a 73 with an old Scarab 327 conversion! My project begins! My first dilemma is: The car has the official 'bureau of automotive repair' engine swap sticker in the door jamb. The 327 is a 1964 block, matching the sticker data. Should I keep this engine ( rather than sell it ), in case good old California does some switcheroo of smog laws and starts asking for smog inspection on all cars ? I have an LT1 engine that I want to replace the 327 with. I will drive the 327 while I prep the LT1. I'm building the LT1 as a turbo motor. So I've looked at many of the pictures on Hybrids, and still can't tell for sure if it will be possible to do a twin turbo, or do I go single? The duals have integrated waste gates, and don't need a cross over pipe, and the T70 I have for a single would need an external gate, further complicating the plumbing. But the single could fit in the corner of the engine compartment, still allowing somewhere easy for the alternator to live Can I remove sheet metal from the inner fender near the strut tower to make more room? I worry that the tower top would become weak, and the weight of the car is taken by that point. I can TIG weld, so perhaps I can open up some space while adding some reinforcements. Any chance some of you twin turbo guys can chime in here, with respect to the exhaust plumbing ? Side note: Many years ago I swapped a 302 into a '74 Merc. Capri ( the old German one ) , and that was a single TO4 turbo. No intercooler back then, and it was a draw thru setup. It was a fun car. ( BTW , this site is a great resource for this ! ) -Les
