They are 14 year old Rajays' date=' 370 E 80's, that I'm borrowing from a friend.
[b']I'm using twins because I like the way they balance the look of the engine department.[/b] But if I had to buy the turbos, I would have used a large single to save money and to allow a much easier installation. Then a front mount intercooler could also have been mounted.
You would not like the looks of my exhaust system. In order to avoid carving up the inner fender sheetmetal, the dual 3" exhaust runs below the front crossmember after the down-pipes. Then the exhaust runs over the rear differential, through large Flowmaster mufflers and out the back. The exhaust is oval pipe which gives some clearance but I always scrape over speed bumps. Driveways and dips in the road are not generally a problem. Even if you buy used parts, turbos,wastegates, blowoff valves, downpipes, timing retard devices, big fuel pumps and fuel regulators will all add up.
Before adding the turbos the Z ran 11.15 @ 123 mph, regularly. Keep that in mind while saving money for the turbo system.
