There is no point using a twin scroll turbo on a standard manifold as it would be laggy as hell. If ur on a small budget do what Scotty said snd contact hypergear on this forum, he will help u out with something to suit ur needs!
N13 Nissan pulsar with a CA18DET, I used to have one had 350hp atw & ran 12.2@124mph wheel spin 1st second third. Would bag the tyres at 100kph on the highway. I miss it
Here is a vid of it at willow bank when it was putting down about 220hp
On the highway at 110kph my car is doing 2500rpm that just seems too low for 4:1's. also when I went down the quarter mile a couple of months ago it ran a 13.2 @ 101mph crossing the line at 7500 in third gear.. Maybe the gearing has been changed by the previous jap owner!
