Sorry guys, I still prefer the suck through carby setup, you don't have to worry about sealing the carby, accelerator cable and hoses for the fuel supply and so on,,,,a weber or su or stromburg or something that can flow enough air (cfm) to match the engine.
just use the standard mechanical fuel pump which should handle it real well. Power with a t25 garrett should be around 180 Hp at the fly wheel on conservative boost say 8-12 pounds. you can wound it out to 15 pounds but then water and/or methanol injection would be needed to keep detonation down. You really need heavy duty valve springs as this will enable you to rev a little more.
This injection can be made so it only comes on when you hit say 10 pounds. Throttle response should be really good and you don't need a Blow off valve as there is no throttle body in the way. So simple effective and practical, and it looks real cool seeing the carbys hanging off the turbo inlet. Better than looking at a box.
Its also so much easier to work on. Oh and don't use the T2 as the pulsars and exa's usually get a t25 which is better. Besides the T2 would be generating heat at the top end of the efficiency range, which is bad it encourages detonation. And summer is coming....so its gonna be hot.
