The head will be full race port and polish with the valve tran work up.MY GOAL IS 500-600 WHP on daily driven dc2 teg,Now my question mainly is what is the best turbo for 600 hp that spools up at a decent rpm.I here alot about the sc61 but i am not sure on there spool and out put.Also what injector size would be correct for 600 hp.My other main thing i need to know about is what is the best turbo manifold to get to 600+ hp and have a/c.I have everything but the turbo ,manifold and DP.any help with this will get rep points.Please only respond if you know what you are talking about.Thanks alot for this info GUYS !!!.
