<\/a><\/p>\nWe modified a few things in the GTM kit. \u00a0For one we moved the placement of the BOVs. \u00a0They were located extremely close to the MAF sensors causing drivability and tuning issues. \u00a0We also removed the water injection system, improved fitment of a few pipes, and powdercoated the pipes black from their original polished look. \u00a0Silicone couplers were also all swapped out in favor of Vibrant brand couplers. \u00a0Fixes are pictures above. \u00a0Another thing you may or may not have noticed is this Z also sports an R35 GTR intake manifold made possible by GTM.<\/p>\n
The custom lower plenum that makes it possible to run a GTR intake manifold. \u00a0We removed it to weld up the holes (pictured) for the old water injection system. \u00a0No need to run water\\meth now that we converted this Z to ethanol.<\/p>\n GTM fuel rails feed Bosch 1000cc fuel injectors.<\/p>\n Feeding the rails and injectors is the CJ Motorsports twin pump fuel assembly. \u00a0Two Walbro fuel pumps feed the system. \u00a0We swapped one of the 255s with a 485.<\/p>\n One of our modified pipes finished in powdercoated black.<\/p>\n The finished product.<\/p>\n Onto the fruits of ours and John’s labor:<\/p>\n Peak boost of 15 psi, average of 14 psi we managed 567 whp. \u00a0This is for 91 octane. \u00a0After this we began working on the ethanol tuning.<\/p>\n 18 psi for 615 whp (ethanol fuel), we slowly worked our way up.<\/p>\n 19 psi for 674 whp.<\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n
