Need help with EJ207 setup / Massive turbo Lag
Hi All,
yesterday i took my wrx to the dyno to tune and test it , but seems like there is something wrong with it and I cant seem to find it , I need help please 2004 subaru wrx with ej207 and 6 speed swap the problem is that the car is not making enough HP for the setup (below) dual maps tune .. low boost is 0.8 bar and high boost is 1.2 bar (high boost will be around 1.5 bar after fixing the issue) Its making only 330whp and 400tq on 1.2 bar (93 octane) , noting that it made 390whp and 500 tq on almost the same setup but with a TD05-20G turbo . the garret that i have now is much larger and it couldn't even go near the TD05 numbers . any ideas ? there is no boost leaks and every thing was checked at the dyno , AFR is optimal and the car is running great . the tuner is great and he tunes almost all the high hp cars in town . **note : the boost kicks in around 4500 RPM and its super lagy , full boost is around 7200 RPM Engine CP pistons Manley connecting rods Brian crower crankshaft (2.2) OEM headgaskets (low compression) (needed because the pistons are low compression ) Brian Crower Valve Spring & Titanium Retainer Set ARP 11mm headstuds Closed Deck block ID 1000cc injectors KING XP series Engine bearings KING XP series Rod bearings NGK 1 step colder spark plugs walbrow 450lph fuel pump sytec fuel regulater ATP garrett gtx3076r (1st gen) Tial 38mm wastgate Borla full 3 inch exhaust system Link ECU (plug and play) excedy Single plate clutch 6 speed STI transmission

If that is a stock location gtx3076r it is really about the same size as a 20g because of the shrunken housings. On a 2l it would be even worse. show your dyno graphs from 20g and 3076
Are you sure its a GTX3076 and not the GT3076? |
