JF has always been an all-motor guy until a recent drive in a turbo civic.  After a few minutes in a turbo-charged car he decided to scrap his NA plans and go with a Turbo H22a set-up.  This simple yet efficient set-up uses a stock h22a4 engine, Peak-Boost turbo kit (t3 57 trim Garrett), Bosch 650cc injectors, Hondata s100b, Walbro 255 fuel pump, Koyo Radiator, Spal 1710CFM Slim-Fan and puts out 281whp/220tq at 8psi.  Unfortunately the manifold has minor boost fluctuations which is shown on the semi-peaky looking dyno chart.  In the near future we will fabricate a custom AV Engineering top-mount turbo-kit on this set-up while retaining AC.  We are looking at picking up a little bit more power with our custom designed manifold as well as allowing our customer to stay nice and cool in the during the hot summer months.

A simple set-up using Wiseco 9.0:1 Pistons, Eagle Rods, and 300 series Darton sleeves.  Unfortunately the log manifold caused a tremendous amount of turbulence after 14psi (a t4 70trim turbo was used) and would cause the boost pressure to fluctuate by 2psi when attempting to run an excess of 16psi.  Due to this we left the boost at 14psi to keep the motor safe.

Low Boost – 11psi 353whp/255tq

Medium Boost – 14psi 389whp/285tq

High Boost – 16psi 404whp/303tq
