BP’s ’04 RSX is quite the sleeper.  Under the hood lies the 2.5L ERL K24 “Budget Stroker” bottom end with stock k20a2 head and z1 cams.  Additional components include the ASP Header, ASP 3″ Aluminum exhaust, RDX 440cc injectors, and dyno tuning via K-Pro.  The z1 cams and valve-train are the limiting factors on this set-up.  This engine was built for a 300whp+ NA set-up and will soon see either the Drag Cartel Stage 4 or Stage 5 cams with larger injectors.  We hope to see around 315-330whp on this naturally aspirated set-up with the addition of the cams. 

Overall, the preliminary numbers of 245whp/201tq are not to shabby considering we had dyno temperatures of 101 deg and IAT’s of 120 deg with 38% humidity.  On an ‘ideal day’, we expect to see another 10-14whp in ideal weather conditions.

Compared below is the K24 Budget stroker (Run_021) to a stock K20a (Run_006) with CAI, full 2.5″ exhaust, and Hytech Race Header.  For the peak power number guys out there, we redyno’d this K20a at a later date in ‘ideal’ conditions and we made roughly 232whp.  The conditions from the 2 runs are essentially identical (temperature, barometric pressure, humidity, etc).  With more time, I feel that the K24 could have picked up another 10-15whp to make around 260whp and show even more impressive midrange gains.

Phase 1 of KR’s Track MR2 has been completed.  Upgrades include a Full-Race t3 Manifold, 3″ Downpipe, Tial 38mm wastegate, Precision SC44 (T3), Greddy Type S BOV, TurboXS BC, Alcohol Injection, and universal side-mount intercooler.  Against our recommendations, this application was tuned only using methanol injection.  Phase 2 will include the AEM EMS and full 3″ Exhaust which will allow us to make much more power (roughly 300whp) with the ability to fine tune every parameter as well as safely run increased boost pressures.  To help combat against heat-soak, we redesigned and fabricated a custom aluminum intercooler piping kit as well as designed a heat-shield system which lowered IAT’s by 40 degree’s. This car currently produces 234whp/203tq at 11-12psi.

Run25: 234whp/203tq 11-12psi      Run 27: 186whp/185tq 6psi

JK’s sleeper 350z features the APS twin turbo kit running roughly 8psi.  This kit runs twin Garrett GT2871R units, the APS 2.5″ Exhaust system, and the custom mapped APS tune.  Looking for more power in the near future, we hope to see around 500whp with the upgrade to a 3″ exhaust, a fully programmable EMS, increased boost pressure, and of course lots of time tuning it to perfection.

Another simple but efficient set-up completed.  Some of the components this set-up utilizes are the Neukin log manifold, Garrett T3/t04e turbocharger, tial 38mm wastegate, RC 440cc injectors, Walbro 255 fuel pump, 2.5″ DP/Exhaust, custom IC piping, and Hondata s300.  At 8psi we managed to make 250whp/172tq.

We are staying busy as usual with some very nice set-ups in progress.  Below you will see a few pictures of ES’s GT40 Turbo S2k and WB’s 450whp EG.  WB’s EG has been a very long project and was originally a white chassis with complete blue interior.  With the addition of the Integra DC2 dash/carpet, Bride Carbon Kevlar Seats, and all new black interior components this car is essentially flawless.  The remainder of the interior components are being reupholstered to match the front bride seats.  Keep checking back for further updates on this project.
