Just had my car re-tuned at EFI performance today after putting heavy duty actuator on:

Power FC

Apexi AX53B70 p25 turbo

Stock air box

Walbro fuel pump

Tomei adjustable fuel reg

Vulture motorsports plenum

Front mount IC

Apexi 3.5 inch exhaust

[old mate]

run in tune at 101,

greedy plenum, buit bottom, fmic, 3" exhoust, 4"metal intake, 3082r .63, hks cast adaptor and 40mm gate.

made 270hp on 7psi.

[C BOMB]

the ol neo.

HKS 2835 kai

nismo 480cc injectors

nistune

+ the usual stuff

tuned at 14psi. exhaust is causing a restriction

retuned with a new zaust.

320hp @ ~16psi

disappointed with the figure, feels significantly better however.

hopefully 89cal will have some good news for me soon.

Here's Mine:

Sorry, here it is..

186.7rwKW

545Nm

Stock turbo, 12psi

Disappointing power figure but very different and nice feel on street, very happy with physical result, but power drops off after 5000-5500rpms - as seen by the chart, can feel it on the street just as the chart indicates, lack of turbo ooomph after 5500rpms, that power result on chart was achieved at 14psi though, quite a disappointing number - was told my stock dump could be the cause. But then again it feels way faster and better to drive than the numbers indicate - fuel economy hasnt improved much though 15+L/100kms - but I do a lot of short distance stop-start driving and quite a few redlining as well..

R33 GTS-T S1

213rwKW @13 psi

13.1 @ 109mph

Highflow Turbo ( Unknown )

740 cc injectors

Malpassi Fuel Reg

Bosch 044 Fuel pump

Surge pump

3 " Exhaust

High performance Cat

Z32 AFM

Apexi pFC

HDI Boost Controller

Yellow jacket Coil packs

Intercooler

I think i should be getting a better Dyno result with the supporting mods... Anyone think differently ?

[SargeRX8]

Got my car tuned but its going back soon.

Anyway its an R33 GTST Series 2 with the following:

Unopened RB25DET

HyperGear ATR43SS-2

3" JJR Bellmouth dump

HKS Hi Power Silent exhaust

Yellow jacket coils

NGK Copper plugs BCP7RES gapped to .7

Genuine HDI FMIC

Venom 5" body 100cpsi cat

Nismo 740cc injectors

Bosch 040(was failing during tune)

Nismo FPR

Greddy profec b spec 2

3" metal intake with Apexi power intake filter

Power FC tuned by Advan performance

Made 244rwkw on 11.4psi. That is with the boost controller set to 100%. That is as much as we can get out of it. With about 15psi, we should see about 270rwkw and 17psi about 280rwkw. 20psi should see 300rwkw on regular fuel pump.

Ive fitted a GTR fuel pump in there to fix the fuel pump issues. Probably will swap that with a brand new 040 pump or run it as a lift into a surge tank. Last printed dyno shows about 238rwkw on 11psi, should have printed the previous runs

Here's update with the SS1 PU prototype.

291rwkws@21psi (run was not complete as cooler pipe slipped) when the cooler is cold and average of 270rwkws@21psi when the cooler is hot, 260rwkws@14psi.

Runs were done on 14psi (red) and 24psi (yellow/Blue) high pressure actuators. No boost controller was used on those runs. This turbo was not equipped with a gate controller.

9 sec ramp:

[Reflector]

1996 R33 S2 GTS-T M-SPEC II

Stock internals (except for 256 in/ex poncams and adjustable exhaust gear)

Stock Turbo/wastegate/manifold

3" Turbo back exhaust with a 3" into 5"body out 3" 100CPSI vemon cat.

Apexi POD Filter

Tomei FPR (large)

Intercooler

Spitfire Coilovers

NGK platinum tipped spark plugs gapped at 0.7t

Apexi AVC-Type R

GFB Aftermarket BOV (to confirm for anyone, NO boost leaks have EVER occured whilst using this aftermarket BOV)

208rwkw on low Boost - 7psi

214.7 on high Boost - 14psi

That was the most we could squeeze out as the actuator was being restricted and the air mass meter had reached it's limits. Upgrades to come in near future .
