Full-Race Turbo R18 Honda Civic EX - powered by BorgWarner EFR 6255 turbo

Doug from Hondata building the Full-Race turbo R18 basemap. Phase 1 of the dyno tuning was done as shown in the video using a 100% stock R18 engine, and Full-Race R18 turbokit + Full-Race FA2/FG2 3" exhaust.

Extra supporting mods are: RDX injectors + walbro 255 fuel pump + 6puck clutch + Hondata Flashpro. For phase 1 we decided to use the smallest EFR turbo in the family, to represent the fastest spooling, but lowest power output possible with our kit.

Phase 2 will be done with the hondata 4bar map sensor (so we can turn the boost above 10psi) and a larger EFR turbo, the 6758.

What is the boost pressure achieved in this stage 1 set up? If the boost controller is disconnected, is the boost pressure regulated directly by the diaphragm?

255whp is good, what's the baseline of this engine in stock form?

[FullRaceVids]

@cplim72 boost pressure is 9psi, rising to 10psi for a minute, then back to 9psi. Regulated by the diaphragm with 2mm of preload on the wastegate canister. Boost would be 7-8psi with 0.5-1mm preload (you always want a tiny bit of preload). fuel used is poor grade arizona 91 octane pump gas. this engine stock produces 113whp

[FullRaceVids]

only doing low boost testing - boost controller disconnected. also the smallest EFR turbo in the family... 255whp to start

CRAZY! Can't believe you guys are pulling that much power out of this lil motor with such minimal mods.

Question -> how difficult would it be for the garage mechanic to mod this motor, since it's in such a confined engine bay? Seems like you'd have to pull the motor to install the injectors!?

[purvertedmunk]

what would be the best setup for time attack events?

[Athens2k4]

do you proceed into the phase 2 with a larger turbo on r18 ?

[nmarkus666]

@XxRuffRydaxX vtec doesnt like boost? go watch some videos with real honda motors the R18 is garbage. K-series ftw.

[XxRuffRydaxX]

@markb16a the standard wastegate is at 42mm. For internal it's huge and you would be a fool to change to external just for the sound alone. It's always interesting to see turbos on V-Tec setups but I personally believe the V-Tec is more suited for a supercharger than a turbocharger. V-Tec doesn't like too much boost and a supercharger would have more power to play trhought the entire band, although the EFR is very responsive.

@FullRaceVids what do you think of using hondata? good for $700 price?

[DeepFriedPotato]

any chance of this working on fd1's?

[silversn4ke]

oh my dear lord... this EFR really is the business... i could hear it spooling from IDLE! ive got to get my hands on one.

[complexr]

more efr dynos and graphs please! big power upgrade for stock motor!

[whity98]

Friggin AWESOME! BW ftw doesn't matter what car its in.

[nycclaye]

and it's bc of this, that my 07 Si has an FR Mani and a GT3076 now lol. I'll be damned if an ex can catch me lol.

[markb16a]

is this internally wastegated? didnt hear the good stuff?

[Athens2k4]

How mutch power ? does it pass the 200whp with this setup ?

[link199z]

OOOOOh, so long I have waited for this!!!
