Time for a leakdown test I guess

My trans tunnel has become very hot since I went single turbo on my 1jz. The R154 is on 3L of MT90 and the shifter is quite hot to the touch (steel part)

Miss the 3k massive torque but I certainly don't miss the 5.5k powerband limit of the 7m and BHG/Rodknock shizzles beside, 4k hit really strong with my 6262 1jz, it's not THAT gutless down low

I altered my base map a bit I'm running 91octane on my 1jzgte Main mods: Driftmotion 6262 turbo kit Sard800 injectors stock cams 320lph aem fuel pump and here is my spark map: I'm running 18psi highboost and 15psi low boost. Boost cut is properly engaging @ 20psi and rev limiter...

There is only one R154 but on the soarer the extension housing is different (swap it for the mk3) and the DRIVER SPEEDO GEAR is a 10Teeth (IIRC).

I hesitated to start a thread but I just need a quick answer: I bought a JDM SOARER R154 to replace my destroyed Supra R154 (1 year ago). Obviously my speedometer is off, it reads a lot lower than my actual speed (I'm going 120kph, it will read 107-8 kph). I was wondering if I could just replace...

Bearing and mounting procedure was exactly the same as OP. I even had the DS balanced. I'm thinking about putting the stock bearing back on the DS but using 3M window sealer to give strengh back to the ol' rubber housing.

The ford ranger bearing lasted about 4 months before developping a massive whine of death.

if the tach needle jump from 0 to 7k, I'd check the ignitor circuits...

pushers are a lot less efficient because they create turbulance through the radiator fins instead of behind the radiator (like a puller). That being said, Zirgo make 3000-3300 and 3600cfm electric fans (I run the 3300cfm in a pulling setup and it is very efficient, coolant never go above 93C at...

A used R154 extension housing with the "bushing" In good shape. Stock Driveshaft (my 1 piece is toast'd) with new carrier bearing. new outputshaft seal and outputshaft bearing. it has been fine since that moment

Anybody running this kit have power figures? I'm running a 1jz, stock cams, ms3pro, 800cc sard, 3.5" catback, 320lph aem fuel pump, 2.75" in/out IC, 2.5" cold/hot side and this DM 6262 turbo kit. I have turned the boost up (18psi) and I am disapointed with the performance. The car is tuned...

Yes but what. Can you throw a hint or something. This is driving me insane

Bad news, the bushing that is pressed in the extension housing failed again, with another DS, leading to oil seals leaking. There is play now when I move the yoke (1-2mm). Should I source another extension housing ($$) or order a omega R150 tailshaft bushing...

I had to replace the rear housing of the R154 because the "bushing" part of it was fucked. Along with a new seal and a new DS

Go with a proper standalone and be done with it
