2JZ | 3.4L Stroker | Pump Gas Dyno Tune

[top dead center]

Austin’s 2JZ-GTE swapped G35 sedan has been a shop project of ours for a while. We’ve had the car running for some time now, but during the last dyno session, a thrust washer failed in the stock JDM long block , causing the bottom end to seize. Austin had us rebuild the engine, this time as a 3.4L stroker engine. We also installed several other parts, to support his long term power goals. Right now, the car is limited by the R154 transmission, so we’ve only tuned on pump gas. When Austin switches the transmission to a V160 6 Speed, we’ll be tuning on E85 and turning up the boost.





Here is the setup:

Titan Motorsports 3.4L Crankshaft
Carrillo Rods
JE Pistons, 9.2:1, 1 mm over
ACL Coated and Main bearings
ARP Main Studs

Stock Port Head
Supertech Springs and Retainers
Stock Valves
Kelford Cams
ARP Head Studs
Toyota Head Gasket
God Speed Intake Manifold
Edlebrock Throttle Body

Aeromotive A1000 Fuel Pump
RC 1200cc Injectors
Aeromotive FPR

Comp Turbo CT4 6765 Billet BB
HKS Style Manifold
Tial MVR Wastegate
3″ Down Pipe



Here are the results. This chart is on 93 octane. Boost pressure is at 21 PSI. Temperature in the shop was 97 degrees, with 47% humidity.

Wow 10+K longblock. That thing better fly...

And crankwalking a 2JZ? Man you guys must have been pushing that stock block!

No one can push a 2JZ hard enough to crankwalk, otherwise the engine was simply not built appropriately. However, it's an old motor. You have engines that could have been standing still for the last 10-15 years with broke down oil in the bearings. Usually, if something goes wrong on a used motor of this age, it's a main or rod bearing and it would happen within the first 100 miles from lack of lubrication due to the caulking of the old oil preventing the new oil from making contact.. In this case, a thrust washer failed as a result which is very uncommon. If I buy a motor that old, you can bet that at the very least, the bearings will be replaced. Maybe I'm just a little too precautions. Truth be known, the majority of these imported motors turn out fine but occasionally, you'll run into something like this.

what's up with the top end? what size turbine housing is on that thing?
