Engine Dyno Tests 6G72~2JZ-GTE
Hello Community. These dyno tests were taken from a live engine dyno using brand new and broken in(50hours) 6G72 and 2JZ-GTE engines. I tried to make the test as consistent as possible with both engines using the same aftermarket parts. The T76 Turbos were swapped and used by both engines to measure any inconsistencies. This was a long test that has been going on for nearly 5 months. I spent over 400hours trying different scenarios, too much to write down, suffice it to say I tried being as accurate as possible. Stock rods were used on both cars. Here are the results.
Stock 2JZ-GTE= 331hp@5633rpm's
Stock 6G72 4b= 314hp@6028rpm's
T76 2JZ-GTE= 387hp@6292rpm's@10.0psi's
T76 6G72 4b= 384hp@6708rpm's@10.0psi's
T76 2JZ-GTE= 571hp@6424rpm's@15.1psi's
T76 6G72 4b= 593hp@6722rpm's@15.0psi's
T76 2JZ-GTE= 682hp@6610rpm's@20psi's
T76 6G72 4b= 714hp@6784rpm's@20psi's
T76 2JZ-GTE= 766hp@6641rpm's@25psi's
T76 6G72 4b= 809hp@6812rpm's@25psi's
Note: More than 2 dyno tests of each pressure was taken and these were the highest HP numbers recorded. Suffice it to say that most of the time the numbers were only different by a maximum of 1-1.5hp. VP Race Gas was used in all tests.
Stock Heads, Blitz 850cc injectors(full sets swapped 4 times between cars), stock valves, stock pistons. Consistent A/F throughout range, same for both cars, no detonation found on 116.
I used a K&N on both engines connected directly to the turbos. I used a custom HKS Titanium 3" exhaust on the 6G72 and the HKS Titanium 4" exhaust for the 2JZ-GTE. Custom 1.75" headers were used for the 6g72 and an RPS Header was used for the 2JZ-GTE.
**Note: no auxiliaries were used, air conditioning, power steering, etc... so HP figures will be lower with these in place**
Joe, I used an SDS EFI to control the injectors. The 2JZ used a Greddy 4 row and the 6G72 used a Custom FMIC. The large fan was blowing directly on the intercooler for testing. Stock Radiators. The temperature was 15degrees C in the room and we inputed this information as well as humidity into the dynomometer. HP Numbers are in SAE.

So oem vs oem the supra wins. But once the psi goes up...i wonder what makes more power?
Try again noob. Oh btw...the 3s has 33 degrees of overlap stock.
I know the 2jz can hold a shit ton of power, but no-one in the 3s community until lately has used anything BUT td04 turbo's. Just this year td05's became popular and people began to discover turbo's by this mystery company called "garrett".
Here is the thread.
