I know u r going for #2 spot,this is a new rule just in case u didnt read it, 2JZ are not aloud to be in the list anymore,Sorry but u have to downgrade to 1JZ![]()

jaja i got a 1.5jz not a 2jz
but i heard those engines dont make to much power 1.5JZ

You can also call out Fernandito white SRT4 to make it on the list...

is his car ready?

It should be noted that the 2JZ-GE (Naturally Aspirated) bottom end has no oil spray bars as found in the 2JZ-GTE (Twin Turbo) bottom end. Galleries and mounting bosses do exist in the GE block to allow the addition of oil spray bars, however this requires machining.
1JZ = 2.5L Inline 6 (86.0mm bore x 71.5mm stroke)
2JZ = 3.0L Inline 6 (86.0mm bore x 86.0mm stroke)
Using a 2JZ bottom end with the 1JZ components allows an extra 500cc of displacement.
Reasons for this conversion is a matter of opinion and discussion. The 1jz has a larger Exhaust valve at 30.0mm yet a smaller intake valve of only 31.0mm whilst the 2JZ has a 33.6mm Intake valve and a 29.0mm exhaust valve. The debate is, that it was easier to go 1.5JZ instead of 2JZ due to electronics, and configurations for pre existing manifolds etc.

What is known is that the 2JZ head compared to the 1JZ head has more restriction in the 5th and 6th cylinder exhaust ports due to an S shaped casting. The 1JZ also has different shaped combustion chambers which, when directly placed on a 2JZ block, increases the compression slightly and leads to a power increase when using unworked heads. Once worked (ported and chambers reshaped, valves resized) the heads have been proven to flow much the same.
The most likely reason for the setup would be if the owner of a worked 1JZ engine suffered from bottom end failure or if they wanted the extra displacement and torque of the 2JZ bottom end, as the heads are interchangeable. Thus all the existing manifold, plumbing, fittings, turbo(s) could be retained making for a very cost effective power and torque upgrade.
This is what is going to happen to peoples car when they try to race the The CrusherCobra when it comes out...Sooo Sandor Are you ready for this??
