Tx2k8 Drag racing.... 1.5jz poll

[tissimo]

The rule is MK 1-3 1jz or 7m is a class. No rule yet on a 1.5jz.

A 1.5jz IS a 2jz motor with a 1jz head. IT IS NOT a stroked 1jz. A stroked 1 jz is a 1jz block with a longer stroke crank installed. In comparison, a SBC 400 with a 283 head on it is not a 283. It is a 400.

This is still a grey area in the rules. The drag rules are not set up for body type at all, and will never be. There are many classes just for mk4's, They are not piled into one class either. The rules are set to make a more level playing field.

And yes, if some one puts a 7m or a 1jz in a mk4, then it should run with the mk1-3 class.

I personally say a 1.5jz is a 2jz with a 1jz head. Call it a 1.5 all you want, the simple fact is that it is still a 2jz motor now. On the other hand i don't really care where they run because I will kill all of them with my 7m next year anyway.

If it were decided that 1.5jz ran with mkivs then someone build a stroker using the stock 1jz block making it a 3L 1jz would they have to run in the mkiv class as well? There is no real difference at all. The block is a bit taller, and thats it.. oh and the 2jz stamp on it.

And SBC are rated in Cubic inch, so it isn't a vailid argument cause 350 != 383, but it uses a 350 block..

There are no rules to gover the 1.5jz for tx2k8. So if someone did stroke a 1jz it would run anywhere the tech person will alow it. I would imagine with the mk3 super mod class.

A stroked 7m or 1jz block is still the original block. A 1.5jz is NOT a stroked 1jz. It is a 2jz motor with a 1jz head any way you want to look at it. I have not problem with a "real" stroked 1jz.

You missed my point with the sbc thing completly.

A cylinder head only does not make the motor. If it was possible, and I put a 7m head on a 2jz block, it is still a 2jz motor. Does not turn it into a 7.5m or something. And yes it should run in the mk4 2jz class.

Like I said. All the rules are set for tx2k8 already and this poll will change nothing. I personally don't care where the 1.5jz runs since I plan on killing all of them anyway.

Lance has the say on the mkiii rules per peter.. I figure this poll will help figure out where the community wants them to run and help lances decision on this..

Yea, I get what your saying about the head thing. I'm just saying theres nearly no difference between a stroked 1jz block and using a 2jz block. so if a stroked 1jz is allowed a 1.5jz should be allowed. If a 400 ci block is in a different class but a 350 stroked to 400 ci is allowed, just doesn't make sense..

obviously theres classes so you wont see a 3.4 2jz racing a stock 7m.. So dont bring up that argument. And if a guy who spends all his money on a 3.4 2jz and only wants to use a 67mm turbo, why not let him run a 7m with a 67mm turbo? they'll make the same power.

In an ideal world I'd like to see mkiii and mkiv racing...

Have the stock classes.
Stock MKIII (stock 7m, stock 1jz)
Stock MKIV (2jz twins) (of course 2jz mkiiis would run here due to the obvious power advantage over stock 7m/1js)

Then lump them all together with turbos limiting the classes..
Class 1 67mm or smaller
class 2 76 or smaller
class 3 76+

that way will have some fun racing..

If its not done that way, they should be done by body. a70 vs a70.. who cares what engine they have, limit the turbo size and run with it. Is a 600whp 2jz faster then a 600whp 7m.. No so why put them in another class, it makes no sence. Just that 7m/1j guys want a handy cap.

i like this the most. Based on mod, not on engine or chassis.

a 600whp Mk3 7m, has the same chances and 600whp Mk3 2jz or a 600whp Mk3 1jz...


like i have said before.. all you guys fighting to change the rules, better be out there running your cars!!!

its about torque sorry just wanted to keep adding fuel to the fire

just adding a 2JZ block to a 1JZ head does not make a majority of the motor 2JZ. thats the stupidest thing i have ever heard. theres alot more 1J stuff and parts on the top end of the engine than there is 2J stuff in a 2J block.

IMO a 2J block on a 1J head is a stroked 1JZ. no matter how you look at it. if you bored and stroked a 1J block then it'd be the same damn thing.

i still say it should go by classes of performance. not engine. and theoretically a stock 2J MKIII doesn't have a power advantage over a stock 1J MKIII because 99.9% of the 2J MKIII's are ARISTO motors which in turn make both motors 280hp.
