Tx2k8 Drag racing.... 1.5jz poll

[tissimo]

Last year at Texas there was a bunch of confusion on the 1.5jzs, as 1jzs were allowed to complete in hte mkiii classes but 2jz were required to complete with the mkivs. Ended up the 1.5jz cars ran in the mkiii classes last year, but there was a bunch of confusion over it. So to solve that, I've decided to see what the community thinks about it.

Should 1.5jz mkiiis compete in the mkiii classes or the mkiv classes?

1.5jz is a 1jz head and 2jz block? if so then its a 2jz.

yes a 3.0L 1jz using a 2jz block

Why not make it simple and base it on body.

:word8kn:

I think it should be listed with the body styles, no matter which motor you have.

It was previously decided that the 2jz has an unfair advantage and should be racing with the mkivs, so 2jz swapped mkiiis are racing with the mkiv. But The grey area is 1.5jzs.. Last year they competed with the mkiiis, but people complained.. so Hence the poll..

Then you could be out classed easily. Thats no fun!

 

[Mr.PFloyd]

The 1.5 jz is a 2jz. Just the same when you stroke a 3s with a 5s Block. they aren't called 3.5SGTE's, but instead they are called 5SGTE's. So they become part of the 5S class.

 

[Sawbladz]

I think they should be with the MkIII's and so should the 2J guys. They all have the unfortunate disadvantage of pushing nearly 4000 lbs down the strip so why are they racing Mk4's?

People who have done the 2J swap have spent enough money that they could easily have a really fast 7M, but they made a personal choice not to. This is kinda like someone with only an upgraded CT complaining it's not fair that people can run big singles. Or that people can run automatics with stalls.

my vote is that it should be classed as body style.

and a 1.5JZ is NOT a 2J its a stroked 1J. just like a 3.4L stroker 2JZ is still called a 2JZ!!!

and i dont think it should be based on motors. it should be based on the chassis. all these people saying the 7M is a badass motor and rep the 7M strongly should step up and beat the 2JZ MKIII's. If you think the 7M is so high and mighty then it should be just as evenly matched as a 2J mkiii. same weight and they both can make gobs of power so whats all the bitching for??

i vote for classed by Chassis NOT engine.

Having 2Js in the MKIV class but 1.5Js in the MK3 class is rather lame.

Would a 1J MKIV be competing in the MK3 class by that same classification?

where do 1J/2J/7M swapped MK2s go? The MK3 or MK4 class?

Do the 3.4L Supras get their own class?

Base it on body and leave it there. That's the best answer. Otherwise, the line separating various cars seems to be very unclear.

But the stroker 2JZ uses a 2JZ block, The stroker 1.5JZ... uses a 2JZ block The majority of the engine is now a 2J, with the same displacement as one, so why shouldn't it be classified with them?

This is just like when Honda guys put the K24 block under their RSX head.

I agree with body styles. Let the owner put whatever they want under their hood, it just keeps everyone else building their platforms stronger, whichever engine it may be.

So... If i were to slap a 3.4 stroker 2j under my 1j head, then I could run it in the 1.5jz MKIII class?

 

[MassSupra89]

That's actually something I was thinking about a few weeks ago... Have to hide a GT47 in there somewhere too to get the ultimate sleeper approach.

 

[tissimo]

IMO, yes.. But need a turbo limit like the mkiv classes. sort of limits the hp in the class..

 

[suprarich]

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.

The day that all I care about is how good my Supra will be on a racetrack WILL be the day I get rid of it. For almost every car that attends TX2K8, the driver is gonna go home with a fat lip. I want my car to be fast, comfortable, good Looking, and economical (to a degree). IF I am able to come, and IF I race, I will find something else to shoot for other than being the fastest. You know, like maybe my 7M beat your 1JZ or 1.5JZ......or for a personal best. It doesn't matter if I win every race I get in or not.

I say body style! Let the 1.5's run with the MKIII's.

This is an interesting topic ...I think it needs to be done by motor platform ... I think its more about $$$ invested in the given platform ... how do you build a class based on that though...its tough ... I wouldn't mind racing 1j's or 2j's but someone else with far less invested in there given platform probably wouldn't appreciate being placed in a class where the average $ amount spent on a motor is more than the entire car..

True, but the breakdown on how much something costs depends if the person bought their performance or built their performance. There are those MKIV people that will blow 10k on a greddy t78 kit with the greddy 3 row IC and have it installed, or there is the guy with the ebay manifold, the garret t67 and an ebay 24x12x3 IC that put their parts in in their garage. Are these parts relatively the same, yes. However the money spent on the ebay/t67 is 1/2 of what the greddy system would be.

IMO it should be done within power ranges (measured in bhp, not whp). 500bhp is 500bhp, doesn't matter if you are on an upgraded 57 trim with a small shot of nitrous, or a MKIV on stock twins.

All class rules are already set. All the poster was asking was about a 1.5jz classification. Last year all the "2jzs with a 1jz head" cars ran with the mk 1-3 7m-1jz super mod class.
