I am in the process of my 1JZ swap on my Z32, and the motor I purchased is a rear sump motor. If I go with the rear sump route, I'm going to have to set the motor back about 4.5-5 inches to clear the steering rack, meaning I have to modify the firewall. Z32's are front heavy to begin with, so I thought it would be cool to even out the weight ratio a bit. I will be able to keep my wipers and all of that as well. I will have to re-do my brake lines, which I already planned on redoing since I am deleting ABS. If I go front sump, I have to modify the crossmember, the car will be more front heavy, and there will be less room for the cooling setup. In doing the front sump setup, I will not have to modify the firewall.

So my main question is, are firewall modifications completely illegal? How do the BMI car and D-Macs Solstice pass tech, along with other cars I'm sure? And don't all of the guys running LSx motors in S-chassis have to modify the tranny tunnel/firewall?

I've heard firewall modification is illegal, so I'm looking for a solid answer on this. Thanks in advance!!

You can put a LSx into a 240 with out modifying the firewall/tranny tunnel. It depends on the install kit, or who makes the mounts.

Some might require you to hit some spots with a hammer.

Sell 1JZ, buy VH45.

Both problems solved.

also, a Z32 is not gonna be Formula D competitive, so it doesnt matter.
Do what you want.

Best of luck with the Z32, they've never really been the most competitive vehicle in any of the country's people have tried to compete with them!

Not to sure on your question, maybe call somebody from FormulaD?

I think it's a bit unfair to say that the Z32 is an uncompetitive car, since there have been successful big cars in FD like Soarers, Supras, etc. It's really about the driver and the car setup.

See i don't remember him asking opinions on his choice of chasis

Csomme

You cannot modify the firewall other than the tiny bit you can modify for the tranny tunnel.

Dmac's car still has an unmodified firewall. Always had, always will.

BURSTspeed

I have a z32 that I drift on a basically stock setup. Its fine, but the stock steering angle doesn't let you hold that much of an angle during a drift. Thats one thing that ticks me off lol. I definitely say go for the z32 since no1 else is doing it. Sorry this was not related to your question lol.

To the OP, Im in your build thread and when I saw that you wanted to cut the firewall ,I thought to myself dont do it. As for Formula D the mods you need to do will not pass!!!

I say front sump it just to get it done. But if your gonna cut it up then shoot for 50/50 or bust

To the other replies ,being competitive & wining are two different things, money and development can get you either .

What makes you guys a Z32 can't be competitive? They're an already upgraded S-chassis. I get just as much angle as an s-chassis with knuckle mods, and 2+0 Z's have the wheelbase. I have absolutely no problem drifting my car.


Cool, thanks for responding to my actual question, lol.

RPSil13

sell the rear sump to someone putting a jz into their supra/soarer and get a front sump,

supra/soarer people basicaly throw front sumps away, check supramania.com

Well, I got the 2011 rulebook, guess I'll have to scrap this idea.

8.4 MODIFICATIONS OF THE STOCK, OEM FIREWALL AND TRANSMISSION TUNNEL ARE ALLOWED AS FOLLOWS:

Dimension A= Tunnel Width May be no wider than 18 inches

Dimension B= Minimum dimension of 10 inches between the bottom of the
windshield and the top of the transmission tunnel.

Dimension C: Modifications to drive shaft tunnels behind the engine firewall
vertical plane should not exceed an overall width of 10.000 inches.

Dimension D: Modifications to drive shaft tunnels behind the engine firewall
vertical plane should not exceed an overall width of 10.000 inches.

Taper Length from the firewall to the end of the transmission tunnel into the
beginning of the drive shaft hump may be no longer than 36 inches.

No part of the engine casing may cross the vertical threshold of the original
firewall into the transmission tunnel.

No other modifications may be made to the vehicle chassis, frame, or
unibody.

Any holes in the firewall must be of the minimum size for the passage of
controls and wires, and must be completely sealed to prevent the passage of
fluids or flames from the engine compartment to the cockpit.

ericcastro

But they dont have the hinderance of steering angle issues and weight/balance that he's about to run into.

And I remember this being a forum.

"a public meeting or assembly for open discussion "

So you can gladly fuck off
or get used to it

Who cares what car it is, just go out and try. If you kill it, then you will be known as the guy who killed it in a z32, if you suck, then you can blame the car.

ericcastro

Anyone who builds a car to Formula D spec, and spend the money for it,(cage, fire system, seats, tech inspection), you want to make sure its gonna work ahead of time.

Thats who cares.

not your money or your car so why get so upset over someone doing something different?

TTnickdizzle

Thats really shitty, i bet it would have been nice to get some out the weight away from the front. But a bright side now the DP should be a lot easier to figure out now.

NismoTuner21

It works.

I've done 90mph entries, technical tracks/layouts, get lots of angle, and the car has never had trouble keeping up or doing anything other cars could do, and this has all been on stock LSD. I never said I'm building a full professional FD car... I'm just checking on shit like this that would be permanent in case this chassis and I ever do make it to that level.

GT Motion

Does your car have all wheel steering?

Future_gohan

That's a such a dumb answer and is completely off topic.

I wouldn't cut the firewall, that's why i sold my ls1 so I didn't have to cut my firewall, I do agree with you on the weight balance issue, but the 1jz isn't that heavy of a motor, so moving it forward a tad won't hurt you that bad, I mean they don't cut the firewall for the rb's and they are about the same size.

I bet if you ever think of making that move, you will rebuild an entire new shell, and just transfer everything over that you need, and get rid of the rest.

Its a lot easier then trying to keep slimming a car down to race spec.
Plus, you can FULLY stitch weld it, paint the frame, tube the front of the frame out, put the cage in, loose ALOT of unnesesary wiring and any other little issues that always bothered you

I wouldn't think so.
Especially with other people voicing the same opinion.
Or should I say warning.
I would hate for this guy to make an awesome car, spend a lot of time and money, and realize to late that its just not a good platform to be competitive in FD drifting.

Now ASB, ECB and all that, please do, it would be awesome.

BTW, you trying to argue with me is off topic.
Considering i have been drifting longer then you have been driving, i may know a couple things you dont

That's such a cool thing to know, thanks for letting me know.

Your comments were stupid because they're offtopic and were not needed. The z chassis is an amazing chassis in its self, and you shouldn't be talking down about it. I've driven and drifted plenty of 240's, and 300zx's. and I for one perfer a 300zx any day, but I don't have an opinion on that because you know, you've been doing it longer.

He never said it was a bad chassis, he just said it doesn't do well as a drifting platform. I mean an international bus is a good chassis for what its meant for, but it doesn't make a good drift chassis. I for one have been walked by several z32's on a road course, because they make decent platforms for that. The original opinion was given to try to save the OP some money, since in the original post it seems that he is building a FD spec car. Usually there is a reason that no one has had success with a chassis that has been around for years. It's a bit different when its something new that no one has had the time to perfect yet. But you're talking about a car that is at least 16 years old. I think by now if someone was going to compete on a major level with this chassis, it would have happened already.

What makes the FD Challenger any better than a z32?

holemilk00

So you're saying a challenger and a z32 are the same chassis with different body work?

I'm going to start with wheel base, then move on to a turbo inline six vs a v8 with torque, not to mention weight, and a host of other things. They are different cars man. That's what makes them different. That's like saying what makes a 240 different from a ZO6.

what makes a 240 with a lsx different than a zo6?

Same shit bro thats why people drift corvettes.
