2jz Subframe

Im wondering how much interest there is in a 2jz subframe. It would be professionally made by a chassis shop, and use chromemoly material. Im just trying to get an idea of how much interest there is in sucha product. id appreciate email GTpoweredCORRADO@aol.com or a reply. Thanks
Greg

Probably not much since it is a major PITA to even get a 2JZ for a decent price.

It would be a cool conversion..... bye bye handling.

I have seen JDM 2JZ front clips going for over a grand cheaper than Honda K20a's. And those swaps are becoming faily common in the Honda camp.

The first would def. be for a 3rd gen bc thats what i have and thats what its getting built for. As far as the price I am not even sure yet. i am just trying to see how much interest there is. Ill still do it for my car but im just wondering if i should make a few other subframes to sell.

I doubt there'll be much interest. The LS1 seems to be the flavor of choice for the FD. And now that turbocharging the LS1 is becoming more common place I can't imagine people opting for the larger, heavier, more difficult to package 2JZ.

Good luck though. Let us know how you get around the bump steer.

bump steer? i don't think the SP engineering supra 7 had that problem.

btw LETHAL, i'm interested in this custom fab., but not right now. i'm also a fan of swapping in a 2j in the FD and will definitely do it in the future

fill me in Mdessouki. from what I'VE heard, it doesn't have have it as much as a lot of people think. of course, credibility from such resources can also be false.

i really wanna know since this is the future swap i'm going to forgo, and i wanna know the pros and cons about it

Forget a smilie? It has such severe bump steer that they can't do anything more than show it off at shows...They also can't seem to fit a hood on it since the 2JZ is so damn tall.

I've never seen anything "official", but here'e the link I was thinking of. That's one FUGLY hood BTW

https://www.rx7club.com/showpost.php...&postcount=231

Of course, another guy in the same thread says he managed to get his subframe/engine combo to work without having to drop the steering rack (though I have no idea how, since the motor is much taller than my LS1, which required lowering the rack to gain hood clearance).

Not to mention longer.

From SP Engineering themselves. It was in one of the magazine articles. They said they got a couple partial passes in, but that the car was all over the place and wouldn't track a straight line.

thanks jim, mike, and wingsfan for the headsup.

i guess doing the supra swap is out of the question now

i really wanted to do it badly too.. but seems like cons outweigh the pros..

btw, i can't wait to see if "mikey" can actually pull off the swap and get the car running and steering correctly. he might be right about his swap not having the bump steer since he himself is doing it. but we'll see

i have done it:

-no bumpsteer
-hood shuts just fine
-sp has a problem because of power (i don't think bumpsteer)...but they say the car will be out by next season for drag...this came from www.supraforums.com
-sp hood does not shut because of the HUGE turbos not the size of the engine

my car is on the road driving just fine. the only thing i am working on is the turbos. since my latest intercooler install, making piping for the stock turbos is a pain since i want it to look it's best.

keep in mind that getting the engine to fit in the car was the easy part of this project. messing with the rest of the stuff to make the swap work was the pain.

i plan to have wiring diagrams, detailed pictures, and anything else needed to pull this swap off on my website as soon as i get some time. Right now i just finished college and am looking for work. as soon as my life gets settled down, i will get all of this finished...i might even have the car up for sale if anybody is really interested.

With what modification? I seem to remember you mentioning that you had to cut out some of the supports on the underside of the hood.

Then why did they need a scoop in the center of the hood to a flare over the front turbo? (I won't even go into adding the extra "nostril"...)

the extra nostril i bet is for the veilside intake manifold. i honestly do not know why they have the scoop. if you look at where the engine comes up (vertically) to the firewall, it is the same place where my engine comes up to my firewall. my hood shuts fine with clearance and because of that i say they do not need that scoop. i do not know for sure...but it really doesn't matter. the hood will shut without relocating the steering rack.

You're saying that the steering rack doesn't move at all? The 2JZ is a tall engine, and obviously longer than a V8, so that's a bold statement...

Are you using tie rod end spacers to correct your steering geometry, or did you literally not move your steering rack at all? What did you have to do to the oil pan to accomplish that? Anything?

yes...literally the steering rack was not moved at all. i did not have to modify the 2jz's oil pan. really, you just have to weld in plates for the engine mounts. the oil pan will hit the rear of the rx-7's subframe, so you just have to make the rear part of the subframe not as think.

no pictures of my car yet...i will get some up as soon as i am happy with the looks of it.
