Just another 2jz FD Thread...
After going back and forth for a few months, I've finally decided to bite the bullet and swap my 94 RX7. I got the car last october after selling my 05 STi. It's a very very fun car but I just think swapping it will be a better way to make the kind of power I want!
On with the build...
I'm going to be using all tech2 swap parts, a stock usdm 2jz longblock, 74gts and tons of bolt ons.
I have about 75% of the parts at this point and I will soon be finishing up ordering everything!
Anyway, here are some pics to start the thread off!
I found my motor on Supraforums the sunday night before christmas at , 8AM the monday morning I was on the phone with the seller and at 12PM that same day I was on my way from baltimore to miami to pick her up.
A quick stop by titan to blow some money
My method of transportation
FYI, the amount of ghetto involved in the transportation of this motor does not mean this will be a hack job swap :p
Last but not least, the car!

Hehe
As long as he uses their cradle and hood(or hood with similar clearance) there will be no bumpsteer issue.

The sound of the hatch didn't bother me, but the sound of open header due to the fact that my exhaust was taking out the reflectors in between the lane dividers in the roads got to me, had to take it off in a walmart parking lot with a POS jack and mini wrench set they had.
Now that, truly sucked.

Estimated budget is going to be right around 15k, I will be doing all the work myself except the last IC pipe fab along with the exhaust fab.
My goals for this year are to get the car up and running, working all of the kinks out, I'm going to be running 100% stock longblock including stock cams, I know it works so I'm not touching it until the car is all sorted out, I'm also going to be running 1 denso FP for now, as dual pumps or a monster fuel setup is just more to sort out right now.
For this season on the r154, i'll be happy with the r154, I'll be happy with 575-600HP and a high 10 second pass. Next season, I'll be going 6spd, having the car caged, doing a monster fuel system and pushing the 74mm as far as I can, which should, note that I said SHOULD give me the numbers to make it into the high 9's. However having those numbers on paper and actually pulling it off of course, are 2 very different things.
I'd say my ultimate goal though, is to have a reliable (for what it is) 800-850HP car that is capable of a 9 second pass.

will your hood close with your kit? If not, what are you going to do? Buy a 1000 one from tech2? or have a shop pull it out?
I have my rb25 in my fd now with my new custom subframe that fits in the stock position, but I don't know what to do about hood....

I'm up in the air between the scoot hood and the tech2 hood, if it comes down to it, I don't have a problem buying tech2's hood.
I might buy a spare stocker and try to have it pulled to put off buying the tech2 for a while.

Is dropping the steering rack really that big of a problem? Cant you just extend the links to the knuckles and return the geometry pretty much to stock? Im talking about for a street car, not a circuit racer or anything.
How was your car Roachdiddy? I know your motor wasnt sticking out of your hood?

Its an extremely bad idea to mess with the steering geometry(lowering the subframe) I made this mistake when I made the first subframe for my car, I used aluminum stock to space the subframe down. You end up with way to much caster and some bumpsteer. I would rather pay a few more bucks for an aftermarket hood then not be able to control my car...

NO Bumpsteer = NO bumpsteer kit 
Here's what their site says:
The kit is designed to work for 2JZGTE and 1JZGTE motors with a R154 transmissions. This RX7 FD3S Swap Kit puts the motor as low and as far back as possible in the engine bay. You do not have to modify the chassis to install this motor swap into your car. All of the factory pick up points on the suspension remain intact as well as the steering rack location

you can use a kit or just buy extended tie rod ends, but that does not fix your problem all the way, that just helps bump-steer which is not even your biggest problem you still get caster to the point where it can't be adjusted depending on how much the tech2 kit brings down the subframe. Im not saying it can't be corrected but you will need to find someone who knows what they are doing and end up speeding as much as a tech 2 hood.

I have a hard time understanding how this will affect anything.

Either the steering rack gets lowered and you deal with bumpsteer, or you leave the rack where it's supposed to be and you get a Tech2 hood or one with similar clearance to compensate for th JZ motors' height. You can try setting the motor further back into the firewall as another member on this forum did, but that still seemed to require a bulge on the factory hood to gain some clearance.
