An rb motor is in the future of my FD... i am so pleased with my sr i just did about 20 minutes more tuning and made 375hp at 19 psi....completely stock, head never lifted off.... after i max out this setup the rb is on the way... good luck in whatever engine you decide to put in and do not listen to all these ricers that can not even change thier own oil..

PS: i have less than 4k in my swap... everything was made in house

$4K including the engine/tranny?

okay here's my 1 million dollar thought! if you wanna do a 2jz-gte swap! might as well trade in your car for a sc and do the swap on that! or just buy a damn supra! i derno the reason rx7's r so special if for it's rotary and twin turbo! so....

Your in the land where your only 1psi from blowing your engine and not having enuf money/time to replace it and being with out a car for the next year or 2 hehe. If everyone on here could afford to just replace their engine at a drop of a hat, these types of threads would not even exist. In anycase, I think this site if more of a RX-7 enthusiast type of site. Love the car, not just the engine

P.S. anyone know how much a RB26dett weights???

I'm gonna find out the weight on the the RB26 very very soon I think trying to actually fit and work the AWD will be the biggest thing in engine swaps in a looooong time.

I've got too many ideas and not enough FD's. Anyone wanna donate an FD to the cause? I hope this guy doesn't flake on me that i'm buying 2 more FD's from. Neither have motor's so they'll be perfect for the Frankenstein experiments

Why would you want to put AWD in it?

So why not through a V8 or Supra motor in a 1st gen. or 2nd gen.,...how about an RX2 or 3 or 4????? I see more and more guys that like FD's caring less about what makes the FD better then all generations and more about looks. The FD is one of the very best handling street cars ever made. The rotary helps make that possible with exact 50/50 weight distribution. As far as reliability, The piston engine allows more room for reliability error from the owner. I've seen many rotarys in excess of 200k and running strong. But many do not have the time or intrest to baby their car with the special needs of a rotary. Note: Of course, turbo rotarys are more prone to failure.

In any case, Good luck to all.

I dunno.....just being silly more than anything It does sound really cool though. A Skyline drivetrain in a car that weighs almost 1000lbs. less would equal a truly sick car don't you think?

talk about an oxymoron......

Yes including engine and tranny you can pick up sr engine/tranny for under a thousand dollars...

a supra making 950 whp on stock internals?! I SERIOUSLY doubt many people are stupid enough to try that. 950whp is what? like... 1200 or so hp at the flywheel? a 2jz wouldn't last long making that kind of hp on stock internals. I'm very very very skeptical about that claim. I do believe most supra guys strongly recommend upgrading the internals at 600 or so hp. You're claiming that the stock internals are good for TWICE that.

Bridgeported

Do you want me to find some dynos to prove it to you? Just a quick stop over at the Supra forums and I'll have them if you want. I"m not saying everyone does it, or you can drive down the street and find someone... but there are guys around that have over 900 rwhp on stock internals and have been running like that for a while (over a year) with no failures yet... not sure how reliable it woudl be though.. can't be that reliable. Remember, Toyota is known for overbuilding their engine internals more than any other company is.

Putting AWD and an iron block I6 into the car would cut down on that 900 lb weight difference between the FD and R34 pretty quick! I would estimated a RB26 & AWD FD swap (done properly) would bring the stock weight up to 3400 lbs. So basically you have a Supra. Hmmm.
AWD is just useless additionaly weight and one more thing to go wrong. Helps you for your launch, then hurts you after that.

there are a ton of 2j's making over 700 on stock internals we personally help set one up that made 770wheel, and i am sure a few have made over 900.... also your driveline loss calculation is a little off it is roughly 1111 at the fly with 950 at the wheels

Generally drivetrain losses vary depending on the cars power (I can't explain why).
000 - 400 rwhp = 16-17 %
400 - 800 rwhp = 14-16 %
800 - XXX rwhp = 12-14 %

I've heard rumours that some extremely high powered drag cars (like 1500 rwhp) only lose 11% through the drivetrain, but can't confirm. this.

I still don't understand why there would be a variation dependant on the engine's horsepower. I would think it would be a set value for a certain drivetrain... like one rx-7 would lose the same % as another identical one with more power.

skunks

there are V8's in first and second gens.

The 50/50 weight distribution is still valid for a fd with a V8/LS1 seeing as they only weight 50 lbs more then a stock fd engine and all that weight is before the front axles. I doubt that you will lose any handling (especially with brian's bumpsteer correction fix). Secondly, the 50/50 weight distribution is only good when at a dead stop/not on the gas or brakes which you will probally be doing so in a corner so that does not really make a difference. FD with a V-8= Ultra relible (engine as well as tranny), great handling, great braking, very good looking, light weight and extreamly fast (both in acceleration and top end) car. What more could you want? (Note the cost is not that bad either )

a 2jz-gte in a fd *drools*

Chronos

how much do you pay for non functional FD's?? I was considering making a dedicated track only FD...until I found out about the Diasio 962R, but I still might.

Chronos

Skunks, go give your V8 debates to any race prepped FD. The 13B can weigh significantly less when w/o all the bullshit that comes on it stock.

You probably don't want to hear this but my 94 Silver R2 cost me $10k 4yrs. ago.......my girls 93 VR R1 cost us $4500 shipped off of Ebay 2yrs. ago (rolling chassis).....my 93 BB Touring cost me $1500 (wrecked front but motor still good) and the 2 that i'm getting next week are $3500 for both. One is a 95 white Base with no engine but perfect everything......the other is a 93 VR R1 with no engine and it's missing the hood and front bumper.

So i've been pretty lucky with all my FD experiences.

I've still got over $100k into the 94 R2 and her FD even with the low buying price. That number will go up considerably here in the near future as we near the firing up phase of the 2.

Thanks guys for your inputs.
Bridgeported -- you are wrong a supra motor can only support upto 550 HP on stock internals.

Red-Rx7 -- Thanks for your input, it helped alot. I'm planning on building some of these things by myself, and try to modify parts that are already out there to mate the 2JZ-GTE.

For all you guys that disagree it's your choice, but I and you know that if this turns out well it will be a pretty bad *** car. Now, I just have to find some places where I can get an RX7 with either a blown motor or no motor, with no frame damage, and decent body, and I have to find a 2JZ-GTE engine and tranny.

Like Red-Rx7 said "Need a computer to run the car" can I just hook up an AEM ECU to the Supras wiring harness and use that to run the car? Im planning to use both the RX7/Supra wiring with a custom wiring kit from Painless Wiring. Also, What rearend should I use? Supra or RX7? Something else?


Thanks guys

tnt

I amsorry but you are wrong on this one like I said we help set one up that made 770 rear wheel on stock internals.... either way this is a good argument to have

93BlackFD you should really try and by all the FD's out there it would be your lifes work. But just to tell you I am with you on this, I love the rotary engine.

BlkonBlk

ok RK just use the rx7 rear end and get a new drive shaft made it will be cheaper, considering you can get the drive shaft made for like $200-300 well at laest that is what you can get it made down here in texas for.

redrotorR1

My one thought for this increasingly stupid argument. GRM tested a stock 2JZ-GTE engine and made a little over 700RWHP with just some JE heads. While true you could make 950RWHP on stock internals, it won't last for long. Because you're doing it through boost and not by increasing displacement, lift, or duration; I guarantee that you'll spin a couple bearings, crack a head, or crack a connecting rod before you approach "it's been reliable for xxxxx". Toyota engineers might have been gung-ho about this engine ... but 300% tolerance? .... HA, can I have some of that crack you been smoking?
