I've recently been driving an LSX swapped one. My BF just did the swap, however my FD is still and will always be rotary.. We both are on the same coilover setup.
Sometimes I drive his car so he can tune or I am designated driver. You'd be surprised. The car feels very centered as the transmission is the heaviest part of the car. What surprised the heck out of me was the turning radius, much tighter than mine. I was able to pull a U-turn I would not have otherwise with his old setup or my FD.

BTW his car only weights 150lbs more than mine. A tad shy of 3k.

All rx7 owners want their engine to last a long time, not just you lol.

Problem is is that the rotary is NOT error proof. One tuning mistake and the engine is done. Could be one spike in boost on a cold night and the engine could be done. Overheat the car once and the coolant seals are done.

Owning a rotary car is a very tedious job. You have to be on top of it and always giving it attention. Kinda like having a hot gf lol. Turn your back once or slip on it and its doing something bad lol. Gotta stay on top of it is basically what im saying..

People are against swaps because fd's are rare as it is, to see them getting totaled, then seeing the remaining getting swapped, kinda hurts what the rx7 is about. If I had to guess id say already 25% of all running fd's have a piston engine..

RX = Rotary experiment. For me, its that simple really.

Like 1QWIK7, its like having a high maintanance superhot mistress. Treat her nice, be on top of things and do things right the first time, and you will be provided with perfection unrivalled anything else.
Fnuck it up once, and she wont just bail on ya, she`ll run off with all your money, AND tell the wife at home about it too

You have examples of people going through 4 engines in a year...
and you have people doing 500whp+, racing, tracking and dragging the hell out of their rotaries, AND uses it as a daily driver year...after year....after year...! They MUST be doing something right, something the first group fail to do, rite?

14lbs boost puts down 458 to the wheels at 19lbs puts down 542.

I just got this car last Saturday, they guy included the DYNO sheet. I needs a better tune for sure and I want to run E85 with it, also do a better intake some other stuff it will be more around the 600hp range, perhaps more. We will see.

All the internals components have been upgraded to high end ****.

The beauty of this engine is it can handle a 1000HP and not break a sweat. So I am happy about that.

The car is stupid fast one it spools, I have a VR4 Spyder twin turbo, and those babies spool up allot quicker and continue to pull thru. But this thing suck you in around 4 thousand rpms. Stupid question NEWBE, but is there a yearly gathering and when/where is it.

Youre fine with 600+hp, ive seen that in many 1JZ's with Haltek and E85 setup.
Any more and your wasting horsepower.
You dont need beefed up internals to reach that number. Why did the previous owner bother with building up the internals on a 1JZ when he could have spent that money on a 2J?

What kind of tranny are you running? Anything more than 500hp and you will need the V160 tranny. R154s and W58s cant hold that much power.

I have a SC300, so i know my way around the toyota family

Let me ask you a stupid question I just haven't had time to do the research what is the difference between the 1jz and the 2jz.

Thanks.

1JZ-GTE was 2.5 L, short stroke motor offered in the MK III Supra, Soarer, and Cressida models. It was developed initially by Yamaha and transiotioned into Toyota Design. Offered initally in parallel twin turbo, then single turbo. Last iteration had variable valve timing (VVTi) with single turbo. Internals were intially forged, but i dont know if Toyota changed to cast later on. The engine was used from

2JZ-GTE was 3.0L, long stroke offered in the Mark IV Supra and JDM GS300. It had a sequential twin turbo setup. Internals are cast iron. The motor was developed shortly after introduction of the 1JZGTE as a direct response to the Skyline RB26DETT. Ironically the Supra was the second vehicle to get this setup, the first being the GS300 (Aristo)

Some say the basic difference between the 1JZ Motors and 2JZ GTE Motors is how much money you want to spend and how much power you will get out of it.

Still no matter what yo do to a 1JZGTE, it will not see 1000hp.

Your man's car is sick! Followed the build thread all the way through. Our bump steer tie rods are longer than OEM, so that may effect the turning radius. But, I'm not sure what you are trying to say to me. The Toyo motor carries wieght higher in the car than the Chevy. Also, from what I have read and seen, more of the motor sticks out in front of the towers than the Chevy, and the ENTIRE 13b is tucked behind the shock towers. That is why I'm curious about how this thing is going to handle. My educated guess is worse than an Ls1 and WAY worse than a 13b.

And, the ONLY reason I have a v8 is due to running my poor 'lil guy to about 240* during one of my HPDE events. I will NEVER fault the rotary for anything. Build it right with $$ and it conquers all!

I know this is not a quantified measurement but I guess the toyota inline 6 would be roughly 2 cylinders longer than a v-8. I would figure it to be taller as well since it has overhead cams and the engine is vertical and not angled like in an s2000.

I think the 4 cylinder turbo from the JDM 240sx would be a good swap. I'm sure the subaru sti engine is a little wide but it would certainly be short and low if it could fit. That would be good for handling if it were a possible swap.

So check it, I talked to the guy who I purchased the car, and it has a 1JZ top end and a 2JZ bottom end. Whats your input on this.
