Bit of a random question, but has noone considered the lexus alloy v8?  Remember seeing something somewhere about these being easily adapted to a supra manual box. 4L would make me think plenty of torque, and seen a lexus barge for sale recently for less than 500 notes for the whole car, and less than 90k on it, if I remember correctly.

 i did once consider using the lexus v8 + 2 turbo\'s into supra mkiv, but went for the 2jz and single conversion

[Speedworks]

there is a german guy (//www.asia-unlimited.com) who did a 2JZ swap.

[trotter]

I did do a search on here for 2jzswap, 1jz, and supra engine swap but only got one post with not much info in. I dont want a 1jz I want a reliable, fast, fairly good mpg rx7 as its a daily driver. I dont know what mpg you guys get but £5 per 30min of carefull driving is what I get. The ls engine must almost be as light as the 13b then if the 1jz is only 60kg heavier thats good for 5.7 v8. I don\'t think id go for the ls as the fuel prob would be the same.

here\'s your answer...

reliable - keep an eye on oil levels and water temperatures
fast - it\'s already fast
fairly good mpg - stay off boost and cruise on 5th for a bit each day

...Just keep the 13B!!!

Audi 2.2 I5 turbo Shorter, way lighter that the 1JZ, capeable of the same power, but bombproof with it. I\'m still measuring up and musing, but looks like it\'ll fit in really nicely with no steering rack or bonnet issues. My S4 that the 5 sylinder came out of returned 30mpg rolling average on a mix of motorway and town despite weighing twice what the rex does, and an easy 40 if driven sensibly on the motorway too.

To be honest the thing that attracted me to the FD3S is the 13b in the first place. The exoticness, the noise, the revs. It\'s bad enough wanting to stick some yankee pig iron under the bonnet (no disrespect, and I know they use ally nowdays) but an Audi I5 is a new low..... :Giggle
 
[RANT] It\'s like when Americans buy an old Countach and replace the carbed V12\'s because they\'re unreliable and "ain\'t got enough torque dude" what an ace way to spoil a perfectly good car.
 
If that\'s your cup of tea then fine, personaly I\'d rather subject myself to a weeks worth of genital torture. In fact if I did, I think that\'s what the wife would do to me, in fairness she\'d be right. [/RANT]

Lol. Likewise, I was attracted to the rotary because it\'s different and I like a challenge. I tried to love it, and even went as far as doing a (successful) rebuild myself. I feel I have fair grounds for saying after all I\'ve been through with it, I simply don\'t like the Mazda rotary. If it floats your boat fair enough, but just not my cup of tea at all.
I have a car I like that owes a fair bit of money with an engine I have no love for. It\'s currently running very well, but I can\'t stand the \'what\'s it going to do today\' fear when wielding the key :rollin
For one reason or another (to be fair, not all rotary related) it doesn\'t look likely I\'ll be getting my money back out, so why not sell the rotary, take up the challenge and do something different with it :3gears-lh
There are my reasons for considering a conversion anyway.
The Audi was the other way around btw - Fell in love with the engine, but didn\'t really like the car in the end.

I sold an FD with no engine a while back and I didn\'t have a single serious call from someone that wanted to put a rotary back in, despite it actually being registered as a 1.3 and pre cat requirement. Even I was fairly shocked.
I take your point on the V8 - that wouldn\'t be my thing either - but I feel the smallish turbo I5 isn\'t too out of sorts compared to many other options. At least it\'s not a 2.0 turbo 4 pot It does have one other thing going for it that really appeals to me: Never been done before. :Giggle

If you don\'t like the rotary then don\'t buy an RX. Simples
I don\'t get these people buying Rx\'s then coming on a Rotary club and slagging off the Rotary engine.

Thats a bit harsh, i cant see anywhere were he is actually slagging off the rotary engine, merely stating facts about fuel consumption and the dreaded 60k marker (though many engines have surpast this milestone). TBF the look of the RX7 are second to none and if its that which has attracted him to own one then he can choose to put which ever engine he wants to in it

It wouldn\'t be me though. I love the sound of the rotary on start-up. I could listen to that beautiful sound all day long :3gears-rh

Haha youve kind of lost the plot here, I would bet money that nobody daily drives a Countach, they would be collectors or enthusiasts so they dont care about mpg. Ive never heard of v8\'s in countach\'s only kit cars, but agree that would ruin it putting that in there.
 
The rotary engine is an amazing peice of kit, small, lightweight, powerfull. The perfect ingredients for racing, but in my opinion thats it. It good for weekend fun, racing, second car type thing, but if you wanted to realistically use one as a daily driver, you would have to have a lot of spare cash and time to work on it or get it worked on. I have gone through quite a few cars since posting on here and currenty daily drive a 05 BMW 645 and yes its cheaper to run then the rx7. About 2 weeks ago I drove across europe on cruise control at 110mph for upto 3 hours at a time, now seriously could a rotary fd do that.
 
Saying this I still have an fd in the garage that im building up to use for hillclimb events and for that I wouldnt dream of changing the engine.

Hey lucasl - don\'t spose you have a red J-reg FD with number plate J277? Just that i saw my old one for sale on Pistonheads being sold and the seller was saying they were planning on putting a 1JZ engine in it.

I hope you\'re keeping the FD rotary :wiggle
