ok I'm starting this thread to gauge the intrest in doing the 2jz swap
I am considering doing this swap for others once mine is done.
Of coarse I dont know how much the total cost would be yet but I know it will be less than some of the turbo kits out there and have much more potential for power

The swap will not be for every one and I know that. This of coarse will not be the ideal setup for track use either. But all that ok be tested when mines done. I will be doing 1/4 mile races, and some autocross stuff. And will get some videos of it all. I also have some friends with stock 8's and close to stock 8's to test side by side

I am a toyota tech and will be doing these on the side
I dont know a turn around time yet either. But I will need all the parts or you have all the parts before I take a car and it will be only one at a time

This thread is just for gauging basic interest

the link to the thread on my swap is in my sig

please vote and post your opinion



and please don't let it get off-topic or hateful. if you don't like the idea thats fine

Mad_kidd

how about offering a 2jz swap kit?

HeavyMetal699

I voted no.

The reality is that I don't have the money to do any swap, or even a turbo in the near future.

If I had the money and just had to swap out motors, there are other engines that are newer and better suited to the car IN MY OPINION.

With all that said your swap looks completely awesome. It seems to fit exactly what you want to do with the car. Good luck!

That is something I have considered but I dont have the means as of now
but is somthing I will be looking into

Bindon

How do you reckon that swapping a RJZ will be cheaper then a turbo kit?

You need a custom drive shaft, braces, tons of stuff, not to mention the motor itself...

its a really tall motor.

wouldnt an ls-x keep the CoG down lower?

sixgen3sgte

not all turbo kits, i said some of the turbo kits out there
such as one of the MAzsport turbo kits that cost like 10K

and because my swap will have cost me about 4500 to $5000 not including the turbo or intercooler, so i know i could do it for under 10K, with a basic turbo upgrade and around 400 hp with a swap pushing 600hp under 12K easy

now thats not HKS turbo's or a Full Race manifold or all the extras that couple easily be turned into a $30k swap but it will be reliable and make good power for the street



motor set, trans and the rest of the drive train is around 3K if you shop right

if you go with the six speed look to spend around 7000 - 8000

a single turbo upgrade could be done for 1500 easily

for a full kit with a name brand manifold and a large ball bearing turbo your looking at 3000-6000 if you really want to spend the money



but if you just want to start out basic

i Promise i will be able to do it for under 10,000 and you can always upgrade later on on your own

you can also sell the stock motor to knock even more off the cost of the swap

and this could be done in automatic 8's much cheaper, just not with lots of power, but a 350 whp auto 2J would be much more fun than a renesis






and yes there are some other great motors out there, and i want to explore some of them, but the 2J is going to be the cheapest motor you can find with its power potential and reliablity in my opinion

I think if you could get a rwd tranny for it, a modded mazda 2.3 turbo motor would be cool

there is not much room, so a V motor would definately be much more difficult and much harder to work on, but is doable, i just don't like V8's (at least domestic ones) i would much rather go with a VQ35 or something along those lines, and i think there is someone in AL looking to do a LS-x motor

sixgen3sgte

bump, more opinions please

RX + pistons = blasphemy

I'd do a 20b conversion before I'd do a 2JZ, but either way good luck with it. I'd be interested in seeing such a car in person.

BlueRenesis82

Dumbest thread ever.

a_ahlan

+1.

Dude, you bought the wrong car. the only engine swap I can think of is 20B for now. And 16X when its available.

Red Devil

If I were throwing in a piston engine, I wouldn't go with the 2JZ...there are better options out there than that aging architecture. LSx series, or what would be cool would be Mazda's DISI engine...I'd throw in a VQ before I would a 2JZ...

what about the bmw s52 engine? its another inline 6.

333hp, n/a.

i'd actually consider that engine if i wanted to do a swap to a piston engine.

SlideWayz

Sounds good to me.

What about an engine out of an Evo IX? Wouldn't that be a smaller form factor & thus easier to shoehorn in?

dozer

iTrader: (3)

nah i would only do a 2jz in another car, the rx8 platform stock just HANDLES to good, anything bigger and it only becomes a straight line car....no fun in that, just my 2cents

sixgen3sgte

i never said that the 2JZ was the Best choice, and i certainly never said it is the only choice

but in my opinion it is the best choice for power to price ratio
plus it has a huge aftermarket support

an LSx motor could range from $3000 to $10,000 depending on what what variation
and a VQ35 out of a Z is not cheap either

and some times an aged motor is better any way, it has been tried and tesyed and proven it self for a decade now, i doubt many people would argue reliability between the 2j and 13B or any rotary

kersh4w

iTrader: (3)

sorry, i meant the bmw s54 engine. they can be had for about 5-9 grand for a decent engine. as i said, the bmw inline 6 would be preferential to the toyota inline 6.

anyway, good luck with your swap. i'd like to see a 2jz swap into an rx8 that actually comes to fruition.

bse50

Negative,
the rx8 is all about handling. Tune your engine indeed!
We have a very good chassis and a unique engine. If you take the engine out and add a heavy inline 6 you kill the chassis factor as well, thus having just a drag car.
To me it makes no sense, like the swaps on the poor old fc3s

SlideWayz

Yeah, but there are hot 4-cyl engines that don't weigh too much more than the 8's engine.

There's also a few tricks that could be done to keep the balance close to 50/50 and the handling sweet.

I'll bet no one or almost no one will get 100k miles out of a turbocharged Renesis that's making 300+WHP.

The rotary is cool and its powerband broad, but wouldn't it be nice to have this car make good power reliably?

bse50

Yes but wouldn't it be stupid to mess up with a car that is bought mainly for the engine feature? An rx8 without a wankel inside the bonnet would be just an "8"!
And then, reliability is not always a big issue. I had a look @ mysql's rebuild and the engine was in fairly good conditions! Moreover, revs help a lot on the track so swapping for another engine would be another useless waste of money for me, but that's my opinion

BlueRenesis82

This car does make good power reliably, and if you think you need more power you need to learn how to drive.

sixgen3sgte

ok, I said i wanted people's opinions not insults
lets ease up a bit guys, lets respect each others opinions
and like i said to begin with, this is not for everyone



and i did not buy my car for its engine, i bought it becasue it was a sporty car for a great price (i bought used), has great looks, and 4 doors (how many sports cars have that, definately not a supra).

and the only downside to buying the car was the lack of power,






it may make good power for you but not for me, and i do know how to drive.
in fact pretty much every review of the car any magazine has done, the only bad part about the car was the power, look it up in car and driver, or some of the video test drives on you tube

i'ld bet that the rx8's power is the only reason why the 350Z is more popular (because it makes nearly 100 hp more for the same price)

and if you think it makes good power why do company's make cars with 300, 500 and more if 230 (mabey 180whp) is enough

there is no such thing as enough for some people
but until you feel what 500 hp feels like you don't know what your missing





either way, i hope to prove some people wrong with this, but there is not much point arguing until it is done and i have some videos, times, and numbers.

but like i said please keep the insulting to the minimum, but all opinions are welcome.

thanks all for looking

bse50

we might lack power compared to other cars but what about lap times?
Take a look at any z06 vette on laguna seca and look at the speed at each corner, then take the rx8 and notice how similar, if not superior, its turning speed is.
I know that 'vettes mount leafsprings like the old fiat 500 in the '60s but you're talking about 500hp and that's an economical car with 500hp.

Another Reni, 16x, or 20b would be the ONLY swap I'd ever do.

BlueRenesis82

Well, I am glad that you think that the car doesn't have enough power, and would prefer to hang a cast iron inline six forward of the front axle. That should solve that whole handling problem for you, and enable you to add a bunch of weight to the car. Way to go.
