i just wanted some slightly simpler info. what would be involved with a non-turbo to turbo swap? i have an 89 gtu and its not exactly a powerhouse (although exceptionally fun to drive). everyone else is talking about big inch piston swaps lol, hope mine is easier to find an answer for. thanks guys

One of the easiest swaps to do.

Of course, you'll need a full TII drivetrain or a custom driveshaft. Drivetrain = engine/trans/driveshaft/diff/axles. If you go the custom driveshaft route, you only need to source the engine/tranny.

As far as electronics go, you will need a stock TII ECU or a standalone system. an 89-91 Turbo ECU will connect to your harness with no problem. The 6 port actuator wiring and VDI wiring use the same ECU pins as the TII knock sensor and wastegate control. Break out the wiring diagrams and compare to be sure of which is which.

Other than that, it's a bolt in solution. I did this swap back in '02 and even let it run and idle on the non turbo ECU.

This is a VERY simple swap although it takes a lot of work to replace the whole drivetrain.

ok you call it simple but if it takes a lot of work then thats a small contradiction...sry to be picky but i dont want to risk ANYTHING going wrong, i try to be extremely particular about my car. i understand the drivetrain and electrical conversion may be pretty straight forward but what i dont understand is if theyre so straight forward then where does the "lot of work" come in? if youre only speaking of the physical aspect of putting it in and not doing any welding or something that takes outsourcing then i dont consider that anywhere NEAR hard work...at the same time i want to make absolutely sure that everything pretty straight forward and if not then i would like to find out every aspect of the swap from step one. the help is very much appreciated and im sry if i may come off as slow, however, im pretty new with rotaries and would like to do it right, not to mention im obsessed with my car and dont want to rik messing anything up at ALL. once again, thank you for youre help and if theres something you dont care to explain or dont have the time please point me in the right direction

What I was referring to was the amount of physical work interchanging parts. Everything bolts and/or plugs in with the exception of the couple of wires I mentioned above. It just dawned on me two more swap specific parts: Switch to the TII clutch master and slave and you *may* need to lengthen your TPS wires. Mine were tight, but didn't have to extend them.

It's cake compared to a transplant such as a V8 - Spending hours mapping out the Mazda wiring diagram and cross referencing it to the donor's wiring diagram... custom fabrication of radiator mounts, building custom hoses and high pressure lines, etc.

So the NA>TII swap is simple as in "It bolts right in and plugs right up." Having to replace the whole drivetrain is where the hard work comes in.

Tell the <edited for flaming> thread starter to check the FAQ over in the 2nd generation Forum........

ok i appreciate he info LT1. i did a bit of asking around and i was also wondering about maybe a 3rd gen swap? heard its considerably more difficult but i think would be worth it. anyone happen to have any info on this? i heard there was a bit of motor mount relocation and naturally the transmission would be a necessity, and i also heard the rx8 6 speed tranny would bolt up as well.

FAQs, read them, man. A 13B-REW swap requires a lot of customization, not as much as a V8, and more than a TII, since that's pretty much a totaly swap of all components.

you cant even do the most simpliest task - search and read
what makes you think you could do anythuing else?
bring the damn car to a shop or something... a reputable guy is rotary rescurection... kevin landers in tennessee

The swap would be hard (for an FD motor) And a RX8 tranny will bolt up but will break in 5 min

i could easily do the search slpin, however, i would prefer to just ask someones who knows something of what they're talking about. besides that i apologize for not doing the "most simpliest task" but im usually pressed for time and i just prefer to type a quick question and post it. maybe i should just *** it up without trying to find out anything at all? thank you, once again, everyone who took the time to give me a straight forward answer and thats an absolutely beautiful car btw LT1.

LT1 isn't 100% right, at least in terms of simplicity.

You don't need the TII trans, driveshaft, rear end, axles and what not. I am currently using the N/A driveline, and all is good. Just don't do any drag launches. The only thing you need drivetrain wise in that circumstance is the N/A flywheel bolted to the TII engine.

Good luck. The swap is very easy. Don't let anyone tell you different.

You ever go to the old autoross events they used to have in Hougton at Michigan Tech?

Anyway, back on topic.

Using the N/A driveline is fine if you leave the thing pretty much stock (you'll at least want a better clutch though), however if you decide to modify it anything at all beyond stock, go with a TII drivetrain.

LT1-10AE

Which is why I mentioned the full drivetrain swap

Anyone who's looking for more power will never be satisfied. Better to build it strong enough to handle anything you throw at it than have to worry about things breaking if you step up power a notch or two.

Actually in the search you would have found a step by step swap info........Quit wastin bandwith.....no one is gonna hold your hand and talk to you over the phone like its Mister Rogers neighborhood....and take you step by step with the swap!

rotorwannabe

i wasnt asking for a step by step i more or less just wanted to know if the swap was as straight forward as i figured it would be. also i have a stage 1 act clutch kit thats been already added to the car, would this be sufficient for the tll? i found a jdm motor, supposedly, for 1,250 that is supposed to only have 25-50k on it. its the best price ive found so far, does anyone know where i might be able to find better? how about a transmission? thanks guys, for your help, and please excuse my elementary questions (i AM new with rotaries and have found myself quite obsessed). i plan on tearing down and rebuilding the motor in my garage with one or two upgrades while im at it, so if you find me irritating now, lol try to just flat out ignore me in a month or so

try jdmsource.ca/v2 you can find a t2 longlock for a bit cheaper than that.

rotorwannabe

a bit cheaper? you may have just saved me 5-600....thanks bro
