Should be able to pickup a half cut for 2.5K - 3K
Mine was about that much from SSS here in Sydney.
Replace all the rubber seals too! and take the rear cross member off the half cut too!
Though some here don't like to use the newer rear cross member which makes the car more stable or 'pacifies' the rear during corners.

Good Luck with the conversion! very much worth it imho.

Yep - get it through Gorilla Industries, and you'll need to run a few wires to it from the ecu. (The pickup sends it to the ecu and the ecu sends the signal to the cluster.)

While your at it, don't use the stock intercooler - buy a quality sidemount one as its easier to install with the engine out.

Make sure u use the Gen 3 shifter cables off the halfcut (they are slightly different length to N/A ones) and try and source a gen 3 gear shifter - it probably wont come with the half cut.

Not sure whose good for halfcuts down there, I got mine from a shop up here (High Tech Tuning) who know their stuff and have actually been to Japan and source quality halfcuts.

I've had mine for over 2yrs and the biggest problem I've had was a broken a/c belt (touch wood). 1990 is fine - mine is 1990. You do need to either change the cluster (to electronic) or change the pick up in the gearbox as the gen 3 gearbox is for the speedo is electronic.

Hey Tim,

I did my own conversion from the NA to Gen 3 3sgte with a halfcut from Japan, and no joke, the hardest thing was wiring up the ecu + loom along with making the cluster work. Everything else was straight forward.

Everything just went straight over - however, I will say to do the timing belt, water pump, idler bearings before you put it in - so much easier with it out and its good to have a peace of mind. Check the clutch as well, mine slipped massively so I had to change it after I had it running in the car - bit of a pain.

I have a heap of info on gen 3 swap, PM me your email address and I'll send it through. I went off swaps on mr2.com, they actually have some great info.

Thanks man, 6.5k isnt too bad, considering it contains everything you need. the Mr2 i have now is so tidy i would rather do the engine conversion then sell it.

also, benefits of a snorkel? i havnt seen many people running them :\ i rekon they're sweet though

for the 3/4 cut i paid about $6.5k from memory but it had almost everything, check my build thread for all the details.
Conversion was AUD GEN3 NA to GEN3 Turbo which is easier than what i've heard. I also had a mechanic do mine as i'm not as gifted as some of the guys here.

You will need to read the other guys build threads here and overseas to get a better undestanding of their conversions and what issues they had encountered.

Hope that helps mate, best decision i have ever made was going turbo.

i got my half cut / well 3/4 cut from Prestige Motorsports some years go, they are in Queensland.
There should be many others you can find that will help you bring one over.

If you buy a gen3 MR2 half cut you will have almost everything you need. Just buy a new Walbro fuel pump and your set.
Everything will just unbolt and swap over.

I haven't actually done this swap but you will find stacks of info on this forum.
