    Going Japaneese in a GT

    Has anyone looked into putting a Toyota or nissan four cylinder engine and five speed transmission in a GT? It seems to me a 22R would be a great candidate with a five speed. Plenty o fperformance parts available and these engines and trannys are plentiful Any thoughts???

    japanese? tsk tsk, why not volkswagon or something european? the 1.8T's are a pretty fast 4 cyl... just the weight of volkswagons kinda hold them back, not like our little GTs

    I maybe wrong but I think I read that the Japaneese engines turn the opposite way that the "Normal" car turns. So that a Japaneese engine will not "mate" with a European or US Trany and a Japanees Trany will not "mate" with a European or US rear end.

    With that said, you would have to use the whole Japaneese drivetrain not just the engine and trany when you would put it in a GT.

    It would be a lot of work to do (more than what is done with a V-8 conversion), If you wanted to go with some sort of Japaneese engine I would go with a rotory conversion (That has been done and has a lot more advanagaes than the other Japaneese engines). It is lighter and puts out more power per pound the most other engines!!

    Only Honda's rotate the wrong way, but not the S2000 engine.

    And I saw a GT on eBay a while back with a Toyota 1.8. Which should be somewhere here in the Engine Swap Forum (old habits die hard )

    You betcha!

    You can build the "Axis Of Evil" Car, as one member put it. German Car, Japanese Engine, Italian Interior.

    I think if I had an Opel with a solid running 1.9, I would stick with that and improve upon it's performance. Original GT's are hard to find and will be a great investment and collector's item. But... if I had an Opel with an blown engine (or no engine), then I see going to all the work putting another 1.9 in it's place is pointless. Might as well spend the money on a more recent powerplant that has aftermarket support, more reliability and (usually) fuel injected. Taking something as beautiful as a GT and giving it a beautiful engine to match is the ultimate combination.

    I'm mounting a Nissan CA18ET 1.8 litre 4 Cylinder Turbo engine into my GT as we speak. I will be welding up the motor mounts within the next week and working out all the fitment details as they occur. I slid the complete powerplant under the car, and everything matches up really nicely. The only kink will be the shifter location, which will be about 5 inches farther back than stock, but that can be accomodated for by using a forward bent shift knob like the ones found in a 427 Cobra.

    So, in conclusion, all the power to you. Do what you think is best, and always remember to keep it simple. People with big dreams often end up trying to give the car away in a half-stripped state because they can't finish.

    I can verify that mazda rotaries turn the 'right' way


    Why not turn the Honda engine 180 degrees so the water pump faces the firewall? I had a Renault like that once (from the factory!!!)

    I drive a Toyota, a Volkswagen VR6 and an Opel 1.9. But I don't think they really get along. Best to keep them separated.

    "Humor"? I thought that was the standard Texas greeting?


    Since Hondas turn the 'wrong way', they make excellent swaps into rear engine Fiats.......

    Mazda Rotaries have been done successfully numerous times. But old rotaries are getting harder to find in good shape, and parts are getting ahrder to get as well.

    The one I have been looking into is the 1.8L Mazda 16V in the Miatas.. 120 to 150 HP.

    SmileStirred up some S*#T this time

    Holy Moses!!! It was just a question. Baronbors, where I'm originally from (the south east), your comment about a rope and tree only come from those who wear hoods and robes with KKK embroidered on them. Boronbors...not calling you a robe and hood wearing member of the KKK... not my style...just haven't heard that slightly disturbing expression in many moons. My GT is original and I plan on keeping it that way but you never know when you may run into a motorless builder. There are plenty of performance parts out there to make an aluminum block/head japaneese four or six cylinder engine really scream and the weight to horsepower ratio in a GT would be outstanding in my opinion. VW engines are good option as well but not as plentiful. Didn't mean to offend anybody...I live by a simple rule..."Don't sweat the petty things and always pet the sweaty things!!!"

    I don't know, mixing of car heritages, can result in some nice cars.

    Heck if it weren't some American muscle being put between the thighs of a sweet looking Aussie born of German heritage, I wouldn't have my GTO.

    Apparently she worked for Holden and blackmailed Bob Lutz into getting Holden some business.

    I saw a SOC toyota in a GT on ebay last year, as well as a 4cy Nissan. Rotory is the way I want to go, but as charles said the motors are getting hard to find.

    The Toyota 4AGE motor would be an awesome swap, but I don't know what tranny you can use with it.

    I have also been looking into Miata motors, they seem like a good fit and I have found them for as cheep as $400 on eBay. But judging by the support here I may just go the V6 route.

    Thanks for the inputs Chris. The reason I was leaning more toward a 4 banger over the v-6 is because I would like to keep everything under the hood. I have been looking for a motorless builder close to home but have come up empty so far. Definitely want to keep the 72 I have right now all original. Too noce to chop up.

    GM 60-degree 3.4 V6 (pushrod) will fit under the hood, and between the fenders... and I have a spare one...

    (The Toyota 4AGE motor would be an awesome swap, but I don't know what tranny you can use with it ) I agree there doing some big things with that motor in here the uk there using it in a lot of kit cars so there must be some tranny to use with it
