TLicense Posted September 24, 2006 Share Posted September 24, 2006 Nightmare. The part list required is obscene. You'd need a donor car to be able to do it easily. Quote Link to comment Share on other sites More sharing options...
colsoop Posted September 24, 2006 Share Posted September 24, 2006 What year is the na manual you have in mind for conversion ? Quote Link to comment Share on other sites More sharing options...
ECK Posted September 24, 2006 Share Posted September 24, 2006 dont do it mate get rid of yer n/a and buy a tt im in the middle of doing the conversion now and wish i hadent started and thats with a donor car alot of work!!!! Quote Link to comment Share on other sites More sharing options...
steve0 Posted September 24, 2006 Author Share Posted September 24, 2006 is it that bad i thought it would been quite an easy conversion as you can get a tt engine for around a grand Quote Link to comment Share on other sites More sharing options...
jackso11 Posted September 24, 2006 Share Posted September 24, 2006 its not just the engine you need though. think of a part of the car that isn't body work and it will prob. have to be changed! Quote Link to comment Share on other sites More sharing options...
dini_the_owl Posted September 24, 2006 Share Posted September 24, 2006 Hi, I have a supra N/a.just in the middle of the conversion myself and its not that much hastle if you can find the bits or have a large pocket....?buying from toyota dealers. some bits are different but if you can find: 2jzgte engine not jdm with all harness and 5 speed manual ecu you can use the w58 transmission of the n/a rear subframe is slightly different but you can use the n/a one just need to buy the right hand side bush for the lsd also you will require a twin turbo lsd twin turbo prop shaft - you will need the end off your old propshaft which goes into the w58 tranny and get this swapped by a drive shaft company- fits great. twin turbo rear drive axles using your n/a rear hubs as they are the same as tt. Twin turbo clutch and flywheel although you can use the n/a stock flywheel the clutch is a must. thats about it,as for getting it in,then think about getting some tt front brake setup,air box or induction kit and fuel pump and better intercooler. power steering pump,aircon etc all the same as the n/a. Brake master cylinder slightly better aswell on tt. andy Quote Link to comment Share on other sites More sharing options...
Homer Posted September 24, 2006 Share Posted September 24, 2006 Rather a lot missing from that list mate! ECU, loom, etc? Also W58 and NA clutch isn't going to last very long, esp. if you go beyond stock boost levels Quote Link to comment Share on other sites More sharing options...
MizTheWiz Posted September 24, 2006 Share Posted September 24, 2006 sounds like it would be easier just to swap the body work over from a donar car Quote Link to comment Share on other sites More sharing options...

Homer Posted September 25, 2006 Share Posted September 25, 2006 sounds like you failed to read at the top m8.....2jzgte engine not jdm with all harness and 5 speed manual ecu No, you fail to realise something rather obvious here 2jzgte with a 5spd manual ecu Edited to be helpful: 5spd ecu = NA ECU, so no good for the 2jzgte Where did the engine loom come from the NA or the TT?

tDR Posted September 25, 2006 Share Posted September 25, 2006 I would say you'll want a jdm 2JZ-GTE considering they're the low mileage ones with the bigger and faster spooling turbo's 5sp manual ECU will be as much use as a chocolate fireguard!!! Both fuelling and timing all wrong considering the timing needs pulled for the turbo's and the injectors are bigger. How you getting on with your conversion Alex? Cheers, Brian.

dini_the_owl Posted September 27, 2006 Share Posted September 27, 2006 Firstly engine was purchased in japan but has been shipped over here by a company i deal with in the u/s, This came with a Twin Turbo loom and 5 speed ecu,so installing the loom etc is no problem,the W58 transmission bolts straight onto this engine with no problems as some of the jap guys have alrady done this for drifting cars because of the difference in gear ratio,slightly better for the tracks where they are situated???,The only thing is that there is a restriction as to how much power you can put through these transmissions if i remember its around 500-550bhp where as the V16x box holds in access of 1000 bhp. All they do is remap the ecu with a better configuration which will better suit the Twin turbo engine so it is not keeping the standard oem settings. As for the N/a ecu i dunno whether it is the same ecu because i have both of them here and they look different and have different part numbers, I will post pics on here and you can make up ur own mind but i wont be using a N/a ecu config thats for sure.

Jake Posted September 27, 2006 Share Posted September 27, 2006 2jzgte engine not jdm with all harness and 5 speed manual ecu engine was purchased in japan but has been shipped over here by a company i deal with in the u/s, This came with a Twin Turbo loom and 5 speed ecu So you bought a non-JDM engine from Japan? How are you going to remap the ECU from an NA to work with a TT engine? Quote Link to comment Share on other sites More sharing options...
dini_the_owl Posted September 27, 2006 Share Posted September 27, 2006 Hi, i purchased the engine,harness and ecu from a company in the states who deals imports from japan, I know these guys very well and they assured me the ecu i have got comes specifically for 5 speed in japan. I also meant to say the "Later jdm engine" in my initial statement so thanks for picking that one up m8, Meaning " To stay away from the later ones with tiptronic gearshift setup" As i understand there are a couple of ways to get the 5 speed box into the jza 80 with a 2jzgte lump, Appart from just using the W58 tranny, You can even run a 1JZgte Transmission from the mk3 supra (R154) which has the same mountings to a jza80 chassis,all you would require is the W58 bell housing to match with the 2jzgte. Infact there are Aristo's in japan with the 2jzgte engine and believe it or not they are 5 speed.....Ive just looked at a picture of one and the ecu looks exactly the same as the one i purchased with the engine....well you learn something new every day. ,so i do not think the ecu is a mapped N/a one, more like it is from an aristo,just to add the Aristo runs the R154 tranny from a mk3 supra. hope this helps andy Quote Link to comment Share on other sites More sharing options...
JustGav Posted September 27, 2006 Share Posted September 27, 2006 I hope you have got a bit more loom than just the above..... Also, I was under the impression (and I could be wrong) that the aristo's were auto's.. However, best of luck with the project and I hope it works for you.

The tiptronic was only on the Auto VVTi Supras. Quote Link to comment Share on other sites More sharing options...
bromy Posted September 27, 2006 Share Posted September 27, 2006 Are you sure about the R154 box bolting straight up as boostlogic sell a kit at $2200 to fully mate this box to the jza80, this price excludes the box btw Quote Link to comment Share on other sites More sharing options...
dini_the_owl Posted September 27, 2006 Share Posted September 27, 2006 Hi bromy, Yeah they do thats right, just want to know if you had seen one? here you are,have a laugh at this support they sent someone, supposed to be high tech replacement cost around £1200,as you can see a Bit of 2x2" box section steel with 4" lips on each end and a 7x4" plate welded on to hold the tranny bush,dont quote me please on the dims...But youll get the 1 piece prop shaft too! Im no expert by any means but you can make the same for about 5 quid and a bit of solder..lol a proper driveshaft company just did mine for £150,i provided both ends and the measurments that was it,24 hr service. hope the pics come in usefull....
