supra-ireland Posted December 17, 2008 Share Posted December 17, 2008 Are there any issues or is there any extra work involved in putting a vvti-2JZGTE engine into a Mark IV which had the older pre-vvti 2JZGTE in it. I've been led to believe that the sump differs on the two engines. Can the old sump be simply swapped onto the newer engine? -Thanks, Paul Quote Link to comment Share on other sites More sharing options...
D8MOA Posted December 17, 2008 Share Posted December 17, 2008 i dont see why the sump would be diffrent? thay differ when thay fit them to the aristo! i dont see why you would have any problelms fitting it, you would obv need the vvti loom and ecu though Quote Link to comment Share on other sites More sharing options...
supra-ireland Posted December 17, 2008 Author Share Posted December 17, 2008 Is there an easy way of telling if a 2JZGTE engine is a vvti or non-vvti. The engine in question is in a crate not a car. Quote Link to comment Share on other sites More sharing options...
Luka-P Posted December 17, 2008 Share Posted December 17, 2008 I think the spark plug covers are a different colour to the older green-ish type. Quote Link to comment Share on other sites More sharing options...
DaveR Posted December 17, 2008 Share Posted December 17, 2008 The shape of the spark plug cover is the instant giveaway (and the fact that one of them has VVTi written on it...). The one with the bulge on the front of it is the VVTi, the other one is the non-VVTi. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 17, 2008 Share Posted December 17, 2008 Lots of electrical and ecu type issues. The de cat pipes, or first cats are different. The sump is the same. Quote Link to comment Share on other sites More sharing options...
supra-ireland Posted December 17, 2008 Author Share Posted December 17, 2008 Hmm, I think now that what I'm dealing with is an Aristo engine and not a vvti. Thanks for all the advice. So, if it is an Aristo engine, what issues would I be looking at to get it into a J-Spec? Quote Link to comment Share on other sites More sharing options...
Thorin Posted December 17, 2008 Share Posted December 17, 2008 I presume you're fitting a VVTI engine because your current non-VVTI engine is knackered and you can get hold of a VVTI engine as a replacement? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 17, 2008 Share Posted December 17, 2008 Plus you need the FBW throttle pedal assembly. Would be a lot simpler to get a pre VVTi engine, IMO. Quote Link to comment Share on other sites More sharing options...
Robert Posted December 17, 2008 Share Posted December 17, 2008 (edited) one thing if it is an aristo VVTI engine then the vacuum take off for the brakes that you have on an supra is not present on the aristo VVTI intake manifold so that will need to be swapped over. edit: even if it an aristo engine same rule applies with the intake manifold regardless of VVTI or not. Also the water pump is driven by a hydraulic pump system and not by the engine.

supra-ireland Posted December 17, 2008 Author Share Posted December 17, 2008 Yes, I did have trouble sourcing a replacement engine. The one that is available now is a 2JZGTE with a slightly different sump. From reading on here it seems that this engine must be from an Aristo. I can't find any other explanation for the sump variation. I have no reason to believe that the engine is vvti. So, lets says it's a non-vvti 2JZGTE, what complications will arise when trying to install this in my Mark IV? Can the sump be taken off the old Supra engine and simply be fitted to the new one? Which ECU will need to be used? Are there any other issues? -Thanks, Paul Quote Link to comment Share on other sites More sharing options...
Robert Posted December 17, 2008 Share Posted December 17, 2008 Yes the aristo would have a different oil sump. Yeah a supra sump can be fitted instead on the aristo engine. A supra ECU will work, but i think you're AC system won't work unless you get an aristo specfic ECU Quote Link to comment Share on other sites More sharing options...
supra-ireland Posted December 17, 2008 Author Share Posted December 17, 2008 Ok, thanks again for all the advice. So if I'm understanding this correctly... The Aristo engine will work fine, certain bits will just have to be swapped over from the original engine. Also, the sump needs to be taken off the original engine and put onto the new, Aristo engine. Finally, I should use the Aristo ECU, if possible. Is there anything else that I'm missing or should that be it? Quote Link to comment Share on other sites More sharing options...
Robert Posted December 17, 2008 Share Posted December 17, 2008 i would say if you are keeping the stock supra wiring loom the supra ECU should be fine, but then again im not 100% Quote Link to comment Share on other sites More sharing options...
supra-ireland Posted December 17, 2008 Author Share Posted December 17, 2008 I've been reading around on several other forums and the more I read the more confused I get. Some people seem to be of the opinion that you can fit the Aristo engine, plug it into the existing J-Spec Supra ECU and have no problems (bar maybe the AC). Other people say that it's a massive headache putting an Aristo engine into a J-Spec, that it's a nightmare due to issues with the harness and ECU. Has anyone had experience of putting an Aristo 2JZGTE into a J-Spec? I don't' want to go ahead if it's going to turn into a disaster.

Robert Posted December 17, 2008 Share Posted December 17, 2008 i have done it the other way around and it was fine supra engine -> aristo. I would say the only issue will be the AC and that being the worst case. In this weather you won't need it anyways. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 17, 2008 Share Posted December 17, 2008 You definitely cannot just connect a VVTi engine to a pre VVTi loom or ecu. Does the Aristo VVTi use FBW throttle control? If so, more stuff to buy. Quote Link to comment Share on other sites More sharing options...

Chris i am assuming he hasn't got a VVTI now as like you said that is a whole different kettle of fish, wiring wise. Quote Link to comment Share on other sites More sharing options...

If so, more stuff to buy. Sorry for the confusion at the start of my thread. I mistakenly thought that the engine was a vvti. The car is a non-vvti J-Spec and I believe the engine is a non-vvti 2JZGTE from an Aristo. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 17, 2008 Share Posted December 17, 2008 In that case it should be relatively straightforward, especially if you still have the original Supra engine to get any odds and sods off. Quote Link to comment Share on other sites More sharing options...

Nic Posted December 18, 2008 Share Posted December 18, 2008 I fitted a JZS161 Aristo VVTi 2JZGTE engine in mine, but swapped my non-VVTi head over to make the install a LOT easier. The Aristo does have a different sump, but you can swap the sump from your other engine no problem. The only other difference (from memory) was that the oil level sensor plug was different, but I think this was a VVTi/non-VVTi difference, the non-VVTi 2JZGTE Aristo engine I think has the same sensor.
