Hope someone can confirm my assumptions I have 2 vehicles both tt Engines and 2+2. The Auto is a 96 model The manual is a 90 model Can i swap engines over? That is Put the Manual engine in the Auto car and the Auto Engine in the Manual car? Thanks in advance. MichaelZ
Yeah you can, but if it's a genuine 96 zed then you'd have a series 2 engine which is 'better' than the series 1. Better to rebuild if it's a bit tired.
Thats what I thought. So I noticed that the 96 TT Engine has a series 2 PTU and the passenger side has less emission stuff. I was wondering how to get the 90 engine to connect to the 96 engine loom? Thanks.
Are they stock ecu's on both cars? Sounds like you are keeping the transmissions in the original bodies, but you will have to switch the ecus. They say an ecu from an auto can live with a manual gearbox, but an ecu from a manual cannot live with an auto box.
If the engines are the same then would not the ECU simply treat the Auto engine as a Manual engine? I am assuming that the Engine internals are identical. That is the engine block and heads etc are identical. Is my assumption correct? I intend to leave the EGR and emission stuff with the car so these would need to be swapped over from each engine. Am I correct? MichaelZ
Auto ecu can be used in a manual car. Your 96 will have the later style heads, lower and upper plenum that are slightly different to the early car. EGR will be the same between the two. The 90 will have aiv's while the 96 won't. Can I ask what you're hoping to accomplish by swapping the engines from each car? From what I've gathered you're not just putting a new engine in from a halfcut but rather swapping engines with 2 running, driving cars.
If you getting a 96 engine, get the loom and ecu to match. There was chenges to loom and ecu. S2 has a boost sensor input to the ecu S1 does not. As well as the cas plug is different, injectors, there was some cam difference, i think with the vct area. However i dont know if a s1 ecu can run an s2 engine.
Did not want to complicate post. I am going to rebuild the 96 auto engine and then place it in the 90 Man car so i can drive one while rebuilding the other. I bought the Auto TT car thinking that the engines were essentially the same block but I now find that the cams and turbos are different so a little bit of work swapping these over and I should accomplish what I want. MichaelZ
The cams are not a direct drop in. If they can fit at all. I know you will need the intake cam gear and cams to match, cant remeber if the actual head is different where them cam sits
Yes they are, you just need to use the s2 cam gears with them. Also I think you'll find it was the us 96 cars that had a map sensor and it wasn't fitted to jdm cars until later on.
you will need an ECU Sounds like a good idea and keeps you in a Zed. If you buy a new S2 wiring harness for the 1990 body and keep S2 engine and S2 ECU together in that car, then most issues will be sorted. To finish off the 1996 body (which will be an Auto) you will need to get an S1 ecu from an auto because the auto transmission needs it. You might be able to swap with someone who did a manual conversion and wants to clear the error from having an ECU that is lookong for the auto transmission. You will have plenty of S1 plugs from the S1 harness that you pulled out of the 1990 engine bay, so you can downgrade the S2 harness to suit your 1990 engine. But you should grab an S2 PTU to suit that part of the harness, because downgrading that bit would be silly. Anyway that is what I remember from my enquiries to do the same, once apon a time.
They all have a boost sensor (up to the 96 or so jdm cars where they went away for a little while) but that only goes to the dash cluster, ecu doesn't use its input for anything.
Thanks to all of you. Good help After listening to all your comments/advice I have decided that my chances of getting everything sorted on both cars may not be worth the trouble. I did not research before buying the Auto TT. Lesson learned. Do not rush into a purchase before researching. I will reassemble the Auto and sell as is and then rebuild the manual and keep it. Thanks again for your assistance but I have come to the less hassle and most economical conclusion. This is the reason i joined the forum. Experience is priceless. MichaelZ
While I have your attention..... Can anyone tell me the year of manufacture for my ZED. i have tried to get Nissan FAST but after 4hrs I gave up. It is TT Auto. It has VTC and no airbags. VIN Number GCZ32505177 Thank you. MichaelZ
Found out myself. Never mind . It is a 1989. Looks like I was duded. Advertised as a 1996 but i am not worried. I did not pay much for it. MichaelZ
VIN: GCZ32-505177 Model: KRGZ32JASHE7 Built: 10/1989 Colour: AH3 Trim: G Roof: Targa Engine: VG30DTT Transmission: Automatic Seating: 2+2
Well that is good news and bad. Engines are the same and you can swap them across and transfer the ECU's. The really low kms on the auto may not be genuine. You should check the condition of the auto's engine because it is probably older than the one in your current car.
