hey guys! so i'm planning to do a n/a to TT swap for my zed, i'm going to be using my n/a MT gearbox on to the TT motor which had an auto box, and i was wondering what i'd need for the swap? i have the whole motor, wiring and all because i'm getting a shell with the engine and pretty much everything else, or could i just use my n/a wiring on the engine, and what else do i need for the swap?
Can you get the NA flex plate, because its a different diameter than the TT one, and the starter motor is mounted to the gearbox which I think also has a different diameter bell housing, so it throws everything out of wack
Search would give you all the following answers: -na engine loom on a tt motor is fine -na manual gearbox is the same as a tt internally, just needs the bellhousing shaved to fit a tt flywheel and starter motor shimmed out -complete running shell will have just about everything you need for a tt swap
ahhhh okay thank you! so where would i go, or what would i need to shave it down and how much would i need to shave down for the TT flywheel?
only a couple mm. Use a file or grinder or something like that, you really don't have to take too much off.
Make life easy. Use the na manual box with its na flywheel and clutch. Bolt all this onto the tt engine. Insert in car setup for na manual. Wire as normal. Swap ecu. Install aftermarket boost controller. Off you go. This will get you driving. If you want to upgrade the clutch. Find a heavier duty clutch to hold the power but what will bolt up to the na flywheel. Alternatively. Source a tt flywheel. Use a tt clutch. You will however then need to notch the internal diameter of the na box bellhousing to accomdate the larger diameter tt flywheel. Them use some 3mm washers to space the starter motor away from the na manual bellhousing. I think it's 3mm, but have a search and you'll confirm it. All you will require from the tt donor vehicle is the engine and ecu. Remove the automatic box flex plate. Remove the spacer from off the crank. Insert a brass bush or nismo bearing for the na manual box input shaft. It will all be pretty simple once you start playing.
+1 to Chris' comments above. Brass bush is the go. Roller bearings have known to fail after a period of time due to a lack of lubrication.
Im going through similar procedure myself and have almost acquired all parts. If you went with Sanouske's TT flywheel path, Z1 sells a starter motor spacing plate for carrying out the starter motor interchangeability. Seconded on the Nismo bush, use a brass bush only. If your changing to a half and half TT manual drivetrain, you will probably be chasing for a TT Clutch booster and etc? Don't quote me on it, but in the case of the booster's requirement , my memory says that the TT 5 speed engine draws more vacuum functionality or the increase in power is harder on the leg when gear changing...? You may get by without it ? But if you need the booster, you'll be needing the TT clutch pedal to suit.
You can get by without the booster. Not really needed. Makes the clutch really easy o push in, but it's not excessively heavy without it.
you guys always amaze me! (': I'll use my n/a flywheel and clutch, I'm not exactly going for power at the moment, as long as it drives until I save up for a proper hd clutch and all! do you reckon I could us an ecu from the tt auto, or will I have to buy a tt manual ecu?
Auto ECU will be fine, I'm using a NA auto ecu with nistune in my TT manual A quick wiring mod will fix the timing issue at idle.
Mostly, it's just all the stuffing about with new inlet piping, aircon condensor swap over, bending PS lines, minor wiring changes etc etc.
well the new inlet piping shouldn't be hard, i can swap them over to my zed easily! is swapping the air condenser and all those other things hard to do?
Not particularly. It's all rather straight forward when you start removing and transferring the parts over. The ac pump. If you crack or remove the lines, be careful. As you'll vent the gas/oil withing the system. You're technically not meant to vent this to atmosphere. But you won't be the first. It makes a mess so be weary of what you're doing and where you're doing it. Ideally I would get the systems evactuate of the gas/oil first. Properly. I to be honest actually thought they were interchangeable between the engine variants. As I swear I got a replacement compressor pump from a tt and put on my na auto zed. Back in the day. So what I'm saying is you may be able to keep everything connected on the na zed and just shoe horn the tt engine in. And yes a tt auto ecu will work fine. Either way you'll work it out as you go. Any other issues just ask. Best get a good mental picture before playing with it all
