miko_supra Posted September 26, 2007 Share Posted September 26, 2007 Has anyone done an engine swap from n/a to TT by themselves? what does it envolve? Link to comment Share on other sites More sharing options...
JustGav Posted September 26, 2007 Share Posted September 26, 2007 Yeah I did... To be fair, if you have the space it isn't too difficult. You will definitely require an engine crane. I went for the option of undoing the front subframe and lifting the shell over the top... But I was doing suspensions change and hub change at the same time.

miko_supra Posted September 27, 2007 Author Share Posted September 27, 2007 Cheers, so supposing i stick with a n/a 5 speed box, will it still bolt straight on or are other changes needed? Link to comment Share on other sites More sharing options...
JustGav Posted September 27, 2007 Share Posted September 27, 2007 Have a word with Jezz, I'm sure he wouldn't mind let you know the sequence... Link to comment Share on other sites More sharing options...
jim_supra Posted September 27, 2007 Share Posted September 27, 2007 I did mine myself. Although I did it the other way to JustGav I lifted the engine and gearbox out throught the top. I did the conversion in a weekend with the car on axle stands. It's not too bad a job for those handy with the tools, it's just an involved one. I think Jezzybabes is in the middle of doing a write up on the entire swap which will be a great help to you. A little tip. If you are going to do it the way I did, make sure the engine crane has enough reach!! Also check and double check everything, it doesn't take much to miss something important, it may take longer but it's better safe than sorry. I highly recommend a copy of CJ's repair manuals to help you out while doing the swap. The NA 5 spd will bolt straight up to the TT engine, but as you probably know the 5spd is ok on stockk TT power but cannot take more power than that through it for long, or so I am led to beleive from discussions on here.

Yeah i think i will be fine with the mechanical side of it, but what is involved with the conversion with electrics? i know that a new tacho is needed (is this litterally just taking the old one out and putting a new one in?) and the ecu and harness. but what else?

Yes, the dial cluster from a TT is an easy swap job, the ecu harness is straight forward, although quite tricky to feed down through the firewall. One of the two connectors that go in to the fuse box will need swapping, but this is again a straight forward job, just take the one off the NA loom and connect it to the TT loom. easy! just make sure that it is done properly, as one of the wires is a feed for the starter motor, and the car will not start without it! Some people will say that you should swap over the entire fusebox instead, but this is just overkill IMO. Link to comment Share on other sites More sharing options...
miko_supra Posted September 27, 2007 Author Share Posted September 27, 2007 jim did you source all the parts yourself? or did someone supply you with the whole lot? Link to comment Share on other sites More sharing options...
jim_supra Posted September 27, 2007 Share Posted September 27, 2007 jim did you source all the parts yourself? or did someone supply you with the whole lot? I got the engine (really low miles) gearbox, and all other parts from Jezzybabes. Link to comment Share on other sites More sharing options...
miko_supra Posted September 27, 2007 Author Share Posted September 27, 2007 so does it matter at all if the engine you get was originally mated with an autobox, im going to mate it to a 5 spd? Link to comment Share on other sites More sharing options...
jim_supra Posted September 27, 2007 Share Posted September 27, 2007 It doesn't matter no. However you may need to change the flywheel, i'm not really sure about that though, I never really looked into this side of things as I decided I was sticking with auto.

miko_supra Posted September 27, 2007 Author Share Posted September 27, 2007 yeah, apparently you need the w58 (think thats the 5 spd box) fly wheel off of the GE engine. just gnna do this hopefully, then a few mnths down the line save up for a 6 spd.

NeoFuture Posted September 27, 2007 Share Posted September 27, 2007 if i have a NA and put a 6 speed box on it (got the XLS part list thanks for that) if i change the block for a TT will i need to do the box again or are the boxes interchangable ?

miko_supra Posted September 27, 2007 Author Share Posted September 27, 2007 6 speed will fit straight onto the tt Link to comment Share on other sites More sharing options...
miko_supra Posted September 28, 2007 Author Share Posted September 28, 2007 ok ive decided im going to go for this now, hopefully going to get it all sorted through jez in the next couple of weeks.
