safcdixon Posted November 10, 2017 Share Posted November 10, 2017 Quick intro to this project, bought an Na auto from an old mate that needed it gone quickly, it wasnt running mot had run out etc etc, bought as a side project whilst i build my single turbo on my black car. overall the supra looked rough on the surface but overall solid (except the bootlid, usual spot) stripped some of the car down and sent it to the bodyshop, i hadnt removed the sidepods at this point. reason im posting this is to alert current and potential owners to the hidden rust problems on these cars now, and even if you treat the car well give under the skirts a check over ever so often, pics below of when i collected it and of the rot.

safcdixon Posted November 10, 2017 Author Share Posted November 10, 2017 Also floors, chassis mounts etc are all good aswell hence the shock on finding the above rot hidden under the sidepods Quote Link to comment Share on other sites More sharing options...
Scooter Posted November 10, 2017 Share Posted November 10, 2017 When a similar age of cars 'under the rear hockey stick' can look like the attached, you have to wonder how the rust started on that one to get so severe? Quote Link to comment Share on other sites More sharing options...
evinX Posted November 10, 2017 Share Posted November 10, 2017 Its happening on a lot of them now. Scrapes and chips lead to thos stuff. When i first got mine and was doing touch ups i noticed bits starting and quickly sorted it. Quote Link to comment Share on other sites More sharing options...

Yeah the other three supras i have are all clean and rust free in the same areas that this one has serious rust, bit of an odd one. Its happening on a lot of them now. Scrapes and chips lead to thos stuff. When i first got mine and was doing touch ups i noticed bits starting and quickly sorted it. Think this is probably the cause this car had a repaint (very badly it seems) about 4/5yrs ago could well be the cause, it has 200k onit aswell which wont have helped Quote Link to comment Share on other sites More sharing options...

Epoxys do. Probably could be it Quote Link to comment Share on other sites More sharing options...
mc92 Posted November 10, 2017 Share Posted November 10, 2017 Mine was mangled underneath from some idiot jacking it up improperly (including on the floor) and I had some nice rust holes at the back of the pinch welds which I've since had welded up. It's also got bubbles around the windscreen and on the sills below the doors so it's back to the bodyshop again soon. I don't know if there's some issue with the paint or if it's just an old car being old but after everyone on here goes on about how rust-free their supras are I'm jealous. Best to check behind all the trim and get it fixed asap for sure. Quote Link to comment Share on other sites More sharing options...
jonc Posted November 11, 2017 Share Posted November 11, 2017 Wow!! I have never seen a Sup that bad anywhere. Where has it been parked in the sea? Areas I have seen or heard off Front cross member under the radiator Plenum in front of the windscreen where the wiper motor sits Tailgate around glass. Probably the most talked about area Fuel tank guards Rear bumper beam And underneath Floorpan to sill where idiots jack the cars incorrectly Under the rear quarter fwd of the rear wheels. Other long term members may have seen other areas as well but that NA is not indicative of MKIVs I have seen Quote Link to comment Share on other sites More sharing options...

supraGZaerotop Posted November 11, 2017 Share Posted November 11, 2017 (edited) got me worring now. i should really take my skirts off and take alook. my skirts have been loose along the door sill for 10 years. do the skirts remove easily without damage? if so how do tjey come off Edited November 11, 2017 by supraGZaerotop (see edit history) Quote Link to comment Share on other sites More sharing options...
evinX Posted November 11, 2017 Share Posted November 11, 2017 got me worring now. i should really take my skirts off and take alook. my skirts have been loose along the door sill for 10 years. do the skirts remove easily without damage? if so how do tjey come off Check the bottom of the doors. They tend to rub on the oem skirts. Screws 10mm at the bottom. 3 screws on the front. 2 or 3 black pop grommets on the rear. Careful when pulling off. May need a metal ruler to release the double sided tape along the top sill. A screwdriver is too thick and will crack the thin plastic Quote Link to comment Share on other sites More sharing options...

jonc Posted November 13, 2017 Share Posted November 13, 2017 Fair one mate. Maybe a sticky on known areas to corrode should be put into the members area. These cars are heading towards 25 years old soon so the tin worm is bound to be an issue sooner or later as are the mechanical Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted November 13, 2017 Share Posted November 13, 2017 It's also got bubbles around the windscreen all around the windscreen and rear window seems to be a common area on these cars, one I saw a few years ago had only just come from japan and the drivers A pillar had almost rotted completely through. Think they did a poor job on the paint around the glass. Another couple of places worth checking are under the windscreen scuttle, and on the roof of the shell, in the recess where the rear hatch hinges are. I've seen many of them have surface rust here, which will turn nasty if not sorted. Quote Link to comment Share on other sites More sharing options...
phobos Posted November 14, 2017 Share Posted November 14, 2017 all around the windscreen and rear window seems to be a common area on these cars, one I saw a few years ago had only just come from japan and the drivers A pillar had almost rotted completely through. Think they did a poor job on the paint around the glass. Never seen that before. Could also be caused by a poorly performed windshield replacement, when the paint was damaged. and on the roof of the shell, in the recess where the rear hatch hinges are. I've seen many of them have surface rust here, which will turn nasty if not sorted. Absolutely agree on that one. My Supra is straight from Japan and had no rust, except for a few very minor surface rust spots in that area, as well as some spot welds with surface rust on the vehicle underbody.

mc92 Posted November 14, 2017 Share Posted November 14, 2017 I think on mine it's because the windscreen seal is old and water can get in behind it and sit there. Quote Link to comment Share on other sites More sharing options...
safcdixon Posted November 14, 2017 Author Share Posted November 14, 2017 Proper Shit heap Marc lmao your turning into the North East Keron Its looking pretty decent now tbf, just thought this was worth posting for the less ocd owners (like you) to check these areas just incase Quote Link to comment Share on other sites More sharing options...
MattP Posted November 14, 2017 Share Posted November 14, 2017 Most imports I have seen have surface rust on the roof hidden by the boot lid at the top and under the scuttle panel if you look through the little gills on the top next to the wipers. other than that its generically examples that have been in the UK for a while not garaged and generally driven and left that suffer.
