AH! it's finally showing up! I've been waiting for weeks to see the updates...

That is one fantastic GTS25T!
May I ask to either Matt or Bob, or maybe some other mechanics, what is the goal of this project? Is it a restoration or "amplification" project? :)

Hi Leonov34, the goal here is to restore the car to "show quality" and convert the body shell to look like the GTR but it will have the added bonus of rock solid rust protection. The engine bay should be gleaming when it's done too.

Hi Matt! How are you? :wavey:

I see, I reckon this project will turn out greatly! your car is surprisingly sexy, I can't imagine what it is going to be later :runaway:

With the engine, gearbox and front suspension assembly out it was time to turn to the rear suspension.
Matt is having a full strip, zinc coat, powder coat and poly bush with SuperPro and Whiteline suspension bushes so it all has to come out.
It's gonna handle like its on rails when its done!:bowdown1:





Rear subframe assembly, a few subtle differences but basically all Skyline models share a very similar layout.




Then begins the job of stripping all of the suspension arms out, rear handbrake mechs, driveshafts, diff, hicas etc etc.....


Here are the rear hub components stripped down and ready to take the bushes out.





The GTSt has steal hub carriers unlike the GTR, theyre in pretty good condition like the rest of the car. Unbelievably this car hasn't been garaged since Matt's owned it.

Rear subframe in its bare form, now starts the 'lovely' job of burning out and cutting out all of the old bushes.:runaway:
:D





With the subframe off we dropped the fuel tank, being careful of all of the fuel lines and filler hoses as we dropped her.
The tanks on 33's are big old things so its a two man job esp when there's fuel in the tank.





So we now have a nice bare chassis to work with.




Inspection of the front wheel arches and suspension mounting point showed up some isolated areas of rust. (to be expected on a car of this age really).





Here we can see in close up the areas mentioned.














The rust might look bad at first glimpse but actually the fact this car was not undersealed is a saving grace. :bowdown1:
The air has continually been allowed to dry out any moisture that may have built up.
Underseal seems to degrade over time and then flake and trap moisture between itself and the metal. :mad:
It always creates a worse resulting rust from what we've seen of these cars over the years.
Needless to say all of the above will be taken right back to bare metal, treated, cut out,
repaired and then sealed properly with a 2 pack Epoxy Resin.
Treat and forget!:wavey:

Weirdly the passengers side wasn't as bad as the drivers side which is unusual as this is the side that is exposed to all of the environmental stuff
that gets chucked up from the side of the road.




to be continued.....

Cheers buddy! :D
But believe you me, there's nothing lowly about this car!:cool:
:thumbsup:
So back to the pics of the work in progress on Matt's 33.
We started the messy and long job of stripping back the front arches back to bare metal, removing all surface rust and helping to reveal any more
serious issues corrosion wise.




Looks super clean back to bright metal.




This process helps to reveal clearly the areas that need attention, as said previously it's usually
between panels where the seam sealer traps the water and expands the gaps between the panels.








A more indepth clean up of these area, taking all of the seam sealer out from between the joints to be able to assess
the damage and what needs replacing with new metal.





Cutting out the bad stuff is only way to make it good!





There's no other way of clearing out all of the rust that hides between these adjoining panels.








The badly rusted metal sections were cut out, then new panels fabricated and then welded in their place.





Other sections where the rust had set in were cut out to be repaired, (being careful to maintain the structural strength of the arch and for good measure brace the strut towers too.









Cleaning up even the lightest of surface rust that gets revealed as we go along.





Here you can see we now have full access to the interior of the rusted panels.
Matt's car is very solid but when were done it will be 100% solid:wavey:
Ready for clean up!:clap:





Much better!:cool:





More fabrication work to replace sections as we work our way through the passenger side strut tower.





And now with all of these panels allowing us full access, it was time to remove the strut top itself.
We could tell by looking at the rust on the surface that had started to swell and break though on the strut top, that it would be rusty inside.
It's so easy to patch up or ignore this sort of corrosion and hope it won't get worse but when you see how bad it can be between the two layers
the only course of action is to get in and fix it once and for all!:wavey:


All of the spot weld drilled out and the panel cut either side to allow it to be removed.





And this is what you get inside.




Fossilised metal.:runaway:







So we first remove the heavy stuff. It actually chips off quite easily.








Then spend a few hours and various methods getting what you saw back to bright shiny metal. Then leave over night with a deep rust treatment.





To then be cleaned back to shiny bright metal again to make sure the metal is totally rust free and clean to make a perfect repair.

Another new panel fabricated and welded in.



You can see in the top of the panel above on the side of the strut tower there is a rusty hole that has started to appear,
again another area where the panels are joined and the rust has just sat and developed.

So we cut this rusty section out.




You can see the panel the other side of which has rusted through to the previous panal. So repair to both panels will make them good as gold.
(no point just covering up this stuff, do it once do it right! :thumbsup:)





Meanwhile Matt had provided us with donor strut towers from another 33 to help with the repairs.
They were in much better condition than his own strut towers but we could see they wouldn't be perfect inside.


Jay going about drilling out the spot welds and removing the donor strut top and thankfully it looked better than the one that had come off Matt's car.




Meanwhile......
The rust treatment on the car was doing a lovely job.




Back to the donor struts and this is what we revealed.




They look bad but were a lot, lot better than the ones we would be replacing.


A deep clean up of the donor strut to back to shiny bare metal, was defo worth replacing with.:wavey:



These will. once cleaned up make the strut top repairs perfect!:clap:
:thumbsup:




To be continued....much more to come.....
:thumbsup:

Oh I know Ive had 2 GTST's and loved them both but usually its the GTR boys that have the wonga for this kind of work.

I can see why a strut top repair could cost quite a few pounds! So much work.

Ok so as before the work continues on Matt's 33.
:)

The repairs on the passengers side continues, the lower section where the strut top meets the chassis leg had signs of rust gathering between the panel seams.



Nothing for it but to cut out the bad stuff and repair with new metal.



We had to cut the outer panel to gain access to the inner and vice versa.
You can see here how much the rust has spread between the panels,
left untouched this would just have continued to spread and get worse.







New metal was templated off the rusted section and tack welded in to make sure the fit was good first.





Then welded in place to make good.








With the outer section in place and supporting the inner section we cut out the rusted inner layers to replace with good clean panels.




Then with the inner repairs made we buzzed up the outer to make the panel complete.




Back to the work on the all important strut tops.:runaway: We stripped the donor strut top back to bare metal,
treated with an acid that draws out all of the rust from the metal and leaves a layer of protection while were working on the rest of the panel.




The main strut, all spotlessly clean, repaired and ready to be protected prior to refitting the strut top.



Such a contrast to how we found it.
:wavey:

The two halves of the puzzle trimmed for a perfect fit.




A good layer of zinc rich primer for proper long lasting protection in the future.
:bowdown1:





Why oh why Mr Nissan didn't you do this properly from the factory?:confused:


Plug/seam welded back in place, fit is perfect!





Clean up of the welds to make panel look like factory again.




The rusted out front section was fabricated and welded in place to complete the strut top. (this section always seems to go right at the front of the strut).





All cleaned up and protected whilst we move on to the rest of the work.
:cool:





Clean up of the surrounding area around the top of the inner wing top, inside of this panel was pretty good and solid so we cleaned it all up to clean metal and naturally protected this area of course.








Cleaned up and ready to reinstate the top panels where the GTR front wings mount ontop of.





once we get to paint we'll add the seam sealer to the panel seams to give it the factory fresh look.:thumbsup:





Another hidden section we had to deal with while the engine was out and we had great access to, (had to take out the wiper motor too to get full access here).





Cut out the bad.




Revealing this








New layered panels fabricated and welded in to replace all signs of rust.





More areas that were starting to suffer from the old tin worm, (luckily mostly light to medium rust levels throughout).





So we set about stripping out the rest of the ancillaries in the engine bay to gain access to these and the panels that need sorted on the drivers side.







Super model diet! :chuckle:








Drivers side strut to looks slightly worse than the passengers side which you wouldn't really expect on a rhd car.




You can see in the above pics areas that are starting to show signs of rust, all seam to be common areas on 33's.

Final sections of the inner arches in the camber arm mounting areas to be addressed too.








Sorted!:wavey:
Now for the other side. again it's a good thing this car wasn't undersealed (badly) in the past,
as due to this it was allowed to dry out in between getting wet, water wasn't allowed to just sit there and create traps for corrosion between the body and the underseal.





You can already see there's going to be some interesting stuff going on here too!^^^^:eek:


So the job of striping back to shiny metal begins to reveal the true extent of what we're dealing with.







Similar to the other side, in some cases slightly worse signs of rust, but all very fixable.
:cool:










Coming along very nicely:)

Will, next time your round buddy I can get jay to knock you one up mate!
