ok, run into a little problem here:

the new V6 gear box has male guide pins (2) whereas the old V4 box has the receiving holes. so now i have the guide pins sticking out of the engine and the new box.

(edit) or are these pins just 'stuck' in the gbox from the donor engine??

What do i do? can i tap out the guide pins from the new box? pics soon so u can see what im talking about

Ideally, you tap the dowels in the gearbox out. Now,when you do this you need to get a dremel or very fine sandpaper in there and polish the chamfered edge back to be super-smooth. Any burring or scratches on that will stop the box from going together. You want to do the same to the pins in the motor, making them ABSOLUTELY smooth. Get a set of cheap vernier calipers from Bunnings and measure the dowel to make sure it is MAX. 10mm diam.

and here are the brakes, they have quiet a bit of rust on them, espesially the rears in the handbrake assembly.
My plan is to spray the shit out of the inside with rust killer/converter to rid it of all that flakey shit? sound good? any suggestions

That's how most import brakes come. Spray the bejeesus out of it with Inox and clean them up with a metal scourer/light sandpaper. Once you've done that, give it a prime and rattle can black.

Surface rust is nothing to worry about.

spent this arvo cleaning up 1 front and 1 rear brake, there starting to look respectable. had a mate come over so we had another futile attempt to fully install this stupid gearbox, but ran into yet more problems. seeing as this RA box is larger than the old im having issues with clearance from the dumpipe/turbo my just millimetres. nevertheless i believe the turbo must be removed, but looks like a major pain in the arse.

so, my questions are:
  • has anyone run into the same problem upgrading boxes?
  • is there an easyway to remove turbo/pipe setup? (apart from disconnecting oil, coolant lines and 50bolts
btw already rounded one of the turbo/dump pipe nuts so not happy jan!

Physically the boxes are the same size, so it's more than likely an alignment issue.
Easy way........Ha!

There is no easy way to remove the turbo and up-pipe. You'll most likely also have to drop the headers off the bottom of the motor to give you more space.

Frank is right in that the 5MT cases are the same size. There is no difference there - you must have it aligned incorrectly.

For turbo/dump pipe nuts/bolts you NEED to make 110% sure that the spanner (and a good quality spanner/etc) is definitely seated on the object you're trying to turn before cranking it. I also find I need hex-sided sockets, rather than the normal 12-pointed socket. I also use Crows Feet tools as they grip much harder. Another option is to hammer a 1mm smaller socket onto the nut to get it to turn. You'll need to replace this one when you get it off, though.

Hex vs 12-point

Had a similar problem just recently with a rounded nut on the dump pipe...what a freakin nightmare. We attacked it with a hacksaw, cold chisel, hammer, and eventually a dremel to get it off. Depending on which nut it is and how much room you've got you might be able to get one of these bad boys in there, you hammer them on then put a large socket over it to undo it:

hi..

your issue will be the intermediate bolt hole near the turbo. youll have to grind some metal off to make it fit, happens with most 8 bolt boxes into 4 bolt cars..( 4 bolt boxes dont have this section, its flat with no bolt hole)

just hit it with a flapper whieel on an angle grinder and take 2-3mm metal off the entire corner along the length of the bolt hole..

wont compromise the bell housing strength..

btw, this will not need removal of the turbo to do.. just the box out again


wtf?

here we go again.

Or you can use 3/8 drive socket utensil's

Or metrinch spanners and sockets.

this morning when i looked at the gearbox i wussed out and decided NOT to shave the gbox for clearance. instead i bit the bullet and decied to take the turbo off, turns out the dump pipe had to be removed and the turbo LOOSENED just enuf for a few mm play, which meant i didnt have to diconnect any lines/hoses or headers :D


the whole bolt came out of the turbo.shows how stuck on the nut was ay...

nice little set up so far mate all seems very similar in my garage at the moment, there is always something that will go in twice or if ur really lucky three times thats when u know ur an unqualified genius looking at the bolts u just did up thinking hmmm better get those little fellas off again.

u probably all know this but just in case.....especially with exhaust or brake lines you should give the nut a little crack in the clockwise direction ensuring the tool ur using is secured on the nut properly first of course, in most cases that will save u many a nut or bolt rounding.

marv....i am impressed with the look of the parra coloured weapons. what are they? are they irwin item?

good luck with the loom on the dccd and the rest of the build. well done on those braids.
