Td05 20g Fitting


Recommended Posts

I'm far from technical but had a go at removing my 20G. Got stuck with the last bolt on the underside of the downpipe. My not very extensive toolbox didn't help but it is possible albeit a bit tight.

Once the downpipe is out the way i've been told the uppipe becomes a little easier but theres still a couple of PITA bolts on that too.

5 bolts i believe for the up and downpipes

I done my own on a classic,Other than dodgy bolts the most awkward job if you are doing it on your own is getting the turbo in position with the oil return pipe best done with assistance.If the bolts and studs are refusing to budge you can grind off the two on the bracket and remove with the uppipe still attached which i found easier.I have also heard that on a six speed a part of the bellhousing needs ground but havent done that Hope this helps.Gary

You may also have to grind a slight bit on the block to accomodate the water pipe on the inboard side of the turbo I did. I also had to modify the actuator bracket slightly as this fouled on my AN right angle fuel connecter at the no.3 cylinder. Other than that it should be a straight fit. :lol:

TY754 boxes (MY98-) and TY756 (6-speed) boxes need the removal of a peice of the box where on of the mounting bolts for the box goes in. Use a Chisel and Hammer as its easier.... If it comes with the Newage Coolant pipework, there aren't any fitment issues there.

Just make sure all holes (uppipe, Oil return, etc) are fully covered up before removing the peice of the box as you don't want metal, etc getting in there.

5 bolts for D/P to Turbo, 3 bolts for Turbo to U/P.

ps - if it is an with the old style housing on the 20g (polished flat area on the Compressor housing on the top right as you look at the Compresssor housing face-on). then chances are it is a large oulet nipple on the Compressor wheel for the Boost control. Make sure you fit the vacuum hose (make it 40cm as a precaution) BEFORE fitting the turbo as it is harder to install afterwards.

Russel I am using a TY754 box at the minute and had no clearance issues, may be down the make of up-pipe fitted :thumbup:

If you got a NEW 20G then Andy (AFAIK) grinds down the area on the Turbo the makes contact so it'll already have been done for you B)

I've had issues with 20g's using OE uppipe and aftermarket (GT Spec and H&S) uppipe in the past so may not necessarily be that but thatks for the info :)
