First time fitting of turbo.

[Abo Bob]

Hi all.

I am fitting my high flowed turbo this weekend. I took it off myself with a couple of hassles.

One bolt holding the dump onto the exhaust housing broke off and one was a hex head (allen key) bolt which required an allen key fitting for the socket set as an allen key itself didn't have enough room to swing.

Anyway, should I, could I replace the allen key bolt with a normal one or is there some reason for it being there that I can't see?

The replacement bolt for the one I twisted off, is it special?

Do I use locktite or anything like that anywhere, like the turbo to manifold bolts or the dump pipe to turbo exhaust housing bolts?

I lost a couple of the copper washers from the oil lines and water lines. I've been told that these things compress and that I should get all new ones anyway. Should I?

There seems to be two on each bolt right?

Who sells these? I've tried Auto1, Bunnings and GCG with no luck so far.

Am I alright to reuse the gaskets? They look ok. The turbo to manifold one is fairly new anyway cos I spat it about 6 months ago.

Should I be cleaning any parts out in any particular way while things are apart? When the stock turbo blew plenty of oil got burnt. Does any part of the exhaust need cleaning? It's all sort of brown on the inside instead of black.

And finally, while I have your attention, I noticed how easy it was to get the exhaust off. If I got a side pipe to replace the cat and cat back sections of the exhaust for track days, would it effect the tune and cause me problems or do you think I would get a few extra kilowatts out of it?

Thanks.

Hi all.

Anyway' date=' should I, could I replace the allen key bolt with a normal one or is there some reason for it being there that I can't see?[/quote']

it's most likely that someone has previously broken/rounded/lost one and replaced it with the hex bolt thinking it would be easier to get off. you can replace it with a normal one no worries.

The replacement bolt for the one I twisted off' date=' is it special?[/quote']

just take one of the other good bolts in when you go to buy the new ones and have them match it up

Do I use locktite or anything like that anywhere' date=' like the turbo to manifold bolts or the dump pipe to turbo exhaust housing bolts?[/quote']

the ones that i've seen come loose are the tubo to manifold ones, generally there should be a little plate with locking tabs that you fold up to stop them coming un done but sometimes this plate is gone, and even with it they can still come un-done. a little locktite here wouldn't go astray.

I lost a couple of the copper washers from the oil lines and water lines. I've been told that these things compress and that I should get all new ones anyway. Should I?

I would they don't cost fark all. especially for the oil and water lines.

for any banjo bolt there will be two copper washers.

Who sells these? I've tried Auto1' date=' Bunnings and GCG with no luck so far.[/quote']

Lee brothers in para' date=' or coventry fasteners or earls in silverwater (won't have the bolts but will have washers)

Am I alright to reuse the gaskets? They look ok. The turbo to manifold one is fairly new anyway cos I spat it about 6 months ago.

up to you. If they are not to expensive I would just get new ones. is the manifold still on the head? or did you take turbo and mani off together? the head to mani one is expensive the others are not too bad.

And finally' date=' while I have your attention, I noticed how easy it was to get the exhaust off. If I got a side pipe to replace the cat and cat back sections of the exhaust for track days, would it effect the tune and cause me problems or do you think I would get a few extra kilowatts out of it?

it shouldn't affect the tune to badly, but a run on the dyno with it on wouldn't be a bad idea. dunno if you would get any power but as you know I have had one planned for mine for a while. steal my plan you bastid.

[benm]

I'm interested to see the before/after power

GCG should be able so sell you all the bits - if not, try UAS they usually stock these.

Get new gaskets - you can damage them when removing them - do it once , do it right. I tried to re-use the oil return gasket and I got a leak and had to do it all over again.

Use copper grease - not locktite

Yes replace the copper washers

Re Cat - no won't affect the tune and will give you substantially more power - trust me on that, but don't ask me how I know.

Have you got better front and dump pipes ?? eg CES Racing systems - these will make a big difference too.

Good luck with it.

Cheers,

PS - Can you pm my docket again please ? Farking idiot me lost it again ! Thanks,

Bolt Master in Penrith or

Coventry Fasteners in Artarmon will have those bits and pieces.

man pay someone to do it would be like 150 bux

[Abo Bob]

Thanks guys.

I have already tried coventry. No go. Repco says they have the washers so I'll go there. They should have the bolts too wouldn't you think?

I have a CES split dump/front pipe combo.

I couldn't believe GCG didn't have the washers!

I didn't take the manifold off. Turbo came off it easily despite several people warning me I would have to take the manifold off to get the turbo off.

Oil return gasket? Is that the one on the bottom of the turbo?

I've got the locking plate for the turbo to manifold bolts so no worries there.

I will try to fit in a dyno run without the cat back to test this theory for sure.

Of course I'll post up results Ben I'll be like, "Look I got 5 rwkw from a turbo upgrade" (Best to talk it down to avoid disapointment)

Was quoted $600 remove and replace. Get more satisfaction out of doing myself anyway. Also, it's already in pieces in my garage which is down a very steep slope so no tow truck is getting in there.

yeah coventry don't really specialise in automotive stuff. Lee brothers (which I posted above) will be your best bet. they are in parra.

good man getting it off without removing the mani cause that gasket is another $50+ alone.

600 nasty

give us a bell im sure we can sort it mate
