Dump pipe removal

[Chris32]

Hey guys,

Swapping dump pipes on my car this weekend, anything I should be cautious of when doing this?

Any tips on how to make it easier etc

regards, Chris

Easy job to do on a 33 is all i can say.What dump pipe have you got for it?

[yogi000]

make sure its cool.......soak it in wd-40 or something similar......and a short and long handle spanner....not really necessary but makes life easier.

cheers

I have two to try, one is a HKS style split dump pipe, and the other is a dump/front pipe in one of a mates R33, judging by whats for sale in the shops the 33 and 32 front/dump pipes you can buy fir both no probs

Hoping to try both out

[Chris32]

Will be doing it cold, first thing in the morning I hope

Plan is to removal the exhaust manifold heat shield etc and un-bolt it and bolt the other one up, hopefully

...and done it for you.

Long extension and undo three nuts (dump-front pipe) it should sit after dropping a bit if all OEM bkts are there.

10mm 1/4 drive and undo the bolts in the small turbo shield... unplug o2 sensor. 10mm ringy for the sheild bolts down near shock tower. These are brittle and may break (Clean thread and use copper eze when replacing)

Undo stubbie... think about it for a while.

No dramas really

TT

PS Did you say you had some spades that fit the ecu plug off a wreck? Need a couple.

Mine went snappy snappy:(.... so i suppose WD40 is your friend

any1 has an idea which cable is the oxigen sensor.....rb25det has 3..... but im not sure which one to connet the air/fuel gauge cable to???? any help?

[MacGuyver]

When I got a new dump pipe along with my exhaust, all the bolts joining the turbo to the dump pipe snapped and cost me about $250 to replace them! Poor value!

[WazR32GTSt]

my dad and i snapped a bolt going into the back off the turbo

be VERY careful especially when using a ratchet...

[Fazt_R33]

it is essential to have the car on a hoist to get to the turbo bolts? or can i jack it up or park it upcurve to get to the cat and turbo bolts?

[Skyrine-Dave]

a few days before i took mine off i started to spray WD-40 on ALL the bolts, even the heatshield

just give them a nice squirt over the next few days and you should be right

[Chris32]

Dump pipe came of no probs, made sure I gave the bolts a good soak and didn't snap anything!

Problem was the two dump pipes had differant exhaust stud pattern, so it all came off ok............and had to go back on

3.5" dump next week, funnily enough, my car is making 205rwkw with a 2.5"dump and front pipe...........and a pair of 2" gaskets on the cat...........dodgy!!

Just by replacing the gaskets saw boost jump up a bit, so hopefully with a 3.5" dump, there is a few more kw's to be had

Cheers for all the help/suggestions guys

Has anyone ever had a problem with the stud bolt snapping off in the turbo when removing the dump pipe?

I'm going to be changing my dump pipe this weekend. I would really like to know if I have to prepare myself for the painfull process of removing broken stud bolts.

The car is a 95 GTST,

Replys would be greatly appreciated, so if you have done it could you post up what happened either way.

Cheers,

Yeh it happens alot, just be carefull and try not to yank at it too much

If it happens it happens, not much u can do

[Fazt_R33]

:whackit:

wooho.... goddamn is hot...

i jst replace ma dumpipe & frontpie....

the secret to NOT snapping the bolts is to tighten the bolts jst a tiny bit, sot that the locked treads unlock.... then undo the bolts with patients....shouldnt be to hard....

but dont make the mistake i made... make sure to put the turbo heat-shield back on.... it realy makes a dif temp wise in the bay...

if your gaskets, either turbo gasket or cat gasket are Copper gaskets, use these instead of the cheapo silver paper thingies.....

i beta get bak to undoin ma pipes to put heat-shield back on.......

[josh303]

the best stuff to spray on the rusted corroded bolts is, 'rost off plus' it's made by worth, im a truck mechanic and we have found it's the best thing for turbo and exhaust manifold bolts. it's not cheap but quality comes at a price..

cos dont we all hate drilling out broken bolts.

[Tonkotsu Flavour]

Can you reuse the gasket from the dump pipe inlet and dump pipe outlet?

or does anyone know the nissan part numbers for these gaskets?

[craz0]

I just threaded one bolt and snapped another know I have to take the turbo if so I can easy out the little bit of nut left in there.
