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

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 :D

...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.

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 :P

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,

: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....... :)

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.

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
