Quick Question Regarding Turbo Blanket & Heatshield

Hey guys

Just a quick question here. I got a new 3" turbo back exhaust installed, but like most people I have read on the forum, workshop didn't put the stock turbo heat shield back on when they installed the the exhaust. After some searching, most people are saying that the stock heat shield will fit regardless of what front/dump pipe is installed. So I'm going back there on saturday & see if they still got my heat shield along with my old exhaust bits & pieces, & I'll try & see if the heat shield will fit back on.

But just in case it doesn't or they have binned it, will some thing like this fit the stock turbo? If it doesn't what kind of turbo blanket should I be looking at?

I'm abit concerned for the plastic electrical bits & wires near the turbo, they get very hot after diriving the car for a while without any form of heat insulation around the turbo, don't want them to melt & cause a short or fire.

I have included a picture of the turbo & the pipe.

On a side note, why does my turbo look like a rusted bucket of crap, compared to the other parts of the engine?

While I was searching on the topic I came across another member's engine bay & his turbo is nice & shiny :blush:

Heat shield keeps the radiant heat from the surrounding and lets the heat get off the housing somewhat.

Now a turbo beanie is going to keep the heat in much more...

This brings up and interesting question of... will this aid in the death of the factory turbo? :blush:

IMO go the heat shield.

The Shield will definately fit so put that back on.

I read that turbo beanies on street cars arent ideal and can be a fire risk too.

I gave the stock heat shields a squirt with some flame proom black paint. Look great.

I did the Actuator too ha.

Quick update

I went to the shop today to get my old exhuast back from them & I got my heat shield back as well.

I have now put it on, looks all good now, no more rust bucket turbo in sight :D

On a related topic, should I heat wrap the dump pipe as well? Currently I can't be f*cked doing it (too lazy , seeing how theres no plastic or electircal cables near by that are in danger of melting. I read from here that is done with heat wraps tape thingys, but they tend to smell alot initially... & some one even mentioned white smoke coming from the heat wraps.

Which brings to my last thing that I would like to get some extra info on... currently my exhuast smells alot (its not petrol smell, I'm very familar with that smell, since I had a fuel line bursted b4 & the car pissed fuel all over the drive way... got a whole does of petorl smell back then :) ), I read from an old thread that this is caused by a layer of oil thats on the new exhuast & that it will burn initially until its all gone. Is that correct?

Seems like the smell has gone down somewhat compared to when I 1st got the car, which is a good sign I guess.

Thanks for all the help so far. :rofl:

Is the exhaust stainless or mild steel?

If its steel, sometimes they paint them with heat paint and that smells a bit for a few days till it cures with the heat.

And sometimes stainless does have a random oil on it and it smokes a bit the 1st few times too. Youl be all good!

      Well, if it wasn't a GTR I'd say that killing an RB is a perfect opportunity to put in a proper engine. In your case, proximity to Brabus and AMG V12s would be a no brainer for any RWD Skyline engine death event. In my case, because my car is my daily, anything that I do wrong that means I have to do it again is both an absolute pain in the arse (simply having to do it again), and also a doubling of the pain associated with having the car off the road to work on it. I would class a botched head gasket install as not being "engine death causing". More a case of "f**k it's still leaking!"

      Yeah, this is more stuff like transmission/clutch R&R. Intake manifold R&R. It's not super complicated, but each step matters and you need to be careful and patient. I have heard stories for example of people not figuring out the super coppermix twin plate orientation and getting it wrong on assembly. Removing a cylinder head and putting it back in once it's machined isn't that hard, following torque sequence to install some cams isn't that hard either, but somehow I've seen a lot go wrong between here and there. Scraping off all gasket material isn't that hard either, but I've seen shops ruin heads by using a roloc disk that was too aggressive.

      There is some shops in Germany that have quite a bit of experience with JDM performance 4-wheelers. I think if it actually comes down to it I'd let one of them do the head gasket. Killing an RB26 is too expensive a risk just to save some money by doing it yourself.

      There are certain tasks, like replacing head gaskets, where it is very much best to already know what you are doing, and if you are not already an expert, then the next best thing is to have an expert around to help it get done. Little annoying checks and steps that are easy to forget or not interpret the results of properly, etc etc. It is hard to convey that to someone as a lesson prior to taking on a job, because there can be a whole list of "if you see this then it means that", or "if this is what you find then you will need to do these other 4 steps first". All the little bits of knowledge around sealant choice (ie, sealant at all? or no sealant? sealant only in certain parts of the gasket? sealant for this type of gasket but not that type of gasket? etc etc) cleanliness checks and methods, surface straightness and finish checks and methods, etc etc, all combine to mean that people who have done many of the same type of job will struggle less to get a good result than someone who hasn't done it before. I've been around this stuff since forever. But I will still consult with my expert(s) before taking on the big stuff with higher risk profile.

      Well if I end up having to do the head gasket I will certainly find the necessary tools and instructions before beginning... Let's hope it won't come around.   Definitely. Depends on the job but I think "if you want it done right, do it yourself" applies almost every time
