Heat Shield Over Turbo

Is there any cons to not having a heat shield over your turbo on a R33 Skyline? as I am thinking of leaving it off...

My cousin runs his without it, doesn't seem to have any problems. Just be careful there isn't any obstructing items/bits around the exhaust side of the turbo though, you don't want anything to burn.

The other small nuisance is everything around the turbo gets a lot hotter - when we were working under the bonnet (particularly on that side of the engine) after taking the car for a test drive, we'd just have to wait for things to cool down.

Basically you will just increase engine bay temperatures, which is a downside. Leave it on if you can.

Or if you really hate the look of it make one yourself that looks better - I did.

can we see the one you made? :)

what material did you use?

I used fairly thick stainless steel to try and isolate the heat. I also made it go down as far as possible down the side of the turbo.

Not the best picture but you get the idea.

Nice heatshield!

If the car sees hard work (track days, drift, burnouts), you really want to consider leaving the heatshield on or making a baller heatshield like Phil

Mate of mine had his car catch fire under the bonnet due to no heatshield after ripping a burnout at Powercruise.

Also in the drift cars with no shield you can sometimes see issues with the paint on the bonnet over the turbs

i'm thinking, as good as it looks, is stainless good as a heat shield though? doesnt it get crazy hot itself?

what about aluminium?

or this stuff? its very shapeable. ceramic sandwiched between aluminised steel sheets?

Yep that stuff above is a lot better as an insulator.

As regards to aluminium I don't think it would insulate heat any better and may start to melt or burn if fairly thin (from memory aluminium has a much, much lower melting point).

My setup is definetely not the best heatshield you can make, but easily noticable difference of under bonnet temps with it on or off (have had it on and off heaps of times in the past).

Like I said, mine was mainly for looks and to atleast have some sort of shielding in that area.

      Duncan's V37.......race car?

      By Duncan · Posted

      So, before putting them in I need to understand the stock ride height. This is how I measured it: First, check the diameter of the wheel's centre cap, it was 52mm. Then put a piece of masking tape approximately across the centre and measure 27mm (half) from at least 3 sides to get a reasonable idea of the centre of the wheel cap. Mark that with a horizontal line as one measuring point. Then, directly above the wheel on the guard, put another piece of masking tape in approximately the centre. Use a string line to find out the point on the guard above the centre of the wheel cap and mark that. Then it is simple, just a tape measure to check the distance from centre of the wheel to the centre of the guard. Final results where  LF: 381mm RF: 379mm LR: 401mm RR: 400mm Pretty even considering they are 120,000klm old factory springs, lets call that 380 front and 400 rear.

      So....knowing that I have a problem with power steering temps on track and another Wakefield day booked in next Friday, I've done the obvious thing They are very reasonably priced at $1650, considering they are a big monotube shock, double height adjustable (don't have to change pre-load to change ride height), one way adjustable damping and standard sized and customisable springs if you want something other than what comes with them. They come with 9kg/mm front and 4.5kg/mm front and I went with that as a starting point because I'll add adjustable sway bars too https://justjap.com/products/bc-racing-coilover-kit-ds-ds-infiniti-q50-v37-14-current#description Unfortunately they didn't come with rear strut tops so I've re-used the factory ones which was a bit of a pain. Also, the adjuster for the rear shock will be an absolute nightmare to get at, and while there are extensions in the kit I can't see any way you can actually attach or use them

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      By Duncan · Posted

      I also had 2 bulbs blow at once, years ago in the stagea. made for a fun drive home. The issue was the voltage regulator had failed in the alternator and it was giving 15+ volts. Really, I was lucky all that was fried were the headlight bulbs. So, I'd suggest you check the voltage across your battery terminals with the car running and warmed up. Yes, you will need a multimeter to do so, sorry.

      Good work to think to check that, and thanks for coming back to post up the outcome.

      98 R34GTT 4k engine stumble

      By Duncan · Posted

      Given it happened suddenly, and when you come on boost, I'd check all your inlet - hose clamps in place and no split rubber or silicone hoses. Even the hard to get to ones near the intercooler. It's possible air that went past the air flow meter is being dumped out a big hole.
