Hey guys,

Got my exhaust today and I must say I can notice a difference. Anyway I was driving just now and noticed a 'clank' every time i turned or wiggled the steering wheel. Popped the bonnet and noticed they had not put back the heatshield for the turbo.

Turns out the clanking noise was because they had left a tool adapter sitting in my engine bay, so im glad that was nothing, but I have concerns over if i should even drive the car without the shield, as there are wires and stuff that run closeish to it, and upon feeling them they were very warm.

Im just worried that ill melt something. But then again maybe they left it off because it wasnt needed?

So it won't melt any intercooler lines or wires that run near it etc? Thats a relief.

well depends whats "close" to it...

each car is different, some have wires changed etc.

IMO leave it on there, no reason not to have it, and it will reduce under bonnet temps

Roy had a heater hose close to the turbo dump perish and then popped at the track onto the turbo. Ethylene glycol, the fluid in most radiator additives flashes at 120 deg C so after the water steams off it burns with a thick black smoke.

You should have a shield.

2 track days without the turbo heat shield...

1st track day; nearly melted my oil catch can hose as it was dangling about 5cm from the turbo/dump pipe

2nd track day; re-ran the hose away from the turbo (now 10-15cm away) no issues.

I've heard it's good to keep it on, but not 100% important if your lines/wires are run currectly. Only other issue is the ABS unit, it doesn't like heat :)

Definitly have it on. A guy at the Z-Tune track day didnt have one one his S15 and the wires caught fire mid lap. The heat shield not only shield heat but acts a mounting point for a whole binch of wires (02 sensor i think). Unless you secure these wires some other way away from the turbo then the wires dangle dangerously close to the turbo.

In summary...there is no gain in having it off.

      Mistakes were made, my R34 Story

      In a few years from now, you'll regret that. It'll eat away at you, knowing the truth of the ugly hiding beneath the beautiful exterior... 😛

      I don't think the G2 profile is particularly dangerous for the engine per se, more just are you actually ok with the turbo lag trade-offs? If the answer is yes then go for it. I personally don't think I'd be ok with it because I spend so much time at lower RPMs and I really enjoy the feeling of being able to stay in 5th gear on the highway and just roll into the throttle to get boost. Or staying in 3rd gear on "gentle canyon cruises" without feeling the turbo lag too badly. The 525 pump should be able to run flat out on factory lines but I would bet the pressure drop from pump to regulator is quite impressive. I don't know how much it would be exactly but I've seen figures like 30 psi thrown around.

      It's interesting seeing everyone talk about what level of risk they are happy to tolerate.  Building a GTR always has a level of risk, you could be that lucky guy that drops 20k on the engine build alone and still has the thing go pop on the dyno. Life is fun like that.  The way I see it, the thing is a toy to be enjoyed. I'd be happy to turn up the power on stock motor and limit the risk with sensible tuning and engine protection. If it still goes pop, it is what it is. The car isn't a daily driver so it can happily sit while a plan is made to sort it out.  Given this thing will be a street car only, I really feel it's worth the (relatively small if managed well) risk to turn the power up to around 350KW on e85.  I don't think anyone getting into the skyline game now is doing it out of logic. Surely it is a purely emotional decision so I'm not sure how important it is to think about the engine build logically. The heart wants what it wants.  @joshuaho96 little note for Josh, I run my 525 pump flat out all the time and through the factory lines without any issues. (excluding the melting connectors, that's sorted now. we'll pretend it never happened lol)

      But the Nexus S3 is very expensive and won't be as purpose-built for the application as a separate electronic boost controller :^) More seriously my pet issue here would be that the Walbro 525 running at 100% duty cycle is going to require more FPR than the stock setup can handle. I'm also pretty sure from what I've seen elsewhere you might want to slow down the pump regardless unless you're going to come up with some way of upsizing the fuel lines coming from the fuel tank. Factory 8mm fuel line doesn't actually flow very much if you want to keep pressure drop down between the fuel pump outlet and FPR. If you really want to "keep it simple" I would run only as much pump as you need and source a fuel pump controller to slow down the pump in the vain hope of being able to run stock-style FPRs which are pretty dinky. Or just use the HICAS lines and it should be mostly fine. OP should also really think hard about what profile they'd want out of the turbo. My pet choice here would be the G1 profile rather than anything higher power but YMMV. I already think ~stock turbo lag is pretty bad so I don't want to make it worse. In "gentle canyon cruising" I found that I spent a lot of time around 4-4.5k RPM. I also recommend DIYing labor if you're detail-oriented enough. Costs are high for labor + if you do it yourself you can be your own quality control.

      GTSBoy is again on the money. My actual advice? Sell the car. (really). For what it's worth as is, you can sidegrade into something much better. If you care about function then this is the actual move. If you want a Skyline to perform, set aside about $100K to do it. This is NOT a typo. You will see right away these are two very different mindsets. Realistically we're talking full restomod for any Skyline still kicking around. Have an honest think about which one you are.. and what you want to do, and how much you want to invest in this (with no return).
