I Thought I Had Blown The Engine ...

Here's a short story:

Just took the skyline for a quick spin to try a new fuel map.

When there was no traffic I floored the pedal a bit more (about 4000rpm) ...

The car started to move forward and came on boost - suddenly - BANG!

Yes! BANG!

:wacko::unsure:

OMG! (It was a very loud BANG!!!)

What had I done?? (my fuel map wasn't that bad, was it????)

I rolled (engine died off) to the left and opened the bonnet, but I could see no damage ..

So I started the engine again (and secretly hoping that everything would be fine)

, but it ran very, very poorly.

Also I could barely keep the revvs over 3000rpm and the engine would die off often.

The car made a lot of black smoke and noise either ...

A nightmare!

In 3rd gear and with a lot of smoke and sweat I made it somehow home.

(I was just 3km away anyhow)

With a flash-light I checked under the car and could find no oil leakage or obvious damage.

Again I opened the bonnet and there it was ->

The newly fitted hose joiner had come off .. :)

PHEEEWWWW! Seems it is my lucky day!

(Thanks for listening)

Ohhh ... I see what you mean!

Thanks!!

Given where the clamps are on the hose, and how long the pipe/lip is - doesn't look like it was done up correctly.

Make sure you get the clamp behind the lip this time around.

It was my first time ;), and I just recently fitted a new turbo ..

So I really thought something massively wrong has happened :)

Obviously I made a mistake while mounting the clamps..

Nonetheless interesting to see that there is actually much pressure at work ..

I will have more respect now for the PSI figures!

Yeal lol thats happened to me heaps of times so loud you instantly think shit what have i done then the csr idles like a rotary.

pretty common occurrence

you can unplug the afm if that happens, it will limit revs to about 2500 but it drives a bit better than with it plugged in (reverts to a default map)

one time my r32 spat the whole lower half of the hot-side pipe (from under the airbox to the fmic) into the bushes

i couldn't find it so i had to limp it home :(

wait till you get one come half off, it runs like shit on boost but idles fine and drive fine off boost and cause it only came half off you can't see it easy and have to pull half the friggin car apart to find it was the one that joins the back turbo to the front one :rant:

I blew my cooler hose going through the NATO park near stanwell tops, I also herd the bang and black smoke, All my intercooler pipes seemed fine and I started to worry that it was something else, I decided to remove my front bar on the side of the road (had to wait for dad to bring tools which took him 2hours to get to me) and the pipe going into the passenger gaurs was off.

Massive pain in the ass especially if it's hard to get too !

How good is it though when you find it - that sense of relief that it was nothing serious :) Although the bogans in falcons/commodores flying past while your bonnets open and they scream out piece of shit skyline is annoying

i've never once had a cooler pipe blow off in 4 years, last 2 years at 20+psi. best clamps ever, apart from those fancy wiggins ones....

Use these, everything else sucks.

Agree that blowing a cooler pipe off scares the shit out of you, sounds like you put a piston through the block and then it won't idle, worst feeling ever.

Hi,

Yes, now that I know it is common it is -> LOL, but yesterday it was -> OMG!

I have a Nistune ECU and I was trying a new map ..

LOL good read, very common.

Get that car tuned properly with the new turbo as the stock ecu may just blow your motor.

That's good information, had I know I would have had less stress ..

It was difficult keeping the engine alive and it would not take any load at all.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
