Hi,

My skyline keeps blowing a hose off the turbo. Its from the rubber turbo elbow then i have a small 10cm metal pipe connected to the intercooler piping but this pipe has no burs/beading around it so now it pops off every time i boost it. Wondering where i could get a pipe like this locally i think its the 2.25" or 2.75" (stock intercooler piping size for rb25det) or who can add the burs/beading around the pipe. This is kind of urgent as its impossible to drive the skyline off boost if you knowthatfeel. Or if anyone has one lying around it i would like to take it off you.

I have the head of my corolla out again and i need it machined flat, check for warpage etc who is reliable to do that (north side prefferable).

Thanks

Autobarn, supercheap, they have bits of pipe, may have to ring around as they usually have only two or three bits at a time on the shelf.

They have bends and eveything.

Even autopro and repco prob have it too.

Or

you can use two clamps if you have the room, works on mine. no lip. 10 psi.

Post up a picture if you can. I'm sure someone will have something

Ohhhh.. i forgot about my stash of bits of pipe, gimme a minute.

nope sorry

I need this done asap so ill check out natrad or fyshwick tomorrow. Its tuned for 21psi's for e85 tune or so but always overboosts initially to (even higher than) i thats when it pops off (motor hasnt popped yet though)

Autobarns and such only have 3" pipes and they are too big

What about head reconditioning/machining who would you guys recommend ?

While im still here, i have a electronic boost controller due to internal wastegate, but the boost controller IN hose is connected to the intercooler pipe AFTER the intercooler (basically near the throttle body). If i weld in a nipple and connect that hose right near the turbo so on the pre intercooler side would that prevent the initial overboost ? My theory is that its taking some time for the boost contoller to react initially since its so far away from the turbo.

could just use T bolt clamps, my setup has no barbs and hoses stay tight at 15psi, just make sure your using the right size hoses as i was reusing one of the factory ones that look pretty much the same on both ends although one side was slightly bigger blowing off all the time until a new 2.5" joiner was bought

Yes, read ebc install instructions, and you may find (depends on ebc) one near turbo and one at intake plenum. get them the right way or it wont be good.

Keep hoses as short as possible, i think less than 600mm is recommended. Use filters on the hoses, keep them close to the unit, (less than 100mm i think)

I was using a HKS evc4 but its gone funny and gives serious overboost, so im not using it anymore, unreliable. going off the actuator. if i want more boost ill use one of those bleed valves.

    • Nissan/Pitwork is fine stuff. HKS is just marketing wank. I personally wouldn't do the idler if it is already new. If it looks and feels fine, it is fine. But as D says - it's cheap to add it to the job. The water pump ditto. Even more so. If it show no signs of problems, then it is nearly new - leave it.
    • 1. I can't see a location on your profile but you do mention GBP so I'll assume you are in UK. In Australia, CBC make a timing belt kit with the gears and idler and tension bearing and that is what I use without any problems. I'm sure OEM or HKS are also fine but I wouldn't pay extra for HKS over anything else. 2. Yes, I would always change the idler and tensioner and the stud and bolt that hold them in. Assuming they were all done last time it is highly unlikely you would have a problem, but they are very cheap to add to the job considering the time it will take anyway.  3. No, you don't need to lock them as such (I think that is more for engines without timing marks), but you should make sure they move as little as possible once the belt is off as you can hit pistons on valves if they move too far. As always, make sure you line it all up to top dead centre with the timing marks aligned before you take the old belt off.

    • Hey everyone,   I’m looking for some advice on replacing the timing belt on my RB25DET Neo-powered 1998 Skyline. The engine was fully built about five years ago, including a fresh timing belt, water pump, and other essentials. However, since then, the car has only covered around 2,000–3,000 miles. It’s currently making around 650hp.   Even though the mileage is low, I know timing belts have a time-based lifespan too, and most recommendations suggest changing them every five to six years or 50,000 miles. Since I’m at that time mark, I’d rather not take any risks and plan to swap it out soon.   A few things I’d like to hear opinions on: 1. What’s the best belt for this setup? Should I go with an OEM Nissan belt, or is the HKS fine-tune a better choice given the power level? 2. Would you bother replacing the idler pulley and tensioner at the same time, or only if they show wear? 3. When swapping the belt, is it necessary to lock the cam and crank gears in place, or is lining up the timing marks enough? I’ve seen different approaches, and I want to make sure I do it right.   The water pump was changed with the rebuild and isn’t run off the timing belt, so I don’t see a need to replace it again. I just want to make sure I approach this the right way.   Any insight would be much appreciated. Thanks!
