At this stage I'm not sure, considering taking this oppurtunity to get out of the game for a while, as I've owned the car for a year or so and only done 5000-6000km in it its hard to justify how much money I spend on it.

Have got a few options but might have to deny the dream path of glory ;)

Hey there Driver - the real question here is can you afford to be replacing turbos when you get your car?

It seems like a bit of a lottery as to how much boost they will hold - I was running 14psi when one of the turbs spat the wheel out the ar$e end:Oops:

Had to buy some 2530's to fix the problem:elaugh:

Steve is a total nutter (j/k steve)...oh, & he owns a performance workshop so he can repair things a little cheaper since he does all the work. Keep pushing em Stevo you'll get those turbs soon enough:D

Yeah i run 16 on then but im unsure if they are completely stock turbos have not had the car that long and still finding stuff out about it, was running on about 16 when i first got it ad 10 on low.

On this question how much boost should the fuel system keep up with?

cause just the other night my electronic boost controller scewed up and i wasnt really paying attention to my boost gauge but i thought to my self damn the car seams to be hammering and out of the corner of my eye when i accelerated my boost gauge went past 20psi and i was like ahhhhhhhhh but the wired thing is it wasnt detonating was running nice and the turbos seem fine and it wasnt just for a second it was on 20psi of a good haul... but i was so worried afterward. would the stock system be able to handle something like that?? or would there be something no standard there?

its really a lucky dip when getting stuff imported.

As they say, by the time you can audibly hear the car detonating from within the cabin, its too far gone.

We managed to squeeze 210awkw out of mine before the fuel pump started maxing out. Some get a little more, some get a little less.

mmm well thats ok cause i have an after market fuel pump know that for sure apart from it saying on the engineering papers you can hear it :D

but damn if it was detonating im sure the engine would have suffered but there is no signs of it, engine still have good comp... or a i was just really really luck i got a new controller in there since so no more going above 15 for me

Clarification: So 1bar worth of boost on the stock turbos seem to be okay? Is failure past this because of the actual boost or the fact that the turbine shaft speed is too fast causing delamination?

The reason I ask is because I am about to undertake up grades in the way of a competition dump pipes and y piece as well as a retune on the dyno. I already have a larger free-flowing FMIC and pods. What worries me is that with all these mods I will have less restriction in the system and therefore less boost. If I then up the boost to 1bar I would imagine the shaft speed will be greater than a near standard system with 1bar.

Am I on the right track? If so, should I tune for 0.9bar or even less?

So is it the boost or the shaft speed?

Just jammin here but I assume heat would be the cause. Differences in thermal expansion between the metal shaft and the ceramic exhaust wheel could cause it to detach...

Whether the heat is a result of exhaust restriction or excessive shaft rpms would depend on the setup I spose.

If so that is good news, as taking out restrictions should also drop the thermal loading. I am putting on 9in long dumps that are ceramic coated so it should keep a lot of heat away from the turbo and engine bay.

Does this sound right? Can anyone concur?

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
