Recommended Posts

Would any one experianced and that has done this before be interested in teaching me / helping me replace my timing belt and water pump? I have a suitable garage and tools minus the puller.

There's 4 very good write ups with pictures on this site. Everything is in them.

Take your time and take mental pictures or physical ones of everything you haven't seen before or are unsure of as it will help when putting it back together.

have the correct tools handy. Get a balancer puller that uses the two m6 holes to pull it off.

Melbourne, Northcote area. I have had a look at the step buy step procedure, I guess i am just not 100% in lining up the timing belt marks.

You'll be fine :) it's so simple. Wind it over and watch the cam marks and that they align, then check the crank. Done.

Question, once I have aligned the the marks for inlet,exhaust and crank, i then remove the tensioner, once the tensioner is removed / released ,will the belt want to move the cams from the original set location because of the tension lost ? if so how is this avoided or rectified?

one other question, just to clarify, the harmonic balancer retaining bolt is L/H thread or R/H?

Balancer bolt is normal thread. Righty tighty lefty loosey. There are a few ways to undo it.

Cams won't move, they're locked.

I'd advise looking at all Diys we have on this website and getting a good idea on how to do it.

Maybe someone here who is close to you can come and help too

People tend to stuff up the tension, usually too much.

Definitely do camshaft seals, and crank seal.

Yep I did, I guess?.

The gates belt is a LOT stiffer than the genuine and dayco belt, so at the same tension of the original, the gates felt a little loose. I did it up a bit tighter and it whirres

Just a quick question fellas,

I changed the timing belt on my r33 s2 det last night, all went reasonably well.. This morning i took if for a drive and every thing seemed fine until I entered the freeway and opened it up a bit, as load and pressure built up above 4.5-5 rpm + It seemed to bet a significant loss of power, now I would also like to mention that I have upgraded the turbo due to the turbo spitting it self the other day, the up grade was from standard - to a Garrett T3/T4 Hybrid A/C CHRA Conversion. (Car not tuned yet)?

is it a possibility the crank angle sensor could be 1-2 mm off even though i make it? or is it just running very rich etc..

I know this is not the right topic , a link to the correct topic would help or some insight would be appreciated.

I don't know much about that turbo. But have been in a few skylines with upgraded highflows and bigger turbos without tunes and they are slow and shouldn't be driven hard until you get a tune.

Did you mark the cas before taking it off?

Should check your timing with a light anyway because no mark will get it back to spot on. A small movement on the CAS is big in degrees, you could be up to 10' out? And that makes a huge difference as well, even 5 is easily noticeable.

    • Actually, it is probably pretty legit. I mean, it's still woke feminazi bullshit academia, but you would have to agree that it is very likely that there would be a correlation between wanting a loud exhaust and scoring at the unpleasant end of the scales for dark triad personality traits. The fact that they found it didn't correlate with narcissism and only with psychopathy and sadism definitely shows that the loud exhaust thing is more of a "f**k you" than a "look at me", and I reckon that rings pretty close to most of the dickheads who take it to the extreme. Remember, this is correlation with tendency to be closer to one end of a personality trait scale than the other end. Of course someone who is at the literal opposite end of the psychopathy scale is going to be so considerate of others that they wouldn't even think about wanting to upset anyone with a loud exhaust. So the finding isn't that "you are a psychopath". Just that you score more towards that end of the scale than someone who doesn't like loud exhausts (on average, not necessarily even for specific individuals).
    • Blitz ER34 at some point hopefully, should be allowed in Gr3 if they do.
    • Stock R33 boost control, with the exhaust, and FMIC done, will boost creep. There is no tuning around it if it is the factory boost solenoid.   If it has an aftermarket electronic boost controller, the settings/mapping can be altered in it.   Oil could be anything as mentioned, however did it ever do it before you did the turbo swap? How much and how often did you drive the car before the swap?   I'm hinging on too much oil supply, or it's not draining properly.   To check, pull the air outlet off the turbo. Is it full of oil? Drop the exhaust at the turbo, does it appears to be oiled/coked? Now pull turbo and check the exhaust manifold, does it appears oiled and coked the same way?   Secondly, the PCV could even be stuffed / not functioning properly and will cause blowing of blue smoke.
    • Almost any ECU would work, from a 30 yr old PowerFC to a new Motec/Autronic. But presumably you want new middle of the road ECU, meaning that you want a Haltech or a Link, most likely. As to which model though? I dunno. I don't keep track of what they have in their current ranges. You don't want a plug in though, because plug ins can start to cause you the same wiring issues that you have to chase up with your stock ECU/loom swaps when an engine transplant is involved. If you use a Haltech (and presumably a Link) you could put the base map for the engine in and drive it around and not even need to "tune" it. It will work just fine. I can't recommend a tuner without a location (and even then I can't recommend many, being as I never use any tuners except myself and my brother-in-law). And not many tuners are happy to remote tune. Maybe they'd be happier doing it for a basically stock setup that just needs to be demonstrated to be working properly. But even then, not being able to be with the car to see what the hell is going on and sort out the inevitable problems that will result from an engine conversion done by an amateur..... unlikely to be enthusiastic about the job. And if you think that just adding 2 wires for the boost sensor is difficult - you don't want to be trying to install and set up an aftermarket ECU. You're going to have to bite down hard on something with either approach.
