More details. Its not unusual for ANY OHC motor to snap camshafts on installation (even post install) or removal.

OK it does sound alot like the RB26 problems (considering its pretty much a cut down RB anyway). Theres no one solution that will fix the problem. Not even a dry sump will fix it without other work. You need: Oil restrictors in the head Enlarge oil return gallerys (drill + die grind) Cam baffles (to stop oil being blown out to the catch can) Sump baffles External head oil drain I can't think of any more at the moment (and ive gotta go to work) but you get the idea.

Sorry for the late reply completely missed your post. The main problem with arias is the amount of silicon they use in their pistons. If they start to crack, they will continue to crack until a catastrophic failure whereas a low silicon piston the crack will stop before a complete failure. You will still have to replace the piston but that should be all you need to replace. The reason Arias use silicon in their pistons is in an attempt to have them display expansion characteristics somewhat like a standard cast piston. Its your call in the end but other brands like CP are just as cheap.

I think you'll find bolt-on goodies for CA18s harder and harder to come by. There's still more than the 4As but no where near as many as the SR20. And sorry Trev you're making absolutely no sense.... CA18s are unreliable because people aren't prepared to do the work to make them reliable under abnormal conditions. RB26s suffer from terrible oil control problems from the factory. If you bolt a set of semi slicks onto a standard GTR and go circuit racing you'll likely end up with a dead motor. Therefor serious RB26 owners spend time and money solving the oil control problems. Likewise CA18s (I suspect) also have problems with oil control (going by the number of spun big end bearings Ive seen). So either you spend the time and money researching and implementing solutions or just put up with unreliable motors. You can't blame them for failing because of your neglect and abuse.

There are manufacturers that make them certified to ADR standards and supply you with a letter you can produce to the po-po. Theres even one Ive heard of that will fight to remove a defect of their bonnet for you! From what I understand they haven't failed yet.

I met the school bus going the other direction just coming over skyline. Not something you'd wanna see if you were doing perhaps alot more than the speed limit!

I haven't forgotten about you Woodstok but I don't have the backups myself at the moment. I had a mate migrate and backup the largest sections of the site because my ADSL was shaped at the time we moved, so I'll have to get the full backup of the site from him sometime soon.

First and final warning. Don't abuse moderators, or anyone else for that matter. Next step is a Ban. I suggest no one answer this guys questions until he learns to ask nicely and apologizes to Redwarf (who happens to be one of the more knowledgeable members of this site).

5K you should be able to do yourself. A workshop conversion for a CA18 I would expect to budget somewhere around the $6k mark for a drive in drive out.

LOL...man, screw the gold. To me the ultimate toilet is now carbon fiber :D

IP resolves to Slovakia so that might explain a bit.

But thats forgetting that the shock absorber is a MAJOR part of the suspension. The difference between a $200 and a $2000 set of correctly setup shock absorbers is MASSIVE. Hopefully I can post lap times towards the end of the year to demonstrate this. Even with the lower COG, because you've now moved the shock absorbers out of their stroke range AND they're now incorrectly valved because of the higher rate springs your handling is going to be worse.

So get springs made to suit your requirements. There should be no reason for anyone to cut springs!

ARIAS are ratshit. Use something else! Ive seen good result with CP pistons.

Whens the funeral? I'm starting to wonder if we should be outright deleting threads like this because of the possible liability they create... As for your question. They're progressive springs and you're just going to have to experiment. Start from the small end and take off one coil at a time. Still a really dumb thing to do.

I take it this is the GT4? The turbo technology is 10+ years old. By todays standards the turbos probably poorly matched to the motor. For instance my GTiR T28 doesn't come on song until 3700rpm. By comparison a brand new Garrett turbo around the same HP comes in at just under 3000rpm. Its a massive difference. I'm about to upgrade to a 470hp turbo (GTiR is 320) and the lag is virtually the same. Thats how far turbos have come in the past 10 years. As for fuel economy...well the thing is 1.5 tonnes! and AWD! I get perfectly fine economy in the sillbeer (well...before I put the aftermarket ecu in, still hasn't been tuned). I wont bother debating further caws it seems like you're firmly set in your ways.

Yea who would ever want an efficiency multiplier. Lets suck power off the crankshaft and waste heat energy out the exhaust!

Thanks guys, had a good day. Might do something on the weekend...not sure yet :locked:

Yea I'm not surprised. Pretty easy to run up a big machining bill. And if you think you can get away without any machining, you're kidding yourself!! Play nice now boys!

If you're rebuilding you've left out perhaps $1,000 worth of machining costs.

He meant stands either side of the diff on the axel. And I agree jacks should never be used for supporting the car, just to get it up there. Right tools for the right job.

More like V2.1b See what happens when you try and move an annual event :party: lol

Have you considered carburettor icing?? With your location I think its a big possibility. I'm not sure how you'd test for it on a car but for aviation ground checks we run the engine up and turn carb heat on. There should be a drop in RPM (due to the less dense hot air) and if theres icing the RPM will then pickup again. You can use this ATSB chart to see if the conditions are right for icing. http://www.atsb.gov.au/pdfs/carb_icing.pdf

I do have a backup but with something like 2gb of images it wont be uploaded in its entirety.
