Good question Mark - I'm buggered if I know !!!

BTW - I got the intake manifold off - what a job !!!! Ahhh !

I've been having a look at how to take the head off - Looks like you have to take the cam pulleys off, (which you prolly need a puller to do) Then looks like you have to take both cams out , then undo the allen bolts under the cams - Hmmmm - might leave this job to the professionals.....

cya :(

I would leave the cam belt & cam gears on. Turn the car over until the notches in the cam allow access to the head bolts on one side, then turn the car over again until the other cam's notches allow access to the head bolts.

Its a dodgy situation as I know the RB20DET is an interference motor and if you remove the cam belt then turn the cam there is a possibility of the valves touching the pistons.

Am I on the right track or is there another way to do it?

Joel - 56mm inside diameter.. (oh and it's a RB25DET). Not sure about turning the engine over ATM- not much oil left in it. I spose it's rooted anyway.....

Dino - thanks :) Smartarse :shake:

Pete - I've done the bodgyist bog job on the Corolla. Rego in 2 weeks dude - What are we gonna do ? You gonna send me the papers or do I just dump it somehwere ? BTW, headlights permantantly on high beam after I tried to fix them, forgot to connect the horn back up so it doesn't work, steering wheel on upside down, tyres won't get thu rego - Anyone got a shotgun and I'll put it out of it's misery ! :D I think I'll sell it for $50 before rego expires - caviat that the new owner has to get the rego papers from Fatz. :( :shake: :D

  • 4 weeks later...

Well, the car is the shop now. And I went round there today to see them take the head and pistons out so we could assess the damage.

Results: 5 busted pistons - Ringlands. Bits and chunks going everywhere when the pistons were removed. (See pic).

The good news was that there was no bore damage and the bearings looked good. (But these will be replaced anyhow).

Interestingly - the timing belt that was meant to have been replaced 5000kms ago looked very similar to a worn orginial timing belt. I wonder what else we will find.

So the Block is off to get decked, prepped , painted, etc. The conrods are off to get measured, balanced, shotpeened, linished and cryo hardened. The head is off for a port and polish.

Should be on the road in a number of weeks - Yay !

Injectors are being checked - if good I will sell them and replace with Sards what ever the results.

Fuel pump (044) will be tested too - If farked, new 044 goes in

Engine Munching Systems (EMS) computer is being replaced by PFC and Q45 AFM.

Tomei 256 Cams going in

Turbosmart E-Boost - Electronic Boost control

Oil Cooler, Larger baffled sump

Nismo Engine mounts

HKS 1.6 mm composite head gasket

--><-- this far from ordering a Trust plenum from Nengun

Yep - I set a record - 5 out of 6 is a pretty good effort ! !

I'm thiking new turbo now - since I'm doing everything else. How's the 3037 Steve ?

Cheers,

The 3037 is pretty sweet:D Cant really say too much from an alrounder package until I have done head gasket and wound up the boost (when my trust plenum gets here:D).

Summary, for a street/strip car - awesome, absolutely awesome. I cant wait to get the traction side of things sorted better though:)

To drive, boost builds alot slower than the stock turbo at first, but doesnt start alot later in the rev range - once around 8lbs comes up (a bit under 3000rpm) all hell brakes loose, just like hitting a nos button.

Goes from around 8lbs to 15 in 2-300rpm or so I guess. Bit hard to tell when you are driving. With 1.2bar dialed in its alot worse - 120odd kph in 4th, 1/4 - 1/3 throttle (what I thought was gentle accelleration) and sideways:). So, until I get this traction sorted a bit better, the boost is staying down unless there is no traffic around. It just hits sooo hard sooo quickly.

The power band is great, can stay on boost through the gears no probs - that is running a 7200 redline. Just traction that is a problem.

    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
    • Lock me in mate, although I'm not sure if I'll be heading up from Goulburn or down from Sydney, either way, return will be back to Goulburn 
    • Sounds good, we will aim to be there! @The Bogan I'll give you a shout if you are heading up to campbelltown for the meet too.
    • Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.
    • Nah that is just crappy GPS mapping, I did have a small excursion (cold tyres, damp track, surprise!), will post up that when I get a chance.
