pretty sure andrewjzx100 wants it

Yep, that 20 is mine :D

Just went and got the car running so I could drive it to my mates for the swap and I must say boost is good fun after driving around in nothing but a 70s Cressy for a month and a bit :thumbsup:

Ok, well I had my RB20 compression tested this morning and:

1: 92

2: 88

3: 80

4: 85

5: 90

6: 90

So obviously not too good. It's got oil in the water but Ive been told its likely un-related to the low compression as its across the board, not just 1 or 2 cylinders. My mechanic told me its either due to valves not sealing, or the piston rings. So realistically, where should I go from here? Please spare me the comments about selling it or converting to a RB25/26...

Rebuild. Or replacement. Doing a huge, expensive rebuild is pointless on a RB20. If you're going down that path, RB25 it.

Was the low compression from the blown turbo then?

Edit: scrap that. Just quad-rotor it. Cummon. Do it. Or 20b it. Do it. I dare you. No. I DOUBLE dare you.

Yeah I do agree on the huge rebuild thing, but I'm not sure what you mean with the blown turbo... I thought it had a blown turbo - but apparantly not, there is a chance thats gone too though.

If your going the sensible route, grab an RB20 block and drop it in, will cost you f**k all and youll be back on the road sooner.

JIS have an engine, loom and ECU package for $1950, grab it, sell off the loom and ecu, sell your f**ked 20 for peanuts, some parts could be valuable to someone else.

Or JMS have an R32 front cut, no gearbox, low kays for $1500. Grab it, keep donk, sell parts, ??????, win.

RB24...that is all :thumbsup:

Oh right, I just remebered reading that you thought you blew the turbo on that Berri trip a few weeks ago? So it was actually something worse?!

Yeah I thought I blew the turbo, but further investigation points me towards the motor, and then the compression test confirmed it. Like I only discovered yesterday when I was pulling the crossover pipe off to do the test, that Ive got oil leaking everywhere (both valve covers, pcv valve etc), but the crossover pipe was dry..

I am quite tempted to go the RB25 route (just got off the phone to Paul from AdelaideJap), but I really dont want to go in over my head so I'm clinging to the 20 still.

I'd love to build an RB24, but everything that Ive read suggests this isnt the cheapest thing to do...

I was talking to Adrian about his 25 swap. He regrets the swap because the 20 can take abit more abuse.. but you get better results from the 25.

All depends on what you want from the motor and what you do with your car.

I don't know how much it would cost...but 2-2.5k should do it, ill scan a article out of HPI #44, where they start building a RB24, and send it too you.

The 25 is a better long term solution, and it'd be less labour involved I'd imagine - would be a better starting block for engine mods too, cause that extra capacity really helps

-D

mate i've just being driving an automatic hyundai getz around cairns for a few days and let me tell you what a heap of shit! Gutless as all f**k as well

LOL sounds like the one I drove in the Gold Coast, couldnt farking stop , couldnt get it to go.

boot space less then the R34... what a joke of a car. (it was even brand new) disposable car

that it does Ben...Dion i know you want to drop a RB26 in there mate....do that instead

thats tuff luck dion, damn old cars

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
