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.

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

      Chris' Toyota Mark ii JZX110

      By Rezz · Posted

      Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.

      new 1.5 LSD issues/concerns

      If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
