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

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      Power steering is probably because someone has nuked the HICAS CU and you no longer have the variable power asist doing what it is supposed to. How much boost are you running? You are aware that any more than 10 psi on the stock ECU is just asking for it to go to full R&R (that's Rich & Retard, which is effectively Retarded and Retarded!) which kills all the power. Depending on the exact conditions, it can just be runnign on the fat and stupid end of the maps, then the conditions change, you make a little more boost and the ECU goes into panic.

      @BuiltNotBought Just as GTSboy said.   If you want driveabilty and more low down torque..keep the stock runners. They are VERY good from a factory. I have them too on my RB25DET NEO and as a GTSboy i have fmic but with stock piping route(i have Blitz intercooler) Iam making around 320 BHP and the car pulls "hard" from like 2,5k all the way to 7k. I have it dyno tuned to mimic N/A power curve and making little less max torque due to the smallbox tranny. But driveability is very great. I had 350Nm below 3k so car feels very quick.   EDIT:  Not my channel but i saw this and i know that is what i want (and i have exactly this)

      R33 persistent issues. P/steering and lag/misfire

      By MissMintyR33 · Posted

      Looking to sort out a couple of issues on my skyline  It recently was rebuilt, however rebuilder long story short did not give two flying effs about the work he did. So moving forward it's running but I have two persistent issues 1) it has a misfire / lag type of issue (was at higher RPMs but I had a dead piggy back ecu removed which improved it) now it's not as bad but still does it at random, I thought it may have been a boost issue I'm running an older turbosmart dual stage controller, turbosmart told me to try running off gate pressure however it still has a lag at random times. It has New MAF, maf plug, coil packs, sparks, CP harness.. injectors tested and cleaned. Factory ECU. 2) Power steering issue. It is tight as anything. Flushed power steering, rebuilt my pump because the bearing was shot. Flushed again still tight (mainly when parking and going slow into my driveway etc)  No kinks in hard lines, replaced the lines I could see had cracks. Still tough to steer.  I was told to shim a coin and place into the solenoid plug? Is there anything else. My steering angle sensor also has a issue. It's a used one I replaced, does it need to be calibrated? I feel like I've tried everything and this car is my voodoo doll.

      One main filter. Each tank has a prefilter to keep rocks and small children out, then the big main filter that also does water separation. Clogged the first one so bad it was like a rev limiter at 3200rpm. Literally just like dropping the throttle off and maintaining rpm!
