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

      How "plug and play" is the Haltech Pro for R33 GTST

      By MBS206 · Posted

      What are your plans for your blow off valves? Purely plumb back? How soft will the spring in them be? AFM can be tricky to get super smooth and nice, especially depending on the rest of the system, and then can be very easily upset if something slightly changes. IE, even if you run recirc blow off valves, you could still see issues getting it to behave at certain load points as turbos might start to spool, but you release the throttle but it's not enough pressure to crack the bov open to recirc, and you can end up with reversion which can cause double metering, and hence dumping of fuel into the system, and stalling the engine.   If you're going to run a map sensor for closed loop boost control from the ECU, what makes you want to keep the AFM?

      It's not bad, it's just not flexible. And say if you have any leaks between the MAF and plenum, well then your load axis goes out the window. Here's a real world scenario, I blew off an intercooler hose last track day, as the clamp decided to Bluetooth itself somewhere. Still continued to do 2 laps and drive it to the pub for a couple of beers then home. Good luck doing that with a MAF setup

      Is MAF load really that bad? I'm not trying to do big power, my only real desire is VCAM and flex fuel support so I'm not terrified of blowing my engine apart from CA's appalling 95 RON "premium" fuel. Stuff like playing with closed loop boost control and really dialing in my transient fueling and ignition are frankly just to prove to myself I remembered something from uni.

      Thats what ive been doing. Ive got a million questions but i know theyve probably all been answered before at some stage. Todays research included nismo heritage seat covers, s3 projector headlight retrofits and how to remove/paint the rocker covers
