Replacing Rb20det Motor

[510RB]

Hey guys, i currently have done a ring land in my gts4 (rb20det). Just wanted to know if a normal rwd rb20det motor can be replaced with it or would i need a rb20det 4wd motor..

Cheers..

Im not too sure, there was a bit of pinging involved im guessing.

Im not too sure yet if its a ring land, but its suspected, as there is alot of oil getting straight into the bore, and getting burnt up causing a bit of smoke.

a bit of pinging is an understatement

My old man is ping tone deaf.

He held it down in his EF Fairmont some time back and it was rattling its head off. I was like aaaaahhhhhh stop.... Its pinging its head off, No wonder its blowing smoke in the revision mirror.

I can't hear it pinging he said.

Yeh, well i only just bought it, and now its running really bad...

my guess is somebody thrashed the pants off it running silly high boost and stock ecu, as seems to be all the rage these days.

you can use but you'll have to swap all the sump and things over as that has your front diff in it, whereas on RWD it doesn't.

do a search and you will find some info..

To your original question - the sumps are different between the RWD and AWD versions of the RB20DET - you can't swap sumps between the 2.

I just happen to have a RB20DET from a GTS4 sitting on the garage floor (in Melbourne). PM me if you are interested.

blink_elk, im located in brisbane, which would make it a bit difficult...

Another question... whats the possiability of a head gasket gone on it? Do they let go on rb20dets???

Thanks guys,

I had one let go, but only because it blew a water hose.

I've had a ring-land go, big time (on another RB20DET, not the one I offered you). Chunk of piston hit the end of the sparkplug and shut the gap right down, then shot peened the combustion chamber and top of the piston. Broke a ring, and bent it upwards. Engine ran on 5, sounded like a chaff cutter. Amazingly, the bore is still perfect.

Hey mate, I have a R32 GTS4 motor sitting in my garage, it has the head off of it, comes with front diff, basically consists of:

block with pistons in it

head complete

plenum

coilpack and injectors

I am in Brisbane also. I am moving interstate in a few weeks so I want it gone. I have it advertised in the forsale section but am quite neg on that price. pm me if you are interested.

Did a comp test on the motor today, #1 is holding 50psi, which is not a very good sign, so its time for replacement pistons.

gts4diehard: Cheers buddy, but ive got a spare rb20det block sitting here, gonna replace damaged pistons, put in new rings, and bearings also.

Thanks for the help guys.... will let you's know how i got next weekend when it gets ripped apart...

PS: I moved away from mitsubishi's hoping i wouldn't have to touch motors again... little did i know.. nissans are just as bad.. hehehe..jks..
