rd28 head q's

[Safari Swb]

think ive cracked the head on my rd28t gq safari. does the n/a rd28 out of the c33 laurel share the same head?

[DaveM]

If its the same as the later GU head, then no, they are different. Mine has an oil squirter in the head for cams(?) so I couldn't use the non turbo head, which was cheap as chips, yours may be different?

[Safari Swb]

hope its the same found an n/a engine for cheap as so i guess il have to get the head welded up

[Safari Swb]

well the heads fucked now it decided to start pouring out white smoke and overheated. heap of shit... im going to look out for a complete safari with a 4.2 in it

[DaveM]

I think the 2.8 in something this heavy is the worst thing Nissan could have done (apart from the 3.0 grenade that is).
Mine is absolute crap off road compared to the 4.2, on road its average, and uses a lot more fuel than the 4.2 which is why I have another GQ as my project vehicle.
The GU will eventually get an RB30 turbo put in, but thats on the backburner until the GQ is finished now

yep they are a pig of a motor, would love to do a 4.2 conversion but i may just have to fix the 2.8 up for the moment . just been reading some of your previous posts on your head issues. i dont know whats worse, the 2.8 or the 3.0

i havent taken mine off road yet and on road you have to ring its neck to get anywhere. nissan definately made a big cock up putting this motor in a safari

rb30 turbo would be cool. is it a bolt in job

[DaveM]

The RB30 is more work in the GQ as the pump isnt electronic, but the motor bolts straight up to the box etc, heres a guy in oz that did the RB25, then RB30:

Its common for the gaskets to go on the RD's and heads if the problem is not picked up soon enough

hope my head is not bad . i did get a bit hot,wasnt in the danger zone though. so did you end up putting a new head on yours when you had it off?

[DaveM]

I ended up getting the glow plug out which was lucky, worst case meant I was going to bring a new head back from oz on our holiday

[Safari Swb]

sweet just got the head off and had a look all looks ok so far, am going to disassemble the head at work tommorow and give it a thourough inspection if all is ok il do the rings, big ends and cambelt while its apart
