I have an RD28ETI patrol with a cracked block and am stuck here in Kenya. I have searched everywhere and the RD28ETI was never exported to Africa. There are tons of RD28 engines about and TD42's but no turbo efi versions. I am really stuck!! What will the patrol be like if I fit an RD28 with no turbo? Will my injector pump fit on as an addition? It is fine, in fact 1 year old! The TD42 does not look like an option as I would have no donor vehicle for the other bits needed, just an imported engine.
Some
feedback would be much appreciated about my plight. I can get an RD28 and fit straight in with no power!? Or how hard will a TD42 be to fit with no donor vehicle?
Help!!

Hey mate,
I might be a little confused?
I do not know much about Nissans nowadays but back in the old days of datsun 1600's and bluebirds. We would be constantly change engines from a 1600 to a 2l with just a simple change of a few things ie, change sump, brackets and such. I changed a an engine in Toyota 4runner, I put an imported motor into it from a turbo if I remember rightly. Fuel pumps were diferent and I just swapped them over.
Now what I am trying to say here is wouldn't the RD28ETI and the RD28 be the same engine? I can only presume that an oil pick up somewhere on
the block may be capped with a bolt or something like that?
I may be wrong and I'm sure u may have already been down that road? But it is worth a try

Thanks for replies so far. The blocks are the same, but the pistons from the non turbo are much smaller, or so Nissan tell me. The turbo pistons are also reinforced. The turbo could not be put on, it would blow it to pieces, I am told. The fact is that I may be able to take
the block from the RD28 engine and
bore it out to fit the turbo pistons but I am not sure if the crank is the same! It would be a big and potentially costly affair. If it did not work I have two useless engines!! I fear I may need to just drop it in but would love to know peoples thoughts about power issues without a turbo!!
Further thoughts!?

if it had "smaller pistons" then it wouldnt be a 2.8? I am sure that the pistons are likly to be stronger, but I am guessing that whoever you were talking to doesnt know what he is talking about?

Im with Fisho....the pistons might be 'less strong' than the turbo pistons but they will not be 'smaller'!
There are heaps of non-turbo engines that have had turbos fitted but you just have to run conservative. Dont over-boost and treat it with respect and it should be fine.
The turbo engine will have a few different mods like under piston cooling nozzles and maybe a hardened crank but the other one will still be pretty strong.
Whats the chance of getting the non-turbo engine and swapping all the other parts over from the turbo one and build your own turbo 2.8?
I know this will depend on how 'bad' the old engine was!
All the best
Matt.

Thanks guys. Smaller was meant in terms of thickness not width, but a good observation. I have thought about a full swap but that will not solve the piston oil jets problem unless the non turbo block has the holes blocked up and I can just fit my jets, won't know unless I pull the a sump off but the guy in the
shop wont let me do that!!! and was not sure if the injector pump will bolt up! Slightly worried about putting a turbo and efi pump onto a non turbo non efi block. Also my pistons are 0.5 oversize and that would mean an engine machining job! Not pretty here in Africa!
Further thoughts appreciated!! Great
forum!!

How bad is the crack (post a picture). There is a method of repairing cracked blocks, heads, etc. Are they iron or alloy??? So you do this using 1/4 UNF high tensile screws, a tap and some loctite.
drill & tap 1 hole dia before the start of the crack. loctite a bit of thread in. Drill & tap at 1/2 dia intervals, being careful that you don't unscrew the previous thread. Continue until you have gone at least 1 full diameter past the end of the crack. This is a tried and proven method that does work if done carefully. I did it on a Chrysler E38 hemi block (special block) and it successfully completed many 1000's of
miles, both on the road and on the drag strip. Also did it on a 1929 BSA motorcycle crankcase and gearbox case using ally screws. Couldn't see the repair afterward.
