Strange, I thought the 21R was used in forklifts only. Learn something every day.

 

good luck. We didn;t get the under powered 21R here in the USDM, so i doubht many of us will be of much help.

 

thanks heres a pic of the block

thanks

 

There was a fellow at work a couple years back that had a 77 pickup with a 21R. As I recall he said it was a JDM import replacement engine, and that it was mechanically identical to the 20/22R except that it had a smaller bore resulting in a 2.0L displacement instead of 2.2 (20R) or 2.4 (22R).

That's about all I know...

 

Thanks..... that's what I read also but another thing, the shop that rebuild my motor told me that the cylinder diameter is a little bigger than the 20r could it still be 2.0L ?

 

Well I bought the pickup in the USA I live next to the border so it did got selled over there just hoping I won't get sad with the performance of it

 

From what I understand, the 21r wasnt offered in the us, only Japan. Junkyards sell this motor saying it is an imported 22r from japan with low miles, when the 22r was an american engine! It has a smaller bore, 2.0 liters. I have heard they are just as reliable as a 22r, just less power. Smaller bore would make me think it was a little bit stronger, as the engine wouldnt be putting as much strain on components. I would also think if a company had a good engine, like toyota, they would much rather have happy repeat customers, then pissed customers who had to constanly buy their parts. That is what makes toyota such a good car company.

 

From what I understand

 

did you forget the rest of your message?

 

Well these is why I was asking and asking we just finished fixing the 21r motor every single thing new till the bone and all parts fixed and new altern, radiator, starter, fuel pump, cable, clutch, seals, etc. couldn't get a better cristmass present so tomorrow is D-day can't wait to start the truck and feel how a new motor runs
