Yeah, definitely in the US. Can't imagine why I can see it and you guys can't. Hope things change for you.
 
Other than that there is a US online sales site that still has diagrams, but of course they would only be for USDM models. toyotapartseast.com (have to click on the 'More Info' link on each page to see diagrams)

I just logged in and found the same, no images :-(
 
Before I bought my MR2 I had an E30 and use to use www.realoem.com for all the BMW related parts which I think worked better than TOYODIY. I would have thought if sites like realoem can host such a comprehensive and detailed catalog of part number and images of all BMW models surely it should have not been an issue for a site like TOYODIY to host a catalog of toyota parts and images. 
 
I hope someone else can take over where TOYODIY has stopped.

Unfortunately, it is not that simple. Toyota has cracked down on sites using their parts diagrams without permission. Several US sites had to take the diagrams off their sites because of this not long ago. There is now only one US site that still has the diagrams up, the one I linked. They are probably having to pay Toyota to use them.

I just had a quick look at toyotapartseast.com at:
 http://www.toyomotorparts.com/section/toyota-1991-mr2-parts-10609.html
That website could still be useful for ADM and JDM cars (even for 3sge NA models) because many of the diagrams will be similar to US models.
A PITA I know, but you could cross check Toyodiy part numbers with the diagrams on toyotapartseast.com 
May help if you are unsure. 
 

Oh yeah, I forgot that the site got renamed recently to toyotamotorparts.com.

Hi all
 
I also noticed the lack of diagrams on ToyoDIY and was very disappointed :-( but after some trolling of the internet looking for some info on whether you can get a 3SGE sump gasket I manage to stumble across this site
http://www.partsbase.org/toyota/mr2-sw20-1989-1999-jp
It has all the diagrams still just doesn't have the prices which is fine by me
 
Hope this helps everyone  :-)

Good find! Will definitely come in handy.

Good find indeed!

Ive got a copy of the mr2 jap online epc that dissapeared. It has gen 2 +. 3 part numbers. Failing that ive got the toyota software that you put your vin into for the parts listing, but mine doesnt goto 2011, i think its more 2004/5. The toyota software is a pain to get working too

I suppose you found out that a sump gasket is not used, and silicone is used instead.
 
And a good site BTW.
