so probably been beaten to death, I apologize.

 

so in a nutshell for a 30 swap in a r34 GTR. I would need to:

get the awd adaptor

drill a hole for an extra tensioner

and make the crank collar longer?

will the getrag bolt on directly to the motor?

am I missing anything else? Are there instructions on where to drill the hole for the tensioner?

Yes, Yes, no necessarily (longer oil pump drive is desirable not required), not exactly (the lower bolt holes will be off between the sump and gearbox by the height of the awd adapter. depending on how much that troubles you I've seen some people just leave the lower bolts out, my gearbox was redrilled for the new lower bolt locations.

The rb30 pdf guide has information on tensioner options, and depending on the block you get you may already have to location for the tensioner machined, or you may need to get that done. There can also be differences on whether the required oil feed and returns are in the block or whether you have to drill and tap them

beyond that, motor prep is like any other rebuild (you can decide how far to go), and things like radiator hoses will not fit directly and will need modification.

And finally, I think it is a terrible idea to put an rb30 in a R34 GTR these days. Start with something people don't care about like a 33 GTR instead (no one cares about middle children).

I had a built rb26 with a t88. Unfortunately dumb shit started to happen and I got the car stolen and it came back with a blown motor and turbo. But I stumbled on a rb30 
 

thank you for the information Do you have a link to the PDF on hand? Or a thread with your build?

Or you could just buy one...(from short block to complete engine)

Totally an option if it wasn’t an arm and a leg to ship the motor from there to here. I was looking at a spool short block at one point

will there be clearance issues with the bonnet and the block.

Some have had issues, I did not (R33).  Mate, custom engine fitting requires an optimistic ' suck it and see approach" my 25/30 went straight in, I could have dicked around for hours making mounts beforehand that would not have been required.

Ah nice. I heard there was no clearance issues but I wanted to make sure. 
 

now to compensate for the extra height I need to modify the down pipe, intercooler piping, and radiator hoses correct?

SOME have had clearance issues, block height is about 20mm higher, my point was you will not know until you check after fitting.

    • I can ship Nismo floor mats to you: https://www.oemsoko.co.jp/products/nismo-floor-mats-for-skyline-r33-bcnr33-stagea-wgnc34?_pos=1&_sid=9278c1467&_ss=r  
    • Here's the link: https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6642/misc/G49?frame_no=WGNC34-137122 What you think about it? The same product i found on nengun: https://www.nengun.com/oem/parts/40567/MiPwn5qAMfCfmpxHNDnwn5q9MDAx8J-QiW9sZC1qcC0xMTAtRzQ5LS0wMDE/Floor+Carpet+%2F+Mat+2/0688339eba149c19 Bot i have spoken to 😅 ensured me, that mats are 100% original, oem product. I have my doubts. I also heard what you mentioned, that nengun often offers items that are actual not available... On the other hand mats i found on japanese yahoo or ebay are in poor condition and still quite expensive so i'd rather wait for some better offers. My location - Poland. We literaly don't have ANY market for used Stagea parts so need to search outside Europe.
    • You can’t see much on the other side as the lcd is there I don’t think it’s the same as the m33 beside it as the markings on top is not the same was hoping someone had a good quality photo or if they just happened to have the unit in hand, quickly take the cover off and take a photo to clearly show the marking on top to identify the diode   the unit is currently with an electronics repair shop so I can’t take another photo at the moment hopefully they are smart enough to know if it’s a zener diode or not
    • I'd be very surprised if you can buy new OEM mats. But if you can, I want some too!  Do you have links to the variations you found? Also, where are you located? I found that Nengun is happy to list items to purchase but when you do buy them you'll get an email that it's actually discontinued. As far as I know the variations in floor mats are different colour schemes as well as automatic and manual having a slightly different shape. The automatic ones fit into a manual car without issues, but I think you'd have trouble fitting the other way around. I have photos that show the shape difference if you care. FWIW I bought sets of used floor mats in decent condition at yahoo auctions.
    • Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏
