has anyone here tried to upgrade the old stock dump/front with a new 3" dump/front combo from BATMBL ??

im having major dramas, everything should be fine but did anyone have any problems bolting it on ??

I cannot seem to get the frigging nuts on, they just wont fit. I dont know how nissan ever got these things on the nuts keep hitting the exhaust housing of the turbo !!

well if they are anything like the rb25 turbo ... there should be 2 studs out of the turbo adn 3 bolts that go into the housing ... there should only be the 2 nuts and they are on the back side of the exhaust dump.

Yes it's the same as the RB25DET - and it is Damn fiddly. I ended up shearing a bolt off - and one bolt wouldn't go in the whole way - I ended up just leaving it - Seems to work fine with 2 less bolts ;):)

get under the car to get the 2x nuts off ..

top ones just socket them or use a ring spanner if needed.

I didn't find it too hard, other than 2 snapped bolts, but they were the original bolts and nearly 15 years old.

I didn't really notice too much difference with the dump at all, but there might be a bit more power there. Haven't got it dynoed so don't know.

yea getting the old dump off was a bitch, especially the 2 nuts off the bottom. In the end i have the top 2 and middle 2 bolt screwed in real tight with no nuts on them at all and just the bottom two bolts with nuts on them. I don't even understand how nuts would ever fit on those other 4 bolts, unless they faced the other way which they wont do. Currently the bottom 2 have the head of the bolt (if there was a head) facing the exhaust housing whereas the other 4 have the head facing the dump pipe end. Does this sound right to you guys ?

    • 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 🙏
