My 32 makes 250kw atw and im running a rb20 box, second gear synchro is rooted and the box whines like an annoying girlfriend in the 1st 3 gears, it is driven everyday with a 5 puck sprung center clutch.

At least it will give you a bit of an idea what to expect, i have a spare 20 box here but ill be fitting up the 25 box very soon

would a rb20 box be able to handle 230kw all day everyday??

street driving maybe with a soft clutch??

I killed one with 183rwkw RB20 and one with 183rwkw RB30 (2nd one went a lot faster with the RB30).

Could have been the button clutch and too many 2nd gear clutch drops though.. :bunny:

Gee he must be gentle with it!

A mate managed to smash one in a HR 31 with a NICS RB20 with a R34 Turbo and Mines ECU! This wasn't from excessive thrashing either! :S

Mate 2 managed to smash one in a HR 31 Passage with a silvertop and GT2530 (don't know power figures for either, but not the best track record lol).

I'd be kinda wary of them myself.

      It wasn't about the dollars. I mean how she didn't like the loud exhaust and you had to change it again 馃槢

      I'll tell her I put in a new air filter on it, which, it would have anyway with the ITB's In the end she isn't to fussed, she spends lots of money on hair, nails, make-up and all the other "required" beauty products that women use, plus I grease the wheels with shiny gifts and holidays wherever and whenever I can She once questioned my car spending "budget", but after itemising everything she spends on herself, and what I spend on her, and the fact that I don't care if she does or doesn't wear make-up and fancy pants perfume, or requires new outfits for every wedding, funeral or anything else she deems worthy, and I'm quite happy to go "real" camping, instead of staying in hotels or jaunts on cruise ships, she decided not to press the subject on how I spend funds, and has never asked "how much did that cost" again, so a win to me And how often can you say you really get a win with the fairer sex? She is a good woman, and in the big picture, I'm really lucky.....that she hasn't killed me yet

      Will the clear coat dissolve the ink tho?? I thought about clear vinyl tape too. Thinking what to do haha. The one I have now is cracked in 1 spot, otherwise mint. Plus the MINES one is much thicker plastic material so its not flimsy at all.
