Im in the process of starting a engine swap and this thread is inspiring me to forget the 25, and go with a 30 setup, in my r32!!

Im guessing the potential of the 30 is significantly higher than the 25, and if im there i may as well go all out,

like mentioned earlier, im replacing the original motor, might as well have the potential there for future perfomance gains.

thanx guys...for making me wanna spend more money...lol

great thread, ill be keepin an eye on this one.

Cheers

The tradeoff between a 25 and a 30 (unless you're going to spend BIG dollars on the 30) is revs for torque. Similar mods (internal and external) both engines would likely make around the same power, the 30 would make it a lot sooner but unless you build it to rev to 8k the 25 will be able to make similar power due to the higher revs (that's my theory anyway..).

I went for the 30 because I was offered a forged bottom end for a good price, going from the 20 to the 30 was amazing.. the abundance of torque in practically any gear is arousing.. the 20 would never pull up a hill at 2000rpm in 5th! I love it!

      Duncan's V37.......race car?

      By MBS206 · Posted

      Interesting that it has 2 to the USB stick. Are the ones to the USB stick different? Or labelled anything at all? Telstra 4G is Band 28 is the long range one you want, it's 700mHz. I'm trying to do some reading on the Cel-Fi stuff, but I can't find any decent info online that makes me feel comfortable being able to work out the sort of antennas we could get away to swapping it over to. The antennas I'm starting to do some stuff with at work, are a transparent antenna. They're designed to stick onto the window. Which means you wouldn't even have the antenna outside the car. Volkswagen have just started using the exact same types of antennas on some of their new cars (And from the same antenna manufacturer). But, RF stuff is a bit of a dark art some days, and getting it wrong in your car could make for a terrible waste of money trying to swap antennas :S

      What do you do with all the spares?

      By MBS206 · Posted

      I'm not going to lie Duncan, Saturday and Sunday were pretty rough days. The sort of work I was doing would previously have ended up with me spending about an hour and a half chatting with Neil. Firstly about something I had a question about, and then both of us rambling off on tangents.  I think how Neil did things, and his attitude to getting it done is helping me in part to get this stuff done. Then I can actually do the things I enjoy more easily

      ER, HR bonnet question

      By RBjay34 · Posted

      Talked to another R34 GT-T owner, he said bonnet of his car once fell and slammed from full height because of strong wind at a car show and nothing was damaged or broken, so I guess I'm just overthinking some things but yeah, just making sure I'm not damaging the car anyhow cause wanna keep it for a long time.

      ER, HR bonnet question

      By GTSBoy · Posted

      I would say 100% that it doesn't matter at all. I have an Al bonnet and I drop it sometimes, push it others. Have done so for 25 years and there's no way to tell that either has caused any problems (because there are no problems).
