+1 :) even though mine isn't the cheapest of cheapest RB30 builds it's far from expensive.

I'm aiming for 400rwhp when the GT35R goes on, I think this is going to be the upper end of the drivability limits of my rwd 32 platform and with my setup I'm probably going to be struggling to keep it down that low for now! There is still headroom for a bit more power too ;)

Personally I wouldn't waste money on the RB20 but, of course, I'm biased. The monster torque of the 30 makes for a very nice allround car, I mean I was following Tristan through the twisties on Friday in 4th gear up those hills.. the ol' RB20 wouldn't have liked that much..

+1 i am doing the same thing and building an rb35/30 its fairly cheap to get an rb25 and an rb30 block is even cheaper but remember if you want a reliable engine you are going to have to spend a fair bit of money have you taken everything into account that you will also need to buy?

I think iv made my decision..... i think ill be going for the 25

i think the cost of a 25 could be a little better and it also means ill have more cash to add my big turbo n clutch and so forth ;)

I cant wait.... now ill be in the hunt for 25 half cut so if anyones knows of the ideal place/person to get a well looked after 25 then this would be greatly appreciated. otherwise ill find one :happy:

Man the 25Neo didn't even like it...

I mean it 'managed' in 4th, but def wanted some more down low balls.... Sometimes, knocking it back to 3rd was required to keep up with the cars ahead...

btw, I think go either a 25 or 25/30 combo engine... Make sure you get a NEO so you've got solid lifters and NVCT on both the intake and exhaust...

yeh i thought about a NEO... will that go in with no hassle like the 33 rb25 or they basically the same.... i wouldnt mind a neo because its a newer engine

Too many hassles :nyaanyaa:

BTW my drivability through the hills the other night will disappear when the big turbo goes on.. because power is so early and delivered so linearly is great but once new turbo is on I'll only be able to floor it on the straight bits :(

Umm.. even then I wouldn't be able to floor it until the straight bits.. VH41 + TT would just send me into a tree faster :nyaanyaa:

To be honest though, with the 3L + GT35R I should have decent low down with absolutely insanity over 3000rpm :(

if you want a 26 your better selling up and buying a gtr but if you'd like to go down the path of a 26 in yours with rwd setup easiest option is to buy a half cut as you'll have everything in there like all the hoses front brakes wiring resistor packs front mount intercooler+piping and yeh

same with the 25 get a half cut all is there like brakes, wiring and hoses and shit

cheers

      Yeah its bad eh. Ey! Watch your mouth. Yep, spot on. The rear's are always gone too though from brake checking. I had them perilously close to a tree that we had taken down. I think the tree peeps may have taken it. Either for a trophy, or accidentally.

      f**kin' yikes! That insulation is the shittest stuff I have ever seen. You need to do an insurance job on that f**ker, pronto. WRT to the washer cover, I would have said that there'd have to be some at a wrecker, then remembered that it's a BMW, and reasoned that every single wrecked one would have been tailgating and so the front end would be trashed.

      Ok, so I got myself some X1 wheels really cheap to try out, they're a bit different and I like them but they're really narrow (18x8) they are available in staggered 18x8/9 also but really hard to find.  I kinda dig them, but not as much as the F10 19's I usually run, so these go into the wheel pile.         As I mentioned in another thread, I got a new exhaust. It's an off-the-shelf stainless one that fits OH-KAY. I don't love the tips size and how far they come out the back, I think I might cut the tips off and replace with some smaller (~3") ones that don't extend as far. It sounds really good though, I'm not sure if its just in my head but the car feels a little quicker, more responsive.      I fitted an eBay special front lip. Surprisingly it fit perfectly and all holes lined up. Its a little rickety but I haven't put any double sided tape on yet, I want to clean the front bar up where it has scraped the road a lot and fil in the number plate holes (or, get body coloured wrap to cover them - is this a thing?  I'm not sure if I'll leave it gloss or pain it matte. I really like it though, I don't particularly like the front bar without it, I don't really like the M-Sport and to get anything else is just too expensive. That said, I might need a new one now anyway as I dropped the car onto the jack after forgetting to put ramps under the front wheels. It bent a lot and while it did go back to normal after I got the car off the jack, I do fear I have not done it any favours.    Lastly, my headlights died. Different problems in each. They have gotten much dimmer over the past year or so, I put new (uber expensive) OSRAM bulbs in them but to no avail. One of them pointed at the ground and the other just kinda did its own thing with light working sometimes. Yeah, check this 18 year old BMW headlight wire. I reckon I know why they were stuffed.            BTW, the yellow and black is the power to the Xenons. Yikes. I hunted around an researched my options here. I would have loved to just get a replacement harness but not a thing. My car has adaptive headlights, that is they rotate left and right with the steering wheel. Good condition used adaptive xenons were over $700 each, non adaptive were around $400 each, but I couldn't help but think that they're all around 18 years old now, surely they'd have the same problems. So I looked at newer LCI headlights but they were even more expensive and I couldn't confirm that they'd be plug and play with lots of people having lots of opinions so not worth the risk.  I ended up getting brand new Chinese headlights from MARS. They're very close to OEM with only the angel eyes being a bit different. I didnt want crazy turn signals or sharp DRL's or anything. Not my bag.  They're not adaptive, I thought thats a feature I wouldn't really miss. So I coded that out.  The lights are awesome, they look so nice and they take so many years off the car. The angel eyes look great and the headlight brightness is ridiculous. I was so used to the old ones, I didn't realise just how bad they were. The new ones use the OEM bulbs, Xenon ballast and leveller motor which I was happier with. The only issue with them is that the rear cover is held on by SEVEN screws. This will be a nightmare to get to and open when I need to change bulbs.

      Lets play a game - What is causing my oil consumption?

      Now that you mention it I can see those too. More subtle. The lighting and low resolution makes it hard to assess super well what's going on but what is visible is bad enough to pull the motor.
