WOW Dirtygarage you are amazing and if anyone didn't already know it I'm sure you'll start a thread telling them how amazing you are. As per usual you'll build a RB30 redesign the wheel in doing so then crow how great it is and expect all to forget how much in the past you've bagged them as they are a forklift motor.

I would have said something more along the lines of a BOAT motor the way them vl's dirve!!!

Oops shit Paul, Sorry haha we wouldnt want that now!

Andrew you mean the RPMGTR thread :)

Hey Steve, dont think it was race pace. Rhemac was the one i think

My RB30DET with a totally stock rb25 head, cams are stock as well. no mods no port jobs nothing makes full power by 3700rpm and it does not drop off all the way to red line.

Can you get a RB26 to have a flat power curve like this? if so.. show me.

There was also a mark99 here in SA that built an RB29 using an rb26 block, slightly destroked rb30 crank, forged rods and custom low pin height pistons.

Rev'd to 8.5k and made some awesome power. There's a dyno sheet laying around some where that was posted.

The rod angles are of concern but it has held together without any issues so it may be a moot point.

Something else to add to the fire with your rb30 boys..

rb30 block with rb26 crank... There was a post on here a while back from an engine shop down south! dig that up it had some pretty nice looking results!

Since rb30 and rb26 both have the same bore, wouldn't a rb30 block with a rb26 crank just be... a rb26?

Wow :banana:

yes. anyone heard of the hks "hi-deck"....albeit 2.8L

have a search on gtr.co.uk/forum dave, i remember seeing atleast 1 setup on there.

but form what i recall its like the kakimoto hi-deck where its a compression deck with liners

Bottom end first

But yes, I will take you up on your offer from that call

Everyone knows that big cams get the chicks Steve-o

I didn't know you liked doing the bottom end first still, i thought therapy fixed that? ... Zing

Throw away the little ones and put in the 280's.

I want to get rid of them :banana:

I don't know why people are so afraid of spending the money on a big head job :s

Selling 2 kidneys is not advised.

Would be better to throw the money at developing a new block.

A good head job is always the most satisfying way to 'blow' your cash.

PM me a price on the 280's Aaron...i might take them.

Thats an unfair advantage Guilt-Tripper...you tuned it!

Coming right up Sir Boost Alot

nope, rb30 block is taller by 38mm

Wouldn't that completely mess up the compression ratio's then? I'm still trying to get my head around how it would actually work, putting a rb26 crank into a rb30. The block is taller, yes, but doesn't that mean your going to run into problems because the rb26 crank will still have the same travel, even when its put into the rb30

Not too far of the mark

overall terms, your graph is flatter for a section, this one comes up a bit smoother

Do you have a larger pic of the graph for km/h and/or RPM to look at?

I see what you're saying now; if you 'blow' your cash -presumably a 'wad' of it or at least the cost of a good 'pearl necklace'- on a good RB26 head job you can't 'come' at or 'swallow' the idea of the RB30 being better, and suggest that anyone who thinks otherwise is being 'sucked in'.

Have I got that right?

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
