hey guys, im not sure if this should be under general Automotive discussion...if its in the wrong section please move it =]

anyways. was just wondering which one would be cheaper, a RB26dett R33 half cut, or a RB30 (R31?) + Gear box + RB26 top end .... planing on dumping it into a S130 project im working on....

or if theres any other alternatives please give me some advice.. thanks guys

I think the RB30 bottom end (no more than $300), RB26 cylinder head (2k complete), and gearbox (which one??) would work out cheaper.

I am pretty sure half cuts are around the 5k mark.

There is an RB30 subforum in the forced induction section on this forum.

a gtr half cut is bout a bit over 6k i think..not too sure... =S i thought about doing a rb25/30 but how much power would that be able to push out of it? and how much would it cost? =S

For R32 or R33/R34

You'd want a 33R half cut for that price, and that way you get the brakes which alone (resale) for ~1500 for the fronts if they are decent with rotors/pads etc.

Sell the dash, cooler and other bits and there is another 700-1k off

So if you dont use all the above its already ~3.5k ... which for a running 26, with loom, and the other lefts overs isnt too bad in my books.

25/30, if you do most of the work and do it right (forged pistons) you should be able to have a running motor for around 3k. If you are using fresh stock internals than a bit cheaper than that. (apparently they are good for 600rwhp) but rb30's have balancing issues so you would wanna get a decent harmonic balancer after you've balanced the whole block.

Im doing the exact thing at the moment.

    • If you mean the alarm immobiliser; theyre internal to the alarm itself which makes that difficult; I couldnt even see where he put it; its not in the same place as last time; but with all black wiring it might be very challenging to trace  I had someone turn the key for me as I know it only primes for a couple of seconds As my post above; I am getting no voltage to the pump at all; but I am testing continuity of the power line (SB) from the pump plug to the relay fine. As well as the negative from the pump plug to a 12V constant.    Yeah; he blammed the no start on a bad battery; said I needed to get a new battery and it'll start. Turns out the battery drained because the tail lights had been on for half the day during the install (the rubber cushion on the brake switch gave out while he was testing it as I have a picture of the car from that morning with the tail lights off..i've replaced that). The battery was turning over the engine just fine for a long time; but got low since lights were draining it so it was too low to test a start after he finished. I bought a new one on his advice...$250 wasted. My original battery charged up just fine and is healthy.    It was running perfectly fine when I messed up the old alarm (programmed out the remotes). He couldnt start it after removing the old alarm; my assumption is that when he unhooked it; he didnt bridge the circuit back when trying to start it. Its always been perfectly fine. The ECU swap and pump were 2 years ago. It's never missed a beat in that time. 
    • This is a big issue for me without the diff. I just have zero drive from the passenger side when drivers side has no traction. Bec's parents place has a crazy steep driveway with odd camber and I have never been able to get up. My bro-in-law's 130i with an (unknown brand) LSD gets up fine as does their dad's Hiace. My car stays at the bottom. We have other odd camber roads around here as we're elevated a bit and if it's raining I can get totally stuck around some hairpins. 
    • Yeah, I am super excited for this.
    • Was the car running before he touched the car?
