It depends how far you take it, You could put in forgies, use a RB26 head, new turbo, manifold, ECU etc. and get the bill into the 10k area

If you were to build an RB30 with all the standard gear on your RB25 you can run it off your stock management. Alot of people do this to break the engine in. After that you can just keep adding to the beasty to get it where you want.

If you manage to find a good condition RB30 bottom end you might not have to rebuild it. Otherwise you'll have to go through Nissan/Holden to get new pistons, bearings and head studs. Get the rods shot peaned and the crank cleaned up. New timing belt aswell (forgot about that).

You'd be doing that for an RB25 rebuild anyway so I doubt it would cost any more (probably less). I'd get reading, you'll learn a lot from that thread :happy:

About the torque, 300kw RB30 torque > blown LS1 torque. There evil :)

Or you could just buy a built RB30DETT.. fully built bottom end, 2x GT2540s, complete engine with all the fruit currently making 494rwhp @ 21psi (graphs available), I think he's asking 10k. PM me if anyone is interested :(

Oh and it was tuned by Ant @ Xspeed ;) but sale doesn't include the ECU.

      Need AC Compressor for R32

      By soviet_merlin · Posted

      Out of curiosity, what's the reason for converting? I think @R3N3 might have the Frenchy's kit in the R33? I somehow think of you as the ambassador for realistic and clean street-driven setups nowadays

      V35 Overheat + Coolant Boil & Overflow + Engine not Starting

      careful when running the car after a boil over. Ive heard you can lose enough coolant that it won't show the right temps because of too much air in the system (or something like that). Make sure the levels are good before trying again.  Maybe a mobile mechanic can come have a look with their scan tool ?

      OK, just for some extra clarity - there is more than one option at Frenchy's. 1. You can buy the whole kit - with or without the actual compressor. The whole kit includes mounts, hoses, condensor, etc. That's either ~$2200 or ~$2800. No surgery required with this option. 2. You can buy just the bracket (~$600), or the bracket with the compressor (~$1200). Either of this or the above option "without the compressor" is if you already have an Echo comp or you are able to source one locally. Whatever the case, in this option, you will need surgery done on your hoses to adapt to the new compressor. When I said "the Frenchy's kit", I meant the whole kit in option 1. It is obviously somewhat more $$ than a $1500 OEM compressor. But if I had to spend $1500 on an OEM compressor, I would certainly consider spending double that to renew and significantly update everything forward of the firewall. Another option is to rebuild your original compressor. My R34 comp is currently dead and I will be most likely doing that to it if the spare one in the shed is also leaky.

      I’m thinking that’s the route I’ll  go, thanks for the input!

      V35 Overheat + Coolant Boil & Overflow + Engine not Starting

      By carnoobb · Posted

      Hey all, my 2004 Nissan Skyline 350GT overheated the other day with coolant boiling and leaking out of the coolant reservoir when I was parking. So today, I started it up again just to see if it was a thermostat/head gasket issue. After about 20 mins of running, temps were normal again, no coolant was leaking out and the upper reservoir hose was warm but my engine suddenly cut off. I checked the oil dipstick and cap when it was running and there was no white foamy residue and the exhaust did not have white smoke. I tried starting up the car again but it would only crank, similar to when I had a camshaft sensor issue just that now there’s no check engine light on the dash. Any ideas? Unfortunately I don’t have an OBD2 that can read the Nissan's programme.
