if you drop a rb26 in you'll have to change so much shit. seriously not worth it. it'll cost more than buying a gtr and you cant sell a gtst with an rb26 for more than a gtr. you'll regret it. go for reliability. buy a freshly reco'd rb20. or drop a second hand one in and sell the whole car if u want a lot more power. it will be sooooooooooo much cheaper this way. don't have to replace computer, gearbox etc...

just do a 25/30 and a big turbo, get some great power out of that.

uhhh... an RB30DET conversion is not the answer to everything...

you've mentioned it on the first page already, and everyone ignored you so just drop it.

just because you have bought one, doesnt mean everyone else can easily pull a good 10G+ outta their asses just to build one to be just like you.

you've mentioned it on the first page already - so just give it a break.

just because you have bought one, doesnt mean its as easy as pulling a good 10G+ outta your ass just to build one.

Correct Rb30 expert! To make it even worthwhile you’re spending big money to build it, and build it right. Other wise it’s just a basic, low revving diesel like motor, pretty damn boring IMHO.

I wouldn't go Rb26, for the same amount you could have a pretty mean Rb25 that’s pretty rev happy.

Each to their own.

umm... have you seen what's involved with most of the guys on SAU who have had RB30DET's built??

Well - she obviously isn't going to build the motor herself (correct me if i'm wrong) but the labour involved will easily make that 10g.

I know you haven't said the answer to everything is an RB30, but your response to everything seems to be.

cheaper than a rb26 and less costly to fix if something goes wrong.

Proof?

point exactly....

you have not even thought about the practicality of having the RB30 in her R32 - the fact that it sits higher and she would need a custom bonnet, or lowering of the actual motor.

now the more important question for Jadles is:

what does she intend to do with the car?

- does she want a dyno car that will produce the numbers?

- does she want a quick drag car?

- does she want a track car?

- does she want a car that will drive from A - B?

- does she want a street car that will be ready for all of the above?

what is her budget?

- does she want something reliable?

when she has considered all of those, then you can throw her the RB600DETT

Thought I'd step in here. Hey Ben how's things?

Anyway....RB30 with the RB25 head and a few other simple mods will absolutely wet over any pissant RB26.

For starters...

1. engine capacity is greater so there is much more torque

2. Rb25 head flows more than the Rb26

3. RB25/30 engine will cost you $200 to fix if you lose a bearing or break the bottom end.

4. MUCH MORE HORSEPOWER can be made from an RB25/30 than any other RB engine.

The only downfalls of the RB30 is they don't have the oil jets for the pistons....which can be sourced and placed easily enough.

The RB30 oil pumps are disigned weaker than the other RB engine so when they are punching out loads of torque they snap the snout of the pump off.

haha if your paying 10k for a 25/30 your being ripped off big time.

Never said it was the answer to everything at all, cheaper than a rb26 and less costly to fix if something goes wrong.

If your not spending ATLEAST $10k, your not getting a very good motor. Slapped together junk piles either don't last very long or drive like dog motors. Why any one would bother with a basic rb25/rb30 has me lost.

We've blown $25k on an Rb25 (not my R32 motor) very easy and it still wasn't perfect, what bob the builder back yardmen you get quotes from amazes me.

A reliable 400rwhp RB25/30 shouldn't cost you more than $6000. I've done the figures many times. You just have to get all the parts yourself and not rely on Mary Markup to get them for you.

a reliable 400rwhp Rb25/Rb30 that doesn't feel like a diesel motor on the other hand :)

$3k for head & head work.

$1k for block, balanced, honed, nitrited.

Forgies - Depends what type? from $1500

Rods - " " $2k I guess.

ECU ?

Tune ?

Misc?

Cooler?

Piping?

clutch?

Thats $7500 alone just for the numbers I posted let alone adding in everthing else plus labour.

Hey Dan, ahh yeh not too bad.

After seeing dan's 32 and hearing about some of the work he's done, i'd pretty much take his word over the majority of people on here. When he gets his shop up and running i know where im taking my car simple as that.

    • (it is a brand new ported mellings pump) I suspect the lack of pressure is due to the leak. It was *not* that low in other logs of oil pressure in the past. It wasn't that hot either, but not far off.
    • Would a Mellings oil pump be a viable option  From my time with a LS, and talking to tuners and LS specialists, the "weak" OEM oil pump is one of the first things they recommend to swap out if I was going to give the engine any high RPM I opted for a Mellings high volume, with the high pressure springs and I never had a issue with it Cost wise they are not expensive in the scheme of things 
    • Just bought a 2002 Stagea 250tRS VR-X Four AERO VQ25DET and spent the last two weekends cleaning and detailing it.. still have to do the wheels and the engine bay but the rest of it came up nice. Imported 2011 to S.A. and I'm the third owner since it was imported. I met the guy who brought it over, he went to Japan and picked out the car, bought it and ordered the wheels. He also gave me a list of stuff he did to the car with receipts. Coil overs (I have the original springs), 3" exhaust from the dump pipe back no cat, Custom dump pipe,(I have the original exhaust), Plenum spacer, 18" custom Work XSA wheels (need restoring, I've made a start..), Shift kit put through the 5 speed tiptronic auto, TV and menus/screens changed to english, Australian DTV tuner installed in rear. I've just had four new discs and new pads as well as all the fluids including the brake fluid replaced. I have all the receipts for the last 15 years and the import papers in a nice folder. Car looks great, goes like hell but fuel economy is not a thing lol.. pics next..
    • I ended up in this rut again lol, and used a shit ton of filler. One thing I can't understand is, even after using a big long block and going in long X pattern strokes, I always end up at bare metal again with no filler, and my repair started at one end of the door and now I've chased my tail to almost the other end of the door. I was thinking of hitting the panel with a hammer where it might be a high spot and making everything low then filling it, I did this on a small section on my other door by mistake and I think I fixed it lol. Is this a bad idea? The other thing is with guidecoat, whether it's the powder or spray, after I sand all the guide coat off, it doesn't reveal anything for me in terms of high spots and low spots and makes it especially hard when it's bare metal (at least in powdered form), am I doing something wrong here, or likely a high spot I keep going over and creating valleys? Lastly, stupid question but, is it possible that after sanding if I only sand over the filler area where I know to be a dent that it's impossible for me to dig into that dent? Unless there are other problems which I missed.
