Not much point... for 7k you might get a stock rb25 engine into your car thats about it if you did it on the cheap. Good idea if you want the car for quiet along time and want to get 350+rwhp with the R32 gtst.

On the other hand 7k will get you 250+rwhp if you use your money wisely on the rb20 and if you want anywhere up to 320-330rwhp the rb20 will be fine which is heaps for rwd street car!

If your going for a convertion on a r32 i think the rb26 is a lot easyer to do than a rb25. Also you wouldnt need to spend $7000 to make a rb20 more powerfull than a stock rb25 and you less likey to do the rings on your rb20 if your thinking about running more than 1 bar boost.

try 5k at the absolute worst.

Motor & loom & labour to fit i would envisage a 5k or less pricetag. Its dependant if you fit an RB25 box or not.

For a stock turbo'd RB25 motor, the stock RB20 box will hold no problem anyway IMO. So not worth changing.

So yeah, under 5k easily

yeah cheers for the input, wouldnt a rb26 be pretty expenisve and would u need the different gearbox and other stuff like that correct me if im wrong. yeah i want the car for awhile its mint condition its got 20's on it but i wanna change them to bloody expesive for tryes. hyperdrive said id get the complete motor for 2.5k or 3grand, and instal is 1500, and they said wit the rest of them money do injectors ,z32afm, fuel pump, powerfc.

i think it sounds orright. are hyperdrive good, if herd really good stuf about em but i thought id ask u guys aswell.

Sorry I meant, rb25 + box + ecu/loom + install charges would get up closer to that 7k mark.

I guess alot depends on where u get the motor and who installs it!

Hyperdrive is excellent and only do top work :dry: Check the 34 V-spec out the front if you are unsure along with the many other GTR's around that place!!

lol.. yeah

get the engine done, then put it in if you really want to go that way. I'd ask why though? that sort of power won't be that useable to drive around with..

You can get a basic rb25 engine package (no gearbox) for around $2k with loom and ecu..

My conversion cost $1600 for the engine loom/ecu and about $300 of the misc stuff I needed (labour was me therefore free). Bit of a special price though, guy sold his old car and just wanted it gone.

Hi i have a rb25det in a r32 it was worth it, all up it cost 1,400 and 3,000 for the 25 I have a r33 computer in it and loom, stock gear box and diff, stock intercooler stock exhaust the boost is a 11psi and it goes hard. i thinck a good 13.2 to 12.8

I could not thinck how hard it will go with all the mods eg. a good 310 rwkw.

Also we did the rear grads a bit bigger than a GTR looks tuff with the 19”s

I'm selling a NEO RB25 for $2500 but not in Perth sorry. That gives you an idea of what you can get. $1800-$2500 for the engine with loom, turbo, ecu, add $1500 for fitting and you're away. Call it $4000 but allow a few dollars for the unforseen.

How far could you take your RB20 for $4500? Probably a fair way... but would $3800 get you as far? Dunno.

    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies. 
    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
