Sorry to be the one to bring this up for probably close to the gazillionth time.

But before you mention it, yes I know there's a search function and yes, Google is my friend, etc, etc.

But anyway, I've been searching through forums and the like for a week or so and a lot of threads regarding this swap are from quite a while back. '07ish.

Also the reason it's in the WA section is due to possible price differences as compared to other states due to Perth being in the middle of Whoop Whoop.

(so delete, close or move if absolutely necessary, but If my there's a recent thread or something I've not found please let me know)

I was just wondering, due to the fact that none of the sites really tell you, how much your looking to pay for a RB25DET half-cut these days in WA? (I'm assuming there'd be some form of price depreciation)

Whereabouts in Perth is capable/trustworthy of getting these in in good nick, low km's and at a decent price?

And any other associated costs? (installation, possible tuning, wiring, etc.)

(probably worth noting, is my pathetic mechanical knowledge, I reckon without help I'd be in struggletown getting the engine out by myself)

A ballpark figure for each of these (based on recent experience, inside knowledge, etc.) would be greatly appreciated.

my cousins son was looking at getting a half cut S14 SR20DET at jap performance place in ossie park to install in his NA auto S13, they quoted $3000 for the half cut and $2500 to install, i know that its not a 25DET but gives you an idea of what your up for, remember japan is not pumping out any new 25s anymore and demand is quite high

Is there like an FAQ thread about this conversion (not a tutorial, I've read about a million of 'em) someone could point me in the direction of?

I'm trying to find out what parts are interchangeable from the 20 to the 25. (manifolds, cams, etc.)

To see whether I'll need the half-cut or if just an engine, g/box and loom will cut it.

Cheers.

Edit: Also is there any significant difference in power or ease of installation between the S1 and S2 RB25's?

Mechanically, there is no difference between a series 1 and 2 R33 era RB25.

Things like ECU, coilpacks, TPS are different (and thus the harness).

RB20 & RB25 exhaust manifolds are the same.

RB20 and RB25s1 coils and igniter are the same (s2 went to igniters on the coils), RB20 and RB25s1 AFM is also the same.

Use the P/S and A/C that are already in the car, should all bolt up to the block fine.

      R33 GTR running -9 with no tune

      By Duncan · Posted

      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

      Coolant leak?

      By Duncan · Posted

      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

      Coolant leak?

      By GTSBoy · Posted

      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.

      Is it alright to top up with just another green coolant?
