Hey guys, the turbo on my 32 is just about gone and i'm looking at replacing it.

Currently have an rb25 turbo, however i'm thinking about replacing it with something brand new...

I'm not looking for much of an increase in power so i was wondering what's a cheap (quality) bolt on for the rb20?

p.s. I've looked in the 'rb20 turbo upgrade' section, but that doesnt answer my question...

Rb25 turbo is a very good upgrade if your not chasing too much power and just want a cheaper alternative.

It will get you to about 180rwkw with supporting mods, but people have been known to make more power.

You really wont find anything more cheaper, and as good quality as an RB25 turbo.

If you want something bigger, you can go to a RB25 high flow, which would be grand new obviously. Depending on the size of the high flow that will be able to get you into the 200rwkw+ bracket, but again with supporting mods.

Supporting mods would include;

Fuel pump - BOSCH 040/WALBRO/GTR

Exhaust - 3" turbo back

Intercooler - Front mount (eg: JUSTJAP kit)

Tune - Either stand alone ECU (wolf, microtech, power fc), piggy back (e-manage, or an SAFC II (fuel computer) or REMAP (most popular, CHIPS & RETUNE'S the standard ECU)

Injectors - (Over 200-220rwkw) GTR injectors

Have all the above, plus a little more. Car has been dyno'd at 192rwkw. Just wanted to go something new so that i know it will last... CRD, which of the garret's are a bolt on for the rb20?

Awesome. Also wanting to know the same, which ones bolt on to RB20 as all the turbos say they are T25 flange, when RB's are T3?..

GT2860RS is a good upgrade for RB20 though! Very responsive turbo's.

Sell me your RB25 turbo! :(

Why doesn't the rb20 thread answer your question? you can see how much power you people are getting and then see what turbos they use...and then you can do some price searching...i can tell you off hand though...that the common upgrades besides the 33 and 34 stockies are...hks 2530, hks 2535, gcg highflows, slide highflows, kkr430s, kkr480s...and a few other chinese brand turbos...all these will come with a T3 flange and will bolt straight(dump pipes might not)...obviously they will make different power and have different response but it should give you a good starting point...

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