Ok, my RB20 has stuffed a big end bearing, so Im going to need to do something about it soonish. The problem is I have a pretty tight budget.

My options the way i see it are

A) Rebuild a lower K RB20 and swap it for mine.

B) Get a stock 4WD RB25DE, stick my R34 turbo on it and remap my R32 ecu to run it.

Im thinking I could probably rebuild the RB20 for around a 1k including buying an engine, but after reading 666DAN's posts I really like the RB25 idea.

Can anyone give me a ballpark figure on buying the RB25? (has to be the 4wd one remember).

What injectors do the NA RB25's have?

Would I be able to get it back up to my current 200rwkw?

Any help appreciated

Depending on how long you are prepared to wait and how much you want to pay, I'll have a healthey GTS4 AWD RB20DET motor coming out of my car soonish. It'd save you money with being a bolt in, and not have to fark around making sure everything works.

na rb25 from an R32 has the same injectors as rb20det

about turboing it?

I don't know..

I'd go another rb20 or have a look at my HYBRID RB thread in this section where someone posted a link to building an RB24 and 22 and so forth.

however, if you really want an upgrade, you need the money.. then go rb30det or rb26dett

Its actually a T70 turbo - heres what he said:

I'll be finishing the Cefiro with the RB25DE + T70 later today so I'll scan that when we're done.

Last reading was 249 rwkw @ 17 psi

Completely STOCK RB25DE with a T70 600hp, 600x300x100 FMIC, GTR Injectors, Z32 AFM, Desno 600 hp Fuel Pump, Remapped R32 GTST ECU, and that's it.

Yeah i have a problem with my RB20 as well and may need a new engine.

How much?

I've never had anyone be able to give me a straight answer on what is wrong with my car. I think its cursed :

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.

      Factory oil temp sensor in a RS4V without gauges?

      By MBS206 · Posted

      Sounds like the oil pressure light is wired into the oil temp sensor... As it warms up, resistance on temp sensor reduces, hence more current can flow and the dash light gets brighter.

      R34 GTT AC short cycling ? Normal behaviour?

      By Dose Pipe Sutututu · Posted

      If it's cold in summer, then no issue. If it's cutting out every few seconds and you're not reaching your target temp, then there's an issue. One could be the pressure switch and the other issue could be the temp probe inside the evaporator.
