Here's my situation I've got my 32 witch has been t-boned has rb20det ( 264s, gtx3071 with r33 rear, power fc and all the mods to suit) 252kw (no torque )

I've also got a laurel with a rb25 de. I'm unsure if its worth putting all my parts from my rb20 stuff into the rb25de.

Any advice or help would be much appreciated

What are peoples thoughts on using an rb20det ECU with nistune on a series 2 rb25de+t?

waste of time, just get a Z32 ECU (if you're adamant on using Nistune) if not get an old PowerFC for cheap

Model - A31 cefiro

Engine - RB25DE series 1

Modifications / Parts Used - completely stock un open or modified block and head. garet turbo stainless top mount manifould, sard 650cc injectors, hdi intercooler kit,38mm wastgate

Engine Management Used - Link G4 plug in

Fuel Used - 95 octane and E30 ethanole

Boost Used - 8psi on petrol and 12psi on E30

Dyno Tune Results - 290hp on petrol and 360hp on E30

Misc- when preforming a de+t you have a reasonably strong base engine package to begin with. but the one problem you will always face is detonation due to your compression ratio puls your trying to force feed it more air. to combat this I used ethanol blend witch burns far cooler there for lowering your risk of detonation and the ability to run more boost= more power! I have used and abused this engine package for 3 years now with no issues to the (still) stock standard engine package. to this day I still recommend people to use a plus T engine overr a standard turbo engine

Costs - Parts: $4,000 Labour: $0.00 Tuning: $2,000

Hey guys im currently doing an RB25de NEO +T conversion for my R33 track car. I want to use a forward facing plenum but the intake ports on the head are smaller than the FFP ports. Anyone running a FFP on there RB25de NEO turbo engine? The plans are are a GT3076, ID2000 injectors, microtech, extenal gate on a modded 25det turbo manifold. I really dont want to use the factory 25DE inlet manifold.

Cheers guys

has anyone had any issues fitting a standard RB25det turbo manifold onto an RB25de NEO? Looks as if i need to die grind the holes in the manifold where it bolts up to the studs. Have tried 2 different standard 25 turbo manifolds and same thing on both. Not a big problem, just wondering if anyone has had the same thing happen

MODEL: R32 gts

ENGINE: RB20DE

Mods/ parts: R32 gts ecu and injectors.

EBay intercooler kit. S1 rb25 turbo. Pod filter.

BOOST: 12PSI

FUEL: mostly 98 unleaded.

Standard 92 in country tassie when times are tough lot.

Power: don't know but beats modified V8 commodores and wrx's at powercruise.

Other notes: have now done 30,000kms thrashing the fu#k out of the old girl. Held back on posting a review for a couple of years because I don't want to give bad advice to people.

It's now been tested and all I can say is that a turbo setup on a Na with a standard turbo ecu with turbo injectors has the same reliability as a standard turbo engine.

Will try to get to a dyno soon.

cost: approx. $1000

(turbo,manifold, water and oil lines) $400

(ecu and injectors) $200

(exhaust downpipe, custom intake) $300

(other sh#t) $100

Greetings friends.
I am new to the topic but I see that you master it very well. I have 2 rb20 one aspirated and another turbo, I would like to know if it would be better to invest the money to the aspirate to get more profit or simply mix them.

Anyway, I've been thinking about doing the rb20 of + t but I would like to hear your opinion and recommendations.

Thank you.

Have you got two cars or just two engines? If the latter do up the turbo engine and drop it in. You will still need the ecu and loom and an intercooler of course.

    • Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance
    • My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
    • The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.
    • Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
    • Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
