R33 Rb30 Conversion

[StockyMcStock]

turbo way too small? 1 bar of boost should have seen pretty bulk power on a correctly sized turbo.

faaaat torque curve, like it!

i have a Q45 AFM too - reckon you could let me know what your pinouts were on it, and what colour the wires are? mine go WHITE, BLACK, RED in the direction of airflow. i'm assuming SIGNAL, GROUND, +12V but nobody can give me a straight answer

[Bl4cK32]

yer rb20 turbo...its what was on the car b4 i did the upgrade...itll do till i stop saving for a house

torque...MMmmm yer its nice

I'll check the pinouts for ya and post back later

I think the 80mm pod adaptor is causing issues as it blocks off the outer 10mm or so of the afm. Possibly causing a high speed stream of air through the center of the 90mm afm, this is why it runs so rich.

The rb20det pfc loadpoints maxing out is an interestering issue.

Mine with the stock turbo at wot uses load point 19 across the rev range.

Changing my AFM fromt he rb20 to Z32 item changed nothing with regards to load points used but it did change the afm voltage.

In the PFC manual it does state that the H/C is only good for mild mods, bigger mods including cams etc it suggests you need the software to modify the actual base map?!

Strange but true. I wonder if this is only an issue with the rb20det pfc.

Also at WOT Darrens car is running (AFR) initially in to the 10's then comes up to the 11's by peak power, it cannot be leaned out any more.

So there are a few little rwkw's available.

Darren did you check if boost it tailing off at high rpm? It probably is when you consider my stock rb20det turbo tails off to 9psi by peak power and makes 24rwkw less (176rwkw).

Bl4ck32 & my dyno run

63km/h is approx 2000rpm

132km/h is approx 5000rpm.

I suspect mine wheel spun a little from 70-80km/h, hence the dip.

The torque curve doesn't represent the ignition table.

I would like to check out your ign. table Bl4ck32.

Mine is running bugger all, 17degree's at around 2000-2800rpm then it drops to 16degree's until 4000rpm where it drops to 15degree's.

Its very interestering how your T3/4 bush bearing turbo with its large turbine wheel spools almost identical to the small RB20DET turbo.

Thats what Shaun said it did with mine. He needs to see if changing one of the correction tables helps with the fueling issue...

Id say boost does drop off higher in the rpm...i didnt check, but its almost a certainty. There is more left in the turbo, but no room to tune.

Ill call ya today or tomorrow so ya can have a looksie at the settings....

The overlay definitely doesn't do your car justice Bl4ck32.

It seriously pulls so much damn harder than mine.

It hooks up damn well with that 2 way.

The difference in spool between your T3/4 bush vs my stock rb20det BB turbo is nothing.

Which honestly suprises me, yours has quite a larger turbine wheel and compressor wheel, not to mention its bush not ball bearing.

Its given me motivation to get off my arse and earn some money to put towards a new turbo.

I'll definitely be happy with a fairly cheap VG30DET highflow.

[Bl4cK32]

lol....that babyseat in the back makes a hell of a difference too.

I need to sort that sketchy feeling...time for a decent wheel alignment me thinks

I've created a new thread to get to the bottom of the issue of maxing out the AP PFC's load points.

having just read every single page of this thread from start to finish its definitley one of the best ive read on any forum

im another nzer and are building an rb30de engine at this stage. i drive a nissan cefiro with a laurel front current with the sohc rb30. atm its running a rb20e intake manifold and injectors and the 20e loom and computer

here the laurels come out with an rb25de. if i can get the engine out of one of those, can i take the stock loom and wire this to the stock computer and i presume it will run the 30 until i get it turboed

cheers

[masTers]

Does anyone know if the RB20 and RB25 (R32 -DE version) have the same fuel rail? Ive done a quick search and couldnt come up with a thing

Also what size injectors are in the RB25-DE (R32)

[meggala]

the rb25de from r32 has 270cc injectors same as rb20

[StockyMcStock]

the R33 DE injectors are only 220cc though right? :confused: this is what i was lead to believe

[Sydneykid]

the R33 DE injectors are only 220cc though right? :confused: this is what i was lead to believe

My understanding is 270 cc's:cheers:

[Cubes]

RB25de and rb20det injectors are exactly the same.

[StockyMcStock]

sweet - still going to get some biggies though so it doesn't matter

270cc should be okay for about 220 horses at the rears which is not really enough. even on 7psi (run-in tune) they'd probably be maxing out so bugger it.

[Cubes]

220rwhp (164rwkw) is around the mark.. Thats around 80% duty. 92% duty really is too much to make an extra 10rwkw or so.

[fatz]

Doing it fatz style

First you take one of these

Then you find yourself one of these

Then you have 2.6 litres spare

And it make you smile!!!!!!!!!!!!!!!!!

im exited feel my nipples

[Skyrine-Dave]

I would be one of the happiest kids right now

Run in, 10psi

Hey I recognise those SLO31 plates, from certain industrial areas around brisbane on weekends a while back.

Been to the "circuit" lately :warning:

[Skyrine-Dave]

actually i never been to industrial areas... and depends how long a while back is... car has been off the road for 16 months
