Rb30 Hybrid Upgrade, All Dyno Results

[bubba]

On a whim we decided to build an RB30 and install it in my R32 on the weekend.. a rundown of what we used:

- a prepped block, forged pistons (wisecos I think), rings and 25DE head that had done 5000km in another car.

- standard crank and standard rods out of a quokka special RB30

- 25DE intake manifold

- standard 25DE cams

- 25DE rocker covers

- swapped the exhaust manifold/turbo, fuel rail/injectors etc off the RB20

- New OEM headgasket and a few other little new things from Nissan (oil pickup o-ring etc)

- NDC mains and bigends

- RB25 s1 turbo that I had on the RB20

Block had already gone through a twincam conversion so was drilled/tapped for tensioners etc. We used all the sensors etc off the RB20 and it is currently running on the groupbuy remap from CEF1E.

Bonnet doesn't close properly so I need to sort out the pipework (hitting on the bov and the cooler pipe over the fan) and it could really do with a tune.. got it booked in for the 30th but need to get a z32 afm and some injectors before then

What a big weekend that was!! (even had the manson concert thrown in on saturday night!)

Will update once tuned

Well, after a long wait, I FINALLY got my RB30DET going

Stock bottom end, no idea of kms... Was out of an auto VL though.

RB25DET oil pump

R32 RB25DE head with upgraded valve springs (around 70 pounds seating pressure)

GTR injectors

Z32 AFM

Bosch 040

Cheap FMIC

3" turbo back exhaust (HKS muffler)

RB25 turbo + VG30 rear housing

Remapped RB20 ECU

Makes 206rwkw at 10psi

RB30DET (black) vs. RB20DET with GCG highflow (red)

Got my RB30DET powered Silvia on the dyno finally! Just to get it all running and so I can drive it etc before the power run.

Making 250hp, 290ft/lbs on 10psi, this is not revving it over 5k rpm also. So it's going to be making some nice numbers when I open it up, can't wait

RB20 w/ 25 turbo

(ignore the red line in the above graph, that's when we tried 14psi untuned but it started to ping up high)

RB30 w/ 25 turbo

Only difference between the two engines apart from the extra litre are the 550cc injectors and z32 afm (and a minor tune).

AH RIGHT SECTION NOW, SORRY GUYS.

well guys mine went on the dyno as promised. here,s a you tube link, takes a while to load, done by the racing line where i had it mapped..

car ran brilliantly all morning till 1pm. did 20+ dyno runs , final run was @ 2.17 bar 652bhp@the fly 660lbs torque @ 5500rpm

went for dinner and unfortunately left the ign on. when we returned for some light on road mapping car is now knacked beyond a joke,,

change the ecu,cam sensor, ign amp, splitfires,plugs no joy.. wont rev and on the fuel map it stays the same but when you rev it up, and return to same piont on the map that had an afr of 13 now it reads 21? numbers are the same but afr has changed on its own?. lambda,s are turned off so not them. we puit some 4 bar map sensors on wonder if they have burned out?. will start again monday..bernie

[**RB2530**]

I have decided to stick with stock ECU to see what it is capable of before going to aftermarket...Now if you look at the Nissan Consult data you will see I am right on the limit of the ECU and injectors.

Engine is RB25DET head with VCT connected. Head is stock

RB30 Bottom end with 8.3:1 CP pistons and REV rods.

Turbo is Garret GT3076R on HKS cast low mount manifold. 0.82 exhaust housing

Intake

HKS POD

Trust 600x300x76 F. IC

Exhaust

is 3.5" turbo to CAT and 3" for the rest.

Wastegate is HKS 60mm with 2 1/4" screamer pipe with muffler fitted (yes with its own muffler) Detail is posted in other threads

Engine management is stock. Read my other posts for more detail on how I deal with airflow cut...

NOTE that the ignition was breaking down due to too much plug gap (gap set at 1mm)...You can see this in Dyno charts.

May as well post up here, graphs show run-in tune. Will post up again once full tune is complete, may be a few more months though.

Just posting the comparison between my previous rb25 set-up to the new rb30 set-up. First is a power comparison and second is a torque comparison. Can't wait till the full tune

My turn;

Full built motor, jun oil pump etc

A day in the life of a big power skyline

4am open shed coffee

4 15 another coffee

430 unblot 3582r and manifolds

5am more coffee

510 bolt on new manifold and T51R kai

ring gary to confirm i have dyno for the day

820 stop at gas station fill up rodeo,

945 arrive at workshop

10am unload gts4 put front bar back on.

1015 quick road test to warm up car

1025 everyone climbs under car looking for oil leak,

oil return line leaking 5 hose clamps au't ta do it

1040 strap car on dyno hands wont stop shaking need more coffee.

1050 first run, engine leaning out with new turbo injectors at full duty 18psi

11am change injectors from 740cc to 1000cc sard's

1130 2nd dyno run, alter injector pulse and check a/fr's temp oil pressure fuel pressure all ok

injectors at 54% duty

1150 3rd go, car starts breaking traction at 21 psi 3rd gear, four of us sit in the boot with one on each door sill...power 690 @ all four but nowhere near what i want.

1215 have lunch and sit down chat about the issue of traction and non eventful lower than expected run

1pm gary try's different approch tinkering with timing and loading up the fuel working his magic with the hks f con pro. manifold glows white hot engine takes on whole new angry engine note, everybody grins with expectation.

1440 5th dyno run engine pulls hard the shrill whine of the t51 filling the workshop @ 27psi, smoke starts pouring of the back tyres, everyone piles onto the car, the revs drop and then start to climb again 650,680, 710, 750, 780, 800, 815, 840, tyres start spinning again, gary drops his tools and jumps on the back while craig looks accross at me hanging out the passengers door ,860 870 881 poof! gasket blows, craig
