Top RB20 Club... do you have over 260rwkw?

[grandmasterb]

In Sydney driving approx 120kms a day, livingt at Richmond, working in Chatswood i was getting about 410-430kms before the light was coming on. Driving up from Melb i was over at about 400kms with still plenty on the dial, but filled up as didnt want to get stuckbetween Albury and Goulbourn:)

So economy is pretty good as long as im not getting stuck up it.

Thats not bad then. I only drive about 60k's a day to work and back but have not yet tuned the car or given it a desent run over a long period (only on the track for about 40 laps) and it was pretty heavy on the juice. I put $10 (which was about 8L's) and got about 60k's could go more but light had been on for a while.

Might have to drive EXTREMLY CONSERVATIVE during the week and play on weekends or just keep taking the bike.

i made 298.7 @ 16.5 psi on sat... dyno dynamics

car had been on dyno for about 2 hours tuning so intercooler was getting a bit heat soaked and piping was fairly hot. would have cracked over 300 easy when not so hot

full boost at about 4100-4200 ish and holds dead steady all way to 7500

car drives heaps better now, lots more responsive and a little more top end, fuel is about 11.3-11.7 afrs and Power FC knock count doesnt go above 35 so is very safe.

will post power graph on friday as i dont have a scanner here. will get tuned again in a little while at 18psi and will hopefully get between 320-330rwhp

Pretty sweet dude

Look forward to seeing it around the streets

i've got a 4 door r32 automatic i put a gt30 with an internal gate, malpassi regulator,front mount, turbo back exhaust, no cat converter, bosch fuel pump and on standard boost i made 226hp @ the wheels on standard boost.......and 597nm of torque....

next is ems stinger, manual conversion, head gasket with arp bolts, injectors and boost....

[jazza08]

Is that laggy?? My mate was thinkin bout one for his sr20 but heard it was too laggy for street use as they are one powerful turbo once set up right?

GT30 means as much as hi-flow these days. It seems so many trubo shops are sellign things they claim to be GT30 this and that, but are vastly different to what Garret calls a GT30, or HKS use as the basis of their GT30 series turbos, and the results vary greatly as well.

Very true, without wheel trims and specs etc, its pretty useless information

Sounds like it has potential though! I'm almost given up on getting anymore out of my setup, just cant get anymore out of a 2510 by the looks of things! Damn I wish it was a 2530/35! For the cost and headache's involved, cams aren't happening with mine, too much for not much gain

Might try a differant intercooler, as mine has a 60mm core, maybe something larger will give it that last bit of top end it so desperatley needs!

Someone hurry up and get a 2835ProS ffs!! I want to see how they would perform on a RB20........

[jazza08]

A 2510 is on boost when? Full boost by 3,000rpm?

Heard that thing is soooo responsive, but tryin to get 300rwhp (225rwkw) wud be a task lol

[Chris32]

yeah, depending on load and gear, 1.4bar at just after 3200rpm from memory in 3rd, in 2nd its a bit later, probaly closer to 4000, dies of a bit after 6200rpm, just need to get the last 1500rpm pointing the right way on the dyno, then it would make 220rwkw no worries

[R31 POWER]

Dam thats bloody good responce Chris.So it must be a GT2510 then?

With my motor one sparkplug had cracked the ceramic thing around the electrode and slid down and i'm guessing thats why it idled really rough at times and good sometimes.Still don't know about the knock thou and it still has lots of oil pressure!

[PSI_GTSII]

Sounds like you may have spun a bearing Jase

If so you can still save your existing motor, just need to machine crank, and get resized bearings.

Used to be a regular occurance on my SR20, knock knock knock as you rev

I cant remember if you have cam gears...perhaps fiddle with teh cam timing so that you lost a but of mid range and help the top end a tad?!?!?! It seems you have mid range to burn:)

Also, is your boost tapering off at high rpm?

[R31 POWER]

Since my car is at my dads hes looking at it and put in another spark plug.He drove it around the block and it did'nt knock?what is going on.When it did knock that was just after i revved it.

[DCIEVE]

If any part of the plug dropped into the cylinder then that will cause a small knock, know a person who thought he had a screwed bottom end, pulled it apart and it was just a small bit of hose clamp someone had carelessly cut and dropped in the carby... Fingers crossed!

After a few days at 300hp mine developed a missfire which has now progressed to a stage where the car wont idle..

[PSI_GTSII]

Jase: sounds like you may be lucky

Nick: Your not leaning out and blown the bridges from your spark plugs....?

[R31 POWER]

Ok I just picked it up and it's fine so it was the sparkplug.So who wants a used china exhaust manifold for @$200? it has a small crack in it.

[jazza08]

Shame about the crack otherwise i wud of, did u get any gains off it or did u put it on wit a new turbo or wateva

[R31 POWER]

I'm not sure if it gives more power or not as I did alot of mods at once turbo,ex manifold etc

It gives it a meaty exhaust note but it's got to go,time for some stock mani love

[jazza08]

Ahhh, sounds cool but if its cracked b4 it cud do it again..

And we all know thats not likely from a stock manifold! Get it welded up and sell it for more bro

[jnr32r]

where abouts is the crack? is it SS ?

[R31 POWER]

I'll get a pic tomorrow if you want,but yer it's right next to the weld on where all the pipes merge.It is stainless,one of those china ones and I paid $550 for it new.
