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

[boostn32]

OK its been a long time since i made a post, but just an update, i have all my engine parts back from the machine shop and im still aiming to crack 300rwkw. it may seen like a big ask but i know it is possible.

I do have to say to all that want near 280 - 300rwkw it is not cheap at all. but it is very interesting in trying to make good power out of the RB20. Sure i could of gone a RB25 or one of the other combos and it would of been a lot easier but that wouldnt be a challange.

It seems like im almost there with the build and then i need to spend more money. Its taken a while but im about 2 weeks away from the first start up of my new engine. and then its only a matter of running the engine in and then seeing what it can do.

Awesome Boostn32, care to share the specs?

[silver gts-t]

So whats your cold starts like with the fcon silver gts-t? mine has very doughy throttle response until its atleast had a couple minutes to warm up.

<{POST_SNAPBACK}>

actually start up is perfect..

when i turn the car off it has a habit of running for 2secs then shutting down after the keys are out sometimes..

also it needs more revs in lower gears, used to be able to slow down to 1200rpm in second and just press the accelerator, now if i do it i get a bunny hop effect.. and in 1st its the same under 1500rpm

[silver gts-t]

Yeh BD4s use one of those thingie type dynos too. They were saying it reads a bit higher then that other type of dyno thingie that most places use...i really dont know what im talking about:)

<{POST_SNAPBACK}>

yeh the dyno is a different type, they really spare no expense with their facilities..

I have the same problem too.

Do you have bigger injectors? I was told that it could be because at low duty cycles/rpm they open too much casuing a hop/jerking effect.

Cheers.

[silver gts-t]

gtr injectors

u?

[Interloper]

Nismo 555cc

what are gtr ones again? 440?

Shouldnt be at all related to injectors if its tuned correctly

The car should be like factory.

Mine was with 740's

[yogi000]

thanks for that informative post roy.

i'm using r33 gtr 440 injectors, alittle jerky when cold otherwise good @ low revs, if my memory serves me right it also has to do with the ECU fuel cut deceleration setting.

[Bunky_r31]

not an rb20 but i've been driving my mates sr20 silvia with hks gt2835r, he has 750cc injectors with a pfc tuned by lumpy,

runs and idles and drives perfectly on and off boost at any revs

think that would be cause of the power fc?

so tempting to gank his turbo haha but still need an ecu for the old redtop

ahh well i'll get there one day

I will share specs once the power level is reached, i will say it has Arias forgies, HKS cams undisclosed specs, microtech, 700cc injectors, custom plenum, atm it will have a trust TD06 turbo kit but will be upgraded.

are you using standard rods?

you setup sounds simmilar to what ive got going right now.....results will be interesting.

[boostn32]

Yes stock rods that have been preped, block has been modified for extra oiling and using RB26 mains that have 4 oil holes in stead of 1

[silver gts-t]

another note, my temps were lower than normal also..

only thing that it could be put down to is i dont run my cooler pipe over the radiator, it runs under the cooler back to original piping..

[DRFT32]

Hey guys..just thought my effort was worth posting...

93 R32 GTS-t using completely STOCK (un-chipped) computer and stock auto transmission i got 208.1 RWKW at 1.4 BAR

other mods are

Cat back 3" zorst

front mount incooler

os gieken adj cam gear (exh only)

Arias Forged pistons 20thou ovesize

ported and polished heads

1mm oversize valves

match ported manifolds

ported exhaust manifold

high flowed VG30 Turbo

Sard Adj Fuel Reg

Fully balanced bottom end

AVCR boost ctrl

k&n flat panel filter

standard injectors

GTR Fuel pump

so after a manual conversion some injectors and a power FC should maybe hit around the 260 RWKW...

i am surprised at the stock computer getting this far..well done NISSAN !!

[Interloper]

I had mine dynoed again on Dr Drifts brand new dyno on friday night....

208.8rwkw at 16.5psi.

However, the stock actuator on the R34 GTT highflow turbo is only rated at 7pounds (i think) so it can't hold boost properly and it spikes badly to almost 19psi. On cold days (low ambient temps) it spikes even worse so i'm looking at changing to a HKS GTRS pretty soon. or as soon as funds allow.

Mods are the usual:

Z32 airflow meter

Nismo 555cc injectors

Full 3" exhaust

K&N pod

Dr Drift remapped stock ecu

HKS type S intercooler

R34 GTT highflow

Bosch 040 fuel pump

I think thats it.....

any comments?

[silver gts-t]

you want my advice??

ditch the dr drift ecu..

get a pfc

gain 10rwkw

how much have you spent on tuning with sam? and the chip itself?

i spent over $700 hours and hours altogether and all i had was a badly tuned car with a start up problem, an idle problem and detonation, he kept insisting it wasnt the sofware but the AFM, i plugged in the HKS fcon and probelm seemed to disappear??

now sam is an ok guy, never stated that he wouldnt fix it, but im in sydney and i couldnt wait for him to come back and forth..

in conclusion if your in melb maybe it aint so bad, but anywhere else dont bother!

not worth saving a few $$ get it done right the first time! not just a remapp that plays with timing and fuel etc

i paid almost $700 on tuning the Fcon alone and would gladly pay it again rarther than $300 on tuning the remap

<{POST_SNAPBACK}>

thanks for your ideas.

I didn't go the pfc as i was hoping that it would be cheaper to get it remapped - this was more than a year ago.

I do have a few problems with the tune but Sam says he will fix them with out any extra cost, so i don't have a problem with that.

If i was to get a PFC now it would obviously be like paying twice for the same thing, so i will stick with the remap.

He's got new laptop tuning software now, so he says it far easier to tune than before, he's promised to have another look to see if theres any improvements to be had.

I don't think a PFC can gain more power than a remap, its all in the tune and my a/f ratios are at a level i consider safe. There's nothing wrong with remaps themselves - just think of the Mines jap ecu's.

Cheers.

[silver gts-t]

mine's arnt the best example of a remap, and sam used his new software on my car.. no one could figure out the probelm, not even the software designer..

its up to you what you do in the end how much u can afford etc,,

if you managed to get a year out of the remap then cut your loses...

really!!!!!!!!!!!1 think about it! also remember that even if you get a pfc, ap engineering fc are in demand and a second hand one you could always sell easily in the end

[silver gts-t]

u tried turning the boost down??

the graph looks mega rich!

and i dont thing a pfc will give u that much

look for about 230ish
