Time for a power upgrade :wassup:

after driving around for about 4 months in this beast of a car!i am addicted to Skylines more then my seven... although my seven is not standard but i feel the need of upgrade and i have been sorta getting over the rotary and now addicted to the RB Twin Cam powerd engine!

the list just goes on for great performance!!!!!

GCG Hi Flow Turbo

GTR Fuel Pump and Injecters

Intercooler with pluming to suit 600*300*76

Apexi Power FC

GTR Cams

dump pipe

hi flow cat

aftermarket exhaust with aftermarket muffler.

std gbox.

the car has done 96,000klms and is running like a beughty!

[cameron]

so whats the question ?

[Serious-Seven]

so whats the question ?

oh i was just wondering is this any good ?

also , dyno figures and some qtr mile times ( not exact times offcourse) would be good to know running this car on 225 tyres ( G grid.)

[BHDave]

Looks good to me. Has enough bits for an easy 220rwkw plus depending on the highflow and tune.

Hope the suspension, braking and tyres have been sorted too

[cameron]

And around a mid to low 12 sec quater mile maby better with really good tires (nitto555r's)

As BHDave you'll need good suspension set up to get the power to the ground.

Happy Modding

[Serious-Seven]

im thinking of going whiteline setup second hand and spend around 500bux on suspension. brakes i will replace with gtr brakes from an r32.

hopefully all this will be exciting to see!

thanks

[cameron]

let us know the results !

[Serious-Seven]

No problems,

would anyone want to tell me on anything im missing or something better to do ?

[BHDave]

I'd just be getting a quick dyno run done to check the mixtures and the timing are ok and if so then leave it alone for a while til you sort suspension. Then you'll know what power it makes and know it's safe. PLus you already seem happy with the way it drives.

Brakes are very good standard, just get some decent pads, I wont recommend brands cos there always seem to be arguements. I use rb74s.

The power delivery on RB engines are allot differnt from my Seven thats why i am chosing to modify this car too.

cant wait!

If you start making over 200rwkw and use a set of grippy tyres make sure you hire a car trailer and a mate to tow the car home from the drags. The rb20t g/box's don't like grippy tyres. Standardish street tyres are fine, iits only soon as you start dropping big burnouts on Nitto's then launching you will break the box.

[Serious-Seven]

Thanks buddy... hopefully i will NOT blow my gbox! hehehe.

A power fc was never made for the rb20 . You'll have to find a Ap Engineering one and they arnt easy to find trust me. if you do find one be prepared to forlk out some serious cash, coz you'll need a z32 afm aswell to make decent power with a good tuner. I dont want to put a damperner or anything. Just letting you know. I'm going for 200-220 out of mine. atm i'm at 140rwkw.

Well there seems to be not such an issue with buying Pfcs new, but 2nd hand they are pretty rare and normally sell for more then a new R33 PFc.

FYI, i just paid $1150 for the PFc, $300 for the AFM, and $400 for the hand controller... so is certainly not cheap like an S13 of R33

[Sydneykid]

Clutch, there is no clutch upgrade on the list and it will need one. You can get the standard ECU tuned in real time on R32's. So if you can't find a Power FC, then it's a good fall back. I haven't had to change the AFM up to 225 rwkw, you may not need to do it. Some engines do, some don't. I have no idea why, I put it down to "engines are different".

Hope that helps

How do re-mapped ECUs go with different AFMs and bigger injectors...i suspect they are fine?

Whilst its great that the std ECU can be re-mapped, i had trouble finding a tuner that could do it at a dollar figure that sounded reasonable. I was quoted by around $800 by one shop, though im comfortable at that price, with that workshop it woudl be a great tune. Capable tuner seem to charge about $300 less for a PFC tune.

Hi Roy, don't you ever sleep? :ghost:

One of my famous "rules of thumb", if I change the AFM then the standard ECU is past it. A small upgrade in injectors is OK, but doubling them to 550 cc's is not a SMALL upgrade. You made the right choice technically, relax and get on with it.

As to price, ~$800 seems to be the going rate for a real time tune and chip burn on a standard ECU. Trouble is it is ~$800 everytime you make a change. That's why the Power FC was a good choice financially , so relax and get on with it.

Next time I am in Mexico for a race meeting it's your

Yeh time to sleep, already had a few shouts tonight so maybe a sleep in is on the cards...my place is already a halfway house for sydneysiders, so anytime

AP PowerFC's can be had from http://www.nengun.com/ and http://www.greenline.jp/

I doubt he's got 220rwkw...

I'm guessing around the 190-200 mark. I've yet to see a RB20 with more than 210rwkw

knowing what amount of boost he's running would be good as well.
