GTR Mods - What next?

[BoOsTeD_RB26]

Hey all,

As topic says, what do you think should be next. Budget currently is about $800. Mods now are a turbo back exhaust, avc-r boost controller and k&n pods.

I was thinking an S-AFC for around $512 from nengun delivered. If i did this how much more power could I expect?

Thanks

Save for a PowerFC.

The FC + AVC-R is THE plug and play performance combo.

The hand controller is a fancy bauble you might want if you got ~$350 not doing anything.

Adjustable cam gears no doubt. Best mod for that money no question.

Generally power FC want be worth it unless you are looking to change Turbos etc.

yeh I have cam gears in mind, and I might go with the cam gears and the S-AFC. I do realise that the power fc is much better because you can adjust fuel as well as ignition, but i simply do not have the funds.

What sorta power increase would we be looking at?

do the SAFC and cams

I got my SAFC today and ordering my cams tomorrow.

sent you a PM

I will tell you saturday after I have dialed mine in.

I have just fitted them this week and will be putting it on the dyno Fri/Sat to set it up properly. I have boost up, turbo back exhaust, pods, and now the cam gears. Should be pretty similar to yours. Will let you know.

orrite sweet......make sure u lemme know

what kinda power u got now?

[Silver-Arrowz]

Save for the power FC, it's really worth it! Midrange power is heaps now, and distances between corners seem so short. Why waste money hooking up and tuning an afc when the power fc is da bomb??? If you can afford a gtr, I'm sure you can afford a power fc. In the end you'll probably end up getting one anyway.

If you really want to spend the money now, suspension. Swaybars really help the R turn in better, and stops bodyroll. 1470kg isn't exactly light.

Will let you know as soon as I do.

The other day we had 204rwkw but that was with it leaning out like crazy at the top end and with 13 odd pound. I have just today replaced the AFM which were stuffed and it has picked up heaps.

Silver-Arrows: what kind of performance gains did you get?....the suspension has already been done by the way. the mods i listed were only the mods associated with the power of the car.

how much would a power fc set me back....but just the FC....not hand controller...perhaps i will consider it but i dunno..have to see.

an additional odd $700 seems alot for just the fc.....what are the benefits of the fc?

either way...im definately going to get the cam gears

[Silver-Arrowz]

The FC i brought was second hand from Nengun. It was about 1300, but an additional 300 for the hand controller.

I got it tuned, but they tuned it at only 0.5 bar boost. It made a lame 160kw on all 4 wheels. The tuner selected the option of boost controller kit to on, which I don't have. That's why boost was only 0.5 bar. I fixed this today and it's running at 1 bar boost. Don't know how much power, but trust me, your brakes are going to need upgrading.

[BoOsTeD_RB26]

yeh brakes will be a bit of a worry :)

also..was there much difference in performance from 1bar/stock ecu to 1bar/powerfc?

Oh yeah!!!

I love the way the car pulls away now. Before it didn't have much midrange punch. Now it just pulls away and leaves me grinning like an idiot. People give me funny looks after I've stopped and try to take in what just happened.

[BoOsTeD_RB26]

hahahaha...thats what I want to hear

has anyone here fitted an S-AFC to their gtr....if so what was the performance gain like?

surely an S-AFC and adjustable cam gears would give some wicked mid range?

Silver-Arrows: have you got any other mods like Cam gears?

EDIT: with the sort of power you'd be making with these sorts of mods...would the ceramic wheels in the turbos be a problem? (last long?)....keep in mind only running 1bar.

[Silver-Arrowz]

Little. BOV's, air filters, cat back exhaust, thincker FMIC, bigger radiator, oil cooler. Oh, I've put cable straps around the intercooler piping. They expand under load so this stops it from expanding, and spools up better. It helps. $2 for a stack of cable ties, can't complain about cost there.

Should not be a problem if you stay 1 bar or under.

[BoOsTeD_RB26]

you serious about those cable ties....u mean them lil plastic ones you can get at the hardware?

feckin hell.....talk about cheap mod

[400HP]

Although I believe the powerFC is a very good ECU replacement (and I was amazed at the number of options of tuning it had when my friend fired his up for the first time the other nite) I wonder how much bang for bucks it has when running the ceramic standard turbos.

I was in exact position about 3 days ago choosing between powerFC and SAFC and I got the SAFC cos I thuoght it would do almost (obviously not AS good) a job but saved around $1200 or so from a second hand powerFC. With $1200 you can do quite a lot of other shit and I'm intending to spend it on cam gears + front pipes + dump pipes.

But its all up to you.... when it comes time to get bigger turbos I'll get a powerFC then. In terms of pure power the cam gears + SAFC are more bang for bucks... the powerFC allows you to do more later and adds efficiency throughout all tuning aspects giving more balance.. but at a price.

[BoOsTeD_RB26]

yeh very good point

shit...dunno what im gonna do now

S-AFC or Power FC.......gonna have to think about it

any other opinions?

Ok finished dynoing the car last night. Took ten runs to get it right with lots of tinkering in the mean time. Got 240rwkw in the end but most impressive of all is the way that the car feels now. Smoother, far more low down throttle responce. It has over 200kw at 4200rpm. It is very toey down low. Far more responsive and much nicer to drive. It feels heaps smoother and easier to drive off boost (not that it was difficult b4 but it is way different now).

So BoOsTed go for it. It is a big difference. Well worth it. Just take your time and set them up correctly. Every car is different and needs slightly different settings.
