What Mods Next?and Dyno?

[cliff25gtst]

hi guys how are you all going.

just need your opinions and help please?

well i have just got my front mount and dump pipe on my r33 gtst.

i also have an air pod,cat back exhaust adn boost controller running 12 psi. i am just wondering wat i should be doing next?? should i upgrade my ecu or is there anything else that i can do that doesnt cost as much as a new ecu??

should i upgrade my fuel pump?

and also i am after a dyno tune and run and i live in north east victoria and am wonderign if any of you guys know any good dyno tuners up this way at all?

your help would be appreciated. thanks

[cliff25gtst]

can anyone help out at all

[Devils_Advocate21]

Theres plenty of information in regards on what to do next depending on what power your aiming for, its all can be searched for.

Looking at your list, youve pretty much done all the stage 1 mods You can complete the rest of the exhaust with a highflow cat then move to aftermarket ecu and get a tune. From here then it gets expensive with turbo injectors fuel pump brakes suspension and the list can go on from there, best to look in the search function for those. Other than that best to ask that question on tuners in the victorian section they may best help you out about that information

Cheers

fuel pump - yes upgrade

ecu - yes, good gains to be had. stock ecu can't be 'tuned' must be remapped. Very few peopel remap r33 ecus.

I'm working on a new project atm - r33 ecu retunes. Stay tuned - I might release it (after I get my turbo).

[cliff25gtst]

yeh i think i will buy a new fuel pump next and then i will go for a aftermarket ecu.

yeh remapping the 33 ecu.

so maybe i should look for a power fc do you think? thats the best going around isnt it? if i can find one as they aint mking thm anymore.

at the moment i am just focusing on keeping the standard turbo for the time being and i am just doing 1 upgrade at a time. sometime in the future i may go towards the high flow turbo option.

so fuel pump and ecu sounds the go hey

fuel pump for the cheaper side of things + you will have to do that in the future if changing turbo etc

also a front mount would be good

i have what u got + a front mount, fuel pressure regulator, fuel pump and a fuel cut defender and got over 200rwkw on the standard turbo with the fcd sorting out the r&r issues i had until i can get a full computer

yeh over 200 hey, thats all rite i would be happy with that.

yeh i have got a front mount intercooler. ok so a fuel pump and fuel pressure regulator, what kind would be the best to go for? how much?

should i have a fuel cut defender if running 12 psi?

[tek_01]

some people will say fuel pressure reg is not needed but i had already bought it so i put it on and allowed the workshop to bump up the fuel pressure a bit and play with the timing + the fuel cut defender for best results

i got a nismo fpr for i think just under 200 delivered from kudos ms, fuel pump i first had a gtr one but changed it to a walbro one which was much quiter. Again that was just under the 200 dollar mark delivered. If your planning on going over 250kw the walbro might start leaning out from what other people have experienced.

with the fcd i just used that because the car was running REALLY rich especially after trying to boost it past standard boost which meant power decreased so this fixed it. but obvioulsy a full computer like a power fc would be a better (but more expensive) option

[cliff25gtst]

yeh i think i am going to get a new fuel pump and then go for the power fc eventually because then if i have that then in the future if i decide to go more power i at least have the aftermarket ecu all ready

thanks for the help

[cliff25gtst]

i was just wondering ,

instead of me going out and buying a power fc could i use a safc or safc 2 for my setup as i aam only sticking with the standard turbo and the set up i have now and it is alot cheaper then getting a pfc.

so with my pod,full cat back exhaust with dump pipes,bc runs 12 psi, front mount would i be able to next just get a safc and a new fuel pump instead of the pfc??

and what about my afm? will it need an upgrade?

[Birnie]

You have an identical setup to what i used to have. (about 2 months ago)

FMIC/Pod/3inch zorst/12psi.

On that setup it felt pretty damn good.

My next upgrade (and i recommend your next) was the ECU !

The best mod ever....

It sucks about the cost but it;s the natural next step.

Do it!

The SAFC is only 25% (if that) of an ECU anyway and will cost you $500 to buy and tune.

..and after that, you'll remove it and replace with a full ECU anyway.

How would i know? cause that's exactly what i did (and probably others)

So you might save $1000 now but you'll just end up spending it later anyway and when you do, you'll be going Woohoo! why didn't i do this before !

Do a couple more overtime shifts/ a paper run/ (the wall hahaha). just find the cash, buy the ECU, watch it get tuned, feal the smile on your face as you watch it come alive on the dyno and bigger grin yet when you drive home.

[Birnie]

Above post refers to no change to AFM or fuel pump and getting 194rwkws from a Hitman tune in Penrith. (some see a tad more)

Fuel pump and AFM is one of my next mods but I've upgraded turbo too so don't worry about those yet until you do the same.

haha yeh ecu would be much better but yeh it is a pitty bout the extra cost, i was thinking about the safc cause i was just thinking of keeping this setup and not upgrading my turbo or anything. thats the reason i was thinking safc not ecu, did you ever tune the safc and the new ecu with the setup the same as mine?

if so what was the differance in the gains. i know what your saying tho, and yeh knowing me like alot of the other guys on here that i hear them say, the standard turbo and all if fine, but then after a few months they start searching for more power wanting more power, haha.

[cliff25gtst]

still stock afm and fuel pump to.

so you dont think i should need to change fuel pump for this tune??

oh yeh and also fuel cut defender? should i have one as i dont.

194 from this set up, i would be happy with something around that mark

Just to be clear (cause i often leave bits out)

My setup was the same as in same standard turbo too.

Your car is basically the same as mine minus the Power FC. and that made 194kws.

Have you drivin a car with that power? It's impressive stuff.

It doens't sound much as there are so many high powred cars on here but they all probably went thru the same as you and I.

I can't comment much on the SAFC but i was on 10psi with no FMIC.

The after tune ride home didn't feal that different.

It did feal better but it was more of a shrug the shoulders and yeah, it's better i guess type fealing.

Putting in the new POwer FC without it being tuned felt like an SAFCx10 !

and better again after the tune.

I can see in you responses there is the 'trying to save a buck' fealing in there and I'm the worst for it if (if you can find my response to GTR fuel pumps you'll see)

...but just dump the SAFC idea altogether man, you won't regret it

[Birnie]

still stock afm and fuel pump to.

so you dont think i should need to change fuel pump for this tune??

oh yeh and also fuel cut defender? should i have one as i dont.

194 from this set up, i would be happy with something around that mark

for 194ish, no need for pump/AFM/turbo upgrade

No need for fuel cut defender if Power FC or equivelant is used (SAFC i don't know)

$$$ saved everywhere so go get that ECU already

[cliff25gtst]

drop the safc altogether then, it would be the smart thing to do. i see where you are coming from

guess i will just have to start saving my pennys up for a pfc then,haha,

yeh so no need for a change of the standard fuel pump you say? well that wil save me up some money for the pfc then,

is there any other little things that i will be needing ?

any idea on your gains before and after the pfc was fitted?

[Birnie]

1 thing to get, power FC and tune

Personally, i'd stay on 12psi but you can go a tad higher if you want.

Some people go less to be even safer.

There's heaps of standard turbo results in this thread, happy reading...

k mate thanks heaps for your help hey,

really appreciate it. thanks

yeh i will have a look at the results now.

Hey Cliff,

I agree with Birnie.. Definately save up and get the pfc.. i had safc for a while as well.. it was ok for leaning out mixtures which are too rich for that little bit of power, but the pfc does a much better job and then you will defiantely think, why didn't i just get the pfc to start off with.

Most of the post in that link only show their peak power, which doesn't really show the potential of the pfc. Most of the time your peak power will stay the same or maybe get a bit more but the real performance gain in getting a pfc is in the drive. boost seems to come on quicker, the car revs more freely and smooth. the average power was heaps better than before the pfc was installed.

It will feel like a new car.

DEfinately worth getting the PFC. Also make sure you get a full tune and not just a power tune.

Good luck mate
