My car has no go, need some help

[hijaked]

hi how are you all.

my name is David, and i drive an 94 r33 skyline turbo

ive only had the car for a few months, so i havn't really got the chance to know it.

the other day i decided to drive my lazy self to melb (i live country east of melb), to the rajab dyno day. the result was 148.5 rwkw

the mods i have on the car are

fmic (it has no name)

it also has like a security door like mesh infront of it, something the previous owner put on

hks air filter

big jasma xhaust, im pretty sure its got a larger dump too

turbo smart boost controller (at 8, 12 psi) - it was at 12 on the run

turbo smart blow off valve

my car is running rich aswel, sometimes i hear a backfire on the down shifts.

to my surprise my friends r33 got 151.3 (with air filter, xhaust at 10psi)

i have been meaning to get my car tuned, but i live so far out.

any suggestions to what i should do?

any help would be much appreciated!!!

thanks a lot, fellas

change your o2 sensor and get an safc

i think u have some very low figures 4 wat u have running under the hood man, 148.krwkw for a turbo? thats pretty low man, u do need to get a tune

[hijaked]

hey SECUR1TY nices wheels.... oh and car too!

yea i can do the o2 sensor easy enough, and the piggy back is questionable.

are the safc's good? (assuming its all tuned right)

i have heard all over the place they are really good or very bad. i really cant afford a PowerFC too.

i also have another issue, its illegal for me to drive my car, i already have been done once by the boys in blue. however i was considered unlucky that day, because most r33 boys dont have too much trouble (im from vic by the way, on my P's)

so im even considering selling my car, so i want to prevent needing to put money into the car.

someone also suggested a fuel pump? yes , no?

anyways have a good day.

rgds, Dave

hey TracidTrax.

yea i know. ima country boy. i live 2 hours drive from anyone who knows what a car is, and possibly how to fix it.

i would get a tune sooner but its hard enough with travell and the fact i still have to go to skool.

how much do you think a tune up is going to cost me???

i know the dyno was poor, i will try to fix that figure!!!

cheers, Dave

my r33 has made 201.9kw with the following mods:

- no name dump, apexi front pipe, apexi cat back

- k&n panel filter

- avc-r @ 10psi

- safc II

- o2 sensor replaced

I got it tuned at UniGroup engineering. Heres a link to the dynograph. I reckon the figure is a bit high but it does show how the safc & proper tuning helped out :

thanks mate.

safc's are good if you go to the right place that will give you a safe tune, i.e. still run a LITTLE rich.

[Ruffels]

lol dave i dont have an exaust.. just the pod and 10psi.. 151.3 wasnt bad

im gonna get safc2 probably and exhaust and front mount... perhalps power fc.. who knows

fuel pump won't be the problem, but you may want to upgrade for reliability reasons (stock pump can fail).

also if it's running rich, safe bet it's not the fuel pump. It's always good to run a little rich, as it's good insurance against burning valves..

did the workshop who dyno'd the car comment on a low reading? some dyno's can be fairly conservative. and if it's a no-name front mount, chances are it's a hybrid copy or something, which are very poor quality coolers.

if your car has those mods, it will probably be in need of a tune. and maybe get a workshop to plug in consult port which will tell if o2 sensor is broke, or injectors are maxing out, or afm isnt' working or whatever.

also, don't run more than 12psi on stock turbo!

hope this helps! i mean, how does the car feel on the road? does it feel like it should have more power? perhaps go to a couple of car dealerships and see what a stock r33 should feel like.

[Dush]

i donno man, i'm suggestion would be Power Fc, tube & fin cooler and maybe a coil pack...

ive heard nothing but praise from the hybrid copy coolers. ive even got one sitting in my room waiting to be installed.

hey guys

sorry with late replys.

i havnt really had the time to think about whats gonna happen with my car.

but something will be needed to be done.

ive driven a range of skylines with the same mods, and none of them feel the same. weird.

i would really love to have a PFC installed, but i have no money! which is a bum.

i was thikning about getting a safc, so someone can tune it right. do yous think that would be a good idea?

i had it dyno'd on a dyno day, so they werent too interested on the result or what was going on, but i was pretty dissapointed

the intercooler on my car, looks dodgy. however its restricted a lot by the mesh that sitting in front of it, had trouble finding the time to take the front bar off. is it hard to take the front bar off?? also what would you use to clean an intercooler?

when i want to 'boot' my car i prefer to do it in 8 psi than 12. it jsut feels better. however still empty, and boost comes on around 3.5 ish rpm

i apologise for the bad attempt to explain all this.

better go keep the teacher happy now

thanks fellas.

ps. ruffels you car is a piece of ass

i've been told that they flow very well, but don't cool well.
