Dilema

[Lachlan33]

Hey guys.

Ok so ive established that the Justjap JJR intercoolers are good and worth the money ($550 for a type 2 kit)

My goal is:

FMIC + Exhaust then crank up the boost.

Good idea?

OK lets say it is

I completed my tax return today, should be getting about $900.

Car is almost stock, except for a POD and BOV.

My Dillema is, do I go for the exhaust or Intercooler or something else.

Can only afford one at this time.

The Exhaust i had my eye on was the X-Force 3.5" Turbo Back system ($799 for mld steel, $950 for stainless steel)

The Intercooler kit im also looking at is the JJR Type 2 Intercooler kit.

So if I could get peoples thoughts on:

*Zorst, FMIC or other

*What effects will each have on my car

*Any other sugestions you feel are relevant

Thanks guys

Step 1: 3" Turbo Back Exhaust with split Dump...

FMIC on its own wont gain you much if anything at all...

Whats this split dump buisness? (don't know what that means )

Also would there be much difference between a 3" and a 3.5" system?

X-Force does both the 3" and 3.5" turbo back.

Im thinking X-Force mainly because I had an X-Force cat back on my previous car and it sounded great.

do a search on split dump pipe and you will see... the split dump seperates the wastegate gas then rejoins about 40cm down the dump... makes big difference to a single bell dump..

i wouldn't go anything bigger then 3" on the exhaust... unless ur running twin turbo or have 400+rw/kw

good way to spend $900 in my opinion:

- full turbo-back exhaust

- turbotech boost controller set to about 10psi

- oil and sparkies changed

- 1 hour on dyno to adjust the timing

you want a 3" exhaust.. no bigger, no smaller...

probalby the greatest mod that one could EVER do to a turbocharged vehicle...

how can you dyno tune a stock ecu though? didn't think there would be much gain to be had.

[eMsta]

turbo back exhaust, then front mount followed by boost and then powerfc it to get maxium bang for buck - but its gonna cost more than 900

Edit: X-force has a nice rumble to it, depends on what you want - quiet or loud.

I want loud...ish.

As in, legal and not overly droney.

Does anyone know if the X-Force has this split dump that was mentioned? If not, any other reccomendations on a full turbo back system for $900 or less.

Also is it worth paying more for stainless steel? Ive heard mild steel is more than fine for many years.

x-force don't do split dump pipes.

3" is fine, 3.5" is also fine. you won't notice much difference. i have the 3.5". i ordered the 3" and they sent a 3.5", so i put that on. hits on the body a bit more than a 3" would.

[mad082]

and most systems are going to be louder than what is legal.

[Lachlan33]

lol ok.

Well how much of a difference does a split dumppipe make?

And how much of a difference will the Xforce turbo back make over the stock exhaust?

More power?

[eMsta]

x force turbo back - maybe around 10rwkws at max?

you can get the split dump front from batmbl (hes a member on these forums), and then just get the cat back from x-force and attach it to whatever cat you got running

[Munna1]

have a look in at the tuning guide from the site in my sig this is the order that most people do things in and for good reason.

cheers

thats going to work out much more expensive than the full x-force kit, and not give much of a power difference.

[Lachlan33]

Ok well theres the Xforce turbo back

$799 for Mild Steel

$950 for Stainless steel

Theres also the JJR Split dump for $125

Whats the difference between a 'front pipe' and a 'dump pipe' ??

Does a split dump make a big difference?

Again what sort of difference would I notice going from stock to the full Xforce turbo back

And what difference ontop of that would I notice if there was a split dump?

[mad082]

no you wouldn't notice the difference between a split dump and a bell mouth dump.

the dump pipe is the pipe off the turbo. the front pipe goes from the dump pipe to the turbo. the x-force pipe is a 1 piece pipe. it has both in the front pipe.

the jjr dump pipe also requires a front pipe.

[Lachlan33]

Ok so in summary you reccomend I just get the full Xforce turbo back system?

Thanks for the help guys.

yes

[WazR32GTSt]

how can you dyno tune a stock ecu though? didn't think there would be much gain to be had.

i didn't sasy "dyno tune" i said time on the dyno to adjust timing

a dyno is just rollers so that the car can be driven as on the street but still monitored (eg listening for pinging)

with the car strapped to the dyno the mechanic can see how the engine runs (eg is it making the right amount of power?) and adjust the CAS to change the base timing (give it more power!)

this usually costs around $100-110 depending on the workshop and is highly recommended

i agree with mad082. get an x-force turbo back system, get a bleed valve and set it to 8-9psi, maybe even 10. the standard side mount shud support this, but if u want to be more safe and economical, buy a gtt side mount. after this u shud pick up at least 20-30kws at the wheels
