hey everybody i have a impreza turbo 2000 1997.
i wanted to know can my engine support these mods im goin to do and how much roughly will i be powering out.
the cars standard with a full nur spec r de catt.
i bought fmic,filter,walbro 255,440cc injectors with a apexi power fc.
havent put them in yet but some one said to me the pistons can melt if its standard is that load of bull, or not.
really confused need help.

Pistons will melt if the boost is high and there is not enough fuel. You have listed the fuelling mods that you are going to use, so as long as the APexi is mapped properly you will be alright, althought eh first 4 mods you have listed would be better suited to an uprated turbo.

Turbo_Tkk

so with all these mods i shoudl change the turbo also?
if so what turbo would you say and howmuch do you think i be pushing out without changing the turbo.
cheers

sorry forgot 2 add that i also have unequal length racing headers,still thinking if i should put it in the car is it worth it?will i get anything from it?

Well the turbo you have TD04 is only good up to 280bhp I think. So you wanna at least go for a TD05, which I think you can get for 200-300 quid. That way you will be comfortably over the 300bhp mark.

cheers for that, i shall start searchin for one rightaway

TD05 will be too laggy at that power, your better off getting either a VF28 if your not wanting to go over 320bhp or a VF35 or VF34 if you want to go upto 350bhp. All these are direct fit for your car

Also you'll definatly need a decat downpipe, and maybe some ported headers (depending on what power your wanting)

I found the best thing to do is get an idea of what BHP you want to get to and then work out what bits you need to mod to get there.

I'm sure you are aware, any turbo mods you need will require a remap or you will pretty much knacker your engine.

I have a my99 uk turbo and i will be addign the following to get to around 300bhp:

Sti8 tmic
vf35 turbo
decat downpipe through to backbox
jolly green monster remap.

NS04 thats a nice spec for a uk classic, not too much power so its crap on the road but more than enough to scare off more exotic machinery

You may need to upgrade your clutch also mate

cheers for that i was thinking more like over 300bhp if more why not?
i have a de-cat its a straight through to the box.
im going to start looking for the turbos,theses mods are just the start so i would want more bhp later on.
ye i do realise i need a re-map so im lookin for a apexi power fc and going to get it mapped once everything goes on,as in all together.

Turbo_Tkk

cant find any vf34-35 or to05 anywhere even on ebay???
wheres the best palce to look with a good price to?

I wouldnt think a TD05 would have terrible lag if it has the right supporting mods and is well mapped, but it wont be as responsive as a VF35 or the small TD04.....my spec is

VF35
STI 8 TMIC
Sard FPR
Walbro 255L
H&S Downpipe/Magnex full system fully decatted
Green panel filter
and all mapped with an apexi power FC and commander at 1.3-1.35bar

Its really good power on the road and the reliability of the car isnt compromised, the spool up and low down torque is excellent but it pulls much harder throughout the revs too, a VF35 is comfortable at the 330-340bhp mark but thats about its limit, however it will make for a very responsive and snappy impreza...

put it this way on the off chance today i had a run in with a lamborghini gallardo both 2nd gear out of a bend and to the top of 3rd he didnt really get anywhere, im sure if we had have kept on he would have ate me but power to weight of a 330bhp classic with 4wd will give alot of supercars a fright upto the tonne.....(im not condoning road racing btw, this was on a private road )

Turbo_Tkk

lol sounds good
i am having a look at all my options re upgrading the turbo
i want spanny power with a very noticable difference.was thinkin of sumwer of the region of 350bhp?


p.s. im lookin for a apexi everywer geting messed about so much,bought one on ebay and turned out to be a time waster seems he didnt have it himself. so the search is still on!!! lol

silent running

I've had a TD04 (originally), a VF35 and a TD05-16G. Each step you go gets you a slightly higher spool up point and extends the reach further into the upper rev range. However, I'd say the big difference is between the TD04 and the VF35 - the '04 was gutless up in the revs which the VF wasn't. The TD05 is more like the VF35 but with more oomph. IMHO there is very little in it as far as spool up goes between VF35 and TD05. Just depends on whether you're after low 300's (VF35) or mid 300's (TD05). The TD05 16G is by no stretch of the imagination a 'laggy' turbo.

Turbo_Tkk

oh cheers for dat cleared tings out for me lol
i am goin to look for a td05 then i am after mid 300.
im jus taking my time and looking around.

The VF35 will do mid 300s with the right set up.

Really, for both the VF35 and TD05, you'll want bigger injectors and a better intercooler to get the best out of them.

my car is pretty mucht he same as NS04's but im runnign a vf34, now running 340bhp + a couple lol

Turbo_Tkk

called up a few garages and that,been told that my car wont b able to hack the power being a turbo 2000. but i seen peps on the forum with more pwoer froma turbo 2000????? ne help chaps

Tidgy

350 is about the limit you'll get away with, 330 is prob safe side, 340 is perhaps a tad risky, but safe with right supporting mods, like oil cooler, set of gauges to keep eye on things, etc etc

Turbo_Tkk

allready gt a boast gauge and also a feul air ratio one 2.
mmmmmmm 340 shud b ok gta see if i could find the right parts. i shud ahve got a jdm impreza.

Tidgy

lol, tbh once you get to that stage start point makes no diff, jdm would have cost you more in the first place anyway

if its a healthy engine and is mapped det free with all the right supporting mods and not revved like a bike or abused you could be fine at 350bhp

alot of turbo 2000's are running that sort of power just depends on the factors ive mentioned above...out of all those things your clutch will prob let go before anything else

New_scooby_04

iTrader: (4)

Obviously age and condition of the car, together with intended useage, are relevant factors, but a fit UK turbo will be reliable at the mid 300s with appropriate supporting mods and 1st class mapping. Some have even run at around 400bhp and not had a failure. I ran 320/320 for two years on the std MY99 injectors and intercooling without issue, as have many.

Your gearbox may be a different matter!

Some sound advice there.

Just go for the TD05 16g though, IMO.
