Got a nice green panel filter fitted when I had the car serviced...
Had my MOT this week, passed with no problem so am now in the process of having a decat frontpipe + middle section fitted.

What bhp would give to a std UK turbo running normal boost?...

What can I do to the car next to give it some more grunt?...

Electronic Boost Controller?...

What would people suggest next?

Matt.

hoses, fuel pump, headers and remap

:D

Tek 2

Without a doubt :D

cinders 16 December 2003 03:20 PM

Whats a TEK2?.......

Someone mentioned buying a 2nd hand electronic boost controller and increasing it from 0.9 to 1.1 / 1.2?........

stanmo 16 December 2003 03:46 PM

A Tek 2 is a remap of your existing ECU ('99 onwards)to take advantage of a freer flowing exhaust, usually allowing higher boost than standard (which is 1.0 Bar, iirc).

cinders 16 December 2003 03:49 PM

My cars a MY98 can you get a TEK2 for that and how much does it cost?...

Upgrade the fuel pump and ecuTEK.

The ecuTEK is your ECU/EMS reprogammed to a map specific for your car. Actually that seems to vary from where you go. Some pleaces seem to put a generic map that is close to your car set up then test that. Other places actually map the ECU to your car by doing several tests and runs to make sure that everything is tuned to your car.

The fuel pump will avoid your car getting starved of fuel and the remap is the best way to avoid your car going bang (as long as it is mapped properly).

ECUTek is for 99-00 cars only, so it's not an option on your car I'm afraid.

You don't need to touch the ECU for ages. My 97 runs 344bhp on the OEM ECU and hoping for more in the New Year. I'm looking to see just what the OEM is capable of.

Personally I don't think a fuel pump is always necessary with a TD04 unless your OEM one is weak. It can't run enough boost to worry the OEM pump IMHO. I fitted an uprated pump and even at 1.2 bar on the TD04 the car was running way too rich.

Boost controller is a good idea but I personally wouldn't run much over 1.2 bar on the TD04(you'd also need a FCD to run boost this high) and I'd suggest a Knocklink also for sure.
THEN once you are running higher boost I would assess the need for a fuel pump based on your AFRs and any knock activity.

High flow inlet pipes are also an excellent (if expensive) mod on these cars.

For power over 280bhp you'd realistically want to look at replacing the turbo with something a bit bigger. TD05 is flavour of the moment but there are alternatives, then I would say a fuel pump will definately be needed.

Most important make sure the car is serviced regularly using quality oils/parts. A car is only as good as its last service ;)

If you want any info, drop me a mail.

Thanks for the information Rich! Thats great!

I think I'm going to get both a knocklink and AFR (I guess thats air/fuel ratio meter - is that the "Dawes" device people talk about?)

After that I'll get myself an electronic boost controller and see how much I can push it.

I'd be happy with 280bhp from my Impreza. I don't want to spend stupid money on it.

u dont need to do the fuel pump m8 on a uk car :rolleyes:

mr smash 16 December 2003 09:19 PM

why not on a uk car..does that meen u would on a import?

RICH WILD 17 December 2003 09:36 AM

For a moderate power hike, I'd agree the fuel pump is probably more than adequate on an import OR a UK car.

As far as old/ high mileage cars are concerned a fuel pump is ADVISEABLE but not always NEEDED.

For a decent high power car, an uprated fuel pump is ESSENTIAL.


Cinders,

If your aim is 280, as I said in my above post you are more than likely OK on the OEM pump if it is at full strength.

oh, and as Kevin stanton points out, intercooler hoses are a good idea. The OEM ones are crap.

I'd disagree with him on headers at this early stage though on a classic engine. In my experience, with the OEM ECU retained I have seen a number of cars (including one of my own) gain nice chunks of top end power but lose quite a bit of response and midrange. I know other also with different experiences though, so headers may be a bit of a gamble on a lightly tuned car.

Re AFR meters there are several. Link do one (Lambdalink) and so do Dawes. Lumenition do one too which is fairly good.

Rich
