Hello all,

I've just joined this excellent forum and would like a piece of advise if possible.

I've got a 99/V impreza turbo saloon which is completely standard and been kept in immaculate condition with full history. I'd like to take the bhp up slightly to 240 bhp but don't want to drastically change it's originality.

My question is can I get it mapped to 240bhp without changing the original exhaust/induction and if so where is the best place to have it done?

Thanks for your help, Jon.

 

do the pannel filter normally about £40 for adecent one, then in theory you may get 240 out of the standard exhaust, although you may need to put sports cats on, if you don't wanna go down the decat route

 

How much do you have to spend ?

Remap is certainly best bang for buck, although most folk fit decat/sports cat exhaust bits to make the most of the remap. will get you quite a bit more than 240bhp.

 

Thanks for the replies, i was hoping to spend around £300-£500. I'd prefer to keep the exhaust standard for originality but will get a performance panel filter to help induction.

Where is the best place for mapping, I live in south east London?

Cheers.

 

The panel filter thing has been debated many times. The mappers themselves and Prodrive say don't bother and keep the standard one, it won't make a difference to the performance. Save you £40 there.

If you only lose one cat the car will still pass an MOT (mine did) but it will help if you get it mapped. There is a group buy on for a £500 ecutek map on now, have a look. I can't comment on the quality of the bloke doing it since i have no experience of his work.

5t.

 

Jon,

welcome:

If you want to reach 240bhp and std ecutek remap of the ECU will most likely do it. BUT it'll cost you about 600 smackers. TBH It'd be much better if you did the exhaust THEN got the re-map. Very reliable 270ish then

Dump the standard exhaust! It's ****e! You don't have to have a big wideboy system. Plenty of discreet, but much more free flowing items out there. Go for a 2 and a half inch system with a sports cat in the Down pipe and all will be well.

Now onto money:

Backbox. I'd suggest the original Scooby design, not OTT at all. Circa £200
Centre section (resonated) about £120
Sports cat DP £299 (if you get the ninja one from scoobyworld, which you should!)
Oh and an uprated filter! (about £40)

A UK car will run a sports cat system without issue on SUL petrol, so you could just get the exhaust fitted and then run it whilst you save for a remap. That alone should get you to about 240.

A remap will really bring it alive though!

Avoid any nasty dawes devices or induction kits. The above is the safe way of doing it. Not cheap, but power never is!

 

Jon ,

I have MY00, It was fitted with the uprated 2.5" exhaust from subaru from new.

My first ever modification was Magnex decat down pipe (around £200).

I took it to Power engineering and it made 241bhp on their rollers, everything else was completly standard.

However I was in there for a remap and came out with over 280 bhp

I was soon addicted to getting more power, and still am

 

Getting MY07 mapped mid Feb by Mocom Racing near Harlow for £400.
Just fitted a Simota Racing Panel Filter from Scoobyparts £29 delivered.

 

thanks fot the tips,

Where can I get the subaru 2.5" backbox that sounds like the one for me?

 

SUBARU IMPREZA EXHAUST OFF CLASSIC SHAPE on eBay, also, Subaru, Car Parts, Cars, Parts Vehicles (end time 27-Jan-08 15:31:47 GMT)

This looks like the one I had

 

just pick up a 2nd hand prodrive backbox I got one for £90 I think they are about as discreet as you can get or at the moment there is a full prodrive performance pack on ebay for a 99 UK turbo, I think grade A subaru are listing it.

 

revolution 3" open neck downpipe
revolution 3" exhaust system from down-pipe back
walboro fuel pump(not really needed but might as well for 80 quid)
BRDevelopments remap, TEK 3
£900 ish the lot
265 - 275 bhp

as above, dont bother changing the panel filter , well, maybe for a new standard 1 , exhaust , ok,you don't need 3" , , 2.5 will be fine but the revolution is an awesome and IF you wanted more power 1 day then you've got the best exhaust already IMHO.

 

grade a have a full ppp kit on ebay at the moment,its at £250 at the moment,almost 240 bhp and keeps originality.

 

That prodive kit on ebay looks exactly what i'm after but is it as simple as just plug and play with the upgraded ecu? I thought you had to have your car individually mapped depending on setup?
