The Impreza picture and discussion thread

[jay70]

Hmm the past few posts have scared me, mine is a 2000/2001 registered classic with a decat (not remapped):nono:

#

As i mentioned in an earlier post Liam, the JECS ecus do tend to take to a decat better than the later Denso ecus in the newage cars. If you're worried then get a wideband shoved up its arse to see how its fueling either via a dyno or a mapper.

what is worryig me is the fact it had no lambda sensor? Surely it should have one? Does anyone know what the stabdard cat looks like?

 

[trails]

Yes i am Trails for all my sins...lol

Then I've also sinned...come say hello on my project thread

 

[MarcoB]

Bought an SWRD 255 fuel pump off scoobynet looking for an ESL so i can get it mapped asap, i don't want it to go bang.

Reading a bit more into them looks like the best option.

you must have had a lamdba sensor...some JDM cars have them relocated to the headers...

this is an early DP

For the price ESLs go for you would be better off buying it new IMO.

 

[imprezaworks]

How much are the esl's new? I'm sure there's one on scoobynet, wants £200

I know it will have had one at some point i just dont understand why the decat wouldnt have a lambda hole welded in. Wont know for certain what it looks like until i get it on a ramp next week.

Thinking of andy forrest to remap it as well.

 

[imprezaworks]

He's a top guy to map

 

[MarcoB]

Bought these on the bay - genuine rotas, not a brand ***** so these will do. Will need to get some matching centre caps.

 

[imprezaworks]

Quite like them mate. Good price?

Couple more just of the scoob;

That gives me a hardon. My perfect Impreza.

 

[imprezaworks]

Can't decide wether to swap my 3" japspeed (decatted) to a 2.5 hayward and Scott (decatted). Tough times...

 

[theduck]

Look similar to my prodrive wheels marco, good choice.

 

[MarcoB]

Not a bad price at all, I think they will go better with the blue than gold.

Is the 3 inch too loud?

That 1 above is perfect!

Why would you do that?

Surely the 3" is better for performance gains. Plus if you're OCD you'll also require another map if not a AFR at the least. Blitz I think 'sound' the best for the Subaru but are a little on the loud side. I think they are only 2.75" though?

 

[imprezaworks]

I've spoken to the mapper, it's fine, going the other way I think would be slightly riskier. The exhaust is fine noise wise, not too loud etc but I fancy experimenting with a 2.5. General thoughts are a 2.5 is fine upto 350 ish then a 3" is more suitable.

No not too loud at all, well in the car atleast.

 

[Midnight]

I don't see the point at all...

Never been a fan of the H&S let alone going from an upgraded 3".

 

[Ray Gin]

It's all about the 5"

 

[imprezaworks]

Tbh if I thought it was a 'great' idea I would have done it by now.

 

[imprezaworks]

It's all about the 5"

No one likes a show off

 

[Ray Gin]

Haha

The Blitz nur-spec comes in Spec R and Spec S...The 'R comes as a full 3inch system and the 'S is rear silencer only that tapers down to 2.5 to marry to a stock center section.....Look great, well made but fecking loud!

 

[Midnight]

I thought the R also tapered down to 2.75"?

There was a huge thread about them not being a genuine 3"
system. Doubt it makes a huge difference on the road though...

 

[imprezaworks]

I don't want anything mega loud, I know the blitz is

You don't need to switch to a 2.5 system if you want a quiet exhaust, Cobra make a quiet-ish exhaust for trackdays tho not cheap. I swapped out a nur-spec on my last Impreza for a 3inch slip jointed Magnex with a rear silencer that looked like a stock prodrive silencer, sounded almost stock when driving normally(no cabin drone). Coupled with RCM headers on full chat it sounded awesome.

 

[imprezaworks]

It's not that I want quieter as mine is fine. I do think the 3" gives a different tone to my previous impreza's which had 2.5 systems

 

[Welsh.Dan]

I had Hayward and Scott system on my classic. That was 3" turbo back decat and sounded absolutely superb.... Not too loud or garish. Loved it!

 

[imprezaworks]

I had the 2.5 on a uk and sounded brilliant. I'm tempted as it's only £140 including the decat downpipe

 

[Welsh.Dan]

I had the biggest bargain I've ever had with that exhaust system...... £231 delivered!! Looked about 5 months old.
The back box is 300 on it's own

When I bought it the whole system was almost a grand. Now the same systems cheaper at about 650. I'd recommend it.

 

[imprezaworks]

Bargain.

 

[yeecup]

I had full h&s system on my last classic with the prodrive style backbox, sounded awesome but not chavy loud.

 

[Herr Flick]

I'm getting the itch again

 

[yeecup]

Lol. Keep seeing a mint sonic blue uk turbo parked near me, always spotless, god I want it! Pointed it out to my wife she was like your car is much nicer. I just love classic scoobs it's a serious problem. I will have another

 

[yeecup]

In fact I took a pic of it Needs to lose rear tints but it's spotless, spotted whiteline droplinks and racebox exhaust. I need help

 

[MarcoB]

Arghh, car got delivered today and it is not exactly what I was expecting has a major fuel cut off on WOT and the bodywork is pretty shabby. The lambda sensor is in the decat down pipe but it is not connected to anything? :/ Found a plug on the nearside wing that needs connecting to something and a vacuum hose that has been cut and blocked up. Can see this being sold very quickly.

 

[imprezaworks]

Pay your money and take the risk. These can be expensive.......
