Craig Mac and ex Gumball car has knocklink fitted[]

Sorry that i didn't know all scoobies got knock sensor fitted but you learn something new everyday[:S]

TD 05 18G turbo is a really good turbo,just ask Higgy as he has one but soon to be changed to a GT series.

You don't really need a CAI but they do sound good and there are gains to be made.

But do you follow a tried and tested route or try something different for a change?

Just go for it Chris but best thing to do is go for a ride/drive with other folks cars.

Is that an offer Peter for a shot in your lovely car.

I promise not to blow the coil pack this time.

[fai17]

 I touch goats...i'm off work the now

[mctwistuk]

cheers Peter,

i am at work the now otherwise i would have popped across.

I touch goats.

Think i will be getting the knocklink as a precaution.

The 18g i am confident is what i am going to go for.

just need to decide on CAI or your extra large mushroom the size of belgium (i think it was described as by Steven).

 

[fai17]

There is absolutely nothing with your list of mods...

18g turbo

STI pink injectors

Walbro fuel pump

APS CAI 65mm

knocklink

lambdalink

defi BF oil pressure, oil temperature and boost gauges

decatted up pipe

boost controller

ECUTEK remap hopefully by the master Mr Andy F

But you'll need a full decat exhaust[]

Hi Chris,

I am running almst exactly the same mods as yourself and you'll see by the signature below that it'll easily get you the 330bhp you're after.  I'm running an STi TMIC and a de-cat pipe.

What I will say though is that with a decat and the APS CAI, the car will be VERY, VERY loud.  I thought it would be a good thing (and secretly I still do [] ) but I'm pretty sure the neighbours don't agree!![]  Something worth bearing in mind...

Good luck with whatever you go for anyway mate.

 

A decat doesn't make your car very loud..it just depend what make you exhaust is..

I wanted me exhaust quiet so Meercat has made my backbox huge

[mctwistuk]

I am waiting for feedback on the sportcat downpipe as i would like to go this route.  Not much difference in flow from decat and will keep me legal.  Yeah i know big girls blouse.

It also keeps you legal for both MOT and roadside emissions testing. If you want, I could try and scan the pages of Scoobymag that had the Andy F article and post them up. The thing with the turbo is that assuming you don't want any more power in the future (and the 5 Speed box struggles with too much more anyway), then you are better to go for a turbo that isn't oversized and giving too much lag.

I believe it was Clarkson who coined the "the size of belgium" phrase. But I like to use it.

[drb5]

Lol, i doubt very much you will find the 18G to be "laggy". Jesus, how many peeps are there with 20G's on their 2 litres!?

 

If there is something i hate doing, is changing too many bits, over and over again. Stick to one thing that will do the whole job and don't scrimp on it. There is ALWAYS a chance you will go further in the future...

That's nothing to worry about at all Peter. []

We're ALL still learning, ALL the time. [H]

Thanks matey.

STI Bandit has already kindly scanned the article in question for me.

I am aiming for similar power with the wife's WRX (currently PPP) or slightly more and my planned mod's were

H&S sports cat downpipe, replacing the primary/pre-cat in the up-pipe witha straight through section (the last cat has already been removed as part of the PPP), an Andy-F modified TD04 (excellent spool-up giving superb in-gear times), a newage STi intercooler and finally a remap by the affore-mentioned man. A STi fuel-pump and injectors will also be sourced (A fuel pump was sourced but ended up on my GT-.

I read an article in the last ScoobyMag by Andy that had been his WRX based on a similar spec, and IIRC, it was producing approx 320bhp and was giving some startling performance figures.

That would be my ideal set up. Sports Cats are braw ( if they are good enough for the Litchfield Type 25 then they are good enough for me). The hydrid TD04 is also an immense piece of kit that will easily yield 320 but spool up VERY quickly !  Speak to Bing as he has done something very similiar to what you have planned.

I would do it if I were you........WRXRich on SN was making over 400bhp with it on his WRX. This was using a TSL Thundercat. I just passed my MOT with flying colours with decatted up-pipe and centre. I used to have a decatted downpipe from H&S. I do not notice any difference between the two. Strangely I do get more pops with the TSL though ?!

A friend of mine has a 2002 WRX, it's got a Mongoose exhaust system, H&S cat downpipe and up-pipe. STI 8 Intercooler and K&N panel filter. He got an Ecutek remap from Andy F, and got 285bhp and similar torque.

His next step on Andy's advice is a modded TD04 and mapped again. 320bhp was quoted.

Probably what your looking for.

David

 

Meant to add he took it for it's MOT last week, and it just scrapped through the emissions.

[mctwistuk]

am surprised it only just passed.

with the sportcats it should have sailed through

[drb5]

From hearing a few stories, you need to get them MEGA hot, before they'll get through. I doubt it was heated up enough to "scrape" through.

[mctwistuk]

so would fitting an STI topmount intercooler really make much difference to  a standard WRX newage one then for aiming around 330bhp?

[Bing]

No my good man, ive done this operation and dont have the updated power figs but its negligible

[DR Motosport]

First time it actually failed the MOT as it wasn't warm enough, so it was taken for a hard drive to heat it up, then it scrapped through.

Probably better to speak to AndyF about the advanages of an STi 8 intercooler, but if you've got the budget to do it, I'd say yes. Standard intercoolers are supposed to be good for about 330bhp, and the STi 8 ones for about 380bhp. It's all about cooler temps and safety margins I suppose.

David

[WUZ]

David, you hit the nail on the head there M8! - Its all about Charge temp control and safety margins/Knock control.

Get rid of the cats first so you only have to map the car once ( once you get the BUG they will be the first thing that need to come off, as they are wwat will be governing how lean andy can map your car)

 

this is a mistake that i made . And im tight with my cash.

 

lol

 

Higgy.

 

P s. Oh and you dont need a cai for the level of tune you are going for, i was running 310 bhp on the standard airbox with a pannel filter.

My car was stone cold and made it through. It wasn't Greenpeace friendly but it didn't scrape through [:#] ( i.e it made it fairly comfortably ( 100 cel TSL cat)

CGS

[drb5]

 

Lol, hairy muff. As far i am aware, they do need properly heated up, to make them "friendly". []

 

 

I ran my old RA with a newage WRX intercooler, which got 320/300 on the rollers, while not even reaching full boost. Ok, there will be benefits from the STi intercooler, but i wouldn't say it's NEEDED from the way Chris drives the car and what mods he's going for. I agree with Higgy on the CAI, but Chris is wanting loads of noises when you lift off the throttle. [8-)] []
