Right after doing my first rolling road today and having a near standard 20VT (Gtec1 and K&N cone filter), I got 226bhp, which is not bad on a standard car that’s done 117000 miles. As I’m a moding virgin I need your help? Could someone help me with a list of components I’ll need and an idea of what cost is involved?

I’m not planning on building something that goes over 400bhp but more in the 300’s would be nice! ?

Thanks for your help, Mr C

Yes, get a standard Airbox and GTECH 2 for starters

Did not take you long Chris

Well you know how it is, I can't give up with the coupe just yet!

And glad to hear it too

Glad to hear you're keeping the coupé Chris.

As for mods - cooling, turbo, exhaust & fuelling.

£459 - ProAlloy FMIC (possibly cheaper on a GB)
£700 - GT28RS (ATP Turbo)
£400 - Blueflame 5 stud exhaust
£150 - Walbro fuel pump & direct battery feed for pump.

You'll also probably have to change brakes and clutch.

Oh and no boostie boostie until you get that chip changed.

And £200-£300 for a remap, try and do it when youve finished a "stage" of mods, cheaper than going back after every new part is fitted.

I would add:

Unichip - £250
C&B Cams - £800 (fitted)

P.S Strutbrace - £100

God, just totted that up, comes to over £7000 without servicing, bodywork, previous alloys and tyres and previous brake parts.

Get the boxster 3.2S

Cheers Guys! Will start looking in this now! Just about to put my standard chip back in, do I need to disconnect the battery? I can't remember! Ta, Mr C

Stuff that, £16k will buy you an SLK AMG 32 with 350 bhp

What on earth am I doing in the tuning section?

Where the hell do you get C&B cams bought and fitted for £800?

Here we go then! Leave the car as it is until you have got enough money to go for the spec that you want, then go the whole hog at once.

Problem is that I have the money but I need to know how much the whole hog is and then decide if it's worth doing it to my current coupe?

What is your target? You also need to ask yourself if you really want to go there with a coupe - once you've done it you wont make the money back.

This is my dilemma! Something over 300bhp?

Mine were bought and fitted for £600 actually

When i bought mine new ones were £650.

LOL - how reliable do you want the car to be, and how do you want the powerband to be?

As reliable as poss and as i'm a moding virgin can you explain what a powerband is?

How quickly the turbo comes on boost and the car becomes usable. Basically, there are two ways to increase power:

1) Whack a bigger turbo on it

2) Conventional engine tuning (cams/headwork/exhaust/etc.)

The cheaper option is 1). But, the car will only really get going at higher rpms than option 2) So do you want something that isn't as hairy at the redline, but is very drivable, or something which takes a while to get going, but turns mental when it does.

if you're going for 2, then there's also a lot less stress on the engine....

You could always combine both options!

What you really need to ask yourself is do you just want a faster car, or a faster coupe? If you want 350 bhp then there are better base cars to use with more traction and you wont have to spend as much money to extract the power.

None of them look as good though
