Worth going past stage 1? *Advice appreciated*

[joemorgan2000]

Hi all,

Went stage 1 in my st180 and am up to 210 at the wheels, feels fantastic and a much better car.

I have no physical mods only a good tune, but wonder, would I get particularly significant gains out of also adding an intercooler, sports cat and intake? (not interested in doing the exhaust really as sound isn't important to me).

If so, would i also need to get another tune done on the car?

Is it really worth it? And will it stop the car being so reliable/lasting me a long time?

Many thanks in advance all.

Sounds like you're already at the limit of the stock turbo. A better intercooler won't really give you more power, but it will give you more consistent power. Your intake charge will stay cooler.
A sports cat won't help unless you're going big turbo with big numbers. Even then, the stock cat and exhaust aren't really restrictive. People change exhaust more for the sound than for any measurable gain in performance.
There are some gains to be had with a better intake.This is from a US tuner, but it's the same engine:

I was happy with stage 2 with just a IC upgrade since last summer. No problems to speak of and the gas mileage hasn't really changed.

Only reason would be to run an e30 tune

You need an intercooler and LSD. The stock intercooler can't keep up with the heat of an improved tune.
