is an aftermarket intercooler a must on stock boost?

I dunno whether to get an ecu or aftermarket intercooler first. Which would be most beneficial for this car93 silver/red touring as I have no idea what to add to this car for more reliability and fun factor.

I assume it would have an ecu on it now. I see an intake, and in the for sale info a full exhaust. Pull the ecu and look at it. I'll bet its a Pettit/PFS/M2.

Car looks great. Just drive it.

would it hurt to get the intercooler though and maybe a fuel upgrade or would I need to get another ecu upgrade?

The car sounds great. The intercooler is not necessary around stock boost levels. However, it's still a POS. The stock ic is fine under 14psi.

Steps to mod that FD.
1. Upgrade ECU...A'pexi Power FC or Pettit's unit.
2. Upgrade fuel pump
3. Upgrade ic
4. 1300cc secondary inj.

Are all these steps necessary? Nope. However, I definitely recommend upgrading the ECU. The next steps is only necessary if you want to increase power and have a reliable car if you increase hp.

keep it stock until you brake something.

I wouldn't suggest using the stock intercooler above 12 psi. With over 100k on it, it will probably break. Even with lower mileage, the stock intercooler doesn't flow that well.

Upgrade the ECU first if it has not been done already.
