The ebay intercoolers aren't bad for the money, my mate had one on his Pulsar GTiR which had a daughterboard fitted to the ECU allowing it to be remapped easily (by Matt @ The Racing Line), he was running 389bhp @ 1.4bar from a GT3071R turbo.

His clutch started slipping and was changed for an RPS Streetmax with heavy duty cover, it held the torque no problem and would launch without slipping but it was bloody heavy, very reasonably priced though.

Brakes are shite as standard, but plenty of options available, Wilwood do a very nicely priced upgrade.

Looks a hell of a car for 800 quid, it'll tidy up very nicely with a bit TLC.
