Headgasket changing isn't that expensive, it might cost $200-$300 to get a copper head gasket, and maybe $80 to get the head o-ringed, provided you can take the head off yourself (not that hard with the engine in the car, even easier with the engine dropped out) then you are looking at about $400 and approx. 4 hours of your own labour (depending how quick you are at getting head off).

The reason I'm changing the head gasket is for future proofing, I'm hoping that someone on these forums will buy my car when it's done and I expect that the knowledge that it's ready for more boost (internally) will be a good sales pitch Very Happy

That and I might be trying to get my hand on some 550cc injectors thus upping the boost will again be possible Razz

Aftermarket ECUs for Gen 1's (ST165 motor) is limited to swapping over for a replacement aftermarket programmable ECU, or using a SAFC or FCD to get limited improvement. So you can either spend a little bit (SAFC/SAFC-2), or you can spend bucketloads (on Microtech or Motec etc). I think Wolf3D might also be looking into this one (or is it limited to Gen 2 motors?).

Front mount intercooler set ups? Possibly lots and lots...ask StuC seeing as he's doing this one on his ST185 - you could get an idea from there, although it'd probably be even more annoying and expensive in an ST165 as there isn't room for a bee's nads in the engine bay. Then you have to consider how on earth you are going to get good airflow to the intercooler!

Rebuilding with stronger internals is going to cost an arm and a leg, but I've heard from many reliable sources that the pistons aren't up to the task when the boost is upped (this is all in relation to the Gen 1 motor out of the ST165, i hear that ST185 pistons aren't alot better). One other thing to consider is you don't know how good the condition of a second hand motor is, and it can go bang quickly if you give it a hard go (that means driving crazy like me, or making mods to the engine to get more power out of it) so sometimes pulling the engine apart and making sure everything is in perfect nick is a good idea before you start going bonkers.

I will admit that I can (and do) drive quite hard on occasion, and that's why the engine needs to be really up to scratch (read : tough). You can get away with 15psi of boost on a relatively stock engine (improved fueling and intercooling system). But it won't take prolonged punishment, maybe a bit of a squirt of the throttle every now and then, but I would definitely *baby* the engine, which makes having all those mods kinda pointless Very Happy
