httrdd Posted December 14, 2009 Share Posted December 14, 2009 This is just another reason to build up the internals. What do you guys recomend to do as far as aftermarket crank and pistons since I will have the engine tore apart. I would like to stay n/a unless I change my mind. I am building this up for performance anyways, so just another excuse to mod! Link to comment Share on other sites More sharing options...
WESTcoast Posted December 15, 2009 Share Posted December 15, 2009 nice nice you get the luxury to do the world of internals such as forged pistons, camshafts. If you can try to get some of your internal stuff port and polished so you can have a larger displacement goodbye 2.5l hello 2.7 or 2.8liter hahaha. Sorry I don't know that much about internals stuff but I know you can have a track ready engine with the proper equipment Link to comment Share on other sites More sharing options...
fatboy1214 Posted December 15, 2009 Share Posted December 15, 2009 i agree get your heads port and polished along with intake and exhaust valves get bigger cam bore it out, pistons to match, bigger crank if you can all adds up to bad ass Link to comment Share on other sites More sharing options...
httrdd Posted December 15, 2009 Author Share Posted December 15, 2009 How much of a power increase can I expect port and polishing, cams, and forged pistons? Anyone can just drop in a engine and go if you have the money all up front. I figure I will port and polish heads (maybe swap in different heads), bore out cylinders, then figure out what size pistons I want. Change out seals and gaskets while I am at it. I like a challenge!

fatboy1214 Posted December 16, 2009 Share Posted December 16, 2009 ohhh you will definitely feel a difference in power im not sure on the power increase depends on how much metal you take off everything also depending on what motor and everything you drop in it very well could be cheaper to do that and have more power with supporting mods of course Link to comment Share on other sites More sharing options...
pierce88 Posted December 16, 2009 Share Posted December 16, 2009 For the kind of cash your talking you should just swap in the drive train from a wrecked wrx/sti... -Pierce Link to comment Share on other sites More sharing options...
WESTcoast Posted December 16, 2009 Share Posted December 16, 2009 your probably looking at a nice 15-20hp gain with a nice set of internal work done but this is a guesstimate. I have a friend who had his stock wrx internal ported and polished and on ecu tune, he made a nice 30+hp with that, but thats because he is a turbo and had a open source tune but thats another story lol Well for a good set of internal work it can be a nice 1000-1500 for parts an labor, on an engine swap your looking at 3-5 grand on a wrx swap and more for the sti swap Link to comment Share on other sites More sharing options...
httrdd Posted December 16, 2009 Author Share Posted December 16, 2009 Might of found a set of DOHC heads that have been ported and polished, new internal and gaskets. I cannot wait ! Link to comment Share on other sites More sharing options...
DN1911 Posted December 17, 2009 Share Posted December 17, 2009 on an N/A car there really isn't a reason to replace the crank unless you want to go with a bigger crank. also i don't feel forged pistons will be worth the extra money unless you are doing High compression or forced fed or nitrous. good old hyperutectic (spelling?)will be fine. now P&P head with bigger valves and good cams will go a long way with a good bump in compression. if i could i would something around 10-11:1 compression 2.3L with a P&P heads with titanium valvetrain to rev to the moon with some nice Delta 2000 cams and good tuning! it would be a great N/A package Link to comment Share on other sites More sharing options...

I know if you have a schoc long block and dochc heads you'll have higher compression for what i was told, I was thinking of doing that, but sounds too risky on not solid info Link to comment Share on other sites More sharing options...
