im about to turbocharge my 1999 SVT contour and ive been searching for ever does any1 know were i can get low compression pistons for my car...its the stock 2.5L thanks
 
And if you're gonna go to the effort of doing a turbo and looking at new pistons, you might also consider a 3L engine.
 
You really should consider a 3.0L with 3.0L heads to get rid of the 2.5L oiling problems. I'd hate to see you put all the money into a 2.5L and then spin a bearing.

I don't think that the 2.5L heads are that bad, I ran them for several years without issue. I agree it would be better to have more oil drainback though. I just don't want people to think that 2.5L heads don't work.
 
im only 15 tho..my mom would flip if she knew i was getting a new motor haha. she wouldnt be mad if i just built up this one plus ive been reading alot and havent seen very many 2.5L's turboed

Haha, and shes not going to flip when you pull the engine out of the car to upgrade pistons? :laugh:

Id say theres about half and half floating around. Some people started out with a 2.5L and unfortunately either grenaded a piston or spun a bearing and then upgraded to a 3.0L.

Unfortunately, ADC no longer makes any turbo kits anymore for this platform, but they do pop up in the classifieds from time to time. The kits were $5000-6000 new depending on which kit you got, so they generally go for about $3000-3500 used. You might be able to build your own kit for cheaper, but its a very labor intensive job and definetely requires some knowledge as to how a turbo system works. Vortech used to made a kit too, but unfortunately, unless you get a revised kit, they carry a 100% failure rate.

I hope your mom lets you do this to a car, but I must warn you, upgrading to a turbo kit is expensive. A lot of other components need to upgraded as well. Myself including others have well over $10,000 into our turbo projects. It's cool to dream though. I know when I wanted to swap a 3.0L and turbo my car, I literally budgeted my money and took me 3 years before it happened. ;)
 
o yah ive been reading up on it i think im just gonna build up my motor and LSD and transaxle and stuff befor i turbo it i might even change out the block to a 3L
