I plan on turboing my 97 2.2 with a Garrett T28BB turbo. But before that I want to rebuild the head because it is weak on the LN2. My question is should I get a new cylinder head off of
http://importperformanceparts.net/ or just rebild the internals of my stock one. And if I do buy a new one which one should i get off the site. Goal is about 300hp. On the site just go to cylinder heads and look. Thanks
Also I have heard about doing a piston swap from the 2200 for higher compression. Thoughts on this?

you can turbo any engine, but raising the compression ratio by swapping in 98 and following pistons will raise the CR to about 10.8 to 1 which is counterproductive for turbo applications. It would probably be a better idea to go for some forged 9 to 1 CR pistons like Wiseco, etc.

I realized that right after I posted this haha. I was thinking either 8.5:1 or 9:1. What else should be done internally. I will do pistons and rods. Than idk about the new head or just build off stock
Im about to pick up my 97 head from the shop.3 angle valve job1mm over valves 6500 rpm springs decked.030 port and polish etc. and I'm only in it like $500.
Your gonna need to do a top feed conversion, or you will never see your goal.... I also don't think think that turbo will be efficient for what you are looking to do either....

There's a top feed conversion in the classified right now. It looks like the hard work is done for you. Good price if you ask me.
can the side feed injectors not handle beyond stock conditions?

you have a better chance of ice skating in hell.
I need a new sig.
Can somone please educate me as to how much diff the flow rate of the 2200 injectors is from 2.2l? And I understand for big power or boost you must change, but what is the cut off point? If somone could let me know it would be appreceited.

myth if you get an extra injector controller you can add an injector or 2 into the charge pipe.

It's not that the 2200 injectors flow a lot better. They are just a lot more standard since they are top feed. The reason that is important is because no one to my knowledge makes larger side feed injectors that fit our car. There is nothing wrong with Side feed injectors. The Toyota supra used them, and those cars are horsepower hogs!
So, converting to top feed allows the use of larger, easier to get injectors.
