Your going to hear the same answers and arguments over and over from both the N/A, and forced induction people for this question. I would find something that suits YOUR preferences. Do some research, search the threads on here, you'll eventually come to that decision by what you learn.

Either way, build something that will be functional and reliable. That's something everyone will appreciate.

 

budget turbo kit ftmfw

 

I think i have finally come to a conclusion i got some friends in good places so i can get a turbo set up for about 1500 and so right now im stuck on whether im going to get either a gsr/b16 head or get a whole new gsr engine & tranny

 

Don't cheap out on the setup and your good to go. Just like the NA vs turbo you will hear a lot of different opinions on which is better. Personally I would go with the GSR head.

 

Actually if he was going boost I would go with the b16 head. The combustion chambers are better for boost due to their circular shape over the more square shape of the GSR heads combustion chambers.

Correct me if I am wrong...

 

you're splitting hairs with the b16 vs p72 head. get the compression to a respectible number, reinforce the bottom end. ARP rod bolts, main studs and a block guard probably wouldn't be a bad idea if you're going to use a stock non-sleeved block. personally, if i ever did a turbo motor i would use the dart block. then again my prefrence is with motors that will hold up to years of road racing.

two things matter with a combustion chamber. one is the shape, how good that is can be detected with a gadget that measures swirl and air speed. the second is the size of the darn thing and if it will work for the piston that you want to use. i'm really sold on these mahle power pack pistons when it comes to the honda motors. they are light, strong and you can set up the piston to wall a variety of ways depending on what you're using the motor for. .0025-.003 for a mild normal driver. .0035-.004 for a NA build that gets the skit drivin out of it or a mild turbo build. .004-.005 for high boost and mahle mentions that .006 is even alright if you absolutely get nuts with the cylinder pressure. nitraded steel top rings, gosh, it doesn't get much better. i have no clue why anyone would run any of the stock honda pistons with the prices these guys sell for.

lastly, one more note on chamber shape. generally open chambers aren't as desirable as one that promotes a high rpm swirl. in v-8 land thay have gotten leaps and bounds better in the past 20 years. to the best of my knowledge all of the higher end honda heads use a high swirl well designed chamber. that's how people get away with pump gas and 11:5-1 compression. in v-8 world that can only be done with the very best of cylinder heads, a proper tune, and a cam big enough to bleed down some of the cylinder pressure.

I think i finally decided im gonna get a gsr engine and tranny build the turbo on that, that way i still have a street able car until i am done w/ the gsr cause i can boost the engine pretty well for about 1,200 and get and engine for 3-3500

 

Boost that bish
