ok i will appreciate if anybody can help me with this dilema!!!.. im a new building engine so i bought a b16 block sleeve and bored to 83.25mm 2.0L... the block is brand new never used it .the block came from a machine shop straight to my house and i bought a jg head port and polish with 3 angle job with the valve train except for the cams i decided to install crower stage 2 ...... with an port and polish itr manifold bored to 70mm throttle body....the piston are 82.75mm size high compression with b16 rods and micro polish crank the only thing that i miss is the head gasket ......becouse i dont know what should be the perfect one .....does somebody have any idea how many hp i can make with this set up???or if i need to run some injector, pump or an AEM system for the fuel system.....

 

well certainly you need the supporting mods to go with the build. i would beef up the fuel pump to a walbro 255, fuel rail and injectors. i think that would be it. then have your car tuned to reach its best potential.

what rings are you using for the 82.75mm pistons.
what brand are the pistons?

 

Have some prelude piston that I can used but I want to do it the right thing so need a recommendation and second if my fuel system get upgrade it should need an aem individual fuel system.... For it ..... What about hp what do u think about the set up???

 

83.25 bore with 82.75 piston?!? Typo?

What kind of fuel will you be running?

What compression ratio are you shooting for with the motor?

 

exactly what i thought.
hence why i said what rings is he going with lol.


best bet is to get some High comp. wiseco pisons. and their rings

as for the fuel system you dont necessarily need an AEM ems.
use your stock ecu.
get a walbro 255, fuel rail and injectors...
and GET A TUNE!

 

There is too much craziness going on in this thread...

For starters let me just say I am more of a Domestic guy and an American... so I usually convert everything to Inches then back to Metric...

You say your bore is 83.25mm which = 3.277559" and your pistons are 82.75mm which = 3.257874" - do you not realize this is a 0.019685" difference? That's a full size over-bore piston off let alone your piston to wall clearance... So you need to figure something out.

On to the next subject... You do not have a 2.0L engine from just boring it over...

We know that Pi X Radius^2 X Stroke X # of Pistons = Cubic Inch ... so lets begin.

Bore - 83.25mm = 3.277559
Stroke - 77.4mm = 3.047244
# of Pistons = 4

Pi X 1.6387795^2 X 3.047244 X 4 = 102.839 Cubic Inches (ci)

102.839ci = 1685cc = 1.685L - So if you round up you could "call it" a 1.7L

You don't have the bore or the stroke to get you to a 2.0L and given the physical limits - without changing the stroke you would never get to a 2.0L...

Also, you never said what compression or gave any real information or specficiations on the parts. Essentially, you are just throwing a bunch of crap together and hoping it works. Good luck.

 

so if u said i have a 1.7l...what kind of pistons should i use i do have stocks b16 rod with a micro polish crank....?????..... or whats the best way to built this block???thank for the help everybody

 

With all due respect, it sounds to me that assembling the motor is way beyond your skill set. Take it to a machine shop with a good reputation and allow them to take measurements of everything and recommend to you what parts are needed. Get those parts and allow them to clean, balance, and assemble your engine.
