Hi, I just recently bought a B16A2 short block from my buddy (He had an extra) and i am planning on fully building it (obviously I'll need a head). But my problem right now is not knowing exactly what parts to buy, or how much power i can expect from it. I haven't exactly set a budget just yet because I'm not sure what to expect. And yes i want to go all out, with the rods, pistons, cams... But im not sure on what to do to the block and what what parts i need to get to match with the work i get done to the block/head.

I was thinking of shooting for about 200whp, but I've talked to the guy i bought the block from who's a bit more experienced than me and he says that 200whp is a bit steep. So i was just Wondering whats a good starting point to look at?

And no i haven't picked it up yet i still need to do that but, the short block is in pretty good shape, but it does need a few sensors and such, but that part i can figure out later on in the build.

And sorry if i posted this on the wrong section, keep in mind this is my first post on Honda-Tech.

P.S. This is mostly a build for a street car, i will probably track it but it will be my daily drive during summer.

 

B16's are not easy to get to the 200whp mark. And even with that power you still have no torque. To be honest if I were going to build a B16 I wanted to get power out of I would make it built for a 100 shot of nitrous strictly for racing only.
Rough outline would look like this...again this is just my opinion if you want power out of a B16 for racing, but a nice DD that will be reliable and get good MPG.

B16 block crank and rods w/ p30 pistons
GSR head w/ITR or CTR cams, TB, and header
B16 tranny
100 shot of nitrous and you can make 225whp on the juice with a proper tune.

All the answers are at your finger tips. Enjoy

 

You definitely don't need rods and pistons to make 200whp.

 

Thank you for your opinion, i definitely don want to go the nitrous direction (not a fan to be honest) but right now what I'm trying to figure out is how much should i bore the b16, they say 81.50mm - 82mm max with stock sleeves, and not sure on the compression ratio. I am mostly going to get my parts from BC (Brian Crower). GSR head should bolt right up, right? but how is that going to affect the compression ratio?

 

A 200whp B16 is going to be pretty highly strung. I would recommend more displacement. A 1.8 will be better, and a 2 liter will only need a mild build to get those numbers.

 

Compression will depend on a lot of things: fuel you will be using. Cam specs. Etc.

But a good all motor street ratio is around 11-11.5 IMO

The gsr head will bump the cr a little also
