is there any difference in horsepower/torque between the JDM B16 and the Si's B16A2???

 

no difference in horsepower. probably no difference in torque. they are the same compression and maybe a slightly different cam, i'm not really sure on the cam.

jdm b16a from an sir2 (the eg6 motor) does have higher compression (10.4 compared to 10.2) and is rated at 170 horse but i'm not sure of the torque. before i was refering to the sir1/xsi motor (obd0) which is rated at 160

 

i think the 1rst gen. makes 160hp and the 2nd 170hp when in vtec, but maybe im thinking of the b16A3 makes 170

 

b16a3 is the del sol vtec motor. it makes 160. all usdm b16's make 160. the sir2 or "second gen" b16 (basically all jdm obd1 b16's) are rated at 170 and all pre-obd jdm b16's are 160

and i think the cams are a lil more aggressive in the b16a2, vtec hits harder and is louder...

Read, it's good for you.

 

and yes, that is the b16a2

 

kool...i knew there wasnt a difference in HP and TRQ.....just making sure.....THe B17A has also 160 HP but it has a little more torque.....right?

 

i know it has the same horsepower, it might have like 112 ft lbs of torque, but i'm not sure on that

 

this website seems to be right but not sure

there are 2 types of b16's not including the ctr (b16b)

There is the first gen kdm b16a which has 160hp and 111 tq just like all the usda b16's (b16a, b16a2, a3)

and theres the jdm second gen b16a which reads b16a just like the first gen
this one has 170hp, higher compression better im

the only differance between the usdm b16's and the first gen jdm b16 is that the jdm first gen b16 has really small LMA which suk.

all jdm bseris vtec motors also has a oil cooler

160 hp and 117lbs tq with measly low compression wish they came stock with bumped up compression oh well &lt;shrugs&gt;

 

when u change from ob0 to ob1 u gain about 10 hp due to the fact that the ecu is dumping more fuel to the engine

 

How would u raise the compression on the B17???

 

Changing the pistons would be the sure way to get the compression you want. many people go with p30 pistons ...good way to bump the compression yet its still at a safe number...
