I am building a b16, and looking for approx 450whp, all i ever see on the place is boosted b18's, is it because the low end power and torque? just curious why the b16 is over looked?

more displacement/tq which means more power on same/less boost

as previously stated; more displacement.

but, in my opinion, b16 makes a fun street car.. they are rev happy and do good on gas for daily driving. 450whp is pretty easy to make with a good setup pushing around 20 psi.

i'll tell you right now though, anything past 14psi isn't going to hook up on the street without some really nice drag radials on a middle weight civic chassis. speaking from experience, I have a '96 ex coupe, 2400lbs, b16 9:1 c/r pistons and a t3/t04e pushing 10 psi on some kumho ecstas.. I can only hook up with 3/4 throttle =[

No replacement for displacement!

spoolin turbo s

more rpms is a pretty good replacement if the smaller motor can turn 1500-2000 more rpms displacement isn't gonna matter

tony413

rpm's = more stress on the bottom end

so the saying is still true theres no replacement for displacement. but thats why we have FI

I love my boosted b16, and with the right head work you can make as much tq as a 1.8.....The only bad is ive gone threw 2 b16 blocks cracking sleeves...seems like they break easier...gl with you build

not entirely, the piston speed of a b18 at 8000 rpm is just about the same piston speed of a b16 at 9000 rpms, let's not forget stroke has an effect here... efficiency, rpm, and boost are all replacements for displacements...

im running a ls/vtec 81.5 bore right now if i would build another car i would build a b16, less torque and it will a linier graph like a all motor car, so you dont have so many traction issues just my 2 cents

tokesGTR

Yes, it is going to matter. And no, a B16A motor cannot rev 2000 RPM's higher than a 1.8. You'll be limited by camshaft and cylinder head technology before stroke prevents you from revving. Lots of B18's that rev to 10+ thousand

a boosted B16A EG from Inline Racing become the first SFWD from Houston to get a 9 second pass at the Ennis IFO this past weekend. we love our stroker B16A's

tokesGTR

Stroker B16's are ridiculous.

Less deck height means the wrist pin is higher up in the piston. Less piston strength, less piston stability, more ring wear and wear on the bores.

A B16 with a GSR/LS crank is chock full of disadvantages compared to an actual B18 motor, with nothing to gain other than maybe a miniscule weight advantage due to the shorter block.

How are they redicilous if they are running 9s?. seems like its doing just fine to me

ExVtec

My b16a2 was making 450whp+ for over 4 yrs on just a rod/piston setup.

I loved that car.

irishflame27

yeah, it will be a street car and will see some track time for sure, hoping for low 11 sec passes, im hoping the lack of torque will help keep the wheel hop and spinning to a minimum, i will be running a gsr trans and 24.5" slicks for track use.

The majority of the reason you see so many B18's are because LS longblocks are cheap. People are either starting builds with an LS, or building LS/vtecs right off the bat. When you look at the cost of an OBD1 B16 longblock, you can build an LS/vtec with acl rod bearings and arp rod bolts, and spin that motor like the B16 while making more torque. In addition you can start with the LS and build further later. That's the reason there are so many B18's.

also the b18s usually have a lower compression from factory than a b16 there for stock for stock can run more boost

i'm running b16 over-bored short block forged internals.. stock gsr head... t3/t04e 50trim 326whp / 255tq@ 1bar

irishflame27

honestly if you were to race two ek hatchs one with a GSR and one with a b16 both making 450whp, would there be any significant differences, take driver error and ability out of the equasion, what would a race like that yield?

stockb18c

ya i have a b16a on sc44 on 10-11psi and i loved it then ringlands blew lol but now im rebuildin with 9:1...b16 have less stress on there motor then b18..less stroke less friction which mean more realible
