1st gen B16. id like around 180whp or in that area.. will be a track/some street car... i dont care where i make the power as long as i make it

 

Try dh-racing.com. They have a b16a dyno of a stock bottom end 1st gen b16 w/ his ported head, manifold to a 70 mm tb, ctr cams and bolt ons made 189 to the wheels. Good Stuff

 

Personally if it were me I would go with a 1.8L block to begin with... It's just a lot easier start... We have a Mustang Dyno (this has been debated in the FI forum) which in general read lower than say a Dynojet (which many more people have)... A B16 in stock form normally will read somewhere around 130-140whp and 90-105wtq... A 40whp horsepower increase is hard without displacement... For instance a couple of our older CRVTEC's stock sleeved with 11.5-12.5:1 compresion, Portflow headwork, cams ranging from OE to aftermarket (CTR, JUN3's, SK2S2/3's, EF1, and Toda) fully tuned these guys make anywhere from 185-225whp... Tho these motors may read higher on a dynojet/dynopack these are what we stick too... One of our race motors a couple years ago was a 2.1L LSVTEC running 15.0:1 only made 265whp and 165wtq on our dyno... Sorry I went on sooo long but just tryin to explain why I would swap blocks... We've built B16's but normally you just want more later... If you do stick with your B16 it's going to take some high comrpession and a good selection of headwork/cams... Just my $0.02

 

Jun's b16 crate motor dynoed 235whp on a bosch in front of my face. I'm sure everyone will agree the Bosch dyno spits very humble numbers. Let the flaming begin...

 

Must of been a psycho *** B16... I'm not gonna argue, I really don't care, haha

 

Where are some places that sell crate motors? I would be very interested in just buying an engine that is already built from the start.

 

Before someone flames me, I'll expand on my experience. One: The japanese machine shops, for the most part, can bore tighter tolerances than u.s. shops. Japanese crate motors I've personally seen have given pre break in leak downs of 7-8% and as low as 3% after break in. Anyone who has built a motor knows 3% leakdown is amazing. The machinery in Japan are designed for small displacement engines. Two: for anyone thats seen a map of the JUN ecu will note the agressive timing curve. and blah blah blah ...I just lost interest. E-beer anyone?
