The non-vtec builds have seemed to be popular lately so I decided to start my own thread.
The engine has been in the car and running for a few months now, I just added a set of cams last night.
Untouched JDM B20B bottom end

P75 Head Milled .035", cleaned and fresh VJ

Assembled Before Install

Installed in EK Hatch with S4C trans

Engine Spec's
JDM B20B
Head Milled .035"
Fresh VJ
B18B intake Manifold
B16a2 Throttle Body
AEM ITR CAI
Edelbrock Pro Flo header
WS2 Exhaust
BDL Cam Gears
RC 310cc Injectors
Vtec Oil Pump
Vtec Water Pump
GSR Timing Belt
Engine ran quite well but fell on its face pretty hard on top end, once tuned it got ~ 30mpg average.
I had been scouting H-T for a set of mild cams to install, something that would not require a valve train upgrade. (I have a whole other project and had not wanted to spend a lot on this one) I came across a set of mismatched Crane cams on Ebay that I won IN CAM #101-0012IB and EX CAM #101-0010EB. Before bidding I did some research and found that the 101-0010EB EX cam is smaller than the 101-0012EB by about 4 deg with the same lift so I went ahead and picked them up.
Install

Engine is running a bit off after the cam install, rich on idle and lean elsewhere, as expected. I will be street tuning it this week an trying to make it to the dyno friday.

.I thought the valve reliefs in stock b20 pistons werent deep enough to put in bigger cams? Maybe those arent that big? or maybe thats just with a vtec head, i duno..</TD></TR></TABLE>
The cams are VERY small. But you are thinking of bigger cams in a Vtec head non-vtec block, the valves are larger on the vtec heads and dont fit the valve relief's of the non-vtec pistons.

So this isnt project "cookie cutter" then?
What kind of VJ? Just bump the 45, or a nice 3 angle deal?</TD></TR></TABLE>
Project Cookie cutter is another motor all together. Its noting amazing just all of the H-T hype parts. RLZ.RMF,Pro2,Carrillo,ATI.....
VJ was done by a local shop on a sunnen I forget the exact angles, something close to an OEM ITR 3 angle with a 1mm seat.

reminds me of my build for my eh3 that i sold... a budget build with rocket motorsports internals and a p8r head.
you should see some pretty decent numbers with yours, can't wait to see the dyno
