New Setup: All Motor - 97 Civic - G23 VTEC
Ok, well all the prelude guys are gonna hate me, but I am getting a 97 civic ex coupe and going all motor... Time to get rid of the turbo kit and use a lighter chassis... Here is the plans for the new setup:
-F23a1 Block
-F23a1 Crank - 97mm Stroke (Rod journals widened to accept .935 B-Series rods)...
-Custom 147mm (5.788 in) B-series rods...(Possibly notched for GSR rod bearings)
-Weisco Pistons (.940 compression height) - 86 or 87mm - 11:1+ c/r... https://honda-tech.com/zerothread?id=1323338...
-H22a1 Head(Crower Stage 3 cams or Custom, RM valvesprings/retainers)...
-RMF Exhaust Manifold
-Removed: Balance Shafts, PS, AC, CC, IAB, EGR...
-Lightweight: Crank Pulley, Alt. Pulley, Flywheel...
-CM Stage 3 Clutch, Quaiffe LSD...
-KTeller 2.5" Mandrel Bent Exhaust
2253.6cc with 86mm bore... 2306.5cc with 87mm bore
...
Not sure on the exact power but I'm sure I'll make well over 200whp and more torque than jesus... Looking for 12's all day long... With the shortened compression height and longer rods, it brings the rod/stroke ratio from 1.45 to 1.52 which isn't anything spectacular but should be enough(in combination with the wider rod journals) to prevent me from spinning rod bearings at moderately high RPMs... My expected rev limit is to obviously be around 7200 to be safe, and I am definitely considering custom cams to accentuate the low-end/midrange and to keep the powerband from going to high... As always, any questions/comments/ideas and suggestions are welcome...
