Just got my wife's 93 Civic HB SI finished.
LS/Vtec, 8.8:1 CP pistons, t3/t4b 54trim(small turbo)-Beeyond turbo kit, Stock everything else internally, ClutchNet stage 2, Crome EFI, 750cc injectors, Walbro 255lph, B&M FPR, Stock IGN system, and some cool tuning secrets...
13-14psi she turned in 12.2's@114.5mph with a 1.74 60ft.... Not bad for a FULL BODIED SI model...
I'll post some pixs later.... oh and this SI gets 27-28mpg on the HWY and about 24-25 mpg street trim..............
11sec coming soon!!! 16-17psi should do it!!!
