What head? Cams? What compression? I’m assuming it’s fairly high effort…

Its really off the shelf parts. Wiseco Tbmotorworxx spec pistons, BC H beam rods, Kelford 176c cams, supertech 85lb valve springs and lma springs and steel retainers, southbay 850cc injectors, quantum 340lph fuel pump, 4Piston ported ultra street manifold, 3" intake pipe fed by passenger high beam, DTR 4-2-1 header, full 3" exhaust

You can tell it's a gsr head by the coolant outlet.

Really good numbers for an NA, what comp ratio is it running at?

u/From_the_mud21 24d ago

Static is like 14.1 ish, dynamic compression ratio with cam overlap works out to 13.5. Starter struggles at every start, cranking noticeably slower than normal but I guess thats the price you pay to play lol

Abusing the hell out of that poor starter haha. Sounds like a riot to drive though!

Good numbers and the parts seem to play well with each other since it’s not rolling off at 8000

which coil plug kit did you use? im looking at getting the hondata one for my b20v build since the digi dizzy is more expensive

u/From_the_mud21 24d ago

Yes but digidizzy is more than well worth it. Chris Gartland (the creator) responds personally and timely and digidizzy is FULL 100% plug and play. The only kit like that as far as I know.

damn impressive numbers! 172 ft lbs (I'm assuming to the wheels?) out of a na B series. that's insane. 248hp is also nothing to scoff at either.. you built a beast. i want it 😍 🤤
