H2 Transmission question-what's legal?


Recommended Posts

Posted

If I were to run a B16a powered car in H2, would using a USDM Type R transmission be legal? Or must I use a B16 transmission to maintain legality?

 

The USDM Type R tranny has the EXACT same ratios (& final drive) as the hydro B16a trannies. The only difference is that most hydro B16a trannies do NOT have a factory LSD. Since final drives and LSD's are open anyway, there would be no mechanical difference or advantage in trannies. The ONLY difference would be the transmission code/stamp.

 

The Type R trannies are labeled: "S80"

 

and the (hydro) B16 trannies are coded:

"Y21"(94-97 Del Sol VTEC/JDM hydro B16's) or "S4C" (99/00 Civic SI, JDM SIR II)

 

What's the verdict?

 

thx

g) Any OEM transmission from a particular series of engine may be used with the same series of

engines. Example: Any B-series transmission may be used with any B-series engine. Only a Hseries

transmission may be used in with a H-series engine.

 

You should be fine.

I'm an idiot I must've missed that part under THE H2 RULES. Sorry to waste people's time

jmeris.. our h2 car is a b16a with jdm 98spec itr tranny (4.7 fd with itr final drive).

 

it also has 98spec itr cams, intake manifold & throttle body. it dynoes 154whp @ Blacktrax.

 

I turned a 2:03.x and a few 2.04.x's during sundays last hpde 4 session. It's a great setup, and a blast to drive!

 

come join h2 with my dad!
