Hello all. I don't have a tachometer on the cluster. My other stick shift car is a 88 crx HF, the hf stands for high efficiency so the gears are very tall and shift poits are specific for that.
I on the Vanagon on I have a subaru 2.2 mated to a 091 DU transmission.
1st gear 34:9 = 3.78
2nd gear 33:16 =2.06
3rd gear 63:50 =1.26
4th gear 52:61 =0.85
Final drive 34:7 =4.86
So since I don'e have a tach I should shift to second at ___ mph to third at ___mph, to fourth at ___mph.
Thanks all. |

Run the piss out of it and don't worry about it. Unless you are just very aggressive and/or don't pay your driving much mind you aren't going to hurt anything. |

No really, I'm working out the bugs in the Subaru conversion and other that the short first test drive around an 3 acre lot, I've never driven a Stick shift vanagon. Is first gear a granny gear? how soon should I shift to second? |

Something like this should work
1st-2nd------10-20mph
2nd-3rd------20-45mph
3rd-4th------40-70mph |

I have 28.9" diameter tires. For me, a fairly aggressive acceleration curve means shift points at 4000 RPM, which puts relative speeds at:
1st-2nd 18 mph
2nd-3rd 33 mph
3rd-4th 54 mph |

The EJ2.2 Subaru redlines at something like 6500 and is rev limited to something like 7000, might as well use it. |
