Ok, heres the situation. On my 1.4 Astra G Ive managed a 100% succesful engine transplant from a 1.8 Vectra B. Old engine was 90 BHP X14XE, New engine with some mods 135 BHP X18XE1. Full wiring loom, New ECU and Throttlebody, Running sweet. Very torquey.
My original f13 gearbox is about to S**T itself. I need to change my gearbox.
I got a free F18 gearbox from a vectra off a mate but the problem is the drives are bigger than my 1.4 drives. If I get drives off a Vectra will they fit straight into my 1.4 hubs and are they the same length as the Astra drives? The other problem with the gearbox is that on my existing f13 box there is a connection for what I assume is a speed sensor for the ECU, but on the f18 box there is no connection and the hole where it should be is plugged, is it possible to remove this plug and insert the sensor off my f13 box?
The other thing I had in mind is getting a 6 speed box and converting it to front wheel drive, does anyone know if this box will fit my Vectra engine and if its possible to still use my hydraulic clutch?
Or if anybody has any suggestions on another gearbox i should use Im all ears.
