some time in the near(ish) future im planning on ditching the 173 and 3 speed for a 253 and 4 speed. does this take much work to the engine bay (ie altering engine mounts etc), and if i do this myself can i get an engineers certificate? how much would an engineers certificate cost?

You dont mention what vehicle you are putting the V8 in. You can do all the mod work yourself but i would suggest that you let an engineer see all your welding before you paint/ coat them. As for cost work on $100 per hour

assuming HX all youll need to do is prove emission compliance with on the new engine (which means hx or later donk) and inform your RTA about the engine number and go ahead and swap.

Upgrading to a driveline that was a factory option, for that particular vehicle, should not require an engineers assessment. No cutting or welding required & a braking system that was designed for the larger motor. As greenhj mentions, you would need to consider the emissions compliance. Use all correct, factory components, i.e. bolts, mounts etc. Contact you state rego branch for confirmation. Remember, it is with them that you need to have the vehicle legally registered, not with any of us nuts on the forum. Enjoy. Personally, I know you didnt ask, but I would rather slip a nice little injected 304 in rather than a 253. Cheap, efficient & reliable power.

I know a number of guys that have bought a complete VN wreck to scavenge the full driveline for V8 conversions. Generally these are for early Holdens, but the principle is the same. Cost of a crashed VN with reasonable running gear, easily under $1000. Make use of the TH700 4 speed auto or go manual. Keep in mind, this is all the easy & cheap bit of either 253 or 304 conversion. Extras include, but are not limited to: Full exhaust system. Radiator Engine mounts for V8 Diff upgrade, commodore from wreck is an option. Set up of wiring to suit injection management, taken from wreck. Fuel return line for injection system. Personal choice will make your decision. If you like more original, go for it. Just thought Id get you thinking. Enjoy the work. Utility8 |

Yeah if the 253 was a factory option for the vehicle, then you just put all of the 253 components as fitted to the original vehicles, including any brakes or steering etc. http://www.ehlimo.com.au/ |
