DIY Engine Rebuild

Recommended Posts

My oil pump has gone pop and so while I have my engine out, I am thinking about the possibility of doing a rebuild. This would be a first for me and so I thought I would ask for some input from you nice people.

I have around £2000 to spend and was thinking of replacing the bolts, rings, bearings, valve stuff (springs, shims and oil seals) and getting everything else cleaned up. I intend to stick with the stock twins for now, but may upgrade to a SMALL single in the future.

What parts would you recommend (keeping in mind my budget) and what (if any) are the major headaches associated with DIY’ing this kind of thing?

With respect a six cylinder twin turbo double OHC engine is NOT something to use as a Guinea pig for your first engine build. I would suggest you remove the engine and take it to a pro, and refit it yourself, you can get some hands on and save a bit of money, without getting carried away. By the time you have collected all the gear for a proper rebuild you won't save anything anyway.

The first question...

 

1. Are you confident doing an engine build yourself.

2. Do you have a clean build area.

3. Do you have a torque spanner...

 

 

1. Fairly. I was confident enough to rip the engine out to do the oil pump. Different ball park I know, but it's still just like Lego when all said and done. :)

 

2. Yep.

 

3. I sure do.

I understand your concern. So, how much would you charge for a job like this using OEM parts and what (out of interest) is the gear that I would need to do it myself?

All credit to you for wanting to give it a go.

 

I've stuck to A-series rebuilds till I'm confident I know the engine inside out before I even think of doing something as complex as a 2JZ.

 

A-series engines are cheap to find and rebuild.. and it is good practice..
