Engine conversion

**jc109** · 26th June 2010, 03:21 PM

Hi All,

I know things like this have been covered before, but I wanted to gauge everyone's opinion on engine swaps.

I have a 2.25 petrol in my 109". It's been giving me nothing but trouble lately and I need to do some serious work to it. I've contemplated pulling it out for an overhaul and a new head, and a once-over of the gearbox while I'm at it (I think I sucked some muddy water in on the Powelines trip I did recently). This might be an easier task than a conversion, but I still end up with a pretty basic and sluggish engine.

I've thought about a Tdi and the expense and complexity puts me off.

The Holden 186 conversion seems tried and tested, but I'm curious about the ramifications for my driveline once it's in.

A mate recently suggested a Ford 250 crossflow - whatever that is exactly. He has access to parts and know-how, but again I have doubts about the flow-on effects.

Basically, I'm now keen to build this into a toy that's reliable, powerful, and that I can work on and source parts for readily. I'm happy to consider upgrading things like transfer case and diffs (locker rear and possibly front are inevitable) so the extra strain from a better engine may be countered anyway.

Brakes are another thing I'll need to consider. One step at a time though.

What are your thoughts?

Holden engine swaps are very common & parts are very readily avalibal i have the blue 202 & so far haven't broke anything.. The ford engine conversion was done a fair bit aswell & the parts are readily availible..
I did read somewhere that castle main rod shop did a v6 holden conversion which if i can find out more about i will be doing this later on ..
It all comes down to how you drive it as to how long it will take to brake something in the driveline...

Hope that was of any help . . .

What is your budget?

Do not do what most do and then have engine trouble. Do not just bung in a well used engine "as is". This is asking for trouble. Open it up and rebuild it properly, making suitable modifications for the different application.

No budget in mind. Without going stupid I'm prepared to spend whatever I need to in order to ensure it's done properly.

Whatever goes in will be 100% otherwise I see it as a waste of time.

Just an idea, why not go for a more modern 4 cylinder? The best light commercial 4 pot I know is the Toyota 22R (2.4 litre) engine out of the Hilux. Chain drive OHC and (almost) bullet proof.

I've been asking, in this thread, where one would be able to get an adopter kit to fit a cross flow but with no reply as yet. Does Banjo have any knowledge of a kit or parts needed for the conversion?

Thanks

PS, I take by V6 Holden you mean the Buick V6 used in the Australian built Opels?

you mean the Buick V6 which is the same engine family as the GM designed engine used in Rovers?

Rover has always admitted the V8 was not one of their own engines (which like the unit that powered the Aussie Opel was no longer wanted in the US) and at least used it in thier own car and not a forgien designed car like Holden/Opel.

Anyway my Rover is a 2.25 petrol so the GM designed V8 would a great improvement to my on road performance.

Bottom line is I just want to keep up with traffic and my first choice of power plant is the Australian designed, developed and manufactured inline Falcon six. Yes I know the Falcon six started out as a US engine just line the Holden red/blue/black inline six was a rebadge Chev however from the cross flow on it was an Aussie icon.
