Series, Holden & Extractors?

[baldilocks]

I bought a 72 S3 109 with a standard red 186 and LPG when I cam e over to NZ from the UK, used it as mobile demo for finishing someone elses abandoned 202 in an 88 conversion which went to eldest daughter.
The 88 drives like a dream accelerates and good for over 140kmh.
The 109 now struggles to make 80 on the flat, even with overdrive so is clearly in need of a rebuild. Electronic dissy is first on list followed by a Weber carb then better cam and either 12 port head or reworked 9 port. Now looking at extractors to complete the ensemble I wonder how well they fit a Series? Looking at the pictures I can see online I suspect most will smack into the cross members under the gearbox, rather than go under them? Somewhere about where the 6 into 2 go together.
Am I being overly pessimistic, is there a specific type that works?

There are a lot of series landies about with holden motors and extractors fitted!
Cheers, Mick.

How well does the Holden go in the 109 now after all the work thats been done, I'm very close to swapping my 2.25 for a 186 but I'm still not sure what to do, I'm leaning towards the 186 for the extra grunt.

I had an LPG powered 109 years ago, and fitting extractors was a great improvement in performance. I don't know what they were off, but the local exhaust bloke had them in stock. LPG likes to breathe, so free flowing exhaust and get rid of the oil bath air filter. It was still pretty slow as the motor was quite worn, probably need a new camshaft.

Thanks Gents, seems to be over concerned given many have gone there. Be a few months before it gets done just at planning stage at moment and sourcing, taking my time using TradeMe over here.

Has anyone put a fuel injected 202 in a landie ? they were the blue/black motors that came out late model 80's commodores , would be worth considering if doing a injected gas set-up. not sure on legalities as would possibly need disc brake front as well as ecu for the injectors and timing .

The 186 CID Holden or 3000 Torana engines are well suited to Land Rovers. They are not as thirsty and don't have the same overheating issues as sometimes experienced in 3300/202s. We used to suggest 186-S engines were the best because they were designed/cam'ed for a manual gearbox.

Extractors and changing the cam are recommended.

If you can get one the sump and oil pickup from a HT Holden with the centre buldge it will reduce oil starvation on steep inclines or steep decents which happens with the front and rear buldge sumps of the various models.

Always check the adapter/gearbox interface with a dial indicator gauge for centering and alignment before you re-fit the engine. Some brands and home made adapters fail miserably on the alignment issues.

Agreed wholeheartedly Lotz .I had a 186S with factory headers and a 350 Holley.With the 4.1.1 diff ratio it went well without revving its head off.Stupidly I gave the headers away,

If you're looking at a 12 port head, see if you can still get a yella terra head off the shelf. Can go to bigger valves, ported (make sure you match to manifolds), webber carb is good improvement, with the sump you can also extend it by adding an extra section from another sump.

Fuel injected will open up a whole lot more headaches, lift and pressure pumps (or swirl pots in tanks) & surge tanks, elecrtronics.

..., with the sump you can also extend it by adding an extra section from another sump.
...Make sure you also extend the pickup pipe or the mod will only give you some extra oil volume and you'll likely have oil starvation on either the incline or descent. It will however improve engine cooling slightly.

[clubagreenie]

Thats the primary reason (cooling). As long as you keep the original wall and just cut away some small areas to allow it to drain to the centre pickup area it's fine.

As my 202 now needs a head gasket, im looking at putting a reco yella terra head on the thing so naturally will be looking for extractors and a few breathing upgrades to make it worth while.

Obviously 202s came in kingswoods as well as commodores and toranas, would all the extractors be the same? or will they be model specific?

As my landy already has a 202 in it I will assume that the header that are on there would be standard issue holden?

[Lotz-A-Landies]

Some later model engines had more ports so you need to make sure the header matches the number of ports or at least are designed to interface directly with the change in port design wothout steps and obstructions.

[clubagreenie]

The YT head will be a 12 port design and will be optimised for size. Depending on the source of the headers/extractors you'll need to match port them to some extent.
