Ok guys i want all the input and advise you grease monkeys have to offer.

its time to put a bit of muscle behind my old girl,(LH SEDAN) shes currently running a red 202 with a collumn shift auto. I want to know...

1. how much should i pay for a decsent condition carby 308 and manual gearbox to match.

2. would it be much harder to put in a floor shift manual with the 308 or a column shift manual...auto not an option!!! and if so what gearbox should i use, and roughly wats the procedure.

3. what is involved in the engine transplant, im pretty cluey but dont exactly have one lying around to go off...do i need to move the engine mounts or just replace them. and what else will have to be moved... i know about the brake upgrade already.

Go and find a standard 308 with 15,000-50,000kms on it (roughly), and an M20 Aussie Four Speed to match. new rings and bearings in the 308, a small cam, and a few other goodies (Quadrajet carbie, roller rockers, double valve springs, electronic distributor... things like that).

Then get some secnd hand "Tri-Y" extractors, V8 front springs, V8 radiator, V8 brake booster etc and install the new motor. Take it to an exhaust joint to get some pipes fitted up (cheap twin 2.5" system with a H-pipe would be fine.

Take it down to VicRoads and tell them the new Engine Number. :)

Floorshift is easier to do beacuse the shifter just bolts ontop of the box, all you need to do is cut a hole in the floor & carpet.

When you actually go to do it, it will be more expensive and time consuming than I've made it sound. But it'll go nice.

id go with an M21 behind the 308,thru the floor like he said^^
if you get an engine and box for 800 bucks just to get things started expect to spend around 800 again on necessities like clutch pedal, radiator,accelerator cable,new hoses, wiring harness extension, and exhaust mods.

once its all mobile then youve got the legal issues to throw money at.

if its all well planned then theres only a month off the road.

plenty of us could/have done it in less but first time around theres heaps of stuff that can take you by surprise.

thanx guys....yer you said it, finding a descent 308 will be the hard part, got another one for you, to fit a M20/M21 should the 308 be a turbo bolt pattern?

also, if any one in NSW does have a descent 308 and any goodies to go with it, let me know....



Cheers guys

You want a Trimatic pattern block. Trimatic/M20/M21/MC6 are all the same :)

Keep your eyes out on eBay, trading post etc.

G'Day,
Sounds like your on a winner with this one dude. Get stuck in and get dirty!

If it does go ahead, I would be dead keen to swap you or buy your column auto steering column complete.

Where are you located?

Personally, I'd try and get my hands on an EFI 5ltr and 5 speed from the wreckers,Ebay etc and drop that in. You could run the EFI with standard computer or an after market one. Or convert the motor over to carbie by changing the manifold and dizzy.
If you went this option you would need to change the sump,oil pick and engine mount brackets as commodore are different to torana.
But the power difference between the EFI V8 and the older style carbie V8's in standard trim is quite noticeable. It just depends on your budget :rockon:

Also I have a VL 308 carby motor sitting in garage, Its got an ACL race kit through it, cam etc. All it needs is a gasket kit through it as it was pulled down to inspect when it got pulled out of car. Was going to keep it as a spare, still might...Who knows..

Hey guys, ive got another question... you guys have been realy helpfull so far.


A friend is selling a slightly worked 308 for cheap, it has a Turbo bolt pattern from what i gather.

What will i need to bolt up a supra 5 speed gearbox (ive turned away from the idea of running a 4 speed with an 8....simply not enough gears).

Also if it does turn out to be a Trimatic pattern engine, will that make it easier to bolt up the supra box.

Please anyone with input let me know...


Also if anyone in NSW is gettin rid of a 308, and isnt asking the moon for it. Let me know.

Either way (turbo/trimatic) you would need a suitable bellhousing. Dellow/CRS probably have something for it. The W58 will turn into mush if you upgrade your 308 beyond 'mild'...best bet is to find an EFi 304 w/ getrag 5 speed.

Hey mate,

It all really depends on your budget as to what the final product would be! By the sounds of things your on a tight budget, but thats not necessarily a bad thing. As Heath mentioned you could find yourself a 308 with a few kay's on it (less than 100 000km will still be a very good motor). For a gearbox on a budget, forget the supra box because you'll end up spending a bit of money as most parts are custom and the box alone will set you back nearly/over a grand... Let alone all of the other parts involved in the conversion.

If you were to settle with an Auzzie 4speed and compromise on your diff ratio you'd get good cruising RPM and performance too. Also, a trimatic is a great alternative and would be easier to fit due to no need to cut holes.

I cant tell you any real life figures, but a good $3k should cover all costs provided you dont go rebuilding boxes or engines as well...

Cheers
Keith

its deffinatly easier to go and find a drivable v8 car or wagon that way youve got every thing yoll need as i have just converetd my old 74 lh from 173 auto to a 253 with turbo 400 (yes i used an adapter plate ) but it was the cheapest way to do it especally when you pick up a hx wagon for 700 drive away from this

I was quoted under $2,000 from dellow in sydney for a conversion kit with reco supra box. I believe I still needed to purchase pedals and flywheel to go from an auto. this was for an injected 5.0 into UC

This is a quote LX308 received from Mal Wood Auto dated Sept 07.

The Supra W58 5 speed is quite suitable behind a 200kw engine but above that the Tremec is the choice

The W58 with all the parts to fit it which includes, New bellhousing, New 10.5�� clutch kit, New Hydraulic Bearing ( pictured in the attachment),New special firewall bracket, New master cylinder and reservoir, Modified clutch pedal, New Braided line, Mount bracket and crossmember, New speedo cable, New slip yoke, Floor boot, Gearstick and knob, this Premium Supra kit will cost you $3545.

The Tremec TKO 500 is a much better long term choice for the Torana, it too includes the same parts list as above. The full kit for the TKO 500 will cost an extra $2430 and If you want a Billet steel Flywheel and ARP H/P bolts add a further $445

Hi
Depending on how well you can sniff around, i got a w58 for $450 with belhousing. It was not the right belhousing so i sold it on ebay for $20 less than a new one from crs. Once i bought a new spedo cable slip yoke and clutch plate for $300 the whole conversion cost less than $1000 and i have used the same gearbox and belhousing with my old 253 and new 304 and havenot had any dramas. Good 308s can be had cheap (out of wb statos commodores) for under $1000 and you can here them going. All project prob cost alittle more than you want but you should end up with a nice car. Good luck hunting around let us know what you end up bying

eddie your 74 lh looks tidy
