202 to v8

[JackHopkins]

Hello all. im considering at this point instead of doing up my 202 of putting in a reco 253 or 308? i was wondering what sort of cost this would be along with a rough list of the things that would need changing and replacing. any help would be great. i know i could prob go get a v8 van for the same price or cheaper but i am kind of attached to mine lol

You will have to change the gearbox, exhaust, radiator. Depending on which gearbox you fit you can get away with using your original tailshaft and diff ( till you brake it) then you'll need a ten bolt diff. You probley should fit v8 springs as well for handling but you can get away with your originals for a bit. I would buy a wreaked stato (WB or HJ to HZ) and use it for a doner vehicle you could even convert the diff to fit if keen.

What is it now? 202 manual or auto, column or floor? I assume it is a HJ?

[JackHopkins]

its currently a red 202 with M20. and correct its a 75 HJ.

I WILL be corrected on this, but change the bell housing and clutch assembly to V8.
Radiator, Exhaust and that's about it...
(Getting ready for what's wrong with this)

Gearbox input shaft will be the wrong length, so you'll either need to get a v8 box or have yours rebuilt to suit an 8

Assuming it has a proper HQ-HJ rat-trap clutch setup:

Change gearbox input shaft and cover to V8 M20, or get a V8 box.
The clutch setup is the same for 6 and V8 except for one bit - that bolts to the bellhousing. So you need to find one of those.
Get a HT-mid HZ 253/308 to aussie 3sp or 4spd bellhousing and clutch fork.
Complete 253 or 308 with HQ-WB sump and pickup plus HJ V8 engine harness (might have to make the harness yourself from the 6cyl setup).
HT-WB 253/308 flywheel and new clutch kit with correct throwout bearing and carrier.
HQ-HZ viscous fan.
V8 radiator and fan shroud.
V8 HQ-WB ute or van diff.
Tailshaft from a HQ 253/308 Statesman or HQ-HZ 253 any box or 308 manual wagon or HQ-WB 253 any box or 308 manual ute or van.
HJ-WB V8 throttle cable.
All radiator and heater hoses and clamps to suit.
New exhaust.

The other alternative is to get a mid HZ-WB, VB-VK 253/308 aussie 3spd or 4spd bellhousing and run a mid HZ-WB V8 clutch pedal and cable. WIll need a hole drilled in the firewall for the clutch cable. Requires a different throuwout bearing and carrier in the clutch kit.

Or it might be bettr to buy something like this and sell off what you don't need. You can use everything off this car from radiator through to diff and exhaust. If you are lucky it might be a later 1978 with the right clutch pedal setup.

Buy a complete running donor car.

Swap anything that looks different.

Sell donor car.

Guys,

I have just done exactly what Jack wants to do to my HQ.

If you are smart about it, get on as many forums as you can and do some wheeling and dealing. I bought a HQ tonner for $500 and sold the cab for $300 and the chrome fuel pump for $100. The 253 then only owed me $100.

All I changed was the following:

* I had an Aussie 4 speed, so I just changed the bell housing and imput shaft.
* Radiator
* Radiator Shroud
* Brake Booster
* Front Springs
* Throttle Cable to Cable Linkage
* New Exhaust
* New Clutch & Pressure Plate
* Tailshaft and Diff

I know I have repeated myself to what some of you have wrote, but this is the exact list I changed. Absolutely nothing else. To be honest, I reckon I only forked out around $700. I painted every single componenet (that I didn't replace) and it looks like just out the factory.

Hope it helps.

Oh and do yourself a favour and knock out all the welsh plugs while the engine is out and flush out the engine. You will be surprised what is clogged up there. If you can afford it, its good to pull it apart and do an overhaul.

I also have the original 3 speed and bell housing if anyone wants it. I live in Wollongong just south of Sydney. 0435138978.

You missed the V8 clutch bracket! Why did you change the brake booster?
