Outer Limits 4x4 Board

Anyone got any ideas?

Electronic ignition, extractors, 2 1/2 inch exhaust and a good tune.

What Electronic Ignition you running Sixty?

I have a '74 F with a 3F dizzy and cressida (84' i am pretty as put it in about 4 yars ago) magnetic internals, ingitor and coil.. not really anymore power but very nice (smooth) as haven't touched it since. The extractors and 2.5 exhaust were the best thing.

Cheers

Extractors & new system are definitely the best bang-for-the-buck mod on these engines. You'll also find that it wil rev _much_ more freely once its done.

I'm still looking at throttle body injection & electronic ignition for mine.

When you find it post up some info on here about it?

many others probably want to know

stick that turbo off the H motor on it - the 3F isn't a great motor to turbo but will probably handle 3 - 5psi ok.

Wanna make me a minifold? Also, does anyone know how much the electronic ignition is worth or where to get it?

will have to have a look and see what the best option is - full custom manifold, modify the stock manifold or build an adaptor. from around $150 for a simple adaptor. you have to add plumbing for air, oil and possibly water.

cressidas are pretty common at pick'n'paymore, probably $100ish for complete electronic ignition - dizzy, igniter and coil.

I might steer clear of the turbo just for longevity and insurance reason. Apart from that, the bidding has gone wild lol. So the cressida dizzi will fit straight in?

I doubt it's a straight bolt-in, I think you have to transfer the guts from the cressida into the cruiser dizzy. I've never done that exact swap but have done a few, there is always a bit of weeping and gnashing of teeth to make it fit.

a cheaper alernative would be to get a HEI kit from dick smith/jaycar - about $70, uses the points to trigger a transisotr ignition, but the points don't wear out because they're only switching a few mA instead of 5 - 10 amps.

Tell me more, tell me more... Someone mentioned 3-5 pounds, what would the carby handle though, that was mentioned when I asked?

Small blower would be easier to fit i recon, just a couple of brackets, and you get to leave your manifolds alone, for those with extractors its even better...

My theory anyway...

On the subject of Injection, I was thinking of copying the idea in the nissan bible, and using the throttle body of an EA falcon. Designed for a 4Litre(ish) engine and relatively easy to graft in with an adapter plate. As I am not in the automotive game I'm still gathering info on what is needed. Obviously one would need the throttle body, computer, harness & sensors. Is this a realistic project - or just too much agro ??

Yep thats the way I would go.
Stuffing around with the timing would the biggest thing.
I did a heap of research on this and in the end found a 4.5 litre 80 series engine/gearbox at a cheaper price then the EFI conversion would be.
Altho, I wanted to turbo the old girl (had another 2F to go in) as well. I made the manifolds and all but I went the MPI route with an EF top half of the intake and made my own bottom half.. pix attached bolted to motor, i had it welded up after this pix but still needed die grinding.. Now all just sitting in the shed - 'o well

Don't you guys down under get the 3FE fuel injected engine? How hard is it to swap the induction system to the 3F?

actually i looked at this as well and there are a few floating around in OZ still operating in the early 80 series, but very rare as wreckers want an arm and a leg if they have them.. only ever located one that was for sale after months of searching and i think the dude wanted 1K for it.

I didn't go any further as the ports are a different shape to the 2F, prob is a good option if you can source it cheep enuff.
