TB42 GQ Carby

Post by challenger »

According to my mechanic, my TB42 carby needs a good overhaul.

Do I spend the money getting the carby fully reconditioned, or do I spend a similar amount upgrading to a TB42e fuel injection setup from a wreck (ie. manifold, injectors, ECU, high pressure fuel pump etc)?

Has anyone done this conversion before, and if so, any traps?

I am running petrol only.

Thanks
Dave

This place in Sydney will send you a carby kit for around $53.50
Thats nearly half the price of repco, and lots cheaper than an efi conversion :D

Whats your mechanic quoting for a 'good overhaul'?

You would have it on gas well and truly (second hand kit) by the time you got all the bits for efi. And its a fairly big job for little gain in power and economy. someone on here had a LPG tank converter and mixer straight off a patrol for 400bucks. I nearly cry in sympathy when i hear of blokes still running straight fuel.

I have a kit in the shed. Considering I maybe do 50k's per week it hasnt been worth the effort of installation. Now looking very worthwhile.

EFI conversion using TB42E gear would cost you at least $800 from the last time I looked it up.

Look up Bru21's thread on installing cheapo DIY single-point EFI using parts from an EA falcon. If I weren't on LPG I'd be doing this just for kicks, apart from better fuel economy and performance.

... but having said that, just recoing the carby is cheap, relatively easy, and should be pretty effective.

cost me $45 for bursons generic kit that was on there list to "suit GQ" took us around 3hours and nearly half a slab (shows you how quick we work) to replace all gaskets, plunger, both jets, clean the throats and lube all linkages, fit an extra throttle return spring and get it back on the car and a dodgey tune by ear to get me to my mechanics.
and suprisingly the gaskets did fit good :P

the only thing the kit was lacking was a new float, which if it has been on gas for awhile will need replacing too... mine was cactus.
