i need help with my 4age bluetop

[IKE86]

the chap who had my car before me put some quad side draft carbs and now my ae85 doesnt start at all when its cold unless i put my hand over the carbs. so i was thinking of geting i new fuel injector system with ecu and loom but dont know enough about it so can someone give me some advice on what to do. looking for a cheaper option so i can have a reliable car that starts in the mornings

you'll need:

* rwd inlet manifold
* ecu & rwd loom
* injectors
* all temp sensors, TPS, dizzy etc etc
* more stuff

can be costly but injection is alot nicer to drive as a daily driver over carbied in my opinion. besides, the price you'd get from selling the carb setup would almost cover the injected setup.

where in BOP are you?

maybe using a manual choke setup would help? not too sure on what work would be required to install on a (quad carb?) im guessing its dual twin webers or similar.

unsure if they have the capacity to have a choke installed but essentially a manual choke was there on older carbd cars to assist cold startups, and in the case of my friends old fiat uno, gearchanges as well.

a more expensive (i imagine) setup would be an auto choke, followed by the efi. efi would cost a bit to do properly as mentioned but then you would be selling the carbs and assuming they are weber or dellorto you should get a bit for them.

add new fuel pump, and fuel tank, surge system, possibly fuel lines to the bove list too

is there any reason to keep the bluetop?

could pickup a complete smallport for 5-600 and transplant that, could save some headaches (and possibly create some more, haha)

you'll need to cut'n'shut the manifold, and fiddle round with the wiring - but if you are able to do most of it yourself i reckon you could get it running for less than $1000

which you'd make some back selling your carb engine

edit - you dont need to change fuel lines / tank etc etc. its always talked about, but my bluetop runs fine with all the old 85 lines etc in place. you just need a fuel pump is all! and an efi filter.

[IKE86]

If i did do a transplant can i do it with fwd and can i use that engines ecu and loom or does it have to be rwd ecu and loom.

I am in tauranga.

thanks for your help!

i was under the impression that the efi setup needed higher pressure lines than the carb'd ones

yeah i forgot about the fuel system, but as said your lines are already there so thats most of the problem sorted. i've just taken off 90% of my standard injection setup - injectors, loom, ecu etc which i could get you sorted with. its a genuine rwd loom, fwd ones can be used but they're sometimes not long enough. i might know of a cheap-ish rwd manifold around too and i can give you a hand to set it all up / wire it in if you want.

i was under the impression that the efi setup needed higher pressure lines than the carb'd ones

it needs higher fuel pressure, not higher pressure lines. aslong as the lines are about 10mm for a feed and you got a return line it'll be plenty.

If you have higher fuel pressure, in turn you'll need lines that are capable of handling the higher pressure The hard lines will be fine, just any rubber ones will need to be swapped for EFI hose...I think standard fuel hose has a burst pressure of ~50psi.

[Trls250s]

The factory lines on a ae85 are capable of handling EFI pressure.

Id do what rollaholic says and buy a smallport and sell on the carbed engine if you want to go with EFI. Otherwise manual choke would be the way to go.

Are you running filters over the carb trumpets or it straight atmos sucking?

Not to hard to wire one of these suckers up, and cut and shutting the manifold is also piece of piss.

[IKE86]

another question can you put a smallport intake manifold on a big port
and if you can how?

[rollaholic]

you can, but you need an adaptor plate as the port spacing is different between the two types of head

small port has smaller ports (duh) that are evenly spaced. big port head has larger ports (seriously) that are kind of paired together on either end of the head, with a larger gap between them.

its really not ideal, would be cheaper to just but a manifold to suit the head you have.
