EFI onto a 2T

[Baref00t]

I did search, but possibly didn't find everything... Basically I got to talking to some mates on the w/e and am now considering the possibility of finding an EFI kit I can fit to my 2T...

Do people do this, does it work, and how much does it cost? Do I need to go aftermarket, or is there a good donor car to rip EFI off?

[Rodger]

One option for a pushrod 2T:

Redline dual Weber manifold: $350 aprox with linkages and spacers.

Dual Twin throat EFI Throttle Bodies (Weber/Dellorto/Solex bolt pattern): $1000 aprox

Four mid range sized injectors: $150 used

Some form of EFI computer $500

Replace fuel lines and install EFI fuel pump: $250

Labour and materials to wire and plumb up and get it running: $200

A Total: $2450

As for the questions.

Very few if any do it. However it could be a good, fun, learning project and would be something different.

Worth it? Maybe but there are better options and keep drivability such as old school Solexes. If you kept the car long enough you may save on fuel costs

2Ts never came with EFI, (someone will probably prove me wrong and I'll expect that), so modifying anything else to suit would involve some alloy welding. A 2T-G or 3T-GTE EFI (single throttle body) set up could be grafted onto the 2T. Cutting and welding on a different inlet manifold flange.

Option two:

Use the OEM single downdraught manifold and find an EFI unit that, say matches a Weber 32/36 arrangement. Cheaper only by a factor of one throttle body and manifold and all other costs similar.

*ouch*..... tad more money than I'd hoped!

Might just go chasing sidedraft webers afterall!

You could track down the EFI setup for a 3T-EU, pretty rare beast though. Methinks a better option would be a 2T-GEU swap, someone posted details of a complete engine/trans package for sale in a recent thread.

rodger, with that first option, how would you install the injectors?

where would they go!?

[Hurricane]

you can mod a 2tg injection manifold to fit a 2t/3t i did it with using the 2tg twin solex manifold so i could run the solex's, so no reason why iit cant be done with the injection manifold too

i redrilled the holes in the head to sute the stock spacing of the 2tg manifold, and cut of the bottom tags of the 2tg manifold and weld'd them back on to sute the bottom spacing of the 3t.

all the port spacings are the same, its just the water outlet on the side of the 2t/3t head is block'd of but the 2tg manifold, but that doesnt mater, but you can just drill a hole were it is if you like and tap into it, i think?

Most aftermarket Weber style EFI throttle bodies have injector bosses machined into them. Failing that it would be a simple process to weld the bosses into the Redline manifold. You'd need some sort of fuel rail made up for either option.

What Rodger is suggesting is the absolute best option but there are ghetto ways of doing it.

A far cheaper, but less satisfactory, option would be to fit throttle body injection from an early S motor (as found in an SV10 Camry). You'd just need an adaptor plate and some really rudimentary fuel only ECU.

If you were interested in more complexity, then just use the standard manifold, weld in some injector bosses and fit an appropriately sized throttle body to it. You could still get away with a reasonably rudimentary fuel only ECU.

Using a Mega Squirt or even a reprogrammed Delco (Holden) ECU would help keep the costs down.

better off getting a webber downdraught and adaptor on it, very easy and common carbies and will get great power increase.

in regards to going EFI,
I would Fabricate a simple manifold whack a 4AGE throttle body on it, and a MS,
Could be done for under a grand depending on what work you can do.
This wouldnt be Ghetto, it just wouldnt be a nice as the setup rodger suggested which is really overkill.

Problem is you would have almost no noticable gain over just getting a 32/36 DGV
Which with basic skills and carby tuning knowlage which could be done for 200 odd including cleaning up the carb

if you are doing this because you really want to keep the 2T then go for gold. if you are doing it because you want a cheap upgrade then either do the carbie upgrade or swap in a 2tg(eu)

I did make ITB's for 3T with very low budget. I cutted intake manifold flange from original mani and then I welded cutted valve cover to the flange. 2/3T valve cover has the same hole spacing as the head's runners. 4 volvo/saab strömberg's were butchered for the butterflies. Then I turned a arbor for the velocity stacks and pressed the trumpets. Megasquirt with EDIS hardware was used for the engine management.
Total costs were around:
megasquirt 120usd
EDIS hardware 25usd
injectors 100-150usd (cant remember)
used tps from wrecker ~20usd
All the rest was free junk from friends.

These have been in my daily drive for 2-3 years now. No problems what so ever. 100 times beter than original carby and the sounds...
This kind of things are the best, considering what you learn from these while doing. Plus it's fun to do...

But to the original guestion. If you're just after cheap upgrade, Weber is recomended.

I picked up a complete 3T-EU setup (head, injection, distributor, computer, loom) for I think $80 (maybe $100) for Mark (AE25). Problem is they are very rare and thats in NZ, and I think Mark is using it.

Other thing you could use is motorbike injection, just cut of and clean up your runners and than join the motorbike throttles (they hose clamp on with abit of rubber hose

[Hurricane]

how soon you want the manifold? i might mod my 2tg one to fit the 2t and sell it too you if i can be bother'd?
