Retrotech Throttle Body Injection. Get rid of that Webber!

I guess this onlt realy applies to my motor. But I need to ditch the std manifold because the desgin is crap. But then it is english. Could get around this and raise the carb to make more torque but the triples looks way better. Plus little or no adjusting once set up.

Yes TBI is good way better than carbs but not for me I'm going for the 70s look.

The 1600 head has the ports tidied up and has 2l valves. Nothing to special. Runs at 10.5:1 compression.

With that compression and a cam she should be very decent. Do you have an ECU?

At the moment its just running carb 32/36 and a quaife cam gear. I have a single 45 I was going to put on, or stuff around with the injection. If I went the injection route I have an AC delco ECU which would work, possiably not the best but I have it.

The engine is in my mk1 escort at the moment and it is pretty peppy. Because I have a replacement nissan ca18det for the escort the 2l will go into my mk2 cortina. The cortina will be an everyday car which I would rather not have off the road too often. If its working on the simple carb now I dont know if I can bring myself to spend the money/or time to go EFI. Would rather mod the ca18det a tad more.

I do however want to have a play with one of my spare 2l heads and Vizzards book. I think the 2l head is a bit better and wouldnt bother with the 1600 one again.

I wouldn't have said way better, carbs set up well do an excellent job and will make just as much power as efi. This was my previous daily driver tail.jpg

It had a 302C with a Holley 600 carb. I sold it when gas was $1.26L 5L's with a cam and a 3 inch exhaust is a thirsty beast!

Nice choice of engine :wink:

The short side radius is where the power is made (or lost) the rest is easy

how hard would it be to set 2 of these throttle bodies up on my 351w ? what sort of ecu ? can u get a fuel only ecu? as i still have a dissy could 1 efi pump supply the 2 t/b. youve got my brain working now . i have set up an efi system b4 in my lc torana [3.8 v6] so could prolly do most of it my self

You'd need to mount them obviously then make a throttle link and bipass one of the fuel pressure regulators or run twin fuel pumps

what sort of ecu ?

Doesn't really matter...

can u get a fuel only ecu?

I think wolf does a fuel only still but the link will work with points and then you'll get fully programable ignition.

as i still have a dissy could 1 efi pump supply the 2 t/b.

Yep, just remove the spring from the first fuel pressure regulator so that the 2nd FPR looks after the fuel pressure.....

youve got my brain working now . i have set up an efi system b4 in my lc torana [3.8 v6] so could prolly do most of it my self

If you've already done an EFI setup this will be a walk in the park

Got any pics of the Torana?

cheers ,when i built that car i think i was one of the first in nz to transplant the commy v6 even the local holden dealer couldnt help me with much . first started to do the job in late 92 and finished in late 93 . full rebuild on whole car took time and heaps of $ was finally redg and certed in early 95 drove it for 2 years without missing a beat then flicked it to buy house. if i still had it prolly have supercharger or twin turbo set up by now as kits are avail in aus now then it would have been scary
