2F Versus a 3FE

[Landpimp]

stock 2F is like 135HP
stock 3fe is 155

not a 50hp difference

and your 2F is built so its prolly pushing the same as a 3fe.

3fe is "suppose" to be lighter and more compact..................LOL

I was thinking another 50 hp would nice for driveability, but this won't be my dd. I have been working on 2F motors for a long time as well, so I know pretty much all the in and outs. I have done some work on the 3FE, but not nearly enough to know all of the quirks. I think the 2F has my vote as well.

If you are wanting to do it to gain fuel injection I would look into TBI on the 2F the 3FE is an ok motor but not worth the headache, IMO

I agree. Keep the 2f (especially since its built) and tbi the thing. I've heard nothing but good things about tbi'd 2f's and my f is running like a dream. The system is simple, cheap and fairly efficient (moreso than a carb). All the advantages of fuel injection without the electrical nightmare of a 3fe. If it's a project you want then go for the 3fe- great motor but IM(very)HO not worth the trouble.

Not trying to hijack the thread - but would you go with a TBI kit, salvage parts or something like Holley setup for the heeps on the 2F. We're almost ready for a motor for the girls '66 and were considering a 3FE, but maybe not-so-much now.

The reason I was looking at a 3FE was the fact that Toyota Engineered the motor to be a fuel injected system. The problem with the 2F is it obviously never was intended to be fuel injected. I know that people have gotten the 2F running right with fuel injection, but I think there is a lot of grey area with the injection kits. With the 3FE, at leat you have the backing of Toyota engineers who did a pretty good job of converting the 2F to fuel injection, thus the 3FE. I was also wondering with the 2F injection if you can really tune the motor right. Does the original 2F cam do the job, does the motor breath efficiently enough, is the spark hot enough, fuel delivery needs to be modified, is there a large enough timing range? These are a few questions I had about the 2F and fuel injection, but I have not done all of the research because I felt if I was going to go fuel injection I would just go with the 3FE.

Sorry about rambling on, but I hope this helped

LandPimp, I didn't know that there was only a 20Hp differenct between the motors. Again, more reason to stick with the 2F. I was wondering how to post pictures, I thought I would throw a picture of my motor up just for fun.

I guess maybe in my next project I will do a Canadian FJ45 Truck with the supercharged 1FZ-FE. That I believe would make for a useful and fun project.
