4a Head on 7a Block???! Options

[Dennisj1]

Hey Guys just looking for some info on a combination of head and block.

Where I'm from we have a few cars with 4afe/4agze running between 13 and 14 seconds on the dragg strip which I find verry cool.

So, I was wondering if my 7afe with automatic transmision can be swapped with the following: 4a (black/silver top) 20 valve head on my 7a block and a manual transmission.

1. Can I first swap the head only and leave the auto tranny?

2. With some modifications like changing sparkplug, intake, injectors, tranny etc (except turbo and nos) would I be able to run between 13/14 seconds on the dragg strip?

3. Would this conbination cost a lot of money?

4. Is the combination of 4a head on 7a block called frankenstine?

Just looking for some ideas, appreciate the help. THX!!!

I was going by manufacturer info. It's much easier to find that information than looking up the TRUE weight of the car and still get my point across.


And the Yelli Celi was much lighter than most Celicas. All of the engine stuff removed like power steering and all associated parts, all of the AC stuff, etc. Plus no moonroof and other fancy things like that.

Well again I am not sure where you are getting your info.
You must be weighing it with your gf inside
