Nerologic

As question states, is there an aftermarket one available?

I searched and got no where, or does any other toyota one work?

I want to see if there is a direct replacement (or something similar) before i spend money on a custom adapter or have my stock ported.

Thanks in advance guys...

The only option I've ever heard of is boring the stock throttle body.

Ya thats what i figured.

Thanks for your input, i am getting a whole blown motor just for the intake manifold and chain cover plastic.

I guess i will just have to bore that one out...

I wanted to ask the same thing. My question is: will the newer V8 engine Throttle Bodies fit on the 3.4 5VZ-FE intakes? What about porting the intake as well?

Nerologic

I doubt it.

The pattern seems completely different.

I ended up having mine borred out to 64mm.

did you notice any performance gains from it?

and how much did it cost you?

Just bore it out yourself. Bore the front end to the butterfly valve (not past it) with a Dremel and various grinding/polishing attachments. No, I didn't notice any gains when mine was N/A so I'm not so sure it's worth the trouble.

You can get quite the intake set up going if you want to gain a little HP and some throttle response:

• Deckplate or elbow mod ($15 or free)
• ISR mod ($6)
• TB coolant bypass mod (been running this one for years - no issues) - $5
• TB bore (Free if you have a Dremel)
• O Gasket mod ($6)

I still have (3) O Gaskets left from when I used to sell them. $6 shipped. Email me if you want one.
