Larger Throttle bodies...?

TypeOne · 10-26-2011, 05:47 PM

It would help for sure, but that would require testing to prove. I deal with 4 cylinders engines all day and I have seen 10%whp gains on our dyno with tuning from upgrading to a larger throttle body... 64mm to 70mm.

I'm not sure what the diameter is on the stock Z, but I could almost bet there would be some positive gain there.

A 64mm throttle provides enough air for a 2L 4 pot @ 225hp (factory throttle on Civic type R) I picked up 5hp with a 70mm.

So the throttle on the Z would have to be like sub 60mm to choke the 1.8L 3 Pot on each side

I'll try these as soon as I buy their $14k brake kit, $7k exhaust, and $3k strut tower bar.

Actually they are the same and arent the same

The GT-R can be bored out much larger than the 370z ones. Max bore on 370z is around 64-65mm. GTR around 70mm

ps: 4 year old thread lol
