Daytona Racing VQ37VHR Upgraded Throttle Bodies

Daytona Racing Upgraded Throttle Bodies have been modified to accept larger butterflies increasing the area in which incoming air can travel. This means your engine can breathe better which results in improved throttle response and power gains throughout the power band. Includes one PAIR of modified throttle bodies.


Stock TB size 60mm

Upgraded TB size: 62mm


Have anyone purchase these?

Well a few guys have upgraded TBs, and $900 sounds like a terrible deal

Yea the price is very steep. Pretty costly. Yet does this actually work?

I have been thinking about getting this for some time now. I might do it and see how it goes. but I will be doing ported intake and ported lower intake at the same time. then dyno it to see if difference. be next year though

$900 for 2mm........ thats not even 1/10 of an inch

I've been thinking about purchase, but decided to wait until some used one appears on Yahoo Japan auction and grab it with better price. The chipest ported TB among Japanese brands I found is Fujimura which is 700 USD

I use 80mm throttle body and it works great.

Where did you get 80mm throttle body from?

Ls1 motor?

It's from some other Nissan with single throttle body from Japan, so it's a direct fit with the electronic control plug. I only needed to adjust the a/f ratio with the new 3" intake.

andy can you confirm part number? thanks :)

so you basically take 2 80mm tb's and they direct plug and play with the 370 connectors?

I already have 2.75 or 3" I cant remember intakes with no neck downs etc.. that required a new maf mapping and AF change. wonder if I could make this switch and see gains.

Yes, the connectors are plug and play. I machined a spacer so air flows smoothly from 80mm throttle body into the upper plenum. I'll check the part number tomorrow since it's midnight here now.

interesting. have you dyno'd with the new TB's (obviously answers later are fine based on your time)

I wonder if something like the 75mm kit that I found from NWP could work as well.

2 75mm TBs from them are only $130 a piece.
