Welcome to Maxbore throttle bodies.

I specialize in Honda/Acura, but I can bore just about any throttle body.
I also do manifold opening port matching. This is done at the opening of the manifold and does not include runners. Manifolds are not sand blasted, please send the manifold bare without sensors or injectors. Price for Manifold port matching is $70.

Here is a list of the size you can expect to get your throttle body bored out to:

I bore your TB through to the size listed. I do not back taper the TB to make it look bigger ot claim bigger bore sizes.

D series

OBD0 D series to 59mm with a 62mm tapered opening

OBD1 and OBD2 to 60mm with a 62mm tapered opening

B series

OBD0 B series to 62mm with a 65mm tapered opening

OBD1 B series to 64mm with a 67mm tapered opening

OBD2 B series to 64mm with a 67mm tapered opening

Type R TBs (ITR and CTR) to 65mm with a 70mm tapered opening.

H series

US Prelude TBs to 64mm with a 67mm tapered opening.

JDM type S prelude to 66 with a 70mm tapered opening.

K series

All 2.0 and 2.4 to 65mm with a 70mm tapered opening

NO CORES USED! I bore YOUR throttle body and I send back YOUR sensors.

Now some information about what it is I do. First, the throttle bodies are dissasembled, that includes all the sensors and all moving parts. Then the throttle body is sand blasted with ultra fine sand. It is then cleaned and all sand is removed. The throttle body then goes to the lathe, where it is bored, then ported and finally polished. the opening of the throttle body gets a taper that begins at 6 degrees then 3 degrees. A new bigger butterfly is made out of brass. It is then carefully fitted to the throttle body. Once the proper seal is achieved the throttle body is reassembled. The throttle position sensor (TPS) is reinstalled using new screws and it is set to factory specs.

TURN AROUND TIME

Turn around time is three to four business days. This is a good faith estimate and depending on circumstances sometimes beyond my control, it can take a few days longer. This is custom work on used parts that sometimes do not cooperate. Thank you for your understanding.

PRICING

Pricing remains at $100 for Honda throttle bodies and $135 for all other brands. Price includes return shipping and $100 worth of insurance at no extra cost.

IMPORTANT

The price quoted here is for throttle bodies that are sent to me in working order and complete. It is OK if you send it without sensors, but any missing parts or parts that do not belong to the throttle body will incur an extra charge. I can, and do fix throttle bodies, but you must tell me you need the throttle body fixed as well, on top of the boring job.

SHIPPING

You must include a piece of paper with the following information:

Your name

Your return address

Your email address

Failure to do so WILL result in a delay. Thank you.

Throttle bodies are sent back via USPS Priority insured for $100 at no additional cost. I can also ship next day air if you need it, but the cost is higher.
International customers, please email me for shipping fees before sending your throttle body. Email me if you need more information.

Please package the throttle body carefully. A loose throttle body in a box with styro foam peanuts is not the right way to ship it. Protect the TPS as it can be easily broken. DO NOT USE STYROFOAM PEANUTS to pack your items. I have gotten several throttle bodies with broken sensors. throttle bodies and manifolds are heavier than the peanuts and they always end up at the bottom of the box with no protection. I have found that crimpled newspaper is better than styro foam peanuts. Make sure that no part of the throttle bodymakes contact with the inside of the box.

WARRANTY

Your throttle body comes back with a limited lifetime warranty on workmanship. Warranty does not cover Sensors. In order to obtain warranty work, the throttle body must be returned in the same condition it was sent to you.
This warranty will be void if you disassemble, or modify your throttle body in any way. There will be a flat $50 fee for any repairs on throttle bodies that have been disassembled or modified.
