Thinking about doing the maxbore thing for reliability cold starts ect oh and the money. Let me know

 

Depends on your motor mods. How bad is your current TB choking your motor. On a built 2 liter motor- maybe 7-10hp. On a bolt on type stock motor 1-2 hp if any at all.

 

1.8 moderate build
got some oil burning (1 quart every 2k)problems had good Ring gaps during build have you guys had any problems like this.

 

How did you go about breaking the motor in? And what grit stone was used by your machine shop for the finish hone.

 

kept it out of vtec for 2k, then dipped into it but not abusive I don't think but these things were not designed to go 8500+ so I was just wondering if it was a regular thing. I am probably not going to pull the motor unless it gets bad.
The car runs a little cold so it might be then that its burning but I am not sure cause its not allot.

 

All i can say to you is max-bore does a hell of a job.

If you beat on it frequently at 8,500rpms+ then its GOING to use some oil. Period. Do a search on it, you will find the R owners have the same "problem". Honda released a bulletin on it stating it was "normal" for the DOHC Vtec engines to consume some oil with extended high rpm use.

 

do you guys have the max bore site link again?

Its a safe invesment mine came out perfect, 69mm tapered to 65. (b16)

 

I had mine bored to 64mm. Its a work of art!

 

didnt he use to have a chart on his website that said the size of each TB and then what he bored it to?

I've been searching for an hour and cant find the info1! wtf!

 

Off the maxbore web site and also an e-mail he sent me.
I havent gotten mine back yet but I am looking foward to it.
{I can convert your First gen JDM B16 throttle body to ITR specs
I can convert your non VTEC integra throttle body to ITR specs
I can make your GSR or DOHC Civic Si throttle body to 2mm over ITR specs
I can turn your ITR throttle body to a massive 65mm and taper out to 70mm
