How much should i spend to get it bored to 67mm?

 

To get it done you should spend around $75 to $100 depending on the shops labor hour.
It takes us 1 to 1.5 labor hours to do a bore.

 

I can do that too. I planned to make a new thread so Im not hijacking the thread. Been very busy at the shop. I will look for it on the dynos database when I have some time.

All the best,

I'd like to check those dyno's out also.

 

dyno or better yet flow bench number of before and after.

dyno can be misleading since it can't be replicated as far as time and temperture wise

 

I had mine done by DH racing in Las Vegas. I believe that he had dyno charts of an S on his site. I went with the 74mm taper and he port matched the IM. I want to say it was around $400-500 with the new TB, Port Matching, new gasket and bolts, flow tested, sensors adjusted, TB mounted on the IM when I got it back. He was hard to get of hold of, since he is the one doing the work in his shop. Here is a link to my pics, and yes one of the photos has the OD of the factory throttle body in the ID of my new taper 74mm. I noticed better throttle response, but I do not have charts to prove.

look under the facts section

 

$75-$100 is cheap, but if you want it welded, i'd expect to pay more.

here are a couple i did at 70mm compared to 63.5mm



i also cleaned up the casting seams at the customer's request:

 

Nice work how far in did you go with the weld?

 

thanks. i welded around 1/4" to 3/8" probably. but it doesn't even need that much since it is only seeing a bit of air around it. the tb mounting surface has to be faced afterward, and the port cleaned up a bit to make it look nice.
