I just got a airesearch m10 the exhaust is .63 and intake is .48. My question is how to tell what flange it is t25 or t3 and what kind of downpipe flange will i need or will i have to fab one up?

And how hard is it to rebuild one of these?

 

Welcome to HMT Alex

 

t3 flange holes are 1.75" & 3.375" apart
t25 flange holes are 1.575" & 2.870" apart

 

thanks for the welcome and the info. Any idea what bolt pattern the exhaust outlet.

This is going on a stock rebuilt honda d15b2 to push about 170 HP While i build a d16 for over 200.

 

cant tell from the pic. is it a 4 bolt or a 5 bolt flange.

 

5 bolt one of the studs is still in it on the lower right

 

thats an odd outlet flange. ive searched a lot of sites and i cant seem to find a match for that flange...

 

i seen a nissan gasket on ebay that looks like it almost fits but no 100% sure.

nope. thats not it. the one side has three holes very close to each other which is what makes it odd.
