I have a sr20det t25 (the t25 w/ the square flange) and I'm wondering how close it is to the hf manifold's bolt holes?

 

dont know measurements but prob the bewst way to get those 2 things together would be to make an addapterplate 4.5x4.5 in 3/4 in thick mild steel dont use a hard steel cause u have to drill&tap it

 

I know, I did a dsm t25 set up before and it worked great. I was going to try and weld my own manifold...but I don't think my 85 amp welder will be up to the task. But the square flange of the t25 might be close to the hf! I'm wondering if I might just be able to bore out the holes?
