I'm thinking of buying some pentroof manifolds and wanna swap the 3bolt greddy td turbo flange for the 4bolt t25 flange

 

How much do you think it will cost for a company to weld on a new flange?

 

Before you say they will crack ect I would add extra bracing ect and also make a mount to take some of the weight of the turbo

why bother, just buy the MSP cast ones

Read some great reviews on them and seen some flow charts they flow a lot better than most manifolds on the market, plus read that they haven't had one complaint of them cracking yet?

you should of jumped on the group buy for the AMS ones as there the same as the MSP but around $300 cheaper

Well been offered these cheap so would be rude not too

how old was the review?

 

they were the best option when all the aftermarket manifolds were tubular and prone to cracking. MSP designed a log style CAST manifold that flows extremely well and will never crack, AMS make copies of them.
