Is a torque plate worth it?
I know for high horsepower applications it's a must. My setup is a 11:1 compression NA Sr20de/ve hybrid with big cams and itbs. Have 86.5mm pistons I want to use but being on the east coast of Canada limits my options on sending my block somewhere and no local shops have sr20 plates.
A cheap torque plate runs almost $700 Canadian by the time it gets here, if you were in my shoes what would you do? |

is it absolutely essential? no. is it a wise idea? yeah. it would be cheaper to just get a stock sr20 head, and have a machine shop cut holes through it, rather than machine a new one from a billet. you might also hit up Bardabe, iirc he just had one made for his sr20VEt project |

Thanks for the replies everyone, I do have an extra NA head around so could check into getting some holes cut in that.
We don't have a terrible amount of shops around who do stuff like that unfortunately, east coast of Canada isn't exactly known for its car culture haha. Only have 2 engine shops within an hour drive of me, one said they don't use torque plates on anything except for very high hp builds and the other didn't know what a Sr20 was. Seemed confused on why I'd be building a 4 cylinder when I explained...both great candidates. |

Don't bore holes in a head trying to use it as a torque plate, that is just plane silly.
Most likely the head wont survive you drilling cylinder sized holes in it, in it's cast state anyway.

Meh It's a high commission non turbo build with a standard oversize (factory recommended oversize is .5 mm) Good idea, but for a low cylinder pressure build, I think it will be fine Shoot. The factory never used torque plates when they built all these SR engines (including the DETs) lol. Not saying its the proper way to do it, but it isn't the end of the world as long as the machine shop is capable Agreed I recommend it, but not a necessity for such a simple build I'd be more worried about the inability and inexperience of machine shops available to the OP more than actually having access to a torque plate The fact that one shop doesn't use torque plates and the other has zero idea on SR specs and aluminum block with steel liners, there's a 50/50 chance either shop will screw it up. YMMV |

OP I would do the math to ship the block to the states too proper machine shop. The cost of the torque plate will probably be less than shipping it stateside.
Also inexperienced shops. Tools are only as good as the operators |
