M_Dragan Posted June 13, 2018 Share Posted June 13, 2018 Hi, I'm upgrading to ARP head suds in my next build. Do I have to use a torque plate when having the 2J bored/honed? And should I bolt down the mains? I've heard different things, some saying I don't need it while others say its critical or my pistons will bind up in the cylinder wall from distortion. My power goal is 600hp maximum. Thanks! Quote Link to comment Share on other sites More sharing options...
Nelsonian Posted June 13, 2018 Share Posted June 13, 2018 I will be using one when it comes time to have my 2JZ engine built. http://dsportmag.com/the-tech/head-torque-plate-solutions-save-valves-and-improve-efficiency-in-high-power-applications/ Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted June 13, 2018 Share Posted June 13, 2018 600hp? Absolutely use a torque plate. Quote Link to comment Share on other sites More sharing options...
Geno750 Posted June 13, 2018 Share Posted June 13, 2018 It's absolutely worth doing. You can rent one from Suprastore, and it's a pretty painless process. Just be sure to save the old head gasket to use with the plate. Quote Link to comment Share on other sites More sharing options...

Geno750 Posted June 14, 2018 Share Posted June 14, 2018 A gasket between the torque plate and motor is required. If you've got a new mls gasket use it. The risk there is it getting damaged, being clamped and reclamped later with the head isn't a big deal. Quote Link to comment Share on other sites More sharing options...

I've never used one Quote Link to comment Share on other sites More sharing options...

The torque plate simulates the head. You don't put the head on without a gasket. For that reason, you don't put a torque plate on without a gasket, as it's no longer accurately simulating the head.

I ended up finding my head gasket but I have just a couple more questions for you if you don't mind answering them. 1: what do you clean off the black head gasket stuff with from the old gasket? Scrubbing it with dawn and a scrubbing sponge does minimal. 2: Should I tell my machinist to also torque down my main caps? I've heard from some people that it's necessary.

Geno750 Posted June 24, 2018 Share Posted June 24, 2018 1. I didn't bother with that, we just pressure washed the gasket to make sure no dirt that could pit the head/block was on there. 2. The machine shop that did mine torqued them down. Quote Link to comment Share on other sites More sharing options...
