The car is currently at Jotech Motorsports. I'll update this post as the build goes on but currently the power goal is around 600 WHP and 520 WTQ. The horsepower might go up since the original power goal was just 550 WHP but since I am now having to do some engine work we might be bumping up the power since we now can. The torque is pretty much set at a max 520 WTQ because of the clutch I have.

Congratulations on the build, might want to address to heads if you ever plan on bumping the power up. Those power levels I would of staying with a stock block if you’re not racing the car.

isayimandrew

Address the heads more than what Jotech is providing already? And I won't be racing the car. The only reason I was actually upgrading the pistons and rods were because when we did a compression test, we found out cylinder 1 was at 140 PSI while the rest were around 180-200 PSI. Decided to add the closed deck block mod from Cylinder Support Systems and Jotech's solution for helping with head lift since we were already in there.

Spooler

Not sure what Jotech's solution is but that will be an issue if not done correctly. If you stay around 650whp you should be OK. Since you are limited because of your clutch, I don't think you will have a problem. Get greedy and it can cost you.

isayimandrew

I see. Jotech's solution is to use upgraded head bolts (1mm larger), the ARP main stud kit, and machine heads and block to accept the larger studs. There might be more that I could have missed from when I spoke to them about it. Definitely not trying to get greedy on power. 600 to 650 WHP is something I'd be extremely happy with. I'm not planning on going past that number anyways since for me anything over that is excessive (even though 600 to 650 is technically excessive for street lol).

Sounds like fun! Good luck with the build

Upgrading to a larger head stud isn’t ideal, there isn’t much meat to justify it. You want better clamping load unfortunately some form of on rings or step decking and fire rings needs to happen. Closed deck will not add benefits to sealing the heads. Like spooler said you get greedy and you will be building another motor, ask him how he knows

Spooler

Thanks for reminding me A-hole....

Elmo370z

😂, let me
Rephrase it, good read his thread.1- 160pages

isayimandrew

I gotcha. Yeah definitely not going to get greedy! I'd rather be conservative and relatively reliable rather than chasing a number.

FrankEtier

Nice setup. What part of Texas are you in? I know Jotech is in Garland but are you in DFW?

thanks! and yeah I'm in the DFW area.

Congrats on the build. What boost and fuel are you on?

I won't know what boost levels I'll be on until later when Jotech starts tuning. They just pulled my motor to send it off to CNC Werx last week so I am expecting everything to be done hopefully around mid/late Sept to early Oct.

For fuel, I'll be running anything between E85 and 93 with flex fuel.

Are there any others who is in Dallas area?
