Engine rebuilt cost

[steve78]

I was just wondering what a ball park price would be to rebuild a stock 03 Mach 1 engine. Right now it has a Vortech V-2 with the intercooler and puts down 430 rwhp 400 rwtq with 11 pounds of boost. I want to build the engine for 600 rwhp so I was thinking of forged pistons, rods, and crankshaft. I know that the engine bores need to be machined but From what I understand that's all that needs to be changed for the rebuild, if there is more that needs to be done please correct me.

I normally take my car to Granatelli motorsports for all my work but they want $10,000 to rebuild it, that just seems really high to me. This will be done on an auto trans Mach 1.

are you having the shop pull the motor and reinstall?

its going to be quite a bit more than the rebuild on a manual car due to the crank. Obviously theres a ton of variables but youre probably at 2k or more depending on crank, rod and piston choices alone. Not getting into ARP fasteners, machine work, bearings, rings, gaskets etc...doing it right would be updating basically all the timing stuff, billet pump gears if you go that route. The heads will probably need some touching up (exhaust seats, valve seals, valve job).

it gets expensive in a hurry, especially if you arent doing the removal and re-install. 10k isnt that outrageous depending on what you were quoted

Yes the shop would do everything including pulling the motor and reinstalling. They said just pulling the motor would be $3600.
I guess that's a decent price then, now I just need to think about if its worth the money.

If you want to use quality components for the rebuild, $10,000-$11,000 would be a safe number. I went from the stock engine to a 01 Teksid block, Kellogg stroker crank, Manely H-beams, Diamond pistons, stock 4v heads rebuilt with upgraded springs/retainers, and all ARP hardware. Including the cost of parts, other stuff as well that was replaced while the engine was out (i.e. power steering pump and alternator), all the labor (machine shop included) and the dyno tune afterwards it ended up being a little over $11,000. My advice would be to not go cheap and find a shop that knows what they are doing when it comes to the 4V engines even if they charge a little more.

$3600 for pulling a motor?!??

 

[DSG2003Mach1]

3600 is quite high to just R&R a motor. @ $90 hour shop labor thats 40 hours. Im a moron at home in my garage with no lift and can beat that. I wanna say I recall seeing people saying 1200-1500 was about right

Ya I definitely want it done right so I think I'll hold off on the engine rebuild right now since I'm still running the stock transmission and was told it can only handle around 350ish rwhp so that would probably be the best thing to do first before the rebuild. Plus I'm pretty happy with 430 rwhp at the moment, I left a 2015 Mustang gt in the dust the other day hehe.

I was going to go with the LenTech Street Terminator AODE/4R70W and a new torque converter. My mechanic said that my Mach 1 would be LOT faster with it, obviously not more HP but faster.

My engine build was around $8,500. ARP everything, billet gears, the only thing i went cheap on was the rods (boss rods).

I called GTR in Rancho Cucamonga and RET in Downey for a est on doing the top end on my Mach, they were way cheaper on pulling the motor,
think GTR was $1600 and RET was a little more?
MMR in Camarillo had a special on Forged Short Block rebuilds
