What engine parts to "Build" when adding FI?

[ahl395]

Hello everyone. First post here.

I am buying a 2016 GT in the near future but am trying to see how much money im spending in the aftermarket realm before i know how much of a down payment im putting.

Longevity of the car is my #1 concern, my current (non mustang) car has 275k and counting. However I do like power, for both of these reasons combined I'm looking into installing a centri supercharger (most likely a Procharger). I'm thinking of just the HO kit and running 8 or so psi of boost. So around 500-600 to the wheels and 600 or more to the crank.

Now I've done alot of research and some say the stock block can handle that, some say only for 50-100k miles, etc. For peace of mind I think if i go the FI route I'd like to put forged internals in, which seems like a cheaper option to an Aluminator swap.

My question is what parts exactly have to be changed out? Obviously the pistons, rods, and oil pump gear. But then I know there's also bearings, head bolts/studs, rings, etc. I'm looking at MMR for parts (http://www.modularmotorsportsracing.com/cart/index.php?main_page=index&cPath=4_30_31) and also would like to know a ballpark figure for installation labor for the forged parts, which I assume would be around $2000-2500. The supercharger I'm capable of installing myself.

Thanks very much in advance.

If you're only gonna run 5-600 at the tire you don't need to do anything. Literally nothing.
If you're gonna spin it faster than stock you could do the OPG/Crank gear, but there are tons of cars that don't have it and none of them have broken yet.

Your weakest link will be your transmission if it's a manual. The automatics are bulletproof. That said a manual will still be fine at those levels for a long time it seems.

I did:

Manley H-Beam Rods w/ ARP 2000 bolts
Mahle Pistons
ARP Head Studs
MMR Billet Oil Pump Gears
MMR Billet Timing Gear

Handles over 8K RPM and well over 800HP (it is making 1,000ish)

LOL..You yanked the engine and sent it off,smart move if its a "shop car"
Shop cars look bad when they blow up at the drags :cheers:

I ordered my Whipple,MMR Oil and Timing gears at the same time
so i can knock it out all at one time..Ill hope the rest hangs out for now

Is your block sleeved as well?

Did you go oversize on the piston bore?
If so how much ?
Going to build the stock block that lost a piston in the Hellion car and was planning to do the same as you .
Do the Mahle pistons have any advantages of the Manle pistons that I can get as a package at MMR for $1350.? Getting the Manhle pistons and Manley rods comes out slightly cheaper .
I have an alluminator short block (11-14 and yes it fits and works perfectly despite what ford racing initially said )now in my 15 Hellion car and a bullt MMR long block in my 12.
I think the engine in the 12 may be a bit noisier but it may be the fuel regulator(and othe race car noises)or just that the 15 is so much smoother (although the block is 11-14)

I don't plan to raise the rev limiter no.

So you think 500-550 rwhp from a centri will be ok on a stock DD engine for 200k+ miles? Assuming a conservative safe tune.

I also plan to put in an oil cooler so perhaps between the Procharger and cooler I should put in the upgraded oil pump gears, thoughts? Seems labor to install them would be around $1000?

A stock DD motor might not live 200k miles, let alone one with a SC. Burning the candle brighter reduces it's longevity. It's not impossible, just improbable.

I agree! Plus, I doubt even a built engine will last that long. I upgraded the opg and timing gear so that I wouldn't have to worry about those when taking my engine up to around 7500 or a little higher. But, I'm going to stay with the stock block and heads until something breaks. I don't see any reason in changing the pistons until they go. If and when that day comes, I will be ordering something like this with GT350 heads http://www.modularmotorsportsracing.com/cart/index.php?main_page=product_info&cPath=65_70&products_id=528

the built engine for sure wont last that long especially after I'm done trying to throw 1200 horsepower through it:lol:

:lol::lol::lol:

Yup, if I build a engine, I'm going all out and see how much boost this Whipple can dish out

 

[ahl395]

Alright thanks for the replies guys.

I'll probably go ahead with the Procharger and the oil pump gears. How important are the timing gears? I haven't read much about them going bad.

I think with the proper maintenance and not beating the crap out of it I'll be able to get the mileage out of it that I want, if not it'll be rebuilding time and I'll stand corrected

I second that! :cheers:
