FFTEC Engine Build in Progress

I'm not trying to be a dick, but you basically said JE pistons are the best and then later revealed that's what you are using.

I didn't say they were the best? They have the most information about asymmetrical pistons as they were one of the first to bring asymmetrical pistons in an off the shelf flavor. This is why they were referenced in this thread.

I personally was going to use Manley for our custom pistons but they don't offer asymmetrical machining. Second choice was Wiseco but their lead times on custom pistons are horrendous. JE was 3rd choice because of cost, but their lead time on making a set fit the bill so that is the route we took. CP was never in the game.

 

[dragonacc]

Its the feeling I got.

I like both companies but I think its going to be a while before you can post in each others threads without sounding like you are trying to one up.

I'm glad to see Maperformance is following our build thread. We appreciate that you've acknowledge your incorrect statements about our product offering, and have corrected yourself.
:cheers:

and now back to the build thread...

Adam said Manley doesn't offer asymmetrical machining, but your pistons are asymmetric Manleys. Did you do some machining yourself? And just to clear this up, these are EcoBoost pistons and not the MZRs, right?

That's a Manley MZR piston. The other side is full faced. IF FFTEC machines the other corner of a similar piston to even it out I doubt its going to affect the strength of the piston. Those pistons also have the same type of support running through the middle like the JE ones.

BTW, I'd call that asymmetric personally, maybe just not to the extent of the JE ones. Further, who cares if FFTEC machines an OTS piston to their specs. You think Manley doesn't do basically the same thing to change valve relief sizes etc?

 

[Juben]

Why do you seem to be defensive? If you aren't, then forgive me, but I'm just trying to get some answers for myself.

There's the thing, I'm going to throw pistons and rods in mine over the winter, so I'm asking questions which I'm curious about. I would rather have a piston designed specifically for the EBM, however, if these would work good anyways, then it gives FFTec an opportunity to address my question and tell me the benefits of their choice and why they chose that specific piston vs. maybe a clean sheet design for the EBM.

I know that you're a big fan of FFTec, but I'm just asking questions...not throwing shade.

 

[dragonacc]

Well I might sound a little defensive because this thread is literally about my engine. But I'm not upset so sorry if that's how it came across.

I would like to add that FFTEC isn't big on posting every single detail of their work BUT if you really want to know details about why they do things a certain way they will answer those questions if you email or call them. As I mentioned earlier they have answered a ton of questions for me. :cheers:

Juben, you're a gentleman and a scholar!

These are FFTEC Spec'd MEB Pistons.

Toyota did not offer the Supra with a LS9, High Rise Intake Mani, Twin Turbo, Turbo400 Transmission; But, we've got one. Well, building one.

---

Nissan did not design the 240Z with an RB25; OR to operate with LS2 Ignition coils in a COP configuration. Alas, we've produced that as well.

:shrug:

Our intention in this industry is to do the impossible, with things that "don't exist".

We design, build, test, and then produce products that work.

We've got the technology and expert staffing to build unique --otherwise unobtainable-- Not-Off-The-Shelf types of chassis', turbo systems, engine assemblies, etc., and we make the most of our teams talents by bringing the "impossibilities" to market.



I believe we embody the principals and the reason the motorsports industry exists and thrives within.

Question... Who really cares if they are truly Asymmetrical or not, for the power this owner is looking for it won't affect much at all. Manley makes a Very nice piston, very good value for the money spent, and someone has further machined the piston. The piston does look like a MS3 piston, but without bolting the head on a block and molding the combustion chamber with the rod and pin in place, and sending it off to the desired piston manufacture, who knows if it matches the EBM chamber or not?!?
Personally, I couldn't tell you if it is a good design or not.

What I can tell you, is, I appreciate FFTec and the owner of this set up sharing it. I'm sure this set up is going to make good power, more power then I have, that is for sure......

Thanks for posting

Update!
Progress is rolling along. Every time I install another part on this engine I'm reminded that it's going to make power more easily than our shop car.

And our shop car has made excellent power. During the course of testing our shop car has set multiple records and raised the bar repeatedly. It's been through extensive durability testing including hundreds of full throttle dyno pulls, daily driver duty, extended trips from wet coastal climates to scorching arid terrain to freezing 7000+ Ft elevation. It's the only aftermarket engine for this platform that has a proven track record to back it up.

Here's the next one...

The headgasket was set in place, it's an excellent multi-layer steel design

The cylinder head was cleaned and prepped, the headstuds were prepped then installed the head with cams.

I prepped the oil pump so it primes easily. It has a nice rotor design! It uses a small diameter rotor to reduce cavitation on the suction side, but keeps oil volume up by lengthening the rotor assembly. The pump sits low in the block to reduce cavitation on the suction side.

 

[dragonacc]

Thanks for the update Dave. Head gasket looks like a nice design, far cry from the last one I changed on a SBF. What are your thoughts on the durability of the oil pump? I know it's a weak link on the 5.0s but this one looks beefy.

Stock, FR, or custom cams?

Stock cams. The FR ones won't be out until the end of next month if they actually ship something on time. I also didn't want to go through the expense or be the one to experiment with custom grinds.

Down the road I'll revisit the top end of the motor.

Great stuff David! Just wanted to stop in and say that myself and a few of my friends met a friend or family member of yours this past weekend at Costco in Fremont. Can't recall his name but I think he was a manager there. We were having a small meet in their parking lot. Anyway, keep up the good work!
