V1 Joe's 2009 F40 SS/TC #470

The reason the F35 cars can be swapped to the F40 as follows:
Gen 1/2 Ecotecs have two crank-to-flywheel bolt patterns. 2.2/2.4L engines have six flywheel bolts, 2.0L engines have eight flywheel bolts.

The LHU(updated LNF) came with an F40 option from factory. So you can buy an OEM clutch and flywheel for that setup which also works for the LSJ and LNF due to sharing the flywheel bolt pattern. No 2.2 or 2.4 ever came mated to the F40, only F23 and AR5s. And because of their different flywheel bolt-pattern so there is no OEM solution built for the F40.

I cannot say with 100% certainty that there isn't any combination of OEM clutch parts that won't work, but the F40 flywheels are dual mass and appear to be much thicker than those single mass flywheels made for the F23, F35, and AR5. I'm planning on ordering a bunch of clutches and flywheels in the near future so I can then report back with definitive info.

Regarding the engine, so you're saying the mystery engine has flat top pistons, DI, and a sand-cast block? If so, it's definitely a 2.4L LEA or LAF block pistons and rods. LHU is DI, sand cast, dished pistons.

Flat top pistons. DI like an LNF and a smooth block, not foam cast like the LNF.
When I bring the goblin out of hibernation and I'm out and about, Ill take better pictures so we can get this figured out.
Thats the kind of info I need. Much appreciated.

Got to pick up 470 today. Fired right up, drove out of the building and had the typical attention on the way home. '02ish body style Jetta Diesel with a hood stack asking me about it, honda whipping his phone out for a pic or video.
Somethings dont change. Just like blowing off the bypass valve hose right before I got home.

I was told each one of those Lego wheels is 100lbs. Thats a display car made entirely of Legos.

 

[David]

Wow that Lego car is impressive. The Goblin is the best car on the lot.

 

[Desert Sasqwatch]

Lego Goblin for the next display?

Scott would be laughing at this. Don't pick on the twister orange.

Not picking on the orange picking on the Ford part lol

Could this hole be a boost leak? Its the other mounting hole. My brain cant figure out if its sealed or not.

 

[Gtstorey]

More information of where that is at would be helpful.

 

[comegetjoe]

Its a MAP sensor.
Between the top mount intercooler and the throttle body. Its the second hole where a factory MAP sensor would bolt to.

 

[Gtstorey]

My map sensor is on the intake manifold. I think.

 

[Gtstorey]

I guess I’ve forgotten what sensors are on the LNF. It’s been 5 years and I really haven’t had to do anything on mine in that time beyond the ECM replacement. I forgot we had two pressure sensors.

I have a bolt in that hole. Don’t remember if it goes all of the way through. Either plug it or take a small piece of wire and see if it goes through.

But it probably isn’t big enough to bleed if a lot of boost but I’m just guessing.

 

[comegetjoe]

*edit - Yes. Old one blows air easily both directions, new one in the box is dead one way and open the other. Super stoked, this could be my boost leak.

PCV valve.
This is only supposed to blow air one direction?

 

[Ross]

That PCV is a low pressure valve. It may not seal tight when closed, but drastically reduce air movement in one direction.

I agree to see if it goes through or not. I disagree with the second, any hole is big enough to leak boost. Of course, a bigger hole is going to leak it faster but this hole looks big enough to bleed a good bit. This is all assuming it goes through completely.

 

[Gtstorey]

The hole is only a 4-5mm hole. At least I would guess that I used a metric bolt in the hole.

 

[comegetjoe]

Ill get the PCV in, plug up the MAP sensor bolt hole and see how it runs.

 

[comegetjoe]

No change in how it runs with the new PCV, that hole in the MAP sensor flange plugged. I made a trip with the MaF unplugged like its been and it ran better that the trip with it plugged in.
The trip with it plugged in lead to many misfires, pops and bangs out of the exhaust on decel, power reduced after multiple misfire and a hesitation switching from vacuum to boost. Once the engine started making boost it made a few psi and then started misfiring.

Just trying to talk through this, im back to whete I was last season.

Ill try stock coil packs and dropping the gap even further. I think I was at 26 when the plugs were gapped last season.
