Exocet EFR
 

Finally got my frame bolted to the miata chassis today.

The original plan began with an Artech manifold and downpipe for the EFR, but it doesn't fit the Exocet (not Abe's fault).

Only about 1/4" clearance here (less if i clock the housing in either direction), and the wastegate interferes with the "hood"

But atleast the downpipe fits I guess

So now I have to scrounge up a few posts to offer up the combo to another loving home.

I sent an email to Abe to see if he thinks just the straight log manifold would work, I have a good bit of room to work with just not where this manifold ended up putting the turbo.

TSE manifold might fit it. This way you could keep your turbo.

I have a SR20 T25 I'll trade you straight up ;)

Looks like you just need a different manifold design to have the WG Actuator clocked 90*. Is that Rhino liner on your floor pans? Looks nice! I am just using some skateboard grip tape on mine for cost & time savings.

Is the front on stands? It looks like it's sitting really high.

IMO, why not try and see if the TSE unit is any better :dunno:

Though I do <3 Abe's work :)

I may look into just doing a pie cut on the manifold and rotate the flange a bit, which would move the wastegate and bring the turbo closer to the block. Then I'd have to modify the downpipe also. Seems better just to start from scratch.

The floors and front bulkheads are rhino liner, I was going to have them powder coated and use the grip tape but the guy did it for the cost of material only. came to $100 and it was done in a few hours.

I don't have coilovers yet so I have 2x4s supporting everything, it does sit a little high like that.

Thought about it, but it looks like it puts the turbo in about the same spot vertically.

Negative,

Moves it forward and up away from that strut area :dealwithit:

Not sure with the exo though, you seem to be the first as far as I know :likecat:

Thanks for the pictures, but looks like the wastegate will still be an issue. Gives me some ideas tho.

missed your post earlier, I'm determined to use this turbo...will figure something out

Can you put a level on the WG can and the VVT actuator or otherwise measure which side is higher/ by how much? I have an n/a VVT engine in my Exocet I am building, but am researching future turbo upgrades. I already have to raise the hood to clear the VVT solenoid, but curious about the actuator clearance w/ the TS manifold. Thanks!

My chassis might be a bit different than yours (EU lightweight Exocet vs US Exocet) but I'll try to remember to measure from the flange to the shock tower and the offset this evening (as I have the TSE manifold in mine).

I just checked mine again, and the problem is where the wastegate sits in relation to the "cowl" on the exocet's hood. I think your VVT actuator will sit inside the raised area and will minimize the amount you'd have to raise it.

I placed a 2" roll of painters tape on top of the valve cover and that gave me about a 1/4" of clearance with the wastegate, but way too much gap on the sides.

But after looking at it, it seems like if i just go with a log manifold and put the turbo flange between the front two runners it will fit nicely. Just need to see how it looks with the steering in place.

Do you have the US bonnet or the UK bonnet? The US version has a bigger (taller and wider, IIRC) cowl, but I am not sure it extends over to where the actuator is.

US. I'll try to take more pictures tonight.

ok so now that i'm posting in the correct thread...

It's been a few months, got the new log setup from Abe. Oil and water lines are done, as well as the fuel lines. Replaced the stock pump with a DW200, ID1000 injectors, and a new fuel rail.

Next week I should be able to get the radiator and intercooler mounted and piping done. *ignore the stuff holding the turbo on, just temporary

What's the deal with that valve cover? I've never seen one squared off like that.

It's from a protege

Intercooler and radiator mocked up with zip ties, might make a few adjustments to the piping but you get the idea.

Surprised you're doing all of this in the space of a apartment garage :likecat:

Starting to come together too, the new manifold looks nice.

At one point I was spread between three separate garages, I'm down to two now. Definitely have to get creative at times, but the space has gotten me through 3 bike builds and now the car.

fancy wastegate with a 5psi spring. will run no boost control on just the spring until I get the other block built up and swapped in.
