Yeah VE plummets after 6500 partially due to the head/cams, but mostly due to the terribad vtcs intake mani.

I will look in to implementing this EBC setup.

are you on the oe efr bcs or using a mac valve like the diagram?

Though I'm sure it won't hurt, the only times I've deemed the above as "needed" was on IWG setups with tons of backpressure (which is what that diagram even says). on free flowing ewg setups I've yet to see any difference.

And tbh, since you're on an MS2 and won't have proper closed loop boost control, I'd probably recommend mbc anyways.

To 18psi's point- the WG ports are the opposite on an internal vs. external gate. I'm using it for 15psi on a 10psi spring- but this was the setup recommended by Innovate.

With a lot of help from Sixshooter, we managed to bleed my clutch fluid (which was fucking disgusting and brought back all the pedal feel) and swap in a flattop manifold and knockoff skunk2 throttle body into the car last Saturday. This had the benefit of also fixing the vacuum leaks I couldn't find. It turns out all of the nuts on the intake manifold studs were hand tight from all of the vibrating. We made sure to use locktite this time. These studs are such a fucking pain in the ass to get to with the engine in the car.

Also, for anyone else who has purchased the ebay knockoff skunk2 throttle body, we discovered an issue. On my unit, the bleeder screw passage was machined too close to the edge of the gasket and resulted in a massive vacuum leak. We had to use jb weld to close up the passage to prevent this from happening. I didn't have time to really tune the car or do more pulls yet but I hope to get to that some this weekend.

I also did a thing yesterday that will definitely be interesting. I purchased this Evora 400 on BAT.

Shit is about to get real. Stay tuned.

Fun times! I was just glad your car ran when we got done so you didn't have to borrow my daughter's car to get home.

Wow @ 400hp. And WOW at depreciation- makes you a smart shopper.

Oh my god.

It's just a daily driver.

Holds enough groceries for one man?

Groceries are delivered by a service, you troglodyte.

One set of golf clubs purportedly fits in the rear trunk. He has monogrammed luggage custom fit to the Evora on order. He just needs to wait for a few more alcantarrrra to be skinned.

I had him pegged as a food snob- you know, likes to squeeze his own fruit before buying.
Fortunately is has a cupholder:

I try to shop at local farmer's markets and only along the perimeter of the grocery store when I have to mingle with the plebs.

If the car can't hold kombucha tea in a biodegradable cup for both myself and my passenger then it's not even worth considering.

You're starting to get just a wee bit personal.

:rofl:

It was loaded on the trailer last Tuesday.

First impressions:

1. Pictures don't do it justice. The car is beautiful inside and out.

2. The shifter is amazing. The bolt action rifle tripe really fits. It's so precise and satisfying to shift gears.

3. It's incredibly stable at speed. This actually makes it feel slower than it is in reality. I did a pull with my fiance and I hit 100 but it felt like I was going 70. When I'm crossing at 70 it feels like I'm going 40. I'm probably going to end up with tickets.

4. The ride is exceptionally comfortable for a sports car.

5. The sound it makes is so so good.

6. The trunk is surprisingly large. Definitely more space than the Miata. Plus it has the back seats/parcel shelf.

7. The radio is way better than expected given how much people complain about it. As a non-audiophile it's exactly what I need and very simple to operate and replace if needed.

8. Rear visibility through the back window is terrible. You think you know but you don't.

9. All of the vinyl on the exterior except for the rear panel looks cheap in person and I'm definitely removing it. I already hated it but you can see where it's peeled up on a few edges and the orange paint is visible between panels on the cowl.

I haven't had a chance to take it on a country road to see how she handles it judge the steering feel yet so I'll update again later. Miata should get some more love this weekend as well.

Good luck, just got finished telling a customer to avoid Lotus, especially Evoras, at all costs. Enjoy!

:rofl:

'Gon have to be a bit more specific if you 'gon make comments like that

I'd love to know more specifics. I'm on the forum a lot and the issues on the 400's are minor. The S1 had a lot more problems then the new ones.

I've only driven an Evora around a parking lot, and am honestly only aware of their clutch expenses. Did they solve either their longevity or labor hours for the 400? The one I drove was also a lifeless automatic. Forget what we did to it, coils and plugs for a misfire? That might have been the v6 Exige cup car. The Elise/exiges like to blow their oil lines off, eat their cams, and in general I think they're built incredibly cheap(sorry, "simple"). For the money I have zero idea why people like them, UNTIL you drive them aggressively and/or track them. I've R&R'd half a dozen 2zzs, I've done a few quite a few oil pan, MCS, and AiM dash installs, brakes, tires, blah blah. Basically been all over them. Lots of poor access, clam removals, and cursing at British engineering. If you've seen any of my other threads, you'll know I hate Nissan, VAG, and you can quickly add most British cars to that group. Brithish cars are quirky, fun, good looking, often great to drive. But cheap (for the customer) or easy to work on (for me), absolutely not.

It was my understanding that the Evora was only a step up in complication from the Elise, hence my concern for your wallet. By all means, it looks amazing, I love the color, you got an amazing deal, and I hope you a long and happy marriage. Please, PLEASE, keep us updated on maintenance, expenditures, and any tips/tricks you find out along the way.

You list some valid concerns on the old cars. The first evora's had clutch issues that also aided in some transmission problems. There were also a host of electrical problems and general build quality issues like rattling dashs and such.

The new evora 400 which was released in 2016 and hit the states in 2017 has been a huge step up. They use a new clutch assembly that seems to have fixed the chatter and gear box issues that many were experiencing on the S1 evora. They updated the shifter which was not too great but had now been lauded as one of the best in the industry on par or even better than many Porsches. They also stepped up the interior quality immensely. It's not as solid as a Porsche yet but it's no longer the complete letdown that it once was.

The clutch replacement is still expensive due to the packaging and longevity is untested. I believe I have one of if the highest mileage example of the Evora 400 in the states. This particular car was a press car and due to some journalist abuse they replaced the transmission, clutch, and flywheel under warranty because shifting to 1st and reverse was becoming difficult. Apparently the clutch still had plenty of life left in it when they replaced it.

There were a few minor issues with the early 400s that have already been addressed by lotus. The AC panel would short and the fans would stay on. This was addressed in a service bulletin. The EU spec seats had a issue with excessive squeaking because they had an empty cavity where US spec seats had side impact airbags. This was addressed with foam by lotus but I don't really need to worry about it since it did not affect US cars. Some people also report some issues with the trunk latch alignment which cause it to stick when trying to open electronically resulting in a need to use the emergency cable release under the rear seat. The only other "issue" which is really just an annoyance is that there is some diff noise at low engine speeds but that's not uncommon in a lot of cars.

I have noticed only 1 build quality issue on mine so far. A trim panel by the steering wheel is loose but it looks like that is the result of prior removal. Some of the metal clips that hold it in are missing which were probably lost by someone.

Looks better without the stripes on the side and front.

I totally agree. Great looking car!

WOW. Helluva car and deal!

Have you done anything with this car since the lotus? lol.


Speaking with psyber and he suggested I check out your thread.
I think I must have missed your data on boost response.... i saw some logs in around page 20 but couldn't extrapolate the rpm your hitting target boost by with the 7163.

I haven't done much to it since the Lotus but it's actually not the Lotus' fault. I'm closing in on my wedding, work has been insane, and there have been a lot of family functions. The clutch rod needs to be adjusted because I don't think its completely disengaging which is causing some low speed issues. The fucking clutch rod adjustment but won't budge so I'm going to have to remove the entire assembly to break it loose.

I was hitting peak boost by 4.5k rpms on wastegate but my tune is not the best and I had a vacuum leak at the intake manifold ports due to loose nuts which has since been fixed. Once I get the timing table right, ebc tuned, and hook up vvt I expect that number to come down a bit.

7163 en route (t4 divided though). wtb:na Miata. 4500rpms isn't terrible for full boost with a larger turbo, especially with room to improve.

I hope you can get it working soon-ish. Having cars sit....sucks.

I think it's pretty safe to say Ryan is probably the first person to actually have a running miata with an efr7163. I'm open to being corrected, but I haven't seen any other 7163 builds get to this step.

considering I have started gathering Miata parts for a car I don't have yet... I expect I wont change that very quickly.

I agree. I grow tired of having a car that doesn't quite work right. I am crossing my fingers that when I get the clutch pedal adjusted correctly I will be able to make quick work of fixing the tune. I want to see what the car can do when it's running properly.

Ahem... I guess my non-BPness doesnt count.

He said running miata...

My car runs I even drove it in the trailer to stick it under the car port to get it out of the garage for while. Heck I even raced it twice last year.

If that's the case, I stand corrected. Did you post in dyno subforum? I'll give it a search tomorrow. I'm curious

he doesn't have a bp, or even a car for that matter. he has a diarrheal tub of turds that ran for like 1 minute lol

(no offense Leafy, but seriously your underhood is the nastiest thing I've seen all year. I wouldn't take the car for free)

lol.
im with 18psi. its a mods list car.

7163 or not, its not apples to apples with the different engine.

It doesnt even have an extensive mods list, lol I realized that when I wrote the for sale ad. It doesnt have fancy shit it just goes fast when the diff isnt broken.

Went to Sebring with the Lotus today. I was very excited because it's been a while since I got on the track and was looking forward to seeing what the car could do. First session was in the 50's and wet from a pirelli challenge team doing rain testing the night before. Grip was hard to find but the car did well and I didn't put it into the wall. When the second session came around I started the car and made my way to pit lane for grid only to hear a loud rattling. I thought something came loose so I took the car back to my garage spot. Once I got out of the car it was clear the noise was coming from the engine compartment and that something was broken. Further inspection made it pretty clear that the supercharger failed and the noise was one of the lobes making contact with the housing. So there went the rest of my track day. I called AAA because I'm a premier member and had them tow the car back to the lotus dealer for diagnosis.

I have an early car and there is a known bad batch of superchargers from edlebrock which resulted in premature failures. I still have a year and 12k miles on the warranty so I'm hoping they just replace it without fighting me on it due to the circumstances. I didn't push the car that hard during the first session because I was learning the car and the track was wet so there is no reason this should have occurred. It probably would have just happened on the street at a later date.

Heaven forbid Lotus would hold it against you to run one of their cars on a track. Where else are you going to fully enjoy the purpose of such a car? Hope it goes well.

A few updates are in order. I have had a few touch points with the Lotus dealer and it appears the problem has essentially fixed itself. The noise was present when the dealer took the car into the service bay. A video clip was taken evidencing the noise and sent to Lotus headquarters. Lotus advised that it could be a problem with the belt and that they should check the pulley alignment, belt wear, signs for leaks in the supercharger, and play in the snout of the charger. When the tech was performing these procedures the noise changed. The next time they started the car on 12/28/18 the noise was gone. They have been unable to replicate it for a week. They have come to the conclusion that the belt was contacting something or was somehow misaligned. They inspected the belt and it shows no signs of wear. The service manager seems kind of stumped but stated that Lotus isn't going to authorize any more warranty work if the problem appears to be resolved. There is no more noise, no engine codes, no signs of leaks, and no belt wear. I asked about whether it's possible the lobes self-cleared and he said that was highly unlikely. If there was a misalignment large enough to cause metal on metal contact it almost always results in the supercharger locking up and snapping the belt. I really don't know enough about superchargers to dispute that but I did have an EFR turbine wheel make contact with the housing and not explode which was apparently a miracle according to Southeast Power Systems. I still have 12k miles and a year of warranty left so I will take the "fix" for now and if the problem presents itself again I will make sure it's resolved. Luckily there was other minor warranty work to be completed so the time away from the car was not a complete loss. My airbag light will be fixed, the spare key is being replaced, and apparently my tire pressure sensors were also an obsolete item and were replaced by lotus with newer units.

Back to miata stuff. As some of you may know, Tony Montana has decided to go the way of the air cooled Porsche which resulted in his decision to sell his miata. I couldn't stand to see such a well built car leave the local group who all had time into it so I bought it myself. This means I will be selling my own car since I do not see the sense in owning 2 highly modified miatas. I will be finishing the tune and fixing a few small niggles with my car over the coming weeks before officially putting it up for sale. If anyone is interested let me know in a PM and we can discuss price and logistics. There is nothing mechanically wrong with the car and I was just getting it to a point where I was going to be comfortable taking it to the track again. When I put it up for sale it will be well sorted and a little prettier than it currently sits.

The only reason this thread had not been updated for quite some time in a meaningful fashion was because Ryan had discovered girls and was courting one. All of his weekends in the last year have been spent neglecting the Miata for her sake :p but the car is strong and will make someone very happy. I would buy it but I just went to the trouble to put a cage in mine and I'm not doing that twice. It's got a brand new 7163 in it and a built engine.

Now hopefully Steve Dallas will buy Ryan's ish!

7163! Best of luck with the courtship and new miata. Bringing the Mrs. to MATG so we can embarrass ourselves and make you look even more stellar?


I've never seen anyone use 'ish' as much as you.

Well... letters 2-4 in my first name are 'ish' soooo.
