I did not have a good experience with JUBU - I was involved in the first group buy for the JUBU ECU.

~3psi more boost at 2.8"

Personally I'd get the 10 bolt version that requires a hub as well as you're significantly increasing the spin rate. Lower size than 2.8" requires going through Jokerz (they have a deal with ZPE). This is useful at higher altitudes or if you want to do a bigger build.

Here's my 2.8 and 2.7 currently disassembled.

1) There are TONS running that level, look at the MR2 2GR community. And I'm talking dedicated endurance racecars, not just street cars. Or Hillclimb cars..
2) The Evora/Emira are run at what they are based on what Toyota and Aisin will warranty their engine and transmissions for, not based on what Lotus designed. We who are in the know, have the general failure point for most every part of the 2GR-FE.
3) Yes, and a really shady one at that.
4) There are countless of these, search more. Spero's saga is posted here somewhere, bought a fully built longblock from JUBU, it's not built correctly, JUBU's response is buy their Syvec's ECU to fix errors (instead of correct their work), he did that and had persistent issues. There are at least 3 on-going Emira JUBU Syvec ECU screwed up car sagas right now.

Lets go down the list of all their engine mods.

• Aluminum flaps for oil pan: valid, but you can also do Wilheim Raceworks baffles or go for a Moroso Pan.
• DrySump: not needed unless you're a dedicated RACE car, i'm glad they offer this as no one else does, but there is almost no use case for 99.99% of people.
• Rods: (I own these) They are made by Mahle, you don't need rods unless you're a turbo application or running over 7800 RPM. The more budget friendly option that realistically is just as good is Brian Crower (these are what MWR sells, except at 2x the price direct from BC)
• Pistons: (I own these) They are made by Mahle. I bought 10:1 CR. There isn't really a defined limit for pistons, some people run 650whp on oem pistons, other people have had piston issues at 250whp, this is more of a Toyota issue with the rings. Again, there are many more budget friendly options, MWR has a lot of compression ratios avaliable made by Weisco.
• Head processing: (I hand ported mine) The exhaust ports for cylinder 1 and 6 do indeed have lower flow by a good margin, and the castings can be not great with some ridges. There are some significant casting bumps in the exhaust ports as well. For the price if probably not worth the squeeze. MWR also offers this at a lower cost (DO NOT BUY Ti RETAINERS, and remember their Ti valves are OEM toyota parts at 3x the price).
• Valve Springs: Needed if you want to consistently be running above 7,200 RPM. JUBU's 30% stiffer than stock is in-line with what I have, this is a good rate. Note that you'll need the older style retainers (new 2GRs come with beehive springs and retainers). I have Frankenstein Motorwork's springs for reference.
• Valves: not really needed, they do have benefits though. MWR sells titanium ones (these are direct toyota parts at 3x the price). I have Titanium intake side valves and oem exhaust (note you never want Ti exhaust side for FI applications).
• Rod bearings: (I own these) I went ahead and bought them before taking my engine apart, really not needed. COULD be beneficial at high RPM like mine (8k+).
• Belt drive pulley set: complete bullshit. People run the OEM pulley/bearings at 1000hp.
• Alternator pulley and Water Pump pulleys being light weight and/or underdrive (larger) are build specific and not needed for 99.99% of people. (I have a light weight water pump pulley from NST)
• JUBU Cooling upgrade is just a lighterweight pulley and lower opening thermostat (this is a toyota part) which will get you 1-2 cooler laps on a track day, zero street benefit.
• Short/Long block prices are over 50% more than direct from Toyota.
• JUBU Cams: re-processing of your OEM cams, only +30hp. There are plenty of better options on the market. MWR (re-processed), Kelford, CatCams, Frankenstein Motorworks (basically best on market, I have these).
• HD Driveshaft - I have a whole post about this, seems to be a bad batch from metallurgy issues causing problems. I can get equivalent ones made for around $4-4.5k USD. I am running my own custom Porsche 930 axle setup (this is the same as what JUBU does).
• TVS1900 vs 1740. The largest benefit is from running cooler and lower boost. You can have the 1740 ported (Jokerz or by hand like I've done)
• Charge Cooling Hose upgrade kit.... they're just silicon hoses, no tangible benefit, they look shiny.
• Their fuel system parts are not needed for non-race cars, and many cheaper alternatives.
• Exhaust system, is good, similar to BOE.
• Syvecs ECU..... Yikes. Many horror stories. Stupid expensive. Get Motec or Maxx if you want a stand alone.

The TLDR; Everything from factory will take 600whp. Valve springs needed above 7,200 RPM, Rods needed above 7,800 RPM or turbo setups. 99% of people won't ever need anything else.

If you want near 550-600bhp the easiest way:
Valve Springs (Clam off engine in bay)
Smaller SC Pulley (maybe port SC)
Remove cats via various header options
Intake
Tune

Take that microscope to all the other businesses selling parts.. same shizzz.. they are businesses selling parts.. and marketing parts... W...T...H...??? Am I missing something?

• No, JUBU is not directly partnered with Lotus.
• You don't have to break the law to be shady.
• "I've been a business man for over a decade.." Congrats, so has likely 90% of everyone on this forum.
• "Take that microscope to all the other businesses selling parts" I have in reguards to lotus and 2GR parts. Hence all the callouts about MWR in my other post. I just gave you a TON of information about the platform.
• "show the evidence.. If I see it.. I may agree with it.. not hard." I'm not your secretary, hopefully as a businessman of over a decade you can do some basic research. There are many places outside of this forum.
• Spero's Emira with a completely fucked JUBU engine they built improperly is chronicled on facebook and discord, first hand emails, actual data logs from the syvecs ecu they claimed would fix things, etc. SCCLEKAX2RHB13390
  Here's me reaching out to the dealer he originally bought it from and eventually traded back into saying they wouldn't/couldn't even fix it, (I was hoping to buy it and fix myself).
  
  
• Here's my most recent interaction with Martin though. I went to Mahle directly and got my answer. I have many more dating back years with Martin avoiding questions, support, etc.
  
  
• An MR2 doesn't even come with the same engine or trans, it's a common swap especially for race applications. Again showing your lack of research and understanding. You're taking JUBU marketing at face value.
• "You can't get mad at someone for selling something out of your budget" See signature... lol ~$150k of mods if bought from JUBU.
• "did you see the flywheel pictures posted" This is hasty generalization. I can go find you a blown up flywheel for virtually any transmission or car. JUBU's entire marketing is "xyz happened in this one specific instance, it's a weak point for all cars" Whereas in reality we see it's not. In endurance race applications even.
• As to different cars and different drivetrains... The 2GR-FE is the same engine in every application it's in. It has the same internal parts. It functions the same. It has the same tolerances. If you want a more direct comparison use the Evora. The couple of drivers side axle half shafts that have sheered have the exact same part number as earlier Evoras driving the same power, through the same engine, to the same transmission and axle shaft. As I said it is most likely a bad batch from production that has seen failure, this means it's not in general a weak point. Here's more info on the axles: https://www.emiraforum.com/threads/...s-and-how-common-this-issue-actually-is.6359/
• If you want to learn a lot more about these engines check out Merry Frankster or Marc (Frankenstein Motorworks) on youtube as a starting point. FasTx for some more lotus specific stuff. If you don't want to research and learn, it's your money, do as you will. There's also a ton of info in my build thread on LT, though some is dated now: https://www.lotustalk.com/posts/6267756/

There are clearly people on this forum that had a really good experience with JUBU. You see where I'm going? The MFs flew out to location bro... flew out to multiple people to make sure things were right. Bro.... shady? Remote one on one session tunes? bro... I have some choice words for that BS.

Remote one on one session tunes to fix things they did wrong in the first place, still didn't fix it, and left the customer out to dry*

I was in Europe when I bought my parts from jubu. Including Vienna less than 2 hours from their hq. I asked if they could deliver to my hotel in Vienna and provide me the paperwork to get VAT refund at airport. This would have effectively avoided international shipping and perhaps even… other new expenses that our v stable genius has invented for intl trade. They flat out told me that for anything under $5k they wouldn’t bother. It ended up costing me 500 more net. I called and emailed them a bunch.

That said, the parts are really lovely and I’m very excited to have them installed. I doubt they were well priced but they do seem high quality.

I am not an expert or in the business, just a life long hobbyist with basic DIY skills and a tolerance for bloodied hands

1) "You've put yourself in a microcosm of extremely limited information" a bit exaggerated but okay I won't argue against that. I am pretty busy daily.

2) "JUBU is not directly partnered with Lotus." You sure about this?.. It sure looks like they have some sort of business relationship. I would think you are wrong here.

3) "You don't have to break the law to be shady." Sure.. but you also can't take one person's experience and project that across the whole organization. There are people that have clearly had really good experiences with JUBU.. and they have clearly showed signs of excellent customer service beyond what's typical. That's pretty clear from statements on this forum.

4) ""I've been a business man for over a decade.." Congrats, so has likely 90% of everyone on this forum." You're just throwing numbers out on this... did you run a poll or something .. WTF?

5) ""Take that microscope to all the other businesses selling parts" I have in reguards to lotus and 2GR parts. Hence all the callouts about MWR in my other post." Totally unnecessary callouts... sales is sales man.. you don't have sales.. you don't have a business. A little puffery in sales? Comeon.. let people do business... why don't you call out Lotus for their mistakes???????
6) "An MR2 doesn't even come with the same engine or trans, it's a common swap especially for race applications. Again showing your lack of research and understanding." Irrelevant.
7) "Spero's Emira with a completely fucked JUBU engine they built improperly is chronicled on facebook and discord, first hand emails, actual data logs from the syvecs ecu they claimed would fix thing.." Pull up the S&P 500 or NASDAQ, do some research on lawsuits... By your definition of shady... every big business is shady AF... don't buy from any of them!

8) "As to different cars and different drivetrains... The 2GR-FE is the same engine in every application it's in. It has the same internal parts. It functions the same. It has the same tolerances." Yea.. the engine itself and internals.. yea they are the same... what's your point? The powertrain/drivetrain isn't just the engine....

9) "You can't get mad at someone for selling something out of your budget" See signature... lol ~$150k of mods if bought from JUBU." Admittedly poorly worded on my part.. I didn't specifically mean you.. It was clear you spent quite a bit of money with JUBU. I mean all the complaints of high prices on this forum.

10) "If you want to learn a lot more about these engines check out Merry Frankster or Marc (Frankenstein Motorworks) on youtube as a starting point. FasTx for some more lotus specific stuff. If you don't want to research and learn, it's your money, do as you will. There's also a ton of info in my build thread on LT, though some is dated now: https://www.lotustalk.com/posts/6267756/"
Appreciated.

11) As far as Martin Jung's response to you or the person with the bad engine, wasn't the most professional response. Not something I like to see... However, that could have been advised by an attorney.. and it doesn't necessarily mean an admission of guilt. On top of that, I'm not seeing that projecting across the organization in terms of how customers are being treated.

Yea .. you know.. they do seem to be sitting a little higher than everyone else.. if you know what I mean.. but they've seemed to also show a decent amount of responsibility and care to some customers..

The thing is, though, they aren’t in reality sitting higher. I manage money for one of the wealthiest families in Austria. Dude has an f40 lm. I’m not sitting here trying to bully Jubu name drop Blah blah etc. I’d never even consider it. it’s just silliness.

Just feels like (as the kids would say) a lot of weird flexing.

NJemira85 said:

Martin’s response there is brutal. He won’t divulge the material of the parts he sold, that he doesn’t even make. There’s no way he had an NDA w the manufacturer.

It’s one thing to mark up a product and sell it w flowery words for whatever price the market will bear. Fine. Capitalism.

But to then refuse to be transparent about the specs of said part, idk man.

Not great
