Is the Evora 400 engine Direct injection, Port, or Both? Is carbon buildup an issue?

Does anyone know which Toyota 2GR engine is in the Evora 400 and if it is Direct injection, or the newer direct and port injected engine?

Anyone running a catch can?

My previous car was a 2011 VW Gti and I had to have the carbon buildup cleaned 3 times over 100k miles. The obd would throw intake manifold errors when the carbon buildup was bad.

I do not believe we have direct injection. Same core motor as the S1 Evora. Still run Techron through it 1x/yr which is useless on DI motors.

It's port injection only, there can be carbon build up, but it usually occurs at higher mileage. 2GR has direct injection in some applications, but not for Lotus.

Praise Jesus hallelujah!! Great to hear, because direct injection carbon issues was the bane of my existence in my last car.

The reason i initially asked was because I saw some companies that made catch cans for evora's. I figured only DI engines would have a need for them.

In supercharged or turbo applications the catch can will reduce the oil vapor from coating the inter-cooler as well as the rotors. It is also helpful to monitor the condition of the piston rings over time. As the rings wear more blow by is produced filling the catch can quicker.

Any boosted engine will have increased crank case pressure due to more combustion chamber pressure versus a naturally aspirated engine. Catch cans are good for the reasons stated above, especially if the PCV wasn't specified for positive pressure use. I don't know if the PCV changed for supercharged models or not. If it didn't it may wear out more quickly leading to higher than normal oil consumption.

These motor are the least of anybody's worries. Everything I used to fuss about regarding routine maintenance always has a happy answer. Same with the valves which require no real attention. Makes you want to consider a Supra. Oh wait. Not anymore!
(It's hilarious how many Supra people are bummed that it now gets a BMW motor!)

The car I should put catch can in is my GTI. Cokes up faster than a night at CBGB. Makes you realize that not all new features (direct injection) are necessarily a good thing.

Not just the engine, the entire car is BMW, built in their factories and everything. Having owned three Supras, and have driven the BMW one, I can honestly say that I'm disappointed.

nope.

Canadian parts giant Magna International will assemble the 2020 Toyota GR Supra at a factory in Europe.

Subsidiary Magna Steyr will build the sports car for Toyota at a plant in Graz, Austria.

Engine used is the 2GR-FE engine which is port injection only, while Toyota also has the 2GR-FSE and 2GR-FKS which are port and direct injection. The DI family of engines was never configured for a transverse mounting.

A number of posts on here about catch cans, stock dual can (twin banks) Radium vs my single bank setups, fwd on S's and aft on 4xx's as Lotus relocated the PCV on the 4xx's based on oiling on track days.

Before even considering installing CC's determine if your car and driving habits need them. Easy check, pull vent hoses at SC house and intake tube, insert paper towels and see if any oil trace even exists.

Well this discussion has been addressed in many forums. For port injection systems I still think a catch can is needed if forced induction is used. No real cost and benefits are proven. Now in direct injection just go to the bmw, Ford Focus ST, or Mazda ms3 forums. In my focus st it had build up at 1000 miles. Installed Moroso catch can and 59000 miles later no black residue but there is some soot which is easily removed with the crc intake valve cleaner. This should not be sprayed into the intake track with a forced induction car but rather remove intake manifold and clean with each respective valve bank closed. This has made a great impact in my focus for idle, fuel mileage, and low end torque. For our cars with port injection a bottle of redline si1 before oil change is quite sufficient. Tommy

But again, no need to add something if your particular car is not needing it and it's easy to measure a need before acting. Complex, no, troublesome in an already tight engine bay yes, added maintenance yes.

Do I have one? Yes, on high speed tracks under full throttle on multiple segments I have oil to pour out at the end of the day. Cross country road driving at healthy speeds and in mountains, none.

But if anyone wants a Radium catch can (single) with dual bracket and hoses, I have brand new available; I only used a single can.

You owners might want to look up Top Tier gasoline.

You're correct about the FSE, but the FKS is used in the 18MY+ Sienna, Highlander, and Camry, then the 19+MY Avalon, ES350, and RX350. Which are all transverse mounted.

I stand corrected, still doesn't change the fact that it's a badge engineered car.

I stand corrected on the new FKS as I had not read up on it. The FKS is too new to be sold to Lotus and would be deadly to our tuning desires as the exhaust manifold and cats are cast integral into the heads. Goes back to Europa days where you couldn't change carbs because manifold and head was the same casting.

Although it limits the possibilities of gaining power from adding long tube headers, there would be power left on the table if they used Toyota's restrictive down pipes. Most of the power gain from FE --> FKS is due to revised cams, DI, and cam timing. The exhaust ports look like they'd be happy to accept a pair of turbos tho.

Why try to make things tough, you can take the current 2GR-FE past 311 Hp in NA form and of course with the SC's we are only held back by lack of manual transmissions. BOE can tune your cam timing how you like right now.

60 track days, 1x yr cleaning of MAF and intake which, of course needs some attention. Never burns a drop of oil. Was going to consider catch cans but don't see any benefit.
