I have my own copy of the technical data sheet, exactly from "Hyundai Technical training team". I was reading along and this what it said... So basically NA-T conversion!!:yikes:

"The use of generic parts in the FF NA engines has been maximized, and it was designed to be compatible with components from both FR MPI engines and TCI engines using the DUAL-CVVT, cylinder block, and timing chains etc."

If I'm reading this correctly, some parts from the SRT & EVO engines maybe interchangeable?

Hey just a obsevation but can we make sure the pics are just small enough that they don't break the site layout. If they are to big they push the table that they are in to the right and makes it not align with the rest of the layout.

^ Sure, sorry about that. But yea I was thinking the same thing that the caliber srt4 engine internals may be interchangeable. This will be the fastest way to stroke the motor, take the srt4 caliber internals and put them in the 2.0.

This is basically the same as the Technical docs we have on the site right?. Keep in mind that the internals of the engine have to be different for forced induction. The NA 2.0 engine is at a 10.5:1 compression ratio and the 2.0T is at 9.4:1. So at the minimum the pistons and/or rods are different. The tech docs also mention the Cyl head is reworked. I'm think when they say "generic parts" they are talking about certain sensors (crank, cam, temp, oil, etc) or valvetrain components (springs, seals, etc).

Actually after further examination it does say the rods, piston pin, piston rings are modified. Also look at the weight difference between the 2.0 NA and the turbo engine. The turbo engine weighs about 15.7kg (34.54 lbs) MORE. Some of that is probably coming from the turbocharger but the rest I'm hoping is coming from forged internals!

^ Yes, it is in the technical data sheet on the forum:rofl:. I believe that the crankshaft is forged. But that is all i no. I will definitely will do some research.

Well the stock rods look pretty beefy, almost like what you'd see in the EVO, maybe even beefier. I'd be a little worried if the pistons where cast. No one has really answered these questions yet. The waiting continues...

The internals are diffrent and look different. I wouldnt go as far as saying its a NA-T. The Mazdaspeed Protoge was a NA-T where they just took the stock motor and put a turbo on it with no internal changes. The Hyundai motor has the needed changed to make it turbo friendly.

Well, I think this is like 50/50. In the video and the tech sheets they were mentioning a lot of n/a material. I think they did this because did this to save money, maybe the internals are slightly beefier, but not much. With the statement "Use of generic parts has been maximized", seems to me that they made them a little bit stronger. Yea they made turbo diesel engines before, but those aren't going to be modified. As a car manufacturer how far does maximized means. And you look at the tuners perspective. What we think as maximized doesn't mean the same for the Hyundai.Maybe maximized means just enough to withstand the turbo pressure, and all of its components. I do not like the word "GENERIC". It means to me that they are using cheap parts. But after re-reading the "generic" portion I think they were mentioning the n/a parts as being "GENERIC". But hopefully Hyundai did their homework. So far, so good. IMO.

Generic parts seems to mean general use parts, parts used in a multitude of applications, i.e sensors. Maximized seems to mean used frequently to reduce costs of production. My opinion only.

The pistons and rods have changed and thats all I really care about. I understand reusing some sensors as long as they interchange its not a big problem. It does say the head is diffrent (combustion chambers) but uses the same cvvt system. It doesnt say anything about using different cam specs. Block is the same since it looks like they didnt go with 4 bolt mains like on the 4B11T.

Yea if you look into the technical sheets it goes into slight detail of what is actually a carry over from the n/a engine. It's just modified slightly. I really do think this is a s n/a engine with enhanced internals and a turbo on it. And as far as the engine that they are basing it on is the sonata 2.4 engine. I have the spec sheet and in fact that this is "the 2.4 DOHC MPI" that they are mentioning..

Its no big deal or suprise. Nissan has done it, so has Toyota. The NA SR20 is the same as the DET except for the internals and a few other pieces. 90% of the sensors carry over. This is the same thing thats happening here.

Good discussion guys. According to the Theta Engine Features that Genesis2.0t posted the turbo engine does in fact have different or modified piston, rods, valves, and head. That's good news as it means Hyundai did make some changes, most likely in stronger parts that will withstand the increased power. Also I agree that the fact that it may share parts with the NA engines is no biggy. Like Kevin mentioned other manufactures have done it. I mean its based off of the World engine afterall. Ford did the same thing too with the 2.3l OHC turbocharged Mustang SVO's, Turbocoupes and Merkur's. Same engine as the NA engines except it had different pistons and heads (forged pistons and lower compression). Everything else was basically the same.

I forgot about the 2.3. Those engine sure could take a beating and keep right on going.
