Genesis Coupe R-Spec

Have we seen any supposed weight figures for this yet?

The stuff it removes seems as though it would save 75 pounds at most. But you get the brake goodies and such for cheaper.

Any chance the motors are underated? ~3300lbs and 210hp doesn't sound all that exciting coming from a ~2700lb E30 with 270hp.

There's no way the 6 cly is underrated, it feels like 260hp at most.

The R-Spec is the turbo 4, so I'm sure upping the boost and decent exhaust/intake should gain alot.

But even GM is getting 260 with the same displacement, and from what I understand the reflash gets another 30hp and 40+ torques!

there are already 2.0T cars pushing 300-350whp right now with turbo/intake/intercooler/exhaust/tuning. 450whp with a built bottom end. Basically, R-spec, add $2500 in aftermarket parts and have 300whp. Seems simple to me, but what do I know?

Hyundai went with DURABLE, RELIABLE and EFFICIENT with the Theta II Turbo. They know there is much more in them, but they wanted to make sure it wasn't some high strung trailer queen. They built it as reliable as the rest of their line up and are allowing us, the car guys, to make it fast.

I will take mine in lime rock green

BobZilla, good point! I've really liked these since they came out and like many I'm REALLY interested in the R-Spec.

It's just the weight that does it for me. I'm guessing your paying attention to some Genesis/Hyundai forums, any word on if 18s clear the Brembos?

I don't know what Hyundai's you've been driving, but the one's I've been driving have been built CHEAP. They've done as little as possible to be able to make the claims or get the look they are going for.

I never thought my Tiburon was cheap feeling. If anything if was a solid car (especially for 1999). But then, Hyundai has always tended to build their flagship coupe's a little better than the bread and butter sedans.

for instance, a co-worker of mine had a 2002 Elantra sedan. Riding in that reminded me of a riding mower with uncomfortible seats, a loud and buzy engine, and lots of vibration.. and my Tib was built on the chassis with the same engine, but did not suffer from that in the least

YO! KIDS!

This thread for is discussing the coolness that is the R-Spec Genesis Coupe. Don't go berkeleying it up with pissing contests about who builds what better.

Stay on track.

Will 18s clear the Brembo's? What HP limit is the stock turbo/injectors showing they are good for?

Yo G, I heard they was reely HAWT!

Burn.

Hyundai claims that 300hp is easily do-able without sacrificing reliability. Keep in mind that although the Genesis's 4cyl and the Evo's mill are very similar the Genesis uses cast bottom end bits, where the Evo's are forged. For serious power (more than 300 hp) without blowing up, bottom end work will be required.

I'm not sure what type of capability the injectors, or turbo have

I liked the 2.0t much more than the V6. I'm really hoping they don't drop the ball with the R-Spec as it seems appealing.

I'd imagine the R-Spec will weigh around 3200 lbs.

So it's been 10 years since you've been in a hyundai? 7 years with my Elantra, durable, nicer interior than the corolla or Civic, more power, good economy and 7 years of me abusing it to with an inch of it;'s life. Auto-x queen for 2 years. Close to 50 drag strip passes. I think it's done just fine. New Sonata is nice. Genesis sedan. New Elantra and Elantra Touring.

I think you should stop with the haterade and be a little more open minded.

Probably had bent wheels.... this gen was suceptible to wheel vibrations and cheap tires. It didn't help that they made the steel wheels out of warm butter. Hyundai has made super soft suspensions for years. they are finally making them track capable and not overly soft. I drove a stock Elantra not long ago and was amazed at how much body motion there was. No wonder I swapped mine out years ago.

From what I've seen, stock injectors can support 275-300hp, stock turbo the same, intercooler supports about 120 and the exhaust about 110. There's a ot of room for improvements over stock.

Okay, can someone clarify for me just what motor is in the GC?

My understanding is that the 4B11T was co-developed between Mitsubishi and Hyundai. It's definitely used in the Evo X, I believe it's also what was used in the SRT-4s. I thought it was used in the KDM GC's, as well, but my understanding is that the USDM GC Turbo 2.0L is not the 4B11T, just really similar to it.

So, how similar? I mean, would a 4B11T bolt up? Do any parts interchange? What are there any key differences between the Hyundai motor and the 4B11, other than FWD/RWD?

Internals and heads are different. The 4B11 is mitsu, Hyundai calls it the Theta II in this version. Without being able to put the two shortblocks together, I have no idea if the bellhousings are different.

The "world engine" was developed between Hyundai, Chrysler and Mitsubishi. They co-developed a similar bottom end, but injection and heads were left up to each individual manufacrtuer. Chrysler made the WE in 1.8, 2.0 and 2.4L N/A versions and the SRT-4 2.4T. Hyundai makes these in 2.4L n/a and the 2.0L turbo. Mitus uses it as the 2.0L T in the Evo. IIRC, the Evo and SRT-4 use forged internals. The Hyundai is not.

Bobzirra, it seems as though you are up on all the Genesis stuff, which has proven to be the best forum for the info?

I'd like to continue doing research on this car, and possbily go test drive one.

I'm going to show off my engineering ignorance here.

What's so complicated in the shortblock that manufacturers would save money to codevelop it? I always thought that the complex and expensive-to-engineer bit would be the head, not the block.

So who are the trusted tuners for these cars?

None? lol I gleen my info from all the hyundai sites and press releases. Like all forums, I take them with a grain of salt. www.gencoupe.com seems to be the most "informative" and seems to be fairly active in developing this car.

Too bad my current brace of Hyundai's won't die or I'd be in the market for one. 166k on the old one ad 114k on the new one and neither are likely to get replaced for another 100k each.

I can not wait until the salvage yards are full of "the other" SRT4s.

Remember people they are talking about Caliber SRT4s not Neon SRT4s.

^ Correct! The Neon/PT Turbo 4 is a completely different beast than the Caliber/EVO/GC.

I would probably still have my tiburon too if an accident had not taken her from me. 137,000 miles on the clock from new (I was the original owner) and still running VERY strong and rattle free when I was forced to choose between broadsiding an inattentive SUV driver or taking the grass.

I took the grass, thinking at most I would rip up some bushes.. I did not know about the drainage ditch in the middle of it
