Theta info:

[SPIKE]

http://story.news.yahoo.com/news?tmp...sler_engine_dc

Okay the THETA is being built, I heard of the engine about a year ago in Korea when I was there, and I have been hearing a lot of the BS rumors on the message boards since then.

The Theta is being built by 3 companies, but will they all be built the same? ie: boost? hmm probably not (due to mitsu using the engine in the Evo and using turbo options)

Will Hyundai turbo a factory car again?..hmm probably not due to the fact that Hyundai had the worst rep when they had a boosted car in the line up

Also people on RD Tib (should be RC tib) keep wanting to talk about a swap etc...and swapping with the GK 6-spd (when the tib has a 6 spd option in Korea for the beta but not here) and other outlandish talks of swapping in the theta into an older tib etc. If that were the case anything is possible with $$. Would it be beneficial probably not


I am not 100% sure on a lot of the specs of what Hyundai will be using yet, I will find out more.

Feel free to comment.:

i was interested until the very last sentance: ALUMINUM BLOCK gre:

while it does make sense for them from a manufacture standpoint, i want a stronger block damnit. im sure mitsubishi will be pushing and testing the envelope in the EVO though, maybe we will find out it is a strong little sucker. with a 300k service life maybe it just will be...

from what im hearing they will be an option in some 2005 vehicles? any idea on that?

Look likes a solid motor, but since the delta is an aluminum block and the rumors about it havn't stopped what are the chances the theta will be accepted by the tuners?

[SPIKE]

I have heard that Mitsu will be using the Theta in the Evo X (heard) but I am not sure

now let all the hybrid lets swap people ask about putting it in a tib...or something else ....

One of the main points to emerge concerning the new Theta [4 & Lambda V6 Hyundai-designed engine ranges, is that the agreement by which the engines are also being licence- built by Daimler-Chrysler & Mitsubishi specifically states that Hyundai will be solely in charge of all development work on these engines!.

There is some further info. on this subject contained in another post I made yesterday :-

QUOTE

The Sigma`s block is iron Beppo!.

An all-new Lambda V6 motor (all alloy, timing chain & 300K design life before stripdown service) is currently being readied in several capacities by Hyundai......to eventually replace the Sigma and Delta.

This, together with the similarly-constructed [4 Theta motor, is the subject of the licencing deal with Daimler-Chrysler & Mitsubishi........which is expected to earn Hyundai around U.S.$50 million annually!.

@ Beppo.........some specs. from Korea :-

2.0L Theta
In-line 4 All aluminum block & head. DOHC with variable valve control(VVT)
144hp/5800
19.4kg-m(140lb-ft)/4000
Won't be available in US

2.4L Theta
In-line 4 All aluminum block & head. DOHC with variable valve control(VVT)
166hp/5800
23.0kg-m(166lb-ft)/4000

3.3L Lambda
V-6 All aluminum block & head. DOHC
230hp/5800
31.0kg-m(224lb-ft)/4000
Will be put on New Sonata and Grandeuer (Code name TG; XG for US market)

3.8L Lambda
V-6 All aluminum block & head. DOHC
Max power said to be around 260hp.

The numbers are Korean spec. US & EU numbers might vary.

Looks good :smoking:

[tranceokido]

Lambada...that just sounds good. I can't wait for Hyundai to put this into their Sonata, XG, and Tiburon. Hell..just put the 3.8 in all of the cars. Sounds good to me!!!!:lol:

Just because Hyundai had a bad rep back in the days when they had a turboed car has absolutely nothing to do with if they will ever turbo a car again.

Also, as far as not being accepted because it is an aluminum block is crap.
350z = Aluminum alloy block
SpecV = Aluminum alloy block
SRT-4 = Aluminum alloy block
Civic Si = Aluminum alloy block

And the SR20 which is probably the most widely accepted 4cyl motor in the world for tuning uses an Aluminum alloy block.

So, I ask you guys, do you realy think tuners won't accept an Aluminum alloy block?

[beppomarx]

oh i am not saying that an aluminum block is completely inadequite. i know the likes or porsche and maserati make well over 100bhp/liter with aluminum blocks. its the fact that its a hyundai designed aluminum block that was not meant to hold extreme modifications that bugs me. even in an iron block small imperfections like main bolts not being long enough or conservative stress testing procedures will be less of an issue due to sheer material strength.

350, SR20, all the motors you listed were built specifically to withstand abuse because when they market the vehicles that they will be used in, theyre performance oriented and overengineer them to some extent so that although they are not going to warranty or guarantee anything, their compact/midsize performance and aftermarket status wont be the laughing stock of tuner meets.

its because you can probably make a motor with a 300,000 service life that still has low limits or a weak bottom end that still wont hold 300hp because it was designed (possibly) to only hold 170 or 220hp. who is to say hyundai wont target for that and that only?

of course if mitsubishi has a foot in teh door and plans on boosting their share from the factory then of course thast a different story and they will build the basic design around their needs too, bot its not for 100% certain that this will be the new EVO motor. sure it will be the most widely produced block in history but will it be a tuners dream or just a reliable k-car/grocery getters dream because it will last for 4 years without any defects?

neither you or i will know for sure. all i am saying is that i am still skeptical because of what has come about in recent with the delta. im not playing off the motor as junk, i dont make decisions based on partial information. i would have been more reassured right now if i heard iron, but we all will just have to see how this one fares once we get our hands on it. no other way to tell and i have an open mind until proven this way or that.

God I wish I had shares in Hyundai!
