hello everyone.
im new to this site and i would like to say im excited to be apart of it and i cant wait to hear the input. anyways.......i have been doing a lot of research and i may be out of the loop or not, IDK. the 2001 hyundai tiburon RD2 engine is real hard to find performance parts for. what i have found out so far has been the 2005 kia spectra has the same engine(i believe, which i am waiting confirmation from NFXperformance.ca) if that is so that will open up engine mods for us RD2 fans. i guess my question would be does anyone know of any other makes and models with the same engine so we can continue to upgrade our performance of our TIBS. later and cant wait to hear from you all. peace

 

The 05 (and any other year for that matter) Spectra does not have the same engine as your Tiburon. You have a Beta I. The Spectras have the Beta II. You share an engine with the 97-2001 RD and RD2 Tiburon and 96-2000 J2 Elantra.

The Beta II is as you can probably imagine pretty similar to your engine, but most parts do not interchange.

 

just curious, can do you what the differences are between the betaI and betaII? would an engine swap work? just curious once again.....trying to keep my performance options open. after i posted this i found out about the elantra......hard to find parts for that to.

 

Straight from Wikipedia, so questionable accuracy but all sounds correct. Possibly other differences also.

<div class='quotetop'>QUOTE</div><div class='quotemain'>During 2001-2002, the new Beta II engine made its debut in models such as the XD Elantra and GK Tiburon. Output is 138 hp (102 kW) at 6000 rpm with 136 foot-pounds force (184 N·m) of torque (184 N·m) at 4500 rpm. It has a cast iron engine block and aluminum DOHC cylinder heads. The latest version of the 2.0L Beta engine (G4GC) features CVVT, which only in intake side, a first for Hyundai/Kia. The following changes were noted.

<ul>[*]Redesigned block with external contouring of cylinder bores (ilo flat sides), extra ribbing & one extra transaxle fixing point (now 5)(less NVH)[*]Crankshaft now has 8 counterweights ilo 4.(NVH)[*]Cast & ribbed aluminium sump pan (ilo pressed steel sheet) with stronger joint to transaxle (NVH)[*]Reshaped combustion chambers, ports & pistons (performance, [fuel] economy, emissions)[*]20 mm longer intake rams, 8% smaller surge tank, resonator added, spark timing & valve lift optimized, lighter valve springs, denser conrod bearings, returnless fuel system (ilo return type) with higher fuel pressure & smaller injectors (torque spread & econ)[*]Cylinder head machined to more precise tolerances[*]Head gasket now 2-layer (ilo 3)[*]Idle speed reduced to 700 rpm from 800 rpm (NVH)[*]Hydraulic engine mounts (4) ilo rubber (NVH)[*]Heat shield installed between engine & air filter, reducing heating of induction air (+2% output).[*]New camcover with I-piece high-specific gravity polypropylene baffle (ilo 2-piece pp)[*]Oil flow reduced (econ)[*]Mechanical valve lash adjusters (solid lifters) replace hydraulic, improving valve clearance precision (durability).[*]Lower valve spring load reduces valve train friction (perf).[*]Engine cover installed (NVH & dress up engine bay)[*]Catalytic converter now upstream adjoining exhaust manifold (ilo under car) (emissions)[*]Other detail changes to: alternator, intake manifold brace, power steering & a/c pulleys, idle speed actuator, oil filler cap & drive plate between engine & torque converter[/list]</div>

 

Also switched to MAP (from MAF) on some of the Beta II engines.

 

you can swap the beta 2 into an rd. Optimoprime did it (it's just like beta swapping an accent) except you won't have to modify any mounts. just swapping sensors and extending wires.

 

not true my man. The beta II engine will not go into an RD without modification to the harnesses. The CVVT functions are not encorperated into the ECU and the sensors are redesigned. It would take a bit of rewiring.

However, the Beta 1.5, the 2002 Elantra I4 engine has no CVVT and uses the same sensors. The beta 1.5 upgrade is the best.

 

What the F*CK are you talking about?? There is no beta 1.5????
If you want to get technical a BETA II from and o1-o3 elantra or an o3 tib (ALL MAP BASED ENGINES) can be swapped into an Rd with little effort. The betas with CVVT are still the exact same engine Just with the cvvt solenoid near the coils.

 

well. you all are still saying its possible. but i think im just gonna keep the original engine due to being more rare for parts. i like the challenge of finding the parts and power im looking for. gives me something to do. thanks for ya help. i will post my tibs pics when i get home in a week or 2.

 

What parts are you looking for exactly? Pretty much any and all N/A mod available for any other car, is available for Tibs. Plus, theres supercharger kits and a ton of turbo kits available too. There may not be as many companies that produce parts for Tibs, like there are for Civics...but you can definitely get any performance part you want or need for your car. smile.gif
