Hello,

After doing a lot resarch I came to this site and I would like to post few questions in hope of few good answers so here it goes.

After a few years of hiatus I would like to come back to rally racing ( used to race a galant vr4) , since rally become so expansive I would like to do it a little bit cheaper this time, something like 1600 cc (group 2 in USA) comes to mind as other classes are out of the reach without a major sponsor.

Here are my toughts

06-07 Accent rally car

What would be the best engine ( engine swap) to stay NA and get around 175 whp? (got to be better then SVT, and no turbos are allowed in this class) cc up to 2000
What modifications are required/available to get to this power level??? (intake, cams, header, porting, engine internals)
Drivetrain LSD??? or I'm looking to welded diff, lower gear ratios/final drive swap??? tranny swap, top speed needs to be no more then 100mph but I need to get there quick.

Any advice/help will be appriciated

Thanks

Wish SR was available

are you allowed to supercharge or no f/i at all?

No f/i at all, has to be na.

 

Man...that sucks...well the strongest engine would have to be the 3.5 V6 but doubt that will fit, you could swap the 2.7 Delta but it prolly will throw off your weight transfer..big 600 lb V6...you will easily get 180-190 hp with headers, cams, intake and what not.

 

Well, if I read correctly that you require the displacement to be 2000cc's or less then I would have to say the 2.0l Beta engine from the Elantra and Tiburon is your best bet. The 2009 Sonata's 2.4l Theta is rated at 175hp, but it's a 2.4l engine. The 2.0l Beta engine is rated at 138hp. With I/E you'll get about 125whp. It's around 115whp bone stock.

To get 175whp you will need to do extensive work. Intake, Airram intake manifold, BBTB, header, exhaust, cams, high compression lightweight pistons, head porting, underdrive pulleys, standalone ECU, and even then you might not make 175whp if the head work was less than stellar. The most power I've heard of coming out of a N/A Beta engine (there may be something I haven't heard about making more somewhere) was around 200whp. Those were fully built racing engines.

The Betas make good torque though, so the key (IMO) to making big hp numbers out of the Beta is to free up the breathing in the higher RPM range and spin it faster. If you balanced, blueprinted, and lightened the rotating assembly to the point where you can hit 8500rpm's safely and ensure through cams and headwork that the engine can still breathe at that point you should hit 175whp.

 

Thanks for information, anyone knows/done a beta swap into a 07-08 accent? How difficult it is? How much of a custom work involved?

187 was right on the mark pretty much about the Beta1. You could actually get pretty close to 175 with the mods he mentioned. There has not been an N/A Beta1 that has actually shown a Dyno for 200 whp but some have said they were close or will be after all they complete all the same work

I haven't heard of it being done yet. I'm sure it's been done in Korea and probably Puerto Rico at the very least.

Looking under the hood of the MC Accent (06-08) I noticed that the passenger's side motor mount is of an entirely different design than on previous Accents. It looks really easy to fab up a new mount with the MC's style. There was too much plastic to see what the other mounts looked like to compare to my Accent.

The engine should be able to run off of the Accent's ECU, but that doesn't apply to you because you'll want a full standalone to run an engine like you want to build.
