Hi Guys,

Need some help.

Am converting my EP3 to race in the Supercar Series against the other GT3 Porsche cup cars, a bit like David against Goliath I guess......

Anybody that knows something about the below questions, or have additional ideas please reply:

I saw a widebody kit on an EP3 on the web...go to Google, look at images, and type in Widebody EP3, and then you will get a number of picture, of which one is a black EP3 which looks like its on a landing strip, and you can see the rear and a little of the side, and it says Skunk2 but apparently they dont have this.....does anybody know where I can get this kit from....(I also tried at JAS Motorsport in Italy, but they no longer have any widebody kits)....... ?

What is biggest size rims that can fit on the car 17 x 8, 17 x 8.5, 17 x 9, 17 x 9.5, 17 x 10 provided that the offset is correct of course.....?

I know there is a stroker kit for the K20A JDM Type R engine, but is there also one for the K24 JDM Type R engine....? so I could say increase it to 2700 cc or some where around there....?

I have seem several Individual Thottle body's but they are around 54 and 56 mm, is this the biggest size of individual 4 cylinder sliding type throttle body's and which is the best in your opinion.....?

Reason for not putting a turbo on is then I will be up against the 4 wheel driven Evo's and Impreza's and then I think I am ****ed for sure.....?

What is the highest RPM that I get get out of a K24 JDM Type R engine with a stroker kit.....I am using a Motec M800 by the way......?

I have recently installed a Wavetrack LSD, but have not tested it and therefore have not idea if its better then my old OBX......?

I am using cam's from Jeremy at Drag cartel which is Stage 4.....

My suspension is a Full race spec KW suspension with 3-way adjustment in the front with both helper and tender springs, and with a 2-way in the rear, also with tender and helper springs, same as is used in the BTCC (British Touring Car Championship).

My brakes are 345 mm discs x 30 mm from Project Mu in Japan, with 8 brake Pots and 280 mm in the rear, and I have full adjustable brake bias.....

I am getting a sequential gearbox from Hewland.....

Any other ideas on what I can do (Not including superchargers and Turbo's as these are not allowed in my class as this is N/A engines (Non aspirated engines)......?

Look forward to hear from you guys.

 

research before they start comin

 

oh god... you are trying to go up against a rwd 450+ hp with a 4cyl wow... you should really relook your goals...

 

CRSX sells a stroker kit for the 2.4l.


good luck with all this....

 

I would tend to agree, how ever looking at this, I think there is a slight chance.

I am curently on 15" rims, with 195/50 slicks which is Michelin S9B's, and I use a K20A
Type R engine, with 236 WHP, and my brakes are 300mm x 24 mm, by throttle body is a single 72 mm BDL body. I am using a 2-way Tein Super racing suspension, which is okay, but nowhere near the best or a KW suspension.

My best lap time is 1.07.6.

The fastest GT3 Porsche is doing 1.04.8

This means I have to find minimum 2.8 seconds per lap.

I can now change from a K20A to a K24 with a Crower stroker kit (Just found on the web a min ago).....making it a 2.6 Ltr car, and I can change from single throttle body to a direct injected individual throttle body.

I can change the size of the brakes to what is mentioned above, because I put bigger rims, and tires on, and the Michelin S8B's are about 1 second faster per lap, at least......

I know its a long shot and a guess, but I would think that with 600 cc more, and more torque, plus about 60 WHP more, and the bigger and wider tires, and bigger brakes, I would be able to find 2.8 seconds in a lap....

I am how ever very new at this rebuild as nobody here has done this before, and there is nobody I can turn to for help.....

ok... with your 15 you wouldn't be able to even have the type-r brake setup because they wouldn't fit (type-r is a 12.1" disc up front)

Also running 195-50-15 on an EP3 and its a race car... you should be running at least 225 on 17 and that is minimum...

Also the Porsche is a better balanced car then the civic...

Btw gaining 2.8 secs a lap is huge when it comes to racing... I don't even see you coming close to it!

Your goals are not realistic!!!!

 

Hi Dave,

You critics well noted.

I live and race in Thailand (I am a Danish National).

Rules here specify that we in Super 2000 are not allowed to use bigger wheels than 15", and putting them on a car which is designed for 17", already starts giving you problems.

Sure you are not able to read Thai, but look at the below link:

At the top you will see it says 2000, which is the class called Super 2000.

At Point 9.1 you will see it says 15".....that is the place where it says we are not allowed to use other size that 15" rims

At Point 9.5 you will see it says BF goodrich, this was later changed to Michelin S9B, but since they are made in the same factory by the same company, they wanted to promote the BF goodrich tire, so they took the Michelin S9B tire, and labled it BF Goodrich, just for our races, no where else in the world.

You could also have a look at our race teams web-site: www.stuvik.com/Thomas.html

Here you can see many picture of the car, and in some pictures it more easy than in others to see the 15" rims on the car.

Rims are 15" Project D from Lenso, as these are the only ones, that will allow me to use a
300 mm disc and the 4 pot calipers.

Would appriciate you telling me what I can do, and where I can get the parts, to at least give it a try, and not claiming what I can not do, and what does not fit on my car.

You might very well be 100% correct, but the only why to find out, is to try, I would say.

1st step will be with old configuration, with the exception of the 17" rims, with a +10 offset, and 245/35/17 slick S8B tires, which should be 1 second faster, and if its not, then we are closer to you being right, and if it is, there is still a glimmer of hope.

I can borrow a set from a friend, so that wll be a no extra cost, except for the practice fees....

Do you have any idea where I can get any of the parts I am looking for.....?

 

DaveSi677,

You car looks nice, did you get it sold yet....?

DaveSi677,

By the way the Porsche 996 GT3 Cup car from 1998 comes with around 320 Hp....

Its undoubtly faster than a Civic in the straights, and on long sweeping tracks a Civic would not stand a change but maybe a little on smaller shorter and twistier tracks.....

BR

Thomas

 

Ok first off which car are you taking about? The EG or the EP3... because if its the EP3 then no my car doesn't look nice at all... but the EG well ya that car was sick!!! It was built for one thing and one thing only racing!

Ok with the 17 you will probably drop some time over a single lap... that will help alot!

I know that Type-S'paz mentioned that Club RSX sells a stroker kit for the 2.4L but apart from that I haven't really hearded or researched anything... tell you what give me a tomorrow to look and ask some of my friends and ill post something up for you!

 

Hi DaveSi677,

I was talking about the Black EP3, that was listed on a web-site with pictures....I thought it looked nice....(Okay not a race car, abd in very good nick, and looked nice.....

Looking forward to hear from you, if any of your friends have any input to what can be done.

I was surfing the web-last night and found a lot of interesting things including a Mental
1000 WHP EP3, called the H-badge Monster......Link is:

http://www.turbomagazine.com/feature...e_r/index.html

I found that Quarter Master clutches makes a 5.5" Race clutch....

I found that Brian Crower sells a stroker kit to convert a K24- into a 2.6 Ltr engine

I found the ITB makes a Indiviadual throttle body of 54 mm with direct injection

I am in doubt if the K20A with a stroker kit making it into a 2.3 Ltr is more or less powerfull than a K24 with a stroker kit making it into a 2.6 Ltr model....

Would think that the K20A with a stoker kit could take higher revs...?

Any ideas anybody....

Anybody knows where to buy the widebody kit for the car....?

 

I am guessing that you are refering to this widebody EP3



If you are looking for the BC Stroker kit there are many places that you can pick up a set. ClubRSX for example like you meantioned sells them. But it would be much easier for you to just throw on a supercharger running about 7-9psi and have about 275-285whp and the car will be much faster and much cheaper to build.

Don't bother listening to all these haters that are talking **** to you. I have to give props to someone who actually tracks their car instead of just having it as a trailer queen.

 

i would do a k24/K20 frank with a supercharger running 8-9 psi with a light build on the motor if you want to hang with some GT3's on the track.
just my .02

 

post in the road race forum, you'll get alot more help

 

My sister said that she never thought I'd make it through Marine Corps boot camp. When I graduated she said I wouldn't live through Iraq, now I'm posting on Honda-Tech, someone was wrong. Let your progress speak for its-self man. You can do it if you set your mind to it, ignore negativity.

Wilwood Big Brakes and blue brake fluid and you're good. You also might want to think about fabbing a S2000 oil pump on the right side of the K block. In hard left turns the 3 and 4 cylinders can run dry from lack of oil. Plus look into getting a laser edged S2000 crank that will increase (in small part) your torque out put. Believe me, you'll need everything you can get in order to win. But the S2000 fabbed oil spitter is very possible and so is the crank.

Let me know how everything turns out.

No one thought a EP3 with a supercharger could beat a 240 turbo at Willow Springs and it happened, its all on you man.

Good luck.

 

Give you a little info on this kit. That is a Tracy's Sports kit that only Skunk2 was able to find. In order to have them make another i think you're looking at spending roughly $10k.... It's not a cheap kit. Which comes even worse news for you. Skunk2 sold that kit for a little under $1000.

So you missed your chance on this one. Look into a BTCC kit if you can get your hands on one. There is some company in the UK that is producing replicas. Otherwise 5-Axis came out with a specialty widebody kit for the Sparco Ep3. But you're looking at $3000 for that new.

Good luck, i am an avid track enthusiast and race my Ep3 often. However i believe your ambitions for the car have overstepped it's limitations. I highly doubt that your EP could possibly keep up with an experienced driver in a Porsche GT3.

The reason i say you're overlooking the car's limitations is pretty simple. First and foremost the EP3 is an FF. Which may seem like it doesn't make sense, however it does. The GT Class races in Speed World Challenge usually around 30 laps or so. In that time you'll have already cooked the front tires right off the car. While the Porsche will still have tons of life due to it's weight distribution.

You'd have a far greater chance in competing in a Touring Car class than in a GT class.

 

Also if you're looking for a good tire setup, your best bet is to run at bare minimum a 16x8 wheel. Enkei actually produces the RPF1 in 16x8 4x100. With these you're able to run a 245/45/16 race tire if you're willing to cut the fenders for space. Also you'll need a super stiff spring rate to run these tires.

BTCC Ep3's used 17x8.5 and 17x9 if i remember correctly, maybe a 17x10. Tire sizes i think were 255/40/17 or something in that area.

I personally love 16's with r-comps on them. Right now i am running a 16x7.5 Kosei K1 with 225/50/16 Kumho V710 (front) and used Toyo RA1 (rear). The setup seems to work, however i'll probably step up to some fender rolling and wider tires. I have been looking into running 245/45/16's however as it stands i don't have the clearance for them. I test fitted one to see if it was at all possible.

A 15" wheel will give too much flex in the sidewall, also limiting you to the stock brakes. I am currently running the Wilwood 12.1" kit in the front and stock in the rear. I don't seem to be having any issues with front brake bias.

 

Thanks for bring back a 4 month old thread back to life!

 

LOL! I just scrolled down to the bottom of the page didn't even see that it was 4 months old. Looks like no one has been in the section like they used to.

 

there is no such thing as a k24 jdm type r engine. the newer type-r/euro-r engines are all k20.

 

Accord Type-R engine is a K24!
