Whats good WHP for drift E30s and E36s?

[protomor]

JW. For a car as light as ours, we don't really need 900whp. But what IS a good number to shoot for?

[mattmartindrift]

what track
what gearing
what tire
what suspension


all play a significant role in "optimal" power goals.

You tell me. Whats good for what settings? I'm speaking in general here not just me specifically. Plus I feel like you should change your suspension/tires/gearing to the power you want to shoot for.

For a beginner, a stock m50 in an e30 or e36 will sustain 2nd gear slides pretty easily.

[JDJordan]

I have a stock 328is with straight pipe exhaust. ha. ktc coils. forgelines and a 3.91 welded diff. works great. 60mph 3rd gear clutch kicks all day around my local track

[tEckniks]

i would say atleast 300rwhp with a lsd with a nice amount of lock, or welded.

theres no way in hell my car can do the long bends without kansei drifting.. which i would probably die

No way dude. Trust me... stock m52 is perfect. My interior is stripped but whatevs. You just need speed and thats were the 3.91 comes into play. Youll get up to speed so quickly. Honestly its a better bang for the buck than m50 mani and m3 cams. serious!

i was thinking about the 3.91, but I DD my car so I would hate my life driving on the highway. 80mph at 4.5k-5k rpm is no fun.

Oh for sure. I lost about 4-5mpg when I installed it. I DD my car as well

[RJ's325ITS]

I think 3.15s and fresh rebuild diff will do it to start with.... once you move to 55+mph open drifts then you will need a stiffer suspension and somewhere around 350wtq.....

With a small turbo I'll move to 2.93 gears (since spool starts at 1500rpms), with a larger turbo I will stay with the 3:15s (spooling the turbo at around 3000rpms).

Running a "thick" rear sway bar will help and springs over the 600lbs are a must.

this very much depends on your experience, or if you want to be competitive.

those things will make an easily driftable car; but, they will also make a slow-drifting car.


most well-prepped cars are actually going the opposite direction: small/no sway bars and soft springs -- think dirt oval sprint car/rally car.


My old SCCA ITS-prepped E30 325is was PERFECT for 3rd gear drifting:

- welded 4.11 (automatic diff, i think it was 4.11ish)
- 120k M20 w/ conforti chip, intake + stahl headers
- ground controls with bilstein HD dampers
- 205/50/15s on panasport magnesium road-race wheels
- kirk bolt-in cage




My S13 was about perfect at its old power levels; which was around 350whp.

- 4.08 rear
- 265/40/18 on a 12" wheel
- KYB dampers with 10k/8k spring setup
- cage
- 2375lbs w/o me and about 1/2 tank of fuel

[Piner]

e36 200whp is comfortable for a beginner, I only have around 230whp and I have a ton of fun with my car.

[protomor]

really? I hear E30 guys would beg for 200whp but the E36 weighs more. I'd think 230whp would be just right.

So bassicly OBD1 S52.

[protomor]

That would make me happy in the pants

[JDJordan]

Maybe some have seen this, but I assume most havent. Here is a link to a local drift guy with an e30 with a ca18det in it. Supposedly enough to have more than enough fun with the light e30.

Some of those pix he has his old M20T. Could have sworn he went M30 tho. Maybe that was Erik

CA18 makes 160hp and has a garbage transmission...worst engine choice ever. For maybe $500-1000 more they could have done a 1jz w/ 280hp (in stock form) and never worried about transmission failure.

Yeah if you read through the thread so many people told him not to do it but he had his mind set on it and I think he got pretty hooked up with everything. His main concern was weight... I guess 1j weighs a lot more the the 1.8l ca... IDK whatever... just thought people may be interested in the car

I have a CA in my s13 coupe for about the last 5 years...great motor if you give it chance and show it some love. in stock form ill admit, yes it is kind of lack luster. But put 300ish to the ground and it being so rev happy itll slide just fine. There is a few running in around here in the Ohio, indy area.

Ca's are temperamental but def not garbage...i haven't had any or know anyone with transmission issues to date..knock on wood.

so, for a couple hundred dollars more you could start with near 300hp in stock form + more torque + same durability, except with a 300hp CA, you start killing transmissions with any type of real tires or clutch. Not to mention, the E30 came with a straight 6 and is easily setup to run that.

Then, with the 1jz if you wanted to upgrade the turbo(s) like you HAVE to with the CA, you're easily at 400+ hp that's more than reliable.

yeah, I was one of those people advising him against it in his thread on Ziptied.com



But, like I just stated, the E30 came with an iron straight 6 and do plenty well with them.

[JDJordan]

I probably would have gone with a 13b over any of the options haha

most well-prepped cars are actually going the opposite direction: small/no sway bars and soft springs -- think dirt oval sprint car/rally car.

As any other motorsport the power comes with the territory, the better you become the bigger dog you pick to play with thus needing more power to play with the big guys..

An easy to drift car will get you anyone started, and on the right path; but sooner or later everyone comes to the same conclusion "I need more power".

Rally and oval racing might share some of the techniques of drifting, but they are so far from each other. In one had we has a suspension set up with more travel that a stock car, and in the other we have cars engineer (If I can say that) for left turns only and off set chassis.

From someone that has done rally I can tell you that all they have in common is counter steering to compensate over steer, and throttle modulation to steer the vehicle.



My old SCCA ITS-prepped E30 325is was PERFECT for 3rd gear drifting:

- welded 4.11 (automatic diff, i think it was 4.11ish)
- 120k M20 w/ conforti chip, intake + stahl headers
- ground controls with bilstein HD dampers
- 205/50/15s on panasport magnesium road-race wheels
- kirk bolt-in cage


So you campaign a E30 with a welded diff? The most aggressive set-up I've seen on a race car is 50% lock-up at accel and 40% at deccel; NEVER a 100% lock up.

for your set-up I can tell you like a very lose car for the road course I can understand if you nissan will be on the lose side too... BTW how do you guys rate those suspensions?

10,000 Kilograms (22,046 lbs) for the front doesn't make any sense to me.... or is it 10K pounds? I don't get it, I'm used to rating suspensions in Newtons and pounds.

10k x 56 = 560 lb springs (in/lbs)




or


8k springs:

8 x 56 = 448 lb.

[The Fello]

in my e36 i use 2 make around 350whp and it was more then enuf power for 3rd gear clutch kicks & leave huge clouds of smoke , i did run a 3.91 welded with 1000lb springs all around.
for drift tires i normally ran 225/50/16s on stock 16x7s

^ damn, could have been running alot more grip on the rear then, I run brand new federal SS595's 225/40/17's with 120 less whp. With 350rwhp and more grip you could really haul some ass around the turns.

The E30 was not setup by me, nor campaigned by me in the Mid-Atlantic SCCA series (MARRS) -- I purchased it from a friend and former employer. He is a bit of a maniac on course, and i'm still not sure why he went with the welded diff. As you stated, I think he liked the joy of battling mid-pack and doing a lot of sliding more than being up front.

Many of the Japanese "coilover" producers rate their springs in kg/mm which has been abreviated to kg, then just "K". So, it has sort of been adopted as "K", now. 1kg/mm = 55.997lb/in

you are right, i just like the feeling that i m on ice wile drifting. at OSW i can enter the high bank at 70+mph in 4th , & at the local CFRC its 3rd gear 50-60 mph enters then ice skating from there on... :buttrock

[Piner]

Man I knew that oval looked familiar, yeah I when I'd try to slide the bank there I wished I had about another 100 whp
