car held together like a freakin champ. opened my tool box twice. once to remove silencers and once to put them back in!

times were not as great as i thought though. a lot of pretty stock cars were taking it too me. working on driving skill mainly, and getting rid of worn tires will also help immensly(huge flat spots, 4 track days).

glad to know your putting that motor to good use. Very impressive. Keep in mind your pulling extra weight with that block in the car. Was every one else using 4cyls? What stock cars were running up on you?

just to name a few... e36/e46 m3s, 350zs (both nismo and track editions), the most discouraging was probably a most likely 4000 lb+ 2002 maserati spyder that looked totally stock slowly walking away from us on a long, sweeping, high speed turn. so no, not necessarily light cars. my car ended up pretty close to the bottom. my azenis had already seen 4 track days prior so they were basically worn down. combined with the greasiness from the heat (90 deg day + sunny) i would feel the car constantly tracking out and undering a bit. throttle steering worked to point the car, but the whole car would kind of just slide to the outside. also we had to be VERY careful as the power was pretty explosive coming in to boost = throttle oversteer + spin out possible at any time.

i have newfound respect for OEM handling cars now. the track we were at is definitely suited for lighter cars, but the cars i mentioned above were probably at least my weight or heavier. tires were a big factor, along with driver skill. granted i had a passenger the whole day (we both weigh a bit over 200lbs each.) in the end, seat time is really the key, and that is tough to keep up with a modified car that is known to produce heat issues. tougher to focus on just driving when you constantly worry about temps, tune, etc. etc. just to be conservative, we were pulling the car in early during all sessions. basically when i saw temps get over 210F water and oil over 240F, i'd try to chill on the car a bit. we werent competitive so it wasnt worth risking anything. i had done a lot of work to the car up to the day before, so nothing had been quite "proven" yet.

What about on the straights? You should have destroyed them in straight line power.

I'd have to say a 350-400 hp 240 would be the best case for a circuit car with proper brakes, suspension, tires. I know at a bit under 300 when I tracked mine with stock turbo I had to be very careful with my corner exit while getting onto the throttle. Better tires would have helped this greatly.

Hope you had fun at least!

the car was owning on the straights. a lot of ppl were coming up and checking out the car. i was probably one of the fastest "straight line" cars there not including the shop race cars. there was an FD with a t78 @ 500hp there. everyone complained about him blocking in turns, then pulling away on the straights and not letting people by. he was lined up behind me a few times, probably thought he would eat me up on the straights. he was in for a surprise.. we walked away from him

corner exit speed was a problem, and also the track doesn't have many clean straights. for example, one of the straights has somewhat of a "jump" in it that you need to be very careful on.

i never posted it. the car's got tein flex coilovers, nismo power brace, SPL TC rods, cusco strut tower brace, stock sway bars with ES bushings, full new rear subframe bushings, tomei 2-way diff. the setup is very basic and am not going to blame it as of yet.

actually i dunno if i mentioned before but my rt615s had 4 huge flat spots on them from doing a bad braking lockup. thud thud thud up until about 40mph. so i think that really caused a lot of high speed instability (front end lightness, car skating all over, etc.). really made the car feel a lot more out of control than it could've been had it had some fresh rubber

and no ABS. the car is really stressful to drive, as my cousin puts it who owns an STI. i consider him a decently experienced driver and he said its tough. no abs, rear end lockup under braking, steering wheel lightness up front under hard accel, power oversteer if rpms are up, spinning tires on the straights, uber turbo lag if rpms arent up, you name it. in the end, my car (at least the way it was on sunday) falls short to lightly modded 350zs, m3s, and s2ks on this particular road course.

I love track racing. Running an RB powered car myself, high temp brake pads, and tires are the biggest key to running a 240.

What are your alignment specs?When it comes to 240's you want the most positive caster you can possibly have. I ended up getting mine to around 6.2 degrees positive. Camber and Toe also make a difference.

I will tell you one thing.... Dont waste your money using high performance street tires.... Get slicks. Its worth every penny and you'll be amazed at the difference it makes. I've used AVONs, and Hoosier A6's. I think ill be trying out the new R888's soon.

There is another 240sx out at our local track that has 300zx brakes, 4 point cage with a hoop, i/h/e and slicks on his 5 lug rims that are 10 in the back and 9 up front and he runs faster than the majority of the cars out there with double the power he makes.

Also, if you still have a windshield washer reservoir or a system to hook it up, get it full of acetone and hook up nozels to spray on the FMIC and Radiator if you have one thats aluminum. It works great.

no in car vids, sorry.

i agree on the caster thing. i think i'm running 5.5-6 right now. i'll see if i can raise it more

I hear you on the tires. the rt615s were just super greasy for me, and the flat spots i think were just skipping me around the track. i started looking at the other street tires, dunlop z1's, re01r's, etc. but i think i'm gonna go with the r888s next.

i'm probably not going to do the spray cooling. i need to work on ducting my oil cooler, and cutting out a hole for a cold air intake. right now my air filter is sitting right behind the radiator, and my ps resoivoir is sitting right next it too. probably gonna cut a decent hole behind my dr side headlight and run without it when i'm on track.
