LOL Thats hella funny bro. I've thought about doing my racing in a safer way. My plan (when my friends get off their asses) is to buy 3 semi-long range radios and 2 stopwatches. Have one friend sit in his car at one edge of the twisties and one friend and the other. I'd line up and at the yell of "Go" both my friends would start their stopwatches. Then if anyone starts coming up the road my friend can radio "Car, stop!" Which should remove the head on collision danger AND remove what little remains of my blind-turn-hesitation. (My friends have decided I'm somewhat psychotic because they're fixated on the "What if" while I'm fixated on the "I can see their headlights on the bushes" but it would be nice to KNOW that nobody is coming. Course the LAST time I went racing with my friends with the intent to prove something (with a video camera ) I was coming to the last turn in the downhill section of this road and I was being a little overconfidant (plus I had the extra weight of my friend in the passenger seat which is EXTREMELY noticable when you've raced a lot. And changes your whole rhythem.) Anyway, I'm taking a hard left turn at about 75mph and I accidentally slid the back out a little too much (yes this is the Stationwagon and its FWD but the back does pull to the outside, its physics) and the edge of my back right tire hit some dirt and the next thing I know the back end has broken completely lose and me and my friend are sliding sideways at about 60mph (we lost some speed from the sliding) facing a barbwire fence (which if we start going foreward, we'll fly off and down a 50 foot deep hill. Not a cliff but we'd roll probably 6 times or so.) Anyway so we slid for a little ways the whole time the back end is jumping up and down as the tires hit rocks and ruts in the dirt and we flip around to complete the 180 at a dead stop. I jumped outta the car to check my rear wheels/axel (which I was sure would be bent and mangled) it was fine! I was shocked. Then I watched my friend in his 91 RS camaro (who was trying to keep up but failing ) come flyin around the turn, slam on his brakes and jump out yelling "What the **** happened!" (as the dust has filled the air) Lol it was great and we got it all on cam. Unfortunately its late and dark and when the 180 happened the camera man (my friend) was bouncing up and down in the car so violently that you can barely see anything. But it's still cool Good times, good times. Anyway, damn that was a long message, I'm gonna go eat my chicken.

ok, so my bro has a '90 240sx and I have a '91 RX-7 base. basically if we were to race, he'd beat me through first and second due to the ~160 ft/lbs torque to my ~140, but high-end I would blow past him due to the HP difference.

He'd beat you low end because thats where his horsepower is, you'd beat him highend because thats where your horsepower is....but wait, I'm not gonna start this argument again! DAMMIT ITS TOO LATE! LOL

you raced the SOHC model...in other wards....SUCKS not that the DOHC is any better but race a real silvia (sr20 or hell even the CA18 is good mad high revs). In drag you have the upper hand no doubt...well maybe not i know the sr20 engine tops out at like 700+ hp with out nitrous.....what about the fc? i think the most i have seen is alf's 620. ether way the trany isn't made for drag its made for the circut which is were the REAL drivers race (that and the mountains ^-^ ).

Since when we're using $10k+ budgets on our engines?
Hell, in that case, the 13BT can do 700+hp also...

Get real - a stock block SR20DET can barely sustain 500.&nbsp It's about the same with a 13BT.

hey now i thought this was an rx7 chat. but while we r on the topic, my boy has a 97 240, cold air and 3" piping run out to a dragger muff. its quick but my rx will take him light to light allday long. it is when we r on the interstate, he switches into 4th and walks my dog. i dont get it, we r neck and neck until he hits fourth. his is an auto too. oh well my 2 cents.

You just proved that you know nothing. An SR20DET with 700+ HP? WTF? Their weak little transmissions can barely hold 400 hp at the flywheel. 700 HP took some GOOD Massaging of the engine...I don't even want to know what they did to strengthen the rest of the drive train.

Let's not even bring up the CA18DET vs. SR20DET debate. I've seen CA18DET's get the full treatment. Ported/Polished heads, rebuild block with Jun internals, Computer tuning, FMIC, SR20 turbine...ETC...and get beat by a black top SR20DET with just an aftermarket air filter and open exhaust!

i dunno much about the CA besides its ability to rev high. and what are you talkign about? i know that the sr20 will not do 700 with out alot of work. but what i'm am saying is that i haven't seen a 700 hp 13b. thats all. no the trany will not hold 700hp. i know that. so don't start flaming me. i love the 13b but i hate when ppl put down great cars liek the 240/silvia because they haven't proven them selves in the states. thats what this is really about. not a 13b vs sr20. PPL do not start saying ppl dunno anything because they didn't mention the amount of work. I hope no one out there thinks they can slap a huge turbo on a sr20 and get 600 hp. so dont' act stupid you know exactly what i mean.

700 hp FD. 2 Kilos on a T-88. Enough said. Just because YOU haven't seen them doesn't mean they don't exist.

Keoki-san, the SOHC is a better all motor platform then the DOHC. I raced countless DOHC 240's in my S13 and never really lost. As far as being better drifters, id like to see one of my former 240 colleagues put their money where their mouth is and offer some a challenge here in South CA (OC). No one on Zilvia seems up to it yet

i never said they didn't exist, i have said i have never seen on. sept for the video of a fd dynoing at 710 or 720 witch ever but wasn't that on a 20b. and as for a sohc and dohc ka engines. i dunno and i really wouldn't bother with them. i haven't had any personal exp. with ether one. jspec chill out you are acting like some one is attacking you and your rotory pride no one is. my original comments were posted on chassis and handling diff. hwo it switched over to engine i have no clue some on pushed me to it. fact is i could really care less which would make more. i really don't think i need 700 hp for anything but the highway and i'm very happy with 300+ witch both of these engines can easily make. point is 240/silvia hasn't proven its self in america and doesn't have as good a rep as it should.

I believe the Scoot FD has the 13B engine. The 240 doesnt have a good rep. in the US? lol its all over the covers of Import Tuner, Super street, SCC. They've turned this car into such a trend.

Really, thats not my purpose, but think about whats been pushed out there: Silvia for under 3k, SR20 swaps etc. Its pretty obvious that the performance aspect is what is being stressed

Yep, those SR20DET swaps are effin everywhere these days. Yesterday I went on road trip with about a dozen other cars. Check this out here: https://www.rx7club.com/forum/showth...4&pagenumber=4 (results of the drive are about 1/2 way down the page). One of which had a SR in a 240. One guy that came with a fellow '89 T2 owner had one too, but it met with a curb a little while ago so it wasn't on hand. I know another one locally that is presently under going the transplant. There are sooooo many more of them running on the roads in the Puget Sound area than I know about. Yep, I guess the word is out.

That 710ps dyno run on the Scoot FD is a 13B. It is on the Option2 RX-7 Special Video vol#33.

the s13 redtop and black top both can push 260 HP @ 14psi. the s14 can push the same and the s15 can get into the 300 range at about 18psi. I have a 240 with a redtop s13 sr20det and its a sweet car. i spent around 6k for the complete swap, greddy intercooler, xs engineering bov, greddy DP, clutch kit, wastegate, warlbro fuel pump, APEXi N1 catback, and installation, which i helped work on. Not too expensive for a car pulling 260HP.

Thats a pretty general statement "the s13 redtop and black top both can push 260 HP @ 14psi".
