Fc3s with sr20det conversion
 
I was wondering if there has been a sr20det swap in a fc3s before?, and who has done it.

poor_red_neck 10-21-06 03:13 PM

Umm... I dont know about a sr20... there has been a supra swap... I don't remember if it was a 2jzgte or a 7mgte though.

Why the hell would you want a sr20 in there??? If you're going to do a swap, go ls1.

snowball 10-21-06 03:18 PM

the 7m guy quit before he finished.
sr20 has been done. their is a guy looking to sell his sr20 swap setup or trade for nice 13B-T setup.

vipers 10-21-06 03:20 PM

yup..been done.. theres a drift car fc out there w/ an sr swap.... and there are a few fd's w/ that swap

Rotary Noob 10-21-06 04:36 PM

Dont know why you would want to do that though...Its not a RX if its not a rotary....it just kinda kills the whole feeling of the car in my opinion. To each his own though.

buy a 240 sx, dont ruin the rx7

Turbo23 10-21-06 05:44 PM

Chris Forsburg and Tony Angelo both ex falken team drivers, and northeast rockers did the first SR into a FC swap about 3-4 years ago. Someone on the forum now has the car

don iz will 10-21-06 06:36 PM

? i hadnt seen that done b4 but y would u do it? i have however seen s13 silvia's and 180sx's with 13bt and look here's a 350z with a 20b :) http://www.youtube.com/watch?v=LdrpwrN9daM

If you really want a SR powered Drift car, convert a 240 over to an S-14, or better yet, make yourself an S14, put the hikass 4 wheel drive system in it, and throw in an RB26.

Besides, the RX7 is a good car, but if you put a 4 banger in there, its still just another ricer. Even if ex Falken team members did it, doesnt mean it looks, sounds, or acts right.

I think an LS-1 Conversion would look pretty bad ass, if you kept everything under the hood, and youd get more power out of that than you ever would in a wimply little 4cyl. Go Corvette powered, those FC's move pretty damn quick. I think theres one in the 8 second club, and a few in the 9 second club. I know they have the power to over steer the car. Hell, the LS1 will kick the ass end out on my vette if ill let it.

Seriously now, if you want to make a drift car out of an FC, do it with the rotary, or it just doesnt count. It would be like a plane running nitrous oxide, it would be retarded. But again, whatever you plan on doing, more power to you, and have fun with it.

don iz will 10-22-06 04:02 AM

why would he wanna put in hicas 4 wheel STEERING in a drift car? hicas is the first thing drifters get rid of on nissans .and yes an rb26 would be nice in a drag car but would throw out the weight balance for drifting. stick with the rotary if u buy a 7 for drifting m8 u wont regret it

Rotary Noob 10-23-06 09:03 PM

I have a friend that built a 240 as a drift car. Insane 240. Was running a SR20Dett, and was looking for a RB26, couldnt find a good block though. He had the Hikass system in it, (as well as the Attesa E-TS). I could be mistaken, but thats what he told me. This subject isnt talking about "The RX7 is a great drift car", no one is disputing that but theres no reason to put an SR20 in it.

And the RB26 has much better torque than the SR20 could ever hold. Ive said my two cents worth now, anyways, wish you luck on whatever you do DCsilvia

(Note:I said Hikass, yes, I meant Attessa E-TS, i dont know nissan, or many other such "import" cars, mostly because i hate them, Stupid 4 bangers. Just did some research. Yes you are correct, Hicas is a rear wheel steering system that can modify the rear wheels up to 1 degree. If you think about it though, thats basically like the Dynamic Toe in that the RX7 currently has. I knew people that could drift with that too, just a little harder to break the rear end loose according to them.)

(Second note, since im editing, and i see what this guy below me said.)

I agree, that while the car was not intended for drifting, if you change out the one suspension bar that controls the dynamic toe in, it works rather well for it. It is a great handling car. In the time i have drivin mine, it handles rather well, not as good as the corvette i drive daily, but not too shabby for the tires that it has, and the fact that its an 88.

Weight distribution wise, it is almost perfect for drifting however. Since it has a near 50/50 balance. (off by .2%) Also, if you keep the tires spinning, ther eis no violent action. If you keep it oversteered, and then straighten everything back out at the end of the corner, theres nothing more than the kick of your tires hooking back up with the road.

but yes, this car was built for handling.

Whizbang 10-23-06 09:07 PM

im going to say this.

the rx7 is not a great drift car. it is actaully designed to NOT have the ass end go out and makes for some very violent action when it goes over the limit.

a great HANDLING car. yes.

KaoticFdR1 10-24-06 12:13 AM

it's your car do whatever the hell you want with it...read the opinions that come from experience rather than speculation. Don't forget your thigh high rubber boots too.

Nihilanthic 10-24-06 12:52 AM

You can, but I dont know why you would want to unless its reliability or cost related.

The only real advantage a SR20 would have on a rotary is possibly relability and fuel economy, lol. I guess for a street car it might be a good idea, but if this is for RACING you might as well keep it a rotary unless you just like to go "SHAZAM ITS GOT A 4BANGER" *Crowd goesoohhh!!!*

Basically, yeah, FC's by nature are just perfect for any kind of swap you can think of by their nature of being... a rotary car (oh the irony) and just well set up period. You would just have to eliminate the passive rear steering with bushings, modify the steering to get a bigger angle, and then do the usual doriftu modifications in addition to the swap.

But again, practicality screams why not use a 240?

don iz will 10-24-06 05:54 PM

sorry but your friend must not like doing things the easy way a drift car with attessa and hicas would be very hard to drift ever seen any gtr skylines drifting?.u can drift with just hicas but it makes it alot harder and unpredictable cuttin in mid drift and generally pissing u off i've not seen one australian drifter who does it professionally who uses hicas and if amatuer's have it its coz ther poor and cant afford a hicas locking kit.

Rotary Noob 10-24-06 06:35 PM

Thats true, he doesnt like doing things the easy way, he was making a DTM car out of a Mercedes 190 the last time i talked to him. Had to sell the 240. He could get it plenty sideways. And yes, i agree most skylines dont drift, but i saw one sideways as hell one night i was out racing. He had a dyno sheet with him. 800+ hp. but anyways, this is kinda derailing the thread.

I shall say it again,

Do whatever you would like to do with your RX7, in the end it is yours, and as long as you are happy with it who cares what it has under the hood? Enjoy your project, regardless of what it may be, and best of luck to you.

(Please PM me if you have another response to everything thats been said, by me.)

rarson 10-24-06 07:01 PM

You guys claiming that the RX-7 without a rotary in it is "just another ricer" are not giving the FC3S the credit it deserves. The fact is that it's an awesome chassis and some people would rather have a different engine in it, whatever the reasons (there ARE legitimate reasons to swap out the rotary to plenty of other engines, not to mention the biggest reason: OPINION).

The original poster didn't say anything about drift, so it doesn't really matter (and in fact, could be a plus) that it doesn't drift well. If the car in question is being built for "grip" driving, then an FC would be a much better choice than an S13 or S14.

Another thing is that people often overlook is power. Sure, an LS1 may be able to make more power at the very extreme end, but how much of that power do you need on the street? Do you really need more than 350 whp? If your answer is yes, then my next question would be "Have you ever driven a car with 350 whp?"

I'm not saying the SR20 isn't capable of big power, but I'm saying that it's a moot point. People would have much more fun with their cars if they focused on all aspects instead of chasing magic numbers.

Whiteclipse 11-30-06 01:56 PM

I know you guys frown upon this swap in general but i already got my Sr20 waiting in my garage to go into my Jdm turbo II, i have a N/A fc as well so im keeping the rotory spirit alive still I was wondering if you guys could direct me to a member on this site, or anyone else you know that knows the specifics for the swap, thanks much :)

Ah, you steal my heart.

The S13 and 14 both have a double wishbone rear and is far superior to the rx7's multi-link (maltilink for anyone with an FSM :D) rear trailing arm suspension

Plus, the Kouki S14 looks better then an FC, and they are cheap as shit to buy and swap. Under 10 grand with the motor swapped and some goodies including the price of the car. I doubt you're going to beat that with an FC.

Furthermore, with all the dyno charts of KA-T motors I've seen, I wouldn't even bother with an SR.

McRussellPants 11-30-06 02:34 PM

FC may not have been "meant to drift", whatever that means, but it does it nicely with more angle and the DTSS removed.

rarson 11-30-06 03:22 PM

Yeah, but if you want big steering angle, you can't come close to the S13, not with an FC. Even stock it's got more angle than a modded FC could get.

Right, me neither.

The only time the car drifts nicely without alot of "snap" is when the car is transitioned on the center axis of the car. Reted has some nice writeup information on the theory of FC drifting tactics.

uhh... no.

a kouki S14 ALONE will run 8000-10,000

an S5 TII will run more around 5000-6000. and S4 TII can be had for 3000-4000. this is with a very competetive chassis, equally powerful engine with similar potential, better brakes standard, LSD standard, etc. explain to me how an S14 is even close to being better for the price?

sr20 is overrated
