how long have you owned this car? it does sound like you know a ton about modding cars.....which is fine, cuz everyone starts some where. just be careful when you get this single turbo installed, dont bite off more than you can chew, have a good time and have fun racing

[Chucky Doll]

Maybe I jumped to my conclusion to soon

In any case great choice of a turbo for your set-up. Get that baby tuned and learn how to launch. SP71 should take down the 7 w/o a doubt.

[TTSupraFanatic]

the FD will pull on you.... if its definately over 400 HP which he says it is.... now... supras are well known for their top end.. so im sure u can catch up when u get the single turbo. Now as everyone says... the weight is the difference...

hope u take some video when u guys race... it will be another good race between piston and rotor... should be sweet...

Notice I said practice your launches I wouldn't worry about a 7 out launching me

It kills me to see how narrow minded some people can be... a statement like that can only be made out of fear for the unknown! I have friends that have blown more motors in their Supra's then some of the RX-7 guys I know. Yes are they a little more tempermental than a piston motor in the hands of inexperienced so called do it yourselfers who use Autometer rich/lean gauges to tune their cars but in the hands of knowledgable tuner they can are just as strong and stout as the almight 2JZ. I know this from fact from building both cars and know the capabilities each one can offer. We have made 760hp on a simple street port motor nothing radical with STOCK 2mm apex seals which ran for a whole season and is still running if that matters. If this guy really exists and has a nice setup it is definately a force to be "reckond" with. The nice thing with the 3 rotor is it increases displacement from a whopping 1.3 liters to a unbelievable 2.0 not 50% more like someone earlier mentioned. But with that roughly 33% more increase in displacement you unleash a ungodly amount of potential to make incredible power but the best thing about this upgrade is the torque advantage. As we all know 2 rotor cars make no torque what so ever but with a 3 rotor you make just as much torque as you do HP. Combine all that in light body known for being able to 60' like no other and a good driver it would be very hard to beat no matter what you brought to the table. As you can see I have respect for both platforms because I own them both and realize what they can offer. I'm done ranting for now, its late and I tired GOODNIGHT!

just my $.02

Holshot

Your math is wrong. It is 50% more displacement. 50% of 1.3 is .65. 1.3 plus .65 is your 2.0 or close enough I guess. Remember the 3 liter coke bottles? They had "50% more" than a 2 liter all over them.

I've owned both an FD and a MKIV and all I know is I spent more time under the hood of the FD than driving it. Dam nice looking and was fast when working. Hell I forget what the motor in the Supra looks like. I don't have to worry about it!! A 3 rotor rx7 could get up to 700 whp if tuned right but won't last nearly as long as a 700 hp supra plus you would pay out the ass for a built 3 rotor and have to work on it day after day.

Just my .02

i've been into modifying cars since i was 17(9years ago), my last car was a subaru impreza wrx and i blew up the engine once, blew up 2 gearboxes to decide that i need an unbreakable power generator, i considered the RX-7 as well but was too small inside compared to the supra and u do see them quite a lot around so i wanted something differrent thats why i went for the sup. I've spent upto date too much money in modifications(not just for the supra) and its like a virus once you get it-its very hard to get rid of it. Now my plans was a big single(yes i think an SP71- 850RWHP considered to be a big single thats 1000HP@the flywheel!! for god sake, i dont think there is any other car which can produce so easy this kind of Bhp). Anyway my plans for the sup was to get a single like an SP67 and stay with stock bottom end, get up to 1.5-1.6 bar along with a thicker head gasket and be safe with 600bhp. Then i thought of my friend who is a very good mechanic in terms of engine rebuilds and fitting kits, had a word with him and realised that you either modify a supra or keep it with stock turbos with 400bhp and finish. So after checking out prices for forged pistons/conrods i thought best is to get the dream car which i always wanted since i was a kid a mean fast street racer. I believe life is too sort not to do what we really want, so this is not just about my ego or me being selfish but its what i really want.

Now if i get titanium valve retainers and double springs, i can rev it upto 10000REVS!!! thats going to be a turbocharged Ferrari engine sound!, then we'll work on the block port/polish head, light and balance the engine then the RX-7 can kiss my a**. I bought the other day a Race logic traction control with a launch button. That means you deep the throttle all the way to the floor, it holds the revs to about 4,000 and then you release it and it accelerates with the least possible wheelspin! you can even set the percentage of the traction u want to have 10,20,30 etc. Along with a Cusco LSD and some good tyres i think i will launch quite good!, if he has 600RWHP i will get 850RWHP, we see which one is lighter

[TheDane]

This is just like a "1-supra" tread!!!
I dont have the kit yet but maybe im getting it!
Allmost all single supras witch are tuned correctly will run from a 550hp Rx7, those rotery engines have no tourge!!!

And that guy from Thailand SHI: SPL and t88h
:dienewbie
A 63mm turbo tuned right will do the job...

[Chucky Doll]

Agreed, RX-7 may have a weight advantage but where in the hell is the torque? Leave him out of hole and never look back

Meh....why not let the car drive itself? :P I'm playin, it sounds like a neat trick for serious dragsters but I mean with that plus an auto tranny what is left for "Driver skill" other than being able to depress the accelerator? Heck....

You are probably spending close to 7k if not more just to beat a stupid rx7 in a race.

man you got some weird priorities.

[supra700]

Emm yeah i guess you are right, i do have some weird priorities, but its only because im still young, single and have n't got any other worries or obligations..I mean if i dont go mad now when will i? when im 35+? i still have time to get serious(few years) hehe

PS1 I have paid for the SP71 im just waiting on it.. its not an IF thread..

PS2 I would love to hear the Supra screaming out of 9,000 revs. I dont think there is anything else in life apart from SEX which gives you that kind of pleasure. Its not just only about beating a stupid RX-7...Did i mention? Last year while i was in Greece on my holidays i beat a diablo RWD (490BHP version) by a car..Remember? Challenged by a diablo thread 6 months ago?), i only had 400bhp+....right the guy got so pissed off that he sent the car to ITALY to modify it!! he got like an ECU, cams and shit like that just to beat me this coming summer!. So i have another serious opponent which i have to teach a lesson. And this time i will have my camcorder with me.!!

Congrats on your new setup.. I have the SP71.. untuned on 20psi on pump gas I TORE up my friends 03 Cobra w/ exhaust. Its getting tuned this springs with hopes of 750+ rwhp

If he has what he's claiming, you're never really safe. There's a reason those cars are so fast with so 'little' power (relatively speaking), check the weight difference. It's like David(RX7) vs. Goliath (Supra). The RX7 being the far lighter of the 2 and the Supra being the beast with the raw power. I don't want to open up a new can of worms, but from the general idea, PEAK HP doesn't win races, it's where that power comes in and the area under the curve, weight, traction, etc.. This is why a lot of similar HP Mustangs, RX7's, etc will pull away from Supras... The RX7 might be down on the power, but it makes up a lot of ground in the weight department.

LEMAR

[black2na]

be warned that 3rotor 20B makes Very Good power and it is not a power made at 9k RPM it is made through out the powerband in stock form the 20b makes has much power as the 2j and if it is the an FD you are gonna have your hands full the RX7 is one of the most underrated cars ever made. so watch out. and that is a mildly tuned 20B which came out of the enous cosomo have seen some with the range of 8-900hp. and yes 9 times out of 10 people who take the time to put a 20b in an RX7 take the time to rebuild them. with 3mm apex seals, brigdeported. and race bearings. so be warry it will be a good race.

[supra700]

I know what you mean, but even the guy with the Rx-7 said that if i have over 750bhp it will be a tough one..He doesnt know though that im planning for 850rwhp+NOS! thas over 1000BHP!, i dont care what he is got i'll give him some..

Shit man, you don't need forged internals for an sp71. I do believe that 850 wheel is definitely a slight bit optimistic for that turbo...i'd say it probably gets maxed out around 825...but hey, i'm not sure.

As for revving to 10k. You have to watch piston speed. This is what more often than not blows engines...especially supra engines. Revving too high will put too much stress on the engine. Only rev to where you need to rev to...dyno your car and find out your shift points. Unnecessary revs is unnecessary unreliability.

[supra700]

yeah i know, i would say i will get it to rev safe around 8,9...

I'll be doing the video coverage of the race when that happens
supra700 i'm gonna bitch slap on the spot you if you lose

Guys,

I've been challenged by a triple rotor rx-7,he reckons its around 600bhp,at the moment my car is very slow (400bhp) and my plans is a big single for 700-750bhp+ +NOS,my friend went into that RX-7 and he reckons he is going to kick my ass, he says the car launches and goes like a rocket(NO NOS), has anyone had any experience of an RX-7 over 550BHP?????? He recons he does sub 10 1/4 mile!! how is this possible???????????

IM GOING NUTS, i thought a 750bhp supra can take on anything

Has anyone seen any of those bloody RX-7?? The funny thing is this guy is very annoying and he really underestimate the Supra, he says even a 500bhp RX-7 can beat a 700bhp Supra!!!

Tough call bro..weight to HP ratio
600hp RX-7 = 4.5 to 1 (lbs. per hp)
750hp Supra = 5 to 1 (lbs. per hp)

[supra700]

So i will need at least 200bhp more to give him a good race...Well i think he will have one,if everything goes according to plan i should easily have over 800RWHP+NOS for low down..HE has to do something special to beat me...

**Im planning of rebuilding the engine point to point, gas flowed head, exploit every single bit of the 2J, i just found out that my mechanic is using a guy for the rebuilt who is dealing with GT ART, means rebuilding skyline engines!! including the recent 1000BHP skyline in the UK. I could use his help!..He was telling me about working on the crank as well and lighten and balance the engine. Before the race i will rip everything i can off the car. I was also thinking of throwing the current supra 100KG seats out and stick 2 lightweight ones along with a carbon fibre bonnet..THis should save me some weight...

PS Im also going on diet , this RX-7 guy apparently he is really fat hehe.

[eyefi]

what u gonna do if u loose after spending this £10-15k?

[supra700]

Nothing,im not doing this conversion just just for this race, i was going for a big single anyway,probably i would have left it alone at 600+bhp,the only thing which will cost me more is the extra 2,500K which i will spend for internals and anyway then my car will run safer and i will know that the internals can take the power,so no big deal!.My first aim is to beat that modified Diablo...I realise that it really depends on how much BHP is that RX-7, i realise that if he is more than 700RWHP i've got very few chances of beating him..and i still dont know if he has a triple or twin rotor in his car, he said in the beginning that he has a twin rotor and his friend's 7 is a triple which he wouldn't even discuss it racing with me!. I agree triple is kind of unbeatable, i wouldnt think a triple motor would be less than 700-800!, i've seen some scary clips of those 7's doing 8's for a laugh at 1/4 miles. They are very light and they are unbeatable..I just hope that he tells the truth and his car is 550-600 which can be matchable from a 800+ supra. The difference is that if tuned right supras are unbreakable, you can un low boost for every day and take it even to a supermarket for shopping!, you tell me another car which can do that....and get all this power so reliable and safe!.At the end of the day the conversion will cost me around £10K+13£K to buy it, for 23K find me another 800bhpRWHP for everyday use!!!

I dont think there is anything else on this planet....Hell yeah its worth doing it.
