well a few months ago my brothers friend bough an rx7 n/a that has been street ported with big exhaust ports, blaster coils, they put a carburator on it, and some other stuff. and every time he pass in front of my grandmas house(thats were i have my TII)he rev his engine and all i think on my mind was ''you're day will come lol" and well that day came today when i finally took my car to pass emissions and be street legal. so i took my car for a spin on my grandmas hood and out from nowhere i saw the rx7 guy in a house chattin with some guys, and i pass in front of them and give them a little bov action. well the rx7 guy got on his ride and he was on my *** revving his engine and doing some loud noise. so we got to a clear road and i told him '' let's see what you got man'' and he replied ''let's do it''. (but in the time my car was in the garage i put some extra good stuff he didn't know, i put the RB complete exhaust, safcII, and running at 11 psi.) so we stop side to side and honk three times and we were off, in 1st he had me by 1 car lenght cause i didn't dump my clutch, but when i hit second im at his door and gaining momentum and when i hit 3rd i was long gone, i beat him by 3-4 car lenghts and kept pulling but i decided to shut down. after the race he came to my side again and told me that he wanted another shot because he said he missed a gear, but i declined cause my safc isn't tuned yet and because i have heard does excuses many times and their dumb. needlees to say i think hes not going to rev his engine anymore when he pass in front of my grandmas house lol. its good to run against another rotary brother, cause there are not many here. but i think hell respect my car next time he sees it lol.

One sec, you denied a second race because you were untuned and you call them dumb?

Someone is making their own excuses.

I think a RX with F.I. would of done much better. You still would of won however.

rx7legend

lol theres no problem if my safc is tune or not, right now its like it was stock without the hi-throtle tuned. so im running stock only think i set the lo-throttle so i don't use much fuel when im not racing. but the hi-throttle is untouched. and bro i couldn't back down in the first one cause if i do then the kid would have been talking crab around the hood telling i didn't wan to race him cause i was scared and i don't want people talking crap about me and my car. and i denied the second race not only for the safc but for the excuse, he clearly didn't miss any shift. here were i live people that got beat always says the same excuse.i wasn't gonna race him but he was on my *** and i can't back down from a challenge. and one more question bro, whats a RX with F.I????

Er, all second gens have EFI from the factory and its like 90% better. Unless you have a drag car or something.

NOPR

so you were running 11 psi on an otherwise stock fuel system? or did i miss something?

rx7legend

i know bro, but the previous owner of my brothers buddy changed his f.i to a holley carb. and its a daily driver

rx7legend

yes on an stock fuel system and don't have any problem, the car runs great.

Jager

He just gained a little off the top end and lost something nearly everywhere else. Unless it was tuned great by a repuatable person I don't think it was much of an improvement over stock.

Jager

Er.

Your engine WILL blow shortly , its probably already dangerously lean.

rx7legend

lol no it will not, here all the rotary guys run like that even the dyno guy has a rx7 running 19 psi on stock turbo, on stock turbo, and hes been like that for a long long time, and you now what, he hasn't blow anything and hes benn like that for i think 2 years now. and you're telling me that at 11 psi ill blow my engine lol give me a break man. why am im gonna blow my engine when people here in PR run 14 psi on stock turbo with just a fcd and haven't broke even a screw. you can call BS but i don't care, im not here to tell lies but if you don't believe well thats not my problem. peace out

Xbladr

well just so u know the stock turbo isnt making much past 12psi after that it is so inefficient that its not doing anything besides pushing some seriously hot air around... just an fyi so hes wasting his time pushing the stock turbo to 19psi if he even really is like you say

Its not the stock turbo that is in question. Its the fuel system. Running higher PSI on stock fuel system will cause the engine to run lean as the fuel system may not be able to supply enough fuel to keep the a\f at a safe level as the turbo continues to supply more and more air. Too lean can cause detonation and blow your motor. Go ask the guy running 19 psi if he has done any fuel mods, I guarantee he has.

I'm not sure if 11 psi is enough to really cause too lean conditions. Get a wideband and find out.

rx7legend

lol im waiting for my egt to arrive, to go to the dyno and put the wideband on. and the guy with the 19 psi has a microtech on the car. i don't know if 11 psi is dangerous i was running 9 psi before i put the RB exhaust, but when i installed the RB exhaust the psi when up to 11. i will go to the dyno as soon as the egt arrives. another question, does porting my wastegate be helpfull or will it be better to put an external wastegate?????

Jager

iTrader: (10)

I doubt that.

So BS, I know how these car function and I know what you're saying is bullshit and misinformation.

Jager

You should be already having boost creep.

You NEED to port the wategate.

tjeter

dude, that guy is not running 19psi on a stock turbo, and i wouldn't tred those waters... 11 psi, do you have a boost gauge?... because you cannot control boost creep, even with a controller... what are your mods.. Turboback and what else? I doubt that guy is on a stock turbo, if he is that is just plain retarded.. and dude port your wastegate.. thats how i blew my engine didn't listen, i'm young and ignorant, also i wouldn't be running racing around in a untuned car.. do the proper mods first, go step by step.

rx7legend

bro he is running 19 psi on stock turbo but he sold the car recentlly don't know what the other guy has done to it but i think he took the engine apart and is going to port it, bigger turbo etc. and yes i have a boost gauge and my mods are the basics RB turbo back, safc, running 11 psi and im thinking of putting an external wastegate instead of porting the stock one. and i don't race on my untuned car in fact i only take it out on saturdays and maybe mondays. but the day that i took it out i got the bad luck that the guy saw me and he was on my *** reving hes engine and doing stupid stuff, and i didn't like it, so yes i run him i know i don't supposed to but the guy was bugging me too much, i ussually don't even race anyone but when someone is so stubbern and talking trash it makes anybody angry. im going to tune it, im just waiting to get the egt and i will go to the dyno.

tjeter

well you know it only takes one run to kill your motor just remember that, just be careful, you don't have to be racing it constantly detonation can happen at any time, also if your mods are only a turboback exhaust then boost creep shouldn't be too bad.. If i'm not mistaken why do you need an EGT can't they just tune it at the dyno..?

StinkyTurbo

HaHaHa...dyno in puerto rico?? Theres probably 1 dyno for the whole island of puerto rico & you have to be a somebody to get on it. All the cars out there that get tuned are mostly street tuned.

NOPR

your engine WILL blow up. how are you going to tune it? do you have a piggy back or standalone? you really think you can tune for 11+ psi on stock injectors? what are you going to do run them at 300% duty cycle? and a stock fuel pump!? seriously, you need to get a ******* clue or you will not have a car in two months.

also, an external wastegate wont do ****, and its not a bolt on deal. are you just gonna tap your manifold with a hole saw and weld a wastegate on there? the wastegate is inside the turbo, theres no place for external one without a new manifold. YOU HAVE TO PORT IT OR YOU WILL SPIKE TO LIKE 386423 MILLION PSI AND BLOW YOUR ENGINE!

but hey, if some guy knows some guy with a stock turbo that put down 600hp at 50 psi on an entirely stock car, why cant you?

adrock3217

The "dyno guy" runing 19psi on a stock RX7 turbo is full of ****. Myk (EAGE8) or here blew his at like 18psi. The average turbo on here will spontaneously IMPLODE if pushed over 16psi.

11psi on the stock fuel system. Maybe you're car hasn't blown up YET, but it WILL SOON. There's no way around it. Don't come back with a reply about why we can't call bullshit on you, because when it comes to you running you're car like a moron we CAN.


Lol..external wastegate on the stock turbo...x-D

rx7legend

hahaha , what the hell are you even talking about, 1 dyno for the whole island lol it seems that you have never come here do you, and dude you don't have to be a somebody to get on the dyno, if you have the money you can put a swift or wathever the hell you like. lol you have to be a somebody give me a break man, come here first and there start talking whatever the hell you like but don't talk trash if you don't know what you're saying, lol 1 dyno hahahaha thats funny, real funny.

rx7legend

yes i do have a piggyback(safcII), and i know what im doing man, i don't think that to tun 11 psi on stock turbo i have to upgrade my injectors tell me why??? or my fuel pump???? i think the safc is more than enough, and is like i said bro i say what i saw and i saw the guy running 19 psi, i do not have to be making stupid stories so i can be cool, that car wasn't mine if the car blow up well wth is not mine is hes problem. and yes i will port my wastegate. so youre telling me that to run 11 psi on my stock turbo i have to upgrade fuel pump, injectors???? for me, i don't know why, the car was running before at 9 psi and i dont think 2 more psi will do a hell of a difference. i think that with the wastegate port, the safc tuned will do fine.

EL5Letra

....my car is street tuned..and i have put a couple of T2's in their place...1 dyno..your an idiot..just like guy who started this thread . 19psi..stock turbo lol no wonder he sold it .LOL

rx7legend

damn bro, i said that i own a safc, and why the hell will it blow up man, i think that for 11 psi on stock turbo i don't have to upgrade injectors and fuel pump. with the wastegate ported and the safc tuned it should be more than enough c'mon man before i was at 11 psi i use the car as a daily driver and it was at 9psi without any modification and i use it as a daily driver for several months and i didn't have any problems. you mean 2 psi more will make a hell of a difference on a stock turbo. at 11 psi i added the safc so i can control the fuel and i will port the wastegate. and bro stop talking about the 19 psi, the guy run it i saw it, didn't blew anithyng, the guy use the car everyday and didn't blew, i don't have to be making stupid stories to make me cool, i saw the guy, i know the guy, i knew the car whats the problem man, the car did't blew up and thats it, damn man you think that because you say that the stock turbo cant be passed 12 psi everybody is going to do it. the car didn' blew don't know if its luck but to have the car like that for over a year i don't think that is luck. and why cant i put an ew whit my stock turbo????
