-Yes, i am on supra TT injectors right now. They drop straight in, but as mrdriver mentioned, i had to upgrade the fuel rail as well. You "can" use the stock fuel rail with them...but i wouldnt want to test the stock rail with bigger injectors over 300rwhp or so, due to pressure drop on certain injectors.


-You do need a fpr with the gen II ecu. Unless you plan on making rediclously small adjustments. If the ecu finds out that fuel is being pulled by a piggyback, it will advance the timming. So say do you throw a safc on there...you will most likely lean it out a whole lot..and there goes the ignition advance, and poof...there goes your engine. What you have to do with the gen II's is use the afpr to LOWER the fuel pressure, then come back and use the safc to ADD fuel in. This way you get around it advancing the timming on you. No mr2 people have really ever tried to use over 550 cc injectors with an safc setup though.

- Our mr2s loss about 15-20% (more closer to 20% usually). Usually stock gen II's will dyno right around 160rwhp, and with 200 crank hp stock, that usually just about 20%. So he could definetly get 300 crank hp, because all here would need there is 240rwhp (at 20%, and even just 255rwhp @ 15%). My mr2 was doing 245-250*ish* to the wheels with just my cheap ebay intake, ct20b at like 17/18 psi, and just a open downpipe. Stock everything else (fuel/ecu/intercooler) So i imagine with a decent intercooler and maybe a could other little things here and there...it coudl of seen better.



Love Doctor- I say dont go crazy for now and start shooting for 11's right away. Take your time and enjoy the road along the way. A mid-12 second car is impressive to be driving around everyday on the streets. A select few..mayb even only ONE has touched 11's without a stand alone, and that was jecklandhyde on the mr2 boards, and his car is a freak. It shoudl of died by now..but whatever, plus hes a good driver, and set the rest of the car up well too.

But the bottom line is for any kind of real power you are going to need a stand alone. The 550's CAN get you into the 11's (again, there are a number who have done it), but you need the rest of the fuel system built to really max those 550's out (which with everything well-done (pump/rail/fpr) the limit is right around 360rwhp. I would say pick up a nice turbo kit (like the ko racing t3/t4 kit) or maybe something from atsracing, get some fuel on it, get a stand alone, and do ot properly the first time, so you dont have to save for an engine rebuild. Power is expensive.

Or, just put a bad-ass fuel pump in there and run a 150 shot of nitrous.


I personally am working to get into the 11's right now. Im doing 12.7's BUT with a F*ed up tune, and on about 16.5 psi on my tdo6 20g. Lol, im on a walbro/afpr/upgraded fuel rail/and 550 cc injectors all on the STOCK ECU (lmao) i dont even want to know my a/f ratio. I have to replace my plugs everyother month just to keep the car running.

My stand alone is all setup now though (SDR cost me 800 dollars by the way), and im going to see if i can have xat tune it this week or maybe weekend. So, when i plug the sdr back in (all sensors and everythign are connected, i just had a software issue that i just worked out, but while i was doing that i had to run around on the stock ecu because it wouldnt let me upload the basemap)..anyway, when i put that back it, ill seafoam the shit outa my engine (to get rid of all the buildup) and go have it tuned on about 19psi (os so, maybe 20 is things looks good), and see what i can do from there. My car does have a good bit of weight reduction though (approx 230lbs) so that will help me at the track)

Alright, thats my input.

 

Hey what's up dylan,
This is robby that guy who recorded you and the viper going at it.
My friends with there supras and there friend are havig a big group dyno day at xat on june 4th for 30$, the only bad part is that you only get two runs with a wide band. That's not to good for tuning.
That would be really cool to see some mr2 dyno. I think i mite, just to get a base map before i put my t3/t4 on and everything else.
So let me know.

 

Hey whats up man. Thanks for the heads up, i might be interested in that, but ill see in a week or so what my plans are. Also it depends on if im tuned or not yet, right now the more i drive the more spark plugs i go through, i need to get tuned before i waste another set, lol. I dont think my mr2 would match up to some supra #'s but maybe for fun, yeah ill def let you know.

 

That would be bad ass.
Try to make it.
I watched some guy dyno his 240 that new you. Acually i think it was his friend. He said he grew up with you. He's darker with long hair and drives a civic si, really cool guy tho.

 

I predict a 14.0 flat if you can get a 2.0 60' or better. You still have the stock cat, stock clutch and street tires. Plus your car is full weight. If you get a faster time then 14.0, I will congratulate you, but to do it, you will need 1.8 60' for sure. My recommendation would be to launch high in the rpms, around 5500, let the clutch out slow, let the tires spin just a little. If they spin too much, just push the accelerater less until it grabs. Good luck!

I ran a 12.90 on a usdm gen 2 with 54 trim ct26, act stage 1 clutch, intake, gutted cat, stock exhaust, blitz ebc @16psi, and gforce ecu. I had a 1.82 60' and trapped 106. I estimate about 235-240rwhp. This was done in a 93 n/a ttop chassis. Only weight reduction was removal of spare tire.

Dylan is correct about the safc, it is useless on a gen 2 without the fpr or vpc. Also, when using this device, any small leak of air through an intercooler hose while going down the track and bye bye engine. Air is metered at the intake, and can be lost anywhere in the intercooler tract if you have worn hoses or pipes. This is why a stand alone is so necessary for a Gen 2.

11.8 was run on a ct20b, by Brian Moore. He had a completely built Gen 2, all the piggy backs, fat drag radials, dyno tuned to around 320rwhp, 91 n/a chassis. low 1.7 60'. Basically a perfect run down the track, trapped 115 mph.

 

Sorry for going off topic.

 

Will open another post later for Results. Thanks again for all of your input guys. Wish me luck.

PEACE-

 

hmm...was his name "trini" by any chance?

Other than that i dont know who it could be..didnt get the name by any chance did you? Huh..small world

 

I can't recall his name, I just saw him at a supra meet last week, he came with some homeboys if you now what i mean.
