i have a 88 mazda rx7 turbo II streetported block
stock ecu
cone air filter,
3 in exhaust, rb
720cc secondary injectors, 550cc primary,
to4b .96 p-trim,
stock intercooler right now i am running 5lbs and it spikes at 6lbs of boost,
trany is getting rebuilt with a stock pressure plate and 4 puck sprung clutch
i ran a 13.8 in the 1/4 mile, i want to run low 12's high 11's with street drivability with under 20 lbs of boost

what modifications would you guys recomend to get this

i have 17's on also if that makes a difference

 

fmic, standalone

 

Ditch the ECU, ditch the turbo, ditch the injectors, ditch the fuel system, get a GOOD quality front mount.

 

damn dude you did this **** *** backwards... I know a guy who ran a 13.1 with stock turbo, stock intercooler, and stock ports. He had an Rtek 1.7 ECU tuned with an SAFC.

 

**** i've ran a low 12 with a stock turbo, that's irrelevant. Still doesn't mean it's not inefficient and dumb to do!

 

ditto stock turbo but front mount but boosted i think 11

 

WTF is up with the FMIC posts and think he will run 11s maybe in the 1/8th!

SonicRat naild it the first time "not that it wasent exspected" BIGER TURBO! a real fuel system a good tuner with a EMS and FMIC will be the only way to reach 11s

 

Hmmm... 11s under 20 pounds of boost on a stock port *might* be a tad difficult. Not saying it cant be done, but it wont be easy. Right now, I am cranking out mid 12s, but its taking me 17 pounds of boost with alcohol injection to support this. Also, keeping in mind that I am at 3000 Ft MSL, so if your track is around sea level, you can add .5-.6 seconds to this time. `

 

He has a streetported engine.

 

when you go to ems and ditch the stock AFM you will flow twice the air you do now

 

Bigger turbo (minimal T04E 60 trim, or 60-1), front mount (or at least a w/a system), standalone, upgraded fuel (bigger pump, larger injectors, FPR, etc), a good tune, and a stock pressure plate with a 4 puck your saying you might use won't hold the power required (at least 400) for an 11 sec pass. You'll need at least a ACT HD plate and either 3,4,6 puck or extreme plate with an organic or 3,4,6 puck

Yep, I missed that....

 

11's? Big turbo. Willing to hold 20 PSI of boost without a problem. BIG FMIC, 2.5-3" thick, one the big honkies. Intercooler piping 2.5-3". Relocate battery for a cleaner shot for the piping. Upgraded radiator, Koyo or something of the like. 720cc primaries, 1600cc secondaries. Walboro fuel pump, and rerun the fuel lines. If you want a really nice pass, slicks . Standalone (Haltech, Microtech, or Megasquirt n' Spark).

 

low 12s can be done on a TO4B. You will need a FMIC, EBC, Standalone ECU and some more fuel.

 

some slicks, atleast a t04S, a fuel system, and a haltech.

 

low 11s sounds like you'll need about 450rwhp area.

 

thanx everybody for your input

standalone ecu? would a microtech lt8s be sufficiant for that
how about 720cc injectors for primary and secondarys with a walbro and tuning

 

allso 7.5+ grand in new parts + dyno time and a tuner and any labor not self done. Some mean tires to hold that HP down.

 

try 850P 1600S on a 78 trim and 1300 on a 60trim

I do not follow microtech but IIRC the lt8s is a fuel only system and will not do the job.

 

dude, wtf are you talking about?

 

The LT8S is fuel and ignition..

 

Awsome thank you J-Rat I will make a note that that one is the good one.

 

Umm.. thats only one of many models they offer in Fuel/ignition... I wouldnt call it the "good" one, its just one of many..

 

Interesting statement. Do you have proof of this?

Since when?! This is incorrect. This is also the absolute last warning you will get regarding misinformation. If you were unsure, all you had to do was look this up on the Microtech site. Instead, you posted anyway knowing fully well that the answer may not be correct. This is unacceptable.
