i have a 82 with a 91 13bt going in with a BNR stage 2 to4e turbo and a big front mount.

i want to run about 12-15lbs of boost to start with, I dont plan on going past 18-20lbs.

Im thinking the standard 1600s of the secondarys and move the stock 800 secondarys (right??) to the primary.


does this sound good.

also, what fuel pump would you recommend. It will not be a internal pump as I have to use a GSL SE tank or a cell. I have heard people recommending a Bosch pump but I couldnt find any info in my search.

 

A 91 13BT should come with 4x550cc injectors all the way around. The only bigger stock injector is the 680cc from the GSL-SEs.

I take it your running a stand alone ecu? But ya the 800 Prims and 1680 2nds would be the way to fly

 

yeh, got a haltech on the way.

Im thinking of running the engine totally stock except for a upgraded turbo(mainly for cost but also for siplicity) and then go from there. This is my first experience with stand alone. so Im thinking this is a better route. then when I get a hand of tuning the system I can upgrade the injectors and start upping the boost.

thanks for the info,


what about the pump, I saw a aeromotive pump on summit but it seams way overkill, is there a cheaper alternative. i keep hearing about bosch pumps.

 

The stock 800cc injectors from the FD are side feed and wont fit the FC rails which use top feed injectors.

The biggest 'stock' injectors you can get come from the GSL-SE's. Some had 2x680cc and some 2x720cc injectors. Low Impediance.

 

all se's had 680's

 

cool thanks

 

np

 

Just get some 1680's and 850's and you'll be set

for stock like setup u can go with 4 720s they plug right in and it should do the job until u r ready to upgrade it.

 

how much power can I make with 720s all around, and where can I get them.

I doute ill ever exceede 300hp or 14-15psi

 

Ive seen guys posted that they have made 300-350 with the 720s.....as for gettin them u can try the rx7 store or rc engineering. Im sure there are other places but im not sure of them at this moment.
