I am looking into my options for a fuel system when i go single. I want to keep the car very streetable in all conditions (turn key and go). I'll be going with a GT40-67 turbo, cams, etc....

Would it be more driveable to run lets say.. 550cc stock supra injectors, and install 1-2 addional injectors on the intake tract for when the big boost comes in, or just throw some 650cc sard or top feed injectors and let the FCON figure it all out for daily driving stop and go traffic?

 

Add an extra injector??

No.

Just get the FCON, get a full fuel system and tune it.

 

wtf larger injectors and change out your fuel system.

550 CC is large enough for most applications, the jump to a 650 isnt that great of a difference either.

 

I'd look into upgrading the drivetrain before going single... for example- upgrading the stock automatic you have, and the stock one wheel wonder rear end you have.... Keep either of the above and that single will be utterly pointless

 

I'm still waiting on my dam LSD... And my auto, yeah i know its crap. I got spares in my garage for when this one goes til i save up for a TH700r4.

 

agreed... and I'm in that boat right now. I can't find a LSD for my set up =(

 

I can get stock ones from japan for $250, but it takes forever to get them containered over

 

$250 for an A02B LSD???? Where do I sign up?!

 

is the stock auto that weak?? I mean who has really pushed it? and also i wouldn;t get AIC its a band aid for needed fuel requirements, youw ill regret it later.

 

The stock auto isnt THAT weak, it really depends on how you drive. On my older setup I around the 400rwhp mark and drove fine for half a year.

Of course if you beat it up all the time, then the stock tranny will not hold.

 

I got two spare 1JZ auto trannys in my garage just in case!

 

If i may ask why a TH700r4?

 

overdrive. They can be built just as strong as TH400. I had a 87 GN before i had this car. It was a common swap for 600+hp cars to get rid of the stock th200r4 and put in a th700r4. No GN's ever used a TH400. What works for them works for these motors, period.

 

Factory LSD's are like rocking horse ****.


I sold mine for £350 (just over $600)


Back on topic... get the sard 650's and have the Fcon set-up properly and you will be fine.
