Thx
So to make everything clear. The instalation is just the same as the oem injectors.
If you buy new oem seals everything is ok.

Yes exactly.

Also remember 2 pieces of this metal washer 23232-41081. Between fuel line and rail

OK now i have my air fuel ratio meter installed.

my setup is
145 mm pulley
1zz-fe injectors 250cc
patricks blackbox
de-cat manifold and de-cat exhaust
bigger intercooler
IK22 spark plugs
cold air intake
aem wide band Failsafe gauge ( air fuel ratio and charge pressure meter in one )

Running 0,5 bar pressure near the rev limiter with 145mm pulley

when i am at idle my air fuel ratio is 14,7
when on half throttle the air fuel ratio is between 13 and 14,5
this seems very normal to me because the oem ecu is always setting the air fuel ratio automatically to 14,7
But when i press my foot down the air fuel ratio is at 13-14 till i reach 4500 rpm
after 4500 it is making its way down to 13
after 5000 it is 12
after 6000 till the rev limit it is between 11.8 and 11.4

can some one tell me if these are good numbers? because i read some articles about air fuel ratio and I always hear that with supercharged engines air fuel ratio of 11 - 12 is good but i only see these numbers when i pass 5000 rpm. I thought it would be richer on the lower RPM.
Or is this because i still have the oem ecu and the oem ecu is always getting the air fuel ratio at 14,7 because of fuel economics.

thanks stav for the quick answer! the car runs good but i was a bit worried about the numbers. so you think these are good numbers. then I stop worrying.
So If i see these numbers i dont think i need bigger injectors like the 2zzge injectors.

I would also say the numbers are really good.

At 6000 rpm or above I'm between 10-11.

Great setup btw.

I'm still waiting for my decat manifold. Did you notice any difference after you mounted your decat manifold?

hi
actually I decatted my oem manifold. Also have oem exhaust with a straight pipe instead of the catalysator welded in.
I did notice some diffrence. It pulls a bit better in all revs. just because the catalysts are very restrictive and the are now removed.

Arh ok I see. I have the sports cat from toyosports and soon the decat from toyosport. Cheap brand but I have been satisfied with the sports cat.

I have seen these manifolds before but the reason i didnt buy it is because there isnt a bolt point for the bracket for the superharger. You should weld a bolt point for the bracket on it
