Anyone know exactly how you make Mk3 440cc injectors work in a SC300? I know you need a resistor box, but does anyone know the part number of this box? And you only need one, correct?

 

Stock sc300 runs 330cc injectors. By upgrading wouldnt you run more rich? Are you na-t?

 

Why do you want to run bigger injectors? Unless you're going FI, it's kind of a waste of time and money.

 

Thanks for the concern, but if anyone knows how to do this, please help. I know it's been done on the GE's plenty of times but I'm having trouble finding info on it.

 

iirc mk3 uses 440cc or something similar .

 

Solder in some inline resistors or get a resistor pack for the injector easy day.... Upgrade maf or go speed density aka map and iat

 

look on a supra site in the classifieds, or find a calculator online to figure out what resistor you'd need to make this happen. You'll want to wire these into the power side going into the injector. Go to *******.com for any part numbers yuo ever need

 

Does anyone know the resistors I would need? That is what I'm here to find out.

 

use multimeter and determine resistance of stock resistors. Use same multimeter to find mk3 resistance. Then use online calculator to determine what you need.

 

Ps: it literally took me 5 minutes to figure this out on google

10ohm, 25w or better (I have 50w personally)

Stop being lazy and looking for handouts. You won't learn anything that way

 

Or maybe just get any Honda v6 resistor box and wire it in. gl

 

Quick comes through with good info as usual. Usually like $7 at a pick and pull. Cheapest route probably.
