JZW Stg 5 viggen E-85

Changed tune to E-85 and the extra torque and power is really nice. Here is a couple of acceleration pulls from 50-80mph, its a tick faster now :-) Very smooth power and it pulls higher into the rpm band, I love E-85.

I'm sure its just injectors and a re-map.

maybe better fuel hoses. i' don't think it takes that much to be honest .

This viggen had a walbro 255 fuel pump, 3.5fpr and green giants and custom ecu tune for E-85. Many tuners go with the 60#but made this car work with green giants.

lol ok .

you don't need to get a fuel pump and fue pressure regualtor, this is only if you want to tune it. if you just wanted to convert you wouldn't need these just inkectors and a re-map.

what sort of power you making with all that fitted though. ?? sounds cool

I have yet to convert to e85 without a tune. All was necessary with the tune and 19t turbo on the car. he made 310whp and 420 ft-lbs of torque with that set-up and the green giants were maxed out even with the walbro 255 and 3.5fpr, which is common on stg 3-5 tunes anway. You could go 60# without the fpr. That is what I do with flex fuel 95's that I tune.

Is this on the stock b235r piston? I think i need e85 and a 19t :) This 15t just aint cutting it anymore.
