Question about upgrading fuel system
 

Ok guys, what is the best/easiest fuel upgrade out there that can support well into the 400rwhp range.

I want drop in injectors and drop in fuel pump. What is the most reliable and easy to deal with.

Also, how much of a pain is it to install new secondary injectors???

Thanks

850cc in the primaries good for about 380-400hp, or upgrade your 850cc secondaries to 1200cc (or whatever flow rate RC is getting now). Supra tt fuel pump, too easy to install.

I've heard that about the Supra TT fuel pump, how much hp is it good for??? Does it just drop right in with no problems??? Where is the best place to get one and how much are they?

I'll probably go for some 1200cc sec inj that are drop in. What is the best inj out there???

Thanks guys,

I would like to know too. any idea about cost for the supra pump? any other pumps that would work just as well, like the Walbro? would one have to put in an aftermarket regulator if the pump were upgraded?

Sorry for all the questions.

Thanks

Hi Stephen,

Chris @RP told me 850cc injectors all around are good for about 400 rwhp. He said his shop can mount the secondaries in place of the smaller primaries for minimal labor costs. I'm looking into buying some low-mileage 850s and sending them to RC to get cleaned. With stock turbos, a 400rwhp fuel setup is good enough, in my opinion.

I have the Walbro pump and have no complaints. It was $128 for everything incl. s/h and tax. It was a drop-in installation. No aftermarket regulator needed w/the Walbro.

The Supra pump installs in less than 30 minutes. Although I don't think it adds any hp. Just piece of mind.


let me know if I am wrong.

How streetable are the 850s all around(pri and sec)?

Would there be way to much gas for the primaries?
