I want to turbo my ka24 but dont wanna upgrade my fuel system so here's what i thought i would do.
Setup a turbo to run around 4psi with out an intercooler, cause i here that anything under 8psi is moderatly safe to run w/o one.

Then setup an alcohol injection system to run off a toggle switch similar to a nitrous system that activates at full throttle to run a alcohol injector and an extra fuel injector that will mix in right after the throttle body, while at the same time boost the pressure of the turbo to around 8 or 10psi.

The alcohol would serve as an intercooler by cooling the intake charge and the extra fuel injector would help supplement the extra demand for fuel.

My questions are:

1: would it be safe to run my car with the stock fuel system at 4psi?
2: can an alky injector system be modded and tuned to run both an alcohol injector and a fuel injector?
3: would my stock fuel pump handel the extra demand of a 5th injector?
4: will any of this work?

 

alcohol will corrode your cylender walls.

 

no it wont

 

four letters
SAFC
buy it
You dont absolutely need an intercooler, and the changing boost pressures is pointless. All that ghetto fabbing you want to do is gonna mess things up more than buying the right parts will. Also, whats the difference in turning up the boost when you wont be boosting that high under low throttle. I think you should read on KA-T.org.

 

bro

you don't have to change the entire fuel system.

120 bucks sr 370cc injectors
100 bucks walbro 255
125 bucks safc and your done and you can run around 8-10 psi with conservative timing

bro im all about saving money but you are cutting the corners to close. FMIC kits are to cheap now not to run one bro....

once again, i built my turbo kit for 800 bucks and went from 15.8 to 13.7 at only 6psi

 

Hey biggamehit, ive heard that you dont even need to upgrade the fuel pump if youre running 7-8 psi. Isnt the KA pump the same as the SR?

 

i beg to differ and as soon as i find the proof i'll link it.

i tried a water/alk. mixture about 2 years ago and it worked well. i did some research and ran into some discouraging info.

sure you can goggle it and get a dozen people telling you that it won't hurt your engine. but that same group of people are also trying to sell you a product. so of course they won't tell you that there products are can harm your engine.

 

na the 255 pump flows more fuel than the oem KA pump*. the FPR is the same however which is why you don't need an ADJ. FPR right away until you get around 15 psi and then you would want an rising rate FPR.

* ill get numbers

 

Yo Biggame show us some more snaps of ur sick-*** Turbo setup your currently rolling with so crazy antics get a good idea of cost-effective boostage.

 

lol man its nothing sick about it, its very basic all the things that must be right are right, ill post pics after i install the holset and clean all that damn oil out of my engine bay
