I am currently swapping my 89 Gt from a Ysi to a Precision 101 turbo. Its a 427 windsor, Victor Jr heads, 642,662 solid roller, Super Victor intake with a 850 CSU carb.

I traded the Ysi off for the 101 and a Precision 66mm wastegate. Also traded the carb off for a Super Victor EFI intake, Wilson elbow, and 105mm throttle body.

I have a few questions I need help with...

Injector sizing, Fuel pump and regulator, gas or E85, and engine management? What is best to go with? Im thinking the Holley EFI. Any help!!!

Yeah my cam and convertor will probably be changed but I want to try them first and see how they do. I have a 3800 spragless convertor in it now with a th400 tranny. After I pulled the blower off, it would only stall around 2K on the brake.

I would 100 percent recomend a whole a1000 fuel system from pump to rails.. I have heard good things about holley system. But would also recommend the fast classic system..With the fuel system u can run either.. And with the fast u can adjust tune for e85 or 93 octane.. Injectors im gonna leave to the pro cause iys gonna matter for street or strip use..

FAST for the computer, and a magnafuel pump with BIG injectors. Seen it work on many different setups. With that setup on good gas (e85 or race gas) itll be a hell of a car in the quarter.

For the converter it is all trial and error. See where it comes up on the trans brake, and see how it does on the track. My friends car would only hit 135 on the dyno but trapped 151 at the track because of how loose it is.

A1000 sucks,that pump is garbage,do MagnaFuel all the way,like the pro-tuner 750,do a search on the A1000 it will fail you

I mean im not sayin theres not better.. But for the money in the build its kinda hard to beat.. And yes u can find more complaints about them over what u stated but u also got to factor in the amount of people running this system.. Mustang86 ur in my back yard.. Car be up and running in 2 weeks or so, if u would like to compare...

Right now I have an Aeromotive Eliminator pump on the car with a -10 feed and -8 return but its set up for the carb still. I keep looking at the Magnafuel 750 or the Weldon 2035.

I would consider the bs3 for the management. Most of the guys running drag week use it if they're running an injected setup. What did your previous setup produce on the dyno? I would use that as a starting point for the injector selection then pick one that will support 25% more power. As for fuel delivery you can pick either pump. MOST of the guys on drag week run the magnafuel, but the other ones run the aeromotive eliminator setup. You have to make that choice on your own. I would recommend you decide before how this setup is gonna spend most of it's time whether it be street or strip for your fuel selection. Remember not all e85 is e85 i've seen it as low as e62 here in kc. So building your setup for it may not give you the results you expect. EIther pump gas or race gas. If you really want e85 get it in a barrel.

Kinda on topic here but how much do you think a Pro Tuner 625 pump will support on a FI engine? (its the pump I have but not installed) I was thinking it should handle 700-900WHP on pump gas, less on E-85 I know.

On the engine dyno with the Ysi it made 1270hp/1130tq. Id like this one to make around 1200 to the tire. I think Im going to stick woth gas for now as well. I want to be able to drive it on the street on lower setting. And I have the Aeromotive Eliminator on it now but I think they max out around 1000 hp.

So you're going to need to upgrade your fuel system what size lines have you got now? You're blow thru carb now correct? Also it seems like you're trying to pick up around another 200 to the tire so are you going the air to water route? I hope so cause I'm pretty certain air 2 air is out of the question now. Gonna be a pretty hairy setup if it were me I'd call Kurgan and get some more in depth answers.

Right now I've got a -10 supply and an -8 return with the eliminators pump. I am switching to the super victor efi so I will need somewhat of a new fuel system anyway.

In my opinion e85 sucks.... You need way more fuel to make the power.... We generally like to run 2 or 3 sizes larger of a injector to make the power... This also means bigger pump line so on... But at the same time e85 or I think Vp is now calling there barrel C85? Is a great fuel to make good power... Your luckily in a position to make the call where most guys are trying to convert a car that's already built for gas.

As far as management I would say that a BS3 or FAST is the way to go! Both are awesome setups!

Yeah Im pretty much completely starting over so I have a few options. I think Ill just stick to gas. I know alot of people I have been talking to say the new Holley stuff is nice. Just need to get the bugs worked out. Im still picking up parts as I go so we'll see how it turns out!

Before.

your going to need some massive pump and injectors for 1200 rwhp on e85. Maybe in the range where the billet atomizers are giving you some real gain.

I put 160lbs and I never plan on seeing over 800rwhp on my e85 turbo cobra
