Not sure if Im gonna do it on a T78, T88, or a T04E kit, but right now Im conserned about fuel. I'm planning on going with a dual walbro fuel pump, 850cc primaries, and 1680cc secondaries. My question is - will I need to upgrade the stock fuel lines to something like -8 or -10an or will the stock line flow enough?

This means Im probably gonna run boost somewhere in the 25lb range

 

A T04E won't come close to flowing 600 wheel just for reference.

 

Yeah no kidding. I'm pushing almost as much hp on the stock twins as most people with the t04 kit, lol. 600hp in an RX7 is really too much and I doubt it would hold up very long. A good buddy of mine was pushing well over 500 in his FD and he hated to drive it. He eventually sold it and said he will own another FD someday but will never go that crazy on power again.

I think you'd want more than two 1600's. Possibly tap a few into your intake elbow/UIM or buy that GroundZero LIM.

 

 

you'll def need a hondata.

 

600wph + FD = Death

 

I am still alive.

 

20B don't count.

I couldn't even fathom something like your car.

 

You are either brave, or really crazy. Ive been in a FD with 530whp, and that thing was insane. Im cool with 300-350whp

P.S. Whats with the big dip on the dynosheet?

 

how often do you drive the car with that kind of power? one of my concerns with that amount of hp would be i couldnt daily drive it (during the summer months) anymore.

 

yea, it could be a daily driver, depend on how often you use that kind of power. I can go ahead and tell you now that you arnt going to make that kinda power yet, unless you have the money to have someone else do a 20b for you. By the time you have gone single, and pop a few engines at low boost, you would'nt dare think of 25lbs!.

 

thats a absolute must have

 

The dyno run had started the recording process in 3rd gear, then shifted to 4th, then went WOT. 4th gear dyno is ZIIIIIIIP done (very fast).

 

My car is a weekend warrior. You could daily drive it, but why? It isn't very comfortable, it is loud, doesn't get the best gas mpg rating, and allows weirdo's to possible hurt the car. The horsepower is realitive to boost and your foot. With foot control, anything can be reliable. At 13.5 psi of boost, it is very reliable; but again, it is just a weekend toy.

 

its totally possible, just have enough money and its easy.

 

Exactly. That's how Mazda won LeMans in 1991. Yes, good engineering, yadda yadda... but also a boatload of cash. Mazda never won before. When they learned that rotaries would be outlawed starting in 1992, they decided to go all-out on the last chance they'd get. And they won. Coincidence? Probably not :-).

Take care,
Shad

 

a 20b with 600 hp is a monster, but at least the power delivery is not the ultra peaky whiplash type powerband you would get with a 13b, which is useless anywhere but the dragstrip

 

good luck

 

Im already bored of 295whp. I need something faster. Something Im gonna kill myself in. So seriously, whats wrong with 600whp in a 13b? I know it can be done. Thats not an issue. And I'm not just gonna throw a turbo kit on there and shoot for 25lbs off the bat. Thats asking for trouble. But its an achievable goal. Why not go for it? I mean, hell, this isnt a supercharger we're talking about. Im not a lead foot, and as long as I stay out of boost I dont see how its not streetable.

I'll work my way up to 600whp, and probably whatever hp number I hit that I **** bricks at and almost kill myself is the one I'll stop at. But lets say 600whp is my goal. Should I upgrade my primaries too? Is 850 and 1680 not enough? And nobody answered my original question - will I have to upgrade my fuel lines or will the stock ones flow enough?

 

high hp FD = have fun shitting money

dont argue, its true

 

Thats true for any non-stock FD.

 

 

That's what I would think. As long as you're easy on the throttle, and you keep your boost low (boost controller and/or diff setting via ECU), I don't see why it wouldn't be streetable. Having 600rwhp ALL THE TIME sounds like a bad idea though. Mash the peddle by accident once, and you'll be going sideways...

 

Man, mash the peddle in my t78 with 430 at the wheels and you'll be going sideways to. With any high Hp Fd, foot control and accuracy is your number 1 threat.

 

I'm expecting about 600hp or a little more out of mine if I ever call it "done". You're not going to do it on a single t04E. You'll need two : P. Seriously there's a lot to it and a lot of money involved in doing things right. Realistically I'll be braking some driveline parts after I do get everything dialed in and turned up. You'll also have to be running something like C16 if you going to get near 600 and really should anytime past 450.
