i am looking to get the best turbo kit that i can, price isnt much of a concern right now, but i am looking to get 500HP+ from it. i am also thinking of going with a twin setup for more power. Does anyone have any recommendations on a specific kit?

 

i think single is better if you want a lot of power on ebay this fool is selling a single kit for like 2400 without intercoller or something check out ebay for rx-7 turbo

 

ok ill check it out.
you say single has more power than twin? i dont understand that: if you had one 500HP turbo against a twin with the same power in each turbo (two 500 HP turbos), then wouldnt the twin win?

also i want this to be street legal. i looked at HKS's site and all of their turbo kits say (OFF-ROAD USE ONLY).

 

street legal
what do u mean by that ?
pass smog ? u better stay with stock

 

im not exactly sure what it means, but if you go to HKS's site, www.hksusa.com, and look up the turbo kits that they have for FDs then you will see (OFF-ROAD USE ONLY), that y i said "street legal"

 

single won't be street legal, only stockers. If you want to go fast there's no way to stay street legal, or I haven't found a way.

 

Depending on where the "Somewhere" you are from, FDs become not street legal pretty quickly in the upgrading process. I don't think any single will allow you to pass any emmissions tests and will not pass a visual. I think the apexi rx6 allows you to keep the air pump but they have been discontinued. I really don't know what most people on here do to pass inspections but what I do is just pay 100 bucks a year to a shady mechanic and he hands over an inspection sticker. If you go that route it doesn't matter what you do to the car

 

so your saying everyone on here who has a turbo, single or twin, are not street legal? they cant drive them on the street?

my question still stands: if you had one 500HP turbo against a twin with the same power in each turbo (two 500 HP turbos), then wouldnt the twin win?

 

Power-wise, the twin-turbo setup will win, but I'm quite sure it will be more laggy than the former.

On the FD, stock twin turbos are completely legal, and on the plus side, they can supply the engine with, at the most IMO, 360 rwhp. Anyway, just because it's not legal doesn't mean you can't drive it on the street.

Yes, in certain, if not most, instances, single turbos are illegal, perhaps moreso in ****-retentive states such as California.

BTW, why are you shooting for 500 "legal" horsepower?

 

ohh ok
im going for 500 because its a high number, and in this case high numbers are good , but i am going for legal becuase i dont want this to be a straight up track car, i want to be able to drive it on the streets without any problems.

 

So that he has enough power to move after all the junk he wants to load the vehicle up with.

 

haha!! yes that is one reason...but all of that stuff about the sound system is just speculation at this point.

 

Damn. I don't know how you're going to pull that off. Good luck though.

 

all they are doing on that thread is just picking at every single little thing that i say. it was just supposed to be a simple thread to see if it would work. they just had to make it difficult

 

Tis' the nature of the beast, internet, young grasshopper

 

basically your question shows that you should some reading and searching. and thats why people are picking on you.

if you want 500+hp you'll need a laggy turbo, a good tuner, and be able to afford your engine not lasting as long as it normally would.

check this out http://www.kgparts.com/R85.htm
460hp@14psi. and then 620hp@25psi

either way it sounds like people are just throwing ridiculous numbers around. do you know how fast 500hp in an fd is? or even 400? and i guess the 40r might be able to have that power at pretty high boost...?

 

no offence, but WTF?!?!

 

yeah i know all of thses sound rediculous, but its only becuase im planning everything before i spend any money because of the cost issues. if i dont plan this and just go out and buy stuff and then find something better and replace the old one it will get a lot more costly then it would if i planned everything like i am now.

 

I agree with that route and am doing the same myself, but its a long process. What I meant earlier is that people are going to be mean and nitpick everything you say if you make some stupid posts, no offence of coarse because we've all had them.

and people are always going to say search, which is a good idea, but sometimes doesnt yield result, then its good to ask.

and no offence to anyone on here, not saying nobody knows anything, but its always a better idea to find out which members have their knowledge and information from real experience and/or facts, rather then hear-say, and listen to them or pm them and get advice.

 

ohhhh...ok. i know its a long process, ive been working on mine for many many months now. ive been researching, asking, going from one place to another asking salesmen, RX7 owners, other racers....ive been doing almost everything that anyone could do if you are going the route i am. it can get pretty difficult, but in the end it all pays off.

 

It doesnt work that way, you dont slap a "500hp" turbo on a car and instantly have 500 HP, so the one with twin "500hp" turbos WONT have 1000HP. That number is what the manufacter got out of the turbo on a certain set-up. If you throw that turbo on your car (whenever you get it) it'll be a 0HP turbo' because your ***** gonna blow.

 

I hope I speak for all when I say ..... YOUR AN IDIOT!! If u know that little about turbos than theres no way u know about rotaries, so if i were u id read up b4 I even started my car.

 

sorry to answere your question.... NO FOOL

 

You are quite niave if you have done any amount of research.

To achieve 500 horsepower here is the bottom line.

Around 20 thousand in parts and who knows what in labor.

You will go single because going twin for 500 horse power would be too complex and there is not much aftermarket demad for it. Hence, why you have not done your research about buying a kit. You automatically think, very niavely, that 2 turbos are better. The fastest RX7s in the world only have one.

You will have to either run race gas to prevent detonation or do a methanol injection setup to lower you knock levels to achieve the boost for that power.

You will need a huge single and you will have HUGE lag. It will not be reliable and you will not pass emisions. The car will not be illegal at this point in the way you are thinking, again very niavely. You will have a legit vin number and only be hindered, depending upon you state laws, by your exhaust gas. I pass by having a few mechanic buddies.

Do some research and you will be on your way to finding out that you are in over your head.

 

satoacs, I think you should read this book.
