450-500WHP setup?

Would this setup be able to do 450-500 WHP pretty easily and reliably on some what low boost (below 20lb)?

REA dolphin tail exhaust
Apexi Power FC or haltech
Nippondenso Fuel Pump(aka supra pump) with ID 2200cc injectors (Secondary)
ID 850cc Injectors(Primary) (FFE setup)
RX7 store v mount intercooler
T04z Turbo
HKS Twin Power Ignition
Last but not least a LARGE street port (possibly bridge port)

Would it be beneficial to get water meth as well?

Water/meth is always advantageous.

If you run a full 3" (no cats) setup with a GOOD (not some shitty knock-off brand) single turbo kit, than you should def be able to hit 450whp.

Keep in mind though... JUST focusing on a power number is bound to leave you at a disadvantage. Getting a FULL support system able to reliably run that power level is vastly different from just brushing up against the number..

My suggestion: Scrap the PFC in favor of a PS1000/2000, get FFE rails with the ID injectors and their better trigger kit. Address your coils (not just a band-aid like the Twin Power) and make sure your rails/lines are up to snuff. An exhaust system is only as free flowing as it's most restrictive point. HUGE porting isn't necessary for peak power (it can actually negatively effect your USABLE power).

Make sure your Fueling is good. Make sure your intake temps are good. Minimize your EGTs and EMAP. Make sure the REST of your car is up to snuff.... Enjoy your car and realize that you DON'T need to make a gazillion whp to have an enjoyable car.

Anybody can make those power figures, once. Wouldn't you rather be able to make it every day without worry?

I wouldn't go with a v-mount kit. Also, look into your tuner before hand to make sure you have someone that can advise you on power.

I more or less used the RX7store stage 3+ kit and changed out some of the parts. So basically change around the fuel rails and don't go for a extremely large port?
I'm building more or less a track car that i can still drive around on the weekends, i DD a bagged VW GTI.

I'm using numbers similar to a REA super G or a R magic car. (hopefully)

Why do you advise against a VMIC? That, frankly, seems very silly and poorly informed to me.

Though I DEFINITELY agree that the tuner matters as much (if not more) than anything!!

I have a personal aversion to anything that RX7Store makes, but that is just me. I would look around at some of the other options out there as you'll be able to get the same (likely much better) quality items elsewhere for less.

I used it more as a guideline then anything else. I'll obviously shop around for the best price. Though do you have any reasons why you avoid their stuff?

My personal experience, and observations, is that they sell ebay brand items as their own. Fitment may, or may not, work. Quality may, or may not, be up to par. Items listed as in stock may, or may not, be available. etc., etc., etc.

If you search around you'll find people that swear by that shop, but you'll also find threads (if they haven't been deleted or modified) where kits they have sold just flat out don't fit in the allocated space.

I have a solid disdain for spending name brand money on items that I thought were reputable parts, only to receive chinese knock-offs MONTHS after getting charged for "in stock" items.

WI, that turbo and the best tune you can get should be enough easily...I don't recommend meth because it can wear internal soft parts but it does work very well and many people swear by it. But water is just as good and is more than capable of reaching that power level, even more.

Should I just piece together the kit then? I'm thinking more garret > hks since the garret is half the price and I've heard nothing but great things about them.

My post was worse than this before I edited it. I've seen their v-mount kit in person and was less than impressed. They indeed use a lot of cheap parts in everything they sell. No matter if it's a turbo kit, inter-cooler setup, ext. Profit seems to be the only priority.

Also avoid rotary works. It's owned by CX Racing so you're getting the same exact stuff...

The stuff I sell fits. How do I know, because I have installed it a million times. If something has not fit we have made changes so they fit, but that is rare. Most of the stuff I sell is not made by us and is name brand stuff so fitment shouldn't be an issue.

To answer the OP question. We have done that setup many times producing anywhere between 420-520 RWHP depending on boost and engine port. If you are going for 17-20lbs of boost you will need more pump than what the supra pump will offer. Add a bosch 044 external with the supra and it will be good.

If you're not wanting to fab your own kit than you might like the Rotary Extreme kit. I don't personally have it, but I think I remember hearing that they are pretty nice and it's within your stated price range/expectancy.

Rotary Extreme - 3rd Gen RX-7 (FD3S) Products

I'm sure others can chime in on whether they are quality or not.

Interesting. I use a Greddy style intercooler that is modified and a Original Koyo radiator in the vmount kit. I made a kit that is affordable for those that want one that isn't $3000.
Our turbo kit uses Garrett Turbos, Tial wastegates and stainless downpipe and manifold. I keep the price down on these kits by going with an off the shelf manifold from Japan. So far no real issues with the manifold. If I wanted to make an expensive manifold I could but whats the point. Profit wise I make about $300 on a kit, so as much as you think profit margins are %50 on this stuff, they aren't.

Just like your GTX35r kits fit just fine?

What is the name brand of the IC used in your vmic?

Greddy style says to me that it's some cheap knock-off brand. And, no offense, but the welding on your modified koyo looks mediocre at best. I'm not a welder but even I can how that bead looks less than even.

Just because the welding was done in Japan doesn't mean it's quality. If anything the manifold is on place I would NOT skimp. Again, who the (un-named) manufacturer of these asian manifolds?

Megan, XS Power, CX Racing, Rotora, etc., are all name brands too, they just aren't really good ones (and I've received "RX7Store" items that were from them).

When the GTX35R came out we had a couple of customers with fitment issues on our current manifold. They were fixed at no additional cost and we do a modification now on any kit so it doesn't happen again. Other wise of the 75 kits we have sold 2-3 of them have ever had issues.

Yeah I said Greddy style ( probably similar to the ones on ebay). You cant figure that out from the price of the kit? As I said we offer one that isnt $3000. Whats the point when our Vmount works the same for a fraction of the price. Whether you like the look of it that is all personal opinion. All of the other cheaper vmounts on the market use ebay style cores also. Does that mean they dont work?
I have tuned many cars that run ebay intercoolers and never any issues with heat.

There is no name brand on our manifolds. I get them from a supplier overseas. If they were junk I wouldnt sell them as Its not worth the money and hassle to replace bad manifolds.

You seem to equate high price with quality. Fact is you can get stuff that works as well as the overpriced stuff for a fraction of the price.

I can build you a kit in a couple weeks. The biggest wait would be on Garrett, I don't stock them as I prefer Borg Warner. We supply a couple shops with their turbos and turbo kits. PM me if interested I'm not going to hunt you down.

well i personally HAD the rx7store vmount kit and I say had because it was sub par. i did keep my expectations reasonable to low given the price of the kit and I was still disappointed in the quality. the welds werent the best but there were no leaks. i can honestly say the biggest bummer to me though the was the obvious lack of caring on rx7stores part.

the radiator drain was neglected to be moved to the bottom which is a pain because fluid goes all over the place when you need to drain it. his site does show it in the top position now though, it didnt when i bought mine. the brackets to mount the radiator are crude at best. the welds on mine looked no where near as nice as the ones that are currently pictured on his site.

when i mentioned my concerns, he told me to remove the lower hose, which there really isnt one. unfortunately the only way to fully drain the radiator is to remove it from the car. on the overall quality issue, he made it seem like his products are on par with other higher priced manufactuers like he seems to do in every thread where something is brought up whether it be quality or poor customer service or never responding to phone calls or not getting your parts on time or...the guy is just full of excuses, he never even offered to fix or offer any help or insight in any form. needless to say i will never give him another penny. it does make you wonder though, if his products and business model is as good as he says, why so many threads or posts like this one compared to other companies? something to consider.

I am going to be honest with you man, unless you are willing to spend $10,000 or more on a good 500HP build dont waste your time..

a well built single turbo kit will run you $4000
a real V mount kit will run you $3000
a real well built fuel system will cost you $2000
built engine $5000
you see where i am going with this? any real enthusiast here who has been there done that will tell you the facts!!! i am not trying discourage you i am just being realistic and saving you time and money!!

In response to this. We have never had the radiator drain on the bottom. We left it in the same spot as koyo put it. I admit not the best location for draining it. We remove one of the upper hoses and let it drain as much as we can and then just pull the radiator out and dump the rest. Removing the radiator takes about 5 minutes.

I have never once said our setup is as nice as the $3k setups on the market. I have said they work the same and the cooling is similar for a fraction of the price, which it true.

I could build $3k vmounts and $4k turbo kits that look like God handcrafted them but the fact is 99% of RX-7 owners don't buy that stuff. The RX-7 market is a dying breed and most owners buy the cheaper stuff that works.

Well said, I only made the mistake of ordering from them once. Unfortunately it was an $8,000 mistake that resulted in knock-off items, the WRONG items, and months of lies before finally receiving what they sold me.

Why would you even do that? If you're going to cut up a radiator to make it fit an application that it's not meant for than why not frankenstein that **** correctly...

Merchants and self-proclaimed "professionals" who don't give a **** about making a good product need to be run out of business imo, not only are they hurting the community but they're giving the rest of the merchants a bad name.

That is a relatively poor breakdown i would say.
Being in the process of a 500whp build as well, I would say hope for 12-13k, plan for 18-20.
I'm in about 15k at the moment and i would say have 8k to go BEFORE even touching a dyno. No one said it was cheap...


Edit.. actually, maybe the break down isn't so bad. Just sort of hits the bigger stuff. What everyone forgets is how fast the small things add up..
