As for the fuel system from Rx7store.net

Its almost complete(Ultimate fuel system), very easy to install and not overpriced.
If you are only going with the extreme (Just secondary Rail) you should be more than fine
Thanks, but I've got myself the cj-motorsport fuel system. Not saying the rx7store fuel system isnt good, but the cj motorsport is even better. And my gf bought it for my for my up coming birthday (july 5th) =)

I am such a lucky guy!

Too funny. Saying one kit is better than another because of one race between two different setups is as stupid as the X turbo versus Y turbo threads. Two different motors, two different tunes, with two different setups yet somehow none of that matters, only what "kit" was on the car Silly me, that makes perfect sense.


Please give me your noticeable benefits to dual WG design. Not theory, solid numbers. My guess there wont be any. Dual WG are good for larger valve to diaphragm ratios and can help moderate lower boost levels better than say one larger gate. They are hard to setup properly to see this benefit however and are completely useless practically for this app. They certainly can outflow one gate if balanced correctly but again.... are you trying to divert a massive amount of air from the turbine? They wont respond as quickly as a well thought out single gate either. Been there done that. Sure it's cool to say I have dual WG's but other than that you just adding weight and complexity for complexities sake nine times out of ten.

As for spools faster, where both kits run on the same motor? Same tune/timing etc.? Same IC? Apples to apples a non BB BW unit will not out spool a GT series BB turbo of the same size period done it, tested it, numerous times on various sized turbo's on diesel apps. Even did all the "oil pressure" and "oil type" tricks BW reps claim make the difference, doesn't happen. Some BW units made power sooner, were talking a few hp difference in the curve, like 5-7hp but were not more responsive or even close and there is a difference. That also is more likely attributed to the edge on compressor wheel design that goes to BW.

Cheaper, eh... you may have me there, not too worried about it though other kits are cheaper yet still I get more and more track guys coming or switching daily.

One other thing to note Rich is running the older 500R the new ones are improved with higher flowing turbine wheels.


Keep in mind this is nothing personal or in no way a attack nor should it be seen as such. Just as I would assume you wouldn't say your post was a personal attack on me or A-spec, Just making sure things are clarified.

Well said Zero R. Just when i think i know something someone else has another opinion and i start to question my thinking and before long im lost again.
But with the setup in my fd now it just keeps going better and smother. Thank God for getting the right help and advice ,and i see too many guys on her jumping all over the place and breaking **** all to often! I think ive learned who to listen to and who not to plus every build is going to respond differently than an other.
My thanks go out to the guys that help out and have paid there dues!

Steve (pluto) can answer it..he's dynoed multiple cars and can vouch for the dual wastegate kit spooling faster. I'm sure he's got dyno numbers with stage 3 ports.

You shouldn't need the xcessive oil pan and the garfinkle oil pan brace. I would think either or. Both would I think be over kill. My buddies and I haven't had many problems after install just the brace. Or just the pan. Can't remember if we tried both. Pretty sure we haven't. Which ever you keep, you can always sell the other here on the forums.

Aiite Thank you for your input.

I havent bought the pan brace or the oil pan. But if that's the case, I shall just get the Xcessive Pan instead.

that Xsessive oil pan i hear has no input for a dip stick? it sits much lower than the stock pan from what i recall, if its going to see quite a bit of street time, i wouldn't put it on

nice list though, going to compare it to mine, everyone seems to be going 500R, might have to call a-spec up and change my gt35r order to that...

Decided to step down for the turbo. Instead of 500R, i can get a GT35 for much cheaper and hit my goal 400-450hp. So that can save myself 1.2k for an exedy twin disc

where are all the savings coming from? the kit is only 300 more? going to run a less extreme fuel setup?

i think it has been said earlier but make sure you get the ceramic coat option from a-spec, it is like 300+ dollars but it's worth it, if you go the CC route, you don't have that MUCH of a need to run the turbo blanket/shields/fiberglass wrap and can always do it later on down the road. coating the parts down the road is a major pain

i'm also looking into the exedy twin disc, just not sure if i want to dish out the extra cash for the carbon-D twin disc model that'll set me back 2k...

If you plan to run 15-20 psi, the 35R is probably the better bet. 20-25 psi, the 500R is where it's at

......which means I should probably switch to a 35R, b/c my dumb *** isn't running more than 20 psi

Why do an elimination pulley. Pull the air pump, throw it in the trash, and get a shorter belt. That's how many of them I,ve seen have been done. With the oil pan, we,ve had a lot of great reaction, no oil leaks, from just the oil pan brace. Several places sell it, most of them come with all the hardware as well.

My conversion is coming along at a steady, albeit slow, pace. I've completed most of the interior pieces, pulled the motor and broke it down, started cleaning, and moved to doing under car cleaning. One day it'll be done.

Oh and good idea with this thread, you can get a lot of good info fromsome of these guys, as well as a lot of the heads up, before something gets really costly.

That's exactly what I've been planning to do. Make sure I dont do anything stupid and get alot of heads up from these guy.

For sure I will have my parts coated. But not from A-Spec, I can get it elsewhere for less than half the price they charge me.

Also, Jason at RX7store.net seems to be very nice and easy to deal with and willing to negotiate things around for me. Really good business person =)

Hopefully my thread can help me and many others that are or will be doing what I am doing to be useful in the future =)

Much thanks all.

Just to share my experiences:
I am in the process of going single turbo. I have spoken to Steve about the single vs. dual wastegate issue and he clearly stated the dual has better boost control and is worth a minimum of 20 rwhp. The downside was that it is very difficult to dump back into the downpipe...so I went single wastegate. Also, I purchased the CJ motorsports fuel kit b/c just liked the craftmanship and it included everythingneeded to install. I purchased 4 1680's and 2 750 high imp injectors from KG. He was nice to deal with as well.

Overall- I really liked the quality that Aspec's kit shows in pics, but I never really could get solid dyno numbers from a "non-customer" for any of his setups. I think his kits are very well thought out quality wise. There is a guy that posts ALL OVER the forum and he hasn't posted any numbers for his ASPEC kit. That makes me question real-world HP ratings. All I read is how some kits are 500 hp turbos and they never make 500 hp.
I went with the GR67, which is basically a t04R with some minor mods because through theyears they have always made the HP I expected from a single setup.

On a personal note- I can't believe the amount of **** you remove to go single. I jave already spent over 6000 just to convert and I am still not finished.

Note to EZ- Don't go pissing away 1500 dollars on an
Exedy dual clutch unless you plan on making much more power, for a 35R, it isn't really necessary.

John

Hey John, thank you for the input. I really am appreciated.

Many others have told me to get a dual disc, thank God you came in and tell me that it is NOT necessary for a dual clutch =) Now I can probably spend that 1500 in suspension upgrades instead.

Thanks

Btw, I do think you made a sound decision with your turbo kit, there are many ways to skin a cat and the GR67 is definitely a solid choice
