After reading tons of threads here, I see the way to go is the greddy kit with the MM upgrade. How come the esmeril kit lacks popularity? I have read the threads and realize there is an esmeril representative on the board as well as some extensive build threads, but how come what apears to be a more efficient kit is less popular? Also more importantly, how much fabrication is required for each kit?

Thanks guys

esmeril was being questioned against the quality of the parts and the wastegate location both which they changed. Another thing is most people like to use the cobb which doesnt work well with that kit

the greddy set up is the oldest kit and lots of used one floating around. mm turbo not as common as the build times can be a bit long

and what do u mean fabrication, the fab that went into the kit or to install it, they are bolt ons. base greddy kit should have a bov and a niple welded in to the pipes but those are just fixes to the kit.

You obviously didn't read very much.

also look up the dyno of the diffrent kits overlaid, not sure how you came up with what is more efficient.

Well sorry, I did some searching and did look at some of your dynos. As far as being efficient, from what I could see, and correct me if I'm wrong, the average greddy kit users run around 7psi and pull around 300rwhp, while the esmeril kit runs 10+ psi and according to their site can produce as much as 400rwhp. I'll look for some more dynos in a second, again, I'm more interested in the esmeril kit. EDIT: If this thread https://www.rx8club.com/series-i-major-horsepower-upgrades-93/highest-horsepower-dynos-sc-turbo-nitrous-post-them-here-180037/ is not the place to look, then sorry for my mistake.

With fabrication I assumed it wasn't 100% bolt on because in an earlier post I was told to expect to be paying a good amount of money for fabrication of that turbo kit and was redirected to this subcategory to see how much. So back to my original question, is it 100% bolt on or will it require additional fabrication?

reno

Here I think this is a better way to ask my question, I know it's a little vague.

1) Do you have the Esmeril or the Greddy/MM kit and why did you pick that one?

2) Are the kits 100% bolt-on

3) What psi are you running

Thanks again

Biggest deciding factor between the greddy and a top mount is cost. If you are looking for a quality made top mount turbo system we have done several and can help you out.

The stock Greddy kit can be made into something pretty awesome with a little knowledge and perseverance . Both being in very short supply by most that fit the kit .

Correct for average on a stock kit.

Wrong. The average stock greddy with a high flow or no cat will put down 240HP. 300 can be made but upgrades are needed, starting with the turbo (different turbo or modified turbo)

reno

highway8 the 300whp I was referring to was a greddy with the MM upgrade, is that what you were talking about too?

btw highway8 your procharger build is very cool and turblown I have PM'd you

Good thread, I'm in.

How many modification are you talking about? Enough to be in the same price range as the SFR turbo?

Brettus

/\
Upgraded turbo - $1000
AEM intake - $300 ?
Accessport - $600 ? if you can get one
BOV
Boost controller

With stock greddy kit and AP you should be able to put down 260-270whp..... and maybe some wastegate actuator fiddling... and I'd say a BOV is mandatory for the turbo to last

burn89

plus the original price of the turbo.. so you are saying it's still about 2k under the SFR?

RotaryMachineRx

iTrader: (1)

Everything in my sig regarding turbo, AP and gauges ran me about $6000 (CAD)

burn89

That isn't bad, and you are pushing 260-270whp with your setup?

RotaryMachineRx

It's not installed yet... starting on friday then I still need to get my MM tune so probably won't hit a dyno till next spring when I complete my tune; plus the car will be parked for the winter

burn89

ahh sorry it's gonna take you that long to be able to test it.. gonna be about a year until i decide which turbo i'm gonna get and install it

RotaryMachineRx

iTrader: (1)

It all depends on how reliable the MM tunes will run if they are only partially complete and how bogged down he is... which right now I think he is pretty ridiculously busy... and I don't really wanna push my car until I have a solid tune. As for drivability it should be able to be driven with the base FI map and I should be able to start seeing some positive manifold pressure after the first calibration is recieved... but not going to waste money on a dyno for a half tuned car. If you plan on buying a turbo kit remember you need a tuning platform as well, you cant just slap it on out of the box and expect it to be reliable

reno

Thanks for all the information!

I know the ap is discontinued, that I guess that means I would be stuck with a microtech or interceptor right?

What system are you using to tune your engine? I really don't know of any reliable tuners in my area

RotaryMachineRx

iTrader: (1)

Yeah I was lucky enough to buy an AP before they were discontinued, you could try to find a used one... but that'll be tough... but if you arent planning to buy for a year MM will most likely have a new tuning platform by then. Or go with a kit with tuning platform included (not greddy emanage).

Do you guys think the price difference between the Greddy and the Esmeril kit could be an important factor. In terms of popularity I mean. Not that I know the prices of them becouse I dont have a renny, so I never really got into that, but I would assume Greddy would be considerably cheapper, thus more people would buy it regardless which is better ( we all know not everybody cares about the quality, they just care about their pockets) . I'm just bringing the price topic into discussion, so he does more research and you guys can elaborate with your opinnions.


I know Esmeril personally so I have to say it.... Esmeril is better.. haha

RXPLODE

I just got done installing my greddy kit, I have a cobb ap, rx7 store midpipe with high flow cat and a greddy se, recirc bov. I have to fix a leaky oil tee and ill be ready to rock once my tune is ready. I plan on doing a dyno mid next month. I've done the greddy fix #2.

I'm not even going to disagree with you... a few reasons I went with GReddy over Esmeril though.... I sent emails to Charles at BHR and Chris from Esmeril asking some questions about each kit and never ever did get a reply from Chris which led to me buying the GReddy kit form BHR. Second I did not want to deal with relocating my battery as I am doing the install myself and this is the first time I've done anything like this. Thirdly I wanted the use of the Cobb AP because it seemed like the more convienient route for tuning. Fourthly more people use the GReddy kit therefore more available research and support from other members.

Now with all that aside you have a valid point about the price difference looking alot cheaper for the GReddy; but when everything is said and done... to do the GReddy kit right the cost difference is not very much of a difference between the two kits. I spent around $6500 (CAD) to get everything (I believe) is needed to reliably run the GReddy kit (that's including BHR midpipe). Now I also think that the Esmeril kit would be a more mechanically sound kit; and what I mean by that is a better turbo and the GReddy Manifold is a known weak spot. ONLY because of the reasons mentioned above is why I personally went with GReddy over the Esmeril kit. But in all reality either kit is going to properly add the power you are looking for as long as you take the time to reasearch and do things right!

There's my two cents
