the car is a 83 mazda rx7 engine is a 91 j-spec turbo 2 motor transmission is stock stock turbo@10psi intake is a Weber 45mm DCOE non intercooled ignition is a locked distributor, 2 MSD 6 AL's , 2 blaster coils, MSD plug wires, NGK B10EV spark plugs lightened flywheel(steel) RPS turbo clutch the car runs on 91 pump gas see the video at www.rotaryshack.com/movies,, silver car see the dynosheet at www.rotaryshack.com/dynosheets silver car |
impressive.

the video is at www.Rotaryshack.com/movies
silver car this setup is very reliable and is the least inexpensive way to make your Mazda turbocharged with good results.if the car has good traction it should have no problems getting 12 second timeslips! I have alot of local guys with this setup that are pleased with the results |
ok, I am a little confused. Why does the dyno sheet say halltech - 25 lb boost?
|
Because you are looking at the wrong sheet.
Did you happen to have a wideband hooked up to it? I'd be interested in seeing the A/F ratios for that thing with no intercooler. |

680, why no intercooler?
|
Originally posted by Directfreak 680, why no intercooler? intercoolers are not manditory, just an option..the car runs great without it, remember , its a budget turbo kit! plus since there is no intercooler, or intercooler piping there is NO TURBO LAG AT ALL!! on low boost turbo systems intercoolers are not as important as on a high boost application |
How much does the "budget turbo kit" cost?
|
Hi Robert. Thanks for posting this and I'm a happy camper! We already phoned to do a few more stuff (non-motor wise) since I have so little time to do anything because of my work. I'm glad that the wheels looks good on that car too. Once I get more internet savvy, I'll try to post more on this board. I'll be down in that area in the next few weeks as I see on my books.
Andrew Leung :p: |
cost and avalablity of the low cost turbo kit??
for GOD sakes MAN MORE Details !!! lol randy |
I would like to know what carb bonnet you are using
|
Turbo Plenum (bonnet)

15x7 Panasports with 205 Khumos
I got them thru the parts trader |
That's pretty good numbers. Stock turbo, 10psi. I take it the engine porting and internals are all stock as well?
You could easily bump that number up with addition of an intercooler. I would only run without an intercooler with less than 8psi of boost. Plus adding one is that much more reliable. I'm sure you already know this (well, i KNOW you know this!) but I see you are talking just a "bolt on budget package" type of thing. Good work and good numbers, keep it up! ps - You know what would make that carb setup really sweet? See my username ;) |
Good job Robert. I knew you would make Andrew happy.;)

Hey, does that mean it's time for a...:grouphug:

680 quick question, how would you even begin to get it smogged here in Ca? also i would like to know how much that "budget" setup would run?
|
Im glad its all over and I don’t mind to put my name on the line again to keep the peace.
Rob, Congrats and here’s one for you…. :bigthumb: :beerchug: mel |
Good question, how much is the "budget" setup? And what all does it include. I have a buddy who wants to buy a car... I'd rather see him in a turboed 1st gen than an NA 300zx :D

wow impressive i would like to hear my car like that :D
|
Originally posted by 12aPwr 680 quick question, how would you even begin to get it smogged here in Ca? also i would like to know how much that "budget" setup would run? The setup probably could not be smog legal in CA.. I believe he would have to get all the components CARB legal to do that. But with enough cats it would probably pass the sniffer test. or you could always lean it out and not boost while on the rollers :) |
you would have to have the stock exhaust from the TII, along with the stock intake and ecu...
there is no way that it will be legal... just have to find someone that does not care about visuals. |
Originally posted by riffraff you would have to have the stock exhaust from the TII, along with the stock intake and ecu... there is no way that it will be legal... just have to find someone that does not care about visuals. This is on the stock 12A.. so they would not have to worry about emmissions from the later 13BT.. The law you are thinking is if they did a TII swap.. this is a turbo 12A.. But there will still be problems.. |
thanks for all the positive comments guys, it means alot to me!!!:) :eek: :eek: The system on andrews car is not smog legal, but then again i know CARB exempt guys in hondas that get harassed constantly!!! In my opinion, the police harass the honda guys , and usally the Mazda guys are left alone, around here anyways ...
The turbo kit on andrews car was built to his specific needs ..The car is totaly reliable @10 psi with no intercooler and can be daily driven with ease!! Yes it might make more power with an intercooler , but at approx. 300 h/p at the flywheel , and a tight budget the car is pleanty fast! a couple of forum members were asking for turbo kit pricing,,,,, well YOU make the price! each person has different goals (type of racing, h/p goal, budget$$$)so each turbo kit is different .. thanks again!! |
Im really happy that Andrews car is going. I never put two and two together until just now, but is this the car that had the supposed "cracked turbo mani and the oil leaking turbo" and all that shit right? I knew that Robert sounded like a good guy caught up in a bad mess when I was reading his posts. Im glad he made right on a poor situation. I talked to him on the phone recently, and he sounds like a good guy. Id be happy doing business with him :).
~T.J. PS - I dont wanna sound like Im taking sides here...As in, Im not saying the car wasnt actually broken, and Im not saying that it was Roberts fault. Im just glad the end result is that everyone is happy :). |
I haven't seen my car for awhile....it isn't a big deal really as this vehicle is not a priority to me really. I guess now I'm abit anxious for summertime. I do have to say that some of the feet dragging is sorta my fault...solely because of my priorities is definitely not on my Rx7. But I'm planning to be down in the SoCal area next week on Friday. So I'll look at the car.
I do have to say that I feel very blessed to have nice people around me...including MikeB (Mazspeed) and Robert as both are looking out for my best interest. I am dissapointed at Jeff (MazdaRacing) at enhancing inconsistencies to the equation of my dealings with my car. Mike is a good buddy to me (and lives close to me as well) and Robert has been working with me. Maybe both will settle it..but they are adults and they can figure that out without anyone's help. I generally don't even frequent any forum and the such as my time is very limited, but I was pretty much forced to participate to post as many wanted to know who or what or if I really exist...kinda. I didn't read this forum until the beginning of this week anyways. |
I think Robert @ RotaryShack is a very nice, helpful guy! He clearly knows his shit about Rotary's. I have talked to him several times on the phone and he is very honest and knowledeable. I think all the (missunderstandings) from the past, are from the past. I recently ordered a carb from him and everything is running smoothly. I will definately order from him again.. So Robert, get that turbo set-up ready for me!!!

My issues where with Jeff s well, he never had returned my $$$, or my phone calls. His web site sucks ars too...... Just like him.......
Robert and I are currently working on a project together, wait till you all see what he comes out with next. Andrew, I spoke to you a long time ago about possibly buying your old carb, I live here in Dublin, you may not remember our couple of conversasions, but when you get your car up, we should go for a ride...... I am currently restoring my 82, I can not wait. Peace out all, Chris |
Sure Chris, Robert told me alittle bit. I also have a home in Brentwood so it is close. I'll try to swing by and chat with you.
You just need to give me your info again so just email be at firstgen82@yahoo.com and probably hook up by months end. Thanks Andrew |
Ditto??
