I've read alot of hybrid posts for the past while. But keeping the stock ECU and TMIC is my goal if I was to be using a TII engine. I just 'pondering' right now and getting ideas.

With the BNR stage 1 i'd love to get around 270hp to the wheels with the TMIC and stock ECU. So would you guys think this could work with bigger secondary injectors and say an rtek? This is a cost-effective upgrade of course (welcome to the second gen forum) and once again, im just getting ideas.

300RWHP on the TMIC is, well, what I've been told, impossible. There are a few members here running 275 though with no detonation retarding devices (water, methanol etc injection).

Really what im looking for is a plug and play solution here, and I know **** all about tuning. I'd love to just bolt these items on and drive the car.

Is this possible?

recommend something that is, or change what I have, input please

negative/positive posts towards this setup appreciate.

thank you.

 

I would definately say ATLEAST get an ARC(?) Upgraded top mount. Optimal would be an FMIC which in reality isn't that much work. If you're dedicated about working on your car the install could take a day or two at the most. If you absolutely must keep the stock ECU you should try that Rtek and fuel upgrades. You probably also want to keep a fuel controller in mind.

 

RTEK/pump/injectors will work ok, you'll be able to get away with the stock topmount, though they heatsoke so badly you'll have to take it easy if you let it sit and then go beat on it.

 

Thats what I thought, thank you for the confirmation.

However, to achieve that HP with those mods im guessing I'll also need a walkbro instead of the TII stock pump huh? If I get the walbro im also guessing that fuel pressure will be to high with the stock fpr. Im also guessing that a marrin fpr will mount on the stock rail, but it will not fit when the rail is seated with the injectors?

thx

 

Wankel7 runs a walbro with the stock reg, dunno what problems you've heard of?

 

I wasn't aware there was a TMIC upgrade available for our cars.
Does anyone else know anything about this?

 

with the tmic your first dyno pull might be 275 at 15psi... but then 2nd pull will show a loss because of heat soak.

i did 247 at 11psi then 235 2nd pull... 3rd pull was 229.

i wish i could have seen the intake temps.... id bet they were 175-200F

get a fmic... its not that bad.

wow, my expectations are much too high. 15psi on a stage 1 huh to get 275, and thats before the heat soak.
Interesting... I got a cool idea tho that I just thought up..
Either way im glad to know someone was using the same config that I want.

Thank you all for your help, questions have been answered!

 

is the walboro good for high boost on a single turbo?

 

Yes.

 

my question is why? Why are you bent on keeping the stock IC and ecu. If you are going with a larger turbo naturally your gonna need to upgrade everything else. Espically on a rx7, this is a rotary, you cant get by with the average. Thats how motors blow. If your going to go with a larger turbo, wait till you have the money to afford the other expenses.

 

He's using a Stage 1...it's not THAT much larger. He can run stock ecu with tmic fine. My friend is running a stage 4 with a fmic but stock ecu with rtek 1.7 (i know thats not smart =/) and I'm running a stage 3 with standalone, but stock tmic. Just don't plan on autocrossing with your tmic

 

its not that much larger, but what boost is he planning to run? He will need fuel mods, injectors, walboro pump. What got me was he asked if he would need to upgrade anything. Anytime you start modding a 7 you better start modding the fuel.

 

At a minimum I'd say Rtek 1.7

The 1.8 or whatever one uses 720's all around probably would be overkill but your better off tuning down then tuning up injectors.

Or just fork out the $$ for the Rtek 2.0 and adjust your maps without a safc.

Walbro is needed. FPR would be helpful but not needed.
I noticed my stock FPR was pushing 50-55psi with the walbro.

Hmmm 240-270 range sounds like my kind of turbo. A daily driver with that much would probably kick *** and still have some good spool oomph!

 

keeping the stock ecu is not that big of a deal, trying to make the stock top mount work tripple over time is what's going to get you. Get the front mount!
