ok, to make a long story short. i bought an engine from a jdm shop. the engine had a garrett turbo a/r .50 , 2 additional inj.

turns out the engine is ported, and when i say ported,... its bigger then fd ports. on the intake and on the exhaust. my friend (who's my mechanic, and has been working on rx7 for around 14 years) told me it looks like its bridgeported and it has a exedy triple plate clutch.
the thing is since i brought him my car and the engine last week, i sold the turbo kit and additional inj tb elbow.

so in conclusion, my questions are....
1. for a little while (let say next summer) is the engine driveable with the oem injectors, stock turbo @ 11-12 psi (with ported wastegate) with the stock TMIC, 3-puck racing clutch, rebuilt and upgraded FB radiator and racing beat complete rev2.

2. With a BNR stage 3 or 4, bp engine, 720cc secondary, wahlbro 255 or bosch fuel pump and rtek 1.7 , can i still keep the racing beat rev2 or is it too restrictive ??

3. And can i keep it TMIC or do i really have to go with a FMIC ??? if i have to go with a FMIC, any feedbacks on the corksports intercooler ???


i dont mind having only 350 hp. all i want is realibility with a bit of power.
i bought a jspec engine cause i blew mine, i thought it was a stock engine with a few mods... and i end up with a bp engine with triple plate clutch and bigger turbo. my friend estimated the whole setup the guy had at around 500hp.

so, any help would help !!!

thanks !!

ps: ill post pics a little bit later !!

 

What are you using for fuel control? The stock ECU won't run a bridgeport. I doubt the engine made 500hp with that turbo.

 

okay if your mechanic thinks that maybe is bridgeported(not sure)then look for another mechanic cauze is easy to know if it is or not bridged,just stick a dam finger on the intake port and done,nobody will stick a turbo that small on a bridged motor,about the clutch every jdm motor that i got in the past came with GIKEN,EXEDY even HKS multi pressure disk setup and only one was ported and no you cant run the motor if is really bridged with any stock injectors,computers,ecu,intercooler or hybrid,you are gonna need a real turbo with a divided hot side,big injectors and EMS.


scratch this of your list please
720cc Big NO (only good for primaries)
Hybrids(not worth it)
Rtek 1.7(are you kidding)
stock turbo(trash it)

You are gonna get people telling you that it will work but i can tell you right now that those that will tell you that is fine to do it have never driven tuned or owned a BRIDGY.I owned HBP and now im driving a FBP and you are gonna need to upgrade almost everything to make it work the right way

 

listen to him, you should have kept the parts it came with. If it was a full bridge no way in hell its gonna run with a stock ecu, much less with stock injectors at 12 psi with stock turbo, you'll blow up in no time.

 

.50 A/R? I don't know how that will work on a rotary.

 

Compressor side.

 

1st off, hes not sure if its a big streetport or bridgeport. he barely had time to look at it in details. all he had time to tell me is that this was the biggest porting he has seen in 14 years. and he has seen and done a lot. he had over 40 rx7. over 10 fd with single turbo setup. he rebuilted his engine in less 10 hours 3 weeks ago.

but anyways, to go back on topic. if i go 4x720cc, rtek 2.1 with safc2 or would i need to go with a haltech or microtech, fuel pump, and t04r or gt35r ... AND no matter the setup can i keep my racing beat rev2 exhaust !!!

any good infos would help, all i wanted was a small streetported engine with a 320-350 hp setup.

thanks guys !!

 

ok, guys, i have a little update. my friend called me, the engine is not BP, but its aggressively streetported. its running 2mm apex seals.

so any help on good setups for 320-350 hp.
give me some ideas, on the setups you guys have and all...

thansk for your time and help !!!

I have an aggressive street port with a BNR stage 4 (one I get it re-rebuilt) 1600cc secondaries, full standalone, FMIC. That setup, I'm expecting about 380 rwhp at around 14psi. This is professionally dyno tuned with all of the supporting mods such as fuel pump, wideband 02, FPR, FMIC, oil and water temp gauges etc. How reliable is it? Who knows. As with any non-stock, boosted rotary, you have to keep an eye on your A/F, fuel pressure, and on your temps.

If something is not right, shut it down and troubleshoot. Maintai and monitor is how you keep it reliable. Oh yeah, and don't get power hungry and overboost!

 

nice, those are great numbers.
which standalone, fuel pump and wideband are you running !??
you still have the 550cc primaries or 720??

dont be shy, if you have pics, its all welcomed !!!

I have a similar setup, BIGASS streetport, TMIC (ARC not stock), 2 extra injectors (1600's controlled in glove box lol), and I'm running 16 psi on a t3/t4 t04e turbo (yeah.....I know Upgrading SOON!) You should have kept what you had, especially with that port stock injectors are not gonna cut it. +1 to mikeric. Make sure your fuel system/ EVERYTHING is actually what you need and monitor!!!!!!! Wideband O2 FTW
