I have a 1990 6-port Rx-7. I havent finished the project yet but my goal is 350 hp and I'm curious if this set up makes it possible:
Port matched TII intake manifolds
Borg warner S362 turbo
Turbosource exhaust manifold
Single exit exhaust(fab)
Link monsoon with custom wire harness
AEM water meth injection
Bridgeport (not super intense, but idk if it's considered a half bridge)
CX racing intercooler
Turbosource Studs
koyo rad radiator
just looking for 350 rn. I'm 17 and all this has been budget over a year, and I think 350 is good for me for now

 

i would say that the hardware should do 350hp pretty easily. with a bridge you want to keep the pre turbo pressure close to intake pressure.
it might depend on the turbine housing you picked. if it was mine i would start at the lowest boost and maybe keep rpm reasonable (6500?), and just start tuning.

compressor is good for around 500hp, so you have plenty of capability there

 

A couple of questions:
1. I was thinking a bridge wasn't needed to make 350whp with a turbo.
2. I also thought water/ meth injection wasn't needed if you didn't use the top mount and went to a front mount intercooler. Though he didn't mention what his plan was for an intercooler so the water/ meth may be to keep the stock top mount location.
Am I completely mistaken? My eventual power goal is also 350whp and I have no plans to do either. I won't be using the top mount as I don't have a TII hood nor will I be using the TII UIM (FD upper). Will initially be front mount.

 

for me the bridge is for the braps. Nothing more. And the water meth is because my tuner has done a few 6-port turbo builds and says it's essential if I want the motor to be reliable. The water meth is there for reliability. Both arent for performance, just for quality of life. I'm okay with more than 350, but that's what I'd be okay with.

 

I thought it might be due to the higher compression n/a rotors.

 

which one? Bridge or water meth? Cuz I think the water meth is for that but idk abt the bridgeport. I just want braps lol

 

The water/ meth injection.

 

its a reliability thing my tuner suggested. That's why I'm installing it

 

its not, the old HKS catalog has you at ~350hp (not sure if its at the engine or flywheel) with a stock engine, sport turbo, front mount, intake exhaust, and ecu

IMO i don't think you need it for 350hp, especially if your other temps are good.

 

I think the biggest reason for the water meth is because my motor isnt a 4-port. It's an N/A converted to turbo, so it has higher compression and isnt as strong as the actual turbo motor. The bridgeport I purely want for the braps tbh lol

 

The bridgeport adds braps but makes driveability tuning a lot harder.

 

350 wheel or???

I just ran my S5 6 port for the first time. running 12psi on a BNR Stage 3 turbo on a stock port 80,000 mile engine, Haltech 1500, I managed 283 to the wheel at 7200 rpms on E85. This was a chassis dyno bolted to my hubs. I told them to increase the cutoff to 8000 but the safety kept engaging I believe.

 

I legitimately was you 5-6 years ago. Prepare for many thousands of dollars and hundreds of hours in the garage. You will be very satisfied once you make it to your goal.... I would recommend a 4 port motor and a haltech
