I also managed to attach a S5 TPS to a S4 throttlebody by fabbing up a simple bracket.

 

Then the new BOV HKS SSQV 3

 

ACT 6 Puck Ceremic clutch, good for + - 500 hp

 

To free up a pwm on the Haltech and utilize the idle control system, Rising RPM makes a nice GM IAC to BAC Manifold. I just happen to have a spare IAC sitting around from another vehicle...

 

I also decided to go ahead and up the compression ratio past the S5 TII by changing the rotors out for a set of S4 N/A rotors. The 9.4 : 1 ratio will make that BNR Stage 4 spool like a beast...

 

Performing part of the Haltech Intstall using Weather pack connectors.

 

Looks nice! How did you get your rotor housings and front cover so clean looking?!

 

everything looking good. lot of info for me to steal .

off topic. what is the BOV that make Chu CHu Chu sound mostly on supras

 

Sand Blaster (white bucket on stand in the back), but first I dipped everything in a tub of simple green full concentrate for 24 hours. I hear pine sol works great also.

 

The HKS SSQV 3 I have has changeable inserts that make different sounds when they discharge. The one I have installed now is a chirp followed by a whoosh.

 

Thats pretty sweet looking, it may take some time the write the cnc to run one though.

 

i am talking about the bov at 4.50 on this vid

 

That is compressor surge called flutterdump from not having a large enough BOV or a poorly tuned BOV... When he let off the trottle the compressed air is bouncing off the throttle body back at the compressor and actually spinning the turbo backwards. That is very bad for the turbo and the engine.

 

You can see this happening further down at 5.06 on your vid, that type of surge is caused by not having a large enough wastegate. The wastegate is not allowing enough exhaust to bypass the tubine causing the turbo to overboost the motor. S4 rx7's are notorious at doing this when removing the cats and installing a downpipe on the stock turbo. That is one of the main reasons i went with the BNR turbo. Bryan tweaks the wastegate early on his S4 builds.



I would bet money that this guy is running a stock turbo with no bov, a boost controller cranked wayyyy to high with an turbo back exhaust.

 

Read the comments.

 

I finished the wire tuck and moved all of the relays and fuses to the area by the brake booster. I also have relocated the battery behind the passenger seat for better weight distribution. Pulled an e-fan out of a 97' Mercury Villager and it is perfect. Has a three wire one for “High” speed and one for “Low” speed a four and five pin relay and two temp switches will drive it perfectly. Next is removal of all the engine bay components and blasting the whole thing. A fresh coat of paint and a sweet looking engine plus no clutter. I cant wait to see it when its done...

 

 

The bellmouth showed up today and it fit perfectly. Plus I get to reuse my K&N from the first build.

 

 

Great looking car

 

Make sure you clean the sand blasted parts really well..Sand gets in all the cracks and crevices..

 

You're going to be running the Velocity Stack and the K&N at the same time or what? Got a little confused on that.

 

I am going to run both at the same time except for track days and I may still run the filter. The velocity stack will still do its job even with the filter on it.

 

The parts where all dipped in degreaser, pressure washed and blown down with air before they made it into the clean room. I plan on a second wash down before final assembly just to be sure I didn't miss anything.

 

Finally collected a pair of S4 N/A Rotors and cleaned them up. Some before and after shots.
