Parts Review/Pick Ups: Toda S2000 ITBs / Sports Injection

Hey guys.  I’ve had this part for a while now, holding onto it hoping that one day I can resume my build…..  If you guys know me, you guys would also know I’ve done the ITBs thing before.  In a previous life I had Jenvey ITBS. You can check it out here, jesus it’s crazy to think I was only 23 when I made the first post on this blog.  I regret not taking more pictures….

Here are a few pictures off of my flickr of the jenvey units:

When you receive the Jenvey Kit, it’s unassembled, so you have to go about assembling the kit yourself.  The coolant temp sensor port to the right, you have to drill and tap that in yourself.  The coolant line to the left, that is not standard, I had to cut and weld from an intake manifold I had laying around.  Take note of the flange of the coolant exit, the bolt behind that flange is a pain in the ass to get once it is on the car.  I had to use an allen bolt and cut off the head of an allen key to reach it.

You can see how I welded the factory coolant line here, so I can retain the bleed functionality.  I later cut this off since it wasn’t flush with the head…. dummy me, I should of checked beforehand.  Those vacuum ports you see, I had to drill, tap, and screw in each of those nipples…. (Stalker photography was a logo I was working with for awhile… I wonder what happened to that adobe file.)

My Jenveys waiting to be installed

All assembled and glorious looking.  Unfortunately, I was never happy with the fit and finish of these units.  I had to source my own injectors, I went with Ford Racing Injectors 440cc Injectors.

For the TPS, jenvey made an OEM s2k TPS adapter which I had to buy later on….

The problem I have with the Jenvey ITBs, that I’ve always repeated, is that the Jenvey ITBs were not created with the S2000 in mind.  They were created for F20/F22c kit cars.  The lack of thought, i.e the missing coolant bleed port, bad coolant flange design.  Hayward performance remedied this issue by creating their own ITB flange, and still utilize the Jenvey throttle bodies.

I’ve always wanted the Toda Racing ITBs.  I wish I went with this setup from the get-go. The Toda ITBs comes with a Toyota based TPS system and in the instructions how to wire this up to my current setup.

The fuel rail it comes with is beautiful.  Super heavy duty, it’s a billet piece.  The jenvey fuel rail feels like a cheap aluminum tube compared to this.

I love how these are compatible with the OEM s2000 injectors, so that cuts cost of sourcing different injectors and allows you the option of upgrading injectors later on.

For the Jenvey ITBs, I had to convert my fuel system to an -6 AN system.  For the Toda units, all you have to do is bolt the OEM Banjo bolt system to this fuel rail.  Little things like this is what I really like about the Toda system and JDM products in general.  The level is meticulousness is unrivaled by any other manufacture.

The TODA ITB units come pre-assembled.  They are based off of the Toyota AE101 ITBs.  The one I have is the 88mm units.

As you can see the whole is already tapped for the coolant temperature sensor and the flange for the coolant exit, is where the OEM intake manifold is, so it is much more accessible to bolt this to the head…

Same TPS as the Toyota AE101.

You can see how some of the vacuum ports work, there is 2 per runner.

Closer look of the linkage between throttles.

Of course this will plug and play with the OEM throttle cable, while the Jenvey units you have to come up with something yourself.

One port with a barbed nipple already.  Probably for brake booster.

The trumpets feel incredibly solid, as if they are machined out of a block of aluminum.  The Jenvey throttle trumpets felt really cheap to me, you can even bend the Jenvey trumpets by hand.

The capped off vacuum ports on the flange, and on the flange of the runners.

The knob you see in the middle if the main throttle idle adjustment… Not pictured is the coolant bleed port on the other side of the ITBs.

Overall, I’m really excited for the Toda ITBs, I mean it’s the same system that the ASM race car uses!

Life: A Random AE86 appears

I hung out with some friends last week. What I like about hanging out with like-minded car enthusiasts is that they are associated or attract other people that share the similar vision and philosophy when it comes to tuning cars….

Speaking of tuning, Tom picked up a new Intake…. TOP FUEL ZERO-1000 TYPE 3D. I like how the inlet of the intake goes over the radiator. I think there are only a handful of people in the USA with this particular setup.  Loving those Öhlins Tom, we all know the fastest S2ks in California run Öhlins….. 🙂

You can see Colin to the left installing his KCMachine Shorai Battery kit It is USA made and only a combined weight of 6.6lbs! KCMachine makes Shorai battery kits for other cars like the BRZ, FRS, and NSX.

Areen brought his buddy out with one of the cleanest Hachi Rokus I’ve seen outside of a car meet……..

Kouki frontend with a zenki lip.

Of course I asked the owner what he was running under the hood….
Under the bonnet is a 20v 4age with the stock ITBs!  I like how the engine bay is painted, reminds me of how Spoon paints the interior and engine bay of their cars.
I believe he said the bottom end was all Tomei….

Beautiful custom JSP header
Owner is repping HK and AE86FIGHTCLUB

Bride Seats!
I love the accordion shift boot and matching Personal horn to match the seats.

Volk TE37, don’t see too many TE37 wheels on AE86.

I like this shot, the car behind turned on his headlights as he was leaving…….This reminds me of the option videos I used to watch back in the day when they ran the touge in my younger years.

Trueno mud flaps.
I’m happy that owners like this are preserving this car as they are becoming increasingly rare and modifying the car with quality parts that don’t take away from the soul and balance of the vehicle.

Life: First Track Day at Button Willow

Hi All,

This past weekend I attended my first track day EVER at Button Willow Raceway. I was invited by my friend to see off our buddy, S2k racing pro Alex Peng. The track day was hosted by Extreme Speed, one of Southern California’s most popular choice for track days….This day was definitely a day to remember….

I left early in the morning, around 5:30am, Extreme Speed request people to be at the track around 7:30am. Button Willow Raceway is exactly two hours from my house without traffic. I had to make a few stops on the way to BW, one stop was the bank, since I needed some cash for the entrance fee and the second stop was a gas station right outside BW because the gas at BW is extremely marked up, like $2 more than usual. If you just need 91 Octane, I would recommend purchasing it outside the racetrack, if you require anything higher than that, BW has that all onsite, including racegas.

This was my first time ever running a real track event. I’ve done a few autocross events prior on the East Coast. Track days are around $300 on the East coast, but on the West Coast you can sign up for a track day around $100. ExtremeSpeed seems like a popular choice among drivers since they are one of the cheaper groups, but the downside is that they seem to over book their events. Not only were they hosting an ExtremeSpeed track day, they were also hosting a Vtec Club event in parallel with the Extreme Speed track day. My Beginner class alone had 20+ people signed up. I showed up to the track day, met up with my friend and went straight into the driver’s meeting. Most of the trackdays in California are self-tech, which means that you are supposed to tech your own car, there is no one at the event that will go over your car. I thought this was interesting, but then again the price I paid……I checked my lug nuts, oil, coolant, and off I went.

For the beginners, they first make you do a lead follow run. Basically they make you follow an instructor car in your car Indian run style, the instructor is in the front and there are 4 cars behind the instructor and after every lap, the first person behind the instructor goes to the rear of the line. This lead follow is so that the drivers can learn where the correct line in the track is. For me this didn’t really help much, luckily my friend was in the car telling me which lines to take.

After the lead-follow session, the next session you can run by yourself or if you want ask an instructor to sit in the car with you. I had my friend instruct me for this session…. going a bit faster was scary…. to me this was not like autocross at all, going 80…90….100mph vs. 3-4 gear in a parking lot is completely different. Although my friend was trying to help me out, I still did not feel comfortable with my car. I was still making stupid mistakes, such as braking while turning and spinning out my car…. The entire session, I didn’t have one clean lap, I kept spinning out the car for one reason or another….. I need more seat time to become more comfortable with the limits of my car.

The next session, I went by myself, and man was this a bad idea…. I had no idea what I was doing on the track. I felt like I was a danger to myself and the people around me….I should of grabbed an instructor. I spun out a few times and luckily did not caused any accidents, but I was close. It’s crazy to think they would let people with no track experience just go on the track, but then again, cheap track day…..

Towards the end of the day during an Advance session, a driver passed away. He had an off and went into a flagging station. The driver was an instructor and the passenger was the owner of the car. The car was an E46 M3 and the owner had years of experience, over 20 years+ experience! RIP Ivo of Renner Motorsports.

This really made me think about safety, the car was impacted on the passenger side, but the driver passed away…. Usually when we think about car collisions, it always head on, but lateral moment also kills… This made me think “maybe I should look into getting a Hans device…..?”

Now on to the pictures….

ITB + TURBO + S2K?!??!?

This is an oldie I remember from awhile back from the old days of s2ki, pre-2.0.  If anyone wanted to do an ITB turbo s2k, it’s been done before.  It seems like he is using Jenvey Throttle bodies, a custom Plenum, Meth injection, and a Garret GT35R turbo.  According to the thread he dyno’ed at 555whp 370 ft0-lbs of torque at 18psi, not exactly the best numbers for the money spent these days, but I’m sure the response is pretty nice.

Current State

The car is running well again.  I tracked down my random cut off problem to the wiring harness.  Since I cut off the TPS, soldered in the rover unit, and then returned it to the oem unit to use my OEM adapter so many times, I eventually lost enough slack from the connector and the solder was only connecting about 3mm of wire.  When the Alpha-N system did not see a TPS signal, the engine just shuts off.  I used some wiring from the Chasebay harness, which is truly garbage.  When i had the chase bays harness installed, I had a weird grounding issue.  Comparing the Chasebays harness and the OEM harness, you can see that the OEM harness definitely has beefier ground wires that go to the fuse box and to the alternator.  I quickly used the TPS, MAP, and IACV wires from the Chasebays Harness, it wasn’t too hard cutting up a $550 harness I just bought .  I extended the map and the IACV wires just in case I want to use a baller CNC machined vacuum block with integrated IACV and map in the future.
