Project 240Z Turbo ITB Install

Recommended Posts

Sorry mate, was reading at work which sometimes (often) means that I'm skimming, trying to catch the major points of a thread. Now that I've read it, I support it!

 

 

Well, there isn't really a reason not to I suppose. I just don't see a compelling reason to go to all the extra work/expense for ITBs when a decent plenum performs just as well on a forced induction engine. Correct me if I'm wrong, but I don't think there's actually a performance gain there.

 

drummingpariah, just as a point of reference, TimZ's car uses ITB's and likely makes more power at ~710bhp than any street driven/driven turbo L28 ever in the history of time. :shock: A large intake plenum on his car might make the similar power but the results of his ITB setup is hard to dispute.

So after an uneventful weekend I pushed myself a tad bit further back. In my “let’s make it look pretty yet functional†attempt in wrapping the SDS harness I jacked up a few Weatherpack connectors in trying to remove the pins vise cutting and soldering them. On my last two 3 pin connectors and my “tool†pushed the wire out and left the terminal in the connector. I was cheap and used a Craftsman pick not ideal so I have learned..

 

Weatherpack connector in question:

So now I have an email into Ross to have some replacements ordered or get them online.

 

Does anyone have a method or a tool recommendation to remove the male and female pins?

 

I found this for $7.50 specifically for the Weatherpack connectors:

I ordered and received the Weatherpack crimpers, removal tool and connectors from HiPo Parts Garage back in July. Let me tell you when you have the right tools it makes the job so much easier. I also picked up a nice set of jeweler flat head screw drivers from Radio Shack.

 

As of last weekend I am 80% done with the EFI harness. I had to order another 60 feet of the Raychem DR-25 Heat Shrink Tubing 3/8" and the best place and price I found is Prowire Motorsport Electrics I used them before and they are great to deal with. I was running low on the 3/8", so I jumped on the O2 sensor and finished mounting that. All the parts should be in before the weekend so I can keep moving forward. I'll have updated pics after this coming weekend.

 

Getting there: :trippen:

After couple of hours on Sunday and a few hours this week after work, the entire SDS EM-4 6F harness was been rebuilt with new Weather Pack terminal pins, connectors and Raychem DR-25 Heat Shrink Tubing. I also installed StreetWires Firewall Bushing using the old a/c refrigerant line holes under the battery tray. I am getting very excited I am very close!!

Wiring is done under the hood. :D

 

I don't think it looks too bad for my first time building and wrapping an EFI harness. The wiring harness and spark plug wires are roughed for now I'll clean it up more later.

 

Check it out I am so freaking happy..

I used the existing holes from the a/c. When I paint the car I plan to cut out that corner and replace it with a cleaner one and put the harness somewhere else...
