From N/A S130 to Turbo Drift Missile

I have been busting my brain-balls trying to get this ignition thing sorted out. Many solutions have been tried and I ended up frying a CDI module and I think I broke the optical trigger. So I built a new one.

After testing many different setups with mixed results, it was time to call it a night. I'm exhausted. Until tomorrow...

There have been many late nights of tuning and trying different setups only to still not have it start. I've ordered a replacement XR700 optical sensor as I suspect my frankenstein sensor may not be up to the task of automotive use. It should be here tomorrow. Fingers crossed.

Thank you!

 

Its running. Its moving. Got a basic tune done to at least take Watson around the block. Huge thanks to my buddy Zach for helping out with the build. It took just over a month to make this all happen and now its all about tuning to get it to run great. Stay tuned to witness the true power of Watson the Datsun!!!! tongue.png

The issue turned out to be a far too low value on deceleration enrichment. Interesting. Anyway, I change the value from 5% to 100% and bam! No more cut outs or lean outs.

 

Got a little bit of tuning done today. Watson is running great! I had to give it just a little gas to hear the turbo spool up. As it turns out, blow off sounds are quite rewarding. tongue.png

On the way home the fuel pump decided to it was time to start dying. I just happen to have a Walbro 255lph fuel pump laying around. That will go on tomorrow.

This thread may be a little dead but I've still been working on Watson. I actually have my first event coming up on the 19th and I've almost got everything sorted out. Here's a small shake down run. Just a couple more parts and we should be solid. Oh, I should also note that I did end up replacing the entire fuel system. Rust in the tank and lines is not conducive to a healthy engine.

Gross.

Shake down run.

It didn't. I couldn't solve the timing issue in time.... So I installed a CAS today because the optical trigger decided to walk around and screw everything up. Now I have rock solid timing and I can finally take it to redline! It goes real fast. Time to get it on a dyno for proper top end tuning.

A buddy of mine and I decided to do some random what-nots to the Datsun. We made this. A wooden dash and a fender exist of the exhaust. Pics of the final exhaust setup once the stainless steel plate is on to take up the slack cut-out area. Video tomorrow of the sound. I can't wait to start it up!

I started making a hydraulic e-brake for the Datsun using a beer tap handle, a Honda Civic clutch master cylinder, and some steel. Almost done, just got to add a swivel to the lower joint and clean it up. Don't make fun of my welds; I know I suck.
