It will get checked again. Fingers crossed. It will go back to the machine shop to get decked again and re lap the valve seats. first it needs to go in a large ultra sonic tank.

Well sadly my ported E31 head was in an engine shop fire. Luckily my 3.1L was pretty far away from the flames. Well lots of elbow grease and 4 hours in my vapor blasting cabinet and it looks as good as new!. Now time to have it put back together.

I have a dyno tune session booked. But the tuner kind of rubs me the wrong way. I love unique things and a challenge. I also hated the black bodies of the Jenvy. The SK look rad. That being said I think I would pick borla if I started over.

In the IAC settings, you can turn on idle controlled via timing. I had that off. It seems to help. I have a noisy tps as well. Something I might try is grounding the shielding? Or I might re-run that wiring set. I would have to look at what plugs, but they are stock efi? Or something of that sort.

A little update on my ITB build. In the middle of this build I decided to buy a historic building and renovate it, then have my first child, so everything got pushed to the back. I am finally finding time to work on it all again. I think one of my biggest issues was voltage from my old alternator, upgrading that has made everything more happy. Well finally got my osgiken clutch out and went with a stage 1 from exedy with a lightened steel flywheel. The osgiken was way too hard for me to street drive and my wife hated it. It was poorly installed by me and it's a pretty racey clutch. I sent to Z car off to a guru. Andrew Kazanis, he swapped the clutch, found my clunk (exhaust hitting during load) and change my rear main seal. Then his buddy Matt finally fixed my passenger regulator. Which hasn't worked in years. I went with a repopped one. Matt thinks my rear end is a little noisy, but Andrew can't hear it. I cannot thank Andrew enough for all his help. He is a friend and just an all around great guy. If I was to start this over, I would pick an ECU that someone in the area knows. I think ITB is something I jumped into, without enough knowledge or money. So many small issues popped up, and all stopped or slowed me down massively. You really end up chasing your own tail a lot, trying to do all of this. A few on here and on facebook have helped a ton. Tioga, Richard Boyk, Rodney have helped so much. Maps, settings etc... Somehow they have completely different views on pretty much all of the maps, but all are very knowledgeable and all know a ton more then me. It will be interesting as I road tune which maps/ settings I like more. Haltech is nicely made stuff, but I found their original software extremely hard to figure out. They have since done a massive massive upgrade (NSP) and it's much easier to use now and much more intuitive. Also tells you when settings and maps are in conflict. Which is huge! I am getting pretty confidante and I think I have all the small ECU settings correct. The ECU should start self tuning. So time to drive her and get it running right. I literally got stuck for months from one stupid box being checked, I couldn't get the idle right during cold starts! IAC or not. I will most likely attempt to use IAC again. I have it fully plumbed and wired, it's also a learning feature of the ecu, so it should be the best route for cold starts. I will turn it off after say 100 degrees, which the motor idles fine after that. My hand throttle works, also using timing to help cold starts also helps a ton. Also don't rip out perfectly good jenvy throttles, for vintage SK throttles unless you are dumb:)

What a great part for the z community. Fully sequential!!

I zinc'd most of mine. But painted part. I don't think 100% zinc is a good idea. Check my build. It has picture of it.

The chinese pumps valves seem to be one of the fail points. Maybe I got unlucky, but mine died quickly.

Nice! I rebuilt and sold 10 or so of these over the years. I used Nos other Nikki pump internals on mine (most cheap off ebay) The screws were perfect on the NOS. Then I sent the inlet and outlet off to zinc, then vapor blasted.

Datsun Spirit plugs the bottom, then just a breather filter at top.

I will take the turbo dizzy! Pm'd

If your strapped for cash, building a race motor should be pretty far down the important line. DSI builds some pretty motors and has come up with a lot of innovative products. Their youtube channel has one of the best if not the best sounds L series video on the internet.

Dry blasting the valve cover prior to vapor/ hydro blasting will yield it better looking.

Ha! This is sitting in a box. Yes, I have been sending parts off to zinc for years. Cheap and easy. The finish is vapor blasted.

I vapor blasted and rebuilt this one. Fairly easy

Only looks like they have L?

The rubber ones are Nismo and were part of a kit Nissan sold for L6.

Well I won't stop ****ing with my car, so I only have like 400 or so miles. Works perfectly. It's one of my favorite mods.

The usb cable that came with my haltech would always crash. I replaced it, and it don't have issues anymore. Maybe try that first? Currently i have zero screens/ filters

Taka or Mike Malone always have some, but get ready to spend some coin$. The mikuni facebook group is also great.

I think I have all the kinks worked out. Time to road tune. FullSizeRender.mov

Driving a car is dangerous stuff. Probably the most dangerous thing we all do every day. Soon our cars will drive themselves and the death rates will be fractional of what they are now.

My 2nd set of vintage SK throttles are just about done. Only think left is to come up with a tps solution. They are a gift to my 3.1L engine builder Andrew.
