Hey guys, I finally managed to get my engine running. Took me ages to get the timing marks spot on but I freaking did it.

The block is N/A, got a turbo head and am running turbo injectors, The intake cam is from an N/A (are they the same?) and running a series 1 TPS and using a turbo ECU. Oh, also using an N/A zorst manifold because I dont have a dump pipe yet for my turbo and the N/A mani has an o2 sensor on it.

I have a turbo gear to go on it but still waiting for some parts to arrive.

My question is, because its an odd setup, what would be the best timing for it? I dont have a timing gun to check what the timing is like, but to me it sounds like its breaking down when I rev it.

Spot the fire hazards...

Id say what ever a 25det timing is, and the break down id attribute to coils possibly

Good point. When I was checking for spark I did notice the coils with no spark plug plugged arcing out onto the coil bracket. Ive always wanted to do an external coil pack conversion might give me an excuse to do it. I just assumed the arcing was due to no spark plug in them and the spark had to go somewhere.

What......

How can you be doing stuff like this and have no timimg gun?

Who cares what timing we tell you to run, how will you run it?

Ill buy one tomorrow

Engine is nowhere near ready to get accurate with tuning.

For the moment set the CAS so she will start easily, sounded a bit too far advanced in the video.

She starts first go and idles without any issues. When I get the gun ill get the timing spot on :) (I hope)

Unplug TPS, unplug IACV.. then make sure your idle is screwed in at 650rpm (as per recommendation for a RB25DET).. then set timing at 15 degrees BTDC.

Car will run ok.. but wouldn't be nice to run.. you could blanket an additional 2 degrees on top to make your base timing 17 degrees.

It's a NA so should be fine (of course check for audible knock).

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.

      Factory oil temp sensor in a RS4V without gauges?

      By MBS206 · Posted

      Sounds like the oil pressure light is wired into the oil temp sensor... As it warms up, resistance on temp sensor reduces, hence more current can flow and the dash light gets brighter.

      R34 GTT AC short cycling ? Normal behaviour?

      By Dose Pipe Sutututu · Posted

      If it's cold in summer, then no issue. If it's cutting out every few seconds and you're not reaching your target temp, then there's an issue. One could be the pressure switch and the other issue could be the temp probe inside the evaporator.
