    280zx ignition module with Megasquirt - is it necessary?

    Looks like minimalism is the trend here. Actually I think that is better, lost an engine due to the driver didn't see the gauges. Just to much information for the driver to process. If it had been a single light it would have worked. Never heard of splunk, looks interesting.

    Love it. This thread has just turned into a Dash beautiful context. The display is a raspberry pi running Race Capture Pro and Tunerstudio. Car also has internet so you can login over internet via VNC remotely and tune the car. Race Capture pro is used for speed/gps/track timera and so on. That is also displayed online using Podium Connect, so you can see oil pressure and stuff online in real time. I wish I had good fabrication skills....

    I removed every wire and every electrical gizmos (ECU relays etc). Saved 25lbs! Please show me your dash, I also redid every wiring with Megasquirt and custom "fusebox". But still looks like crap. Need some inspiration.

    Got it! Looks great, not sure why I have 1000000000000000000000 more wires than you going all over the place.

    That is very clean! jealous!! IS that the complete harness??? - Where is your alternator wires? - Where is your map wires? - Where is your airtemp sensor wires? - Where is your oilp or oil temp wires? - Where is your trigger wheel wires?

    All forged pistons floating pin type?

    Thanks! That is useful information! Decided to reuse a set of dished pistons with new rings, will have the shop hone the block. A little less oomph than with flat tops and earlier shift point but turning this into a budget track beater. Want to build a nice race engine or turbo at some point in my life, saving the money for that. Those DSI piston and rods looks awesome! Well, it's a busy machine shop in Austin. Haven't heard about any screw ups and they have been around forever but my gut feeling says that you shouldn't trust them with specialized non American engine work.
  7. Hi, I am looking to get forged pistons to my super reliable NA track beater. Are all the forged pistons floating pins? I would like to avoid floating to make life easy and less stuff that can go wrong: 1. The "clip' might be installed wrong (by me or machine shop) 2. Some uncertainty about what bushing to use or not to use 3. Adding a oil hole to rod seems like more work that can go wrong. Forged is borderline unnecessary but will give me a piece of mind. My optimal shift point is probably going to be at ~6500 but I want to be able to over rev all the way to 7000 RPM. Reason for this is it can save me a shift, shifting takes time and can upset the car and more stuff to think about (if you are a newb like me). The intention with the engine is to have something reliable that I can beat on and don't have to rebuild. Thanks
  8. Hi, My newly built race car engine blew up. I just want to get my car ready so I can start racing again. 1.Would it be a terrible idea to just throw the head on a junkyard block I have laying around in the garage? It's the early dished pistons. 2.Can the stock pistons survive hard tracking with shift points around 6500 and occasional overreving to 7000 rpm? Debating if I should get new rings or just throw on the head an go racing. Engine is a 200hp ish L28 with cam, ms and polished head. I am fine with the potential loss of performance with dished vs the flat tops I had.

    SCCA ITS built L engines?

    This is a new level for me, I am more of a slap everything together while kids are a sleep and hope it works (so far it has). But only built 2 engines so far, maybe the 3rd can be a little more detailed. It's very cool, seems like there is plenty to learn.

    SCCA ITS built L engines?

    I think they are a little slow in stock configuration compared to a modern engine. But I agree, I also think they are great engines. Durable, easy to work on and has a surprising amount of potential. But either way, how do you get 200hp out of a stock L28? Mystery to me

    SCCA ITS built L engines?

    But how how how how how These are the obvious mods that are allowed: - Megasquirt (using dizzy not trigger wheel) - Headers + Exhaust - Cold intake - .040 over (but same shape, so no flattops on N47) - Intake match to head - Valve guide can be changed (but no head work?) - Retard / advance cam (at least it's not mentioned not to) How do you get 208 hp from that?? Tony where are you?

    SCCA ITS built L engines?

    Hi, Considering the age the Z cars seems to be a popular SCCA ITS engine. It's a bit surprising since the engines has to be more or less stock under ITS rules. And we all know what a turd a stock L28 is.. But I remember seeing a post on this forum that ITS built L28 actually had significantly more than the whooping factory 135hp. Anyone has any more details about these engines? How is it possible to extract any power out of the L28 if you are not allowed to touch the cam? (I guess it applies to the L24/L26 as well)
  13. Hi, I have a freshly built engine with damaged pistons and scratched cylinder walls. My plan is to remove the crank and have it bored for new pistons. I can still reuse the main and rod bearings right (as long as they are in spec)? Removing the crank, rebore and press on new pistons shouldn't hurt the bearings. Or are they one-time-fit only? I will also reuse my ARP rodbolts, this is ok according to manufacturer. Someone told me you can't, I can see how you typically replace those while you have everything apart but in my case they are "brand new".

    L24 build, I need help!

    Don't know when your carbs are going to be the limitation but this is how I see it: - over 6500-7000 RPM needs forged pistons for a reliable build. This would require boring and getting new pistons, a bit over >$1000. So very high duration cams might not be needed, maybe a 280/290 duration would be enough? - Over .460" lift and you need different springs and seals. So if you want to make life easy you take a cam with a max lift of 0.460". If you want to machine your head then this wont' be a problem. - Over .480" lift reground and you typically need to mess around with thicker lash pads and aftermarket retainers. Not rocket science but takes a little time to fiddle it. - High lift cams might need valve pockets cut out from the piston, there is no rule because there are many parameter but typically a 300 duration 0.550" lift cam would probably need it. A 280 duration 0.480" probably doesn't. But again, other factors that determines your piston to valve clearance. - High duration and high lift really needs a good head. Stock head flows badly at these operating points. The required work for a 8000 RPM head is typically more expensive then head work for a 6500 RPM engine. Bottom line is that race cams and stock heads is a waste of money. I would get a Isky L-490, I think over that and that head might be a limitation. Do you have any flow numbers on the ported head? For my first build I got a 280 duration 0.480" cam and cast pistons, it's a nice sweet spot and pretty easy to build. But seems like you want to be a little more aggressive. Anyhow, there are a lot of factors.....
