I've seen mircosquirt in my searches, I''ll have to look more into that as well. Im keeping the bottom end stock (ie: pistons, rods, crank etc) and having the head professionally reworked with the cam kit: Schneider Performance Spring & Retainer Kit New Rocker Arm Set New Lash Pad Set Schneider Installation Cam Lube Schneider Formula 2 Additive Cam Tower Blockoff Plate Kit + whatever cam I decide to go with! (Obviously if I go with a different cam and they have a different kit available I will go that route, but for now the Schneider kit is atleast a good guideline of what I will be swapping out on my head) I like the characteristics of the Schneider stage 4, but have read that they are not as superior as ISKY or some other cam brands.

In CA 1975 and older cars do not require smog checks, so this car is exempt! From the advice and reading I've been doing I am definitely going to be upping the cam! Just need to figure out which one to go with! I've heard good things about ISKY and may be headed that route so we will see. I've got in contact with "softopz" about building a megasquirt kit for this build and retaining the stock intake, so we will see what the results from that is soon!

PM sent!

My main reason for choosing the 4 barrel EFI setup is mainly just the ease of install, its just as simple as throwing a carb back on you just gotta plug in the supplied harness, tell the programmer what kind of cam you have and how many cylinders the engine is, and it automatically tunes itself as you drive. Simple and painless, and retuning for added parts is a breeze. I've been doing alot of searching for some nice 4 barrel carb and efi setups and have come across more than a few that have successfully ran all 6 cylinders with the spark plugs burning evenly. Here is a pretty nice setup (minus the ugly plate under it) for the L28 And as far as the money, the Summit EFI is pretty affordable compared to most EFI setups. I'll have to take a look at the pre made megasquirt kits that the guy is selling on here because that is something I would definitely be interested in, because of at the end of the day I really just want something that is plug n play. Also now I am thinking the stage 4 cam may be better suited for what I want. I would definitely want to be able to rev into the 7000-7500 range at the least. What do you guys think as far as cams go? I do love the look of this though! This is SO clean! Definitely makes me want to consider other options. Just need to figure out what the cost is vs the 4 barrel EFI setup and how difficult it would be for me to setup.

Yep I haven't forgot about the regulator, is it possible to use the stock pump with a higher pressure regulator for the system? From what ive read in the manual the stock one operates around 36-37psi but I couldnt find what the actual fuel pump is rated for. Im still open to ideas and havent spent any big money yet, just have some general guidelines that I have been going by. All I do everyday is read about everything lol Lots of information out there! Nothing is quite set in stone yet, and I'm glad I started this thread so I can get some input from other builds!

WOW! That looks amazing! Alright you have me intrigued! I've been trying to figure out more information on megasquirt, but seem to be falling short. Would you happen to know any specific threads that could point me in the right direction??

I've considered it, but the stock EFI setup seems so cluttered to me, maybe its just me... But the carb intake with EFI throttle body looks much cleaner. Although I want to do what is cost effective too.

From trans to differential on the driveshaft. And for the summit efi I'll need more fuel pressure than the stock fuel injection system currently puts out (atleast 58psi) so i'll be upgrading that. And thank you she is a beauty! As for the camshaft that is the one, although I haven't even considered going bigger i'll have to look into that! I definitely wouldn't be opposed to going bigger on the cam but just need to see if I like the RPM range on the larger cams, and considering ill be leaving the internals on the short block stock im not sure how much bigger it can go, so i'll have to read more into that for sure!

Hello everyone! Im new to the Hybrid Z forums so I thought I would start a build thread for my build on my 1975 280z. Current car: 1975 Datsun 280z Mods: Subaru Power Steering conversion, Full Eibach suspension, aftermarket swaybar + full polyurethane bushing conversion, Toyota front disc conversion, aftermarket A/C installed, 240z driveline, (im probably missing some things so I'll update it as I go.) I have roughly 20 years of receipts of all the work done to the car. I just recently acquired the car so everything listed above was done by the previous owner. Now here is my plans for the rest of the car: [Key --> Green = Acquired Crossed Out = No longer using ] Turbo Spec Motor 7.31:1 Compression (N42 block/P90 Head) Either T3 Precision Turbo or T3 Turbonetics Arp Head Studs External Wastegate + Blowoff Valve + AFR + Boost Gauge Oil Cooler Turbo dizzy 82/83 280zx + shaft Megasquirt EFI kit from Softopz 550cc RX7 Injectors / 440 cc Supra Injectors (For Sale, Message me if interested I will ship at no extra cost) Turbo Oil pump (thoughts?) 240sx throttle body + Sensor Intercooler + Piping Oil Pressure T for oil lines to turbo (in & dump) 2mm head gasket to lower compression to 7.8/1 wastegate Downpipe (need a dump tube as well for the wastegate) Turbo Manifold(x2 anybody want to purchase my extra?) + wastegate adapter 2.5" exhuast / black widow widowmaker Upgraded Ignition System (not sure which to go with yet, suggestions??) NGK Plugs Pallnet Fuel Rail Kit + Throttle Body Spacer Electric fuel pump upgrade + New Pressure Regulator ------------------------------------------------- UPDATES: Update 11/3/2017 - With some great info/advice from the comments, I am highly considering going with a megasquirt plug in play kit made by softopz (just waiting on his reply at the moment). I've also decided I definitely DO want a bigger cam, so any suggestions on that front are helpful as well. Also I have added that if I go the megasquirt route I am ordering a pallnet fuel rail to compliment it. Update 11/4/2017 - Alright after meticulous research, hours of comparing prices and talking back and forth to people who have done the cam/turbo builds and the potential power gain (and I do mean COUNTLESS hours of this haha), I have decided to completely ditch the whole cam and head upgrade idea and go the turbo build route. For almost the same price (actually a bit cheaper) I can get alot more smiles per gallon with the turbo build. There just isn't enough power to be had on the N/A build for the amount being spent. So as of right now this is the game plan. I will continue to add to this as I see fit, everything will be updated on this original thread post. Part 2 11/4/2017 Just went through the receipts on the car (dating back to the late 90's) and boy was I in for surprise! All of the tedious work to maintain the stock L28 has been completely gone through by the PO! For example the timing chain kit from Z Motorsport has been installed, Tune up kits routinely done, fuel pump and filters / lines replaced, harmonic balancer replaced, and the list goes on. I couldnt be more happy with this purchase!! Did I mention the PO gave me a close ratio 5-speed for the car?! This car amazes me and I am very thankful that it has had such meticulous care over the years. Update 11/7/17 Added some parts to the list. Also purchased a turbo manifold on facebook for 150 bucks! ***Update 11/10/17**** I have purchased a complete L28 turbo motor setup at a very very good price! Here are the engine specs: L28 N42 Block with dished pistons, P90 Head, N47 intake, turbo manifold, Pallnet fuel rail + Fuel pressure gauge, 440cc supra injectors, rebuilt chinese housing turbo with turbonetics internals, turbo dizzy, and assembled with ARP studs. Came with some other misc parts as well. Update 11/13/17 Link to spreadsheet for parts list: https://docs.google.com/spreadsheets/d/1iOiWBJyjQH3KEkLnBor0snwgOvXaUo4I0qIo1ZDYFZo/edit?usp=sharing Update 12/7/17 Tore down the entire motor and I am going to rebuild the bottom end and the head and all freeze plugs timing chain etc... Ordered all the parts just need to hot tank the block to start assembly again.
