Has anybody that has added a turbo to a late model 280zx with the small plenumed intake manifold seen any severe adverse effects? I'm going to be milling the injector pockets on the intake to accept 14mm injectors and if there is a major drawback id rather find a 75-80 intake and mill that rather than do it twice.

Sorry I did switch to the AEM trigger wheel away from the stock 360 slot wheel.

Not my first go around. Just been 10ish years since ive messed with a turbo L-series. Or any L-series. Or any project car for that matter. My old 260z was L28et swapped with MS and a holset HE351cw. Big injectors, Big intercooler, ZG flared. 240sx transmission swapped, z31 lsd diff. 280zxt cv axles. 12.8 at 110mpg on street tires at 14psi because my clutch was slipping(normally ran 20psi) You know, how you built a fast car cheap 15 years ago...... Cam and crank signal are through a Nissan Optical CAS from a Ka24e out of a D21 truck that I modified to use the stock NA oil pump shaft. The car is running currently but not well due to 2 pretty clogged up injectors. So that part is taken care of. I just wanted another set of eyes on what I'm doing to double check. Speeduino is similar to MegaSquirt but its all open source and is being currently developed. I understand why DIYautotune needs to charge so much to stay in business. The price point has gotten so high that your getting close to more robust standalones. Haltec, Maxxecu, fast, Holley etc. My speeduino was under 200 bucks. another 100 for the wideband from 14point7. It uses tunerstudios as an tuning interface just like MS does. Thanks for looking it over. Ill post a follow up once its up and going.

Well Here is hoping I havent missed anything.

Hi everyone. Im currently in the process of building a 1984 maxima wagon. I am turbo‐ing the stock l24e for now till I can find and machine a turbo engine to fit a from sump. I know the l24e crank is weaker but I'm not looking for 400hp. 180-200will be fine for now. Below is my set up and curious if I'm missing something. Stock L24e. Mn47 head. Compression is 170psi across all cylinders Ecu is a speeduino stand alone runing batch fire fuel and wasted spark on 6 individual LS truck coils. 14point7 wideband 52lb high z 14mm injectors. Billet dash 8 rail. Aeromotive adjustable FPR Running the stock 5/16 feed and return lines which should be fine for my hp goals I think New 280zx turbo fuel pump Stock l28et turbo manifold, turbo, and down pipe. I have the oil feed sorted out. Just need to have a line made. Stock intake which is the same as a late 280zx small plenum intake(curious if this will be an issue) Stock auto transmission till I can manual swap it. Things I think I probably should change but have not addressed yet are switching to a turbo oil pump. And I need to switch to a colder spark plug. I know this is a high compression engine but it is the mn47 head which is a high quench head which helps with detonation. I can wire in a flex fuel sensor if I need to run e85 or e30. Both are everywhere around me. Any thing Im missing or words of advice i would appreciate it. Thanks

I emailed you also @Mayolives

What I mean by wont drive is if you give it gas under load it stumbles and coughs. In park you can get it to rev up decently but only if you slowly apply throttle. Yes the Levi oi us owner has messed with all kinds of things. Chts ohms out correctly and so does the maf. He had all emissions stuff take off the intake manifold but I've put it all back on correctly I believe.

Hi been a while since I've posted on here. I just bought a 1984 maxima wagon. It has the l24e in it. The efi system is the same as a 81-83 280zx. The person I bought it from works for deatschwerks. He was trying to get it running and the injectors where stuck. So he threw a set on he got free from work for a vanagon. They are high impedance though. I've got it running at idle ok but does not drive. Anybody have any experience on this. I know it's a long shot and I will be switching to speeduino but I'm just trying to get it going the way it is. Thanks

Hey, I'm needing a set of NA injectors for a 84 maxima I'm working on. Do you happen to have a set? They are the same as the 280zx NA ones. Thanns

Not a 240sx trans. Shifter is all wrong.

Not Mine. Mine was close but I had fender mirrors. Those are the Rota RB or RBR's from the group buys what? 12 years ago? Rears are 17x9.5 and front where 17x9's. The overall quality of the paint and everything on this car is/was nicer than mine also. Those look like some generic mirrors from the zstore or blackdragon(still around?)

Amazing Derek!! whats red line on the one in the video? it sounds like its not breaking a sweat at 7k and is begging to be reved out. Also, what transmission is he using? I think I see paddle shifters on his steering column.

I was thinking I had also. Guess I was correct. I remember he seemed very genuine. Sad to see him go.

In my 260 it puts the shifter right in the middle of the hole.

What are you looking for? Like what condition? Are you wanting a turn key or a project that has had a lot of the work done?

I have a few but they need to be over bored. Is that something that interests you?

Something is off on that dyno sheet. The torque and Hp dont cross at 5252. It mathematically has to cross there so I'm not sure what is wrong with the dyno chart or the dyno.

I like where this is going. Im just curious if we are going about this the wrong way. Instead of us modifying it. Why dont we contact the vendor. The changes needed wouldn't add to the production costs any or if there is an increase, it would be small. The company is already set up to make these efficiently and the hard part is the splines which wouldn't change. The rest is just a different profile to make it suite our needs. I'm sure someone on here would draw it up. Seems the simpler way to go...

Umm why do you need head studs and MLS head gasket for 250 HP? The only thing the MLS is going to get you at that HP levels is broken ring lands or bent rods instead of just a blown head gasket when the engine detonates.

Run stock rods. You don't need any more for your HP goals

Mike, Its been an honor to watch your journey. Sometimes enough is enough though and we understand. I wish you luck in everything.

Agreed. And you can fit the factory A/C from a 280z in them also.

I don't know what my machinist set mine to but I know that it isn't an interference fit and slides right together.

Hey Mack, Did you ever get your cams reground and installed? After a few major delays getting my heads rebuilt and MAJOR miscommunication from Motorsport on my cams I ordered. My engine is finally going back together this weekend. I went with MSA's stage one cams which are just under the 131H grind you went with on lift. Just curious how you are liking them and if you noticed any power increase and/or fuel mileage increase.

HAHAHAHA 200 bucks for a that? This is an old trick people have been doing for years. http://atlanticz.ca/zclub/techtips/tempsensorpot/index.html
