Building an L28 (NA)

Recommended Posts

Been a while since any updates, hows your motor coming along?

 

As of now, Eiji hasn't started work on it. I asked him to hold off until after New Year to start on it, for financial reasons.

I think my final bill is around $12k with shipping costs and all, and currently I'm about half-way clear. If he had started on it already, I wouldn't have the full amount paid by the time he'd be done with it, so I asked him to start later so I could pay him accordingly.

 

Thanks for checking in! Once the build actually begins, I'll update you guys.

Hey Swede does Elji do all machining in house? Also in your discussions with him did he mention whether he uses a torque plate?

Yup, all done in house, from what I understand. No mention of torque plates. I've had about 60 emails with him thus far and most of them have been regarding goals and motives and not so much about actual procedures. As I've mentioned, this is my first involvement with an L28 build, so throwing out procedures first hand would result in everything flying over my head and just cause confusion on my end. I have since done a lot of research and can now better understand the work being done to this motor, so Eiji is going to follow me along as the build progresses.

 

 

My god cannot wait to see this come together.

 

Tell me about it! I am really excited. Having spoken to Eiji about the goals for this motor, I have come to the conclusion of what exactly it is that I want. I want this motor, and eventually the whole car, be a representation of what a Japanese supercar of the 60's would have been like. Something that would fit right into the same alley of 250GTO's, D-Types and GT40's, as examples. I compete in a lot of motorsport (started karting when I was 4-5) and I've had the honor of driving a lot of these ol' supercars at historic events. There's an essence there that modern cars simply don't have. The Z, to me, has that essence, but it's missing the character. The motor, I figured, would be the heart and soul of the build, so that's why I wanted to start with it first. I eventually want to turn the whore car into an ol' supercar, which should prove to be a lot of fun!

I looked at your build and all your picks. It looks awesome!!! Super great!

 

I have just be learning about the L28 and I just put my first one together, kinda practice. I'm going to build a good one soon. I found some good ideas like the l24 crank and rods with the flat tops you have .. It's kinda a high rev short stroker, I think I aquired one by luck. But you might really like that build.

 

Also, why not go ITB with a MS vs the carb. It's about the same price if not cheaper an IMO way better. I ran carbs on two different motors, and with ethnol in the gas it makes tuning your carb a constant project....I'm not a fan.

 

But I'm stoked for your build, it looks great. I'm excited to see more!

Yeah, I've read about these "stroker kits" people have for their Z's. I wanted something more unique and special, so I when I came across Eiji's resume and what he can offer; I was in love.

 

The thing about the carbs is very personal for me. As I've mentioned before, I am no veteran of building motors. This is my first involvement in a build. I also have no experience with Weber carbs, let alone three of them. The reason I insist on having them, despite some members advising that I don't due to their complexity, is because I grew up loving them. One of my favorite cars from childhood is the 1962 Ferrari 250 GTO. To me, cars just don't get better than that. When I first saw a 250 start-up in person, my ears melted to the sound of the carbs...all six of them! I've been lucky enough to have been in contact with many GTO's since then, and their sound is by far my favorite thing about the car. In fact, the GTO is what led me to fall in love with Z's. To me, it's the Japanese GTO. It has the styling and definitely has the performance capability....but it doesn't have the engine. That's the whole reason why I'm doing this build to begin with...a super car needs a super car engine, which is what my Z is getting. Why the Weber carbs? Because those are the same ones the Ferrari's ran on their engines. In short, I want to make my Z a fantasy super car that never really happen. My own Datsun GTO...

 

Sorry for the long and historical reply regarding my adolescent years, haha. But now you know.

Well for sure :-) I don't know anyone who was bummed that their motor sounded awesome.

 

I actually really like the old ferrari sound. I just got an old abarth exhaust for my Z because on a good motor they sound awesome. I was kinda surprized when I got it but the pipe at its largest is 44mm or 1.8". It also has a lot of restrictions, like poor bends and serious stenoses in the resistors. I'm going to run it as is. If it sucks I'll just run a dual abarth, which will probably happen. I'll post a sound clip when it's running.

 

I have been reading a lot about itb's. I think they sound awesom as well, I plan to run them when I get a MS working. I have been looking at building them vs buying them. You can get a good set up for around 1000-1500, maybe a litte less. I figure you can build a dcoe spaced one for about $500.

 

It will be awesome to see your motor run. Thoes pistons are sweet. That company makes valves that sound pretty awesome too.

I noticed that you say that this build is around final cost $12k. If you don't mind me asking what is all included in this final cost. Internals, machining, shipping etc. .I'm new to this as well (have my 72 240z shell was a wedding gift since july 2013,slowly but surely) previously wanting to go the sr20det route. I was now given a N42 block. And now thinking I should go from there. And honestly I sooooooo feel you on that Ferrari sound.

Also what transmission are you planning to run. I've heard nothing but great things about Datsun Spirit and his commitment to excellence. Truly very compelling. Great build.

 

Hey bud!

 

Yeah, the final cost of the build will be around $11-12K. I got my engine back from Eiji about a week or two ago, so it's currently sitting in the garage. So far, I have over $8K invested into it, but I still need the carbs, ignition system and a couple of other things...should cost around $11-12K when finished.

 

Basically, I went for his Stage III package: https://datsunspirit.com/stage-iii/

 

 Some of the extra stuff I got:

 

- New Rocker Arms

- Adjustable Cam Timing Sprocket

- Zinc Plated Dipstick

- A 9lbs Flywheel

- New Crank Pulley

- New Thermo Housing Kit

- Shipping (There and back again)

 

Then you have the base stuff:

 

- Stage III Engine Build

 * 89mm Kameari Pistons + H-Beam Rods + New Crank (3.0L Setup) + Head Work (New Cam has .290 Dur/.490 Lift) = Rod/Stroke Ration: 3.53

 

- Triple Weber 45DCOE's with Kameari Intake (Haven't gotten this yet)

 

- Currently thinking about getting a MSD Racing ignition system

 

I'm also going with a 5-Speed from the ZX. If I'm not mistaking, it looks really familiar....looks a lot like a T5....

 

Eiji Hosomi at DSI is a genius, to say the least. A bit inpatient at times (As a newcomer to this L-Series engines, I could tell I was stretching his patience quite a lot!) but he really knows what he's doing. Mind you, I believe in his talent so much that I actually ended up going over my budget...by 100%. He's that good, haha. Also, the idea of having a L-Series motor built the "Japanese Way" with their incredible know-how and attention to detail really appealed to me. As Eiji told me; "we only do L-engine and I drive L-engine cars every day, and we think about L-engines day in day out and all the time. I doubt they (or others) can say the same."

so when do the youtube vid's come out?

 

=)

 

Haha, as soon as I get the funds ready to finish the build! I'm already way above my budget as it is...and I'm currently working and going to school, so the build has since slowed a bit.

Once she's up and running, you guys will be the first to know, haha.

 

This is the only pic I've taken, right as she landed back home:

Datsun Spirit is 10 minutes from my house.  I have already talked to Eiji about doing a STR 1 on my spare L28 but that price!  I am new to the L-series and I guess the sticker shock of these motors has not sunk in.

 

Do you feel that using Eiji's motors helps increase and hold the value of the 240z?
