My L500

Hi! thought I’d do a overall of my L5 build. Not finished overall though never is a project car truely finished.

I initially started with a base model L5 Mira that had a EF-EL engine, was fun to drive because of the overly high limiter at 8700 though never was able to drive it very long with the 660cc engine. I consistently had issues with the head cracking in the exhaust valve seat and spark plug port, I ended up going through 3 engines and 6 different cylinder heads all with the same issue. I also upgraded the seat to a YRV seat as I picked one of those up to daily while I had engine issues with my main daily. Not very worthwhile as I sat about 5mm off the roof and am only 5’6".

So I decided to go for the popular option which is 989cc EJDE swapping it, I wired it in myself with a standard manual ECU from a L700 handi with no immobiliser. ( I actually have a post on doing that If you need help )

I drove it like that for nearly a year before I had 3rd gear become a second neutral and my clutch destroy itself by shattering apart. My only real option was to go for a stronger gearbox as that’d been my second EF series gearbox and they’re fairly hard to find in good nick in South Aus. The real pain of a job was sorting the front axles, as I was converting to 4x100 PCD at the same time. I ended up making some myself which are still holding up quite fine today even with not easy driving and about 3000km so far.

During this time I picked up a L512s front bar and bonnet.

So I went through converting it to 4x100, started with the rear as it was the easiest at the time, since L700 drums have the exact same rear wheel bearing as L2 through L6 and also share the same brake shoe size, just different PCD.

Then I went through doing the front, though unfortunately didn’t end up grabbing many photos of this during the time.

Ever since doing 4x100 I’ve been daily driving it. Slowly changing things overtime, I initally started with stock 14x5+45 steelies from a M100 sirion with 165/65R14. They were ok, but very heavy and you could feel the weight. I then found some no name 14x6+45 ROH wheels that were painted white and came with okay tires for 50$ on marketplace, so on they went.

They were alright, but still fairly heavy and poked quite far out of the guards aswell as scrubbed quite bad under compression. So I eventually found some OEM Enkei wheels in pretty bad condition but they were cheap.

So quite some time later and all four were looking like this.

I also made some coilovers work for the front so I could tune the handling a bit nicer. Cheap ones from a AE111, worked okay but had very stiff front springs at 9kg. So driving it over Adelaide roads hurt as every bump went straight into your back.

Just recently I’ve swapped the springs on them to 5kg ones with 7kg rear and it handles very well, I’m happy with it for now, though I do need to find better tires. I also recently upgraded both front seats to that of a MA70 Mk3 Supra and redid the door cards. These seats hold me in quite nicely and are still very comfortable.

After that I was able to find a L512 rear bar and mid wing, so on they went aswell. And I’ve been enjoying driving it like this now. Looks great and handles well, fun little car still weighing a little bit heavier than stock at 680kg. With what feels like 35kw at the wheels. I will eventually get around to turbocharging it, though that’ll come in time. Still need to learn how to tune first.

Nice write up and come anlong way since you first got it. In regards to the ef/el heads having cracks exactly where you describe is one of the most common things I have come accross. I have used them time and time again and had no issues what so ever I only ever had 1 head that didn’t have the cracks and that is in my old Move.
Did you actually have issues with them or just found them and thought they were buggered.
I love the supra seats they look confy as!

Ah yeah, the cracks kept making it misfire so always had problems with the EF-ELs. Seats are awesome, like sitting on a couch!

wow you must of had a run of bad luck with them.

Yeah, got quite unlucky. Ah well, when I get around to rebuilding a EJ that’ll be fun. This one is going nicely!

Planning on doing disc rear soon as-well as looking into putting a speeduino on and tuning it N/A as I’ve not tuned anything before and going immediately to forced induction will probably break something.

if want cheap assembled speedy then Nick Hay from Tassie has some and usually cheaper than most places. I have the micro in storage ready to go in. But hadnt got around to it.

Ah yeah! I was either going to go for one of the new Speeduino Dropbear V2’s or go with the STMPRO from nick. Just figure that I might as well go for a reasonable cheap one, If I had the budget I’d look at a Maxxecu mini since they’re around the 1200$ mark with a harness. But a ECU from nick and a good AEM AFR gauge I’m looking at about 850$.

I’m only really looking at hopefully hitting 70kw or 100hp at the wheels, which if I do everything right, I should be able to make on 9-12Psi. Either way, 70kw is over double what it currently feels like and it’s quicker than my friends 7k KE70, so I’ll be happy, only weighs 680kg without a driver.

I know I probably shouldn’t cheap out on the ECU and go with something like the Maxxecu mini, but I figure if I do speeduino I’ll be able to put a write up for others that also do the same. Maybe there’ll be less melted piston stock ECU turbo EJ’s then?

I have a to sort a bit out before all that anyway, currently pings it’s head off even on 98 with octane booster so I reckon it has a lot of carbon on the piston crowns. I’ve ordered a can of Subaru upper cylinder cleaner, hopefully that’ll clear it up. If not it’s head off and a clean and new gasket. But I have All Japan Day in Adelaide coming this month which I’ve entered for so I’m not going to mess with it too much before then.
Though the coming plan after is rear disc which I’ve been collecting bits for already. After that then I’ll be looking into more engine work, brakes come first as then I have more time to test as I daily drive it.

Yeh I got the mini before I got Mr-G’s mira and was purely budget. (all my stuff is usually budget). Otherwise I would have got one of Nicks other ecu’s.
In the past with my old move I had a greddy blue which most people can’t seem to get working right. It took me a long time but I finally worked out why people could not get them to work and I did get it working.
The greddy blue is only a fuel piggy back ecu.
Once working it actually worked very well (on my franken), so I learnt how to tune and dial in fuel adjustments but have never really done spark as yet.

I do have a Speeduino base map file from a former dai member on a hard drive somewhere I can dig out and share when needed so sing out if you want that to help. The car was an L700 ute from SA. You may know him or the car or remember it. I can’t remember the guys name atm.

Have a great time at All Jap day. I have never made it to one as yet. Not sure if I ever will haha.

Ah yeah! very fair, same as me. If I can’t afford stuff I’ll just reverse engineer and make it piece by piece. I have an abundance of scrap metal so if I have the time I usually get around to making things. Would like to pick up a machinist’s apprenticeship sometime as I would enjoy it and am fairly good at what I’ve done so far.

That’d be awesome if you do happen to have that base map, I remember Greg’s L7 ute. it was the ported supercharged EJDE rattle can blue one. He’s also apart of some of the other groups I’m in so I’ll give him a buzz if you can’t find it.

And yeah I figured that style greddy would only be a fuel piggyback, most piggybacks nowadays are just starting to incorporate ignition adjustment aswell. Benefit to the Frank engine was you still had ignition adjustment by the EF-EL dizzy. I figure the EJ should be alright to tune, only thing im a slight bit unsure of is it having 10:1 comp so it’ll melt stuff if I mess up a little.

I’ll probably pick up a kemso 255 copy and possibly find some WRX injectors, I currently have some RB25DET injectors laying around from when I owned a 722cc EF-EL 3 years ago but not quite sure if they’ll fit.

Should be easy enough overall, I was thinking of either going for a stock EFDET turbo kit with the speedy but I might look for a CT9 or VF33 if they’re around and just have a go at making a manifold. And thankyou about AJD, I’ll see how it goes.

You could look for an engine reco apprenticeship also they are incredibly cloe to machiinist. I started one years ago but left as I sold my house and moved from Vic to NSW. Didint find anything after I moved.

I get concerned about the timing on ejde also I figure if you make it more that 5 degree btdc then your winning lol I figure when I got to it I would try bringing it back to 10 btdc and see how they go from there. That was my thoughts anyway. I have used the kemso pumps before with no issue. I have used but not really tried and tested well the osiris (not sure if thats the proper name but how I remember it). It seems to work fine from the minimal I have used.
I think the injectors will fit. I would give them a try (n/a) and see I guess.
