Built EJ-DE


#1

Has anyone here done any internal upgrades on an EJ-DE. I kinda want to take my Cuore (The Curry Cruiser) of the road and learn how to work on it and use it as a learning platform in the long run. In saying that I would really like to turbo it but due to Green P plates, I won’t be able to drive it anytime soon. So any info on building an EJDE to withstand 200+hp would be greatly appreciated.

I know you’ve asked about internals, however, what you are going to do with it will have quite a bearing, as will the fuel and ignition control your intend to use. Road car or drag car will only see max power for fleeting seconds, and you’ll want that big hp. Hill climb, khanacross or circuit you’ll want a broader spread of power and torque. Plus these forms of racing require much more care/quality since it will see sustained rpm. My na ej-de saw 79-80hp with a few mods, cam timing was really important as was lots of detailing of all inlet and exhaust tracts. While I have stalled on building a good bottom end the plan is to use GSXR600 OS pistons, Argo custom rods, a lightened crank, much much bigger cam, Triumph motorcycle triple throttle body (choked down in size), an Autronic SM2 ECU, big head bolts, the current 2.5kg flywheel and Ferrea valves. It should be about 1100cc and 13.5:1 comp. In the comp that I do going turbo puts it up a class as that means x1.7 in capacity and also you are suppose to carry more weight. A reliable 200hp is, in my opinion even without taking and ecu into account, going to be well over $5000. For the turbo route expect a lot more unless you can fabricate your own manifolds. Then you’ll need a good clutch and PP. Mine was $800 and good for 300hp. 200hp will need a lsd, the centre is $1000 not fitted. Don’t let me turn you off, but do plan.

Yes, @Mr_Gormsby, you’re off topic :slight_smile:
He isn’t asking for your elaborate plans :stuck_out_tongue:

turbo is great cheap power

Nice looking ride @Josen_Reji :wink:
You have a few options
If you have fiddle fingers to build, then yes, there are 3rd party parts to mod these for turbo
We don’t have the p plates thing so I don’t understand that one
But basically you seem to be saying that you’ve got time on your hands to do this

A lot of the aftermarket brands do parts for them
Malaysian parts are cheapest - keep in mind there’s a valid reason for that

Easier would be to put in k3vet from the yrv and take it from there
I think even a reasonably stock vet is an awesome package to get yourself in trouble with :slight_smile:
emanage piggy back set up by a good tuner or a link computer is going to be needed basically straight away
I have the wiring info to do conversion harnesses from the L7 loom to k3 and for link computer if you want one at some stage

My vote is for k3 conversion but that’s more time and work in the moving engines part than the splitting engines and looking in their guts type part

I saw a few apparently quick turbo L7’s in Japan when i was there a couple of years ago - so it’s for sure a go though

He asked about a “built ej” and I assume licence wise that could be driven legally as opposed to waiting two years before having an open lic. But I get what you said. My point is you won’t get 200hp on the cheap, 130 with a turbo, maybe, which is an awful lot for an L700. I completely agree on the K3VE. For a P plate driver, you learn a heap doing it , get it on the road and it’d be damn well quicker than a built ejde na

@Mr_Gormsby i’m a bit hard on you cause i kinda like you sorry :stuck_out_tongue:

agree with you
big thing with the k3 i reckon is the usable torque
especially in turbo version

there is a lure to building an engine which i appreciate
but i’ve spent a lot of money modifying when i should have “hot-rodded” it as my dad calls it
then since coming to this conclusion, i’ve had a couple of great cars that had basically modded engines transplanted from heavier cars that have worked so well, that I’m totally into the idea now
not new thinking globally -but a revelation to me

which is why i’m so in love with the k3 conversions
can i say it any other way?

in saying that, i reckon an ej-de with a reground cam, header, nice exhaust and maybe slightly fiddled gear ratio’s to closen it all up , matched with some tasty but modestly priced suspension would be a floopin sweet curry cruiser! [and i’ll confess is something i’m working on at the moment :stuck_out_tongue:]

which i’ll credit going back to your original comment of [as i’ve ready into it] having a think about what you want out of it having a massive bearing on what you should or could do with it

Be as hard as you like with the constructive criticism. It’s healthy and makes us all think.

Joesn, sorry that we’ve rail roaded things here.

The K3VE non-turbo in a L700 makes for an amazing car that you would enjoy. They are damn fast and fantastic to drive everyday (I only drove one a little bit a few times). I would thought do a lighter flywheel. Doing this would be a great start in “learning how to work on it”. 200hp from it is realistic and you’d get that at a fraction of the cost it would take on a EJ and would be much more reliable as a drag or street car. Jono Muir has gone the “fully built” EJ-DE in an L700. He’s done most of the fabrication himself - beautiful work the like of which is beyond my skills. It’s a street and track build, however, he’s currently having headgasket issues and had to pull block out to drill and tap for big head bolts (Nissan VG30E ones cut down). If you look on FB and search for his name you’ll get more pics

as they say, power isn’t cheap, especially when you are talking 4-5 times what the motor is designed to handle. While on your P’s, i would look at going an N/A screamer with higher compression, extractors and exhaust if you really want to learn about them, and really unless you get an aftermarket standalone ecu, you won’t get the best performance from any upgrades even basic ones. Power is nice but too much and other things will break and require expensive upgrades to handle said power, ie clutches, gearboxes driveshafts etc. Pretty sure it was @Mr_Gormsby mentioning he has seen 140 odd hp on stock EJ internals, but alot will do with tune etc as said.

That turbo EJ was pretty much an on and off switch. It broke a lot of gearboxes and axles. The TD05 on it may have been too big.
