Yeah im very curious too. Are the heads better flowing? I also figured the cylinder walls are thicker so a stronger block? But anyways I am definitely going to take it slow on this build. Boosting it will be alot like a science experiment while I record results lol

I'm not to sure on that. The cylinder wall are definitely thicker but again I'm not sure. My current EJ20e is currently at 323,000 km and with no leaks and doesn't burn oil. Hopefully you have got one similar to mine.

Hey! I'm with you on the ej20e.

I have had mine installed since December of last year... no issues so far.
I'm very interested in you boosting your car as well, because I may end up going that route too.

I originally had an ej25. Went down in size for reliability and price.

I compiled all the information on this thread:
JDM NA EJ20 Swap Megathread

(I need to update that with the pictures I took

Also, I believe there are only 2 style of crank sprockets. Either the one with 3 timing teeth or with a whole bunch of them. Mine were different, so I swapped. It's pretty obvious if they are different or not.

Well, I finally had a little time after work to work on the ej20 and I got it sripped down to where I needed it to be. Just gotta get the timing belt ordered and clutch and I can put her in!


Also I am probably gonna sell this manifold here if anyone wants it. I'll include the PS pump and AC Compressor for a good price!

One more thing, Im also trying to wire my new foglights but I cant find where the relay goes I was told a pink plug but Ive looked everywhere does anyone have any pics of where it may be? The relay I got looks like this

I am under the impression that the fog relay (at least the stock one that's wired to the switches in the dash) is in fuse box in the engine bay. There are more relays there that look to be the same type. Not 100% on that though.

Nice car, I wish I was at a point to be boosting mine right now

The timing belt tensioner looks... strange.

Can you get a better picture/angle? Is it just me, or is it broken?


Wait... I just realized... we have different engines.

I have an ej203 (THREE)... The intake bolts are staggered on mine, and yours are not.
...which I guess also explains why the timing belt tensioner looks so different.

Yeah its the hydraulic style. I believe the ej203 is a phase 2 engine.
