Default Building a ej22t with 207 big port

The wife is building her car and we got everything pretty much figured but we are looking for more input on her motor before we say yes to machine shop

Ej22 bored to a 2.35L
-AEBS sleeves
-paulerx rods(or would carrillos be a better pick?)
-JE pistons
-oem 79MM 2011+crank(Block is machined for center and rear thrust)
-King bearings
-11mm or 12mm studs?
-arp everything basicly(But i've read that it distorts the block some times)



Ej207 V7 big port heads
-Ported over more
-1mm over valves
-BC or GSC cams?(i've heard troubles with gsc lately)
-valves and spring set up(suggestions)
-Single avcs(intake side)


She is definitely open for ideas.


Shes running a compound turbo set up with a s366 an s480. fuel system is covered and using LINK ecu G4+ with ethanol sensor(car will mainly run on e85, apart from going to shows in town) Suspenion set up is basic coil overs ith whiteline everything but we are in talks at getting a full TSS set up, Brakes are Brembos all around with stoptech rotors and pads, We also have wilwoods available to us.


Purpose of this car is 1/4 mile and little street time

I always tell people to get a plateau hone when they hone the cylinders. This basically smoothes out the bores. This will cut down on friction. And don't worry, the rings will still seat just fine.

Also not a bad idea to polish the crank journals and maybe your cams as well.

Have you considered o-rings for the block and heads? May not be a bad idea since you are compounding boost.

On a sidenote, is this a true compound system like a diesel truck would run where they both constantly feed eachother? Or is this just a sequential setup where one spools quickly then diverts the air to the larger turbo?

Nevin- We have looked into o ringing. Also talked to larrys about doing the machine work for us. He did mention the same as you did about the bore.

This is a compound set up as you have stated sequential is a totally different set up

Awesome on all accounts! The only other thing I would look into is some high tech coating stuff. Have you considered wpc treatment? Its basically much smaller sized bead blasting. It improves oiling quite a bit and hardens surfaces a fair amount too. Wouldn't be a bad idea for a high rev motor.

And I'm glad youre doing a true compound setup. The idea has intrigued me for years. Just out of my budget. Hahah

And people these days tend to brag about having compounds but they really just have sequential. So I just had to ask for myself!

No, shes done all the welding the wife has and tons of research. I will pass on the WPC treatment for her to look into.

if you wanna see what shes doing and parts being used. Tinytank_wrx is her facebook page.
