Build my 2.0l EJ207 or 2.2 Stroke it for 400+ whp and high rev???

prokaw875 · 11-23-2009, 09:12 AM

So I'm looking into some possible motor upgrades for my version 8 EJ207 and I have 2 different options that are currently in my mind. Final goal would be to have a high reving, 400+ whp on pump, turbo will most likely be one of the nex twin scroll AVO or Tomei turbos that are supposed to release soon(30R sized?)

First option would be keep the version 8 EJ207 bottom end stock, drop in forged connecting rods, forged pistons, APR head studs, some 272 AVCS cams, port n polish, and call it a day...

OR the other route would be a tomei or cosworth 2.2 stroker all forged(not the $9,000 billet crank kits), and keep the heads stock... Maybe some cams...

Opinions about a good EJ207 build... Cheapest for most reliability and power?

Thanks all

u could do same as the cosworth or tomei 2.2 but use

92.5mm pistons
rods
ej257 crank

thats what i am doing with my ej207

much cheaper, plus its not a real 2.2 its a 2.1 something

Ya I think that would be the same displacement as the Cosworth, Tomei, Jun, HKS... 2.2's because all the 2.2's have a final displacement of 2148...

Thanks for ur opinion... More options people?

Agree. I'm doing this with a 205 right now. Should be epic. With the money you save you can do like I am and get some good head work and some big ass cams.

NITROS · 11-23-2009, 03:43 PM

One can build a pretty reliable block with just stroker pistons with sti rods and crank.

Should be running by Christmas

Hopefully see it at the shootout where I plan to take out Ben in the 39 class this year till I can afford to go with something...larger and twin scroll

Thran · 11-23-2009, 04:24 PM

i am getting my heads worked on, short block is already to go

i am still stuck on the turbo : (

Hyper · 11-23-2009, 05:09 PM

you believe AVO will finally release it?

I went 2.12 route (with the crazy Cosworth $$$ crank

), PnPed heads and in the spring when I have money I will do cams, most likely Tomei Type B AVCS cams

everything balanced with proper oil pump for my tolerances, intend to rev it to 8500 when I have a turbo that will not run out of breath there

luisbwrx · 11-23-2009, 05:37 PM

whats better 272 cams or 280's?

i think 272s should be perfect, 280s will make ur power band go too much to the right

it really depends on what turbo u run and the lift of the cams as well

jason miller · 11-23-2009, 05:51 PM

That's a really vague question with no definitive answer. Every manufacturer makes different lift values for their cams, so they're all different from brand to brand. Also, not a lot of Subie guys are running 280's, so there aren't a lot of results to compare. And finally, it depends on your goals. Longer duration suites higher revs. For example, the stock ej207 cams that are designed to work at 8250 rpm have more duration but less lift than stock ej257 cams that are designed for 7000 rpm. Oh, and bigger cams ideally need headwork to really make use of them.

prokaw875 · 11-23-2009, 10:29 PM

Hyper... If you can please send me a mod list, build details, ect. About your set-up if you have time prokaw875@yahoo.com is my email. And I would imagine 8,500 would be ZERO issue to obtain since bone stock 207 v7+ rev to 8,250 and the guys in japan track stock 207's to 8,500 all day long. Dry sump and go for 9,000+ =)
Thanks dude!

Yes, but you won't be using any of the stock 207 parts.

I'm still trying to learn what bearing clearances and oil pump I should be running. It is hard info to come by around here.

U dont think that a 11mm shimmed pump isnt good enough? i think the clearances are a bigger issue... to be honest

Homemade WRX · 11-24-2009, 09:01 AM

You can always go 83mm stroker crank and make a true 2.2L. It does require some clearance work on the block, much like a 383 stroker in a 350 block.

Hyper · 11-24-2009, 11:22 AM

what clearance work?
we didn't have to do any, using brand new EJ207 block and BC 83mm crank

I love that motor... it's amazing, torquey and revs to the sky

Big_DeWeY · 11-24-2009, 11:36 AM

Yum. How much was that crank? Any dyno charts?

Hyper · 11-24-2009, 11:46 AM

a lot

don't have charts
we are taking it easy since it's running TMIC on a 35r

but it goes

Sorry, should have specified that I clearance for the rod big end. I run Pauters.

BC cranks are actually quite 'affordable'...heck, I can get 5 cut to my specs at $1500 each.
