Question Sign in if you have ej257 long block with ej205 intake parts

ok I am seriously considering a ej257 swap with a ej205 intake parts. Yet I don't hear much about people running this setup.

So if you have one or know plenty about this setup and fill me in on thoughts of running this setup. Yes I know there will be no avcs, good / bad?

Going to run vf30 for now and maybe something larger later. Also considering a few mods to avoid oil starvation. Any suggestions on the best setup for that with this engine. There seems to be a lot of thoughts about what's best.

Oh will I need to change injectors? I currently have a cobb shelf map vf30 setup.

I understand there will be some vacuum line changes. Can you guys fill me in?

If I am missing anything let me know.
thanx

the intake is exactly the same otherwise.

It's funny, I'm contemplating something like this too. I have new 545 top feed injectors and TGV deletes and a 2.5 liter STI motor. I was hoping I can bolt the pretty manifold right on top of my existing 2.0 TGV's. I've noticed the STI's moved the FPR under the manifold. I wonder if using the 2.0 fuel setup would be a step backwards from a fuel distribution standpoint.

What kind of camshafts are you using that are able to utilize the stock valves? I would seriously think about upgrading those springs.

It's a proven setup that works well and has been done many times before. If you are going to do it, get STI cams for the stock heads, 2.5L head gaskets and use your intake manifold.

I have always called it a hybrid swap.

FYI, other than the throttle body mount area being different, the 2.5L intake manifold and 2.0L intake manifold are identical. As are the TGVs (well, other than the injector style, therefor the injector mouting holes)

i ran a ej257 with sotck intake mani,tb, engine harness, and tgv from a 02 wrx...it ran great. I used bc 272 cams. I only ran it for a few weeks due to the fact that my rings werent seating correctly so i pulled it out and i am going to install 100mm pistons. Just make sure if you have 05 and up you get the cosworth cam sensor adapter bracket. The 257 runs 2 sensors in the back where as the the wrx has one in the front that you need the bracket to mount to the heads.

Well I was corrected on another thread. Yet there is no name for this swap.

If I had to choose a name I would say hybrid long block swap.

Cool thanx for that. I remeber reading that some where once. Yet can't remember where. What mfg makes the conversion parts?

From my searching I found the link from Element Tuning

http://elementtuning.com/technical/ej25_install.htm

Also found that some of the info about the cam possition sensor is wrong. The 04 have that spot they list on the website. Yet 05+ don't. Yet Gruppe-S might have made one. Yet so see any thing about them making this part.

So this is my update at this point. Also looking into the Element Tuning did this conversion and ran a vf30 on hydra = 311 whp. Yet not sure I want to run hydra.

In the process right now of installing a 06 sti lb with my 02 pnp intake manifold tb, and tgv deletes from Grimmspeed, also his(Grimm's) pnp exhaust manifold with x-over pipe. I will be using the Cosworth cam sensor bracket(this is what Gruppe-s sells and is on back order, unless you buy directly from Cosworth). Right now I will be running a pnp vf22 until funds come available for a Green or preferably a sz49. The avcs will not work of course right now...but if you by a jdm v7 ecu it can be open source tuned with the avcs. Unless you want to spend your money on a used Hydra. The guy that will be tuning my car said he could tune around the AVCS, of course spool up will be faster with AVCS but he said I wouldn't be missing it right now.

WOW mis-information in this thread. Use the search term 257 hybrid. what this means is using the sti 2.5 shortblock with 2.0 heads and other head components for the 2.0. The combination works well when built right.

You dont need any stupid cam position sensor if you are using the US wrx 2.0 heads.

Yea but thats not what this thread is about.

This thread is about the long block hybrid. Using the 2.5L sti heads and block. Just with no avcs and 2.0L intake and tgv's. So the info is not incorrect.

Well, I thought it was about using the 2.5L long block WITH AVCS and 2.0 intake parts. That's what I'm doing anyway. Basically a setup like the 07 STI's with their top feed injectors.
