Hey Fuji, have you ever seen somebody use a 81mm Crank in a 2.0L?
wouldn't this technically be a 2.2 if a 81mm was used? and wouldn't there also be a concern about the piston skirting colliding with the case?

What would be a good length rod to use to prevent side loading on such a long stroke? and would you need custom pistons to use a proper long rod? or could you get away using a standard 92mm piston with just a longer rod?

thanks!

I have not seen that setup but I have pondered it. Expensive crank though. Custom Pistons would have to be used. Use standard length rods but have the compression height made to compensate the longer stroke. The skirts of the pistons can be made with longer shirts but would have to be made with clearance for the main supports at the bottom of the block case.

The skirt should look something like the stock ej22t on the right.

Personally I don't see the point of that setup. I think there's a reason you don't see it around much.

Well if you could afford it,

It might be beneficial if you could try it, to have the long stroke of the 81mm give you good torque, and the small diameter of the 2.0L to still maintain high revs?

Fuji would it be possible to run this setup to reach 8-9k and run it at 9:5:1?

Have the internals balanced and have a turbo that will still make power up there it is possible. The power band will just be different.might come as close as a 2.5L.

If you know what kind of a power band you want, you can build it. I usually just tell guys to go with the 2.5L if they really want torque. Simple and cost effective. The 2L guys I give them the stroker 79mm crank option.

You can build a 2.5L to rev to 9000rpms. I would do that than the 81mm stroker EJ20. As long as you have the turbo to keep going. Of course the head stuff too.

Ah yes heads, leads me to my next question, I've read through this thread a couple times now, and all the different chamber cc's and bore matching,

Fuji would the v3/v4 s20 heads be the most superior in the 2.0l lineup? As for flow modification and chamber cc's? I've seen great results from these heads.

But.. I've read lots about the EJ207 heads being some of the better ones produced, I'm looking to stay away from AVCS, and I've heard of guys blocking them off on the 207's. Which would be the best route to go in your opinion?

Lastly, benefits of JDM over USDM? There's lots of threads on it, I'd just like the quick answer, again, heard mixed opinions, and can they be mixed and matched with USDM blocks?

I appreciate it.

The ver3/4 are phase 1 heads. You just have know that means phase 1 manifold or custom. If you plan to go stand alone ecu, I have no problem with that. I just warn people that heads/ecu/harness goes together.

The EJ207 heads intake ports start further away from the block. This results in less of a turn on the floor at the short turn compared to the EJ20K heads. Port sizes are similar as well as shape; D shaped with the splitter i.e. B16 honda head.

You can pick up non-avcs big port phase 2 heads. They are on ver5/6 Impreza Wrx/STi, Forester turbo, uk Impreza GT EJ205 engine.

The JDM big port heads have the advantage of not needing much work to get flow out of them because they already start off flowing a good amount of air. The USDM heads are small port heads and require some work to get them to flow the same or more. The JDM heads have a raised floor whereas the USDM have a straight shot port from entry to valve seat.

You can use JDM heads on USDM blocks no problem. Match the chambers and get the right cams and such to go with the heads if you are planning to use AVCS.

Hi Fuji K,

regarding 2.35 Stroked 2.2L build are there any OTS pistons to get 8.5:1 CR and proper compression height assuming I will be using EJ255 (D25) heads?
Also I wonder if I should sleeve the block or it will hold 30 psi of boost made by GTX3076R 1.06 A/R Tial SS? I'm asking because regular GT3076r blew the stock sleeve (2 cyl) on my EJ255 block with just 23 psi of boost ...

there are not, which is why i get them custom made. are you using the EJ22T or EJ22 NA? I wouldn't sleeve the 22T unless i had to because of damaged bores. The EJ22 NA I would since it's an open deck.

I've seen lots of guys sleeve 22T's. Seems to produce good results.

But also I've heard that the mains are weak on the 22T and sleeving can cause cooling issues.

Someone correct me if I'm wrong..

Well I don't have the block yet but I'm planning to buy EJ22T.
I also have EJ20 CDB sitting in my garage not sure which model but it's of a JDM WRX.
Now I'm not certain if it's worth to get rare EJ22T and sleeve it to run 2.35l or just grab my EJ20 CDB and do the same with it.
As for the sleeves I wouldn't sleeve the block but I'm afraid even CDB won't handle 30 psi of GTX3076 boost.

I believe you have a V1 ej20 block if it is closed deck. I think that is a pretty rare block in itself if it really is.

Hey Fuji, I have an ej20k and I am debating my options in the future. I would like to have a built engine. I am not worried about the stock bearings but in the future I want to be pushing the 350-400 mark and don't think that the stock block will be happy for long.

I would like to keep the high rev of 8k so my thoughts were getting an ej22t and building that and using the 20k heads. I want to have some more low end power but know I won't get it unless I go 2.5. I would rather not lose the top end so was thinking the ej22t or stroking the 20k or even stroking 22t. Have any insight or thoughts? Thanks!

if you plan to sleeve a 22T and stroke it, just grab an ej257/255 and sleeve that. reason being is the crank. The 257/255 are phase 2 and you just run the 79mm crank. With the 22t you need to run the phase 1 or modified phase 2, which i don't like doing unless it's an auto. Really a stroked 22t is like a small bore 2.5 L.

a destroked 2.5L block is pretty much like the 22t. That will work for you if you need the power to be in the upper revs.

Still better to go with a destroked 2.5 even though it is a semi-closed deck compared to a 2.2 or stroked 2.2?

Lol select your turbo first.

FuJi K-san are you willing to share exact pistons specs needed to run 2.35 setup on EJ20/EJ22? I've heard Wiseco have weak c-clips so I think I might want to order a set of custom pistons from JE or CP.

I just saw a closed deck EJ20 yesterday. Does anyone know what the stamped number is in the bottom left hand corner of the case halves show in the middle pic below? Is it a serial number or something? I think the one I saw yesterday said "0351" or something else in the 300 range.

which crank? it's basically the compression height that changes, and then given the combustion chamber cc, the piston manufacturer can size the dish to your desired compression ratio.

Wiseco now uses like oem if not the same c-clips for the piston wrist pin.
