Bit of a update....

 

holy ****!
have you won the lottery?

 

How much would it be if you built it into a CDB supplied by yourselves?

 

We have a couple going right now at £600 inc vat, plus rear thrust machining at £150 inc vat. They are fully refurbished and pristine clean.

 

Me too

 

Anyone thinking of dealing with Alan will not be disappointed a truly honest n genuine person.......

 

I wish lol

 

Thats not really the full picture though is it?
The power rating of any block will also be determined by the internals. In many cases more so than the cc.
Yes there are limitations on the casings but its not really relevent to compare the limitation of a block by saying a EJ22 based 2.35 build engine is good for 700+
Good quality big BHP capable rods in a built EJ20 and lesser quality rods in an EJ22 based 2.35 and see which one makes the most power safely without going pop!

The main advantage has to be spool. EJ22 CDB based 2.35 is a winner because its proved to be reliable at high power levels.

2.1 is popular as it works out only a little more expensive than building a 2.0 but with the added extra cc. And if built into a CDB (which go for ~£300) then thay are very strong assuming good internals used.

I opted for 2.1 CDB myself as the cost was way lower than the CDB EJ22 based 2.35. Even just the bare block its self - £300 v £1100

I think thats the real strength of the 2.1 - It can be built for sensible money with decent internals and easily handle mid 500's with good spool.

Of course they can be made to take more power but at the cost of spool as is always the case when moving up the power band.

All just in my humble opinion of course

 

It's more stroke that aids spool over a overbored engine

 

Nothing wrong with any of those statements.
The other issue is cylinder head flow. We've found for what we'd call a mid range build (450/500 bhp) the 2.1 gives much better overall power figures and revs out very well compared to a 2.5, which is more about torque.

 

When it's finished.....that's good value as what else woul you get for the performance on tap!
Good luck matey

 

It's a very nice project, Gus doesn't appear to have missed much!

 

Wa Wa we Wa
Need a better paying job

 

Bit more of a taster for you

 

I'm not here to bad mouth any Subaru engine builders, and it's not my place to talk about Bigarf's unpleasant experiences... of poorly built 2.5 motors.

But his 650 bhp Enginetuner motor has only needed maintaining despite being leathered to hell and laughing at it !

I suppose you will be astounded that A.J. is currently doing the heads for my 2.1 build.

dunx

P.S. IMHO the cost of the internals is within reason almost identical, the extra costs are in ensuring the structural integrity of the block, EJ22T or pinned 2.5.

P.P.S. A.J. I had a visit from Bez ( Tim B. ) in his 2.5 Engintuner powered Hawkeye last night, he's a very happy chap !

 

On pinned 2.5's?

Show me one. Link?

 

Excellent!

 

Looks brand new? Is that a cleaned block, or new?

 

No it's used

 

We try to make them all like that, inside and out!

 

You have sort of lost me on that reply and why I have been quoted in there.

I was not reffering to anyones car in particular or bad mouthing AJ in any way. I have spoken to Alan on more than one occasion and indeed considered getting him to supply and build my 2.1 stroker until I made a deal with another well known supplier.

Any build is only as good as the components used and the care and expertise taken to build not just the short block but indeed the complete engine and then of course the mapping.

You are moving on to a completely different topic here. I was speaking about how internals are the limiting factor for max safe power and not cc. We only need to look at the RCM gobstopper for that. Its a 2.0 AFAIK.

There are limitations to casings but as Daz says things can be done such as pinning. The limiting factor is still the internals. Clearly all internals are not the same both in ratings and price.

Its very easy to spend silly money on these cars as I'm sure we are all aware LOL, so I try and have a logical approach.
The intended use, planed power figures, planned rev limit etc and budget all need to come into play when selecting engine spec.
If I was to look at building an 800+BHP track only car I would use different internals than if I were looking at building a 500BHP road car and ultimately it would cost more for the higher spec car.

Likewise I would consider which block to use based on what I had to spend. Average price for EJ22T casings is £1,100. A complete 2.1 stroker buit short engine in an EJ20 CDB is about £3,000 all built and ready to fit.
Thats why the 2.1 has proved so popular, Alan him self has put a fair amount of them on the road

Could spend ages going on and on but think I have cleared up what I meant. LOL.

 

With the greatest of respect...

Who would put chocolate pistons into an EJ22T ( apart from Subaru UK ) ?

The bottom line is that all the parts used have to be suitable for the targeted use, and power/torque requirements. BUT the easiest part to break is a 2.5 block... IMHO.

Anyway, I think we are dancing round a handbag now, so I'm off...

dunx

 

Looks amazing- if the kids go to sleep early enough I may put one for sale on ebay to see if I can get enough for a similar build

Slightly off topic, but are there any graphs comparing a 2.0 and 2.1 with the same turbo etc?

 

No issues here - I love a good debate.
Never been much good at Dancing though. 2 left feet.

And I don't disagree with the 2.5 comment for a built engine.
EJ22T or EJ20 CDB all the way. Wish I could justify the extra cost from the 2.1

Peace.

 

Don't have many back to back, as most that arrive are dead before we begin our work. Have a nice example of what a 2.1 can do on a measly TD04, stock injectors, 3 inch exhaust and a topmount though.

Oi Alan, stop lurking and tell me when to send this grubby STI lump down there...

Seriously... when are your guys on holiday ?
As I'd like to be a pedestrian for as short a period as possible

Is it next month, or September ?

Regards,

dunx

 

If anybody is off next month I'll throw a wobbly. Drop it off in two weeks?

 

You not picking it up ?

I'm away with work till 29th. Will see if Bigarf will drag it out whilst I'm away

dunx

P.S. Had a chat with Bez, and his support group last night, he is a very happy lad... they were less happy after 19 hours on the road...

 

Of course I'll fetch it, I thought you wanted to drop in for a visit!
Yes, the chaps had a lousy run down here due to a Focus exiting stage left at 4 in the morning on the A38. They seemed to enjoy the day out apart from that!

 

Dunx I spoke to Bez yesterday he seems well chuffed with his build and excellent numbers cant wait to see it out on sunday.
