I have a cdb but needs a re-bore, its pretty bad on just the one cylinder. How much can you take out when re boring? the crank seems ok, it was from a version 1/2 ra. Alan was thinking of sending it down to you for a forged rebuild.

 

We wouldn't be worried with a CDB at plus 1mm. We'd need to see it to tell if it's a goer really. Come on down!

 

Thanks Alan, no good then, can you replace the one cylinder? would be a shame to chuck it.

 

If the mark in the bore is more than 1mm deep, it's not much good unless you liner it. I have heard of people just putting a liner in the one bore, but I'm strangely averse to that! We've had mixed results with linered blocks in the past.
What's your projected power output? we often use Semi CDB's from the new age, safe for 450 plus for sure!

 

highly recommend this engine to anyone thinking about it, picked mine up on saturday and it drives like a dream....i would suggest sending your car down to alan and the team and letting them do the business, it certainly worked for me and once martyn worked his magic with the mapping the results speak for themselves - the car is superb, great job

alan has my block ready for shipping!!!!
cant wait to get this badboy under the bonnet!!!

 

It's all in the box ready to go. I think you'll know when it arrives! Cardboard City Arizona... TNT say three working days from tomorrow.

 

You cant build them fast enough.

 

i'm not sure about that steve, mines plenty fast enough lol

 

I have a mint CDB from a version 4 ra. Would like a 600-650 bhp engine with high 500 ft/lb. What would you recommend and what sort of price am I looking at. Pm me if you prefer. Thanks

 

Hi Alan,

I had a PM a while back from you stating the price for the 2.1 drive in and out. Very tempting price but i find myself interested in a 2.5.

What would be the price for drive in and out for a fully forged 2.5, bearing in mind i only have an EJ20 block? Looking to run upto 600 hp

Cheers,
Tom

 

you'd be best giving alan a fone mate so he can go through the options with you, it should be fresh in his mind tho as theyve just done what u are after with my car

scott

 

If you want to go that far, you could use our 2.1 stroker with a GT35/42R with confidence.
A high torque figure would need a 2.5 engine, then you have the worry of a less than confidence inspiring block. Just ask Scott what he thinks of the 2.1 option!

 

Hi Tom

You'd have to sell the block and start with an EJ257. The 2.5 is fine up until the point where we all start worrying about them, then it's your choice. I tend to feel that a standard block is probably stronger than folklore would suggest, we have never suffered a block failure from one. However 600 bhp and above is available from an EJ20 CDB, and with less sleepless nights. It's the reason we took off in the stroker direction.

 

ps thanks for your help on the phone today Alan regarding the TypeR.

 

My pleasure mate, hope it helps! If you need anything at all, just give us the word.

 

Would the SCDB i currently have, fitted with the 2.1 stroker hold 550-600 reliably?

What would be the difference in cost between the 2.1 stroker using my current block and then using a SCDB (EJ257) and having that forged? 2.1 cheaper?

 

If we're talking about high power outputs, there isn't anything in it as far as the cost of the components is concerned. It's about how far you want to push your engine.
If you want to run an EJ257, you either trust in the integrity of the block, or you go for a linered or otherwise strengthened option.
If you want to run an EJ20, you at least have the choice of a CDB. I wouldn't say they are bullet proof, but they are much tougher.
We have run standard EJ257 blocks well over 600 bhp, but we're careful to point out the risks involved to those who wish to go there, and we only proceed if they accept that there is a quantifiable failure potential!
There is an argument to say that the S-CDB EJ20 could have better structural integrity than the S-CDB EJ257, but I can't see anybody soon wanting to pay out to test that theory. That's where the problem is! I get asked which block I'd recommend, and the EJ20 and EJ22 CDB's are always going to come out on top.
From where I come from, big engines are always best if all the boxes are ticked, but there are plenty of reasons, depending on turbo choice or car useage for example, for taking a good look at the EJ20 CDB stroker option.

 

i would definitely recommend the 2.1, alan and the team did a great job with mine, very driveable like a normal car with a whole load of power on tap whenever u feel the urge.....

 

Will have to find out one day.

 

So the EJ207 SCDB with the 2.1 stroker kit would be more than sufficient with 500-550hp?

 

I'd be happier with a fully closed deck block no question, although I'd say 500 bhp plus shouldn't be much of a gamble with a well put together semi closed deck. The stroker part of it isn't the issue.
Put it this way, most people who jump out of aeroplanes land perfectly safely!

 

Yeah, but look at what happens when they dont

I'll be in touch soon

 

Look forward to it. We always have the option of a CDB, we have a spare one in stock!
Think of it as a reserve 'chute..

 

Thanks for info Alan.

Could i get the best of both worlds by getting a EJ22 CDB and get it stroked to 2.33 by yourself?

Second question, do you take installments?

 

Alan, Question......

What about the Brian Crower 2.29ltr stroker kit for a 2.0ltr CDB??

 

Yes we do, and when you've paid, you can have the engine!

 

We'd certainly be interested in taking a look at it!

 

Is that even possible from a 2.0L block?

 

thats what i was asking Alan.

What are your thoughts on 2.29ltr from a 2.0 CDB.
