We can now supply a short block stroker, based on your rear thrust 2 litre block.
We specify a new 2.5 crank, with forged rods and pistons, using Cosworth engine bearings. The short block will be prepared and painted, ready to fit for £2050 inc vat.
The result will be strong enough for most applications, including the option of a thrust converted closed deck block, which should be pretty much bullet proof.
Call us for more details!

What make are the rods and pistons and if a closed deck block was to be supplied would the total price be less than quoted

Alan Jeffery

We are using Wossner pistons and H beam rods with ARP bolts.
The closed deck block can be used, but needs converting first for the rear thrust. Roger Clark converted the CDB used in our test car.
The total capacity is variable of course, depending on the block oversize.

Big Bear

What size over bore pistons are avaialble?

Alan Jeffery

In theory any size, although you wouldn't want to thin out the bores too much!

Going 4 400bhp

What sort of power could this block take?

Alan Jeffery

400 bhp would be a doddle.
Using a CDB I would have thought 600 wouldn't be an issue.
The bottom line is the same as any engine, the weakness is at the weakest point. Take care of the small details, and it's surprising what you can get away with.

tempting

black newage

thought you were going 2.5?

jd5217

open to options.

2.5 makes a cracking road car, but i do like to rev and could still use my extg block for the 2.1

2.5 will rev JD Shaun revs to 8000 on his built 2.5, mine revs to 7500.

Looks like a good deal Alan J

jd5217

but how much did Shaun spend on his? lol

I will look into further when I need to as it does depend on finances.

im tempted by this, am just going to see how the next couple of months turn out first

i am a bit confused, the price stated is that using your current block or a cdb if not with a cdb how much would this cost? as i was looking for the 450 mark so if you state the the non cdb is only good for 400 then i will need something more

On another note I have just sold a sti wagon which I was tasked by the new owner to fit a six speed box/brembos etc too and then to take to Alan@ Engine tuner. For a new engine /turbo and simtek etc to be fitted

I was present when the car was finished and have to say what a bit of kit these things are.

Well executed spec on time on budget and how well did the thing rev!!

Be aware in London there is a very clean subtle styled sti wagon that is running a lot more power and punch than you might expect!

Alan and the guys @ Engine tuner thanks for a job well done and an excellent car if I do say so myself..500horse daily driver!



If you havent dealt with Alan before I for one recommend him and his team.

Alan Jeffery

Hi Stevie - Regret slight price increase! the cost of stuff has moved upwards, the Yen and the Dollar prices haven't helped one bit.
The price is for your own rear thrust main block, refurbished. If we have to use a centre thrust main block, there is another £150 for machining the thrust face to fit the new crank. This also includes the CDB. We are running several customers cars at the 450 bhp level on open deck blocks without any bother, it's just one of those things about choice. Given the choice, I'd use a CDB for a 450bhp engine, but it isn't absolutely necessary.

Ok it would be £1800 to build the block correct?

so could you tell me what the cost would be for my p1?

Is my current block open or a closed deck?

And what would the cost be to fit it?

Thanks

And if I chose to use a closed block what would the cost be for the crb?

Alan Jeffery

Your P1 block should have a rear thrust, so wouldn't need any modifying, therefore £1800. I'm actively seeking cdb's, the cost depends on what I have to pay for them! If you're able to get one, we can use that instead, don't forget they also need modifying for the rear thrust.

stevie1982

iTrader: (16)

so if I can use my current block, with the uprated internals what power should this be able to take?
Also what Would be the cost to fit the block?
And I assume you will be replacing the head gaskets and seals etc?

Regards

Alan Jeffery

I don't think anyone would argue with 450 bhp as being pretty safe.
Of course the short block is just that. We can fit it for you, I'd say around £3200 all in, including Cosworth head gaskets, overhauling the heads, cam belt and oils. Other incidentals could include RC oil pump, ARP or Cosworth studs kits, new modine etc. if you choose them. We can detail the motor as well, at a cost of course, also if you choose to.

Ciaran

iTrader: (16)

so if i was to get a knackered short block of the right type you could rebuild it to this spec for 1800?

stevie1982

iTrader: (16)

i assume the oil pump is needed so but can i ask are the stud kits need? what are they used for sorry if that seems stupid but this is all new to me, thanks.
again what is involved in detailing the engine? and at what cost?

so for £3200 you will supply and build with the spec provided in the first post which should run 500bhp safely. can i ask how long you would need the car for?

thanks

Alan Jeffery

As long as the block itself is good, yes!

Alan Jeffery

Stronger head studs allow for more boost more safely. ( They keep the heads on ! )
Detailing depends on you and your budget, we can go from just cleaning, which we do anyway, right up to show quality. If you check the gallery on Alan Jeffery - Engine Tuner you can see a few examples.

To clarify that last statement, We'd say 450 bhp is fine on your original P1 block, but I'd go for a closed deck block if you are after 500 bhp plus and intend to use all of it!

iTrader: (2)

Would it be 3200 for my rather tired uk turbo 2000, just wanted a stronger engine so i can add/change turbo etc etc when funds are available or are there other options

Alan Jeffery

Hi Matt - That sounds about right, but bear in mind we can offer as many options as your imagination can come up with! Just give me your wish list and projected budget, and we'll see what we can offer you.

matttp1

Thanks for the reply, was looking to go forged, not looking for massive power, around 350 , but with the possibilty of more later on down the road, budget about 2k just need to offload our other car then ill know better
