Our very popular 2.1 stroker engine is now also available with Cosworth pistons!
The exclusive piston design is an addition to our range.
Example; Built short block using a new 79mm crank, Cosworth pistons, K1 rods and ACL Race bearings £2400 inc vat.
Using your donor block, we fully strip and chemically clean, rebore to suit and hone to fit using stress plates. We fully balance the assemblies. The blocks are painted, and presented ready to fit.
We carry out all work under one roof in our own machine shop, the engines being built by the engineers who machine them.
We also trial assemble, calculate and set correct CR.

Aren't they pretty?

During assembly

Enginetuner modifed AVCS head with Cosworth plus 1mm valves.

alan how long or how many miles are thezse pistons good for as i have heard but i am in now way saying this is true that forged piston we only last 50000 miles but to be far 50000 miles is a good length of time for a forged engine running some big bhp

Alan Jeffery

I think most Impreza owners would consider 50,000 miles a result!
The issue wouldn't be how long the piston lasts. It may be the case that some increased bore wear could ultimately result, but certainly compared to some soft OE pistons it's a fair trade.

whats the price difference between these pistons and the normal ones you use on your 2.1 conv....are these a better piston?
I will be ringing in the next couple of days to book my car with you for the 2.1!

Alan
How much are we talking for drive in drive out??

ie: Drop the car off with you and pick it up when all finished, engine, mapping, labour etc etc.

What sort of timescale for all the work to be carried out??

Beat me to the same question

Alan, are the rods used in your stroker kits standard length?

Alan Jeffery

The Cosworth pistons are another £100 inc vat on top of our current price.
We haven't had any issues at all with the Wiseco piston, I just wanted to be able to offer an alternative spec for a number of reasons.
Firstly we are Cosworth dealers, and wanted to be able to offer an all Cosworth engine as much as possible, in view of the quality associated with the brand.
Secondly we wanted to expand the range of options, particularly for con rods, on the basis that we are being asked for more powerful engines by the day!
Thirdly, I like shiny new things, and so do my customers..

Alan Jeffery

We can do a drive in drive out from £4400 inc vat for the above spec. This includes an RCM oil pump, ARP head studs, Cosworth head gaskets and sump baffle and genuine Subaru gaskets and seals. We fully overhaul the heads and set the CR.
We also do the basics, such as jet wash the engine bay etc. We like them to look nice!
Once we get the end of Jan out the way, we're aiming for a four week turn around. We can possibly lend out one of our now famous "courtesy cars" ..
The above would cover the engine build and installation. We'd have to discuss mapping etc first as it's all relative to your personal spec and requirements.
We're available to talk any working day (Mon/Sat) on 01752 345880.

Alan Jeffery

I'll say yes and no!
This is what it's about. In the first instance, we had a supply of pistons to match the stock rods. This supply dried up. We made enquiries and found a supply of the plus 1mm K1 rod, and pistons to match. There is a line of thought that says a plus length rod is a good thing with a stroker. It's about the way the piston rides on the thrust face of the bore during the stroke cycle. We have never had cause to regret that move, having supplied a great number of these engines.
We have chosen to offer an alternative at this stage. The reason is based on the desire for a higher spec rod to accomodate increased rpm and loading. The difference between the standard length rod and the "long rod" is tiny. I figure it wouldn't make much difference in reality.
A fringe benefit is that we can now offer a range of stock length rods to match the Cosworth piston, including the Cosworth offering, which is only available in the stock length. Plus my customers can choose a rod, or make use of their original rods, which will often survive a piston or bearing failure, making our conversion slightly more affordable. These are tough times!

Alan Jeffery

One more thing, we can also supply a Nitrided crank alternative, as well as any choice of head stud, cam kit, head work, you name it.
PM for options?

stunning pics Alan, God I want a 2.1 stroker but cant afford one at present

Alan Jeffery

Of course..

Neil..

iTrader: (35)

Cheers for that Alan.

So do you still do the cheaper option piston to use a std length rod, or is it now just the Cosworth piston?

Neil.

Cam jewellery should be at yours on Monday !

Alan Jeffery

We haven't offered a stock length rod piston option for a while. There's nothing wrong with the Wiseco pistons, it's all about choice!

Alan Jeffery

Hey, no problem!
I'm sat at my laptop right now, even more sausage fingering than usual!
Lizzie said that while I was at work today we had a flood in the utility room caused by a blocked drain backing up the washing machine outlet. The water covered the power supply for the tumble drier and shorted the electrics to half the house. By the time the trip switch had been reset 27 times to figure out what was up prior to discovering the Aussie style flood my desk PC said "sod that" and now refuses to boot up. Hot Damn. I'll get the calculator out in the office tomorrow morning, and we'll see what we can come up with..

Right A.J. will be chatting with Bigarf at the weekend to schedule pulling my engine out in March, so you can turn it around for an April delivery (?)

Regards,

dunx

P.S. What's the extra cost of the nitrided crank option please ?

Alan Jeffery

Better get it here early, we have a busy year on.
I'm working on the prices as it happens, they won't sit still!

Ian

just out of intrest, are the cosworth pistons quiter than the wiseco piston?

Shiny

Alan Jeffery

I wouldn't say either one have a particular problem, not compared to the average tuned Subaru engine.

dunx

iTrader: (3)

Sorry A.J.

Arf and I will pull it out in his workshop...

I will allow you to work your magic...

Then Arf and I will bung it back in !

Thanks,

Alan Jeffery

Being fair here, I'd have to say that as long as you are both adults, what you and Arf get up to in his garage is fine by me..
