The cost starts at £2050 inc vat for the built short block, plus the machining cost for the CDB rear thrust, now re-priced at £143.75 inc vat.
The build includes Wiseco pistons, K1 H beam rods, a new 2.5 crank and Cosworth or ACL Race engine bearings.

The 2.1 stroker uses a 2.5 crank and longer rods to achieve the additional 100cc capacity.

Can't argue with that, although the S-CDB is good for well over 450 bhp if built properly. The 2.5 crank has a longer stroke, giving a greater swept volume for a given bore. The practical result is better spool up and more torque.

I spoke to Steve Simpson who maps my car , and has quoted figures of about 315hp and 680nm torque going the 2.5 route , as it needs more air at the top end compared to a 2.0 so will loose more boost due to the restrictor , the 2.0 would have slightly higher HP , I'm also running a 34mm restrictor
Cheers Ian

I have just driven back from Enginetuner after picking my stroker short block and reworked heads up and thought ill mention what a great bunch of blokes work there. Im sure they will get fed up with me picking there brains in the coming months when i put it all back together. Happy new year

hi alan, i have a version 2 sti ra with the cdb and was wondering if could rebuild if for me. the heads have a little rattle to them but i think the bottom end is ok. im intrested in the 2.1 stroker with rear thrust conversion forged pistons rods and wot not. im not looking for big power just reliability and piece of mind. if i were to send you two full engines heads an all (cdb's) and recive one in return would this make the price cheaper for me

Can't beat a plug and play! Simtek available at a grand supplied fitted and mapped and comes with loads of advantages. The PP is designed for a standard set up only.

Alan,
Just testing the waters here but what would I be looking at for a 2.1 CDB supply and fit to a 2002 WRX with either my existing heads ported and fast road cam fitted, or a set of AVCS Sti heads and cams fitted with appropiate ECU changes (Simtek I guess). I already have a 3' Milltek system, decat uppipe, APS SR40 turbo, STI TMIC, pink injectors and Ecutek map. I will have replaced the box with a 6speed before the car gets to you!

That includes a CDB, fully stripped, rear thrust machined and chemically cleaned. Bored with honed to fit Wiseco pistons and K1 H beam rods, with a new 79mm nitrided crank. We use Cosworth engine bearings head gaskets and sump baffle plate, RCM oil pump and ARP head stud kit. We use stress plates for boring and honing. We fully overhaul the heads including guides and we fully balance the assemblies. The engine is painted silver. We clean the engine bay when the engine is out.
All work is carried out in our own workshop and machine shop. I personally run the car for the first 50 miles. We change the oil/filter again at this point.
Total £4867 inc vat.
We can flow the heads, but I wouldn't be making a deal of that at this projected power level, and I also wouldn't be recommending a cam change.
The stroker conversion will compliment your SR40 turbo, improving the spool and torque, and I wouldn't want to lose any of that by shifting the overlap. In any event, your top mount will be the top limit, and you'll find the turbo will fit the 400 bhp range just fine. 650 injectors I'd say.
We can supply and map a Simtek for £1233.75 inc vat
Hope all that helps!

Cheers for the info Alan, I'm not planning on keeping the TMIC or Turbo indefinately long term would be a bigger turbo and FMIC to aim for a solid 450 to 500. Would the proce be the same if I supplied a set of sti avcs heads with the car (in the boot)?
What age heads should I be looking at I know the Blob ones should be ok 2003/4/5 any others ok?

I was thinking of going AVCS to try and improve the spool, I only have std wrx heads and cams. I was thinking I could pick up a set of STI heads for around £700 then it's only the cost of the aftermarket ECU (Solaris/Simtek) to consider as I was thinking the cost of fitting a second hand set of heads would be tha same as refitting mine therefore in the long run saving money? In fact it would give me a long engine to get rid of/sell on?

The WRX uses tumble valves, which doesn't go with the AVCS loom. Etc...
