Hi I have a classic Impreza with a sti v4 engine it unfortunately big hole in block now, I have a ej20 closed deck block I’m wanting a 2.1 stroker kit on it and was wondering who’s the best to build these types of engines with stoker kits etc preferably on Scotland us I’m up in Inverness but can easy be sent down to England thanks
I went with Andy Williams
i received best advises from fbtuning
I asked slowboy racing ,chevron, asperformance,tdr
enginetuner just sent me price with no spec
about build depends how many horses You are after,mine 2.1 jdm sti just being done 7.2k build plus injectors.
think up to 550 horses maybe a little less semi closed deck is fine ,over that You need closed deck inserts or closed deck block
build with forged pistons,bridgeway rods 11mm studs etc costs 4.5k plus engine in out
i added 14mm studs ,supertech valves,rcm pulleys,rcm manifold spacers
rcm rods are plus 800
stronger cambelt is extra to
if You need heads work thats extra
and depends from Your bhp target You could need cams,fuel system,clutch,aos ,engine oil cooler,bigger intercooler ,turbo ,ecu,coolant pipes ,oil pipes,3 port ,4 bar map sensor
mine recent build

That looks ace mate I was contacting scooby clinic but couldn’t get a price off them is that Andy Williams under a company name or just Andy Williams and where is he based thanks I’ll contact a few you mentioned also I do have have a lot of extra/upgraded stuff from old engine I’m planning to use intercollegiate turbo eve etc so I’ll be saving that way
Williams racing Ltd but best is to contact with flat4performance they base in north Wales,they remove and fit engine for Andy. My 2nd choice would be asperformance-stockcar here. It will take 8-12 weeks depends how busy they are.
For example my rods are bolted with arp2000 bolts but I could use arp625's .
Nothing wrong with 2000 , for my build this are fine but other ones are stronger maybe better for 550 horses target.

TDR (Thwaites Development Racing) in Warwick would get my vote, they have done a lot of work for people on here, they rebuilt one of my own engines recently and they are superb to deal with.

They’ve said they have loads of different options so when they receive everything they are going to guide me through all the options and go from there they said expect to spend about 6k anyway send a deposit they crack on and pay the rest when finished, I’m hoping to get everything sent down in next week or 2 so I’ll update once all sorted and got go ahead for my option
Thats Your money ,i would like to know price for build and for parts before any work, especially with them.
yes once I’ve decided what to go for they’ll give me a quote then take a deposit and start it, how’d you especially with them? Seem to have good reputation and reviews
They are,
I would ask for quote before sending them engine
If You have engine out send it to asperformance for them to fit closed deck inserts when they will built it.

okay will do he said before I’d probably looking at about 5k+vat but wouldn’t know 100% till saw everything was looking at as performance reviews then seem really good especially with Subarus as well, I have a closed deck block and engine out on pallet now was just kind of waiting for my other toy to sell and deciding where to go few people pointed me in direction of scooby clinic, how long did it take them to build yours?
As mentioned above in my first post mine has been done by Andy Williams( took him 3 weeks) as my engine was in a car-removed by flat4performance.
If my engine will be out of car I will send it to Andy or asperformance.
If it's closed deck You do not need inserts thats a bonus.
First set in mind Your bhp target and turbo.
2.1 build for 550 horses will costs 7.2k with 14mm studs ,bw rods supertech valves,forged pistons,2.5l crank,rcm termal spacers and in my case oem jdm heads with oem cams,oem cambelt ,rcm gaskets,rcm pulleys.
Injectors-as performance 1000cc bosch ones,fuel pump,aos,baffle plate,oil cooler are extra but if You find build from good builder cheaper You could save money for those extra parts.
550+ build needs
better rods 800 quid more ,maybe high grip cambelt kit ,cams +1k ,adjustable pulleys 200 more
build with just forged pistons,11mm studs,rcm gaskets will cost 4.5k but 14mm studs costs not much more,and with higher revs You could have valve float due to oem springs ,i just went with full kit (£1k more) but You can add just stronger springs.
we always supply costs / options up front and the only thing that can't be done prior to inspection / strip is of course assess any damage and what is re-useable...........

ah okay that would be much more helpful, okay if I pop you a message ?
best to email the office direct for best response...........
just to add using +1mm oversize valves in std Subaru heads achieves nothing apart from extra cost due to the 'shrouding' of the factory castings........
