Not Again - 2.1 Stroker kit question?
Guys,
I`m looking into the possibility of a new rebuild (2.1 stroker). 400-500 bhp area. I set aside a budget of £4.5k , which from speaking to a few reputable builders can make something out of it.
But trying to get the most for bang for my money i`m looking int stroker kit prices and question / do some have experience with these:
Question 1: why is this kit so cheap?
http://www.advancedautomotives.com/s...vcs-1407-p.asp
it has manley rods, mahle pistons, looks like any other kit out there, with the fact i see it only comes in 2 piston sizes, while rcm comes in 3. but that's not biggie as I need to buy the block too.
Question 2:
What kind of power can we safely run on this Budget RCM kit?
http://rogerclarkmotorsport.co.uk/st...roker-kit-ej20
Obviously cutting my stroker parts prices will save me money on the build, money I can use on my new turbo, cuz everything else needed mods wise is already in the car.
thanks.

It all depends on what block you use, what size rods, oil pump, pan, which pistons use and better pistons will give more power capability and labour etc.
If going for a decent 600 power capable build will cost around 5k ish to build fully complete.
So just to buy the kit there's more to it etc.
If using a cdb then the matching of rear thrust is to consider also.

Of course , I won't buy the kits or anything, but as I said, i`m curious why is that kit like half price of a decent RCM kit let's say cuz that's £2300, and again did anyone try their budget kit at £1600 cuz that's agian cheaper but has the "name to it".
It's a whole lot more to it than it meets the eye, just trying to debug this as price differences are huge in this area.
everything else I saw roughly it's same cost (oil pump, timing belt kits, heads, etc)

Ive recently had a 2.1 stroker built & fitted by enginetuner and i paid more than 4.5k , but all depends on the parts used i suppose . I also sourced my own CDB for the build aswell so i could push 500bhp if wanted

+1 for TDR had my 2.1 stroker built by them with an ej207 SCDB, price started off around 4.5k but over a couple of years and project creep it increased just a little

Sounds nice mate,what power did it make? Any graphs?...tbh I've already got the sc46,syvecs,injectors,gt spec headers,exhaust...but I'm looking at going rotated with a Gt35r...my plan is getting a 2.1 stroker end of January at tdr then running it in..once ran in hopefully buying a rotated kit from rcm and the Gt35r for mark to map...sounds straight forward to me
1st mapping session after 1000 mile run in. Managed a healthy 384hp and 330ft/lb.
2nd mapping session at 3000 miles achieved 442bhp and 390ft/lb.
Flywheel bhp and torque
Boost, AFR and at the wheel bhp
Ahhh sorry so literally just a 2.1 stroker build then if you have all the other supporting mods . ..With a rotated GT35r I'd have thought you should get around 550 - 600bhp on a 2.1!?
I think Dubzy is running a 2.35 stroker with a Scoobyclinic/Blouch GT35R equivalent with very good results . . .have a good chat with Mark he's a very helpful, understanding and knowledgeable chap.
Good luck with the build
... things may sound straightforward but there is always something that bites you in the *** ... only reason I've have a Syvecs ECU is because Simtek/Alcatek ECU would barely start the engine. I think a total of 5 different ones were tried in my car but none could start or keep the engine idling below 3k rpm. . .however they would all work in other Subarus!! OEM ecu would start and idle the engine but obviously wasn't aware of the mods . .
So in the end bit the bullet and went for a Syvecs and started first time

How is that going ?
I am unsure whether to go for a stroker or the syvecs first

Yeah syvecs and sc46 billet on stock bottom end...I'm certainly no expert but car drives perfectly fine although I no engine is probably at its limit.
#17
Scooby Regular
Did u make any gains just by adding syvecs or did u do turbo and ecu at same time,
I'm trying to find out what gains if any by switching ecu alone.

Ahh right...I had all my bolt on parts already but in may gone my car was around 410bhp so I swapped the 2.75inch miltek with a sports cat for a new straight through 3 inch mongoose and bought a new 3 bar map sensor and power went up to 445 from 410,then with meth map went upto 475.

410bhp @ 2.75 with sport cat SC46 ? Syvecs too ?? Can u remember boost level ?
445 bhp - 3" decat and 3bar to get more boost with sc46 and syvecs ? what boost if u know ?
Cheers

Duncan at race dynamics did 410bhp bhp map at 1.6bar with syvecs...pat at scoobyclinic did 445 bhp map with syvecs at 1.8bar in may gone with exhaust and may sensor

My sc42 been tinkered with by Owen Developments makes 397 @ 1.6 bar on OEM ecu,
Like the idea of upping the boost and going syvecs, just unsure if i should be forging first,
So almost a year at 1.8 bar and 445bhp, are you forging for piece of mind or have u had any issues at that power ?

Im currently using it on v power and methanol and it's an animal at 475...there's absolutely no issues although I drive like miss daisy most the time,plus with this sh1te weather its hardly getting used...I've got the bug for more power plus I'd rather not use methanol...I'm hoping for close to 600...getting it built for shows next summer
My thoughts are if your pushing the limits then have money put aside just incase..my car has done around 4000 miles in the 18 months I've had it but the oil is changed every couple months regardless of mileage

Nice numbers...How was the service from owen developments? My sc46 billet will be getting sent away for a refresh then sold on here when I buy my Gt35r...just not sure where to send it

It started as SC42 then remachined to fit bigger billet wheel, upgraded bearings and heatshield , pretty much their HTA M-spec now.
Owens have been more than happy to search their files and send me all the details of the work they carried out, as well as any other requests.
Wouldn't think twice about using them
I would actually ask what they can do as far as upgrades on your SC46 they might surprise you.

Not sure about the initial service or cost as i bough it already complete on here,

Machining on the block was a work of art, all top end proven components used, far better than what comes in these generic "stroker kits".
With most of these things the proof is in the pudding and my pudding has been extremely reliable and goes very very well. It's fair to say that engine has done me well this season.
As always Alyn was spot on, I wouldn't and won't use anyone else! Joe

This isnt the 1st time i've read of the SC42 having issues tho which concerns me, theyre not exactly cheap. Why would one need tinkering with to perform as it should?
I understand that the supporting components ultimately determine its productivity but have now read about cracked housings and oil issues so should I be worried?
