you would be best giving alan a phone steve, there are so many different options you could make with it ,alan will keep you right.....

scott

 

You aren't far off there!

 

what kinda price we talking for custom pistons and or rods if i were to choose say an 81mm or 83mm crank Alan? block would have to be modded for big stroke on the 83mm i understand

pm me up if you like?

 

The perfect retort Alan & one I shall hve to use from now on!

 

Hi Alan,
Was at castle combe today had a lovely day but after a day of track sessions my big end bearings are on the way out.
I have a 1998 version 4 WRX STI Type R.

Is there anything you can do for me? Am thinking stroker,turbo and Simtek ecu?
Could I give you a call to discuss options?

Could give you the whole car or just the engine.
Only problem is timeline, I have a ring trip booked for the end of may and would like my car ready for then.

Kind regards
Jimmy

 

is it possible to use the 2.1 stroker in a ej207 avcs (2002), if the block has already been rebored to 92,5 and has small scores ca it be reused( rebored)? what would be the price if block can't be reused
thank you

 

Hi whats the run in procedure/mileage for a freshly made 2.1?

 

Hi Jimmy

We'd love to hear from you, you can call me on 01752 345880 office hours, or pm me a number and I'll call you over the weekend. We work 24/7!
I'm always prepared to put myself and my staff out to help somebody who wants to do something with their car, I still can't get motorsport out of my system!

 

We wouldn't be at all worried about going to 1mm overbore on any Impreza block, the pistons are usually available from stock.

 

This is my routine. 50 miles on mineral oil. Then change the oil and filter, using mineral oil. Change it again at 500 miles, again mineral. Then go semi synthetic at 1000 miles.
We prefer to see 1000 miles before sustained high load mapping takes place.
Fully synthetic oil at 2000 miles minimum.
Of course the mileage is only a guide. You can run an engine in faster by leaving it in a lower gear and use a little more revs, say 3800 in 4th rather than 3000 in 5th? It's about the number of times the piston moves up and down the bore!
I know plenty of people who don't run them in hardly at all, and they don't actually go bang, I'd just prefer to take it steady after spending all that time and money! Think of it as a new GF you've been after for ages, like don't rush in on the first date!
When running in, I prefer to keep the motor moving, slight push through the gears, but short shift. don't treat it too gently, it's only full load under high boost that's going to compromise it. Mixed driving is best.

 

thanks for the answer,
so with 1 mm overbore there is still enough friction material left on the liners ( i just bought the car and had the engine taken apart because it had some piston slap and i've noticed it has been overbored with 92.5mm wiseco pistons , but i guess it wasnt properly gaped as and i noticed fine scores on the walls)
what would be the cost for 2,1 kit if is send you the block, or is it on exchange basis?

 

Short block using your block is £2050 including vat. This includes a new 2.5 crank, Wiseco pistons, K1 rods, and Cosworth or ACL race bearings, depending on what's available! One week of no commercial flying can cause havoc.. The block will be fully stripped and cleaned, we use stress plates for boring and honing, and the assembly is balanced. We paint the block silver, and it arrives back to you ready to install.

 

Hi Alan,
Thats great, i have only just logged on and got your message, I will ring you in the morning if thats okay?

It will be good to discuss the options with you so you can point me in the right direction.

I will give you a call around 10ish if thats convient? Gives you a chance to get through the door.

Thank you
Jimmy

 

A 1000 miles is hardly the 1st date Alan. Thats more like going 3 months without any

 

Better a patient and gentle approach to prevent going off half cocked!

 

alan or martyn what would you say your stroker setup would take power wise it would be used on the drag strip and sprints so would be put through some high revs but i want to keep it as safe as posible

 

Scott ended up with 630 on V power, running 2 bar boost with a GT35/42.
Martyn runs his at up to 558 on race fuel using the S206 turbo.
What rpm are you planning on running up to?

 

its more about when i down shift as i have hit 8k on more than 1 ocasion which i know isnt good for any engine

 

The short block will handle that ok, although I'm not certain about your valve train! Some types have a habit of spitting shims out. Martyn runs to 8300 in fourth on the strip using standard STi V5 heads. That last statement isn't a recommendation!

 

thats all i needed to know thanks will be in touch soon when i pick the new block up as for the valves im hopeing the +1mm supertecks should withstand it

 

martyn has my rev limiter set at 8250 and no issues there

 

The valves should be fine, it's about controlling float as much as anything else.
The correct springs make a difference if you are pushing rpm. The trick is to use a spring that keeps the lifter following the profile of the cam. If the spring is too weak, the inertia will cause the valve to stay open at high rpm when it should be shutting. This causes the problem of certain types of shim going walkabout in the cam chest. If the spring is too strong you are just wasting power, and risk damaging the cam lobe.
Cosworth springs £210 delivered, or there are alternatives from Piper, Kent cams, etc.

 

do you know what stage of running in my murtaya is at and what spec fully synthetic oil do you recommend?
martin

 

Hi Martin

We would keep yours on mineral for at least 1000 miles yet, it's hardly done any running really.

 

ok thanks
martin
ps i take it you mean 100 miles??

 

No, he means 1000 miles

 

ahh lol
martin

 

stealing alan's thread, with his permission(thanks alan)...

just to let anyone know who might be interested in 1 of these fine engines, my car which has 1 fitted along with a load of other mods, making 627bhp(thanks to martyn) is now up for sale.....£15,500 or nearest offer.....gutted that i am having to sell but change to family circumstances means it has to go

full spec to follow on for sale section and on pistonheads when i get time tomorrow(or feel free to speak to alan or martyn about the car - they will vouch for it)., any inspection will be welcome, any1 interested can phone me on 07817 213702 or email/pm me.... email scottmarundel@blackberry.orange.co.uk
