Any info

 

Rocking horse s**t. Better of buying a V1/2 car.

 

tons on eBay for sale

 

Can't trust eBay full of con artists plus eBay are a nightmare when problems start hence why I asked on here

 

The semi closed deck on Newage Stis is man enough even for big power engines and readily available.

 

Try my man Tim at Heathrow performance, he can help with any questions and should be able to source you 1

Ok thanks will give him a call

 

I bought a load at 1 point. Had 16 in total.
Sold to a load of big companies like RCM, lateral and RA motorsport.
This was 7 or years ago when they were £100-£200.
Never managed anything so lucrative since.
Tbh you don't need a CDB unless going 500bhp plus

 

My plan is a 550 bhp build so closed deck block is were I'm at just now I was originally going to buy a car first but decided to get the parts sorted and look for a type r to fit my build into. A 2.1 engine with 6 speed sti conversion going for 550 bhp that's my plan should make for a quick car on the track

 

We're happy to use an open deck block at around 400 bhp. A semi closed is good for 500 and a closed deck above that, given the option.
Having said that, this is a wish list. We've seen an open deck block run for years at 520 bhp before it started leaking a bit..
In all honesty, you can't beat a closed deck block, so why Subaru decided to deprive us of them I don't know, unless it was to save a bit of cash.
Let's face it, they don't want the likes of us messing about with them, do they?

 

What are your thoughts on block pinning or sleeving? Is the cost to much?
And at what power can you run these two options ?

 

Yep, cash. CDB much more expensive to manufacture.

 

And no real benefit on a standard factory car, so makes sense to use the cheaper option.

 

I've never liked the look of pinning, sleeving just introduces another host of failure points. We often have the top deck plates done on 2.5 blocks, no regrets there so far.

 

True enough, again, why should they worry about what we do?

 

What about when they close the deck off using an insert ?
What's that called ?
And how would you rate that method ?

 

closed deck converting is not mega pricey, iirc around £500

mines speced for 550, photo of a normal and closed deck converted,

 

This is what I was looking at,

Guess it wouldn't matter if you start with semi closed or fully open if you go this route ?

 

how did the conversion process go? do they just fill it with ally? sorry if that sounds stupid!

 

You Need to speak Alyn up at AS Performance about the closed deck inserts, he's been doing them for years and are tried and tested, a lot of the 2.5 boys use them.
He also does it for the normal 2.0L blocks.
A good option in my eyes, especially if you know your ODB is a good one, I'd rather have an insert put into my good ODB rather than take on an unknown quantity CDB.
Speak to Alyn

 

nah its fine, many ways you could theoretically do it.

Im not 100% sure on the exact process different companies use butmy understanding is the block is machined to suit then the insert is pressed in, then the face machined flat.

 

So would it matter if you have fully open or semi closed ?

If u put insert in both and machine u will be left with same thing am i correct ?

Or are there other differences ?

 

yes you would end up with the same end results with either hence get a odb as they are cheaper

 

My thoughts exactly
