'go for it' over the next 2 years or so (funds permitting along the way) and take my st205 to he 450 to 500 bhp area. Now at the moment the biggest question in my mind is to go 86.5 on the stock block, or, stay 86 but have it sleeved. Sleeving seems favourite at the moment. would it be worth going 86.5 sleeved or would that be counter productive as it would involve removing even more block. or 86 sleeved and stroked?scoops wrote:Morning! i've taken the executive decision to
. and i have more or less come to the decision that , having it done is nothing less of a 'Good' thing to do.. because, it is a better and stronger material than the block, its designed for high tollerences and Will overall help fail safe your block.. where as if you dont sleeve it, and just that chance happens that something goes wrong... and you crack the block.. thats a lot of hard work and money down the pan!!.(sard), pistons (je)will then look at the cooling, not sure what the stock chargecooler is up to, possibly go front mount or maybe uprate the chargecooler. While the engines in bits will probably get the head gas flowed. We'll see how it goes. time to start saving me thinks. It does depend on what boost your looking at running - on a 3076 to get 500 your gonna be running alot of boost which wont help - the main thing to bare in mind is how hard the car will be driven. If your looking at alot of track days then its probably a good idea to get done - if there is a weakness its going to show up after prolonged hard use. - if you have the cash i personally would do it.- 9.722 @ 148 MPH ----- 07947883103 ---- www.centurymotorsport.comCentury Motorsport wrote:I have been running 500hp now for some time and have had no issues.
If its done right you can put your mind at rest

What turbo are you running?- 99% sure they're 87mm. Is that too much ? 
so far it has survived, but it's only been 9 months or so LOL. Using 86mm pistons though./ thick walled block here running a GT35R (eventually)! No sleeving, and expected 450+ soon. Will be far stronger than a non sleeved block despite the fact that more block material has been removed. For what it costs these days its definatley worth doing. If I was to do another build I would sleeve. That not to say you cant do it without sleeving though!. sleeved it is.. now 86 or 86.5....scoops wrote:right then.
go on! you'll gain like 30cc 
but thats still almost the displacement of a ped! and that can push like 15 stone! hehe This will give you maximum possible strength from your combination.
