caseys Posted June 6, 2009 Share Posted June 6, 2009 Hi all, I am looking around currently at what to do with my engine regarding reliability and what I should be replacing next. I am now looking at replacing the valve stem seals or possibly replacing the entire head with either brand new stock or going for a Stage 1 / Stage 2 / Stage 3 head. I'd like people in the know to give me some information on what I should be going for, regarding my current specification and the end target I have for the car. Car has 109k miles on it. Currently running UK Spec car GT35DBRR .62ar with PHR hosing kit (less than 10k miles on) Stock injector setup Walbro pump Emanage Blue Autobox In the last 4 months I have replaced: OEM Radiator Crank Pulley Aux Pulley Tensioner Front Main Seal Rear Main Seal Cam oil seals Water pump Oil pump A few other gaskets I have a setup of transmission coolers I bought from Kranz from the group buy, this will be fitted in the interim until I go manual. On my buy list is : V160/161 gearbox conversion Solaris or similar EMS 660+cc injectors, fuel rail + supporting ancilliaries Eventually new internals - rods, pistons, crank. I have been asking around suppliers, wondering what is the best way to go. Should I just get my head taken off and opened up, stem seals replaced, valves etc checked out? Or should I buy a new head? If so what sort? OEM/Stage1/2/3. What have people gone for in this situation? I have been looking at what I can get but I am after a very reliable and quick to spool street car mainly, sometimes taking it on the track. I want to avoid as much lag as possible and raw top end power is not my aim. I'm not after 1/4 mile times or high terminals. Eventually I want to light weight it as much as possible (ironic for a UK spec I know). Should I even to just save costs, do the rope trick with VSS replacement? They are not causing me an issue at the moment, but I want to be able to run 1.2/1.4/1.6 bar of boost and not be having issues, I want the sort of reliability where I can drive form the UK to the 'ring, 20 laps around it and hopefulyl drive back without missing a beat. Reliability is the main thing I'm looking for, then any reduction in lag, then power. Would it be best to try and save money and have VSSs replaced and use the saving of money towards my other intentional buys? What else can be checked when removing the head as sort of 'belt & braces' checking (as they horrendously use the phrase in IT at work...). Thanks for reading, I'd appreciate any feedback from people having gone through this and also opinions (and maybe tenders) from traders Si Quote Link to comment Share on other sites More sharing options...
