Ideas for rebuild


DXROLLA

Recommended Posts

Im starting to think about different ideas for a rebuild on my v2 sti ra. It has now done just over 190,000km so everything is starting to get a bit tired.

One option ive been looking at is buying a PBMS forged block like the one below

Or the other option is just a standard rebuild with STI bits which i havn't yet priced up.

Id like your thoughts on how far i should go, power wise i would like around 300-350hp nothing huge. I'm more after getting some reliability so i can do some track days and drag days, maybe the odd sealed hill climb as well.

I will be getting a baffled sump to start with, is there anything else that needs to be done to prevent bearing failure?

Any other ideas would be great, i will be doing most of the work myself apart from the machining which i have a couple of mates that can do that which will cut cost.

As for the bolt on bits im hoping the tdo5 will be up to the task? Would like to stay away from a front mount and just upgrade the top mount if possible, unless you think i may run into issue, but i have herd of some cars making good power with a top mount so hopefully it should be ok.

As far as injectors is it worth while upgrading to the yellow injectors? Also look at upgrading the fuel pump as well maybe a walbro?

Any other ideas would be great.

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
