2.3L Options

Recommended Posts

Hey guys,

I know this topic has been done to death, however wanted to know if there are any other options i may have over looked. I've considered the following;

1. Rare, but if i could find a 2.2L CDB I would use my existing components from my 2.1L (2.5L 79mm stroke rear thrust crank and rods) and build a 2.35, or

2. Get hold of a EJ207 2L semi CDB and sleeve, or

3. Use a 2L CDB i have that has a damaged bore and sleeve, lastly

4. Destroke a EJ257 semi CDB, I'm assuming this involves using a 2L 75mm stroke crank?

I assume destroking a EJ257 would be far cheaper than building up a 2L block, would rev higher, what I don't know is how it would respond in comparison to a stroked engine.

Does destroking a 2.5 have any issues with bottom end, i.e. due to larger diameter pistons in relation to a 97/97.5mm piston?

Any thoughts, ideas or options greatly appreciated.

Cheers

If you've already got a 2.0L block, then I'd go with sleeves and larger bore version.

Personally, I've always preferred the idea of the de-stroked ej25 and using longer rods. But only if the intake and exhaust manifolds (including the plenum) + the heads are developed to suit a higher rev range.

Most of the time, a well spec'ed 2.5L build will be a better option.

      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
