Hello as the title says I can't decide between the .81 A/R hot side or the .68A/R for my setup... I'm currently Running a Turbonetics 1.15 A/R divided hot side on an open manifold so im loosing out on that precious spool time as it is... I'm trying to pick up at least 1000k of spool witch one should I use without choking my top end power here is my dyno sheet as of now..

 

A lot would depend on the setup, what kind of power are you shooting for ?

 

Keep it small, as long as the exhaust wheel doesn't change, and it might help you with the amount or powerband you're looking for. But you're asking a lot for such low boost pressure on an enormously large turbocharger for only 2.2 litres.

 

Yeah I’m keeping everything the same and I’m just swapping the hot side out... I’m just trying to get more mid-range and have the power band be more of a transition instead of just straight up. Yes your right, that why I was planning on raising the boost I’m just trying to get everything in order before I retune I want a smaller hot side for quicker spool and I was going to ditch these delta cams for the stock JDM H22 cams and I ordered a set of 1600cc and a 340lph fuel pump and I’m going to retune on E85 sometime in the spring, so then i can run more boost and timing and see what I can hit. I’m just going for 550-600whp. it is a large turbo for a street car... It is stroked to a 2.4L so that helps a bit but I do have major boost lag haha I just like the larger turbo I dont have to be in boost all the time so I save a **** ton on gas.

 

Do you have a printout with boost? When do you have your vtec starting?

You would be better off with a 6262 for that power level and your goals of spooling sooner IMO.

 

No I don't.. my vtec is set to 4.5k yeah I agree with the 6262 being beter suited I pucked this turbo up for 850 bux brand new from a friend so i couldnt pass it up!
