Welp, already daydreaming about the 2.5 swap. Need to plan out and budget to see how much I can spend but hopefully I'll get a little bit of money for my nc2 motor to offset the cost.
Build option 1
Typical 2.5 swap with esslinger stage 2 cams. Maybe a basic spring upgrade for safety.
Estimate 190-200rwhp and tq slightly below that.
Likely about 1200-1500 total cost, maybe less once I sell my motor.
Build option 2
See if I can source oem ecotec pistons with esslinger stage 4 cams for a slightly higher compression build. Costs would go up significantly due to needing to do bearings, springs, maybe rods etc and even more if this is something I'd end up having to pay a shop to assemble.
Likely 2000-2500 for everything maybe a bit more with assembly. Less whatever I get for my motor.
Estimate would be like 220-230rwhp. Unsure of tq but likely around option 1 if not a bit less.
Anyone have thoughts? Vtechkiller is firmly in the build 1 camp ala KISS mentality to get something enjoyable that's more reliable and has less chance for headache. Option 1 also leaves the door open for boost down the line.
Thinking of doing the swap sometime next spring. I just applied for fellowship and may gift it to myself if I match well!

Build option 1. You said at some stage you'd like for your mother to have the ability to drive it IIRC? I don't know your mum, she may be Janet Guthrie in disguise, but if she is like mine, I don;t think she would like stage 4 cams

Hah. EFRs are expensive. Hopefully there will be used kits out there when I'm ready. That or Lars or kraken will be making NC kits!

Someone suggested doing the higher compression motor but using the esslinger stage 3 cams to keep it a bit more daily friendly and I'm intrigued.
I need to call the guy that built my NB motor and see if he's still doing his thing.

Against Cameron's better judgement, because mine is clearly suspect, I've decided to start collecting parts for the high comp piston build.
Will shoot for 220-230 on pump 93. Currently mixed on whether or not I end up doing the rods, but in terms of the 'might as wells' it seems to make sense. Given the nature of the 2.5's, you can't really rev the stock setup to much past 7k without a bunch of risk. I think Cameron sets the rev limiter of the cars he tunes to about 7k, but most cars make peak power at 6500-6800 so it works out. With rods, it's feasible to spin up to 7500 with a little bit of a margin, which sounds like it would certainly make things more interesting.
Goal for the cost aspect of things was not to really spend more than a (2 wk) paycheck on this. I'm due to apply for another credit card to build credit and found something that would give me a grand in cash back if I hit an attainable minimum over 3 months. Will likely throw that 'free money' (aka taxed bonus) into the pot to get the build all set up. Already been stalking a yard out near me and they have some good motors but I need to do a few things before I can go buy one since I have nowhere to put thanks to the apartment living.
Goal at this point is to have parts collected and motor bought by mid october, so I can drop things off at the machine shop when I'm on vacation. I'd love to assemble the motor myself since it would take a ton off the budget, but I'm not sure it's worth learning on a project like this where a mistake would totally screw up the timeline and inconvenience not only me but also a friend who's being kind enough to let me use his garage/lift for the swap.
