Air in- air out. . You should get a nice turbo. the modded HX35 from piers is nice(40, better). Make up a nice intake and a big AFE filter(don't use K&N as they let dust through). You already have the exhaust covered. Get a 366 spring it's a HOOT!
PODS? some people like em but I don't, too much unburned fuel due to sloppy spray pattern and the way the tip is desinged overall. . They do have a LOT of power though. . You can also get a bit more travel on your throttle shaft (which just pulls on the gov spring more}. also make sure your pedal travels good ... ... I like the IP timed at 1. 41mm
Still crisp in the low end there. too much advance and you loose low end. use a gauge to get TDC and to set the pump.
just pushing it up 1/8" from stock could get you anywere fron 1. 3 to 1. 7 or beyond. . It's also good to know were true TDC is. the pin isn't that accurate.
Spring , pump mods/tweaks and timing are cheap, add a few bucks and get a fuel pin, another great upgrade!... ... ... .
I'll add that porting your exhaust housing and manifold can really help in some situations as well. 16cm size housing is a good one to work with. .
