TurboSPFI

o2 sensors are made to have a "swing", this is the rich/lean swing as you describe. By having voltage vary from 0.00 - 0.999, it bounces from rich (0.99 volts) to lean (0.00 volts) to aquire an average 0.45 volts, equivelant to 14.7:1 stoichiometric ratio.

i was thinking the compressor side, sorry i didnt specify

has anyone ever.. painted their turbo? thought about painting their turbo? I'm thinkin engine paint, anyone think it wont work pm here!

bump

is there anything else we need to know? dremel sounds too easy for porting and polishing

I've never ported or polished anything and was wondering if there were any certain processes to follow when doing this. been considering P/P my turbo and heads also, what kind of "grind bits" work best? do i need multiple? how bout carbide burrs? i know they can take alot off quickly, but that might be the issue? how bout P/P my VF2? bore out the wastegate? anything? thanks

still no specs for RHB5's *bump*

gotcha

if it was, it would say VF7 then instead of the VF2 stamped on the thing :-\ (wouldnt it??)

If i can remember right, the RHF's are different than the RHB. RHF = new school RHB = old school Eh, such things as: stock boost setting max avail. boost setting EGT tolerances basically anything that can distinguish specs between a VF2, VF7, VF11, VF39, etc etc etc

mine is the VF2, came off an XT im curious if the VF7 came from wagons? already know vf11 is the legacy turbo already know vf39 is the WRX STi turbo back to the point.. specs! specs!

does anyone have these? im certain ive seen posts indicating that people have them but the 4x4 shop i goto doesnt carry a part number for them. Part numbers for the RS 5000's and 9000's would be nice to have Thanks

can anyone find em? im having just the funnest time looking up specs *edit* mainly looking for VF2-7 *edit*

Tranny?

anyone know what the stock wastegate setting on a ihi vf2 rhb5 is?

well torxxx, why would i bump it up to 10 psi if im already content with what i have now?

Northguy - u know my digits..:cool:

I couldnt disagree more.. You dont need all of that. I run a 9.5:1 now (SPFI) @ 8 psi without any problems

those solenoids go bad all the time

alaska that is

basically, when you get into deep mud, anything that can drag WILL! the diff bracket tends to drag alot... guess ill be doing this mod myself and reportin back

nope, wouldnt be a bad idea though, thx for the idea

could be because im only running 2 psi .. i did run it to 10 psi and experienced some bogging (lack of fuel im guessing) until i turned it down to around 6 psi

havent hit a fuel cut yet

simple.. there would be less drag if the "blades" were 4 inches higher simply by flipping the bracket upsidedown
