I've recently bought a S2000 tb for the H22.

I cant find much online and the info I did find, mention some <U>difficulties with the evap signal....</U>

Question 1: How hard is installation and can someone shed some light on the evap problem and how to fix? (98VTEC hint-hint)

Also, I concluded that the main consensus is that an over sized TB would not necessarily produce gains, and that they sometimes cause power loss on a relatively stock engine....

I have pretty significant mods:
Darton sleeves
Mahle 11.5:1 pistons
Eagle rods
Full Crower valve train & stage 2 cams
DSM 450 injectors
RS-R header
Apexi exhaust
test pipe
Iceman CAI
P28 (haven't connected it yet, engine is out of the car for auto to manual tensioner swap, but I will be able to tune with crome to iron out any AF spikes... )

Question 2: Any predictions on gains?

Thanks in advance!

 

1. it works perfect
2. no

 

1: so no evap problem? just portmatching it and it retains oem functionality??
if so, then cool!!

2: reason for asking any predictions on gains: I opted for the larger tb against hayabusa ITB's because of the fabrications and prolly alot of hassle involved.......dunno if I made the right choice though......

 

the busa throttles really arent that hard to do if you can spend the money for proper runner fabrication. The biggest problem i had was figuring out how to keep the throttle return springs from popping out of place.

well, lol, i dont have any of that stuff. No evap, no EGR, etc. I was saying it worked perfectly as all i did was bolt it on and everything worked.
