Hi can sp2 throttle body will fit into SP1 turnone airbox ?

The SP2 throttle bodies will fit with a T-O SP1 airbox.
You'll also need the mount rubbers for the throttle bodies to mount.
Plus the SP2 ECU.

However, the T-O SP1 airbox itself will not fit in an SP2 frame due to the added gussets near the steering head.
The T-O SP2 airbox will fit both models.

I have tried it from stock till up by +2..
So far more fast pick up is +44, my setting..

Because im a bit abit confused on up grade to Sp2 throttle body..
someone told me it not necessary to use SP ECU if i have PC3..
IS it possible..

I adapted SP2 injectors to fit into my SP1 without the SP2 ECU but using a power commander.It need a remap, but in the end there was no real power difference, it did seam to have smoother throttle responce, but I ended up switching back to SP1 injectors, just to keep it a SP1:)
