Only reason why quad throttle bodys are not the choice for forced induction is that its adding extra stuff to complicate things.

For a NA setup, quads all the way i reckon, for no other reason than bragging rights.

Still, it has been bugging me to buy this. Would be good for experimenting.

Matto1kute, PM me if the payment falls though.

theese are sold pending payment

Hmm, OK. Bit narrower than std DHLA/DCOE centres.

Will have to do a bit of measuring..

I have very similar CBR600RR throttle bodies I'm planning to put on my A15. There are two pairs joined in the middle. I plan to seperate them and alighn the centre of each pair with the centre of each pair of ports on the head for symetrical runners. At 80mm centres you'd need to add about 18mm to the space between the pairs, mine are 74mm centres. A work in progress, slow progress.

about 80mm on all. appears to have even spacing even between them

just the centre to centre between the bores i.e. centre of one throttle plate to the next..

yea they are 2 pieces. not sure whta u mean by spacing. from where to where?

Regarding the injector sizing question above, dunno the cc rating but they are capable of supporting 160+hp @ 10000rpm plus

Hey Matto,

What is the centre spacing between the throttle bodies?

And are they the type that bolt together in the middle i.e. two pairs? Look like it from the pic but can't tell for sure..

Nice work Matto, GL with sale.

You guys should just try an offer, you may be surprised. Matto's pretty good with his prices.
