A guy in my country is selling a brand new Edelbrock High-Flo Throttle Body 4789 for about a third of the original cost.

He claims this will fit on all the B-series engines, and since I am doing some upgrades on my Del Sol with a B16A2 this summer I thought this might be a bargain. It appears that this product is discontinued and the information from a few online retailers with the item still in stock says this is designed for a 96-01 Acura Integra Type R with B18 engine and that's why I wanna make sure that if I do purchase this, it will actually fit my engine. I'm running a stock intake manifold and a short ram intake. I know without at least porting and polishing my intake manifold I probably won't see much gains in terms of horsepower, but should this throttle body work, could I expect some power gains across the rev range?
Thank you.

Edit: I realise that I posted this in the "Forced induction" section when I meant to put it in the "Naturally Aspirated" section. Mods feel free to move it to the correct place.

 

Yes, it will work. Can mix/match any B series throttle body with any B series intake. The most that may change in some cases is the throttle cable bracket (but only if you're using like a S2 Ultra style intake, or something similar).

Just port match/bore out the intake to match the opening of the TB so you don't have that nasty lip/overhang from the intake manifold.

 

+1 on matching the TB to manifold and using the correct sized gasket

 

Throttlebody and intake manifold aren’t bottlenecks in B16A, even in slightly modified one (like cams, header, exhaust). Of course you will see minor gains top up (when fuel tables corrected) but same time losing some precice throttle feel in lower load areas. But depending your future plans with this engine, 65mm is good choise, not so ”over sized” but still gives room to grow.
That short intake pipe is ok when using filterbox and fresh air piping or some other way that keeps intake air temperature near to ambient temp, because of air density.

OT: are you from Norge?

 

Late reply, but yes, I am from Norway
