Hey guys,
I have a 70mm skunk2 alpha throttle body.
But these things are known for huge boost leaks.
Is there a 70mm throttle body with zero boost leak for boosted applications?
thank you

Aren't skunk2 sticky too ?

The ballade sports throttle body looks exactly like the skunk2 alpha.
don't know if it would be better
SOS bores oem Honda throttle bodys. but they are a lot smaller. Only 64,2 mm max. for the AP1.

Just keep it oem or sos, MY skunk2 leaks the Wilson & Hypertune seem's to make the best throttle body's but they are not cheap and it will be a custom install they use the ford 90mm style mounting.

I've got a 74mm Skunk2 but have not installed it yet. I read a few ppl having issues with it but also a lot of ppl who swear by it.

The 74mm Pro series throttle bodies from Skunk2 are solid, I had one on my car for a year no issues. I am parting out my setup and have one for sale if anyone needs it.

SOS if you want an improvement in performance with the ability to reliably run water/meth injection and have OEM reliability/longevity. Ive put a lot of miles on mine over the years and a large portion of that time was injecting fluids through it with never a hiccup. No matter what size you go with, if you want the full benefits of any larger TB you must port match the inlet of the manifold. OEM to SOS goes from 62.5 to 64mm with a 70 mm face. You can go up to 70mm intake opening before running into the water jacket.

I do not want to run water / meth injection.
I have the full blown intake manifold, so no need for port matching.
The 64mm SOS throttle body is a really small gain over the stock 62,5mm.
So I am still looking for a good 70mm option which fits on the fb intake mani.
Perhaps I am buying a 70mm Skunk2 pro tb and do a custom shaft sealing.

I was thinking of doing the same thing I really like the skunk2 throttle body just sucks they don't put a shaft seal on it. You can buy evo shafts seals just not sure on the size of the skunk2 shaft. Dont get me wrong I'm not saying they are bad just cant understand why they don't seal them. I even when as far as contacting technical support because I thought it was defective, and they said "we don't make a throttle body that seals 100% on boosted application). If you end up trying to seal it let me know how it worked out.
