Thread: quad throttle sr20v, sr20ve intake manifold

you probably would see better gains with itbs tuned vs larger IM with larger throttle untuned. but like you said outsourcing the itbs for the plenum would be the problem

m3 csl throttles
will post pictures of angled intake

I have a set of M3 throttles sitting here and was going to use them on my FWD 20V But are a bigger problem on a FWD than on a RWD with where the brake booster sits. Have a look at Derms SR16VE throttles he made for his car also using the M3's throttles.

They are 48mm and are sure they would do the job. Let me know if you are intersted. I am in Brisbane and could post it to you.

im in sydney so postage shouldnt be much

wat throttle body's are these?





edit: neva mind just found out they are E46 CSL throttle bodies

now i need to work out wat im going to do with my injectors
im running 2 injectors per cylinder so its going to be all very tight fit'
i found it hard enuff finding room for injectors on each runner with a single throttle body inlet manifold now with all the linkages of a itb inlet manifold its going to be very hard to make room for every thing

This is a production run for adapters that lift theses itb at 30 deg so theirs no proplem with the brake booster

have u got pictures of the M3 throttle body's fitted with that adapter plate?

are u selling these adapter plates? i was planing on getting my own machined up but if i can buy them already made it would be alot more easy

Not at this point, I dont have a picture. Will receive them on wednesday then I'll post a picture

Yes I will sell this

Will you be making these for the 20V as well?

Do you have RHD or LHD cars? Just wondering what side your brake booster is on that it will clear.
