ITB's manifolds etc

Well moving on from a thread in the for sale section

I thought i might start to gather some information here

So just if you want to recap that thread



Maybe i will start some old school stuff




























Lots of mikuni set ups pictured there
And now with Harley bike's out selling General Motors car's in the US there will for sure be lots of 44's about and 48's

Also honda have a interesting carby and here is the pdf file with all the information

good thread!

i'm going to look at using GTiR quads, might be a little bit too big, will try to get some pics.

looking at using motorbike slide throttles too, if i can get some the right size.

Whats the gtir size ? 45mm



Ikeya formula after market throttle assy 45mm or 48mm

[roadsailing]

I'll post up here when i measure the diameter.

not that they are any easier to get than 20 valve quads, but it isn't like they bolt up anyway (20 valve ones)

Some nissan gtir multi throttle set ups













And the top of the line tomei engine



No dyno chart for that one but its around 320hp most people say

the 20v ones look better than the nissan ones.. the nissan ones are a pair cast together.. where as the toyota ones are true individual throttle bodies..the silver top ones are 43mm at the smallest point, and the black tops use 45mm quads.. the nissan ones look really small in comparison, but i don't know how big they are at the butterfly.. i'd use a set of 20v ones.. there so much easier to find, and people make manifold for them ready to bolt on..

i'm using a TechnoToyTuning small port ITB manifold.. and it's beautiful.. and quite cheap in comparison to having one made..

Yeah nice work there by T3 very compact work also see the tps is back facing so it make's the linkages on the under size making the bay look neat








looks like gtir ones are 45mm here is the judd version using 48's



Here is a few other pictures of 4age's intakes etc

the acel linkage is on the bottom as it would normally foul on the fuel rail those last 4AGEs....ohhh my god.....what i would give to get one of those...
