 FOUND...cheap 48mm weber velocity stacks for the silvertop. Reply  Edit


some people tend to use the 44mm velocity stacks from weber carbs, but as we know, theres a difference from the 48mm Silvertop ITB diameter. usually the sets go for about $60 for 4 shipped. I found a set of 48mm weber velocity stacks on the web after a lot of searching. i just ordered a set for myself, and each stack is under $7. thats under $28 for a set +shipping, which came out to just over $40. They are on their way right now so well see about fitment, im sure ill have to mod the mounting points, but figured i would share this great alternative to the $180 set at T3(they are super nice, but expensive.)

Good, very good! Plus they're shorter than my T3. And I bet Weber is quality.

I'm running the 6 inch "race stacks" from that same site I believe. I of course ran into mounting issues...and then I got creative. made some aluminum plates, great fit, and not terribly ugly.
I think Hbomb is running these same 6 inch stacks. I have yet to hear how they sound, but I imagine the process to mount the ones you bought would be the same. overall, still more affordable than other options... and you get that DIY feeling of accomplishment! lol

6" huh? couldnt find any longer ones withthe same 48mm I.D., only 44mm I.D. and longer.

the holes need to be changed, so ill machine some washers too for it. got them in the other day, just haven't had time to work on it.

Hey Morgan, here's the mounting plates I made to mount my 6 inch stacks. I believe they're the same size at the base as yours. I had planned to bevel the edge of the larger hole, thats where theres a score mark larger than the itb. turns out I didn't need to. looking down the stack, there's no lip to the throttles, just smooth. turned out really well. all holes are tapped in the plates, there's no gap on either side. and still, a far more affordable option than other stacks...if you don't mind a little DIY look. I've since got some different bolts for the plates, I was just using the OEM stack bolts to mock it up

I wish I could say I put tons of thought into it lol went to a surplus metal outlet locally called Midwest Steel , picked up a section of 3/8 inch thick 5 inch wide, 30 inch long 6061 aluminum (it cost about $17, and I got extra on purpose cause I figured I'd mess up a little), placed a velocity stack on the bar, eyeballed it, drew a line to measure out my first rough plate, and basically duplicated it 3 more times.
started out looking like this...

it was a lot of ballparking, guess work, and winging it really. just worked off an idea in my head and it panned out well. As far as mounting the stack, you gotta get the correct length bolt if you mount them askew on the plate or they hit the itb's behind it. I believe I finally settled on M7 16mm bolts for mounting the stack to the plate. If I recall right, mounting the plate to the ITB uses the oem stack mounting bolt size of M8 1.25, but don't quote me on that.

It's been a while but if I remember correctly, the I.D. of the short ones I bought are just a bit smaller than my ST ITBs. Was planning on making a fixture and putting them on a lathe to open them up just a bit

46mm is too small, normally you have the largest diameter at the tip of the bell and the narrowest point at the choke in the port, with it tappered inbetween.

Those stacks are absurdly cheap but not of design very good for perfomance. However if the extra money is worth the extra performance then that's up to the person.

Hi everyone! New to this forum! I mainly registered here because I had this question for a while: I have an 1986 MR2 with a stock silvertop swap. Morgan posted these up a while ago on this thread and SCT also bought some of them I think!
http://www.cbperformance.com/c...D=512

But I mostly wondered if these fitted:
http://www.cip1.ca/ProductDeta...2D199

Do these fit inside the stock silvertop plenum (take off stock brown trumpets and just bolt these in)? I read the thread but I'm not sure if you guys are talking about velocity stacks INSIDE the stock plenum or not. :S And if it does, is there any noticable gains with them? I read up on a another forum that a guy played with the stock trumpets a while ago and gained as much as 11hp out of them or something just by messing with them! I also think he said the smaller they are the better it actually is (inside the plenum of course). Thank you very much!

Alright thanks I'll wait for your measurements morgan! I really want to retain the afm and original silvertop ECU so any open air stacks = out of the question!

FYI, the picture I posted above are the 2 1/8" stack and they fit inside the stock silvertop box. Not a lot of room, though. Switching to a blacktop box made everything better.

Alright that's what I thought when I saw that picture but wasn't too sure! I think they look great! But you mentioned that there isn't a lot of room; can I close everything back together with the silvertop box easily without tinkering with the top cover? I don't plan on spending money on a blacktop box so I want to stay with the stock silvertop one. But really was it worth the trouble and money to put those in? Any differences (major or not) to stock (gains)? And lastly do you still have a link to the same exact ones as yours? Thank you very much and sorry for all the questions!
