veritech-z Posted August 29, 2006 Share Posted August 29, 2006 Wasn't Olie05 talking about doing something like that too at one point? Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted August 29, 2006 Author Share Posted August 29, 2006 yep. Olie had a thread going with doing this to a perfectly good set of webers. I think I have a use for my old roundtops now...blowthrough SUs on a turbo. Since it "doesn't work very well" to do a blowthrough SU turbo setup...

olie05 Posted August 29, 2006 Share Posted August 29, 2006 yep. Olie had a thread going with doing this to a perfectly good set of webers. You make that sound like a bad thing! What good are carbs for these days anyway? lol EFI ftw Quote Link to comment Share on other sites More sharing options...
veritech-z Posted August 29, 2006 Share Posted August 29, 2006 Hey Olie, did you get anywhere with that yet? Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted August 29, 2006 Author Share Posted August 29, 2006 yeah...maybe he just doesn't want to tell us that he decided to run regular Webers... so what would it take to convert a pair of SUs into a TBI setup? Obviously the big top would be where the injector sits but what about the other parts? what is needed fora TBI setup? I think the butterfly valve should work with some mods. I'll go get some pics Quote Link to comment Share on other sites More sharing options...
olie05 Posted August 29, 2006 Share Posted August 29, 2006 Hey Olie, did you get anywhere with that yet? no, i don't have the money to junk a good set of webers or mikunis (yet) back to the original topic, the way i was planning on doing this was by grinding out alot of the internal castings, and unecessary carb parts, making room for an injector. Clearly this is much easier to do on an SU than a weber due to the nice little dome to stick an injector into. Also, this would be the perfect opportunity to do your tripple SU setup, without having to worry about "over carbing" the engine. Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted August 29, 2006 Author Share Posted August 29, 2006 sigh...that would be a lot of work...tripple SUs and EFI.. Quote Link to comment Share on other sites More sharing options...
Alex_V Posted August 30, 2006 Share Posted August 30, 2006 Have you guys looked at VG30E TB's? They have 2 semi joined ~45mm openings and would be common as they came on 84-94 maximas (only 92-94 GXE's) and some Z31's had them. Ill have to get a pic for you guys that dont know what they look like.

OlderThanMe Posted August 30, 2006 Author Share Posted August 30, 2006 interesting. I don't know if the converting the stock runners to efi will be worth it though. Quote Link to comment Share on other sites More sharing options...
veritech-z Posted August 30, 2006 Share Posted August 30, 2006 That still leaves you either using a tripple carb manifold drilled for six injectors, or doing it like twm and some other companies do where the fuel rail sprays fuel down the throat of the throttle body.

Xander Posted August 31, 2006 Share Posted August 31, 2006 ok, here a new idea. I have worked on pontiac fiero's a lot in the past (don't ask). A throttle body of a v6 fiero will directly bolt up to a carb manifold! the TB's are cheap. I was thinking of using the base of a injection manifold with the injectors and welding the runners of the carb manifold to it. then just use 2 fiero throttle body's. The TB's come with TPS and idle aire controll. I believe that the TB's are something like 55 mm each. that should be plenty. Quote Link to comment Share on other sites More sharing options...
zane9000 Posted August 31, 2006 Share Posted August 31, 2006 xander, know anyone that is selling those throttle bodies? or am i going to be making a trip to the junk yard? Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted August 31, 2006 Author Share Posted August 31, 2006 Hey xander, are the fiero TB's TBI or TPI? Quote Link to comment Share on other sites More sharing options...
veritech-z Posted August 31, 2006 Share Posted August 31, 2006 He's describing them as TPI, he said you would weld the fuel injection injector bosses to your carb manifold. Quote Link to comment Share on other sites More sharing options...
olie05 Posted August 31, 2006 Share Posted August 31, 2006 i wouldn't call them TPI... that implies tuned port injection, a chevy thing. More like direct port Fuel injection. Quote Link to comment Share on other sites More sharing options...
veritech-z Posted August 31, 2006 Share Posted August 31, 2006 Multi-port sequential, whatever you want to call it. I don't know what GM called it when they used it on the fiero, if it was the same as when they used it on chevy's or not. Point being it's not TBI.

Xander Posted September 1, 2006 Share Posted September 1, 2006 I don't know what GM called it when they used it on the fiero probably they called it junk. just like the rest of the people that ever worked on a fiero. come on.. 2.8 liter v6 with 135 HP that is just stupid. The v6 fiero has 6 injectors so it is port injection. the 4 cylinder fiero was tbi. fiero's do have some usefull parts though. the seats are very good. and it has all the sensors you will need for a megasquirt setup . the TB's show up on ebayu some times. but you are probably better off going to the junkyard.
