big-phil Posted April 15, 2006 Share Posted April 15, 2006 Went to my top secret junk yard this morning and found this 240sx throttle body. Is mine a 60mm already? Mine says Weber on it, and my intake manifold is ported from the other owner. They are both the same size. 240sx mine my intake Quote Link to comment Share on other sites More sharing options...
Guest 280ZForce Posted April 15, 2006 Share Posted April 15, 2006 i noticed that too. i had a weber tb on my last setup. the difference is the weber has a larger mouth in the front. if u measure the front of the weber it has approx 70mm opening and the 240sx is still 60mm.

premo-s12 Posted April 15, 2006 Share Posted April 15, 2006 how much do those weber's typically go for? i assume the bolt pattern is the same as a stock TB on say...a Z-31 or 240? how about the TPS shaft? Quote Link to comment Share on other sites More sharing options...
big-phil Posted April 15, 2006 Author Share Posted April 15, 2006 Yes my weber is much bigger than the 240sx in the front. I will keep my weber! 240sx Throttle body for sale.... $50 you pay shipping I'm going to put it on e-bay Sunday. Quote Link to comment Share on other sites More sharing options...

big-phil Posted April 15, 2006 Author Share Posted April 15, 2006 I was looking at that too. Infact when I was at the junk yard this morning I kept saying to myself "please have a Q45, please have a Q45" I don't know where to get a weber?? I'd sell you mine for $146:wink: so I can buy that one on e-bay But I don't think I have the ecu to handle 90mm:( Quote Link to comment Share on other sites More sharing options...
premo-s12 Posted April 16, 2006 Share Posted April 16, 2006 haha, RIIIIGHT. if by chance the next time your at the junk yard and happen to spot a VQ could you please see if the VG/KA/CA, etc TPS would bolt onto that throttle body? that would be a HUGE help as no one seems to know and my local wreckers never have one Quote Link to comment Share on other sites More sharing options...
The Woj Posted May 16, 2006 Share Posted May 16, 2006 Slight bump, but I found this on ebay. Not sure if it's the same as yours, but it sounds that way. Weber Big Throat You are looking at a nice upgrade for your fuel injected 280Z or 280ZX. This unit is called the " Weber Big Throat " throttle body which was designed for 1975 and later fuel injected Datsun Z cars. We all know that Weber is one of the top names for performance, remember the old 240z cars with triple Weber's? they were awesome. This Big throat throttle body measures 60mm vs the smaller stock throttle Thus allowing more air flow for your engine. As we all know the more airflow you can get into your motor, the more power it will make across the power band. It has a rubber adapter piece on the end with the clamps, the instruction sheets are also included but are a bit soiled. This " Weber Big Throat " looks great, it is offered with No reserve .

Hugh Posted May 16, 2006 Share Posted May 16, 2006 I've got a Q45 throttle body on my engine, and its TPS is not compatible with any other typical ones I've looked at. My SR TPS sure doesn't fit it, nor will a KA . I doubt the CA would work, either. Someone once told me you can use the RB20 TPS on it, but I have no confirmation of that info.. The Q45 throttle body is great because it opens progressively. Therefore when you apply light throttle, it doesn't fly open and send a huge gulp of air at the motor. However, I'm finding it difficult to adjust the TPS acceleration enrichments just right on my Tec3 to compensate for this huge TB. If you do get your hands on a Q45 TPS, be forewarned: The main TPS connector is the kick-down switch. The actual TPS connector is found on the little pigtail that hangs off of it.

Weber Big Throat YES That looks just like mine!!! The same thing! The bid is at $247!!!!!!! Oh my God!!

veritech-z Posted May 17, 2006 Share Posted May 17, 2006 The 90mm throttle body from a Q45 opens the other way from the stanza throttle body I'm using, so the tps is not compatible. I was looking at a single cam ka24 in an early 240sx, and it had the throttle flywheel on the opposite side of the throttle body from mine, which is why i went with the fwd throttle body in the first place. I can't say for sure if it works on the 240sx or not... Quote Link to comment Share on other sites More sharing options...
JSM Posted May 12, 2008 Share Posted May 12, 2008 YES That looks just like mine!!! The same thing! The bid is at $247!!!!!!! Oh my God!!
