MJ'87 Posted January 30, 2008 Share Posted January 30, 2008 i've noticed that TBS in the catalogs say '91-'02 2.5 liter :nuts: whats the difference? will it work on my '87? if not, is there some custom fabbing that can be done to make it work?

Pete M Posted January 30, 2008 Share Posted January 30, 2008 Waste of money either way in my opinion. :( Link to comment Share on other sites More sharing options...
tjbliley Posted January 30, 2008 Share Posted January 30, 2008 won't work cause it is only for a MPFI, not the TBI. Link to comment Share on other sites More sharing options...

SuperWade2 Posted January 30, 2008 Share Posted January 30, 2008 Waste of money either way in my opinion. :( :agree: I have one on my TJ and the only reason it's still there is because I tossed the stock length bolts and have been too lazy to go find new ones... Spend your money elsewhere! I wish I had... I do have a nice annoying whistle due to the TBS, but otherwise... SW2 Link to comment Share on other sites More sharing options...
FxRacing282 Posted January 31, 2008 Share Posted January 31, 2008 maybe if you bought like 3 or 4 of them, youd make a difference Link to comment Share on other sites More sharing options...
DirtyComanche Posted January 31, 2008 Share Posted January 31, 2008 They're supposed to be 3HP each, so if you got 4 that'd make 12HP. :roll: Scam. Link to comment Share on other sites More sharing options...

CWLONGSHOT Posted January 31, 2008 Share Posted January 31, 2008 throttle body spacers ...are wasted money. Well... yes and no. To just throw one on and expect tremendous HP gains. I completely agree with the others...NO. Unless your doing something to your fuel delivery system and your exhaust system. You money is better spent. As part of a complete system, Yes. That's different, then they have merritt. If your gonna have a free flowing exhaust, tubular exhaust manifold (s) open up your ports to gasket size and maybe even a cam upgrade. Definitely, followed by a larger TB. Then YES the spacer will add a bit. Even then, this kind of upgrade only really help with freeway driving speeds, I mean close to WOT acceleration. I put one on my TJ and other than the whistle didn't notice much. Later on, I upgraded to a Banks header and 2.5" magna-flo exhaust, 60mm TB and blended intake manifold. I noticed a much improved top end. Again, the differences where noticed when I tromped on it or when passing on freeway. Ultimately, you will have to decide.

CW I'm going to have to side with you on this. There is a time and a place. I would swap a '99 and newer intake first. I have the Borla header a highflow cat with a 40 series Flowmaster I also run the 60mm TB. The intake and cam upgrade would work great ith the above mods.

Confedneck Posted February 2, 2008 Share Posted February 2, 2008 yeah, tb spacer is not a waste of money, for those of you who said it is, how many of you had carb spacers in the 70s when you were like 40 years old on your mullet-mobile fbodies? same principal... turbulent air helps to atomize fuel better.... you won't get instant power gains, but with a bigger TB, freeflowing injectors and better free-er flowing exhaust, it will work Link to comment Share on other sites More sharing options...

Wooden ones do a great job of keeping the carb cool when combined with a heat shield. I never owned an f-body. I had mainly old Mopars like a '71 340 4 speed 'Cuda, a '68 440 sixpack 4 speed Roadrunner, a couple of 340 Darts, a Little Red Express, a '71 340 Demon and a '69 310hp 350 4 speed & 71 455 automatic Cutlass. I also just had a '05 SRT-4 ACR that had 300hp and 390# of torque at the wheels. It was a fun toy too. Link to comment Share on other sites More sharing options...

TNT Posted February 2, 2008 Share Posted February 2, 2008 lol.... same principal, no? Not quite... it can help by changing the way the air flows and increasing the volume of air after the TB. A '99 intake is a better choice Link to comment Share on other sites More sharing options...
Pete M Posted February 2, 2008 Share Posted February 2, 2008 All I'm saying is that I need to see some 3rd party dynometer runs to even come close to convincing me. Even if it could possibly add hp, there are much better things to spend your money on. Link to comment Share on other sites More sharing options...

Even if it could possibly add hp, there are much better things to spend your money on. My guess is maybe 1 or 2 HP at best. Once you've built and stroked the rest of you engine then a spacer might be worth it, but it would need to be about 70mm. Link to comment Share on other sites More sharing options...
