LS2 DBW Throttle Body on an LS1?
Anyone running a LS2 DBW throttle body on their LS1? I see they make adapters for mounting and corvette central sells a wiring conversion. Im just seeing what everyone has done and if it has any benefits? Let me know! Thanks

WHY ?? No real benefits from going to a larger T-Body UNLESS you have:
Larger than stock cubes--Consistantly run it above 6200 RPM's or have a Huge cam You would however benefit from getting yours professionally ported which adds 3-8 RWHP and greatly improves throttle response-- |
i will be doing a head and cam package (Cartek 3x heads 2x Cam) with a BBK intake

Plus you will lose some low end torque. Why not just get the stock one ported and polished? I could tell a difference in throttle response. |

I guess that intake is just for larger cubes? Huge cam doesn't mean anything even an intake/Tb is good for mild cams. And the "pull" from the power gain is throughout the powerband(not just above 6200rpm) FAST doesn't choke out as early as a LS6 either. OP read up on this bud, go with a FAST intake if you have heads,cam in your future build :thumbs: http://ls1tech.com/forums/7248658-post10.html Tblu92, not to belittle you by any means, just want the correct info out there, and maybe follow up on this thread to give you some reassurance to what I said.

trible black: I agree the FAST stuff is good but not good enough to drop $1k+. Plus with all the complaints so far about their new 102 and the fitment problems on the C5. Im not going to try and give them money. Their solution is to cut the car or shim the cradle who the hell says that?
So pretty much stick with my plan and get a stock unit ported and polished? Dont worry about getting a fancy t-body unless its for a steal. |

I'd get your LS6 intake modified by TPIS to accept a 90mm ported throttle body.

Huge cam doesn't mean anything even an intake/Tb is good for mild cams" Who said anything about a manifold or Fast?? Not the poster--He asked about putting a LS2 TB onto a LS1 engine--that's all !! " And the "pull" from the power gain is throughout the powerband(not just above 6200rpm) FAST doesn't choke out as early as a LS6 either " Not True---IF you dont have the airflow of larger cubes or high RPM's it is a known fact that large manifolds ( Fast-TPIS etc) will hurt bottom end TQ. or will make only small gains-- less than 3-4 RWHP-- And the "pull" you speak of is Torque on the bottom end or mid range--NOT the top end horsepower---TQ is made with manifold port velocity and a large manifold KILLS port velocity and reduces TQ far more than the way it reduce HP on the bottom/mid range "Tblu92, not to belittle you by any means, just want the correct info out there, and maybe follow up on this thread to give you some reassurance to what I said.

i gained 20 rwhp and 17 lbft going from ls6 with ported throttle body to a home ported fast 90/90 setup.The midrange gains were very nice also

I just did a back to back dyno from a ported ls6 to a ported Fast 90 and picked up 13rwhp and 10 rwtq after retune. There was places in the graph where it picked up 14-15 and it carried the power longer. Was a definite difference from the sotp too.

I picked up 27 rwhp going from a Stock TB/LS6 intake to a 90/90 Fast intake non ported. The more you have done to the motor the more power you pickup.

I picked up 14rwh/17rwt with a Fast 92/92. Bolt-ons and a 226/230 cam before the swap made 400 at the rear.

Dyno's compared: Old Numbers: 413rwhp/ 403rwtq on a Dyna Pak(which tyipcally read on avg 10-20rwhp more then a dynojet) with Converter Locked New Numbers: 427rwhp/ 371rwtq on a Dynojet with Converter UNLOCKED!!!!!

You seem to know a lot about FAST intakes young man. For someone with that much knowledge, you could not install your own correctly.......:ack:

If your motor is out of an '01-up Corvette/F-bod, you already have the LS6 intake manifold, which is superior to an LS1 from 2000-older. If you want to run a BBK manifold, I would suggest against it, if you have the later manifold. Actually if you haven't already bought it, don't. You can pick up a take-off LS6 manifold/TB combo that'll work great with a H/C motor, but I'd look around for a FAST90 (Preferably ported) that is made for the 90 TB. Much better performance than all the other alternatives. Be patient, and keep your eyes open, they're available from time to time. I sold mine, with TB, and conversion harness a couple of years ago for about $600.

LS1 vs LS2 throttle body
http://farm7.static.flickr.com/6087/...9a7565a8_b.jpg LS1 (left) vs. L92 manifold comparison (same size as LS2). http://farm7.static.flickr.com/6072/...b92fb8d6_b.jpg |
I'm starting to wonder if a heavily ported LS2 intake can be the "NEW FAST 90"
Hmmm I'll ask Tony |
The Motor (and drivetrain) are from a 2000 C5. I was basically looking for direct info from people that have done this swap, not a hijacking and people pushing the overpriced fast stuff. Since the :boxing match i stopped paying attention to this thread.
blu00rdstr: Thank you for your input with pictures, this was the stuff i was looking for as you can see there is a HUGE difference between the two. I was hoping to pick up more power and flow from a simple inexpensive bolt on. I applaud you for sticking to the question at hand. |
