Default 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 hear it hurts performance more than it helps. 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.

really? maybe JUST a TB is pretty pointless but I have a feeling your talking the whole system.
Not like a FAST 90 can give up to 20hp over an LS6? 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

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. Theres many many out there,this one is just currently going at the moment

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 was more suggesting a FAST 90 or 92 (prolly around 800 for a complete setup) They're not made anymore but they pop up from time to time.

But if you can't do that then have your LS6 intake ported along with your TB.

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

"really? maybe JUST a TB is pretty pointless but I have a feeling your talking the whole system "
??? what ? have no idea what you are saying ?????

"Not like a FAST 90 can give up to 20hp over an LS6? I guess that intake is just for larger cubes? 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. "

The forum is here for posters to ask questions and to get "OPINIONS" from others on how to correct issues or on making mods---Thats all I ever give is my opinon--It's up to the poster to draw his own conclusions from anyone's opinion
However --when you say YOU are here to "correct info out there" specifically my opinions--- and to give "reassurance"-- You are discounting anyone who dis-agrees with you---That is arrogant

"Theres many many out there,this one is just currently going at the moment "
Many many WHAT out there ???? What's currently going on ?? This makes no sense at all----LS2 T-body on a LS1 !!!! remember ???

Default Time to teach :)

Ok I was nice at first because I didnt wanna come off as an a$$(Hence why I put in the "not to belittle you and the )

But since you're going to quote and exclaim like a belligereant child, I will proceed to treat you like one, and walk you through this post, quote by quote.

I said, maybe JUST(meaning only one) a TB (Throttle Body) is pretty pointless, but I have a feeling you're talking about the whole system(Whole system-being the induction system). This is composing of the TB(Again, Throttle Body) and the Intake Manifold itself. I did not say the OP was talking about the intake manifold. I knew what he was asking. You suggested the need for bigger cubes to justify an throttle of that size. You didnt even consider that IF there was a change in the cubes, You need to change the intake as well if you'd like more power and less restriction(I hope this isnt too obvious). Had you comprehended my sentence, spent more time trying to figure out what was said(truly sorrry you have to) ,this explaination would have been avoided and you could have understood that by your inferior thought process of "cubes and JUST(Again, Only one) a TB change", does not make sense. Therefore the reasoning for my assumption of you talking about the whole system(TB an Manifold) is accurate.


..Moving on, please keep up..

Had you understood my first sentence,and typed your own well-thought-out sentence, you would not be asking this with another ton of question marks and exclamation points(like that child I referenced earlier )

In this Quote, we have a grave error in knowledge and personal experience, being that you are a "Tuner" makes me estatic that your on the other side of the US,staying the hell away from my car...

By reading this statement your telling me(and any person who reads this), that in your opinion(), If you DO NOT HAVE BIG CUBES, it is a known fact that "large" manifolds( like the FAST) will hurt bottom end TQ, or make gains of 3-4 RWHP?

Your joking right? All day, every day, ANY DAY, these intakes make 15RWHP+ (please read these

New Numbers:

If Converter was locked could be looking around 465-475rwhp easy, but didn't want to stress out the verter and tranny.

Old Kpa:
74Kpa at Wot after 5,200rpms

New Kpa:
100Kpa at WOT up to 7,000rpms!!!!!!


So yes I believe this new intake is BAD ASS!!!!

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.

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 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.
