103MM Throttle Body For The C5 Corvette

Katech has come out with the answer for C5 Corvette owners! Katech has released their 103MM throttle body made specifically for the C5 Corvette! Before now the only feasible option was to use a LS2 throttle body on the C5 Corvette but now the C5 Corvette crowd has a 103MM option that works with the stock PCM.

I’m running a ls3 from a 2007 5.3 . Plug and play harness $20 it works.

Not always and way bigger of a pain to tune if it does

[@NickHerAmerican]

Would the 103 work with a 102 intake? And also does it work with the 97-98 pcm? If so silver blade is getting punted into another state and I’m grabbing this one.

[@natewaddoups6708]

Were you able to get the car to run right with this throttle body? I've been struggling to get mine to do cold starts because it needs to move the blade about 15% before any air can flow through it.

Great information thanks

Hey bro had a question on the high ram , i have one for my c5 as well , what did you connect to the rear inserts behind the hi ram?

[@ProjectDirty]

One to brake booster one to catch can/pcv one to map sensor

Don't ever take advice from this clown

[@colemcmeans7809]

awesome. do you think there would be a gain in mid-low 2.5-4k range power if i added a lsxr 102 intake and tb? stock heads , 224/232 110 cam.

[@ProjectDirty]

I think that combo is going to be a 3k-redline

[@ProjectDirty]

The biggest gain is the throttle response even over my old silverblade

[@colemcmeans7809]

Man that alone is worth it, I hate the sluggish feel of the stock one.

[@ProjectDirty]

@@colemcmeans7809 for sure if you’re still on the stock throttle body it would be night and day with a fast 102 you’ll have to grind on the water pump a little so it fits just a heads up

[@colemcmeans7809]

Did not know that,thanks. Wish they weren't so expensive, need to spend that money on wheel bearings right now anyway dammit.

[@randytwobulls3411]

Sir, does this bolt to my stock intake manifold

[@ProjectDirty]

If you’re talking stock c5 intake then that would be a negative
