L99 To LS3 Conversion

[@mohammedal-maskary8202]

sounds about right .... i got 477 whp 450 tuorqe on l99 using Titan King Comp cam stalk intake swapped into 6 speed f body

[@jasonalward4720]

I put 2” LT’s with no cats n muff delete, mannnn I live I a quiet town full of Karens, I drove it like that for a few days then put hi flows on. It was crazy loud til I piped it down some w the hi flow cats, even still. Idle n under 3-4 k rpm is cool. When I put my foot on the bell housing, it tends to make some real noise. Everybody always asked me what I got for exhaust on my car. I just tell him two inch long tubes, high full cats and straight pipes and it sounds so good not having to spend all that money on some thousand dollar Cat back system all I did was bought a tailpipe Set! Good to go!!

Another great video, Matt. Thanks

Excellent RWHP numbers. I have a L99 converted to LS3 but mine is running at 433 rwhp. How did you manage to get it at 460? Here my current mods.

He’s running a ported throttle body a different manifold and his car doesn’t have vvt

[@willbutler2639]

Maybe because this car in the video has a different (edit-manifold) intake. Is your intake stock or the same as in the video

[@cj8172]

Great video. I may be buying a L99 2011 Camaro which aparently has had the computer "flashed" so it's now full time V8 and no V4 fuel saving anymore. Do they last ok having this done to them and is it a good idea?

[@isnowyazn]

I’ve personally had no idea since I’ve never had an L99 (6AT), only an LS3 (6MT). But on a somewhat unrelated note, I know I have a V6 Accord 6AT that uses VCM (variable cylinder management). It greatly reduces the stress on the hydraulic motor mounts, which are mainly used for the AT model cars. It of course eliminates fuel economy, in trade for more active power and throttle response. Some people have also had carbon buildup and other oil leak issues from the cylinder deactivation. But deactivating them solved MOST of those issues, but not all, as always..

I disabled dod on my l99 and I’m at 235000 miles

[@realshidd3062]

What are the cam specs?

[@sdelarosa080]

What happens if you swap out the whole engine and put a full assemble ls3? Does it need a tune?

[@KeepSycklids]

I'd like to know as well

[@clarkweber3553]

Are you in Indiana? Definitely an indiana plate on it.

[@johndale8614]

Maybe let your subscribers know the price for doing this. I too have l99 2013, with only 6700 miles. Very interested.

[@olveramelinda]

If you have parts 3400$

[@kevinjack1171]

How much did this cost? I’m interested in going through you guys for this same conversion. Also have an auto with 94k miles

[@olveramelinda]

Me too I’m at 109,000

[@beepbeepbeepgo2122]

25k here l99

[@nevertrumper7030]

If you’re going to do this keep the VVT

[@_SlickRickSS]

Great 👍 informative video Matt , what would be the invoice 🧾 estimate on a job like this sir?

[@rydawg3782]

about 3-5k

[@pwr27986]

10K

[@willbutler2639]

Good work inst cheap work. I would have to say at least 10k because he took the trans and motor out. He said he took the block to a short block to they did a ton of work. It was probably also re ringed, bearings and all that good stuff. It was an old girl 94k. If it was mine and he was already in it I would’ve almost rebuilt it.

[@michaeldyer6304]

How don't you have more sub's....

[@ApeMotorsports]

Lol. Not sure. Maybe I don't blow up enough stuff or not enough burnouts.

[@Akwardturtle]

He just got another sub, only because I'm in the market for an l99 camaro and he popped up.

[@pablovelasquez7449]

Where are you located at , im interested

[@xvidavi6090]

Is it worth swapping to ls3 ?

[@ApeMotorsports]

We do these conversions on l99's to make the valvetrain more reliable with bigger camshafts. The stock l99 lifters can't handle the increased valve spring pressure with the stiffer springs we install. The stiffer springs are required with the higher lift cam.

[@lamarwilson6840]

@@ApeMotorsports is the autos strong? Say for LSA blower or turbo on the stock block?

[@ApeMotorsports]

We have quite a few customers with 700whp on stock 6l80's still going strong after several years. It's all in the tuning.
