Not many though enough to be comfortable with the entire fitment and operation of the system.

That's certainly a valid point you have and a oil catch can should be installed on any engine that has high crankcase pressure. Another product for APS to develop over the coming weeks/months.

Well let us know what you end up doing with your motor. I'm thinking of going with AFR heads now instead of ported 6.0L heads.

The install instructions have been amended to cover the removal of the coil packs.

Thanks,

100% correct.

I've not worked on a 02 model Camaro so you will just need to check items as you go..............I don't expect that you will run into many issues. Just take your time and ask other guys or myself if you run into a problem or an issue your not sure about.

The 2 vacuum hoses attached to each the LHBOV and the RHBOV and then attached to the T-Piece, does the third side hose go to the empty fitting on the steel T-Piece pictured in step 143?
Correct and make sure you read the instructions first as this is covered clearly in the install instructions.

Sounds like you know the Camaro and Firebird from back to front, thanks for your input my friend.

High power output really comes down to the right engine combination (engine specs) and engine mapping/tuning..............seems to me that the GTO guys are more organized (or maybe better funded) in this regard.

The C5 twin turbo system will quickly generate 800-850 rwhp with the right basic engine combination, fuel octane and tuning.

Good post Tony. The LS2 is certainly an improved engine combination though a forged 346 twin turbo engine with nice flowing heads, intake manifold and turbo cam will quickly make 800 rwhp.............on high octane fuel and with thorough engine tuning.

Peter

PS- How's the twin turbo GTO performing, you like?

A successful twin turbo install will provide you guys a load of personal satisfaction, there's no doubt about that.

I think you will see some 800+ rwhp APS twin turbo C5's in the near future...............I know that the guys at Cartek are building an APS twin turbo forged 346 twin turbo car at the moment.............there's no subsitute for pratical engine building and tuning experience.

Yes, this is the exact cam that we will use in our forged 346 cube twin turbo engine.

Do you want an engine that sounds tough at idle or goes hard right through the rpm range?

Great post Les, I guess it boils down to this, do you want personality or Real Performance?

I'll take Real Performance every time!

I'm going with 225 AFR heads and the LPE GT2-3 cam, hope that helps.

Excellent looking kit and very detailed instructions.

If you guys had advertised this 2 weeks sooner I may not have already blown the money on a prochager, which I still haven't installed yet.

The minute I found out about it, I was like.....dammit! And the kicker was, that I was actually in Austrailia when I sent the money out for the charger......Doh!

Good Luck to all those waiting and I'll ook forward to seeing some awesome results.

Yeah I saw that. If anyone can turn big #s and low time slips it is the guys at Cartek.

Whenever I get your kit, they'll be the guys tuning me

I went with a lingenfelter gt7 but after reading its very close to factory z06 cam not sure year of z06. Its got more ls1 than the gt3. The gt3 think was originally their turbo cam and think also good for supercharger but think the gt7 has taken place of gt3 for turbo applications. So Peter you might want to run gt7 like me. As for heads I was just going to run some patriot performance 72cc to bring down compression and they are cheap talking stage 3 with big valves as did plan on 408 or 427 down the road a bit. 225 AFR think are also more for 408 up type of thing and 205 AFR more for 346 and up to 400 or so.
But really think almost any cam within reason will work with the turbos and seems there are lots of ideas as to what works best with splits, reverse splits and various lsas being run. I could likely keep my current cam 221/221/558/558/ 114LSA old mti b1 cam as think it would likely do ok. But in my old age think want a cam with basically no lope in my twin turbo car. Rumpity cams are more at home with NA builds and supers for some reason. I want my turbo car to be pretty mellow until I unleash the dogs of hell. Turbo cars are great in this regard. Usually super driveable and then wild crazy power when they spool up. I have ridden in a 5psi sts lately in ls1 and one in an lt1 and both times at only 5psi it was still a rush. I am sure twins at 5 or 7 psi on bone stock engine will still also be a rush. I am also used to plus 500 hp in my 97 talon.

Well its good to see things progressing and getting close to delivery dates hopefully.
Excitement is building for sure.
