Default So.......the old APS TT setup is FINALLY getting an update

History: 99 C5 Coupe, M6. APS TT and stock motor with supporting mods, 500/521 at the wheels. Ripped cam pulley out of camshaft, bye bye stock LS1. Replaced with Texas-Speed 377 CID LS3 shortblock, 317 heads, LPE GT2-3 Cam, Lonnies Double Pumper fuel pump. New power, 761/760 RWHP/TQ.

Sold car in Nov 2010. New owner upgraded to LG 70lb/min turbo's, FAST 102 setup, C6Z TR6060 and rear end, Ram twin disc clutch. Ran 202 at 2012 Texas Mile, 825-850 RWHP range at same 14-15 lbs boost.

Bought car back in May 2015. Left it alone save for C6Z brakes and CCW SP500's. Started randomly dropping oil pressure late 2016, classic oil pump check valve symptoms. Queue the teardown......very slowly. Life tends to stop things.

Until now. On order and deposit already paid, a set of Tony Mamo's MMS 235 NFI cathedral port heads, Yella Terra 10mm rocker upgrade, custom camshaft. Upgrading to a Melling 10296 pump with the softer spring. Gone are the 102 intake and TB as they were causing issues, coming in are a LS2 90mm and intake, both of which are going to Tony next week. Fuel system is going back to a 97-98 return style setup, which will have the rails modified for an OEM look to fit the LS2 manifold (yes, this will be the limiting factor, but it is what I was using on my 761 RWHP setup and it had PLENTY of headroom on 60lb injectors, and there are 95lb injectors on the car now). Ditching the 2006 powerbond underdrive pulley and going ATI. Relocating turbo scavenge pump return from the valve cover to the timing cover. Breather tanks from the valve covers being added due to smoking under 14+ PSI boost (was on a stock PCV with Norris catch can, just wasn't enough).

Hoping to get to 1000 RWHP. Still have A/C and all. The ONLY compromise the car has seen was the F45 deletion when the APS TT kit went on the car back in 2007.

Stay tuned.......more updates coming as parts start to arrive.

Not that there's any interest in this.....but the camshaft arrived today and heads were supposed to ship from Tony today.

Needs list:

timing cover with oil return for scavenge pump (relocating from valve cover)
Oil Pump
Gaskets
ATI pulley
Misc things I stumble across

Are you using the stock APS intercoolers? Be interesting to see how they do at the power level you are after!

No pics.......yet.........Cars half torn down in the garage already (been like that for a year now sadly), and the Cam is the only new part I have. There will be a big parts pic once the heads/rockers come in later this week.

Still utilizing the stock APS Intercoolers and have zero intention of switching to a FMIC. The APS units have performed well to this point, only giving up a marginal amount of heat soak when compared to similar set up FMIC cars. They're one of those things that if it becomes really necessary to switch them out I will, but I don't have intentions of just doing it.

Not really. They were the 70lb turbos LG was offering as an upgrade back about 7ish years ago. Not sure if they still do or not.

Some work today. Maybe more later.....who knows.



Baby steps. Little here, little there. Have a lot of engine bay cleaning to do along the way. May have a buyer for the old heads already so somewhat of a push to get them off the car now.

Still waiting on rockers, and the manifold/tb to come back from Tony.

So, it's been too cold to get in the garage for me (that's my excuse and I'm sticking to it). But.....after more talking with Tony Mamo.......I've ordered the following parts from him:

Ported Melling 10296 Oil Pump
Tony's custom lighter ATI Balancer
Johnson 2116LSR Limited Travel Tie Bar Lifters

We're also going to do a mod with the turbos. I have a buddy who is putting a twin turbo Coyote Motor in a 65 Mustang right now, and he built a couple of sumps for the oil drains off the bottom of the turbo. Excellent idea, so we're going to be doing a set for my car too it looks like. Just gives some extra room for the oil coming off the turbos to move to without backing the lines up.

I have a 4 day weekend coming up starting on Thursday and I plan to have the motor opened and stripped, ready for new parts to start going in/on by the end of the weekend.

Bigger stuff starting to come out now. All the oil residue under the car is from a intake line for the scavenge pump. It wasn't tightened all the way when I got the car back a couple of years ago and really made a mess of things.

Ugh, one down.



Maxed my jack out getting the front just high enough to get everything wiggled out. Not looking forward to the passenger side......that one is going to be worse I think. Going to try to get that one tackled tomorrow.

Man those are baby little turbo's.

Finally got back on it today. Had to get the cam out because I had a local buyer. This is how she sits now:



There's a LOT of cleaning under the car that needs to be done, mainly oil residue from the scavenge pump return line that was leaking. So I have some serious scrubbing to do while there's room.

Expecting my last couple of boxes from Tony Mamo next week.

It looks like you have a worm clamp on the line for the scavenge. I would strongly recommend taking that off to put a proper -AN fitting on there. That should help a LOT.

. That's exactly what's being done. One of those was loose when I got the car back and was making an oily mess under her. I'm moving to custom built sumps on the bottom of the turbos and then -an lines to and from the scavenge pumps, then relocating the return fitting to the timing cover and off of the valve cover.

Expecting big boxes of parts to be delivered today or tomorrow, and have a buddy coming by Thursday to check the deck height so we can get a correct set of gaskets ordered (yours truly is ashamed to admit he doesn't own a dial indicator).

One step closer! This is a pretty solid parts list IMO and I just want to say that I feel very fortunate to be in a position where I'm able to do this in this fashion.

What you're seeing is:
Mamo's 235 NFI heads w/machining for 10mm YT Rockers
Yella Terra Ultra-Lite 10mm rockers
Yella Terra valve cover spacers (thick gasket)
Johnson 2116LSR lifters
Mamo rebuild and ported LS2 TB
Mamo ported LS2 manifold
Mamo ported Melling 10296 Oil Pump
Mamo custom Camshaft
ATI Balancer custom defined specs from Mamo
And a very expensive T-Shirt!
(the big box behind everything is a new rear section for my LG Big 3 Exhaust, one of the mufflers puked it's innards a couple years ago).




All I need is gaskets, redo the oil scavenge system for the turbo's, modify timing cover for oil return, modify 97-98 return rails to fit LS2 manifold. That's literally about it I think. Subject to changes.

You don't necessarily need sumps under the turbos if you use good banjo fittings and -8AN lines like the APS C6 kit. I run oil restrictors to my turbos (GT3076R in the C6 kit), roughly 0.030" if I recall, which keeps flow volume reasonable and the scavenge pump is always able to win. I recently switched from the electric pump to a mechanical one, but that isn't absolutely necessary.
