APS will be releasing the Twin Turbo for the G35 before they release the Single Turbo. The APS Twin Turbo has been released for the 350Z and there has been good feed back about how complete and strong this kit performces. As many of you out there I'm also gathering as much information as possible before I decide which kit to choose from. Please post if you have any information or questions or thoughts about this kit.

 

Here's a couple guys with Zs who have the APS TT...

I had about 13k on Zippy. I bet dollars to donghts that over 65% of them were on race tracks, or getting to and from them. I put the Twins on in December just before Christmas,and in Chicago during the winter, my Z does not get much action. However, after getting it out a few times on unseasonably warm days, I can say I now know what a crack addict must feel. OMG is it sooo awsome to drive. Tuan @ GRD did a real nice job of tuning it. She is at 443hp now and we are lookign to go to nearly 500. I would be very happy in the high fours, but 500 would be Sweet. The long term goal to to build as bullet proof a car as possible with all this new HP. Like adding oil and differential coolers. A dry Sump oil system would be the ultimate!

I will be getting the bottom end done by GRD and Tuan by the end of the March. Can you say 500hp?

I have the APS TT kit on my stock internals 350Z roadster. the only other mod is Nismo exhaust and Helix test pipes. The dyno test result you are referring to was run at time of installation after tuning for 7 psi and 91 octane gas. I have had some additional fine tuning done since then at 8 psi. Attached is a pic of this latest test showing 414 rwhp.

505whp stock motor APS TT kit 93 octane

Just did some more playing around with the APS TT kit on our car. I wanted to see how far I can push our stock motor with the APS kit on 93 octane. Ran boost a little past 11 psi and she ended up making 505whp. Fueling became an issue at that power level and we aren't exactly sure why just yet. We do have an assumption already and will hopefully address it on the next tune.

Chart shows our stock car baseline HP in solid green, boost in blue and TT HP in dotted green. I didn't want to spend anymore time with it until we get the fueling resolved. I had planned to take her home with me tonight to take it for a spin but weather man says its going to snow.

Cheers,

Tuan Nguyen

 

505 on stock internals? wow.

 

how much will this cost?

 

Hey Peter,

Can you give us some more information on this kit?

 

I believe the kits for the Z are going for roughly $7,500. So the G35 kits have to be in that range.

 

If you buy it from Tuan, he can send you the kit pre-tuned. I don't know how much he charges. You can find him on 350zmotoring.com

It is possible that some of the AC line "may" need to be re-routed/replaced on the G kit to make clearance for the FMIC pipes, hence it may cost a little more than the Z kit. Also you need to factor in the cost of an open mount front bumper faica + painting. The cheapest version is from Stillen and it is Urethane=druable as opposed to fiberglass. Running the OEM bumper facia will provide inadeqaute flow over the FMIC, so this will be a must.

 

I've heard that this TT will be fine to push 400 whp with stock internals, nice. For those wanting to push 500 whp I'm sure you might have to upgrade the internals. This also has to work along with tuning which is important.

 

why would this be fine at 400 but not others?

 

Because they did their homework. Baffled oil pan, sheilded crank angle sensor, fuel return line w/ rising rate. A locked piggyback unichip controller tuned to 91octane. Greddy left too many pieces out of the puzzle, great system if you are a tuner. APS is more of a set it and forget it system.

 

Exactly!
The crank angle sensor discovery was a major step forward in FI on the VQ's!
I looked at the APS TT being installed on a Z earlier this week....and it was SCHWEET!
The techs at Z1 were raving about the quality and completeness of the kit.

 

Hey "OldVFRGuy" lol did I tell you I got to ride in that APS 350Z at Z1? I'm sold on it now so I'm anxiously waiting the release.

Peter from APS was on these boards but I dont think there is enough interest in FI for him to come over this way on a regular basis.

 

He may be around since my350 is down.

You 2 boyz better get back home?

 

We need to get Peter over here on a regular basis. Peter is a good guy with a lot of good FI and APS information.
