MRC - you gonna have this car at Englishtown on the 22nd? Would love to see it run...

 

Wow!

Great work.

 

YUP....LOL

 

Sorry forgot to ask, but what size turbo and what trim is the turbo. Also what is the a/r ratio on it as well? And are these the turbos found in teh APS base kit? Thanks in advance.

 

Yep...We did.








MRC, great numbers.......... impressed, and happy to hear that others are getting up there in the upper-HP range as well.

Stock sized APS turbos...APS never relaesed the information on the exact turbo specs.Supposidly they are custome sized turbos made by Garret specifically for APS.

 

A possible dumb question coming...Since the Unichip maxes out at around 11-12psi (I think), how much whp increase could I expect by just adding these heads to my build? Once my build is complete, I want to start out with the Unichip first and then eventually move into the Utech or F-con and the extreme fuel system by APS.

 

The heads and cams combo are good for at least 140whp .with proper tuning more.. Of course to handle that extra power your going to need a better fuel system such as the APS extreme.The whole thing with the heads we offer are that they make the engine that much more efficient with lest boost levels. The more power you can run with the less amount of boost the better. For example a motor running 500whp on 11 psi is safer than a motor running 400whp on 15 psi of boost, to put it simple the less boost you can run and achieve the same HP the better it is. Most guys spend their money on making their cars handle tons of boost without paying attention to making the motor more efficient flowing. For the cost of sleeves and labor of sleeving a block I would opt for headwork instead.

Exactly, that's what I was asking. That confirms for me not to sleeve and go instead with better studs and overzealous' SVR headbolt kit.

So, is it correct that the Unichip will only boost to 11-12psi or what's the max you were able to get out of it? At what point would I need to go with the APS Extreme fuel system? How much whp could I expect to get or max out with heads, cams and still staying with the Unichip and fuel system included in the original APS TT kit? I'd like to take this in stages.

 

Thank... I was just curious if you had to grab bigger turbos or mess with the a/r at all. This totally slipped my mind, but what did you do for a Mass Air Meter or did you convert it to blow thru? I will have to call you or my brother will, who do we ask for at the shop?

If Infiniti isn't going to fix my motor(I am burning oil bad... figure it has a bad oil control ring) I will be fixing my motor on my own and would set it up for this APS kit and buy the APS turbo kit from you with the larger down pipes and anything else you modified. Your build has impressed the hell out of me

 

I don't see the Headgames heads on your online catalog yet. Do you expect to add them soon?

 

Very nice. Makes you wonder what the results would be with this kind of head work when paired with something like the Stillen SC or anything else pushing lower boost at 6-8 psi. I think I'll have to come visit you guys when I'm on vacation in August.

 

We will be keeping a set in stock in the future for fast turnarounds.Right now were offering them to in house customers that wish to wait, but in the future we will be able to ship them with a core exchange.

 

We still use the MAF for part throttle driving.We have the UTEC tuned to speed density mode. Also Im not sure about the uni-chip maxing out at 12 psi, maybe the stock map APS has is only mapped for 12 psi...Dont really know, never pushed the UNi-chip past 12 psi, we took it out a long time ago to go with a UTEC.
