I am looking into purchasing some sort of FI for my coupe, but I was wondering if anyone knows what kind of power levels to expect from the APS TT and Single Turbo kits with Forged Internals. I was hoping for a streetable 500-550, and the Greddy is the only kit thus far I've seen making power levels above that. However, I was hoping to keep the Greddy as a backup option since I like how the APS kits are more complete and I've heard quicker to install?

 

The problem is tuning is limited right now with the APS kit. You're seeing more Greddy kits in that hp range because they can be tuned, but you're also seeing engines blow with the greddy kit as well. The one Unichip dealer I know of that can tune for a lower compression ratio and forged internals is grdperformance in chicago.

Out of the box the APS TT puts down around 380whp with stock everything.. the single seems to put down about 20whp less. You can easily add test pipes and a true dual exhaust and be in the 400whp+ range.

 

If you are going to build the motor with forged internals then you don't have to worry about your motor blowing up with the greddy.

I think the APS is a great kit but a big waste of $$$ IMO if you can't get it tuned to make more hp than what it comes with the out of the box. If you have a unichip tuner near you then go for the APS if not go greddy. You can make the greddy just as complete as the APS for the same price. You will need to buy a fuel return system, BOV, CAS wire, and boost controller to be as complete as APS. If you go this route you will have a better fuel return than APS.

 

Am I the only one that saw, "Forged Induction" as the title of this thread? Sorry, just HAD to mention.

 

Forged induction would result in forced internals

 

LOL, yeah I never noticed it till you pointed it out.

 

The base APS TT system is capable of around 520 WHP straight out of the box with just some additional computer tuning and the APS true dual exhaust system and test pipes.

Tuan at GRD has tuned his Z car to approx 511 WHP on the stock engine though at this power level I would recommend that you look into forged rods and pistons to ensure reliable long term engine operation.

With a larger fuel system (currenty being developed by APS) and the right cams and cyl head porting I believe that around 650 to 700 WHP will be the true potential of the APS Twin Turbo system, hope this helps.

Thanks

Unfortunately we don't have a Tuan in every major city. I would have been all over the APS TT is I could have had it tuned for more hp.

 

Gman, I completely understand that, though there's nothing stoping guys tuning an APS TT system using the same tuning method/technology they would on a different brand of TT system - I must admit though the entire concept of self tuning/road tuning scares me half to death though ultimately there is no reason why guys can't go down the self tune path if they're brave enough to do so.

Peter,

I am not talking about self tunning. I don't know chit about mechanics or tuning. I was refering to having an experienced performance shop to do the tune, like Tuan. Unfortunately when I was looking into the APS TT, I found out that APS only has one authorized dealer in Florida and they can't tune the unichip. I even called Unichip directly and they told me they are working on getting authorized tuners in FL but have no idea when.

 

Isn't the unichip locked and can not be tuned unless your are an authorized dealer? I was told in order to tune the unchip without being an authorized dealer that you would have to buy software that cost like $1000.

 

Gman, There's no reason why a G35 owner could not tune the APS TT system using some other form of engine tuning product - as people do with other brands of TT systems.

Peter

 

Correct, only an authorised trained Unichip dealer can tune with the product.

True though there's nothing stopping the owner from adding some other form of tuning technology/computer if they want to, the biggest problem that I see with regard to tuning is the lack of real tuning talent.
