Will the more modern front mount kits overheat on track provided you have good ventilation?

True, but the second post asked about superchargers as well. Figured the conversation was more practically about forced induction power adders as a whole.

That's a very open-ended question, since usually the definition of "good ventilation" would be not overheating. So no, they won't? It's totally possible to keep a turbo car from overheating on track.

Fbm for big power and good customer service

Sbd for 300whp-ish on pump with good customer svice

That's my opinion though and the only 2 kits I'd consider. I'll be going sbd.

For my money the Full Race kit is the best available, if for no other reason because the EFR is the best turbo available. I also like the Full Blown stuff. I submit to you my argument - look at the torque curve. 30 PSI by 3500 RPM:

x2 I'd also love to hear the answer to this question.

i went with JRSC kit (twice as cheap) but if i decided to go turbo it would be PT tuning without a doubt.

Thanks for the info. That's indeed an impressive torque curve! What other mods do you have? Presumably this was a built engine. Lower CR? E85? Do tell :)

Why the 6758 over the 7163? Also, was this a twinscroll or single scroll? I like that treadstone has an EFR kit for substantially less than Full Race.. but as far as I can tell they don't offer a twin scroll option.

My ideal setup would be a very low front-mount EFR twin scroll with internal wastegate and an air/water IC in front of the engine (see the coyoda setup) using the mechanical oil pump... but no one seems to offer such a thing :(

I can sort of chime in on the ones I investigated prior to purchase. My purchase was based purely on the fact that I'm located in Australia so shipping and exchange rate influences my purchase greatly.

I ended up with an SME (Sydney Motorsport Engineering) kit which is hand made in Australia by Mike, and he has many different set ups, all using quality turbos. One form of kit is designed for race so it uses a different crash bar. All the others do not cut or change anything. My kit has about 15,000km on it and has had no issues with weld cracks, parts breaking etc etc.

If I was in America, I would have bought the Ptuning system. It is an awesome looking kit with heaps and heaps of good reviews. Seems to be made real solid. It does take a bit longer to spool up due to longer piping system.

From what I've seen of the AVO, and the review of everyone here in Aus, they are eh. Cheapest legit kit, but I'd probably buy an SBD kit before I bought AVO.

SBD now offer many different option turbos such as billet wheel, billet 9 blade and a ball bearing turbo. They are cheap but do the job and everyone who has one seems to be fairly content.

Looking at purely long term quality, I love my SME kit (bit harder to get in America with a lot of similar options), or Ptuning. Allows good quality headers such as Tomei etc or cheap ones that can do the job. Looooots of pipe work though making it more of a track style set up.

Oh and Eric from Velox swears black and blue by their Full Race system from what I've seen. He is one that does some serious, serious research and if he chose them, he chose them for very good reason.

I've done nearly two dozen track days on my PTuning turbo kit (series 1). Their series 2 kit addresses any and all issues that would be related to heavy track use. I've since upgraded to their series 2 components (stainless coolant lines, less wiring, less weight, better exhaust routing, better heat shielding, etc...).

Just talking about the entire turbo system, not the car and its heat/wear management.

Anyways to sum up your original concerns, here is my comments on the PTuning kit;

- Fitment: Spot on. A lot of piping to install but really straight forward.
- Quality: 10/10 I can't say much more than that. Not one component has broken, chafed, worn excessively during my track use.
- Performance: Series 2 has a bit more flexibility of turbo choice which gives you options to chose the performance you want.

I have 35,000 miles on my turbo kit, its been installed on 2 cars and like I said nearly 2 dozen track days on it. If you want to see first hand how it's held up, we're in the same County.

MAP :)

I just looked it up, does it come with everything needed? Appears to come with ecutek tune, license and cable, pre-welded oil pan and a new fuel pump. I have the greddy kit waiting for me to return from my trip to be installed. I'd seriously considering selling it and getting this kit.

Also does this kit require cutting the crash beam. I wish there were more info out there on it. Seems like a good kit for the price.

Appreciate the feedback. We truly strive to make the best products. Here is some reading material for those who are interested in our turbo kit:

Yup - built bottom end with lower CR dished pistons, rods, bearings and studs. Also an OS Giken twin disc STR clutch and an Xforce dual tip 3" exhaust. ID 1000 injectors, Fullblown rails, return system and Walbro 465 pump kit. Tuning, install and flex fuel kit by DD Performance Research. Also has an oil cooler and remote mounted filter. This tune in the video is the E85 tune. We are also using a 2 port actuator for the internal wastegate and a 4 port mac valve to control it.

The original goal was only 350 wheel for daily driving on 93. Wound up able to make well over 400 on 93, but dialed it back to about 380 wheel and we are using the ecutek boost control to raise the boost a bit on E85. Also have a detuned map for daily around town which has pretty scaled back boost in 1st and 2nd for traction reasons.

This turbo is twin scroll, and was picked because again - we were only wanting 350 wheel on pump with a very fun streetable setup. Wound up able to make a lot more than that, but we wanted fast spool with minimal lag, and this setup really delivers on it. We have done an STI fullrace kit with the same turbo and it has similarly impressive torque curve and power production.

My understanding is that it does NOT require cutting anything. The kit does appear remarkably complete for the <$5k pricetag.

I really like the simplicity of the EFR series turbos for a street application. I'm not looking to make huge power on a high-rpm built motor so having the internal wastegate and built-in bypass valve seems to greatly simplify the installation. The performance of the PTuning kit is also impressive with the GTX2867R turbo, but that kit is over $6k and doesn't include upgraded headers... Let alone an ecutek cable/license, fuel pump, etc... I figure at least another $2k to add those things. I know quality costs but I'm just not seeing it. I need to do more research though... and maybe find a local car with one of the kits before I make up my mind.
