Now this makes sense .... buy a 50 k plus car ( up here they're 75k ) and put some unproven kit into it just so you can cause yourself frustration , hassle, growing pains , plus some possible additional costs . There is some degree of it with "proven " kits , nevermind the unproven . Can you say yikes ? As for just writing a cheque for their TT like thats a bad thing , feel lucky that you can, because the reality is MOST people cannot afford 100k + car and if this is the case , things must be going pretty good for you. Enjoy it. And good luck with your choice.

Totally uncalled for, Bill. If you don't have anything nice to say.............

 

Thanks for the tips Bill. Since I don't have the $$ at present, I will wait for A&A TT system and I'm not in a big rush. I personally like the over the top systems.

 

Thanks Dan
I am very excited about this new Turbo
I have done alot of research on turbos and these guys have it going.
They know what they are doing, So no one is going to change my mind
I am going to keep everyonr posted on my progress, I will be doing most of the work myself, Well me and my mechanic
I will also be posting Pictures of our progress.
Have A Great Day

That was kind of my situation. At the time I didn't think I could afford to both buy my car and send it to LPE for a TT setup. But in hind sight if I was to include my labor it would have been easy in achieving $30-40K in mods.

As it is I have only spent about $20-25K (in mods) between 2 cars and 3 different power adder kits and some H&C setups. Not too bad because I was able to sell everything for about .75-85 cents on the dollar.

You cost things out...pick a kit..any kit...lets just focus on a price for a Turbo kit and split the difference of the DIYer prices to arrive at $8k for a Turbo kit.

Turbo kit $8K

Forged motor $6K Depends on HP goal
(long block LSx) Subtract $3k for H&C
Stock Crank, H&C and stock bottom

Clutch $1K

Fuel System $1K
Fuel Injectors, Pump
Return system
Miscellaneous $500
Tune $500

Subtotal (no installation) $17k ($14K stock bottom)

Now you have to figure what the install is going to run. A diy'er can stay under $20K or $15K depending on whether you replace pistons or not.

If I was only going with 9-10#s, I wouldn't bother replacing pistons until a time arrived when I was forced to. You can effectively lower your CR down to 9.2:1 (approx) with a larger CC heads.

I hear people on here stating that they are running their stock bottom end with a "safe" tune..I find that comment hilarious....whether you are stock bottom or not you should be running around with a "safe" tune.

Having a stock bottom end vs. having forged pistons doesn't necessarily mean more power at the same # boost, it just adds an added level of reliability, in that it provides some cushion should detonation occur. Plain and simple.

An example, LPE for a long time has been giving full warranties on their TT 550 setup...and it is stock bottom, they merely used larger CC volume to lower the CR.

I used a stock bottom end with my Procharger setup at 12-13#s, stock Heads, and a mild cam. Ran great...for awhile. It was right at the time (beginning) of the introduction of aftermarket FPs..which I didn't own. I was using the stock FP and an inline pump....it leaned out. It only takes 1 or 2 times detonating with stock Hyperuetetic pistons....kaboom!

So after that I went with forged pistons and rods, but kept the stock crank.

Bottom line is you can make 590-630 rwhp with a stock bottom quite easily, and a few guys have made more (Quicksilver) on a stock bottom...if everything is working correctly and there is a certain degree of reliability of everthing working as it should all the time. That being said, any error at those hp levels (detonation) and you can kiss the stock pistons goodbye..they just can't take any abuse..too brittle..never were intended for NOS or FI.

By the way..the only frustration I had was with ATI and some promises made by a Vendor selling the TTi kit. The ATI frustration was very brief with me about 4 years ago and the same issues lasted and came up until just recently. I had the ATI kit for 6 mos...it evolved into the first A&A kit..which followed after many discussions I had with Kenny from GWP.

The most frustrating experience I have ever had with adding a power adder to my C5, in fact I was first approached and asked if my car could be the donor car..and I said yes. The kit did not deliver what was promised to me and what was supposed to take 6 weeks took 9 mos. After I got the car back I took matters into my own hands and was not able to achieve much better results...I picked up 10 more rwhp at a lower CR..so not a total failure.

But it was largely due to some promises that were made about the product..that really were not backed up in the real world...but I was willing to give most reliable tuners the benefit of the doubt...I did..and as a result...a much better kit is available and people seem to be quite pleased about it...so a happy ending.

On the opposite end of the spectrum is the kit I have now. Which took 6 mos to develop from beginning to end.

 

Someone hasn't been paying attention ....Big Cubes + T76GTS + 3" DP = huge back pressure issues at higher boost pressures. Try it if you want, but I have seen the results of the above combination. For this reason I am switching to a twin turbo setup (packaging). My single makes great power on stock cubes, but going to a 4XX motor with my single setup would not be a good idea. You will need at least a T88 t4, preferably a T6 to make good power efficiently.

 

You know I am sure that you will hear different thing from different people. But On single turbo's Earl not only knows what he is talking about............he has done it.

 

hehehehehehe....... 50k

check this out!
got a friend who is serouisly thinking about using his car a donor for new turbo kit. cannot say who the company is at this moment but should be VERY intresting, to say the least.
oh yeah the car LAMBORGHINI MURCIELAGO.
