Hmm, thats strange...because i have a 95 Eagle Talon putting down over 500 whp on pump gas...but yes it did cost alot to get there

Anyone? After some snooping around, the consensus on pump-gas in the range of 450-500 RWHP. That seems a little exaggerated to me, but is there any truth behind this?

Is this a TSI? Because if it is, of course its expensive to make that kinda power, you have to compensate for the drivetrain loss of the AWD, the GS-Ts made power way easier. I spent a total of 12k to make 500whp, and its only "safe" running a fuel mix containing 110. You might make that power, but that engine will not last, especially if you have stock rods/pistons, the earlier 4G's were made of glass.

Back in 02-04 I worked at a prominent DSM shop outside of D.C. It was absolutely childs play to get to 450-500hp in a DSM without even lifting the head off the block. Problem is at that level you are tuned pretty close to the edge. One tank of sub par pump gas and you are toast. Good example:

Personal GSX stock longblock, t3/t4 setup on a 60-1 compressor side, AEM EMS, 720 injectors put down 469hp to the wheels without pushing it too much. I ran like that for almost a year on pump gas, but one night I must have had a bad tank... Hit a little detonation and the #1 piston decided to come apart, demolishing the shortblock, head, and turbo.

On the 4g63 the stock cast pistons are the weak link, a little knock and poof you are gone. We normally suggested our customers to go with rods/pistons at the 450hp mark, and if not turn down the boost on pump, and only run full boost on c16.

Even though I didn't do a LOT to my car to get to 469whp, I did end up spending around $7k, and did all the work myself and was getting dirt cheap prices cause I worked at the shop.

EMS: $1400
Turb: $800
Exhaust: $800
t3/t4 manifold: $300
Wastegate: $200
Injectors/Pump: $500
Boost Controler: $400
FMIC: $1200
Clutch/Flywheel: $600
Misc: $???

So although it was easy to get there...staying there in one piece without a little internal engine work was a little more difficult

Heck, my cost on rods/pistons was only $800, and could have gotten the machine work for another $200. For another $1000 I could have made that setup a completely reliable venture. Again, doing all the work myself.

If we were to do the install on all that the bill would have been around $3500....

So this 370z kit is VERY reasonable.

Words of wisdom. I was looking into buying another, but GSX's/TSI's arent exactly easy to come by.
