T3/T4 50trim
3" exhaust
+20 injectors
12psi
... Just a tad slower than a Stage 2 SRT4

Next up:
Modded cal
+40 injectors
17psi
... Target: 330whp

Then I throw on a front mount and crank the boost to 20psi. After all is said and done I'm looking for close to 400whp.

Supporting hardware:
Wideband UEGO
Adjustable fuel pressure regulator
Walbro
3 bar MAP
Boost controller

I'm following the Wallace plan for power, Just have to wait for him to park in a dark spot:thumb: Seriously though, I'm thinking A lonewolf stage 2 port with stage 1 cams A trim-cal with 72# injectors & a beautiful holset waiting to break things:cool:

Think traction as well, all the power makes a nice smoke show, but gotta get it to the ground...
WORD! Extra power is useless unless it can be put to the ground, SOOOOO.... First thing I'd personally go with are all mounts supplied by PolyBushings (available at FWD-Performance also).

Hell I'm traction less now on the street with filled bushings with the stock setup. But a least with more power you can pedal it in to the 12's:laugh:

welded head w/ three angle valve job; full turbo back 3in exaust w/ cat and magnaflo muffler; stage 1 ECU; +20's; RFL BOV.

Next mods include front and side air bags (ya right) LOL ... front and side engine mounts from Polybushings, rear sway bar, rear adj koin's and a phanthom grip lsd

Then hopefully a new turbo (I'd like an s-70) FMIC; bigger injectors and bigger fuel pump. also probably will need a reflash of the ECU

There was one in the f/s for a month before it sold, you should have grabbed it. Everything I've read about the s70 did not sound that promising over the stock TIII snail

If your looking for a no hassle replacment and a little more power. If you can get one for a good price, its worth it. Now, if you have to pay full price for one. Save your money and go with a hybrid.

I have had my Spirit R/T running for a while now since I got the car put back together after sitting a few years. I did some mods to it, but mostly to fix problems the car had already had before I bought it. Had broken motor mounts, bad trans, extremely clogged exhaust system, a broken rocker, bad lifters etc etc..it's running pretty good now that I have fixed most of the major problems but I am still working out some bugs with the setup. Here is the mod list:

Shortblock: Balance shafts removed but otherwise stock.

Transaxle: A568 rebuilt by Cliff Ramsdell with 3.50 FD and OBX limited slip differential.

Cylinder head: Stock casting with valve job done by Lonewolf Performance. Titanium valve spring retainers. FWDP new redesigned lifters. LWP Stage I cams. Dry film treated cams and rocker shafts. FWDP adjustable cam sprockets.

Manifolds: LWP ported exhaust manifold thermal coated in/out. Stock intake.

Exhaust: 3" FWDP cat-back kit, 3" downpipe, no cat, Dynomax Ultraflo muffler.

Fuel: Walbro 255 ltr/hr in-tank pump, LWP fuel rail, Accufab AFPR, Russel inline filter, 3/8" aluminum hard lines and 6AN braided S/S flex sections. Modified sender for 3/8" in/out of tank. Also MP +20 injectors yet to be installed.

Other: Tial 50mm BOV, KN drop-in air filter, FWDP underdrive pulley, McMaster-Carr vacuum distribution block, grainger valve boost controller, Autometer A/F and vac/boost gauges in Lotek A-pillar pod, OTC 4000E scanner, 16" GTC lace wheels and Kumho 225/50/16 tires, FWDP braided S/S brake line kit, Polybushings.com motor/trans mounts, Magnecor spark plug wires, NGK BR9ES spark plugs, FWDP aluminum valley cover, powder coated black valve covers and intake manifold. OK I'll shut up now:rolleyes:

Next mod: Innovate Motorsports LM-1 wideband.

You might want to add a big IC to that list. The stock IC is a big restricktion at that boost level. Check out my car domain page for IC mounting options. I did not do the work, but It will give you and idea of what you can do. http://www.cardomain.com/ride/2258018 Also you may want to search on this board about udp. I think some have had problems with them. Personally I would spend my money on something else. Just my opinion, but opinions are like ...holes everybody has one. :)
