well i raced my brother's R/T from a roll last night. you guys probably already know my mods. his mods:

- Lone Wolf Performance stage 1 reground cams
- LWP ported exhaust manifold
- Lotus 16v DOHC cylinder head rebuilt with valve job by LWP
- full 3" mandrel bent exhaust, no cat, 3" Ultraflo muffler
- M&M Racing grainger valve MBC @ 10psi
- A568 5-speed rebuilt with OBX (Quaife style) LSD and A523 3.50 FDR diff (it has "highway gears" compared to stock)
- FWDPerformance adjustable cam sprockets set at LWP recommendation
- Mopar Performance & PolyBushings.com motor/trans mounts
- Walbro 255 lt/hr fuel pump
- Magnecor KV85 spark plug wires
- FWDPerfomance underdrive pulley
- K&N drop in (stock airbox)

stock Garrett T3 turbo, stock sidemount intercooler (alot like a TGP intercooler), and stock injectors (i think).

we raced from a ~20mph roll on on the interstate. i immediately spooled up (his car has alot more lag) and put 1.5 car lengths on him while in 2nd gear and going into 3rd gear. while in 3rd gear he stopped losing ground. when i shifted to 4th gear he started inching up on me. at the top of 4th gear (110mph) his front bumper was at my B-pillar. i would have kept on going but i missed 5th gear!  :bash: i think he probably would have gotten even with me at around 117mph. i think his gearing and being 16v DOHC helped him start walking me up top, whereas my gearing and shitty flowing GEN-II top end was starting to hurt me (the opposite being the case down low). my car would definatey win a typical 30mph street race, but he would get me on the highway for sure. from a dig it's hard to say. i think he would get me out of the hole (since he has LSD) and then i'd be stuck 1/2 to 1 car length behind him until 75mph (about when i shift to 4th) and then he'd start walking away from me.

according to his scanner he is getting some KR down low but it goes away when RPM goes higher. he's tried different cam timing but so far the only thing that works is lower boost or higher octane fuel. with 100 octane fuel in the tank the car REALLY wakes up. in this race he was just using 91 octane like myself.

pretty good race; turned out about how i expected. he thought my Cutlass would have no problem whooping his car but really he's the one that won IMO. if his KR problem was fixed and he could raise the boost to 14psi his car would absolutely kill mine. hell, considering how well that Lotus head flows he could probably just run the turbo all out with no boost controller at all (it would probably just spike to 20psi and fall off to 13psi or so as RPM went up).  i think my car would need a 3400 and a good sized T3/T04E hybrid to keep up with him sooner than later.  although, a guy on the turbododge.com forum seems really interested in buying my Turbo Cutlass so it might be gone soon.

he's also swapping a low mile clean DOCH TIII R/T engine and a newly rebuilt OBX equpt A568 trans into his Shelby Lancer.  that one should be REALLY interesting....i think he's shooting for 500whp eventually and i have no doubts he can do it.  anyone remember the 501whp dyno vid of that white Spirit R/T that damn near jumped off the dyno when it spooled?  that was with stock cams, no porting done to intake/exhaust manifolds or cylinder head, big turbo + high boost, FMIC, methanal injection IIRC all done on a stock TIII engine.  they have factory forged crank, rods and pistons and have some potential to say the least.  if i ever get another TD it will definately be DOHC (Turbo-III) powered!

Nice. :icon_mrgreen: I'm assuming your brother is planning on upgrading his turbocharger in the near future with all that other work done?

oh yeah, bigger turbo and FMIC.  the Shelby Lancer will likely be the monster of the two.  the Spirit will probably keep the stock turbo and intercooler.

I like the fuel rail he has on that where did he get it. I would prefer the regulator at cylinder 4 then cylinder 1.

that's actually not on there anymore.  it was from FWDP.   they tapped the fuel inlet too deep so it wouldn't seal, and he's now waiting for a replacement.

fwiw he did have the +20 injectors in there (with no AFPR) when we raced, which probably hurt him a little considering he's only running 10psi (too rich).

Nce R/T.  What year is that dodge omni/horizon?  Going to do a GLH clone to it?

he also owns '87 Shelby Lancer #127, and an '86 Dodge Omni GLH Turbo.  his GLH is the fastest of them right now.

i used to own a rare factory Turbo-II/A555 5-speed '89 Lebaron GTS, but just sold it a couple months ago.

GLH's are awesome.  My cousin has a 1978 Dodge Omni with the 1.6Liter~4speed manual trans, he's looking to do a GLH clone to it.  Black with the multi color decals on the side.  He also owns a Spirit r/t but it is the burgundy color.    :icon_cool:

I really do like the fuel rail maybe I'll have to pick one up for when I borrow the +20's and 15 psi FWD computer out of my other Iroc R/T I've been working on. I guess we will be doing something similar to you guys. We should be firing up Jimmys TGP in my garage tommorow for the first time after the 5sp swap. And after he gets use to it I guess well have to go down the road together so he can memorize my license plate  ;). I also think I have him sold on doing a T3 swap into the TGP in the future. I agree with you a little lag on the TGP would be nice plus with 90 plus degree days here from april until october it should get a cooler charge even at say 13-15 psi.

you can see a bunch of pics of the fuel rail here:

his Omni is a little Monster.  it has a 2.5 common block from an '89 Caravan, cylinder head on up from a TII '89 Maserati TC we found in the j/y (stock TII Garrett T3 turbo), '89 SMEC conversion using the wiring harness from the Caravan, A525 5-speed with 3.05 FDR from an ''84 Charger, BIG NPR intercooler with mandrel bent charge pipes, ATP RS modular BOV, 3" swingvalve from TurbosUnleashed & full 3" mandrel bent exhaust Ultraflo muffler, billett fuel rail, +20 injetors,, Accufab AFPR, Walbro fuel pump, and alot of suspension brake work - Eibach lowering springs, KYB shocks/struts, welded (reinforced) subframe from a Caravan, 11" vented discs front & rear from a Lebaron GTC - talk about overkill in a light Omni).  with 20psi it was running right with lightly modded LS1 F-bodies.  he's probably going to be doing an engine swap soon since the 2.5 has ~250,000 miles at least and has alot of blowby.  he has the Turbo II engine from Shelby Lancer #371 (RIP) ready to go in but i think he might go to 2.2L crank and stay common block.  he also has an freshly rebuilt A525/A555 hybrid trans read to go in, i think he had the moly plate and OBX LSD installed in that one too.  right now it's his daily driver and he uses it to delviver pizza.  makes his job pretty fun heh.

his Shelby Lancer on the other hand is sitting dead in the parking lot.  he has almost everything needed for the DOHC TIII swap including a newly rebuilt A568 with OBX.  he has so many TIII parts in the apartment right now it's crazy.  you should see his garage.  THAT is crazy.  TD parts EVERYWHERE, full interiors, extra engines and transmissions, extra Omnni GLH gfx, extra Shelby Lancer gfx, extra wheels/tires, tons of other stuff.  he is truely a Turbo Dodge nut.

i'll try to keep up with him but i really think i'll need a 3400, T3/T04E (or a GT30R!), FMIC, and good tuning done.  i might even have to resort to 15+ psi boost with an AFPR/FMU to handle extra fuel above 2-bar.
