Am I in the right place?

[z0mbie_st0mp]

Hello, just joined your cool forum.

I have recently acquired a 1990 Dodge Shelby Daytona



And it has a 1991 2.5 L TURBO, overboosted to around 15-16 psi.



Is this where I need to be to get info for my car, or is there some other forum I need to be on?

I don't wanna mess up your community if you don't discuss these here

Thanks in advance!

Right place. Nice car, congrats.

Couldn't help but notice some of your other photobucket pics. You look like someone who puts even more effort into Halloween than my family!

Yup, it's my favorite holiday!

I do a huge "yard haunt" walk thru maze for the neighborhood kids

I like to build my own monsters and props.

Nice looking car! You are certainly in the right place. Welcome!

[Rrider]

The best place, lots of technically savvy gurus here for us TM noobs to learn from!

You have found the right place.
Now, what have you got planned for the Daytona?

Not quite sure... The PO told me that by adding a 3 bar Map sensor, some +40 injectors and an ECU chip, i could turn the boost up to about 20 pounds and it would be a real crazy street beast!

Well the biggest issue I see is the cast pistons. Unless the previous owner managed to locate a set of the factory Mahle's. All new cast pistons are hyperutectic, and will never live at elevated boost levels. If you want to run 20 psi of boost, you need forged pistons.

[tryingbe]

You need a wideband o2 sensor to monitor a/f ratio.

The stock injectors needs to go if you want to go over 15psi.

I remember seeing this on craigslist over a year ago. Guess it finally sold. If they are new 2.5 pistons, they definitely need replaced before turning up the boost. You're only option for pistons for a 2.5 at this point are forged.

Yup, this was on craigslist in 2012. Are you in the Pittsburgh, PA area or did you see the article on Jalopnik?

My aunt is the PO's neighbor. When I first bought it two weeks ago, I searched google for 1990 Dodge Daytona Shelby and the fifth result was that article. As I was reading the article, I realized that the car was looking and sounding verrrrry familiar!

I guess I own a piece of Jalopnik Internet history... LOL

I got the car, along with a Truck bed full of extra misc parts, an extra set of glass, an extra transmission and a second set of wheels for $1500

88 Daytona Shelby Z Garrett TIII T3 intercooled turbo


Heavily ported TIII exhaust manifold with EGT and external turbonetics delta gate waste gate with open dump tube

I think you have T3 and TIII mixed up. T3 is referring to a turbo frame size. TIII is referring to the 16V DOHC Lotus head engine found in Spirit and Daytona R/T's (and Phantom R/T's in Mexico).

Stock 2.25 swing valve with flapper bolted shut
2.5 inch stock down pipe to where cat was, then 3 inch straight pipe out with no muffler

If this is the actual set-up, you are going to want to change this. The 2.25" swingvalve is a pretty decent restriction, especially if you want to make power over 250whp (I've personally put down 225whp and there are others out there to claim more, but spool-up and overall performance would be better with the 2.5"). If you can source a TU 3" swingvalve, that is the way to go. Then you can do a full 3" downpipe and exhaust all the way back. If you are going to drive this any length of time on the street you might want to consider a muffler...Daytona's drone pretty bad.

87-89 stock half radiator with metal ends, stock inter cooler setup

The IC is something you REALLY need to upgrade to make good power. It is a pretty big restriction. Even a cheap e-bay Spearco knock-off is better flowing (I've tested it).

INTERIOR:
'90 5 speed high center console
Factory trip computer from 91+ car

This is physically impossible. The cubby for the trip computer does not exist on the '90 "sunken shifter" console. Unless the head unit for the stereo is remote or does not exist, this can't happen...well, not without a LOT of work because the console would have to be extensively modified.

Reaper, I just re typed what the PO had on a list he gave me...

The T3 and TIII may very well be incorrect.

The car does indeed drone... Lol, learned that on the way home with it

PO also gave me a larger front mount IC in all the parts I got with the car

As for the dash, the trip computer is currently not there, I recall the PO saying he had put it where the ashtray is, but I cannot say for certain as the ashtray is still there now

Ah...gotcha. It's cool that you got a FMIC to go with the car!

As for the trip computer: the dash itself has the spot for it to go, but the center console and the radio surround for the '90 Daytona (1-year only, and only in the Daytona) the center console is raised up and the cubby where the trip computer would go is covered where the ash tray is. The only way to install the trip computer is to get an entire center console and radio surround from a '90 LeBaron or from a '91-93 G/J body (5-speed obviously). The trip computer will go in the spot under the radio. Now, whether the connector exists on the dash harness...that's a toss up. It may be there.....it may not be there. They can be adapted in, but at that point I'd be asking whether a little box with some buttons on it is worth all the hassle. There have been people that have answered "yes" to this, so you wouldn't be alone if it is!

Welcome!
Do yourself a favor and roll through Chryslers @ Carlisle this year. It should be close to you, and it's a good place to pick up parts.

[z0mbie_st0mp]

Parts?

I got a TON of parts with it... Including a transmission and a cylinder head, extra wheels, radiators rad fan, a complete set of glass... And more... LOL

[CoolV300C]

Good deal. Surprised it didn't sell after the np or cp article.
