Little advice - SRT Forums

Tommy the SRT · 01-25-2008, 06:31 PM

So after doing lots of thinking and reading about tunning and ish in made up my mind. During summer i was planning on doin some upgrading

First off I was thinken about the ss turbo from ptp. Bolts to stock manifold so i thought that was nice.
Was also gonna get fuel pump rewire, fpr mod also.

To tune for fuel and boot i was thinking the
Turbo XS DTEC Fuel Computer + Boost Controller Pro

Will i still need a map clamp if i get the dtec or no.

Also to monitor my a/f doesnt that dtec include a way to reat that. Or will i need to get a wideband.

Let ya know i already got stg 1 injectors on my 03.

You won't need the map clamp with a Dtec. And you will still need a wideband. From what I understand, you'll need bigger injectors and possibly a manifold before you really see any big gains out of it, for the power is made by upping the boost with these.... I'm sure someone will correct me on something...

Also, Zane might have you post this up in PTP's section since this thread deals with a build around an SST. John's the expert on these and everyone else's input is pretty much null / void....

Tommy the SRT · 01-25-2008, 07:40 PM

ok so i guess ill be needing bigger injectors, 750cc right?. Ok that helps knowing i wont need the map clamp, and that ill have to get a wideband.

Aftermarket manifold ehh. Would that be if was wanting to run alot of boost with it. I was thinking only 18 or 19 pounds. Yes everyone else chime in

I think 650cc work great for the set up you are looking at. Also save you I think almost $100 maybe it was $50. Search Deatsch Werks not sure if PTP sells them.

750cc I think is left for BIG turbo guys. like the 50's.

I dont know why you would need new manifold for SST but you may want to have one that has been worked over to flow better.

I dont use Dtec so hopefully a few that do can chime in with Dtec experience.

The dtec has a wideband tuner that works well with it for datalogging. It is expensive though. Bought locally, you're looking at around 400.00. Online, usually around 359-379 plus shipping. If you get the dtec fc/bc, this is the only way you can datalog your afr. With the dtec fc, you can get a Uego or LC-1/LM-1 and an analog/digital pickup and datalog the afr through the dtec.

If you're not really interested in being able to tune on your own. Meaning throw it on the dyno and get it dialed in then leave it alone, you can always get an Safc, manual boost controller and an Aem Uego and leave it at that.

if you want to run over 18 pounds you should look into a ported exh mani to help lengthen the turbo life. 650cc injectors should be plenty for the turbo also.

why would you spend money on a turbo only to throw it on the stock manifold? Have you seen what the stock mani looks like off the car? It is a giant POS with a LOT of room for improvement.
If I was wanting decent power for decent cash with room for big improvements, I would look into picking up just a S3 turbo. Maybe steel wheel to save a good amount of cash. Later down the road have that turbo worked over and have an external wastegate added.

Just my .02.

That is what I would say to do as well if the person had an extra $1500 to $2000 laying around for the manifold and turbo. I don't think he does... sooo.

The SST works very well with the economy manifold. You will need 650 injectors and a rewire for the pump (255 pump should be added to this but not 100% necessary). Now with that said, we have a SST car running one of the PTP manifold with a pump, rewire and 650's. It only has a map clamp on it but it holds 11.2 AFR's all the way to redline with no issues. Will you need the AF tuning device? Maybe, but it is not necessary. You will see 300 + and up to 340 WHP with this set up on pump gas (several have done this now). On race gas 350 and up is very easy to do but your getting near you limits for fuel delivery from the stock system. With that said, get the manifold with the SST since its very much worth it.

I would save up and get a Fiddy or fully modded stage 3. Cause you'll just want to do it over once you get all of that stuff. Low to mid 300's is just not fast enough after you get use to it for awhile. You're gonna want more.

kingj07 · 01-31-2008, 12:08 AM

im in the neighborhoodish of 300 and i would probably want more just as bad as if i was in the neighborhoodish of 400.

moltenice · 01-31-2008, 12:12 AM

The 300 neighborhood is alot more hoodrich then the 400... and so it continues on up..

At 400WHP with the SRT's weight, you are a heavy hitter on the street. 500whp and that much meaner...

For 300, you are in the kill zone for a LOT of cars...

Just depends on how classy ya wants to be.......

kingj07 · 01-31-2008, 12:52 AM

lol, 300 is a heavy hitter on the way to get groceries dude. ive honestly never been spanked except once. that was because i mistook an '03 cobra for my friends v6 p.o.s.

the want for more powa will always be there. funny for a guy whose been power modless for about 3 years to say that, but its true.

moltenice · 01-31-2008, 01:02 AM

yeah, 300 is nothing to look down on... but I guess it just depends on the use and the company, I mean some areas have lots of cars that compete and that drives people to get faster, others are more relax and it's different. Seems more chill up here.

Checksum · 01-31-2008, 03:08 AM

yeah... I drove a stock srt4 for the first time the other day and was like "why would anyone buy this car?" It just felt gutless.

Then again, I remember when I first got my car and was running wastegate default which was about 280whp and that felt fast at the time.

I say if your going to go big the do it right. You can get a 60-1 with a smaller AR housing and make 50 + WHP over the 50 trim at redline and they are near the same price.
