Planning for a Turbo

[LordNor]

Hey Guys...

Some of you might have seen one of the HP turbos for sale on e-bay. I went ahead and bid on it and got it. Now I'm trying to decide what exactly I need to do to get my car ready for it. (It should be delivered next week.)

So far this is what I have:

New Custom Exhaust: 2.5" Highflow cat, inline resonator, Dual out muffler and some nice tips.
There's a shop in town that does some pretty good mandrel bends and did some work for one of my friends and he really likes them. I'm not exactly sure what to get for a cat, resonator, or muffler yet. I want something that will be louder than stock, a little deeper, and pretty free flowing. I'm also trying to keep the internal noise down a little.

Computer Reprogram: I contacted the guys at DHP and they suggested I get the Powrtuner package. I am a little worried about this as I don't really know what I'm doing when it comes to tuning a car. I really like the idea of being able to do this myself, but at the same time, I realize a professional should really do something like this.

Those are the 2 main things I can think of that will NEED to be done in order to have things in a working condition. I realize I'll be able to get more power out of it if I do things like port and polish, but right now that's not something I'm interesed in. The next thing I'm going to worry about (after this is done) is the transmission. It is, in my mind, the next weakest link.

Please feel free to leave any comments and suggestions.

Thanks!

Well what does the package come with? Does it come with new headers? You might one to look into a set of those if it doesnt. As the stock one can be restricting.

hey Blackrider, do you think he should look into a transmission?

[LordNor]

The kit comes with headers, turbo, intercooler, piping, blowoff valve, waste gate, and battery relocation kit. Included in the ebay auction was also new injectors and a boost gauge.

I know there have been plenty of posts about exhausts, but does what I have sound like a good plan?


(And I'm working on the transmission thing...) :)
The thing I'm most worried about right now is the PCM.

Its a turbo kit. It wouldent make much sence to sell a kit without the manifolds.

Yes yes i do:P

I'm not sure how far away Findley is from Youngstown. But maybe we can meet up and I can help out. Also check around for some chassis dynos and see what they charge to rent by the hour.

[LordNor]

Yahoo maps says Youngstown is about a 3.5 hour drive. I'm pretty sure it could be done a lot better than taking the turnpike as they suggesed. I'm really starting to look for options though. A friend of mine was telling me about somewhere around here that has a dyno. I'll have to talk to him a bit more.

[Lost My Keys]

I'd get 3" piping back from the downpipe... the turbo is all the """"""backpressure""""""" you need

[LordNor]

Doesn't it get to a point where there are dimishing returns? The turbo is only going to let so much through at a time. Or am I wrong here?

[Lost My Keys]

boost guage... a tranny coller could help and maybe even this

The package I got includes a boost gauge. I'm thinking I might get a different one though. The one that is with it looks really nice, but I'd like to try and keep a black and read theme going on.

I've really considered getting the regualtor. I think it would really help with everything else.


Schweppe23:

PM me the details...

Ok after some serious thought I need to make another decision and I wanted to get some of your feedback before I decide.


Would it be better to get P&P stuff from someone like RSM or would it be better to have a local shop do it?

The thing I like about RSM is you can get it loaded but I'm not sure if the place I have in mind will have the parts I need.

Any suggestions?


Also, I got larger injectors with the kit (42#) so I'm pretty sure I'll need to get the Caspers FPR with it. Is that the best model to get?

Thanks!

Any suggestions? Your going to pay more. And i have seen the Crap work first hand that RSM does. But some others have had said they did good work on their stuff. I would honestly price it out and see what going to a local shop will run you.

i would go with 3inch exhuast.

[TA^Guy]

A restrictive exhaust is a Turbo's enemy. The easier and faster the exhaust exits the better. I would run either no cat, with 3" pipes and a nice preformance muffler or a decent preformance exhaust with an exhaust cutout.

Check in the Off Topic section for the One Hot GrandPrix thread and check out his numbers from his turbo car. Using an exhaust cutout he gained between 48-51 more horsepower over a preformance exhaust by using the cutout.

My GN had no cat, an a single ATR Pittbull 3" exhaust and it pull rather nicely. :D

[LordNor]

Thanks for the suggestion but I think I'm going to stick with 2.5" I'm going to put a high flow cat and resonator back on just to make sure it isn't too loud on the inside. I don't think I should be hurt too much by doing that.

Might want to think of a exhaust cutou tthen for when you want to get serious.

BTW, my GN wasn't loud at all, the turbo it's self dampens alot of the exhaust noise.

Trying to figure out where on Ebay you found this turbo kit?:D
Would like to buy 1 for my self.

I got lucky and got it off someone that had to sell it, not a company. I got a great deal on it.


http://www.digitalhorsepowerinc.com/PowrTuner.htm

I've already looked into it and that's what I'm going to get. I've looked different places, but it seems like the only place to get it from is DHP.

Thanks, I'll keep that in mind!

[LordNor]

For the exhaust, here is my current plan...

Muffler: Magnaflow 14218
http://www.magnaflow.com/02product/shopexd.asp?zone=main&id=629
Cat: Magnaflow 94306
http://www.car-sound.com/catalog/universal/mirror.aspx
Resonator: Magnaflow 14416
http://www.magnaflow.com/02product/mufflers/univ_ss_round.asp

These will be paired with a 2.5" custom mandrel bent install.

Let me know what you think.

[TA^Guy]

I would skip the resonator IMO. Waste of time, money and weight.
Put the cash towards something like this..

[LordNor]

The resonator is the part I'm really thinking about. I'm really torn. I've seen a lot of people say remove it, but at the same time others said they removed it and it made their car a lot louder in the cabin. That's not something I want. I've also heard that having a turbo on a car tends to quiet it down a little. If that's the case, I can see the resonator not being needed.

I think the cutout would be pretty sweet to have though. Has anyone had a problem with the valve sticking?

[TA^Guy]

Actually in the past people have had problems with operation but this was years ago and QTP claims it's no longer an problem. I have seen these used on everything from Grand Nationals, Corvettes, to near stock imports and only a few have had problems.

And yes a turbo will dampen the sound of the exhaust.
