I have been researching turbo upgrades for my FWD DSM for months now and I'm pretty confident that I'll go with the AGP t3/t4 50 trim with either a .48 or a .63 a/r. However, I've read alot about having spool-up problems with this set-up if you don't have the proper supporting mods. I've been able to gather a few mods by using the search button, but I would REALLY like to have a full list of what is necessary to get adequate spool and to allow the car to run properly so that I'm sure not to forget anything.

So far aside from what's included in the kit, I've been able to establish that I'll need:
-3" downpipe and high-flow cat
-3" intake with 2g MAS
-FMIC
-660 cc or 720 cc injectors
-255 lph Walboro fuel pump
-Apexi S-AFC
-Apexi AVC-R
-an LSD (any help with traction will be sorely needed)

If any of you can help me out by adding to this list or making any corrections I would greatly appreciate it. I hope I'm not asking a question that's been addressed a million times, I just wanna be sure that I don't just slap on a turbo kit and either break parts left and right or have it run like complete crap because I didn't prep for its install. Thanks in advance...
 
Sorry- I probably shouldn't have said "spooling problems". What I meant in typing that is I want to be sure that I have the proper supporting mods for this turbo to spool where it should, as opposed to having a good 500-1500 rpms of unnecessary lag because I didn't buy something I should have ahead of time. I just wanted to clarify to prevent any kind of confusion.
 
Looks like you've got it pretty well figured out. You might want to get the MAF translator instead of the 2g MAF. The translator box will do a large amount of the tunning for you so your AFC settings will be closer to 0. Go with the .63 turbine housing since you are FWD and you have a 6-bolt.

Thanks for the response Kevin. When I first posted this I didn't actually expect a response from someone from AGP, but I guess your input just solidifies my decision to chose AGP over comparable retailers because of the great customer service reputation you've earned within the DSM community. My only concern with going with the .63 a/r was spool time- I really don't want alot of lag and I was afraid although a FWD might benefit from the slower spool, it might be a bit too slow for my taste. Could you just tell me what the average RPM is for spool-up with the .63 housing?

Thanks littlemilla3- I probably should have stated my current mods too, but I'm already running a Thermal 3" cat-back.
 
RU2SLOW,

How about a post from the other one at AGP. Full boost on a well supported car with cams on the .63 is right about 3900rpm. I am sure there are others on this board that actually run the kit will chime in. I am just the sorry ass that builds these things and I drive a Neon.

Also, one suggestion on the AVC-R.

If you are going to get an electronic boost controller, I'd recommend the HKS EVC EZ. I know Apexi has come a long way on their boost controllers, but in my honest opinion your money could be spent on a less expensive product.
 
Ben,
He's FWD he probably wants to use the RPM dependant boost control of the AVC-R.

RU,
The .48 will spool about 400rpm quicker than the .63 so that may be better for your needs. You are going to have major traction problems ether way.

I am sorry I am such an idiot. Buy the AVC-R.
 
I personally don't expect much time wise being FWD, so all I'm concerned about is MPH. I would get a Old Profec B if you can find one. Tried and Proven over and over. As long as you get the right spring, you will have no problems with it, or at least I havn't :)
 
Just get an AEM and forget and let it do everything. Traction control and everything.

My turbo spools faster than ever with a standalone. You can easily drop 300-400rpms just tuning a standalone.
 
Ben K- Thanks for posting as well- I greatly appreciate it. I won't have money for cams for a while after I buy the kit, so will not having them greatly affect the spool-time? I worry that without cams I'll be spooling well over 4k. Also, you say "well-supported" would you classify my above list as good enough to be placed in that category?

Violater101- I was considering a Profec B, but in reading about it I was under the impression that it only had two settings (high and low). The descriptions of the AVC-R that I've read seem to suggest that it has gear dependant boost levels- meaning that I could adjust the boost throughout all the gears if not more than just two?? In making a good amount of HP in a FWD I figured this would be a better bet for traction if what I'm understanding is correct.

Unreal- This idea about an AEM intrigues me ALOT. You say it has traction control as well? Would you happen to know if the Haltech has a similar feature? My local DSM shop has used a bunch of those on the cars they've built so it might be easier to go with the Haltech as an alternative to the AEM.

Thanks again to everyone who has contributed to this thread- this is the most dificult decision I think I've had to make in a while and it REALLY helps to have other opinions.
 
If your concerned about traction at the track, you are correct in that the avc-r can set boost dependant on your gear. I can't say how good it works because I dunno honestly. I could tell you what I've heard, but thats just heresay. If you go with the profec b, you could just get the remote switch and run low boost in 1st gear, then swith over to high in 2nd. As for the cams, I will say that they made a huge difference in my setup aswell as getting a afpr. I went with 264/272's and I can say that 4th gear feels totally different now. I havn't noticed any difference in spool time, but thats just me.
