I ordered the Killer from Turbochargers.com a couple weeks ago. As I expected, customer service was top notch. I rec'd it last night and had it in a few hours. As arrived the turbine housing wasn't ported. I gave it a quick porting to remove the step to match my ported manifold. The install went smooth. You have to bend the water lines a bit to clear the compressor housing, but thats about it. I haven't had a chance to take it for a real ride yet, but my first impressions are very good. Spool is very quick considering the big16 wheel. Keep in mind this is on an auto. I have the boost low at 15 psi for now and i had full boost by 2,800 - 3,000 rpm. Boost is much smoother and linear compared to the T-25. Pulls strong with no creep or fall off to redline. As soon as I upgrade the injectors, fuel pump and AFC, I'll raise the boost. I'm very happy with it so far.

The T28 turbine wheel...

What an interesting matchup. What are the CFM's?

Its supposed to flow 550+ cfm.

nice..

sweet.

Im very inerested to see what times that you will run on this turbo once you have a complete setup. Keep us informed.

Very nice. Keep us informed.

I probably won't get to the track with this car. Its just my commuter with a sponge box auto. . I just ordered the Alto end clutch and shift kit for it. But I probably will leave the torque converter stock for a while. The stock TQ converter really kills the launch. 60 ft time would be 3+ sec for sure. UGH!
I really don't have time to get to the drag strip though. The closest one to be is Island Dragway, or Englishtown in NJ. Both are quite a trip. My other hobby eats all of my time and money. I roadrace motorcycles in New Hampshire. Winter is my only time to recoup from that. Unfortunatly, most the drag tracks up here are closed during the winter.

What that GSX AWD won't get down the track in the snow !

:laugh:

I gotta move to a warmer climate! I hate SNOW!

AS LONG AS YOU DONT HATE YELLOW SNOW UMMMM

Yellow snow, brown snow, white snow... I hate it all!

Anyway, I'm installing the end clutch, shift kit and 190 fuel pump this weekend. Fun fun... I can't wait to smell of gas and trans fluid all weekend.

Hopefully the shift kit will improve this crappy slushbox a bit.
On a side note, I was trying to see how low i coul'd build usable boost (hard to do on a freakin a/t). I was getting 12 psi at 2,400 rpm with only 1/4 throttle (any more it would down shift).

I have a question for the Big28 owners... When your boost spools up, does it hit hard all at once like the t-25 or is it more linear and smooth?

Mine hits hard really hard and then it smokes the tires. I love it to. At 18psi in 2nd gear if I get on it at like 2k when the turbo spools it lights the tires up.

i cleaned under my rear seat like 5 times and i didnt spill any gas and i still smelled gass for a week and i also cleaned my carpets
Makes you think you have a fuel leak for weeks and when people get in and say you have a gas leak or whats that humming noise its just my fuel pump " Its going to blow or its Broken or going to burn out" thats wat you get from these walbros. Ummm time to dino mat the car

Yeah really. My GS-T smelled like donkey ass for a week afetr the 255 install. No spillage inside either.
As for the damn noise... I must say my twin external 385 lph Pierburgs in my Stang are silent compared to the wimpy 255 in my GS-T. I was thinking of doing a pickup in the tank with one external.

Big28 guys, thanks for the responses.
The killer comes on smooth and linear more like a 20g. But real low in the rpm range.

Well thats good for ytou front wheel drive guys

yeah the Big28 spools identical to a T25.. fast and hard, just holds boost tll redline.. the problem with that on a FWD is the impact of the sudden boost means spinnage.

Makes me all the happier that I got this AGP GT25/28 now. Hard and fast hitting boost + AWD=weeeeeeeeeee!
