8valvegrowl I can do staged tunes right now, not full-on custom tunes.

I think you'd be surprised how much power a T25 Stg 2 or 3 tune puts out.

christian900se Yep, Chad upgraded a T25 he wanted gone so I got a good deal on it. Its a true 'Big' T28 because the internals were bored out to accept the full t28 wheels. I dont think he does them anymore since the machining process is labor intensive and not worth the extra money but I lucked out on one.

I dont think there are too many T28 turbos off of other cars, but Garrett GT28 turbos fit.

So did you go with a T25 upgaded to a T28 from Chadwick or a pure T28?

If the latter, are any cars fitted with T28 stock that fit in the Saab?

agoodrich pm sent.
yeah the ecu wouldnt be a problem. IIRC 8valvegrowl could give me a custom tune.

Tweek's Turbos I have ran around for years on an upgraded T28 done by Limit Engineering in AZ with no upgraded injectors or ECU. Back then it was around $500.

Ask Chadwick to do it up for you.

Once EPL gets a wideband we are gonna turn it up really good.

sleet hey man i have a t25/28 and 50lb injectors i been meaning to put up for sale. also have it still mated to the exhuast manifold. works great. pm me if your interested

agoodrich would i be better off just getting a td04? i mean the oil lines need to be changed but would it cost less and still allow me to greatly improve power?
06-05-2009 09:04 PM
agoodrich where did you get your injectors? the only ones ive found are the bosch on elkparts.

8valvegrowl can do a custom tune i believe so thats the part im least worried about.

i just want more powahhh. im not as thrilled with what i have anymore.

agoodrich 500 just for the turbo or for everything? cuz if thats for everything that seems cheap. what injectors did you run? and wouldnt i just be able to program my ecu?
06-05-2009 08:36 PM
christian900se If its a proper t28, it will bolt right up with no modifications. The only thing is if you go with a bigger turbo, you need to get a new ECU and bigger injectors.
That said, I have a 'big' T28 which is working out great for me, expect to pay around $500. PM Chadwick on here, he does them.

t25 to t28 upgrade

well i have recently had a seal go in my turbo. im going to replace it. but i am interested in doing the compressor upgrade to the t28. im wondering roughly how much it would cost and what i would have to do to remount it into my car. any difference in inlet and outlet sizes?
