i'm the guy who bought all of johnisenglish's setup.
i'll have a ported motor with rew housings and i really dont want to put on the stock twins. i've talked to sean at a-spec and am planning on putting the gt42R on the car.... eventually. i dont exactly have the extra $$$$ sitting around to get it just yet. and please dont give the the speach about money, i have plenty alloted to the cause, but my plan was to get it running with the stock twins first and go from there. but...
i can get a T66 for a steal, and i'm thinking that it might be better to put on at first instead of the non-seq stock twins. i know its on the smaller side for a 20b. i've done a search to see if anyone has used the T66 on a 20b before, a gentleman damed dick (lambert?) and Evilaviator uses it. and i found a few threads that talk about them:

so my question is...how well will this turbo work on a 3 rotor? still researching, but i thought i'd ask and get a general idea of what others thought. i imagine it will top out pretty quick (.96a/r), especially on a nicely ported motor.
goals for the car:
i'm not going for the stars here, 500+ rwhp, with a very quick spool, i dont want to run more than 1bar.
mainly a street car, maybe a trip down the strip to see what she'll do.
i live ~4200ft elevation, and do a lot of canyon driving. so a roadrace type setup is what i'm thinking of going for.
so any thought, opinions, criticism, would be appreciated.
thanks!

 

ok, i didn't push the submit button and just researched for about two hours between writing this and actually posting.
damn i love the search button!!!!

anyway, i learned alot in the last hour, so i'll wait to hear some opinions before i make a decision.
thanks guys, the 20b crowd is cool

 

I wouldn't waste the money getting a temporary turbo. Just run the stock ones in non-seq form and you'll be at or near your 500hp mark.

 

Autotech Motorsports in San Diego had one on their 3rd gen conversion. Whereas I think they have the best technique for doing the 20b swap by a long shot, the engine was down on power from it's real potential due to the T66. This is what they told me a few years ago at Sevenstock btw.
They had a large street port and 3mm 2-peice ceramic seals.
Here is their dyno sheet:

I'm no dyno sheet expert, but it looks as if it might be choking out at 4500 rpm and up.
