i'm running the 10.5 protorque lockup 28-3200 in the 87 and like it alot (paid about 800 for it new 5 years ago).
spools great (maybe too fast
) and room to go bigger on the turbo later
i had an unopened 87 motor with a 3" downpipe , testpipe , duttneck , stock turbo , 50# injectors ,mickey radials tt chip and alky on 93 pump gas
you need the trans to be up to the abuse as well as the rear and i had that taken care of
hits hard off line best of 1.57 leaving at about 3psi (did i say it spools fast on a stock turbo) , 12.003 110. 24psi
you say not concerned about strip
it drives great on the street, its not like stock (i can rember driving the day it replaced my stock D5 12" (not restalled) , you know its not stock but its not bad either . rolling spoolup to max boost (for me thats low-mid 20s) is instant (more so than from a dead stop) , i can light the tires at will so be sure you have a good set of street tires , having lockup gives you back the same low rpm highway cruising you have now which i use a lot going cross states for our club meets , and with a turbo step up to a ta49 /te44 with the 82 a/r exhaust housing spoolup is still instant,
you mentioned a bigger turbo in the future i tried a 6156 and the 2800 was little too low for that , some would be ok with it but im spoiled , at the track the 2800 isnbt a problem because you can build at the line but the street is different and lag makes you first looser , but lag it is good for traction control
with that turbo you want the 9.5 3200 lockup would have been a great matchup on the street or the strip
btw whos this Jhuber (aka JH ) guy LOL
