Im in need of some help.. Been reading some threads and was looking for some input.. Right now my 87 GN has champion ported steel heads..6o lb injectors..walbro pump.. houston downpipe with duals... turbo tweak chip from eric...was on alky now on E85. have a Precision 9.5 lockup converter with a 3200-3400 stall rebuilt at Jimmys trans in IL.- I did buy car with trans done. Paperwork says"2004R to 2004 RSS with diff clutchs for 3RD and 4TH"... with my setup with a T49 @ 23 boost.. my best 1/4 with alky was a 12.3 @ 108mph.. always seemed like my car after 1/8 lost power.. 1/8 in 7.8 @ 87 mph.. 60 foot 1.7... I was doing those times with stock heads.. then I blew a head gasket... soo I did the champion steel heads.. E85 setup and also did bowling green intercooler.. BFG drag radials-car lauched better on street tires.. always brake boosted at 4 pounds of boost with each setup-always started in 2nd gear.. soo with that TE44... I did best of 12.8 @ 108 mph with boost at 20 and 1/8 at 8.2 @ 87 mph 60 ft at 2.09... once again seems like after 1/8 I loose power.. My trap speeds with either setup always 107-109mph in 1/4.... The one time I hit 110mph was day I blew head gasket...Blew head gasket on alky not E85...
I would like to do a set up on 93 octane.. Going back to stock intercooler and street tires.. What would you recommend for a turbo? what boost? I would like to keep it safe/reliable and take to the strip here and there.. Be nice to hit 11s but low 12s be ok.. More concerned on not blowing stuff up.. Also after I did E85 I did do plugs ofcource.. I would sure appreciate any help you could give...
