Hey guys,
I got a problem here...
Got a 93 DX coupe
B16A bolck, GSR head...
I got a custom turbo kit, done by me and my friends at the shop, pieced together from various parts not broken from my old trubo kit...
BTW, don't buy TSI (turbo Specialties Kits)... They are CRAP...
I got one from Slowboy racing, just cause I wanted a GOOD QUALITY kit, and I got PLAYED....
The guys there sold me a T-20 turbo for my B16A... WTF????
Of course, me being naive at the time, decided it looked like the best option, well turns out the turbo was WAY WAY tooooo small. I thought it was a T-25 when I first got it, but after it died, we pulled it apart and the turbine wheel was alot smaller than a Mitsu 12A turbo. So, I still don't understand why the turbo broke, it just siezed one day... And no it's not cause of lack of oil, or anything, because it had plenty... I'm guessing it was being EXCESSIVELY overspun, with a redline of 8 grand, the turbo couldn't flow ANY air up high....
So, I put on a TD05-14B, with tons of custom fabrication, and it worked great for like 3 weeks...
Then all of a sudden while I was on highway, the tach started "jumping" all over the place, and it was making no power... This happened while it was raining, so I thought the distriubutor was gettin damp...
Well, it turns out that the dist was dry and all....
So I checked Coil, it was ok.
Checked spark plugs, swapping them with others, same problem.
Then I changed computer MAP with my buddies, who's running B16a w/ 14b...
it got a lil better, but it still occurs... and now it seems like it takes for ever for it to boost up. I mean like the timing is gettin retarded....
Could this be the Distributor itself?? I've read a "jumping" tach means a bad coil, but I just changed it last year, and it checks ok (ohms), So WTF???
anyone else have this prob??
I'm running Uberdata
450 DSM injectors
1 degree timing retard/psi boost
B7k NGK's at 0.30 gap
Any help would be appreciated...
