well I blew my turbo gasket on my 88 10th a.e.and I have desided to upgrade at the same time.I just can't deside on what turbo to go with.1st I found a 89-91 with only 20,000 on it.I also found both new a turbonetics t04b and a new turbonetics t/3-t/4.Let me know what you think.I got to get my car back on the road a.s.a.p.

 

Well piping issues aside I'd say the one that spools the quickest and delivers the most volume without having to crank up the PSI.

 

an 89-91 isnt a huge amount better than the s4. the biggest difference is the wastegate (which is a lot better). out of all those i would take the to4b. but you'd need an external wastegate and custom downpipe and stuff.

 

Have a look here, does a great job with hybrids:
