Quality issues? (They allways seem to crop up)
How about an American turbo? A name a person that knows nothing can trust.
Cheapest centrif. charger? IDK.
I have a huge HUGE issue with running a "Cheap E-bay turbo" and/or used." It's just not gonna happen. How do I know that turbo is good? OK, brand new outta the box doesn't guarentte anything, however, it would be a gamble I'd go with.
Doing things yourself, making things yourself is a great feeling and a wonderful thing to pound your chest on with pride, NO DOUBT! However, I'm also going by the stand point of a person unable to do much of that if any at all.
If you do not own a welder, or it's something you just can not do...... Then paying a welder is in your future. And theres nothing wrong with that. It's just money, LOL! Not that I'm saying you have to weld all the turbo pipes ... Do you have to? I don't think so.
Do you need a intercooler?
