i have a 97 ws6 ta with 14,400 miles i bought the car new and blew the engine up in 99. i had the engine rebuilt about 3 years ago and had the compression lowered to either run a turbo or supercharger. i have made up my mind and am going to run a turbo. but who makes the best kit? most complete? best fitting? least problems? kit shipped in a prompt manner? the only company that i know of is pro turbo kits. how are these people? and is there anybody else besides them and STS? thanks in advance

 

Sounds like you are on the right track. I would DEFINATLY go with a front mount turbo, as the STS ones are junk IMO. The front mount turbo's are the ones putting down the big numbers, and are a much more reliable efficiant system.

Whatever turbo kit you get will cost a lot though, and I have heard a lot of people waiting REDICULAS amounts of time to recieve them (some cases paid in full and waited a full YEAR to recieve them).

Past that, I'm not sure who the best is. I always wanted to go turbo, but decided to go SC myself for $ reasons.

 

there are guys making 800rwhp with STS kits........... junk? maby a little strange the way they are mounted but deffently not junk

 

Like I said, IMO, they are junk. Just from what I have seen, and MY opinion. Especially when compared to the quality of the front mounts.

 

i was planning on spending about $6000 .i just want to know what are my options? what makers are there? what maker made somebody wait a year? i am patient but not that patient.

 

PTK makes the best off-the-shelf kit. You're going to have to wait for it, but it's good quality and you have a lot of turbo options.

Stay away from the rear mount kits.

im just tired of everyone bashing the sts kits just b/c they are an odd ball design. its a good turbo, piping, wire harness.... and it makes power w/o having to rearrange your engine bay. im not being offensive or anything im just saying this isnt some punk turbonator or w/e it is kit. boost is boost regardless how you get it. well except for this one time we got 1lb of boost from a vacuum cleaner (blower side or cours) on a 94 ranger splash lol

 

I know you said you want turbo, but for $6k, you could probably have a nice intercooled SC setup that will make good boost. A T or YSi trim vortech or a Procharger equivalent. Just a suggestion.

Agreed. With that budget, you could get either a very cheep turbo setup, or a decent blower setup.

BTW, if there are a lot of people bashing the STS setups, I can imagine that it would be more reasons than its a "different" design. I don't hear any multiple complaints on any front mount setups. Not trying to start an argument here, just explaining the reasons as I and others may see it. It may not be correct, it's just our opinions.

 

That's very, very incorrect.

 

You could also check out TTi if you want. It's a very complete and good fitting kit. The problem is that it has a 2.5" log header, which isn't that bad, but the downpipe is only 2.5" also. That downpipe will limit hp output. I've never looked at it close enough to tell for sure, but I imagine you could fab up a 3" downpipe because I ran my 3" in the same place.

You defiinitely could fab up a 3" dp for the TTI kit. You will still however be limited to on-center turbine housings though. I suppose you could always build an adpater for the log manifold to reposition the turbo as well.

 

The layout of my home-made kit is extremely similar to the TTi. However, I'm using 1 3/4" primaries, a 2.5" crossover pipe, a 3" log with the primaries merging into it instead of Tee'ing in, a tangential turbine housing, and a 3" downpipe. It fits good and is actually pretty easy to work on. I basically fixed all of the TTi shortcomings. I'm even considering going up to a 3.5" downpipe.

the reason i want a turbo set up is no slipping belts. my brother has a built lt1 and a ati d1sc and a buddy has a 99 vette witha stock motor with a p1sc putting 518 to the tire. but i have 2 89 turbo ta's and 6 t type/ grand nationals so i know what a turbo is capable of. i just want a kit that fits and don't want to have to wait a year to get.i prefer the turbo in the engine compartment because that's what i know.i don't mind spending the money because i'm not gonna sell the car i bought it new and i have many others that would go before this one.i just can't afford to make a $6000 mistake

 

Yours is pretty much the same as mine (fabbed up by RealQuick). All primaries are 1.75". You're running a passenger side header whereas I'm running a 2.5" log. Crossover is 2.5". The DS log is 3" and the DP is 3" (though, a 3.5" down pipe would easily fit with my modified steering shaft). I dumped the wastegate to atmosphere under the car instead of running it through the exhaust though. I'm also running a tangential, but not quite as good of a turbo (T76 Q-trim).

Like you, I think TTI makes a good design, but fell short in just a few areas. Those areas were addressed when Jon built my parts and I think this will put down some decent numbers.

I am shocked at how easy it is to install/remove log manifolds. 20 minutes a side if the hot parts are built right. I can use a ratchet on all but 1 of the header bolts and a wrench easily fits in for that one (rear bolt of #2 primary).

The car should fire up for the first time in less than a week. Then I have to take it back apart to re-torque the head bolts and put it back together and start tuning.
