I admit it now at the very start of this post: I KNOW NOTHING ABOUT TURBOCHARGER SPECIFICS. I understand the concept of how they make power, and I understand that they also take power to make power. I consider myself somewhat familiar w/forced induction, as I've worked a good bit w/it in the past. (granted it was an eaton m90 system on a v6 ford engine)

Now to to question I have. The other day CLICKETY was posted in one of the sections (forgive me I've slept and played w/my kids since then) and the OP was told this system was better off forgotten about. Why is that? What about it makes it a bad kit? Anyone feel like taking the time to explain it to me? I'm not looking for "BECAUSE IT SUCKS".. if it sucks so bad, what I want to know is WHY it sucks. What would need to be changed to make it worthwhile for the money?

 

For one, not much specs on the turbo headers... thickness, etc... It looks like a fine kit sitting there, but where are the pics of it on a car and working & lasting ???

I would go with BBS Headers, many people here have them and working & I haven't seen 1 bad review...

Anyone else care to chime in???

Hey man - I've been a part of the IS300 tuner scene for a little bit now, and while I know nothing about BB's I DO know a little bit about forced induction. When it comes to the IS300 and many other important tuners, the rule of thumb is to STAY THE **** AWAY FROM EBAY KITS (excuse my french but I wanna make sure you get the point) and let me explain why. They brake. They produce very little gain. They do no fit together properly. The simply don't come complete in the mail. They do not work. Any of these or combinations of these problems can and probably will happen with these kits. A proven, reliable turbo kit that puts out respectable numbers costs a minimum of five thousand dollars in the IS300 world. The cost can go up well over $10k. I can't imagine there is an 80% price drop between that and third gen camaro turbo kits.

 

Ok so far we have questionable headers, and ill fitment. (along with poor output) I was always under the impression that with most turbo kits, the piping and a quality intercooler was the most expensive part of the kits. Am I wrong in this? I know a quality turbo is important as well as the fuel delivery system upgrades as well. Any other folks want to chime in on the posted kit?

 

doc_g
#1 those headers will nto fit a 3rdgen fbody, they literally put the turbos threw the hood

#2 the turbos included are fine and can support anywere from 800-900 crank hp

#3 the oil feed and return lines are junk they will crack and leak on u

#4 nothing wrong with the intercooler or piping kit

#5 oilcoolr i have no experiance with so i wont give any advice on it

#6 the wastegates are fine(though the springs dont always give u the rated presure the springs may be 7psi +/- 10%

#7 the couplers and clamps in that particular kit are fine

so if u total it up and buy everythign seperatly u can prolly peice it together a lil bit sheaper

 

yeah so this is the type of post I was looking for. Break down component by component. Thank you sir. I wont be investing in a turbo kit for a bit, but when I do, you've given me a good starting point to look into.

 

not sure if u are aware but all of that stuff is made in china or various other countrys. none of it is brand name stuff. but the stuff does work.

i wont say this stuff hasnt blown up on ppl either but for every story of this stuff breaking i can link u to a story of somone putting down good numbers,or ppl using this stuff for many years.

it maynot be the best stuff but it will get u started and get u boosted pretty cheap to were u can upgrade down the road

 

Which is what I am looking to do in the future. I figure once I get the damn thing off the road and in the garage (where it will see some considerable time since my budget is tight, and my blood, sweat, and tears are free) At some point if there happens to be a budget for 5K-10K turbo setup we'll see what happens. My plans for this car are modest at best, I want it to handle and still be a capable cruiser w/the occasional blast down the track. I'm more concerned with a good looking clean inside and out well put together car. After I get one purchase paid off (that unfortunately got put on a back burner) I guess I'll have to start looking into a HSR intake.

 

here ya go - this thread explains it all

Man, I would never put a remotely questionable turbo kit in my car.....never.

 

I would sooner build my own. You'll learn a lot (it really isn't complicated) and be very happy.

 

Thanks but that really doesn't help me much. I was looking for someone who was knowlegable in turbos to pick the above kit apart letting me know what would need to be replaced to make it usable but still budget oriented. Project did that rather nicely and I thank him.

which is why I asked someone knowlegable to pick apart the above listed kit.

That isn't totally out of the question, but I as I know nothing about turbo specifics I don't really know what I'm looking for. The above kit will need the exhaust manifolds changed, and a larger intercooler. I may possibly contact the owner of the kit to see if I can get the rest (sans intercooler/headers) of the kit for a lower price and change what needs to be changed. Either way I think I've found what I wanted to know. Again Thanks project89.

 

I went the procharger route, but if I wanted a turbo in my future, I'd pick up a header set from BBS Designes now... everything else is easily obtainable... he even ceramic coats his headers too... Unless you have welding skills, the header is the hardest part for our cars due to room / space requirements...

Project89 gave you some good points about that kit.
Unless you must have a twin setup........I would ebay search "chevy turbo header" and look for the single turbo setup. It looks like a knock off of the BBS header for about $250 shipped. Of course the pipe quality is less for the cheaper price. BBS is a quality product from the pics and specs I have seen/read. It is the same material as the twin setup you posted. You will see them listed from time to time.

Add a 60mm or 70mm china turbo ($350) and oil lines (steel and stainless steel braid) from a turbo shop (non-china) for $80. Then get a china wastegate $60, a china IC $100 and pipes $100.

That is a cheaper kit and will fit in the engine bay and still be capable of 700 BHP.

 

junk i got a supllier of the 69mm china turbo with a .63 p-trim turbine
going for 329$'s shiped off ebay

so no reason to settle for the 60mm units anymore

the guy dosent list them often but he always has them instock usually u just shoot him a mail on ebay and hell put on up for ya

 

Am I reading that right? A T4 flange turbine with a p-trim wheel (64.5mm exducer, 74mm inducer) with a .63 A/R? That A/R seems small for that size wheel. I can't find a turbine map to match that size wheel and A/R to determine exhaust flow (backpressure, spool RPM, etc).

Since it is a P-trim then it is a "big shaft" exhaust wheel, right? Is that turbine a knock off of a Master Power turbo?

 

should be a big shaft,unfortunalty i dont have that turbo in my hands, but u can get it with .63 or .84 housings.

knowing these guys im willing to bet the actual housing sizes are .9x and 68

the guys measures the wheels but im not sure on if he dbl checks the housings

lemme dig up some pics for ya

 

I agree. A .96, .84, or .68 would make more sense for a wheel that size. The A/R is kind of difficult to measure, but can be done somewhat accurately to get you in the ball park.

The .84 and .96 would make it somewhat like the GT4088R in terms of turbine flow. The China unit flow would be a little less. This unit would spool a lot faster than the Ford diesel turbo the other thread was talking about.
