Long story short my buddy couldn't get his turbo civic running. So now he has a turbo, BOV, wastegate he said he would sell me cheap. I'm wanting to turbo the car so I thought I would pick it up. Its a 42mm trim turbo I believe he said. I was just wondering if that would be too small?

 

I am not sure what you meant by a 42mm trim. I run two 46mm inducer turbos on a mild 350ci. Together they are on the small side for a 350ci and run at about the 70% to 65% efficiency line.
I am working on a 305ci twin setup with two 40mm inducer units. Together they are on the small side for a stock 305ci but a good street setup for a little extra power.

 

speaking of turbos, is there any place i could get a turbo or supercharger for cheap for my 87 Iroc 305 TPI?

 

A few places to find used turbos are at car junkyards, truck junkyards, Ebay, classifieds, etc.

New ones from googling for Garrett, Holset, Borg Warner, Schwitzer, KKK, Master Power, etc.

Do a lot of researching before you buy used or new. There are some poor quality units out both new and used. Look into what to check for if you go the used route. Find out how much it costs to rebuild one, how much rebuild kits are, and how much hard parts are. Look into how much all the other stuff costs.....the turbo itself is only one piece of the puzzle.

 

borg warner aka ihi is the *****

 

What makes them any different than the other turbos listed? Let me guess, you own a Borg Warner unit?

 

yes i own one and i have used one on every turbo fab project i have done and been a part off (7) and never hade a problom with any of them

 

Have you ever driven a K03/K03s/K04 car?

They suck.

 

Here we go......another "my stuff is cooler than yours" thread. Why post if you have no technical data to help the guy out. Like calling out specific KKK units has anything to do whith anything here. BTW, I think it is more the cars that they put the KKK in that suck more than the turbo unit itself. Bad engineering choosing the wrong turbo. That turbo is great for the applications it was intended for.

I have driven equipment with Garretts and Holsets.....only one to croak is a 1970s Garrett 76+ mm inducer that has a million hours with infrequent oil changes. I guess that means that I should always use Garretts due to that fact.

Why cloud the poster with comments that won't really help him out and just provoke others to "give a shout out" for their favorite turbo just because. If the KKK are really that bad then post what is wrong with them mechanically. If the Borg Warners are really that good then post what makes them so good mechanically.

 

i did "never hade a problom with any of them"

 

I didn't mean to come off sounding like a d***. It was just that none of it seemed like help for a newbie. I think your post was a lot more helpful than the other.

 

Actually......The guy I quoted mentioned them being great. I was disputing his comment.

I have a 05 Jetta GLI as my daily driver. I have almost every bolton done to it and I made 203whp and 250lb-ft to the tires. For a car that spikes 24psi, and holds 19psi till 4000, thats kinda low. At 5500, power falls faster than a L98. From my experience, the K series turbos arent exactly super reliable. I have tons coming into my shop needing replacements. Probably about once a week or two.

Yes, they chose a bad turbo. They wanted a fast spoolup for people to drive around and feel like they have a VR6 and have good fuel economy. What did they choose? A turbo with a inlet that can get blocked with a quarter that has journal bearings instead of going with a slightly larger ball bearing turbo that would probably last longer and made more power with similar spoolup times.

 

Huh, maybe consider all the records set by Porsche using KKK turbos in applications that people doubted would survive at all…

 

You mean the K16 turbos? Saying the Porsche is fast just because of those is like saying the Moser 9" is great for surviving on a stock 305 TBI.

 

insn't this a 3rd gen camaro site

 

Since nobody has answered the question because they are all too busy whipping out their E-*****- I'll answer it.
NO, that turbo won't be big enough. A 42mm compressor is tiny, adn I'm sure the turbine on that small turbo (sized for a sub 2 liter motor) would prolly ahve you making full boost at idle. Oh, but the wastegate would be fine.

 

THANK YOU!

 

Funny. How do know what a "42mm trim" turbo is? I never heard of one. I asked the original poster to state if it was a 42mm inducer or 42 trim...........and of course he never did. So, you could have given him false info based on his bad info. Of course, he is happy with it though so I guess his question is answered.

 

A 42mm inducer is small. a "42 trim" doesn't exist to my knowledge...if it does...it would be tiny. My turbo on my nissan is a 60 trim... way too small for a v8.

 

Yes, a 42mm inducer would be way too small for a V8.

There are all kinds of compressor wheels out there. Who knows what type it could be. To research who made a 42 trim would take a long time for the average Joe like me. Usually, the smaller the trim the less air they flow, but who knows what size the inducer could be. So less air flow is relative.

The original poster should really post the real info. if he wants an exact answer. HHHHmmmm, got a mid-80's 300ZX do ya?

 

^
Me?
No it's a 93 240sx with a home built turbo kit. It moves pretty quick, adn it's RWD...makes for fun stoplight encounters with my V8 brothers

 

Sorry, i'm not a real big turbo freak. I'm still learning a lot. I guess I did mean inducer and not trim. Thanks for the help.

 

Sounds like a fun ride. Yeah, one of the reason I went with boost is because the 4s and 6s were blowing my doors off. Lot of good that did me, they still win because now the tires want to go up in smoke with boost.
