i want to know if anyone has ever slapped a turbo on a blazer. i have an 89 blazer and would really like to put a turbo on it. i have seen twin turbo kits for sbc but i want to do i single turbo. on ebay they have a single manifold but no kits. i just think it would be cool to have a fullsize typhoon. please someone get back to me.
 
I don't know about turbos on a blazer but i've seen a fair share of chevy and ford trucks with blowers on them that would give a good kick in the ass. I would think that for most applications you wouldn't even hit revs that would spool it sufficiently to produce any amount of power worth the $$$ and time it would take to set it up.
 
a turbo k-5 would be sweet. I sure there are single turbo kits out there for a small block chevy. If not its not to hard to gather all the parts that you need, and this way you can tailor it more to your application. Turbos are a lot better than a blower because they have less patristic drain on the engine and are more efficient. First off what are you going to be running as far as fuel system carb or injection?
 
Turbo's are cool but you better have a beef bottom end if you are gonna through some heavy boost at your motor. There is alot more planning involved to make everything work right then just slapping a kit on it. Especially since TBI doesn't flow air all that well and may not be the best choise for forced induction.

well i was goin to build a whole new engine and put muti port kit on it. i know i need to build a strong bottom end to make a lot of boost. i dont want to make like 800 horsepower just like 350-400 would be fine i just want to have some cool. do u think i would need to put low comprestion piston in.
 
I was watching trucks today, and they slapped a turbo onto an older Ford lightning..
If putting a turbo on our trucks is as complicated as they did it, my god, gimme a supercharger and I'll take the slight power syphon from the engine to run it..
What he did was put the turbo on around the drivers side, under the bed, right before the tire. The compressed air was then re routed ALL THE WAY BACK to the engine bay and to the engine intake...
Maybe on a street truck, it's worth it. But if you;re rock crawling/ trail riding... yeah... no thanks.

I know a guy that put a system like that on a fourth gen camaro - the turbo itself is back by the rear axle.. yeesh, like those cars need to have even less ground clearance..
 
There is a company in Utah that makes single turbo kits for newer Subs, Tahoe, Yukon ECT.
No reason you could not adapt one to an older K5. If not they have a univerasal kit.
Very reasonable prices too.

besides the kit. You will need a FMU, or Boost referenced fuel pressure regulator, bigger injectors, intercooler, and some kind of ECM you can custom tune.

Turbo

I would not think that Turbo would be the way to go. Turbocharging makes most efficient use at high RPM. For low RPM boost I would think that a supercharger would be more efficient. How often will you use sustained higher RPM wheelin?

this is not always true, it all depends on the type and size of the turbo. Look at a cummins they redline at 3500 ish and they have aplenty of low end torque and don't rev that high

Yeah, but you can't really compare diesel turbo to gas turbo. I was just looking into this a few days ago and came across this article that spelled it out pretty well.

i brought up that point to show that turbos can be desgined to fit a specific application, yes there are turbos out the that will spool fast at low RPM's for a gas engine, but you will loose top end, it is all a game of give or take unless you can afford a varible geotrmy turbo then you get the best of both worlds
 
With todays high gas prices. I would rather have a turbo than a SC. Running a blower all the time takes fuel and robs MPG. A centrifical blower does not really make its full boost till around 3K rpms wich is the same as a turbo. A roots type blower starts making boost lower but then you are enriching the AF ratio at a lower RPM.
Altho I like blowers. I can see why most all auto manufactures have given up on them and gone to turbos.
Turbos work better in day to day driving. Without robbing power and gas MPG till you need it.
Are they good for trail rig? No probabally not. But in reality neither is a blower. Unless you like to spend a lot of time over 3K RPM.
But for a street /trail truck. A turbo would be a lot of fun.

That article reads like they don't know jack about diesels to me....:rolleyes:

"30,000 or 40,000 RPM (where diesels operate)" - pffft
100,000 RPM on the turbo is not uncommon on todays diesels...

"The boost is typically very low: in the 5-8 psi range." - whatever
My previous Dodge Cummins would boost into the 40psi range and was very streetable... (stock boost was 20psi)

Really the only main difference is a little bit in the exhaust temp and volume levels. Another difference is with a throttle body you should have a blow off valve, diesel engines do not need a blow off valve.

With the proper sized and wategated turbo built for your engine and target horsepower levels would be a great addition to any motor no matter what the application. IMHO
 
Yeah I noticed the "tens of thousands" of RPMs...obvious typo. In general they do a good job of identifying the differences in the turbo application, regardless of the numbers themselves. 40 psi on a stock Cummins sounds awfully optimistic but street vehicles aside, older caterpillars (dozers, excavators, etc.) and such do run low but very steady boost pressure. I think that is what the article was getting at.

A decent 383 will give you that easily...with no turbo or blower
 
How about a turbo 305?

Might actually get some fuel efficiency out of one if it had the "on-demand" power of a turbo pushing it.

There must be some reason you don't see much in the way of turbo 305's. (short of the fact that very few care about the 305 in the first place lol) Not sure why though, it would seem an interesting project just to do, unless there is some inherent reason why the 305 can't be turbo'd.
 
Several years ago I "modified" a a 1966 Turbo Thunderbird 4 cylinder. With the factory boost it was 175HP with 6 pounds boost. After modifing a few things it put out 328HP at 15pounds of boost. It would easily out run all the local Mustangs and Carmeros. It also got 28 mpg with normal driving.
Sorry to digress, a turbo will make about 50% more HP than natural asperated. A few things I learned allong the way is Rebuild the engine with forged DISHED pistons, "o" ring the cylinders for greater combustion control, use a very mild cam ( possibly similar to a "RV" type ) , have Ford valve stem seals installed by the machine shop for supperior oil control, and have a good 3 angle valve job. A port fuel injection manifold , and a variable vane turbo. It would probably be better (and cheeper) if the turbo,injection system, and computer came as a package and mached to the application.
If you could put wings on it, it would fly!
