Heey people, i've got a simple question considering turbos.

For example, My civic does 30 MPG n/a driving at 60mph (3k rpm)
What will the MPG be like on the civic with turbo? at 60mph (3k rpm)

Will it save more fuel or use more? or stay the same

kyden

if tuned properly, it could get more than before.

Records

Alright, but if your tune it properly, more leaning towards fuel economy, will that cost you extra power?

kyden

no. thats a separate portion of the map.

When tuning "economy" areas of your fuel map you arent worried about power- low RPM/high vacuum. When tuning the "power" parts of the map you arent worried about economy. Two very different sections of the fuel map, so you can get the best of both worlds.

Alright thanks mate, i assume that he map is the ecu right? or is part of the ecu? xd
If so, what would be the right ecu decision for an b18c gsr engine?

Honestly this answer depends on a million different things.

Overall, larger turbo cars can get good daily driven MPG with a good style of driving. They are less prone to entering boost and using fuel during the every day ins and outs. With a good tune, larger turbo cars can easily see higher overall MPG.

Smaller turbo cars on the other hand tend to get less MPG. Look at all of the factory turbo cars for instance. Since they create boost at such low loads and low RPMs they will end up using a lot more fuel in the end. I mean geeze you can get a WRX into boost with a 1/4 throttle acceleration. This type of setup as a whole will usually see a drop in MPG.

To answer your question directly, assuming the same small load and same RPM between a stock engine and a boosted engine, if it's low enough and the turbo isn't creating boost there will be no change in MPG depending on the tune. Tuning software actually allows you to modify each range of RPM and amount of load completely individually, and a good tuner can actually increase your low rev low load MPGs over stock with no sacrifice to power or safety at high rev high load. That's why these expensive tuning options are so important.

Alright thanks for the explanation bro, i appreciate it
Would you consider the GT28RS as a small turbo? if so, what would be the correct size in order to save fuel & not having to much lag

SovXietday

That's a good turbo, fits right in the middle. You can stay out of boost if you're careful and yet it'll still be there when you want it to.

Records

I gotta admit, when i try to find anything bout it on google.. i cant seem to find any kits or stuff, or even the turbo itself? :O

any site that offers the whole kit? or the just turbo or w/e

and are there any replacements for that turbo incase tis too expensive or cant be found;P?

SovXietday

That turbo isn't hard to find at all. Look in the marketplace here.

As for the whole kit, doubtful. Most of the time you will need to build the system yourself. It'll be better that way anyway.

Records

Ye but, i think buying a brand new one is way better.. then a used 1?
You got no guarantee it'll work & last long >.>

How long do turbos last anyway? If i buy a used one, i wouldnt want it to last longer then a couple months xD

Any specific things you got to look at when buying a second hand turbo?

Records

Bump hehe

For what? You haven't researched anything in the six months you posted last time? You should be an expert by now.

Actually it isn't really funny. To have this much time elapse and still not have a clue?

Generation X for ya haha at least I didn’t fall off the truck and I’m from that generation

Records

haha, I understand yall ;P

yet due to some not so good reasons I havent been able to do my research or even drive a car ;>

I been in jail for a lil while, so that is the reason I havent been able to get online or even do my research ;>

Bix VT

Apparently his whole life so far has elapsed without him having a clue.

Records

lets remain ontopic? :D

would anyone be able to answer my question?

Im a little confused on what exactly you are lookin for now. Are you still looking for a turbo kit? Go-Autoworks.com sells very reasonably priced turbo kits with high quality components.

Bix VT

Yes, new is generally better than used.

When buying a used turbo, the main thing to check for is shaft play.

Are you still interested in a full kit? Stay away from ebay. Do it right or do it twice. Most kits don't come with any fuel upgrades (except greddy, edelbrock etc), so you will have to do a metric crapton of READING and MATH to figure out exactly what components you need to feed enough fuel into your engine so it doesn't detonate.

When I have any turbo questions, this is my 3-step process of answering them:

Step one: https://honda-tech.com/forums/forced-induction-16/%2A%2A%2Aforced-induction-forum-faq%2A%2A%2A-1024174/

Step two: https://honda-tech.com/search.php

Step three: http://www.google.com/

So far, this process has answered every question I've had, negating the need to create a thread. Hopefully it will answer all of your questions as well.

Records

Thanks mate, i appreciate your helpful reply

And yeah I am planning on doing it reliable, no ebay shizzles, too much con's come with those ;P

But 1 question, how come I always end up at random topics, when i mtryna search for a specific thing on this forum? :O I tried searching for 2step/launch control. Yet havent found anything about either ;> Must be doing somtehing wrong
