View Full Version : what should I expect?

I was thinking of doing a turbo. Now I know it's going to expensive but I want more power. I have a few questions.

I have a 95. No SR.

1) How much boost can I run on stock internals?

2) If say I ran 10 lbs of boost, what hp could I expect to see? (I think I heard of one guy that had +95 hp added on, is this true?)

3) What kind of price would I pay? Can I do a simple buildup, like the turbo, exhaust, manifold, bov, wastegate etc.

4) Do you have to know a whole lot about them to start a turbo app.?

5) Finnaly, what would my car feel like? I've had the same power for about 1/2 a year now, and would it be so much faster? Would it be worth the money, or not?

Sorry I had to do a new thread, but I searched and found 300 topics and last time I did that it took me three days to find what I needed.

Thanks for your info and time.

Expect to pay about $3000 for a kit that you piece together yourself. And to run 10psi on a t3/4, for instance, I think that you'll be pushing the injector/rrfpr limits. You may want to look into another $600 or so worth of fuel components and management.

Each psi of intercooled boost, on average, will add about 10 horsepower. It's not exact, but it is a very good approximation. Then add on for the filter element you have, and exhaust, ect.

Two people have also run stock internals to 15psi, and 350rwhp+. Their setups look to cost about $4000 with extreme fuel management (JWT ecu, 50# injectors, fuel rail, Cobra MAF, ect.)

You'll need to know how to work on your car, and what parts you'll need to work on the turbo app.

Depending on what turbo you are running is what your car will feel like. AceInHole has said that his car feels "NA" because the power is so linear on his Mitsu turbo, whereas my t4 kicks in boost at 3600 rpm, pulls the front up, and throws you in your seat. My setup is not linear, but I have a lot of lag.
Turbo's are definatly worth it... as long as you don't blow your motor.

You can see my turbo setup at my website www.jeff240sx.freeservers.com

So does that mean fuel injectors? I really don't want to get into that! How much boost can I run safely?

Without changing fuel injectors, you will be severely limited to how much boost you can run. Once again, this is dependant on the CFM output that your turbo will produce.
This said, a rising rate fuel pressure regulator will give enough fuel for about 6psi of boost on a larger turbo, and possibly 8-9psi on a smaller turbo. You will have to replace your fuel pump with a high-output pump, seeing as increases in fuel pressure will work directly against the pump. I'd highly suggest not taking the 270cc injector / rrfpr route to boost. I would recommend at least 370cc injectors (they will drop right in from 95-96 300zx TT and all RWD sr20det motors) and possibly a Z32 maf with JWT ecu. That will get you 8-10psi safely.

Moose: From what i'm seeing you are better off buying a kit, cuz from your approach you'll mess something up rather fast. Go read some books.

i agree w/ Kreator

i think you would be mores suitable for an SR20DET then a KA-T.

u can drop a stock SR in and add some bolts ons and go zipping along w/ some good power under your foot. pay some one for install if you'd rather not worry about wiring problems/install issues.

a KA-T requires knowledge, ability to research and know how about engines and problem solving abilities. something u lack.

true, true. I have the knowledge, I just the door wide open for anyone that would like to add something. I know how turbo's work and stuff, I can't say I'm a genious, but don't think for a second that I don't know anything.

I was getting some info so I could get the pros and cons, to make my decision.

What do you mean anyone else? What the hell did I just answer your question for? I have told you the basics of what you need to know, if you need anything else, just ask.
Also, for pros and cons, I am definatly not anti-sr. If I blow another KA, I'm definatly going that route. I pretty much know the pro's and con's to the KA (since I've blown an engine and installed it myself and have helped at least 4 other people from the beginning to the end of their turbo dreams).
If you have anymore questions, just ask. But seemingly throwing off the only person that has helped you by not thanking them, and saying "anyone else" is really a bad way to do things.

"I have $500 saved up, how can I twin turbo my car and make it run 10s and drift real good? I been driving for only a year now and I think I'm getting real good so I want to step up to real horsepower. Driving a 10s car on street tires can't be that hard, right? And that drifting stuff is easy, especially when it just finished raining!"

FSM is not really needed. Jeff240sx did it without even chilton's (i think). But you have to know alot of general ****, know your way around car, and know every single part you need. Before i started putting it all together, it all looked easy to me. Only now i realize how much little stuff there is.

Jeff, I really didn't mean it that way.
I was simply asking about any other opinions on the board. Yes you were totally right about everything, and I'll use your info when I decide to do it or not, but sometimes a different perspective is nice. Don't take it the hard way. Everyone needs a second opinion Jeff. Sorry for the confusion.

Well you can read some books, or you can get the first hand info from the people who know their ****. I don't like reading some books on that stuff, because I don't want turbo in general. I want to know what some people have done to their car and what they got. Not just some words and numbers. Thanks.

Yea. I'm kinda like a big dick with ears. I'll scratch my head, and then super-engineer prowess will kick in, and a day later, I'll figure things out. I didn't read no stinking Maximum Boost or stinking FMS or Chiltons. F! that! LOL!

You'll really need to know what you're getting into. If you ask anyone that has been around, I searched through the entire archives of Zilvia (small at the time) and FreshAlloy. I must have read their "Best of 240sx" about 3 times now. Just study up... if you have any other problems with the install or parts, check out my site. I even have the basic turbo install documented.
As for a turbo to run, it depends on the boost you'll see. Most people run a t3/4. I'm running a t4. And others yet are running a t3 for power with response. If all else fails, ask.

So what you guys said about knowing your parts and how to fix it and stuff are for ppl that want to piece together thier own turbo kit? i am asking because if i ran into a problem where i would need to know a lot i wouldnt know. Would be ok for a person like me to buy the xs kit, nsport or fmax and run the recomended boost without running into too many problems or maybe even none at all?

this is kinda off the topic for this post but i really want to know

thanx

You may even want to pay someone to install the kit. It's really not that bad (in kit form), but... if you run one wrong vacuum line, you'll blow up your car. You'll also need to weld stuff. If you don't feel comfortable with that, pay for the install. Then, run at the recommended boost level. And with most (if not all) kits, you'll need to buy a separate fuel pressure regulator (not safe for plug and play) or get larger injectors and an ECU reprogram (which is what I'd highly suggest to you.)

****!! i made a long ass post and accidently hit "Back!" now i guess i gotta try and remember what i wrote. here it goes..

you sit here and say u dont wanna read books about turbo in general, yet u sit here and Wait for people to reply to your post so you can READ about turbo..i dont get u..while ur waiting and complaing.."is Jeff the only one that is gonna step up to the plate?" no..others dont wanna answer/flame becuz ur not takign any action to learn yourself!!!! Read a book while ur waiting. read a book while ur taking ur daily ****. some people learn from books, while others get first hand. in the end your both gonna end up with first hand exp. dont expect people to tell u what to do and u can do it right away..mayb u could..but are u gonna remember WHY u had/have to do it??? read books..u dont like too..i dont like too..yet i wanan learn so im reading books. take notes on what you read! or bookmark it so u can get back to it!

u dont wanna know turbo in general?? you act like turboing a honda and turboing a Nissan are two completely different affairs. turbo is turbo. the cause of a boost spike on a Nissan is and Can be the same cause on a turbo Honda. you need to read and learn what your getting yourself into. you want first hand exp and people who know their ****..guess who writes books!!! people who know their **** and had/has first hand exp for many yrs. i could of turbo'd my car long ago but i dont know much enough to turbo it. i still need to learn. my brother has learned helal **** on turbo from...

1. reading books on turbo
2. reading articles on turbo on the net
3. hanging around on turbo forums AFTER 1&2 were completed and understood...asked question if he still didnt understand

numbers and words? you need to learn the numbers and learn the words..learn to calculate hp etc etc..learn what the numbers mean on your AF graph..you cant juss sit there and say.."yeaa this line goes Up very high at 2.5krpm then drops very low..yes i understand" no it doesnt work that way.

u want to know what other people got? thats kool..but becuz u got the same mods dont expect to have the same gains..y? diff height in sea level..tuning and more tuning.

turbo is turbo. whether its on a honda or a nissan. they all have the same concept. Learn to walk Before u run.

i mean..look at Jeff, he read the "Best of 240sx" 3 times..u know how long that **** is!?

if u wanna learn about turbo...i suggest u do or try to follow what my brother is doing..its working for me...from what you said..u havent done much.

i know some guy who bolted a turbo kit on his civic Si and hez running 15 flat. u wanan be like him??? i dont think so since my brother is running 15 flat with just a intake. granted that the GSR already has 170 vs 160. but the Si has a T3/T04E i think

be smart. learn your ****, then ask when u need help.

ok , its like this and dousan put it well. If you do not know much about turbocharging and are not willing to read and learn and have mechanical engine knowledge, you are better off buying a factory turbo engine.
Now even with that there are some things you must now. Turbo engines require more attention to matinence than NA engines .If this is done they can be completely reliable. I must say this though and say it emphatically. Regardless of getting a SR or going KA Turbo you need to upgrade your fuel pump. This is one of the biggest mistake areas people make in either setup.
The stock 240 fuel pump was installed to run 270 injectors. SR's come with 370's stock. Most KAT setups recommend at least 370's to run 7 pounds of boost or more. RRFPR's are stop gap devices in my opinion i.e. setting up a engine with a RRFPR on 270 injectors is pushing your fuel system hard . I would not recommend it.

Yea. This is 100% correct. The stock fuel pump can handle higher flow rates than 270cc injectors can produce, and can go up to 250hp, but that's on 370cc injectors and pushing the system.
The use of a rrfpr to increase fuel supply works directly against the fuel pump because it now has to not only supply more fuel, but supply that fuel at a higher pressure than it's used to, in the same ammount of time. DO NOT USE A RRFPR AND STOCK PUMP! EVER!
Just re-iterating what Drift Freaq said, but with more emphasis on the pump/rrfpr combo.

Ill add to what everyone has said so far. Im going KA-t and Im gonna be pushing it. Ive talked to alot of people, asked alot of people thier opinions and advice and looked at tons and tons of different setups. But what helped me the most in making my decisons was reading the book. It told me what I wanted to know. To be honest Moose, you sound like a honda owner. I get this question about 10 times a day :

"how are you going to put a Saab turbo on your Nissan???"

I want to sock and strangle those people. 99% of them are honda owners (other 1% was my dad:rolleyes: ) Im not trying to flame or anything. Get the book and read it, than ask questions and youll get your answers. I think everyone else whos replied to this post has given me some insight on my project in one way or another, but that was after I read. Buying a kit will make YOUR life easier. I did mine myself but I had some direction.

hey thanks guys for your input.

So what are those mags again? Maximum Boost, and... I'm gonna pick a few up and get into it. Check whether I want a kit or just a piece by piece set up.

Thanks for your reply's and I hope someone can infrom me on those books/mags.

02-16-2003, 01:24 PM
I don't know what mags were stated to look into, because I don't read every word in every post, but... in this post, Maximum Boost would have been mentioned.
Maximum Boost is a book written by Corky Bell. They sell it on Amazon.com and BarnesandNobel.com for about $20. I've never read it, but it is highly recommended reading both here and on FreshAlloy.
