that's a broad question. what are you looking for? how much power? i'm assuming daily driver.

Installed?!?!? Dont be a puss. do it yerself. If something breaks, you'll know how to fix it. Its not rocket science. Get a friend who knows a good bit about it to help you.

My setup isnt installed nor is it fully purchased yet, but here's a lowdown on the route I'm taking. Most of the prices are right, some are good estimates

$450 - Wideband Setup$700 - Upgraded T3/T4 turbo$425 - Revhard Manifold$10 - exhaust manifold gasket set$225 - Tial 35mm EWG$7 - Starion Intercooler...yes...$7$8 - JB Weld to fix starion intercooler$150 - 370cc injectors$200 - used SAFC to control Injectors$90 - Walbro 255 fuel pump$150 - EGT Gauge$60 - Oil pressure gauge$50 - Boost Gauge$150 - Intercooler Piping$50 - Resonator$125 - Muffler$225 - Custom 3" Exhaust and downpipe$40 - Air Filter$150 - BOV$75 - Oil feed/return line kit (yeah..im kinda a puss too, but hate shopping for bits ;))$50 flanges and gaskets$30 - Beer for any friends that feel like helping$200 timing chain kitThe ability to kill Camaros and tune my A/F ratio whenever i want....priceless

Unless i added something wrong, thats about $3600 dollars

If you wanna go the cheap route....

$200 or so to get the pieces for a custom manifold$50 t3 turbo off a z31$90 fuel pump$75 - junkyard intercooler$125 - FMU$50 - oil lines$50 - A/F ratio meter (semi-optional)$25 - Bosch BOV (sounds pretty nice, thou you'd be running closed loop)$200 or so for custom IC piping and downpipe

that comes out to $865

If you want to get it installed, that could easily cost you $1000 extra

I dont know how cheap junkyards in your area are. Here they sell turbos for $38.00 and intercoolers for $7. I got there opening day, so i was able to come away with 4 intercoolers for $28. lolz

Only thing I'd change is your exhaust route. Another $100 or so and you'd have a nice 3" apex/greddy/etc exhaust. And, a timing chain kit is $400+, not $200. You get a new waterpump, thermostat, and some more misc stuff with it as well.

Oh, and for that price you could have gotten a quality Nsport kit. :)

New turbos are great and all, but as said, it is just as good to use the z31 setup (from a '84 - early '87). Also, you could just get a log-style manifold made up real cheap and save more dough there, though im not sure how much that'll effect your power...

a t3 z31 turbo is as good as a .60,.63 stage III wheeled g3/t4 turbo with a 360 degree thrust bearing?

Sure, i could have a quality nsport kit, but it wouldnt have wideband and i wouldnt have the feeling of pride that comes with installing this bastard of a turbo kit that im putting together and installing. Who would choose plug-n-play simplicity when you could have 24 hours of hair-pulling, teeth grinding manual labor and frustration? ;)

Timing chain kit $400? damn, thanks for the heads up, guess i was looking at the wrong part. Best place to buy? After my last turbo experience, i might invest in an oil pump too

Oh yeah, i forgot to mention, im also going to run an MSD Knock Alert, and an MSD6AL/BTM too

Did i mention my motor had 170k on it? That shiz is gonna blow, but im curious to see how well it will do. transmission has about had it too, but i'll replace them when i kill the motor.

All of this stuff is going on a completely ****ty, stock looking 240. Huge dents and paint with 1mm of oxidization. Cant wait to start suprising the ricers :D

A turbo install will never, ever, EVER cost as much as you think it will. There are always little things that will nickel and dime you into next week if you aren't careful. Buy everything you need, then plan an extra budget of a couple hundred bucks. You'll break something, lose something or find something that needs replacing, I promise. That being said, you can do it for EXTREMELY cheap if you know what you're doing and don't mind being a little ghetto. AceinHole is running a nice setup for only a grand. He has a post somewhere around here detailing it.

Oh and like others said, don't be a puss, install it yourself. :) It's not hard, just make sure you do a lot of research and PLANNING beforehand, and you should be good. Set aside a few days to do it too.

Heh, I started my turbo project planning to spend under $1500. I've spent well over $6000 now. Ace spent under $1000. It depends on what kinda goodies you want. I absolutely HAD to spend over a grand on gauges....so I did. That kinda blew my old budget away in one single ca-ching.Oh, just to let you know, I didn't go all bling-bling with my setup, except for maybe the gauges. I get pretty good prices on some things.

mine started out as a $1500 deal too. Then i got realistic. Now im thinking about getting a real intercooler.

The stock MAF is supposed to be good for about 10psi right?

Yeah, around 9-10psi is the stock MAF's limit.

I want to get a different intercooler too, but no way in crap am I going to push that total amount up higher. I figure I'll enjoy it this way for a couple years, then go get a nice BB turbo, equal length tubular manifold, a giant frontmount, and a TEC III.

hey, since you seem so turbo smart, how much boost would you say that a starion intercooler is good for?

BB turbo = *drool*

I honestly couldn't give you a good answer for that question since I'm not totally familiar with the intercooler itself. You can run 15lbs of boost with it; I just don't know how efficient it will be.This is a cool site. Maybe it'll help you out.

Don't waste your money on a starion. THere is a better intercooler....i'll plead the 5th until i get my intercooler on ebay. It's too small for anything over 14+psi..it's better then nothing though.

some more numbers for ya at my site... see signature

I started out with a under $2k budget and I've spent $2.5k on the turbo and $2.5k on the engine so far. Jesus... this thing is starting to add up... but hey I also started with a 7PSI goal and now it's up to 18PSI... hmm haven't even test drived my car and the bug boost is already biting. :D

By the way, hopefully I'll be testing the KAT by the 13th of july. :ylsuper

You saw my cost breakdown. How else would you do it? Yeah, I spent a lot on gauges, but I figured I spend money there instead of on forged pistons. Why? I won't need them, because my car will be in tune....

thats my philosophy too. an engine can take a lot of boost IF its tuned right. Thats what ive always heard, i cant really talk from experience

do you need all those gauges, i mean i dont mind spending 2000 but what kinda hp gain could i expect, i already have a cat back so i dont need to buy that, if i could keep it under 2000 and i am a daily driver, what kinda setup could i work with

minimum gauges you would want are A/F and boost.

people buy gauges for a reason though. If i would have had an oil pressure gauge on my turbo prelude, i would have saved about 300 dollars and 20 hours labor.

Prices listed are for autometer, which is basically the bottom of the line as far as FI worthy gauges go

Oil gauge = $60Turbo repair/rebuild = $275Engine, transmission = $125 (thank god for good friends)

A/F gauge will give you an idea if you are running lean or not. If something goes wrong with your fuel pump and you run too lean, say goodbye to your bottom end A/F gauge = $55

Wideband gauge $500-$600. Replaces A/F gauge but lets you squeeze a lot of extra horspower out of your setup via tuning. Say goodbye to fuel management guesswork and fouled plugs from running too rich. This kind of at-home tuning could easily net you 50 hp on a nice setup.

Fuel Pressure Gauge $200? Running lean is bad, it makes stuff break. Im relying on my wideband in place of this

EGT - $150. Im not an expert on this, but gives you an idea if you are running lean and/or running too much timing.

Boost - $50 Tells you how much boost is reaching your intake manifold. No, your car isnt running 'faster than usual today' you've got a hole in the vac line that goes to your wastegate and you're running 5psi too much. If you had a boost gauge, you'd have known that already ;)

I don't know why you need gauges that you bought. All you "really" need are: water temp, oil temp and boost. Reasoning: do not need oil pressure because if ur leaking oil, the temp will go up much sooner than pressure go down/up due to lack of oil. Fuel pressure is good to know if ur running an fpr, otherwise it's useless (and FPRs suck in my opinion, they pose undue stain on fuel lines and injectors), cuz it's either around 40psi or it's not, and then u have problems anyway, which you should fix before u drive. EGT temps are useless, you will know if ur engine is running hot with a water temp gauge, and unless u drive and tune (hard to do, in a manual car), or have problems with ur timing/air-fuel ratio (which you should solve with a few dyno runs, not a EGT gauge) you really don't need EGT. Most people buy a huge amount of gauges, but never really look at them. The crucial ones actually show u if something is about to go wrong with the car. The rest are pointless, or just for show. This again goes for most of the turboed cars out there which are daily drivers and occasional autoX or track participants. If you are a professional tuner and need to have everything down to the last milibar and micro second, then u'll need to go digital anyway. I don't understand how an oil pressure gauge could have saved money and time (if there was an oil temp gauge present, if there wasn't, well... sucks). Again, water temp (to know if ur overheating), oil temp (same reason, and also a good indicator of how the turbo is affecting your system), and boost gauge (so you know ur not boosting 15 instead of 10).That's pretty much it for most of the people on this forum who want to turbo their KA. Yes, later if you're curious about what other pressure do or what pressure drops exist in ur system, or similar things, and you have money to satisfy that curiosity, then go ahead, buy 20 million gauges and stick them everywhere, and don't forget the 7" tach that goes to 10,000rpm, cuz u'll sure be needing that too.

That's 150 bucks AT THE MOST from autometer.

You can have plenty of oil and no oil pressure

When i lost completely lost oil pressure, the water temp gauge was normal. Bottom line, I think an oil gauge would have kept my turbo and motor from dying.
