Turbo Experts

Ok you guys are my turbo experts and I need some help with an app outside of a Mitsubishi engine. I'm installing a mitsu turbo from a gst or vr-4 on a d series honda engine. I want to run about 8-10 psi. I know I need an intake manifold, exaust manifold, inter-cooler, oil lines, new high flow fuel pump and injectors, and the turbo (of course). I'm also installing a turbo timer, boost gauge, a/f meter, and an engine management system. Would an FMIC be too much, have I missed anything, is there anything I shold know that would make the install easier, and is there a way to control the wastegate on the turbo. Thanks again for the help guys. I can't express my appriciation for the help you've given me in the past and how much your input on this will mean to me. If there is anything you need to know I'll do my best to answer your ?'s.

Don't forget that you will also need a blow off valve and a boost controller to manage your boost levels. :)

Since your using a mitsu turbo you'll need coolant lines to

Should I Replace my radiator to ensure better cooling for the turbo seeing as how it's going to need coolant lines?

I don't think its necessary

You have all your parts? I have a few things laying around that I could probably sell.. 1g sidemount intercooler,1g upper intercooler HOSE with the 1g BOV flange of course,1g throttle body elbow, 1g lower intercooler HOSE, 1g exhaust manifold, 1g o2 housing, 2g exhaust manifold, 13g turbo, 14b turbo(that needs new bearings!) and probably a few other things laying around.. If you would want any of this stuff, I'm sure we could work out something. Good luck.

I have a whole list of things for sale on page 6 of my cardomain. Link in my sig

or you could post this in the honda section??? Most of us don't know a damn thing about turbo'ing a honda.

No offense, but why are you turboing a D series? Swaps seem so cheap and easy coming from my Honda friend, I'd drop in a B16 before you worry about turboing it.

swaps are easy but the motors are kind of pricy. I know a guy from Owatonna thats running a turbo d16y5 and hes making 290hp to the wheels so I guess its not a bad motor

You also won't need a turbo timer on a stock mitsu turbo. Unless you want one just for shits and giggles.

swaps are easy but the motors are kind of pricy.

Really? I read in a tuner mag that a B16 can be had for around $500. But I'm not sure how much one really is.

When they say 500 that's if your lucky enough to have the cash available to get it before someone else and that's only the motor. Swapping isn't as easy with a Honda as it is with some other cars. Not only to you need to swap motor mounts and small parts but you also have to swap ecu's, harnesses and a crap load of other things especially with the VTEC engines. I won't say it's as hard as swapping to a 4G63 from a 420a but its close. I think the biggest difference is that there are many companies that make kits to do the swaps. I didn't post in the Honda section because it's all the same crap over and over and no one is really into using the mitsu turbo's. "Oh your going to go turbo?! You need a Garret T66 pushing 20+ PSI!" Screw that. I don't want a drag car. I want a little more power than 102 hp at the fly. If I wouldn't have asked you guys I wouldn't have know that I needed the coolant lines. I haven't seen that on any of the Honda sites or any of the Honda forums. The D series is a good low compression engine that will hold well to a turbo pushing small boost. I just want to get into the 200-230 hp range at the wheel. My trans can handle 300.
I also thought that the turbo would have a longer life if you used a turbo timer. Is that only on heavier applications? And for the boost controller, wouldn't the wastegate work just fine or is the controller used to control the wastegate. (This is why you guys are my turbo experts.)

Turbo times are good but not required, and a boost controller controlls the wastegate yes.

Is that only on heavier applications? And for the boost controller, wouldn't the wastegate work just fine or is the controller used to control the wastegate.
I would get a turbo timer, it will keep your turbo in good shape. Big, small, cheap, or expensive, I still think its a good investment. Plus I like the digital RPM guage on there.

If you are just going to run the waste gate boost, you should be fine without a boost controller, but you are screwed if you want to turn up the boost. I see what you mean about the D series, I assumed that you were making a balls out track car. If all you want is a little extra power, more power to you. What turbo are you planning on? Good luck man.

I really want to use one from the 4G63 of a 97-99 model. Something with low miles is good. Like I said, I just want 8-10 psi, not much, just enough to be effective. It'll push me into the 200 whp range. I don't know the model number for the turbo. I'll end up pulling it for myself at a local Junkyard unless I find a better deal on the net. I can get an FMIC for 17 + tax and the turbo for 40.

T25 huh, I might have one to get rid of if your interested. I can get you a price tomorrow

I edited my post. I can get a turbo for 40 bucks and a FMIC for 17

$57 for a fmic and t25? wow

if your close enough to one of their locations they're called pull-a-part. They have like 5 or 6 locations in the south east. http://www.pullapart.com It's going to make it cheap for me to get the parts I need.

Whats the intercooler off of?

See I could get a full B16 or B18 for $107. The problem is selection. Their cars go fast.

I'm going to pull one off of a ford turbo diesel. I know someone here that's already used one and it fit with little modification to the bumper.

:lol: Thats a big fuckin turbo homeboy. I'd go 14b, cheap easy to find turbo and seems pretty good for your application. I dont think you'll see 200+ whp on 8 lbs of boost, but it will get you close.

EDIT: I dont think that D series is going to hold together at 8-10 psi.

all the turbo diesel intercoolers I've seen are f'ing huge like bigger than my radiator which would make it like 6 times the size of the rad in your honda lol ;)

oh crunchymilk, where would we be without your helpful insight? Anyway, I think using a monster fmic like that is a tad retarded, no offense or anything, I think swaps on the honduh's are a little overated for the price. Props to you for turboing your car and not just having neon lights and a picture of good ol' Vin Diesel, I would suggest that you get t3/t4 turbo, or the 14B... that is more than enough power for your light weight car, If you go any bigger you may deal with turbo lag, or your stock internals just shread to hell because they can't handle the PSI. It would be a waste of money and time to have a big turbo running at 7-8 PSI. I suggest a smaller one to maximize the smaller turbo, but whatever you do GOOD LUCK

I wasn't planning on using the turbo from a ford, just the intercooler. I would be utterly surprized if my little 1.5L could crank out enough exaust to work a turbo that big much less to push enough to be effective. Ford had one F series that the intercooler wasn't HUGE. Its between 94-99. My other option was to use one from the SRT 4. It's just going to be harder to find. I don't expect my stock internals to get me to 200. I've already lined up a set of forged internals and I'm getting ready to replace my ignition. Next time I have a free day that I'm not playing taxi, I'm going to port and polish the head. I've got a lot lined up before I boost. I want to make sure that I will have as little problems as possible.

Since the Mitsu turbos are water cooled people question whether a turbo timer is needed. You can get a used one for $30 and a lot of alarms come with them, so it couldn't hurt. I just let mine sit for a min. or two before I shut it off.

My brother's '94 Integra LS is making around 270whp without internals on a big Garret at like 8 psi. So I guess some of them can hold some power on stock internals.

e bay IC. See them for under a 100 bucks now. Just do that.

The B18 is a little beefier than the sohc D15. Good luck though man, pics would definately be appreciated.

I will definately post some when I get started.

7-10 psi... isnt that a little high for a stock D series motor? do you have that motor rebuilt for turbo? I dunno, but i usually hear with the correct amount of mods just with the stock D16 motor, the limit of boostin psi is like 5-8 psi of boost.

The D16 is good for about 200 hp at the most on stock internals (assuming its in good shape to begin with) To be safe you should use ARP headstuds, a new headgasket. The biggest part is that you get a good tune. You need like 330cc injectors or larger I believe. Also a bigger fuel pump, I think you mentioned that already. Check out www.turbod16.com they have tons of info. They have some D's running in the high 300hp range. You can get an intercooler on ebay.

If you're looking for a little extra power, why not save yourself some money. Just swap the head from a D16z6, change the cam, cam gear, pulleys and do a Hondata chip.

You're talking about what's called an LS/Vtec swap, and it's more trouble than its worth. I want to learn forced induction from hands on experience.

UPDATE Replacing the whole body, next is the turbo!

This thread is over two months old. DO NOT post in something over ~2 weeks unless you have something important to add to it, ESPECIALLY if it has something to do with Honduhs

yeaht thats what i did

I know this thread is old and no one likely cares too much about that^ post but I'm just trying to be accurate. So I guess I was wrong. His car DOES have internals (forged pistons, rods, stock crank?). And it was tuned to around 17:1!!!:eek: Running like 7 psi or around there with a T3/T4 (very vague I know, but he doesn't know the specifics). Burned up the engine and needs everythig replaced now. Should be good when it's fixed though. Anyway, good luck with your project fiberglasscivic.
