DSM t25 turbo on a 99 Civic
 

I was looking at a t25 turbo for my D16Y8 and noticed that in todd's project he has no a/c condenser. Is it mandatory that the a/c be taken out to make way for the turbo? Is there any way that you can modify the intake to make it out of the way. my goal is to keep my car as streetable as possible. plus theres nothing wrong with my a/c!

Real men dont drive with ac.

Re: DSM t25 turbo on a 99 Civic
 

It totally depends on what manifold you use and where it positions the turbo as to whether you can retain a/c

Re: DSM t25 turbo on a 99 Civic
 

lets get this straight. I'm not about to take out my a/c and devalue the car because of a turbo kit. If the value would stay the same by taking the a/c out I would do it in a heartbeat.

for the DSM t25 isn't there only one turbo manifold for it, or possibly two from what i've read? I could fabricate my own but it would take way too long.

Re: DSM t25 turbo on a 99 Civic
 

There are various styles of manifolds , logs, equal length, top mounts etc. Some allow you to keep ac some dont. Oh and a turbo will devalue your car too.

Re: DSM t25 turbo on a 99 Civic
 

the turbo wearing out the motor will de value the car more than removing the a/c compressor. besides reinstall it when you sell it silly.

Re: DSM t25 turbo on a 99 Civic
 

I understand that a turbo would devalue the car as well, but i look at it as more work. I appreciate the info though. I talked to a few friends at my class tonight and they told me a few pointers as well. I'd call this case solved. im sure when im done with my install i'll be posting some more.

Re: DSM t25 turbo on a 99 Civic
 

If you are worried about the value of your car....dont turbo it.
Im sure a blown block will be great for the value of your car. Modified wiring and computer/ fuel components which u will have to remove.....and have fun replacing your oil pan....The AC takes 30min to remove. Just charge it when u re-install it.

Re: DSM t25 turbo on a 99 Civic
 

I guess when you put it in those terms...it seems simple. I already took an a/c class and i'm certified. for whatever it's worth, maybe thats why I appreciate it a little more than other people.

Re: DSM t25 turbo on a 99 Civic
 

Im not certified...but its all nuts and bolts....lefty loosy righty tighty...replace the o-rings...and charge...and proceed to lift the value of your car....

Re: DSM t25 turbo on a 99 Civic
 

pretty much, other than a few laws and procedures you have to know, it's not very complicated. you did leave out the most important step though, evacuation, or vacuum the system for at least 30mins after re-installation. and a bunch of other bullshit.

Re: DSM t25 turbo on a 99 Civic
 

i fi were you i would look into a slightly bigger turbo. i had a 99 civic with th eY8 motor in it and i felt that the t25 spooled too quick and dropped off way too soon. i ended up just upgradeing to a .42/.48 T3 from a Saab and was happier. only bad thing is that if you want to upgrade later then you have to buy a whoel new manifold because of the differant flange that the T25 has compared to the T3.

just my .02 and good luck with the set up.

Re: DSM t25 turbo on a 99 Civic
 

Actually that was my plan from the beginning. I found a really good deal on a whole kit and the only part the guy bought used was the turbo and manifold. I was just gonna use that turbo for awhile until I made enough money to finish off some bills and buy a new one. I was thinking along the lines of a t28. I've heard they're very fast spoolers and have good high end torque. thanks for the info though.

Re: DSM t25 turbo on a 99 Civic
 

A 14b bolts up the same and is way bigger than the DSM T2small. That turbo falls on its face almost instantly. Fast spool is pointless when you have no top end. Even better would be a 16g. Any bigger an you have to external gate. Even a $120 used 14b will still be loads more fun and only spool a little later. It doesn't fall on its face nearly at all at stock wastegate levels, but at higher boost and rpm's it still will a bit. The 16g is a damn fine street turbo for a smaller 4cylinder and won't fall off until super high rpm's and a ---- ton of psi. If your goals are sub 300whp the 16g will make those without even trying and doesn't lag nearly at all. Full boost around 3k rpm, but it spools way sooner; almost instant.

The only issue I see with you choosing a DSM turbo is that they are water and oil cooled center sections and you're only going to be oil cooling so that could lead to premature wear. My guess is you won't be running too high of boost, so as long as you're smart with the turbo it'll hold up fine. I definitely recommend stepping up to a TD05H Mitsu turbo though. It bolts on exactly the same as the little Garrett T25 you already have. You may have to get a J-pipe, but those are cheap and abundant just like MHI turbos.

Re: DSM t25 turbo on a 99 Civic
 

thats all very good information. I appreciate it. Like I said before, i think im gonna try this turbo out until I save enough money to buy a different one. but I will give all of those a thought. lots of possibilities. who ever said that I wasn't gonna be cooling it with coolant? and most likely im only going to run 9psi cause right now it's my daily driver. I don't really have any goals for this project, main thing is to get everything working reliably and have something a little more fun to drive than stock.


here's a pic of my car, speaking of performance... suspension, full exhaust, and header(which will be replaced) any other suggestions besides a turbo? this pic isn't the most recent, it was taken back in the spring, only minor changes since then.

u dont have to water cool the turbo ......just dont rape it for the last 2-3min of ur drive.

Re: DSM t25 turbo on a 99 Civic
 

wouldnt the HF manifold allw you to keep your ac?

Re: DSM t25 turbo on a 99 Civic
 

that wasnt the case in my EG....

Re: DSM t25 turbo on a 99 Civic
 

yeah...i think imma just remove the AC fan...lol...should have room to keep AC if i use HF mani...

its so hard to find one for a good price these days

Re: DSM t25 turbo on a 99 Civic
 

my compresor hit my turbo....that was the biggest prob....but boost + windows down = more cooling than AC ;D

Re: DSM t25 turbo on a 99 Civic
 

Actually if you remove the a/c fan your a/c still won't work, because it won't cool it down enough to change it from a gas to a liquid in the condenser, and your high side pressures will shoot up to about 500psi within 10sec. Causing your high cutout switch to come on and shut off your a/c. I've decided to either buy a different manifold or take the a/c out all together(except beyond the firewall). just make sure if you do, you get it recvoered before you do it. BIG filnes if you get caught.

Re: DSM t25 turbo on a 99 Civic
 

what? :S

Re: DSM t25 turbo on a 99 Civic
 

your car is riced to bloody hell. atleast you're going to install a turbo. you should go with a t3/t4 not no punny t25 you'll regret the t25 in a week after the install. ;D

Re: DSM t25 turbo on a 99 Civic
 

any T3 manifold is more versitile but he did say he got it for cheap so he might as well use it till he can upgrade, gotta crawl before you can walk ;)

Re: DSM t25 turbo on a 99 Civic
 

thats exactly what i'm planning on doing. I have to sell my regal before I can upgrade anymore. anyone want to buy it?

clean regal, i sold mine a few years back wasn't close to being as clean as that but had hydros and would hit 48" with a few hits of the switch ;).

Re: DSM t25 turbo on a 99 Civic
 

That's pretty sweet man, I thought about going that direction, but I was only a sophomore in high school when I first got it and I didn't know ---- about hydraulics. So instead I dropped a shitload of money into making it a street rod.
