Contemplating boosting my civic and have a technical question.

[thebluesky]

I've been researching the possibility of boosting my hatch. What I've pieced together in my head so far is the manifold, an internally gated TD05 off a 1g or 2g eclipse (would prefer the later as it is smaller), a spearco style intercooler, IC pipe routing, and oil feed and return.

What I'm a little confused on is waterlines and the exhaust portion. If I want to run the coolant lines, where and how to I run them? As to the exhaust, I kinda want to use the dsm o2 housing and run a modified stock dsm downpipe? Has anyone else done that before or know of a good reason why it wouldn't work?

My goal is to have a low spooling setup that will push between 5-7lbs max. I feel that this can be accomplished with the smaller turbo. I'm not looking to make a horsepower monster. That's what I have my Evo for. TIA

Ive seen a lot of people run DSM style turbos on Hondas without using the coolant passages in the turbo at all. They just plug the holes in the housing and have at it, typically the oil is enough to cool the center section by itself. I would definately recommend a 14b or 16g, as you know the puny t25's run out of breath above 5k anyway, and are nowhere near as efficient as the 14bs.

Ive also seen people run the DSM o2 housing and then modify a downpipe to fit(on singlecams you can even modify a 1g DSM d.pipe to work....may be something thatd work for you as well and be a good idea to look into...). I just so happen to have a 02 housing with an external dump if yer interrested...?

G/L man, keep us posted on what you decide to do! ....and lemme know if you suddenly feel like selling it...I have money thats burning holes in my pockets...haha

I've seen them do that, and have wondered why. Personally, I like colling benefit's from running the water lines, but that's just my preference. I guess I don't HAVE to, I just don't want to cook the oil more than I have to.

The 1st gen downpipe is exactly what I had in mind., especially as I have immediate access to one. As to the o2, I thought you would have been running that dump setup on yours. My only issue with running it is it would kill the stealth factor. Believe it or not, I was planning on even recirculating the BOV

Try maybe a Saab T3 internal gated Turbo, mine never ran outta breath above 5k rpm and it spooled Hella Qwik. Then you can also avoid the coolant line bull shnip as well..

There is a 1/4 line on the thermo housing. Pull it and put the turbo in the middle of your new line. This port flows coolant even when the thermostat is closed.

I have an extra one, a machV unit that Im not using. The dump was too short on it and it would aim it right at the oil filter... Plus its for a 2g so the 02 sensor bumg is clocked differently and it would hit the alternator, or be REALLY close. But, ya. Itd definately take the sleeper effect away...haha. No/little boost creep tho...

I love the one I have on there now, even though because of the route it takes I was unable to use the I/C piping that came with the FMIC kit...dammit!

That line goes to the throttlebody to help low the intake air temps. Realistically, I would be flowing in cooler air with the addition of an intercooler, so I could run that coolant line to the feed and have the return go to the throttlebody. Any thoughts as to why this wouldn't work?

Are you still using that setup or did you switch it up to something else?

T3/TO4E turbo now, The Saab Turbo worked fine till it blew,

It would seem feasable to me...you may wind up with a few idle issues due to the IACV, but most likely not.

And Ive heard of a lot of people using the Saab T3's as well, and actually have a freind that worked for Saab of Denver, who may be able to get you the hookup on a turbop, even a Saab frontmount (which will work VERY well for what you're attempting.

....or you could just say the hel with boosting it, and sell the whole car to me...dammit! haha:ring:

I've never seen a Saab front-mount. How big is it and will it necessitate really mutilating the front bumper?

They're prob around 30" tank to tank, available with side inlet/outlet, or backdoor style inlet/outlet, or same side inlet/outlet. Roughly 2.5" thick and only about 8" high, so no major cutting of the bumper would be necessary. They also have plastic end tanks, but as I said earlier people have used them to support 12 second passes, and if you're planning on using the Saab t3, it would be ideal, as its the intercooler origionally paired to the turbo...

[myshtern]

No you don't want to use a saab intercooler, you can just buy a cheap fmic on ebay or something. There aren't any moving parts so as long as it's mounted correctly, you shouldn't have any trouble with a cheap intercooler.

I used 13g turbo and it was great, the 14b imo on civics kind of suck - a lot of lag. The T25 would be great for everyday driving, lots of low end torque.

[hrcDSM719]

Ebay ones do work well also....I have an xs power unit on the Talon, and its a NIGHT AND DAY difference between hot/cold side.

I had a friend with an EVOIII 16g on his D16z6, who had full boost at 4krpm. I dont think the B18 will have any issues spooling a 14b, or even a 16g IMHO
