Hey everybody, few questions

[DSMagnum]

Hey everybody! I recently registered here a little while ago. I have been over at DSMtalk for a while now. I bought my 95 GS-T about a year and a half ago and fell in love with DSM's. It's only got 98,000 miles on it, and it has never seen snow, which is not common in Northern Michigan!

I am finally getting around to putting some aftermarket parts on (I wanted to get the maintenance stuff out of the way i.e timing belt, hoses, plugs, wires) and I recently purchased an Injen Intake. I know, I know, people are going to ask me why I spent the money, but I believe crap in equals crap out so I always go the high road. Plus I love my car too much to put anything less then the best on it.

Here is my question tho, it's just a run of the mill Injen intake, but it works in conjunction with an aftermarket BOV (GReddy S-type is what I am buying next). Here is the link to help out: http://cgi.ebay.com/ebaymotors/INJE...38634QQitemZ8034949904QQrdZ1QQsspagenameZWDVW

This will work for a completely stock set-up right? I won't need to upgrade anything to make this part work, other than an aftermarket BOV. Would a 1G BOV work with this?

I am also purchasing RRE's Upper and Lower IC piping kit seen here: http://www.roadraceengineering.com/parts/greddy/greddypipe.gif

These parts should all work together right? Like I said, I am new to this type of engine, so i want to make sure it will work. Soon enough, I will also be picking up an Apexi N-1 full 3" exhaust. With the IC piping, intake and exhaust, what gains can I expect (in hp)?

Thanks for the help, and hopefully soon enough I won't have to ask so many questions about things fitting or not

The injen intake and the rre upper ic pipes go in the same location so don't buy both it's basicly the same part just different shapes and brands but they will both attach to the intercooler and the tb with a blowoff valve.

The Injen Intake you've listed from E-bay looks like it's made for an N/T model. Although they're describing it as a turbo part, the picture is incorrect. As a matter of course, there are other intake manufacturers other than Injen who povide an excellent product at a fair price. A better example of what you'll need can be found here:

As far as your BOV choice, I would recommend a 1st Gen BOV since it's already setup to recirculate and will hold 20-21psi before leaking. THE RRE Pipes look like a good idea and DejonPowerhouse also makes similar piping setups as does Buschur Racing. When you purchase the upper pipe, have them flange it for a 1G BOV and you'll be in good shape.

As far as HP gains, we generally don't discuss this in the forums as it's considered bench racing. The turbo will be the next thing to hold you back, howver, as the T25 is very small and doesn't have the capacity for high airflow or high boost.

Welcome to Tuners and good luck with your project!

It said that it was for a turbo eclipse 95-99, and the picture said it may not reflect what the real product looks like, so I am crossing my fingers hoping it is right. Now I was wondering about the intake and the IC piping being the same?? Does the part of the Injen intake replace the lower IC piping?

I will check out those other places too for parts, and I appreciate the quick responses.

Mike,

The intake is separate from the upper and lower intercooler piping. The intercooler piping joins to the turbine outlet (cold side) and then feeds and exits the intercooler up to the throttle body. The intake houses the MAF sensor and joins to the compressor inlet on the turbo. Adding an intake leaves the upper and lower piping untouched.

I would strongly recommend that you call the e-bay vendor as there are two different versions of the Injen. You want the one with a recirculation tube that will allow the BOV to vent back into the intake. Failure to do this will result in sloppy idle and a rich condition between shifts since the MAF will be counting on the vented air to be returned to the system and will add more fuel as a result.

I've attached a link to my gallery so you can see a shot of my engine bay and get a visual picture of what I'm talking about. Understand that because I use a 16G turbo, that my lower pipes are different than what you would buy for the T-25 and other downflow turbos.

Let me know if that makes sense,

The blow off valve bolts to the upper ic pipe. I believe that Andy is right the injen one is for a N/T model.

 

[DSMagnum]

I took your advice and just e-mailed the seller. Now, would the fact that I ordered the intake made for an aftermarket BOV make a difference on whether or not I get that recirculating tube? It had me specify which one I wanted, and because I was either going to do the GReddy or the 1G, I chose the aftermarket one.

I really hope I didn't order the wrong one. This could suck.

Mike,

Chances are that you should have ordered the stock unit since the type of BOV is determined by the flange on the upper intercooler pipe. Typically, the stock units are made to recirculate on the intake while the aftermarkets are not.

You may want to confirm this with the seller and ensure that you're receiving the correct part with a recirculation tube. If not, it may be easier to speak to an e-bay representative, explain the situation and cancel the transaction (unless the parts have already shipped).

Let us know what you find out,

Andy

Just get a 1g BOV and save the extra money you wouldve spent on the Greddy Bov to buy a Boost gauge (if you dont already have one get one before you do any modifications) and a Joe P. Boost controller.

 

[DSMagnum]

Well I e-mailed them and this was the response I recieved:

we gonna ship out the IS1890 with the recir return tube for you

KM

So I am hoping that it will be right

Yes, you'll want to recirculate the BOV until you get the parts to vent to atmosphere properly, if that's your cup of tea.

The link you gave us is the diagram for the Greddy intercooler pipes. If you order these, the only BOV you can use a Greddy-flanged one. If you want to go with a 1g BOV, you'll want to order RRE's Upper Intercooler Pipe and just choose the 1g flange option. If you decide to go with a different BOV or just want to shop around, I'd recommend checking out dejon. His stuff is very good quality and he offers a wide variety of intercooler pipe colors (good for color-coordinating an engine bay) and BOV flange options.

Edit: Just saw that Andy mentioned dejon, too.
