A friend is giving me an intercooler from a 95 Eagle Talon TSI, I believe it is a side mount unit. I am using a B16a (stock internals) and only plan to boost between 6 to 8 lbs. The IC should be enough to do the trick with such a small turbo, but when should I draw the line with such a small IC in comparrison to turbo size?

Any thoughts are welcome...

 

intercoolers arent that much so unless your hurting for cash i would just run a front mount

 

I do see your point, but I am still inclined to use the sidemount IC just becasue I already have it. I am not really looking to gain a "too" more power or anything like others who like to go all out, so I figured this would be sufficient for my needs. Are there a lot of drawbacks for these that I am missing or something?

 

i have no experience with side mounts but you would think there would be cooling issues. and where are you gonna mount this cuz its gonna be a custom job. and stock gst's were only putting out 200ish hp so i cant see them being very efficient.

 

Actually, I am glad you said that becaue you are right. Buddy who has the IC for me actually is swapping his engine to a later model convertable Mitsubishi GSX. He sasy the engine puts out about 220 to 240HP, can't remember. What I truly intend to do here is use the IC and a small turbo just for small gains. Then build the engine slowly as I go. I have some small basics now but I intend to do a bunch over the next 7 months. Do you (or anyone else for that matter) think that this IC I am talking about will be sufficient for whatever a simple 8lbs turbo on a B16a will push? I know I will eventually have to get a larger unit, I am just wondering what a good safe range would be once I have things in working order.

I believe the IC is mounted in the pocket area that the CAI filter head would sit. I have seen done before and don't see it being too much difficulty.

8 pounds on a b16 all depends on what manifold engine managment blah blah. you should be fine but that intercooler was made for 220 flywheel horsepower when it was new. now its 10 years old? technically you dont have to use an intercooler so any should be better than nothing

 

ok, I see what you are getting at. I am not too sure if an 8lbs turbo would put me too much higher than 220hp anyway. Thanks man...

 

What turbo are you planning on useing? I run 7.25 on my b16 with a t3/t4 57 trim. I dont know how much Im putting down but I know others with my setup are around 220-230 with 7 and 250-260 with 9.

 

Wow, that is an impressive response to small input. I do not have the turbo yet but I am looking. I do not know what to get. I have heard of T3/T4 turbos but I do not know what they are or how they equate to trim level. Are these turbos you speak of mitsubishi 1st gen turbos?

 

A friend has an SiR B16A converted to obd1, 60trim t3, ss-autocrap mani, previous owner said 270whp at 9psi. He also has the $185 johnnyracecar 6" FMIC. I just got the $155 6" version, great quality. You can sell the sidemount for $20-40, so just a couple hours of working will pay for the fmic.

I'd say a volvo t3 50 trim (typically the .42/.48 turbo) is the smallest you'll want to run on a low boost b16.

 

I think the IC will be just fine for what you are doing . You have already recognised that you will not be ringing the hell out of it . Just make sure that you are getting sufficent airflow to and from it . Engine amnagemnt is key in what you are doing . Experiment and have fun with it . It will be all the more rewarding building it up peice by peice .

Good Luck

 

you also have to realize that a very very large percentage of honda turbo projects use intercoolers that are 2-3x bigger than needed.

 

Having used a SMIC on my SR20DET for a while, then going to a FMIC - I'll say just go with a front mount from day one. You're talking about $150-170 for a decent sized intercooler up front(something like 7-9" tall and about 20-24" core width is good).

Having cooler charge air *really* helps a boosted engine. The SMIC will keep your temps down to a reasonable level, but a FMIC isn't much money or any more work at this point so honestly just go with it from the get go.


SMICs are so small they tend to heatsoak really badly too, so you might get 1-2 gears of good pulling then feel the engine slack off from the hot air.

 

To answer your question the side will do you fine, until you have the money to upgrade obviously you said you do not have the money to get the fmic, so just run the side for the time being

 

OK Having read your responses, the general motion is for the fmic understandably. The smic will be efficient for the meantime however which is what I was looking to find out. I appreciate all of the opinions here. My goal is to remain as inconspicuous as possible and have a good, healthy, and "spirited" car. So then I could pose another question being that my first is pretty well answered.

I have heard of some turbos (some made by Mitsubishi) that are relatively quiet. I am looking for the quietest turbo that I can get. I have searched (archives and all) and what I have come up with is people asking if having a quiet turbo is normal, and then some exhaust questions.

Question 2: What turbo would be good if I am just wanting to push 8lbs and be as quiet as possible???

You guys have been helpful, thanks a lot...

Get something internally gated,maybe a t3 42/48..Get a quiet exhaust..Run a bosch bov back into the intake pipe..And run a pipe and filter off the turbo..Should be pretty quiet..But all turbos are gonna make some noise,..

 

Wow, that was pretty right on. I can see how this applies. It seems simple to think about it, just "internalizing" the noise.

Funny thing about htis is that I understand everything you have said just from doing my homework, but I still do not know what to make of "t3 42/48." I have heard t3/t4 (I assume the t4 is larger), I have heard trim levels of 57- 60,... and they make about as much sense to me as my girlfriend does. If anyone has any patato-head examples for me it would be much appreciated.
