i searched, and read about the debates with the mitsu’s smic vs. starion fmic etc. i have a chance to get a free smic off a 93 talon. i am just wandering if it will do as good of a job as say a 5" JRC would.
here’s my proposed setup:
-garrett t3 .42/.48
-dsm 450 injectors
-walbro 255 fuel pump
-manifold ? (haven’t found one yet)
-tial 35mm wastegate
-chipped ecu w/ turboedit
-intercooler ?
-homemade piping
you can’t beat free, so what are everyones thoughts?
thanx
oh, i’ll find room. i have some ideas up my sleeve.
yeah, i know all about south florida performance. unfortunatlly this is a budget build, so i’m looking for something used.
another question. what do i do about the pipe diameter, as far as the smic being smaller than my charge pipe to the throttle body. should i just get a reducer?
but i will say this… you are boosting a car… don’t try to cut corners… not to say you can’t do a budget build-up… but you will have to spend money on something
[QUOTE=thelate1]oh, i’ll find room. i have some ideas up my sleeve.
Dude I am currently doing a turbo build on my TEG I tryed to save my AC and other ish but it just worked out better to rip it all out AC, power steering anything non-essential to building WHP. This will make it way easier to put a front mount IC and to run piping…trust me on this one
PS I ended up selling most of the ish I ripped out to a friend and had enough from that to buy a couple parts …
i totally agree. i am not trying to cut corners, but the smic is FREE. i was reading on HT and a lot of people were saying that an air to air intercooler will only cool the intake charge to whatever the outside temp is(roughly). ie 98 deg. day outside= 98 deg. intake temp. whats the deal with this? if this is true, why even buy a fmic if you can run a smic for the same results(i’m saying this for the budget boost build). i know if your making serious HP that a fmic will surelly out do a smic in dropping the carge temp. thoughts?
as far as spending $ goes, i know i’m gonna have to spend. i’ll probablly end up spending it on a mani in the end. don’t sfp mani’s run like $450? i’m hoping to spend around $250. trust me, i’m not about cheap parts or doing this half way.
I used to run the DSM Side mount intercooler on my '90 GSX Mitsubishi. I had no problems with it. No leaks, rust, or anyting bad. Just fabricate some form of an air duct going to the intercooler fins.
If it’s free, the price can’t get any better than that.
Just don’t mount the DSM SMIC in the engine bay where it can get heat soaked easily.
Using a DSM SMIC is not necessarily “cutting corners.” (2.0 ltr DSM 4G64T engines, making 202 ft lbs of torque stock, can up the boost a little while longer before upgrading the SMIC to FMIC, and run 14+ psi on the stock SMIC.)
I plan on running my DSM SMIC when I eventually boost my Lsvtec.
When you get more $$, pick up a big Spearco Intercooler, and rip-up your front bumber. But for a garrett t3 .42/.48, and DSM 450 cc’s the small IC should be fine.
a smic is stock on that car… of course you gonna run it… i had one on my talon for a while and ran 12s
i never said a smic was cutting corners i was mainly talking about the manifold. i know what it can hold 15 lb before the fuel pump upgrade 17 with pump and hardwire kit.
i also have some questions on piping size. heres my proposed setup:
turbo to smic- 2"
smic to TB- 2 1/2
now when i make the transition from the smic to charge pipe to the TB, will i get lag since the diameter changes so much? since it goes from 1 3/4- 2 1/2.
Whenever there is a transition between pipe diameters transfering fluids (air is a fluid), the larger the diameter the pipe is, the higher the volume, but lower the velocity. The inverse is also true: the smaller the diameter the pipe, the higher the velocity, but smaller the volume.
In terms of lag, you won’t notice too much lag from multiple diameter intercooler pipes, as long as the transitions aren’t too drastic, but for other reasons, such as the VE, turbo specs, A.R., CFM, etc…will affect lag.
UCSlugRacerX- thanx for the insight. i will be running a t3 .42/.48 turbo. i hope it will satisfy my craving(for now). i plan on tuning for 8-10 lbs. i know this isn’t a huge turbo, but i wanted to progress gradually. i will most likely diss the internal wastegate and use the tial 35mm i picked up. thoughts?
The reason to use a FMIC vs. a SMIC is because it will cool the air more efficiently.
Yes, you can only use the outside air to cool either, but a FMIC has much more flow go through and over and they are larger (MUCH more surface area to cool the charge).
Remember that as air is compressed by the turbo it is heated up severly. The intercooler does the best job it can to cool down what the Turbo heated up before it enters the engine.
Hotter air is less dense (less power) and it is also more prone to detonation (dangerous).
If the side mount is free, then hey…cant beat it with a stick on a budget build, but a FMIC will always cool air better (and generally be less of a pressure drop).
with this setup, should i stay with the internal gate or the 35mm tial i picked up. piping would be easier if i kept the internal. whats the max boost i can run with the internal gate? which way do i thread the actuator rod to get more boost?
