I've got a 2k prelude type-sh with a drag 3 turbo and aem ems on right now. I'm kinda confused of what to do next. Heres what I want to do sometime before I die. Could you guys just put them in order for me?
Upgrade intercooler---slowly, I mean slowly, collect parts to build bottem end---radiator and fans, I noticed my car's temp raises in stop and go traffic, is this a bad sign?---Suspension work---Intake manifold---head work
If you want to add something I missed your more then welcome
Thanks

 

boost controller, upgrade your fuel system, and dyno tune your car. a better radiator and dual slimfit fans wouldnt be a bad idea either... make sure you have enough coolant in your radiator and that your fans are turning on properly.

 

YES, that IS a BAD sign!!! It indicates that your car is probably running too lean. The fix is NOT bigger radiator and fans. The fix is fuel tuning on the dyno with a wideband a/f meter. Get your current setup properly tuned to run safely on the street before you do anything else!

i didnt mean for the FIX to sound like a new radiator and fans, i just mentioned that bc its always good to have. how much is your temp rising? i know i had this problem and it was a blown headgasket, i was also mixing oil with coolant as well as shooting out excess coolant from my reservoir. other good things are to check when your car does this is your coolant level, replace radiator cap, replace thermostat, and check for oil/coolant mixing. dyno tuning is a must for turbo's

 

VAFC
and get it dyno tuned

 

He says he has an AEM EMS; so the V-AFC would not be of any use to him. Anything the V-AFC can do, the EMS can do better.

But the key is tuning. With the AEM EMS, I'm assuming that you've had it tuned somewhat already because I've heard that the H22a is barely operable with AEM's "base maps"... Was this tuned by an certified AEM EMS tech? The AEM system is a VERY complex EMS to tune from what I've heard. The number of features it has and its versatility means you really need someone who knows what they are doing with this system and has used and tuned it before... If you are getting temperature spikes in everyday driving, the fuel/timing/boost maps are a likely issue. Tuning the low- throttle, low-rpm maps are key here.

ahh.. didnt see the EMS..
then yea.. the first thing I would do is go get tuned...

 

its tunned...
