Since I'm planning on purchasing a 2003 s2000 and building it with an inlinepro turbo kit. I was wondering what everyone was doing as far as combatting the extreme engine heat created by the turbo. Are you guys heat wrapping the turbo's?

Thanks in advance,

Vented hood, heat wrap downpipe, heat wrap turbo manifold, mugen thermostat, mugan fan switch, oil cooler and Koyo radiator are a few things iv done to help with heat...

 

I havent done much other than an oil cooler right now...but i really need to do something cuz my coolant temp while cruising on the highway is around 205-220 degs... Much higher than what I'd like. I'm planning on getting a mugen thermostat, upgraded radiator and fans.

As far as a fan switch... I'm just going to use EMS to have the fans turn on at a much lower temperature rather than getting a switch...


oh and a vented hood would be a good idea, but the one that I want is stupid expensive so its smarter to do REAL cooling mods like the ones I said rather than getting a hood with some holes, lol

 

Jet-Hot coating on mani, turbine side, and down pipe

 

What kind of heat wrap are you guys using? And where can I get it? Thanks!

 

Thanks all for your great advice...After a bit of thinking I am going with Jet-Hot coating on mani, turbine side, and down pipe. The coating is good 'till about 1300 degrees (Hopefully I won't run anywhere near that).

Just contacted Jet-Hot and the prices are as follows on the Sterling Silver coating...

Manifold - $150
Turbo Housing - $85
Piping - $20 per foot

I believe these prices are reasonable for a great solution

That and it keeps your turbine housing from getting all brown and rust looking. Also looks better and works better than heat wrap.

 

I have the same coolant temps as you between 205-220 degrees depending upon whether i'm cruising or sitting in traffic, but I thought that this was about normal.

 

I guess it might be okay for a turbocharged setup, but from what I see based on the temperatures that the Mugen thermostat and fan switch work at, NA motor temperatures are considerably lower. For example, look at the Thermostat... the stock thermostat opens at 76-80 C... which is 168.8-176 F. The Mugen one opens at 68 C, which is 154.4 F.

The stock setting for the fan to turn on is 93 C (199.4 F), the Mugen one changes that to 80 C (176 F).

(BTW I got all of these numbers from kingmotorsports.com)

Besides all of this, I remember reading threads in FI where people with turbo setups have coolant temp warnings to come on at around the temperatures we are currently running at. I can look for these threads again if you'd like.

The other major issue for me is that if I'm pushing the car even for like 2-3 mins the coolant temps get WAAAAYYYYY out of hand. Back in april going to the dragon we decided to take a side road. My coolant temp was at ~240 F within a few turns... I almost had a heart attack and started running my heat on an already hot day sweating like a pig just trying to cool the motor down as fast as possible... all while screwing up the drive for the people behind me cuz I had to start driving like a little pansy.

So with all of this in mind, I've been planning on getting mods that would lower the coolant temps and work efficiently to keep them low even under continuous load..

 

Is your turbo watercooled?
