Yeah, I'm thinking it can't hurt, but like you say I don't know what their purpose really is so I'm not sure if i'd be losing anything should I close them up.

I'll probably give it a shot on the rebuild.

 

Those ports in the sleeve allow exhaust gas to circulate to the outside of the sleeve and out one of the two small holes just below the exhaust port. If you're not running a full emissions system then their not needed and most likely blocked by an aftermarket manifold anyway. No problem with closing them off.

 

Excellent info!

Plugged they shall be

 

anymore tips tricks of keeping a safe setup without cracking open a motor?
anyone run different oil, different stuff in the water, im looking to cover all the bases here one step at a time...

 

How are you dealing with the intake air as far as heat is consernd?

 

One seemingly pointless one would be an actual intake. (haven't viewed you pics in a bit but I'm not sure if you've got one?)

I noticed cruising air temps went down a few degrees after running an intake and filter that ate nice, cool air from a bumper vent as opposed to my old setup with a filter directly on the turbo. IIRC, it was about 4-5C (average) cooler vs. ambient temps with the intake.

Granted, I do have a nice bumper vent feeding the area also, so I'd expect minimal gains going from one area of the heated bay to another.

 

i know its not the cleanest setup but im working on it...

 

Wouldnt hurt to find a cooler source of air for the turbo if you can find the right path to get there.

 

I went for a ride yesterday with the outside temps at 95 degrees 80% humidity and in traffic the water temps were running 184 deg then i went to the freeway and did a 2nd and 3rd gear pull to 110 mph and the temps did go up to 190 but started down very soon after letting off, thats 20 lbs boost on 93 pump only.

Ive noticed that in the high 70's and low 80 degree temps is were it really works good but i was pleased at 95 it still cools very good.
I decided im not raceing the car with temps in the mid 90's its just too hot the car might be ok but im not!
Someday ill learn how to log and have iat # to talk about.

 

I like the shield Busted7, I am actually fabricating one for myself. I wonder if coating the shield woth some of that DEI thermo protection matting would improve deflection, granted you keep some space between the mani and shield?

 

disregard last post. I really need to start reading all the posts in the thread.

I will have to use the dei matting.

 

pics when done?
ive never been "crafty" when it comes to sheet metal or making things like this. thats why i like to see others ideas....

 

will do.

 

Here is 1 of the 2 sheets I am fabricating. This only needs the dei heat matting and will be finished(maybe round corner for asthetic purposes). The other will be a little more tricky due to less spots to bolt up to W/O touching the LIM. They will overlap like Busted7's and hopefully will be benificial.

.28 sheet metal from ACE.

 

It looks like your getting it and i forgot it takes two pieces for the shield since theres two diffrent angles and the hot side of the turbo.
Im also going to fab shield for the underside of upper intake plenum.
I also need to dei the intake shield off of the koyo rad.
But mostley i need the time, i thought the economy was slowing but not in heating and airconditioning.

Let us know how it works.

 

awesome!
looks good mate!
im guessing the turbo had to come off to put that on or did you squeeze your hands in there? looks like a tight fit.....
may i make a suggestion though?
i wrapped my DP also and im kicking myself in the pants for not putting at least 2 layers on it (unless its ceramic coated also). i can touch it after long idles but driving its very noticeable (the heat) in the cabin....
im going to have to see what overlap your talking about because i cannot picture it at the moment?

 

I also have dedicated my build up to remove heat.

 

For the Coolant system i am using Evans waterless coolant to keep from having any hot spots in the motor, my temps stays 175-185F 24/7
My oil temps stay around 160-180F
The Heat rap cuts the heat down ALOT...

 

wow you even painted the fan blades, does that help in cooling?!? ? ? nice car
did you remove the coolant overflow and wiper overflow?
also do those rubber flexi hoses hold up? i'm afraid mine will break one day

 

Is that a water pressure switch / sensor in the second pic ?

 

Yeah, put it on with the turbo still on the engine, was a bitch but I have crafty hands. I am thinking about not overlapping. The sheets only come in 6 1/2 inch wide panels SO I will just make it make flush.

I will have to wrap DP again, thanks bud.

 

Hmm, this in encouraging, maybe I'll head up to 20 PSI now, lol. I'm running 93 octane with high compression (s5 NA) rotors and NO trailing coils at all.
Do you guys think trailing coils make that big of a differance at higher boost levels?

 

That is a Water temp warning switch, if the water goes higher than 210 it will turn the warning light on my gauges. I have high temp warning lights for everything, Boost, Water, Low Oil Press, High Oil temp.

I have removed the Coolant overflow, but still have the wiper bottle, The flex hoses have been really good, no complains, have had them on there for over a year and they are still like new. But the coolant that i am using doesn't break hoses like normal coolant does. All the small rubber hoses are the High Pressure fuel lines, they have a plastic inner tube then the normal outer rubber. This makes them stronger.

 

man, i need to get home and take some pictures of my coolant setup, after I fixed that leaking vaccume cap that was on the back of my water pump it's been cool as a houston vacation!

And both my coolant and oil temps cimb well over 200 under boost.... but at least it stays under 190 at cruise now that I have some ducting in there.
But I don't want to get this thread off course....
Has anyone else experimented with 87 octane on a turbo car? Had it kickin' pretty hard and 4psi before detonation, but my trailing coild weren't firing properly so I just unplugged them. With no T coils I'm thinking I can hit some better #'s than 4psi before detonation. I'll get back with you guys after I do some more experimenting.

 

so i just ordered this today:
http://store.summitracing.com/partde...0&autoview=sku

soon im ordering some 4 inch elbows and whatever i need from here:

http://stores.ebay.com/GREAT-AMERICA...QQftidZ2QQtZkm

decent prices for 4 inch i thought. if you know anywhere cheaper im all ears...
not to many places nearby that sell 4 inch tubing so im stuck with paying shipping price....but
im using it for a CAI....gonna go this route:

https://www.rx7club.com/showthread.p...0&page=5&pp=15

i ordered the DEI mating for a shield between the LIM and turbo.

so if im doing something wrong please let me know....or if you have better ideas im all about it!!
