max boost that can be run On a 1.8 without an IC
 

how much boost can safely be run on a 1.8 motor without a Intercooler, Is the limit 7-8psi , how much should timing be retarded to say run it streetable like for say one to two weeks. I was thinking of doing it the greddy way.

On the 1.6 greddy kit 6psi at 6* timing were recommended. Why take the chance and run it this way when you don't really have to. Get an I/C sorted out, you'll be happier.

or get a WI kit

Don't you hav an intercooler?

Did you sell both of them? Just boost it untill it explodes.:skid: :eek4: :cry:

I ran ~7psi intercooled for some time (a couple months). Ran 6° base before getting the Bipes, but that pinged a bit still. Ran 12° base and pulled to ~4-5° later with the Bipes.

I wouldn't boost over 6psi without an intercooler. You're going to have to retard to timing like mad and make your EGTs skyrocket.

I ran 6psi for ~6 months. Base timing 14, bipes pulled to 6 degrees.

Ok then It's just A ?, I have a Intercooler ready to install(12x9x2.5) But I still dont know how the hell im going to get 2.5 inch ic piping to fit with the a/c and p/s pump in the way...I just dont see how, its really crowded

I used 2.5" pipes but removed my AC prior to installing the intercooler. The way my pipes are routed would not work with the AC compressor. Sorry I don't have any pics of my pipes on my pc and my car's 2 blocks away in the -15 degree weather.

Is it hard to remove the A/C and how much extra room would I have to play with?

can this be a one day project?

I didn't remove any of the parts in the dash, but what I did wasn't hard, maybe an hour or so. It's also a good way to remove weight before you add the weight of the I/C.

Edit: are you sure you'd rather sacrifice AC in florida than just use smaller pipes before the intercooler?

but since I have both p/s and a/c I haft to get a belt for ps only don't I?

Yeah you need to buy the shorter belt for miatas with p/s and without ac. Most parts stores will have it in stock.

Buy Stripes piping kit for $225. It will take minimal effort to adapt it to your turbo. I'm talking minimal.

C'mon, don't you want to see him suffer in the FL humidity with no AC?:gay:

15-20 psi with water injection easily.

I have one i bought from FM lol. Their price was competitive and i added it onto an order i made one time. Of course i then decided to not retain PS.

Stock timing? Without an intercooler?

I'd like to see that:eek4:

Hopefully you will. soon

hmmmm That sounds nice, hmmm well taxes came in, I'll haft to make it a point to find out how much IC piping would be and the labor from a local shop, hmmm the big ? .....do I really need a/c I never use it unless it's to defog the windows:hsugh:

damnit, you're going to make my head pop one day.....buy stripe's piping kit and call it a day. At best all you'll have to do is cut the pipe a tad shorter into the intercooler and reposition the turbo outlet.

Where is that thread with it for sale?

Dude, there's a link right at the top of the page: MX-5Projects.com Greddy Intercooler Kit.

30 PSI.... On methanol.

45psi with makers mark or jim beam.

55psi on opium.

100 psi on LSD.

Lmfao

wow! now i cant wait to put my LSD together.

braineack you said strips Ic kit is for sale right? where is his add?

I saw that ....the price($500) was enough to scare me away? and it said 1.6 ,i Didnt know he was talking about that?

ah yes...i keep forgetting you have a 1.8. he is now just selling the piping kit for $225, but it would take a little extra work to make the throttle body end to line up.

what diameter Does he use in his pipe kits?

2" hotside, then it transitions to 2.5" down below before the radiator into the intercooler. Then 2.5" the rest of the way to the TB.
