water temp has nothing to do with boost. So it just has a boost issue and he's telling you it's because of the water temp. If it has the commander wait for about 15 minutes after getting in the car and then the water temp should be over 80C. Then boost and it will show the reading in bar you should get around .68ish for 10psi

off topic again

jspecracer7 you have the jic exhaust right? you made that video to show the sound? Well what bov do you have I liked it in the vid if it's you

thanks

yes, you are correct. the ambient should not have any effect on the boost or boost patter. the car will just 'get there quicker' if that makes any sense. i noticed minor spikes after i installed my dp last winter, and my buddy also has a third gen with dp, intake and exhaust, he's noticed a huge amount of response with the turbos when it's pretty cool outside.

i read thru it some more, and i can see how the ecu wouldn't allow the full boost if the engine is at normal operating temps. but for him to say 'it hauls ***' on a hot day just sounds wierd to me, especially if XS says it should be pushing more than 100 whp over stock with a tune. i can see why your concerned.

any car pushing 100+ whp over stock should be hauling ***, whether with a professional dyno tune or running a relatively rich PFC base map (FD's in particular)

you never listed all the mods on this car either. that would really help too.

i'm sure you could find someone on here who could drive the car for you to check it out (i'm assuming by now that it's not a local car for you).

TwinTurboTeddy or j9fd3s are a few guys that i would look into. i'm sure they would gladly check out the car for you

otherwise check out the other forum (rx7club.com)

Here is what he e-mailed me about mods:

what about the turbos

if he blew an apex seal the exhaust side is probably damaged on them

sounds about as modified as my last car minus the shocks.

honestly I would look for a stock car you dont know this guy and if he modded it correctly. If it doesnt have a warranty on the motor pass it up for sure.

Sounds like a secondary turbo problem to me. When I bought my car it did the same thing. When I removed the turbos the rear one was pretty well seized from old crusty oil build up. Of course I wouldn't call myself an expert on the twins being that I only had them on the car for about 2 months, and they never worked correctly.

Then of course there is the little problem with buying a car that has been driven around for 9000 miles with tuning for a stock motor on a side ported motor. Probably the only reason the motor isn't blown is that the turbo system is fucked. I can pretty much guarantee that the life of the motor was effected drastically. I would definitely pass on this one.
