hi guys, was out cruisin last nite wen i felt a loss of power, was pushin it a bit at a 120 in forth, now it seems 2 be runnin a bit chuggish, was rebuilt 5000 miles ago, there was no smoke so im guessin it was\'nt one of the tubs, checked all fluids this morning and everthing ok, there\'s no leaks or coolant loss and it started fine, ....in myself here guys as i car\'nt afford to fix it, any help wud be seriously apprieciated, cheers.:xconfused:xconfused:xconfused
Has one of the intercooler boost pipes come off or even loose? Check them all carefully,also holes or splits in hoses.

if you were doing 120 in fourth you were pulling 7k so maybe you have chipped a tip.
When its idling do the boost guage fluctuate at all?
boost reading as it normaly does but deffo lost power, checked all the boostpipes i can and had to tighten 2 up, still feels chuggish tho, i live in the north east shud i take it to mazda, dont no wat 2 do:reallymad:reallymad:reallymad
i wouldnt take it mazda, most of the young lads working there have never even seen a rx7 never mind work on one.
You need to go to a rotary specialist, the only one up in the north that i know of is WGT, hes not cheap, but very good with solving problems.
There is hayward north which is actually closer now i think about it, id try them out, number is 01302 726763 and ask for steve
cand haywood north do compression tests also i want the map looking at, cheers.
does a chiped tip mean rebuild time or is it fixable:2Confused
chipped tip is rebuild time, they can do everything i think, give them a call on monday.
saw rolley today mate. told me you tested it as i said, and got less than 3 bar accross the two rotors. :( sorry mate.
seems like all i ve been doing is helping people to diagnose rebuilds these days.
on the other hand im a bit of vulture so if your breaking i might have some bits off you lol
oh and will you text me rolleys mobile number please fella. forgot to get it off him.
yeh gutted m8, let me know wat ya want cos icarnt afford 2 fix it, shame aswell cos it supposedly had 5 grand rebuild last summa and i\'ve hardly used it, anyway cheers fa ya help jamie:reallymad:reallymad:reallymad:reallymad:reallymad:reallymad:reallymad:reallymad
what do you mean less than 3 bar across two rotors?? did you just use a normal comp tester?
hi karl, yeh just standard compression tester, is this not right?
cheers

a comp tester for a piston engine will only give one value where with a rotary tester you will get a value for each face of the the rotor such as 7.1,7.3,7.2. To be honest i would expect a piston comp tester to hold at the highest value so 3 bar on each rotor is not good at all.
Hmm.. You say your boost gauge is just normal at idle? Does it sound the same or does it sound like a tractor?
davehg and karl, press the button on the comp tester in and watch the pulses. three pulses on each rotor. you dont need fancy gear for rough on the driveway diagnosis, especially when the comp is that low. sounded bad on idle like it had a miss fire and the revs would drop off every now and then. it was poor to start aswell. also the vacuum on idle wasnt great. it boosted fine but didnt pull at all. fuel pressure was fine, all vac lines connected. which immediately points the finger towards compression.
rolley said that when he removed the plugs one of them was quite light in colour and had little bits of spatter on \' like welding spatter\' . so seems to me like its leened out and detted and it needs a rebuild.
anyone who has standard exhaust and wheels for px with 4" turbo back tiger system and 18" split rims with exellent tyres, theres also 3 head up displays measuring boost, volts and mph and revs and an apexi poweer fc and commander up fa grabs.
i sent you a text message about the pfc today. but you didnt get back to me.
to be honest you can tell by removing a plug if the comp is any good, the needle will flick so fast you would never get a propper reading but is ok for an estimate only as in this case with comp that low. I dont recall ever hearing of one with comp in the 3s without a chipped tip..... :spank
im gonna pass on the pfc mate, but ill have the engine off you for spares.
just one question on the comp test. you did have the throttle fully open when you cranked the engine over didnt you? as that can affect the compression a lot.
did\'nt touch throttle at all mate just turned the key.
Take the valve out the comp tester, It will affect the reading. Should screw out.
keith.
do it again with the throttle open then mate, and as said instead of holding button remove valve on comptester.
will try that 2moro guys thanks:Hammer
how did the second comp test go?
Hello there, as I already have a pfc, any chance you can sell the commander on its own?
