When I purchased my FD it ran fine but it developed a lack of power after about a week. I've had the engine and turbos rebuilt due to other problems. The car runs fine below about 4000 rpm but the power just dies after that. Anyone have any idea what the problem could be?

Thanks!

 

Looks like you're losing some boost after the transistion.

 

Yeah, it looks like the second turbo isn't coming in correctly or at all. It seams like the first turbo is working fine.

Can someone recommend me a good manual for the rx7, then I can have a look and see check the solenoids etc.

Prespool of #2 turbo is too late or not at all when it comes on line. The opposite is a large spike at transistion.

 

Thanks, this was the sort of info I was after. I will go through this but it will take me a week or 2 cause I can only really work on it on the weekends. I'll post the results of what I find.

 

you need to invest in a quality boost gauge my man.

 

Can you recommend one?

BTW, the original pic won't work anymore, here it is again

 

Autometer will do you right, pettit has a nice gauge kit

 

Spending lots of $$ on an expensive boost guage isn't worth it. Just get an Autometer or something.

Check out the RX7 Store. I've had excellent service from them.

yea i returned my autometer 3 times because it would never go back to zero always stayed at 1 or 2psi whilke the car was off.... i bought a greddy unit.... Always back to zero plus the lighting is better.

 

Holy ****, this is a FD? The peak power is only 148.8hp, you definitely don't have the second turbo. Check all your prespool and turbo control solenoids, lines and the actuators.

 

Its reading in KW. The conversion is 1 kilowatt = 1.340483 horsepower.

Edit: Opps your right, you allready did the conversion...sorry my mistake.
