Runs the engine good or not?
 
HI,

I will buy a RX-7 FD again.
But i will ask you, about the engine.
Is the engine still good or not?

I have get a video from the start and run from the engine.
Here on youtube


Specs from the engine:
26t km (16t miles)
August 2011 compression test:
front: 6.9bar(690 kPa), 6.7bar(670 kPa), 6.7bar(670 kPa) bei 257 U/min
rear: 7.2bar(720 kPa), 6.9bar(690 kPa), 7.2bar(720 kPa) bei 256 U/min
Is that ok or not?

RE-Worx Uk has make the ECU tuning
It has 261 KW(355 PS)(350 HP) with the twins.

another Mods:
street ported
850cc injection nozzle
bigger fuel pump
3" Downpipe without a Cat and a KAKIMOTO Exhaust
Oil Catch Tank
AEM IC
bigger Waterradiator
Greddy Pulleys
AST removed
Secondary Air Pump removed
Apexi Power FC with controller


when the rpm fall down in the video, is that because the secondary air pump are removed?
Sry for my bad english.

Thanks for all.

thank you.
And the compression is ok? or is it a bit low?

The compression is not great, but it's not horrible. It's basically around 100 PSI . If it was below 90 PSI, I'd say you'd need to budget for a rebuild.

350whp from RE:worx's dyno are VERY strong power numbers! If I remember correctly I was only making about 340whp on their dyno when I had BNR Stage 3 twins at about 1.1-1.2bar.
