My car currently has:

-ETS intake
-ETS UICP
-ETS o2 dump
-ETS test pipe
-ETS V2 regular
-Grimspeed EBC

Made 312/338 on a mustang dyno and 91 pump. I know mustangs are not the best for accuracy.

I was hoping for a bit more, somewhere in the 350 range (want to get semi close to my uncle’s RX7), but I am 100% deadset on not having to replace any engine parts or run E85. Saw the headache my brother had to deal with on his E46 M3, I don’t have the time or the mechanical knowledge to deal with that.

Tracking wise, maybe once every 2-3 months.

So is there anything else I should be considering or am I at my limit without an engine rebuild/E85? Totally wouldn't mind if this was the end of my modding journey on the X if it meant it'd be reliable.

 

You are at the new turbo point I think which adds injectors, fuel pump, and downpipe if you want it.

 

You might squeeze out another 10-20hp with a FMIC but to hit that 350 it's time for turbo/injectors/fuel pump, like Napalm said.

 

I would add that FMIC and see how much that adds. I have buddies with Stock blocks making 400+ on E85 so the motor is still good Past your 350 for sure. However, the peeps above are correct. time to put some money into her. Only thing I would add to their list is head studs. you can check out this kid on yourtube; 370zforme he claims to be making 668AWHP on stock block but with the upgrades listed in the above posts. 5150 tunes out in Cali (he posts a number of videos on the build about a year ago)

 

Thanks for all the replies.

I was already thinking about the FMIC, a little irritated I already bought the UICP by itself though.

Doubt I'll go with more power if it requires that much modification, I'm relatively happy with how it is now.


One last thing, my coworker has an unopened AMS intake he never installed. Only found it because he's moving. He's willing to sell it to me for $250. Is it worth trying to get rid of my 3 week old ETS intake for cheap + retune costs to run the AMS? I originally wanted the AMS but I already chose an ETS exhaust so I just figured I'd have everything ship together at once.

 

Not worth it. The difference would be impossible to gauge imo.

 

Talk him down to $200, sell for $300 and partially fund that FMIC

 

ETS and AMS use the same size tubing to make their intakes. people make well over 600hp with both. For your numbers its not worth it. also dont be angry about having the UICP already.... that needed to be changed the day you got the car. The stock ones can expand a full inch in diameter under stock peak boost...

 

I got 348hp/346tq on 91 with...

intake
uicp
licp
3.5 FMIC
HFC
Catback
3 port
1000cc
AEM fuel pump

394hp/376tq on e85.

Get a front mount



BTW... I use a depo FMIC... It is $330 and the quality is really good

 

I managed to run 348/335 on 93


aem intake
cobb ebcs
ets catless midpipe
ams catback
ID1000 injectors
DW300c pump


time for the OP to mess with the fuel system I think.

 

Anything else you should be getting? Well, yes. You indicate you're going to track the car periodically? Then it's time to concentrate on the suspension setup. I promise that, on the track you will care less about making more power and more about your handling.
