I'm getting a simtec ecu fitted later this month and I'm wondering what is the best thing to do induction wise?
I currently run a hks panel filter with a standard air box, can I keep this when the MAF is removed or should I go down the route of a cone filter with heat shield?
If I keep the panel filter, do I need to replace the pipework where the maf sensor sits and if so , what with?
Car is a my99 rb5 with td05 16g, should be running about 300/300 (i think) after the simtec is fitted.
Anyone already running a simtec -what have you done? Pics most welcome
Cheers

 

You can keep your panel filter, just unplug the maf sensor

 

as above no point spending as the maf is just atube with alittle sensor dangaling inside so wouldnt act as arestriction

 

...although I only unplugged mine because of going induction with the FMIC...keep the panel filter and using the maf as a connector is fine IMHO...

 

As above, your 16g will make a max of 340-350bhp, which is also about the limit of the std panel filter/induction tract and MAF tube. So just disconnect the MAF connector and leave it at that.

If however you decide to fit a bigger turbo, injectors etc, for more bhp, then you'll really need to junk all of the stuff mentioned, and replace with a simple tuned trumpet/large K&N combo, prior to mapping...

 

Cheers for the quick replies, the thing is, I don't want to leave the maf sensor in there as it's almost new, I want to remove it and keep it safe incase I ever revert everything back to standard ( or flog it to recoup some of the cost of the simtec ) I'm thinking I'll have a hole in the pipe work where the maf was removed from? will i not need to blank it with something

 

Actually, forget the last question, I'll just swap my good maf with a broken one I have lying around somewhere.

 

Yeah you could replace the decent MAF tube with an old non-working one.... but I'd simply be inclined to remove the OEM filter/inlet trunking and go for the large K&N/trumpet and get mapped.

 

Stick with the OE airbox until you are ready to go above 350 bhp. Personally I would not use HKS filter. Use either K+N or OE Panel. Anything you can do to smooth out air flow is good so removing the MAF sensor from the body and filling in the indent with filler, substituting a silicon pipe or similar is a good move but really is fine tuning.
