question

[kamikazestorm420]

if i get a s13 sr20 and have the following mods:

-downpipe-exhaust-testpipe-intake

would i need to upgrade the fuel pump, filter, or the maf?

Fuel Pump - good idea since you'll most likely be looking at needing to upgrade it in the future, it's not too expensive and good insurance IMO.

Filter - really cheap and gives HP, no reason not to go with some cheap K&N style filter. Heck, I think I got a cheap filter and MAFS adapter from Heavy-Throttle for ~$15. You can get them even cheaper on ebay I think.

MAF - Nope, stock MAF/Injectors are good for ~250ish rwhp. That's about 14psi on the stock T25 with a FMIC and bolt-ons, so you'd be a bit shy of that.

I definately agree on the fuel pump. Your old one will probably not be up to the task of supplying an SR and it would be a shame to lose a 2k motor over a 100 dollarr pump.

Also, dont get a testpipe. Get a high flow cat and save the environment a little. The gains you see will not be noticable.

Those mods would probably net you around 250whp, but remember, the FMIC is NOT going to give you power, it will allow you to run higher boost levels.

1 bar is possible on a T25, but thats about its max. The MAF should be good until you go for a turbo upgrade.
