Im looking to get around 275rwhp - 300rwhp. I need to know the basics for getting more power out of my redtop. I have a basically stock sr20det with nice front mount intercooler and a Walbro 255 fuel pump. Thats about it. I want to know:
1. I know i need a better turbo for more power, so Im thinking GT2871R.
2. With a new turbo, how much power can I make until the stock injectors are maxed out?
3. I have a KA MAF, what should that be replaced with and at what power level is that necessary?
4. What is the "best"(read cheapest way that works good) thing to control the bigger injectors?
5. Do people have success with piggybacks on the sr20? Like an E-manage, SMT7, etc...?
Any other comments to help me know what I need to get that kind of power. Thanks. Also, if there is already a badass writeup that already goes over all this, just please post the link. Thank you. |
1. a 2871r is a nice turbo...they can usually reach around 350whp (thats on average, i've seen 400whp on the larger trim). the .64 trim will give you more mid range. .86 a little more on the high end. for the power you're looking to get, you may want to look into a s15 spec r t28, those are fine for 300whp and a little less expensive.
2. the stock 370's are good for around 240~250whp, anything above that, and i'd upgrade to a set of 550's
3.the stock maf (sohc same as the sr) is maxed out between 250-270 so i wouldnt take it above that.
4. the best and most cost effective way to control the fuel system (IMO) is an enthalpy system. a good setup with a warrenty.
5.a piggypack system isnt too bad, just depends on the tuner. the safc's are ok, but def. not the best. and people are getting better results with the emanage ultimate than with the older version of the emanage.
keep in mind, these are just my opinions....everyone here is going to have a different one.
good luck with you're search.
