RB20 AND rb25 similarities and differences BUILD

[autoeurotec]

ok so as i posted before in my other threads im building my rb20 hatch and have the sc61 now and buying the tial 44 and bov but....i cant find a fuel rail and injectors for rb20 and wanted to know if the rb25 fuel rail fits rb20 and if i can buy rb25 880cc injectors and them work on the 20????

also as far as a manifold goes i was gonna try to have someone weld o tial flange onto the stock cast mani but heard thats a hard metal to weld.unless someone knows where to get a rb20 manifold CHEAP for a s chassie.

it's not that its hard to weld, it's hard to keep it strong, the weld will heat up and cool down extremely fast and will crack after time. as for the fuel rails the odd thing is the rb20det is closer to the 26 then the 25, but i would not recomend interchanging the fuel rails since you can get the GReddy GTR Top Feed Fuel Rail 11.0 Dia for like 200 bucks. and you can get all the way up to 1000cc injectors from http://www.nengun.com/sard/injectors.
as for your manifold check this out. http://store.max-redline.com/servlet/-strse-445/Detail

The RB25's use side feed injectors that cost more than top feeds. Try RC injectors or Precision injectors, I run Sard topfeeds on mine. Cheap manifolds = looking on ebay for the SSauto stuff

Why do yo want to change the rail?? The stock rail should be enough to flow for your HP.
Do like the wrc cars and run a restrictor and a AVCR OR PROFEC E-01 or world electronic ebc
