ahh ok, would i have to buy anything else along with this to fit it to my car??
love turbo noobies, reminds me of a younger self
take the standard exhaust manifold and a t25 flange to a metal fabricator and get them to make you a manifold,probably about 100 quid, you can use 1.6 injectors or sr20 ones, downpipe can also be made at the fabricator, wont be hard for them to do that, you can get an intercooler of a vauxhall frontera from a scrap yard and various intercooler piping off other scrap yard cars, oil lines can be made at a somewhere like pirtek,they are nationwide company and are mobile, or a local pipe maker like i have local to me.....
im not sure if nissan ecu's can be socketed for tuning or not, you could use an FMU (FUEL MANAGEMENT UNIT) not the best like but basic and cheap way of managing the fuel, you probably wont be able to rag the car with this though as they dont deleiver enough fuel at high revs which makes the engine run lean and causes piston damage etc etc, seems to be a common complaint with fmu's
all in all you can probably turbo your car for less than £500, im in the process of boosting my civic and im nearly finished, ive spent £340 so far
hope this helps and good luck if you do go ahead, best person to assk is stani on here cos hes running good power with no engine management LOL
