Hey guys, just bought my first 180sx so all new to the sr20det. Was wondering if anyone could give me some advice on increasing the power without breaking the bank! I'd love it if i could get near the 300rwhp mark. It already has, apexi exhaust system with de-cat,hks induction kit,front mount intercooler,blitz t-timer! Any help would be appreciated.

Welcome! If you're running the stock T25G turbo, then 300hp won't happen. 220hp is around the limit, and there really isn't a genuinely cheap way to net much more power on a 180sx; the turbo just runs out of puff too fast so you have to replace it.

 

Irrespective of which turbo you choose, if chasing more power you'll have to invest in injectors (550cc will support 300hp), fuel pump (Walbro 255 or Bosch 040), ECU and tune (Nistune daughterboard is a common choice here, but it really depends on what the tuners in your area support) and an AFM if chasing more than 200kw (Z32 is the most common upgrade).

 

If you want to keep it on a budget, get an S14/S15 T28 and shoot for around 250hp, or for more power on a budget, a lot of guys here get the Kinugawa turbos off eBay (chinese turbo of reasonable quality, or something along the lines of that). Cams would help you extract a better top-end power figure, but for the best response and price-point, just use the stock cams, or SR20DE cams for a subtle boost in top-end flow.

 

When increasing the power, you'll also want to consider engine mounts, clutch to hold the power, slave cylinder to match the clutch (results vary, and the slave can help with increased pedal weight), subframe mounts/collars because yours will likely be 15-20 years old and will axle-tramp all over the place and radiator, as the stock one struggles on factory boost. Replacing thermostat and as many water hoses and vacuum lines as you can would also be sensible, to avoid killing the turbo or engine due to old hoses splitting with increased heat.

Sweet. Just remember that whilst some changes don't require a tune (fuel pump) and some changes you can putt around town without much issue (oem T28 running factory boost), others definitely require a tune (injectors, AFM).

Every fibreglass panel is of lower quality and visual fit/finish than the oem metal and chassis. If you buy genuine Jap panels you're likely to have fewer issues with fitment, but they still aren't on the same level as oem.

 

You may wish to consider checking out the wheel specs in the Offset Perfection thread (http://www.nissansil...l=&fromsearch=1), choosing wheels of a similar size and offset, then just getting a roll and flare to suit. Widebody looks horrible without wheels that fill the guards out properly, and without A LOT of panel work the terrible fit and finish of widebody kits just looks bad. Even in the case of Xris's 180sx, who is a professional and put a fair amount of effort put into getting his kit right, it's clear that it doesn't line up as well as oem.

 

It should also be mentioned that if you still with stock body + roll + flare, then you'll have a greater selection of decent wheels at decent prices, it will be far less work and be far more legal.
