If you want 280hp & dont have a big budget then a STi JDM short block & a good remap.

can you explain please both the budget and STi JDM short block please ?

JDM STi is a japanese import engine that will replace your old engine. Standard japanese engine are 276 bhp. Cost wise if you are on a tight budget this is the most cost effective. If you want a bit more and want to future proof yourself you can put a fully forged engine in as a replacement. This engine will be much stronger an if mapped properly will produce more power. Alan Jeffrey runs EngineTuner and produces a 2.1 stoker engine that has been producing some great results.

All down to how much you want to spend

cheap like the bird ideally, i no thats not guna happen. some one to take engine out then put back, once engine is done £200. Some one to recon the rb5 without parts £300. so say another 1500 for parts or up graded parts, or scrap to 215bhp rb5 lump altogether?
