how to get 500hp

[BlitzBoy]

depending who ports your plates, you can get full boost in the low 4k rpm range on a large turbo

very true, this is why i asked if he wants to have a rebuild with porting or gonna use his stock port engine.

We shall see what he wants to do engine wise as that will make a difference a little bit on turbos aswell

Just to add to the discussion on achieving 330bhp, my FD did just that with 3" downpipe, decat and cat back, a pfc, a greddy SMIC and a high flow filter element in the stock box. Thas was mapped by Pip and made it at 0.8bar with the injectors being the restricting factor. Everything else was standard. Therefore if you add a boost controller, uprate the IC then get a map you should be about there imo.

Yep me too,well just below at 0.9bar on stock ports/injectors/fuel pump/twins. Also limited by inj duty but having since changing my fuel filter those figures have dropped from circa 94% to 89%.

i be hoping to get 333bhp or at the fly what ever gets displayed on a dyno and it will be stock engine at the moe (untill it goes then rebuild with street porting done) and stock twins so if i get 4x850cc and uprated fuel pump a fmic and a hks downpipe to go with my de-cat and blitz exhust and ive got twin apexi filters stock rad and get it mapped with 0.8/0.9 bar boost.

well looking at that, you will have enough fuel, the fmic will keep the temps down so you should be good to go, how much power you get depends maybe on which tuner you go to

ive new to this and i just found out that there are 2 850cc in as stock so i mite as well get 2 1680cc.

If you get 1680\'s, you\'ll need a new top feed secondary fuel rail - get one of Kev\'s from //www.billetbitz.co.uk - they are works of art.
Bear in mind that if you go that way, you\'ll also need to much about with the fuel lines as well, and the easiest solution is an aftermarket fuel pressure regulator. Realisticaly, you\'re looking at £400 or so to do 1680\'s properly.
Cheaper alternative is to fit 850#s in the stock 550 location - costs about £10-£20 in machining, and £30-£50 for a set of SH injectors.
However, as with any SH injectors, it\'s advisable to get them cleaned and flow tested before fitting - Scholar Engines in Suffolk can do this for you for about £8 per unit or so.
