im running 350bhp with an 18g 440cc injectors a hybrid FMIC and a nice simtek ecu, i have just got me hands on some power enterprise 550cc injectors and am thinking before fitting them and remapping is it wort getting some headers as well as some people say it will make it spoil up slower and not be worth it, what your thoughts on this oh ps mine is a 2 liter lump

 

i put a vf35 on mine with sports cat fuel pump the usual mapped it and made hell of a diffrence so i then got some 4 to 1 headers and mapped it again and the mapper said it was very small ammount laggier (i dont notice it) but my god at the top end totaly diffrent power all the way no drop i can feel power is there pulling, brilliant...
had a new engine put in and left ome headers on and went for a spin and it was good but no were near the same, engine ok put 4 to 1 headers on and felt totaly diffrent again powers right up but i dont have a red line limiter and it just pulls till gear change

 

I had Harveys ported headers on my type r, and they made a hell of a difference. I suggest speaking to him with your aims and he'll tell you what you need.

 

yes thats another option which i might do with my ome ones and compare the diffrence, as i miss the rummble. mine still has it just not as loud

 

humm i was going to buy some of them jap speed headers but after reading a few posts abut them im not so sure i wonder how much this Harvey chap does it for and one got a way i can get in touch with him

 

You can pm him on here mate.
