Just checking if this is necessary if you go cat free! or can it just be left?
cheers
Title: help me choose what mods!!!
Post by: chrisJDM on March 11, 2008, 09:49:40 PM
it can just be left but its a pretty heavy pump so reduces a bit of weight from the engine bay and also frees a bit of space

yeah iv spied all that stuff, got a source in japan as well so will wait check the best prices.

thanks for the help, has cleared a few things up for me that i was unsure on.

just back down to the front mount vs v-mount debate and the advantages/disadvantages of both.....

to be honest on a twin turbo you wont get a massive gain from a v mount a front mount will do the job

fair play....i wsa begining to sway that way anyway, cost in mind i could get a lot more done faster that way.

Once you have done all those mods above you will basically have the same spec and mods as me, although at the weekend im going to pick up a single tubby :)

Post by: hammy on March 12, 2008, 03:41:58 PM
haha, a very relaxed...\'but at the weekend\' :D
 
very jealous indeed.
 
what power you running with those mods and the power fc mapped?
 
you putting the turbo on and running it with the same parts/intercooler etc?

i think it is somewhere around 400bhp @ flywheel running at 1 bar but ive never actually had it dyno\'d.  For now i will probably get it fitted with the mods i have and it should hopefully run around 1.0-1.1 bar with those mods, in future might have to uprate the fuel pump and possibly ignition.  Also i have water injection to fit, which is another good mod you might want to add to your list as your turbos will get very hot and water injection will cool them down a bit
