hi ive currently got a 2wd which im doing an engine rebuild on at present. Im looking for 400 and 400 only as im on a 205 block. So far its got standard mahle 0.5 oversize pocketed and dished pistons, lightened and balanced crank, rods, flywheel, its running a t34 with 360 normal bearing and .48 exhaust housing, ive got bd14 inlet and exhaust cams, isky double valvbe springs, group a head gascket, full mongoose exhaust, 500 intercooler, bailey breather. did have greys but got told they were hose pipes so sold them and opted for some siemens 660's. the head ive got has been nicely ported but is cracked in one of the chambers which im currently trying to get repaired, yeah i know but its a good head othet than that. ive been told that going to a bd10 exhaust cam would be a better option and also im a little unsure if these are the injectors i need? any other pointers to get 400 would be great. it made 378 before on the set up ive just explained with the greys and the orginal chip it had. we have full mapping facilities at my work so thats no issue, its just gettting the basics right, any help would be great. oh yeah its got a 3bar and is on standard L6 2wd saff management.
