couple Q's on a turbo set-up DOM 3
i've chosen the turbo i'm going to go with
i'm going with the dom 3 what i'm wondering is...what else is nessecary to compliment this turbo... i know injectors...but sizing...? i want to be safe but have room to work with on these injectors... do i need a new inlet or will the stocker hold? do i need a bigger maf or will i be fine with my SPT intake... do i need an aftermarket boost controller? if someone can ethier link to me a list or give me some guidance i'd be more then happy Thanks for your help guys...i wanna get this rolling...

At minimum, you will need the following:
3" Turbo back exhaust (catless or high flow catted) 740cc+ injectors (I used the DW 860cc injectors) A high flow fuel pump (Walbro 255lph here) A turbo inlet (I suggest the Perrin) A big MAF intake (Perrin, COBB 70MM, APS 70MM CAI, etc) A boost control solenoid like the Perrin or GM (I went with an AVC-R) A large top mount IC (I went with a large APS Front Mount) I would also HIGHLY suggest the following: A new clutch TGV Deletes Fuel Rails An EWG Setup |

Fuel rails and an EWG is not needed, unless you will be pushing past 23psi, which is bad for the stock motor anyways.

just a couple of Qs.
any trouble with the perrin pulley? curious,because i was told that maybe with big power,it could sometimes cause car to stall after fast accelleration,and then decelleration. why the boost controller? other than that,nice list |

BC because stock boost controller really sucks (i think they changed it so your 06 i believe has the one from previous years which is ok) the problem is on other years you can spike your boost at low rpm and then ride it out on the 07 you have to wait for it to come- might want to ask someone who REALLY knows how to tune the 07's because every tuner will tell u they can but they can explain it better as i am just passing on what i remember from conversations

and the light weight crank- you can tune your map to work with the lighter pulley and also increase idle which will keep this from happening but yea before when i first put it on every so often for the 3 or so weeks i had it b4 tune it would stall if i floored it to redline and put it straight into neutral (same thing will happen with light weight flywheel as these are the only 2 external weights on the crank so whichever you lighten or both have the same effect) but i love the benefits it accelerates and decellerates throught the rpms much quick (less rotational mass/inertia) and because it drops the rpms quicker you can get quicker smoother shifts IMO

If you are already on STG2, this is what you need, and what I'd get if I'd go Domtree.
DOM3 (2.4" inlet 8cm2) DW740cc injectors Walbro fuel pump APS top mount or FM (your choice, to hack the bumper or not) APS Inlet APS 65mm intake Grimmspeed TGV deletes Prodrive BCS |
