Is250-v12



Hi Guys.........here goes - I have a 2007 IS250 Auto. Fitting a Toyota 5lt V12 in to her. keeping stock tranny.

This is the full plan, some of which is already done:



THE BODY

oem grey colour but with some carbon vinyl stripes.

carbon Di-noc vinyl roof wrap.

rear window spoiler

rear trunk ducktail spoiler

rear bumper diffuser

custom wide body - front and rear fender extended out by 2 inches.

custom vent in hood

custom front bumper with 2 large vents for radiators

Eibach prokit springs all round

19 x 11/9.5 rims........please advise of correct offset?

Porshe Cayenne Turbo brake calipers all-round

custom made floating discs(rotors) all round. front 360mm rear 345mm

EBC red stuff pads all round

Custom camber kit all round



THE DRIVETRAIN



oem diff ( Y55B) with 3.9 final drive ....need to find 3.7 MT final drive soon?

lsd soon.... what are my options?

oem auto tranny (A960E)

SSP torque convertor and oil cooler

TRANSGO quickshift kit.....any reviews?

good oil ...........any suggestions?

shifting the tranny as far back as possible.

custom Prop/drive shaft



THE POWERHOUSE!



Toyota 1GZFE 5lt V12 - sourced from Japan Yahoo Auction

custom rear sump

custom exhaust manifolds thermal coated

dual 3inch exhausts with 2 silences

custom inlet manifold

Harrop/Eaton HTV 2300 Supercharger

custom rods and pistons...Eagle, CP

custom head gaskets

custom cams by Kelford

750cc injectors x 12

2 x 255lt Warlboro fuel pumps

custom dual radiators

custom engine to tranny adapter

AEM water/meth kit



ELECTRONICS



stock ecu

stock harness

standalone ecu for engine....36-1 crank trigger just like stock engine

Camcon controller for cam advance

because of all the electronics being linked to everything, I have to use oem ecu. but it won't actually control the engine.

I will just use all the oem engine sensors and give the ecu the signals it wants. sure there will be engine lights, but won't affect engine control because of standalone unit.



PROJECTED OUTCOME



an exhaust note of note

a diff that will shatter to pieces

a tranny that will slip it's clutches

a good handling vehicle

enough torque to pull the moon out of orbit ..about 850nm

enough HP ( sorry enough is never enough!) ....about 800hp

max boost level... about 24psi

fuel consumption......... the worst possible!

Still..........a very happy chappy!



at the moment I am busy with the brakes, springs, bodywork, tranny and diff. supercharger is sitting on shelf waiting!

the engine will be landing in 3 weeks. then comes the marriage of engine and tranny( and possibly the end to my actual marriage at home!)

stock engine has been removed already.

will be running the v12 engine stock for a test first @ 6psi



this is my first time I ever joined a forum, so please excuse anything wrong.

part of the reason I am sharing my build is to gain some knowledge about certain issues I may have ( sorry, will have)

right now I need urgent advise about wheels.

I must use 305 on the rear. so a 11j rear rim sounds the way to go. I want to purchase the wheels but I am stuck with the correct offset. I will be rolling or extending the fenders, but that is not my concern. I need to make sure the inners don't scrape. I cannot take the car to wheels center so I need to make sure of offset please.
