Yea, you read it right! My friend Kevin back in Ohio informed me recently that a member of his StarQuest forum has aquired an ORIGINAL HKS DOHC head designed for the G54 SOHC engine...the intial investment to get the ball rolling is $12,000 for R&D. The first run will yeild 20 units, @ ~$2000 each. each run thereafter will cost less. the intiial investors will also see a price break as well as profit sharing from non-intial investors (customers).

this Head will be BETTER than the original HK$ version, as it will be cut from a solid piece of Billet aluminum, CNC'd design. There are SS valves already available for it, the Cams are already able to be produced, the hardware will be the same, only twice as much as before. And, cam gears are the same as stock... you just need a 2nd one. an appropriate length timing chain will be available. You can use all the stock gaskets, sheet metal valve covers will be produced. the seats are already installed and come with a 3angle valve job. and itll be threaded for NGK plugs.

Only 40% of the design of the NEW head will be based off the original HK$ design, so its small enough to be considered an ORIGINAL design and have its own Patent number. the Original HK$ version was originally designed for a G54/G52 NA hybrid motor which had a 2.3L Diesel crank in it, which were used in the IMSA/GTU race classes... same series as the NA FC3S :)

OH, and this new head will yeild a projected 18% increase in VE, all else remaining stock... including boost level on the 12A turbo.

anyone considering really modding a starquest should really look into this, the twin cam head would basically make 4G63 swapping obsolete, as the motor would retain its torquey traits, and recieve such a large increase in the overall volumetric efficiency of the motor..

i will be purchasing this head asap for my starion.... at the same time i will rebuild my bottom end so its super sick instead of just sick.... the 4g63 swap in a starquest is alot of fabrication anyways

actually, buschur has a set of mounts that he produces requierd to swap in a G63 motor into the StarQuest... the only problem is finding a Euro/Oz spec RWD G63 tranny to bolt in... :o My friend Kevin was stationed in London w/ the Airforce last fall, he went to some races and they were running starions over there. They have 4g63-equipped Starions over there, he was trying to find a few RWD trannies for us to send back... but no luck. :(

anywho... i would so love to invest in this project... except im broke... i want to make a difference!
