I was an active member quite a while back. I left because the old place seemed stodgy, but see that some changes have been made so I'll post a few things and see how it goes.
I'm a ford guy, but I hate the sameness that is typical w/ just about every build you see typically featured. I simply would not/could not condone yet another windsor V8 build up.
So,....in a real desperate attempt to stay "true blue," I decided to build up my first I6. I've spent way more money than what could be construed as rational, and have went so far off the deep end with this thing I'm hoping and praying that I havent created some future reliability nightmare that'll make me regret my decision.
Here is a bullet point list of what I've done:
* 250 block partially filled, with all 6 holes sleeved w/ .093 wall ductile iron sleeves, overbored +.020 final bore size 3.700.Deck widened w/ 1/4" bar stock to accommodate X flow head. Driver side cut open to allow access to "re-link" together BBF roller lifters, 3/8" cover plate fabricated to cover access holes.
* Rotating assy includes 2618 alloy Racetec forged pistons, Stock rods prepped for full floating pins. ARP bolts added. Stock crank, modified to accept SBF harmonic balancer.
* Camshaft is Aussie pattern solid roller 558/530 w/ 230/225 actual duration at .050 ground by Tighe in Australia.
* Competition cams Extreme series solid roller lifters to fit BBF application.
* SBF billet double roller timing chain set custom drilled w/ 2 1/4" dowel pins. 56 tooth double roller timing chain sourced through 3rd party supplier to fit some Toyota engine.
*Head is aluminum Aussie Xflow. Self ported with stainless 1.88 BBC exhaust valves cut down, now serving as intake valves. SBC 1.5 exhaust valves. BBC beehive valve springs (installed at 1.900, rated to 400lbs open pressure). Crower BBC 1.75 ratio "altered ratio" roller rockers.
* Intake is made of 14ga. mild steel exhaust bends, patterned after BMW M3 aftermarket unit. drilled to accept 42lb/hr. high imp injectors.
*Exhaust is made from .140 wall mild steel "steam pipe" els.
*Borg Warner SX300X 60mm twin scroll turbo charger.
* EDIS-6 ignition
*MSII/V3.0 kit built ECU
*External electric water pump.
* External belt driven oil pump.
* Custom made front drive system.
That about sums it up. It has been started, and it runs. I am presently waiting on a boost mod kit from DIY so I can modify the ECU to provide electronic boost control, but other than that,..this frankenstein combo runs.
I'm doing this here to serve as a sounding board for questions and answers for any of the things I've done for others here considering the limited options we have with this engine when it comes to modifications so feel free to ask how/what I did to get here if you are interested. Enjoy.
