Recommended Posts

Hey Guys:

 

It's official this is the Direction we intend to take for the New Z Project! Need input and Help for sure!

 

SPECS:

Engine: will be the Chevy Vortec 4200, running ITB's in a N/A mode to start!

Trans: Supra R154 mainly because I have one in the shop, has some bad Syncros, but is buildable. Need input there for sure or someone want to Build it for me.

Rear end: is a R200.

 

Let the input begin!

We have not measured it as of yet, some Research on it looks as if the Intake Manifold was one of the biggest issues, so going with ITB's from Jump Street will negate part of that!

 

The largest obstical I see is the X-Member, and Front Sump vs rear sump issue!!

 

Our BMW Project Car has to be completed first, so we are 30 to 45 days from dropping a motor into the chassis for sure, but if any of you guys have these motors in a New Vehicle PLEASE post some Actual Dimensions!

 

Thanks!

Yes I agree! The oil pan-xmember will be the biggest issue I'm afraid!

 

Force fed? That will be a natural progression I'm sure we will head with the Project!

 

I have a Good Friend that's been living in China the last 3 years BUILDING EFi software and Hardware for a Company there! He's ready to come home and bring his Technology with him! They currently have 1 ECU that runs 2 seperate Fuel systems! Currently running STRAIGHT Ethanol, and straight Gasoline in each system! The ECU can switch between the 2 different fuels where you can't tell it, and has met the Euro4 Emission drive Cycle tests with the ECU! It's pretty impressive feat! It has some draw backs like lack of Coil Drivers, but is being redesigned to work on V8, sequential Fuel and Spark, so it will be neat to play with!

 

Work on the BMW is Progressing today, so hopefully get it done and out of the way to move Forward!

Hey Guys!

 

I have been trying to get on that inliners board and it is DOWN! :(

 

Some thing's I have found out:

1. New I4 Canyon Bell Housing is $552.66 not counting and Discount #8904-8229

2. New I4 Flywheel is $247.42 #8906-0406 No discounts. Called local GM Parts desk for those numbers!

 

From what I have seen the 4L60E is the number "1" Piss, moan, and Groan! So that would suggest the i6 Torque is eating those transmissions to me!

 

DAN?????????????????????????? Where ae ya here? Hahaha!

Kevin, the flywheel from both the 4 and 5 cyl versions of this motor will not work with the LL8 (4.2 liter). The bolt pattern on the crank is different I believe. You will need a manual bellhousing from either of those motors and then it can be mated up to a Toyota R154 5-speed from a MKIII Turbo Supra. The flywheel and related parts are the real holdup IMO.

Well from what I can gather, the i5 is not offered in Manual either? Especially the 3.7ltr i5's.

 

The number 1 complaint on the i5 and i6's is transmission problems, and they are all automatic issues too!

 

Here's a comparison of the i4 Manual and i6 Auto crank patterns! They both have 8 bolts, but the i6 looks to have a large machined opening for a pilot bearing to me and the bolt circle looks larger as well?
