E30-ls1

[WillisE30]

This is going to make my S52 swap feel underpowered and weak. Very nice work and writeups. I look forward to seeing it in person someday.

[A.LACK]

We need updates!

^^ what he said...

[Brinkley]

wow. im very impressed. i hope my project will look half as professional when im done.

[steinkek]

Just read the whole thread!!! WOW this is a crazy project.

Where are the updates?

[devonjordan]

REad this earlier today, when do we get to see the vid of that car tearing it up?!?!?!?

[Shoomakan]

Will your dad adopt me? I want my dad to help with my E30.. I had a V8 240SX previously... You're gonna LOVE the low down power you're gonna have... Are you sure the mixed headers won't create bad harmonic flow?

I have been busy running down the last (almost) parts we need; PS hoses and fittings (hydraulic supply shop has JIC 3/8 (like AN6) fittings for the PS hoses for about $3.00 ea)

Had to drop the radiator off to have the RH end cap swapped since the outlet was right in front of the A/C pulley; new cap for about $75.00

To those who thought that our engine mounts looked weak:

Here is the FEA loaded with 3G's vertically and horizontally and it only used 1/3 the ultimate strength (i.e. it could handle up to a 9G bump)



-Garret

You failed to show the strength of the Factory rubber motor mount loaded off center being pulled straight up. The original design is centered and pulled at almost a 90 degree angel. The weak point is the stock rubber mount not the metal one you built.

Keep in mind that the rubber mount "does not know" how the load gets to it. The cranked arm of the mount sees bending and torsion stress, but the rubber mount itself sees nothing but vertial loads, and some braking loads.

If the mount weldment was very "springy", then the rubber mount might see some torque on it around the Z-Axis (cross-car). As it is, the mount weldment deflects very little (<.005"). See our pics of the loads on the mounts: 260lbs on each engine mount, 83lbs on the tranny mount. What you see in the FEA is 3x the static loads: 750lbs vertical combined with 250lbs fwd-aft. The rubber mounts we used are BMW E34 / M60; the M60 engine package is heavier than the LS1.

Garret & Steve almost done with E30-LS1; just got to run down brake & PS fittings, etc.

cant wait for video of it finsihed!

E30-1UZ; just got to run down brake & PS fittings, etc.

Same as me to! oh and the link computer tune

Awesome work! I'm trying to finish my fourth year of a Mech Eng degree down here in Pasadena this June. I chose the turbo route for my car.

That brake booster is sick! I would love to see the drawings if you don't mind. What program did you use for the stress/load analysis on the engine mount? Is it part of a CAD program's toolbox? I'm mainly a SolidWorks guy but should probably get around to learning some of the more industry standard pieces.

We used Catia V5 for the CAD work (we use it on our 787 work) and Algor for FEA.

Catia FTW, that's what we use at OSU for all of our SAE Formula and Baja stuff. You work at Boeing? I have a few friends that just finished up internships there working on 787 stuff.

[garretvs]

Our company (I work there & Garret has done summer interns there (he designed some equipment for the 787 program)) supplies assembly equipment for the aerospace industry. We have worked on AirBus, Boeing, Lockheed etc programs. Our 787 work included all of the equipment necessary to assemble all of the major sections of the airplane: 6 fuselage sections, join wing to body, install empennage.
