The Haves:

The Engine: 20B Serial # D659, No compression Rear Rotor (Remember this!!!)

The Chassis: 87 TII, black on Grey, 120,000 miles.



The Have-nots:

ECU: Microtech LTX-12 or Haltech E-11 (If they ever get off their ass!)

Cooling: V-Mounts, custom by Griffin

Mounts:See Plan

Turbo: Undecided

Manifold: Undecided

Clutch: It's sooooo nice having a Major Clutch Manufacturer up the road!!! https://www.nopistons.com/forums/pub...IR#>/smile.png , you'll see





The start of the metamorphisis:

1. Strip 20B down to KEG

2. Mount Transission

3. Gut the TII

4. Start mock-up.



More to come, I plan on starting a Web-log..

The Current Dilemma:



Mounting Location of the 20B:

A. Use Stock location with K2RD or FC3S.org mounts

Pros: Easy/inexpensive

Cons: 1. Must re-engineer Sway bar

2. Cooling/Intercooler Mounting Room is Dimensished/compromised

3. Changes in Balance of car must be accounted for



B. Move engine Back ~ 160mm

PROS: 1. Maintain Balance of Car

2. More Room for Cooling/Intercooler



CONS: 1. Requires Firewall Move/Re-engineering

2. Engine Mounts must be designed/built

3. Possibility of shittey access to rear rotor

i looked at my car and the reason i cant move my motor back is because the oil pan goes around the steering rack. i wonder if building/modifying the subframe would work better? if you wanna blog here i can sticky this, and you can thread race jeff https://www.nopistons.com/forums/pub...#>/biggrin.png

Yeah, there you go. https://www.nopistons.com/forums/pub...IR#>/smile.png



You could try moving the engine back, but you'd need some sort of modified oil pickup tube to fit around the crossmember. Custom pan too.

I have plenty of X-members to hack-n-weld, I'll examine the possibilities!



I have an idea brewing, time for the Sketchpad!!! https://www.nopistons.com/forums/pub...IR#>/smile.png

oh so i had an idea last night for what to do. put a 1st gen front cover on the 20b, and use the 1st gen style front mounts to put the front cover near where stock is. then you can build something where you would find that undercar strut bar to support the stock 20b mounts?

That sounds like it would make the handling better than stick.

if that makes sense its the way to move it back without huge custom work.

oh and btw there was an fc with a vmount at seven stock, he tilted the radiator back and then had the old school greddy horizontal between the radiator and the hood latch.
