78 riviera suby conversion

alaskadan · Posted: Sun Oct 04, 2015 7:27 pm Post subject: 78 riviera suby conversion

Hey there i will be starting a 2.2 suby into a 78 riviera conversion soon. I will use this thread to document and ask questions along the way. Right now im getting the plan ironed out. Been reading alot . Ive seen posts about regearing a 4 speed trans with taller 3rd and 4th gears. What about an auto trans? The van has the stock auto trans in it. Im not sure exactly what it is as i have not crawled under the van yet.

I would strongly suggest that the 2.2 is from an OBD2 car. otherwise, diagnostics is a bitch without the SSM

I believe if you want to keep the auto transmission you can, and will need to use the RMW adapted plate (for auto).

Dan - what's your plan for the radiator set up?

A watercooled Bus project? I'm in. Very Happy

On a related note, I think it is time for "engine conversions" or similar to have their own gallery space.

OBD2, check. Radiator will go underneath between framrails. Custom cowling/scoop. I think Small Car has a mounting solution too. Im running their set up in my syncro with a 2.5 suby. So will the auto trans want to be re geared?

Sounds like you know what you are doing, and you aren't a fan of sleep. Both qualities that will come in handy in this build. Sorry I don't know anything about the autos; I'm going Subarugears. Maybe try one of the VW-Subaru swap Facebook pages to find out about the gearing. Someone on there must have done it.

Ha ha sleep? Theres no time for that. Laying in bed is when i go through dry runs building things in my head a hundred times Smile

. So a question regarding subaru gears, as i havent delved into that realm just yet. What do you do about the axles? Specifically the inner cv/flange bolting to a suby?

Ok so i lm looking for a slider door for the 78 to save labor straightening out the original. I went and looked at a parts van with a good door. Junkyard owner doesnt know what year it is and i want to varify what it is. Its a later bay , rectangular tail lights , front bumper is not stock so no help there, little rusty on various markers for bays.

Confusing part right now, the vin tag on dash is 2282111930. After searching and using two different vin id sites both came up saying incorrect vin..?

And using the technical section here this number exceeds the number starting in 79. Is it as simple that this is a mid 79 pruduced van? In which case the slider door would fit a 78 with no issues?

As an "easy fit" rule, if the bus has a gas flap/fuel filler door, the sliders will interchange nicely with others like it. If the buses have a gas cap flush with the outside body panel, the sliders will interchange nicely with others like it. Your '78 has the gas cap flush with the body, so look for a donor that doesn't have a fuel filler door flap.

The sheet metal build is the same for all, but the lock and latch mechanisms are different.

Thank you. Ok so when i looked in the technical section at the vin decoder what did i miss. I guess i didnt see anything regarding the first 4 digits.

Ok been reading and searching and have a couple questions. The riviera is an auto so that means adapter plate because the bell housing isn't removable correct me if I'm wrong.

Throttle body reverser, cant use it on a 2001 2.2 of the idle speed control valve. Read that on the RJES site. Thus im going to have to flip the intake manifold.

Problem there is alternator and ac. No big deal making bracket for alt but i wanted to maintain ac as an option later.

Id prefer to reverse throttle body and leave intake manifold alone. Any insight would be appreciated.

some engineering is needed to keep the t-body in it's normal location, as you found out there is no real way to flip the 2.5l throttle body due to the integrated IAC

flipping the manifold is an option. time consuming, but is an option. when flipped it will be a huge challenge to retain the Subaru a/c compressor.
