Decided to add a Red 46 skid plate to make sure I dont kill the oil pan on back roads.

Pros: works w/the gargastic x brace.

Cons: not bolt on

vbhargava

ProjectCoCo got some serious love this weekend.

New passenger fuel sender unit
New drivers fuel sensor o-ring
Garagistic rear shock mount reinforcement
M-tech 1 steering wheel with new M color band
New headlight knob
New glovebox lever/handle
New windshield washer reservoir and pump
New cowl grates

Nice subtle improvements. Those minor details count

YoungCR

Everything looks great! Especially the air vents.

Jdesign

Nice! Its all in the deah - tails.

Needed a jump start but Coco started right up for the first time since November. Had a few hours to make some small changes:

coco mats - black and grey
collector license plates (need to license plate delete the front)
new bulb in the rear bumper
realigned the m-tech 1 steering wheel 1 notch.
injector cleaner

Summer plans

raise coilovers 1 inch
euro grill and chrome kidneys
replace convertible top latch
license plate delete up front
replace coolant reservoir
maybe:
- 19lbs injectors and Mark D chip
- feupholster seats
- find a replacement front drivers fender

It’s been a while, glad to see progress. What tune are you going with?

@B C

I am deciding between a 91 and 93 octane Mark D chip- http://www3.sympatico.ca/mdsylva/products.htm. Any thoughts?

To be honest I'm having a hard time finding a step by step guide for 19lb injectors and understanding the differences in the various 19lb injectors iv found:

Do the installation of the injectors require anything other then swapping them out?

I would personally opt for the 93 octane tune and this set here

At most you may need to dremel new injector retainer slots in the upper portion of the body. I only had to do this once on as set of 33# injectors which had the clip location slightly different than stock. Many sets I have used did not need any modification.
Not required but good practice would be to do a smoke test to check for any intake leaks and make sure your oxygen sensor is healthy.

Thanks for the advice. Just ordered the injectors.

Are any of the cheap Mark D rip offs worth it?

B C

I dont personally trust them. They may just be copies of stock chips, they could have checksum errors in the coding, its a mixed bag. The real thing is cheap enough and easy to sell if you ever need to. I wouldnt be surprised if a fair amount of "tunes" that exist are just stock tunes with an increased redline. At least with the MarkD chip you know the timing advance is more aggressive which is where all the power is made.

Appreciate the advice. Ordered the chip and injectors.

Knocking out some of the small projects.

Unmodifying the front end with euro style grill, chrome kidneys and a license plate delete:

Coco mats:

Coco Mats are on my list as a final touch when I have the car back together. How do you like them? I assume there's nothing not to like about them.

They are much better then stock (I hate the stock ones since they get stuck in the pedals) but to be honest for their price point I would expect better floormat templates for the rear seats. Overall I really appreciate the look and would probably still purchase again.

That's good to know. Unfortunate about the rear, but since those aren't super visible, that doesn't sound like it would be a deal breaker. I plan on doing black with red accents for the cardinal interior.

@B C Unfortunately looks like Maks Injection went out of business ... right after I placed an order. Time to find an alternative.

Now, be wary that fake Bosch injectors exist on Ebay and elsewhere. Normally they are the larger flow injectors that people use in turbo builds but I wouldnt be surprised if China has tackled all popular sizes by now. Performance wise they work fine compared to the real thing, but around 80%+ duty cycle they become erratic in the tests I have seen.

Fake Bosch injectors have Bosch logos and come in Bosch branded boxes even claiming they are made in Germany. For this reason I am wary of lower priced new injectors and feel better buying ~$75 reman. injectors.

be advised

@B C I had a mechanic friend install the injectors and chip today and we cant get the thing to start up. Any chance you have 15 min to chat tomorrow?

How’s the Red 46 skid plate treating you? I’ve looked into, would be nice for piece of mind, but the M20 oil pan isn’t nearly in the way as an M50 swapped car is.
