QV efi conversion

A change of pace this weekend. Reg asked is I could help him by converting his QV intake for efi, so here we go.

The first thing is knock-out the CIS junk

Next the bosses are all in the way so using the original counbterbore as zero, I mill across 0.300" deeper about 1/8" outside of centerline.

Then I pop in new c'bores .750 dia x .900 deep. There will receive plug that can be machined for hold the new injectors as the stock holes are already too large.

Reg I forget, is this the one you're putting the bike TB's on? Running from a Haltech?

'99 550, Rosso Corsa / Nero, S/N:114654, Assy: 31836, Engine: 52084

High mileage, low compression, and missing on a few cylinders.....just like my cars.

I didn't get as far as I hoped, but still got a lot done.

First up I had the machinist make up plugs for the CIS injector holes (he was very proud of himself and I'd say about 1/2 as proud as I was of him) that got pressed and then welded for good measure.

Then on to the machining.

Machine back to -.300 depth
-Drill a 29/64 through hole for the injector tip
-Drill 17/32 x 0.550 deep then ream to 0.550 for the injector o-ring
-Then I mis-use a 5/8 center drill to create a counterbore with a 60(included) angle on the bottom 0.400 deep. This lets the injector body drop in and the angle works nice to compress the o-ring durign assembly.
-Cut a place for the fuel rail to sit
- 2 M6 holes to bolt the fuel rail.
- cleanup the inside (no pics, I forgot )


....now I just need to actually have a fuel rail.

Mark, that's great that your son is interested and participating in this. Too many these days are stuck into their iPads and other electronics, and are clueless about the real world.

Its a double edge sword though because earlier in the morning he showed me a track loader from his hess truck and a transformer and was asking if we could take the backhoe off the track loader and make an adapter to "peg it on" to the transformer. "Peg it on" appearently means it should by light press fit into 2 existing holes on the transformer so it can be popped on/off. Very creative and I'll help him with it as soon as I get the manifold done.

Lana on the other hand was not particularly amused that neither he nor I saw anything wrong with the idea of mix and matching parts that clearly do not go together. What she saw was us plotting to ruin 2 toys just like the 2 or 3 engines I ruin on my V12 project

. Soundwave (a transformer) suffered a broken shoulder during battle

"Papa? Can we fix this?" 2 hours later Soundwave had a new billet shoulder to replace the broken plastic one and little one was as happy as could be. Keep in mind this was only a $20 toy to start with and the store is less than 15 minutes away....but it was well worth the 2 hours. I'll have to post some pics tomorrow.

I spent a few hours day making the fuel rails and started the work to clearance the TB to fit around the fuel rail.....almost there. Then I just need to add a TPS to the TB (the US cars came with them but this is a Euro car and they didn't get them) and it's time to ship it back to Reg and get back to my V12

Pics of this tomorrow too.

Here's the repair of Soundwave. I don't usually do tiny parts and really had to dig to find tiny tools to cut it, but little one was thrilled when it worked again.

Getting the TB on is a challenge. I tried to keep the idle adjuster screw on the bottom......but after 2 hours of screwing around with it I cut it off and moved on. The first couple conversions I did I sawed it off straight away but on the last one I decided to keep it and was able to make it work after about 6 hours of screwing around with it. Any future conversion that silly thing comes off which is about a 30 minute job.

I still need to clearance for the throttle linkage and add the TPS but I have some family time to do right now.
