Greetings,
I have a 1988 1275 Metro engine that I purchased that is very clean and I am in the process of supercharging it prior to installation in my 87 Mayfair. The prior owner did a VTEC swap and the shop and owner said it was a very good engine. I have a basic SC kit (much like the Janspeed one). I do not plan on rebuilding the engine at this time, but I will measure to make sure it has not been mucked with. I know a decompression plate is not ideal, but that is my plan for now. Someday I wall do a 1293 rebuild with dished pistons. I have a few questions:
- I understand the Metro runs at about 10.5:1 CR, with Janspeed's 6CC plate it brings it down to 8.4. I have contacted them and they said that is on the high side, but doable. I think they offered a 9CC plate at one point which would be perfect and I asked them about it, but I have not heard back yet. Is 8.4:1 OK? Is the VMAXSCART plate thicker?? I am in the states and have access to 93 octane which I think is 98 RON. I could add octane boost.
- I found out that the distributor on the engine is not standard. It is a 59D4. I checked the stamping on the block (12HD24) and it is an 88 Metro 1275 for sure. The specs on the dizzy run 1-20 degrees (vacuum). I know this is an older style dizzy, but from my readings this may play to my advantage? It seems like at 20 degrees max, this will give me some boost insurance. Thoughts? I could get a 123, but hey if this works for now...
- I plan on ordering the Janspeed needle for my HIF44.
Thanks!
