General info:
2003 Sonic blue convertible (110,000kms)
V2 VORTECH running with. 6rib pulley with 3.12mm
Tuned on 94 and capped at 5500rpm with an Anderson power pipe and a blowoff valve.
Stock internals
3.73 gears
3inch cat back borla S type
Stage 2 racing clutch.
Stock tranny
Romeo engine
And an air freshener for biddazzel
The bad and ugly:
Was driving with the wife last week and I was coming off a red light, I shifted from 3rd- 4th at 3500rpm and I felt the car running really rough and a loss of power. Now I’ve had the power pipe come off and give me the same effects but it wasn’t the pipe this time. First reaction is I must of spit a plug.
So this weekend I I found both cylinders 3-4 are down ( rear passenger side motor). I found 1 plug crushed in on cylinder 3. And 4 was badly burned.
So I changed all plugs and coils. Injectors are running fine so I have gas and spark. Engine is still running badly!
Buddy of mine points out my tensioner is rattling, and said he’s seen this happen before to other 2vs.
To make a long story short we suspect the crappy lashes tensioners and or chain guides let off a piece and took out 2 of my cylinders.
So now I either redo my motor or I swap. Covid prices are insane.
The Good:
I was thinking of rebuilding my motor anyways, and I have a second low Kms motor sitting( has a knock but I can swap some parts).
Now, I think I’m leaning more toward rebuilding my motor. Since I’m going to take it apart anyways I was hoping someone could give me some direction. I’ve decided to keep my stock crank cause I don’t want to go to crazy. But I do want to forged my motor and pulley down.
Upgrades I need advice on.
Lashes/ chain guides.
Pistons and rods ( should I bore and go bigger ?)
Cams
Valves/springs
Injectors
Main bolt studs ?
Am I missing anything else ?
