I have been a tease for the last few months while I have been working on it. It should be running before the end of the week. Here is my collection of photos from the work I have done so far.
My old setup was a bone stock M20B25 with almost 200k miles with a t3/t04e 57trim w/ .63 exhaust housing with a volk adapter, MSnS etc etc.
I put down 238.5 whp on that setup @ 10 psi.
The rings and valve stem seals just couldn't take it anymore and have been blowing ALOT of oil and crank case pressure lately, so it was time to build a new better, more powerful and more reliable motor. Here are the currentish spec list.
1mm over bore 8.5:1 JE pistons w/ raised wrist pins
Eagle ESP 135mm rods
ARP rod harware
ETA (81mm crank)
ARP mains
ARP headstuds
Cometic HG
All new bearings, seals and gaskets
New Oil pump
273 cat camz w/ 11.5mm of lift
New rockers, shafts, IE valves
welded coolant channels
HX35 w/ 14cm^2 non WG housing on a volk adapter
Also:
Perma-Cool Oil Cooler behind kidneys
60# injectors
GM Waste Spark Coils
Euro Grills
Smoked Hellas
Delrin shift console mounts
rest of the shifter shims/bushings/clips
Lightened (3ish lbs) single mass flywheel
From the Old setup:
2.5in IC piping
20x12x3in core bar and plate IC
HKS SSQV BOV
MSnS PCB v3.0
full 3in turbo back exhaust with borla XR-1 Muffler
Tial 38mm WG
Clutchnet sprung 6 puck disk
Sachs 618 PP
Sachs HD TOB
I started out with having the head cleaned, then welded, straightened, resurfaced and valves ground.
I then brought my block, pistons, crank and flywheel to the machine shop for a bore, clean, LIGHT micropolish and resurface (flywheel).
Got the block back and masked, primed and painted.
Put the whole rotating assembly together, oil pump, water pump, front and rear main seals. It is coming along nicely.
Just finished it up. Installed valves, springs, cam, rockers, shafts, head studs, head onto the block, timing belt, MLS HG and whatnots.... Sorry a couple of the short are HORRID..
Got the motor pulled out of the car and torn down to a bare long block. I am going to be cleaning and transferring the good parts over and get it ready to be dropped back in. I need to clean the engine bay and take care of some wiring before that happens.
Stock Single Mass vs. Shaved Single Mass.
I cleaned some parts, installed studs into the head, got the manifolds on, thermostat housing and going to get the oil pan on and get started on accessory drive stuff next.
I got the engine dropped into the car with transmission. Got my oil cooler and IC setup figured out and tore down the old engine. I found a solid 100% head gasket, 3 broken compression rings and sludged up oil control rings. 201k mile turbo m20 didn't like that extra pressure and potential timing issues when I was running motronic for spark previously.
Broken ring with some pieces I found.
Easy oil change and Oil lines (not secured or connected yet)
Sleeper oil cooler and IC setup. :) Also ability to run 4 headlights.
Welded a new flange on my DP, made a dump tube, installed DS, rebuilt and installed shifter, rebuilt turbo, installed turbo, wrapped DP and installed. Did all the oil line plumbing, hot side charge pipe, radiator, headlights, grills etc etc..
Thats it for now. I have wiring, cold side charge pipe, exhaust (just reinstall), reinstall power steering system and a few odds and ends. Should be running shortly. :)
