Pretty much everything you have done since the event that sparked the rebuild. I understand you are using a Tipo head and a LH II ECU for example, but sounds like you have done a host of other mods. Did you retain the idle control you had added to the car previously or does the LH II take care of that?
Cheers, Dom.
Hello Dom
LH2.2 includes idle control, with AC adaptation also.
I can't remember all the minutiae within the motor - essentially 1600 crank,
oversize pistons 86.96mm, for 87mm bore (
flycuts increased for 37mm intake valves) & scat rods. This should cover the rest - I'll add to it if I miss something to keep it all in one post. I'll add links to specific posts that show the referenced item.
True TDC markers verified.
Compression Calculations Sitting at 10.7:1. Tipo head with 39mm intake valves/ 33mm exhaust valves installed (EDIT: exhaust valves are 31.5mm). Heater port added to front, EGR port welded over, combustion chambers increased to give
34ml volume. Isky performance valve springs.
T/stat housing adaptor made to go from Tipo flange to X1/9 housing.
Adaptor flange for heater/branch pipe to bring return elbow hose back into alignment.
Branch pipe also 'squeezed" for clearance of Allison Headers (previously installed). Heat shield between headers & intake made from Volvo '00 V70 turbo upper heat shield.
T/Belt Tensioner
base plate slotted to allow coolant drain away from bearing
Oil pressure sender (gauge/light) relocated to lower early style port.
Dogbone re-bushed with Volvo torque mount bushings
Snail mount bushing replaced.
Front upper timing cover shaved to clear revised heater feed port.
Using shaved cam box & 35/75 cam previously bought from Bayless for last setup.
Replaced Cam with D-223
Miller's Mule adjustable cam gear.
VW starter relay kit installed.
Volvo
LH2.2 (240) wiring harness cut down to align with X1/9 component placement in engine bay & installed. Volvo harness grommet fits existing firewall opening without modification. Uses stock X1/9 FI throttle switch, replace CTS with Bosch 026 (Volvo 1332396)
Volvo
LH2.4 Conversion, requires crank trigger wheel.
Custom fuel rail &
modified lower runners for
0 280 155 742 16lb injectors (from Mercedes application) EDIT: Using
200cc injectors 0 280 155 746 from Volvo 850 NA EDIT:
24lb 0 280 155 832 injectors installed with LH2.4.
EDIT Custom Fuel Rail v.2
Custom Fuel feed & return using Volvo '98 V70 Fuel Pressure Regulator pod & modified lines with quick release fittings. Fuel return side now contained on left side of compartment.
Volvo ('85-88) 554 ECU & 007 MAF installed, custom ECU base bracket required.
Volvo ('89- 240) heated O2 sensor (wire harness is long enough to route around left side of frame) installed pre cat.
Custom intake
("J") pipe with silicone couplers for MAF & plenum fitting (previously made)
Custom IAC installation using a mix of Volvo hoses
(see CIS MOD)
A
llison Ignition with Bosch copper plugs * .045" (previously installed, see thread) I may build an EZK ignition, as the Volvo setup includes knock sensing, ignition timing control based on inputs from AC & coolant temp (advances timing at idle when hot to keep EGT's down), monitors engine load, etc.
EDIT: Volvo EZK 117
installed with
custom distributor
Serpentine Belt mod for AC setup
(see thread)
Revised
Oil Cooler mounting (previously added system using Volvo parts)
Exhaust compartment heat insulation replaced with DynaMat/Liner, stock shield modified to allow air passage on left side for oil cooler.
Rear control arms re-bushed. KYB struts installed. Rear brake hoses replaced.
eBrake cables replaced, all pivot/pulleys cleaned & greased.
Clutch pivot arm refurbished, brass top hat bush fabricated for pivot in bell housing. New T/O bearing installed.
April 2016:
Converted to LH2.4 and EZK116K 6842115 & 3517402 ECUs
3" Inlet piping & revised IAC routing
Revised Branch pipe for increased header clearance
Wiseco pistons installed after HG failure & Mahle piston damage
Wasted Spark Mod for EZK116
Higher flow electric cooling fans
