Where do i start with updates ..

Since the last update i have done the following: -

Cleaned and painted the croma engine, built gates into the sump, replaced the mains and big ends, installed ARP rodbolts, swapped the camboxes/cams/distributor with the Delta GTie non turbo ones which are quite a bit more aggressive (i had them doctored by Franklin Cams). Also used the Delta GTie camgears as they are quite alot lighter. I swapped over the intake manifold and fuel rail from the Delta GTie, with 440cc top feed injectors from Mitsi Evo1 / VR4. Have also swapped over the fuel lines with the GTie ones, and run a Bosch 044 replica fuelpump. To go with it, i have swapped to a Delta Mk2 HF Turbo and run the GTie oil pump and pulleys. The loom has also been fitted from the Gtie and the shifters and gearbox. The Flywheel is GTie, but has been redrilled to 12mm bolts to suit the Croma crank. Autoclutch has made me a killer carbon/kevlar 2200lb clamp clutch which should deal with up to 500hp on a single sprung plate.

I have fabricated the two lower engine mounts using 5mm plate, and the utilising the mk2 delta Gtie mounts. The upper mount is GTie, and the engine mounts are from GTie also. The radiator still fits from the existing HF Turbo, but i need to check out the radiator fan.

I also fabricated a strutbrace with rosejointed ends, which integrates as a torque mount for the engine under load.

The Turbo i have used is ex Stacey James who used to race a hot 130TC abarth in Targa. I believe it came off a punto, but its a T28 from Nissan Pulsar GTIR, modified and rebuild with a genuine garrett cartridge and tweaked slightly by Steve Merch, so it should have good boost response. Also have used a T2 manifold from mk 2 delta HF turbo.

Mark from Lynchbuilt fabricated up a 2-1/2" V-band downpipe to plumb back into the mandrel bent system that we built a year or so back.

We have also run a bigger aftermarket intercooler designed for GTS-T skyline R32, and a 16 row oil cooler. I have run 2" pipes into the bottom of the turbo, and 2-1/2" back to the plenum with an HKS SSQV blow off valve. Just working on oil cooler fittings at the moment.  I also cut and wired the injector plugs from an Evo back into the loom as they are all high resistance (16ohms).

There has been a whole lot more fabricating needed so far than i initially expected, but am making headway slowly. Heres some pics for a quite squizzy ...
