Thread: P38a+350(LS1) Chev+4HP24

I'd like to do one, If I can get another cheap enough P38, I think I'll lift the gen3 from the jag and have a dip

When I was tempted I was going to use the existing ECU, sensors etc and fit them to the motor, fair bit of getting right, but its only machineing

check out:
RangeRovers.net • View topic - LS1 conversion Thread - Ideas, Thoughts, etc

there was a small firm in the UK which succeeded and conveniently used the GEMS sensors on the LS1 which was then converted to run on LPG. Their website is/was LS1-power.com I understand they are no longer in this business

The venture cost them a heap of money apparently and they were stuck with a supply of cast bellhousings which needed further machining.

I did manage to take a copy of part of the website -of interest are the following:



Standard conversion

5.7 LS spec engine.
Custom bellhousing and torque convertor mountings
Bespoke engine mounts
Exhaust interface to standard RR exhaust.
Upgrade fuel delivery system
Relocation of standard ancillaries (Aircon, PAS)
Supply of new alternator and wiring
Modification of looms
Custom programming of GEMS engine management.
Airbox modifications and silicon intake hose
Electric fan and adjustable controller

Sorry I have no other info...
cheers

I know a bloke in cranbourne that could help sort out the electronics side of it, ie ecu/powertrain.

Mcrover?

Just got back. Happy New Year to all.

Rovercare, I saw your response in my other thread. Agree that the best way would be to use the GEMS ECU and modify sensors etc to fit the GENIII, but how could it be made legit fro a pollution standpoint without spending a fortune on testing. One of the engineers I spoke to was happy as long as I used DELCO ECU cats/airbox etc...

I was also told to upgrade the brakes I don't see how as the current disc/calipers only just fit inside the 17inch alloys.

Body Computer communicates with the Engine to deactivate immobilisation, otherwise no go. You can now by Kits that bypass this.

Engine communicates with the Gearbox by hardwired lines pre 1999. It feeds in a Torque signal and receives a torque reduction request.

Basically, IMHO the best outcome would be to interface the Delco ECU with the Body/Trans ECU using the GEMS box as a translation device. This would cost $$$

The cheapest/easiest would be to Modify GEMS to suit the GEN III, and if you can get this past an engineer even better.

I currently have a P38 with no engine, but I also have no money.

You would also need to make custom engine mounts, but otherwise OK

Anyone else no anyone the same, but willing to sell cheaply

Sorry Stu

No offence to McRover, but judging by his first post, I doubt it.

I haven't read your original thread, so I may be behind the eight ball, but I'm fairly sure you'll find the original ecu (GMH) can be reporgrammed to delete stuff like the body computer/imobilizer request, as well as certain sensors and the like.
I see you live in ringwood, if you are still interested in doing your project, drop me a PM, I can put you in contact with the bloke I mentioned before, (he lives in Mt evelyn, works in cranny). He's been involved in fitting ls1's to various projects.
