there is a fully rebuilt gear drive engine in Cochin.. rebuild warranted by a leaking oil hose..

otherwise there are enough of the scorpios out there with 2L kms running.. so not really a huuuuge issue.

having used the army 550 and scorpio with the 30 spline rear axles, i realize they are faaar superior in strength and tolerance than the 19spline in the full floaters..

The meshing is clean and no whines..

Plus you can find a army LSD and plonk it

Dear Shubhendra - PLEASE DO NOT BUY GEAR DRIVE NEF ENGINE. PERIOD. I will explain you when we meet, probably in the coming week itself. .

Dear Prabhuav - it is a much bigger and HUUUGE issue than you think, I request you to believe me Sir! .

After driving more than 4k kms Found few problems with the top end rpm. Engine lose its power After 25000 rpm. Solved the problem by step by step modifications in Intake,Fuel,exhaust.

First removed and rerouted the Air intake.

Custom intake with 3 90degree bend and 2 L hose bend.

Sreejesh,

You must've developed a new liking for school reunions now

1) What size dia is the exhaust pipe?

2) Does the electronic FP only help with starting? How does it help with top-end?

Amazing amount of work has been put in to get this Jeep to where it is!

Cheers,
Adi

Hi Adi,

I modified the same NGCS exhaust pipe. not sure the correct diameter but bigger than the 550XD , old jeep ones.
EFP works as a support to FP. FP don't need to work hard to pull diesel from tank that is FP just need to take the diesel which is already available from filter by EFP.

I also have a EFP fitted as initially I had starting problems after extended durations of being parked. Did you keep a separate switch for the EFP or is it direct on ignition? I have it directly but the only issue is you may not want to keep the ignition on without starting the engine for long durations.

Adi,

Which model EFP you used ? I am using a less pressure EFP it just give enough flow without pressuring the FP. I am using ACC ON position for all my accessories and EFP connection from ignition.



Installed AC from Wecool. Thank you Jaggu for suggesting Tobias for the work.

Tested for a 100km drive with AC and a 17km Ghat section. Its works perfectly and does the Job effortlessly as the blower fixed on left side air throw is not good but it cools the cabin very fast so going to add two more custom vents on right side.

After fixing AC did few Offroads but the one with Jeepers Of Bangalore (JOB) at selam was the best private Offroads I ever participated. I am happy but not fully satisfied with the current combination at above 3000+ rpm.

Shubhendra Ji,

Putting a turbo on a NA engine is not that complicated But removing a Turbo from a engine that is especially designed with Turbo is complicated. When I did dino on my jeep I am surprised (disappointed) with the 50% power lose.

Bought locker from Gowtham for My War horse Its pretty cheap and hope will do the job. As I am from a village Its difficult to get Parcels on time. Called Gowtham and he send another locker directly to My Mechanic by a BUS. Installed the locker and waiting for the delivery of Jeep tomorrow.

Torbo charged the engine and the engine sound itself changed from the Tractor Di. I am going for a Bigger Intercooler with custom Radiator .

NGT530 and Rear LSD put on Hold as I am going to Shekleshpur For a Proper test on Turbo & Locker.

That Army Brake light Assy was keep hitting on rocks so thought to do a custom lights.

Hi Sreejeshmp Sir,

I have utmost respect for your vision and thought process for your jeep.

I have followed closely and with admiration you meticulous and step by step build.

Seeing that you have chosen to go with the locker from Gowtham is something i am very interested in.

I would love to hear about how it works out for you and how it holds up.

Thanks,
L.o.R

After participating Shekleshpur OTR with family I understand serious offroading is not a safe and practical thing with family.

Now the plan to maintain jeep for both On road and serious Offroad is not going to work for me. So making the jeep as a Offroad vehicle and Converting Sierra in to 4WD for normal offroad events and a CJ8 Scrambler replica from my MM Pik-up for farm use.

- Sreejesh
With the standards set up by Rfc india for offroad vehicle preparation, the gap between the competition spec vehicle and our beloved Jeep/Gypsy is quite huge.

Since you have already done so much to get your war horse to the shape it is, why dont you consider to build your war horse to be one of the best built Jeeps around. Once they go RFC style, it will be another dimension from your current build. Just my opinion.

Btw how was the performance of the lockers? Feedbacks please.

Regards
Barani

As usual I finished the modification on night and very next day drove to Coorg to attend V5 Offroad Event. I was sure I wont get better track to test to the max on performance and reliability of the build.

On the way to Coorg at Tholpetty Wild life sanctuary.

It performed well and my confidence level increased and the result was this
I entered to the water crossing without Snorkel. I am sorry My Jeep that was my mistake.

MM550 XD NGCS - The War Horse-img20141214wa0014.jpg

Engine stalled and winched out from water and towed to Garrage. I was lucky again that Mech at Gonokoppa is My Mechanic's brother. I kept the jeep there and went back to home. Nothing happened except the Starting motor got Stuck,Battery Drained and Water entered in to Diesel tank. Got everything fixed and drove the Jeep back to Home.
