Nah it should be fairly easy, I done an LT10s on an SR20det a few months back and it worked this one is pretty much the same apart from the sequential ignition

had a play today and put the tank sump on

Why did i opt for this over a surge/swirl tank or a fuel cell....well i dont like the idea of fuel system components in the boot on a street car and theres no room underneath for a surge tank plus i like the look

even with an external surge it will still have a tiny pickup tube and have problems supplying enough fuel

before doing any work on a fuel tank make sure it is professionally cleaned, i got mine steamed cleaned at my local radiator shop

heres the sump, made by competition engineering has two 1/2" ports
Image

once you decide where you want it you need to drill some 2.5" holes a template is provided, mark and drill the pilots holes then run through with a hole saw

Image

Image

look fuel tank + flame and no boom boom, like i said get it cleaned well and it will be 100% safe to cut/weld
Image

Oh heres that tiny pickup tube
Image

welded
Image

I had to cut and fold the sump to follow the profile of the tank, a sump to suit a mustang is already the correct shape
Image

painted...yeah i know i said i was going to powdercoat it but meh its still sexy

yeah... i like that. heaps better idea than a surge tank in the boot :think: .

Whats the legal side of cutting and modifying the tank? do you have to go through anything extra?

needs to meet ground clearance and dimension adr's, it may effect the vehicle’s departure angle but who knows its not something that needs o be certified, all i can do is drive it and see how the fuzz take it

A boot mounted fuel cell/surge tank needs to be certified, boots need to be fully sealed from the passenger compartment and drains need to be incorporated into the install in case of fuel spill/leak

Great job on the Fuel tank Mick!!
Ha if you get pulled over for the fuel tank, that will be the least of your worries with what you are doing under the bonnet ;)

Atleast it will be black and harder to spot!

Also if you dont already have it, I have a copy of Microteck LT series wiring diagram book.
I can send you, or anyone else a copy.

cheers Dan

I dont think i'll cop much grief with the tank, though i think you may be right about the engine bay mods :)
funny thing is, I was driving this every day and passing a lot of cops even got pulled over for a breath test and they dont even care to question me about it :lol:

Thanks for the LT manual offer and yes i do have one here, though John from Microtech has drawn up a wiring diagram for me as its a somewhat unique configuration

lol its like Mitsubishi designed it for the controller, dont have the GT42 any more though I wish i did theres a heap of room on the drivers side :)


mstrrab1992 yep its legal registered and engineered, The next engine swap im planning will push the limits but I have the OK from my engineer and it JUST fits in to the RTA guide lines by a few cc's, its a smarter option and one that I should have gone with from the beginning, good thing is the Microtech is already configured to run the planned engine.... funny that ;-)

well siggy is on a diet now its waaaayy to fat, so im stripping all the stuff that makes it comfortable (kind of)

I'll edit this post with a list of mods/removed bits and what they weigh

so far i have remove the sound proofing and under felt that was 22kg

drivers seat 18.5kg
passenger seat 17kg
Im tossing up what seats im going to fit, theres 3 reasons im swapping seats

1 drivers seat is broken

2 need fixed back seats for racing

3 std seats are heavy mofos

I have a choice of two seats one is 7kg without rails (on right) and the other is 9kg with rails (middle)
