Of course spectre only makes a 3 and 4 inch version, where the old style had a 3.5 inch inlet i believe...
I'm using 4" tube with no issue on my LQ4…The Spectre stuff comes with a reducer ring, FYI

Each different style MAF requires a different calibration table. They are not directly interchangeable. LS2, LS1, LS3, and truck. Changing a the tube size for a cartridge MAF requires a new table. It will run lean, and may throw codes if out of range. I install the LS2 MAF table my customers for this conversion.

This made me curious…so I looked up a K&N kit (which I wouldn't buy) and they supply a 4" ID to 3.5" ID reducer for thier kit.

Does that help

Seriously considering a GM engine for my '85 Ninety...

-Is there a code name for the GM gen IV engine? Are there different versions? What year(s) was it used, and in what?

-What's the best automatic transmission to use?

-Will I have to upgrade my diffs/axles?

-Does anyone make a big brake kit so I can still stop?

-Will the exhaust system need to be built from scratch?

Thanks!

Paul.

Paul, you've got some reading to do. All of these questions will be answered in this thread.

The problem is that the thread will only get longer if the same questions get asked over and over. Most of these questions will be answered in the first few pages. Yes there are many engine codes, some given originally were: LMG, LC9, LY5, LY6, L92, LSA. Choose your displacement and go from there. Your transmission will be 6L80E. Just make sure its 2011+ if your engine is 2011 plus. Yes there's a big brake kit, I think Alcon was working on something snd there's another company that someone posted in this thread. Nicholas makes a downpipe with cats that bolts to the NAS style cat back. You should be ok on stock axles depending on what engine and how you drive it. Any off-roading and you will want upgrades.

And if you wanted to keep costs down and go with a manual box, go read the Gen III thread

Short answer is:

-You can run any of the Gen IV engines, whether 4.8, 5.3, 5.7, 6.0 or 6.2. They each have their own engine codes, often times several for a given displacement, so research and figure out what is best for your wants and needs. If you're shopping for all new pieces, Turnkey Engine Supply offers a very nice engine and transmission package using the L94 that is configured for these trucks for around $14,000.

-The ONLY transmission supported by Nick's kit is the 6L80. Unfortunately it isn't the most common transmission out there so if you're hoping for a complete powertrain out of a wrecked vehicle you're going to have to scour pretty thoroughly. I believe only the 6.0 and 6.2 equipped vehicles came with the 6L80 from GM but I could be mistaken.

Marks 4WD in Australia offers a kit for the much more abundant 4L80 but after having just completed a swap using their kit I'll never use it again. Nick's is far superior.

-If you aren't drag racing or doing any crazy offroading you ought to be able to make the stock R&P and axles last just fine. Drive like a madman and you'll probably need to upgrade to chromo shafts and stronger gears.

-Alcon and Tarox are two that come to mind. Not a complete necessity but you can't have too much braking power in my opinion.

-If you use Nick's Y-pipe you can use any of the cat-back exhaust systems available for the Defender from companies like NRP, Borla and Magnaflow.

That should get you started.

-Ash

Thanks guys!

For those of you who don't know, I'm building my Ninety to take to the USVI when we retire in 5 years. Very steep hills, max. Speed is 35mph, so I'll need bags of torque.

Before I dive into researching the characteristics of the different displacements, is there one that shines above the rest in terms of low end torque?

I know the Tdi's have good torque, but I really don't want a diesel.

Last stupid question- do they all run on regular petrol?

Thanks again!

Paul.

hi,
thanks for the reply, the use is i guess 50/50 off/on road. we don't do much rock crawling here, soft sandy dunes, i luv to play with the right pedal. theres a video of 110 that nearly clipped a wrangler somewhere in this discussion; i was there physically and my friends were lucky nothing happened but back to the subject ; thats the kinda play we need here to tackle 100ft sand dunes.
as to my differential I'm using aschcrofts air lockers front and back. wheeling is 35 inch toyos all terrains on 16 inch terrafirma beadlocks.

What differentials do you have? You say shafts, flanges, R&P and CVs, but nothing about differentials.

what sort of fuel mileage do these trucks get with the LS?
Is there an option yet for a manual transmission? Seems a shame to lose the manual for an auto
