Ok, I just swapped an LQ4 into my GTO and am wondering this....
I bought the LQ4 as a longblock. I have all the truck accessories etc...sitting in my garage. Would it be possible to use a Maggie off of a 4.8,5.3,6.0 truck application, if I used all the truck accessories? I know they are obviously quite a bit different in design. I just wondered what might cause me issues if I was to try it.
Also, how much HP are these LQ4 short block holding up to?
Issues I know will need addressed:
1. Relocate battery to opposite side for air intake
2. Snout might not clear hood
3. TB adapter would be needed
i dont see why you wouldn't be able to use all the truck accessories, it would just take some fabrication work and time to find out what will and what wont work
btw how much did you get the LQ4 longblock for and how much boost are you planning on running on the stock internals?
and is the LQ4 the same block strength as the LQ9 and the only difference is dished pistons/flattop pistons and the compression ratio/camshaft?

I bought this longblock for $600 with 36k miles on it. I was only planning on 10-12psi. I have a set of Ported and Polished heads at the machine shop right now being milled so I will end up at about 10.75 compression. As for strength vs the LQ9, I am wondering the same thing. I put my LS2 front cover and camshaft in this and it runs great. I just don't know much about what these blocks will handle.
Test 1 was with the stock, iron 6.0L short-block and production iron heads assisted with a GMPP single-plane intake manifold, a 750 Holley carburetor, and a set of 131/44-inch Kooks long-tube headers.
Test 2 kept all the original changes from Test 1 but added the GMPP hydraulic roller Hot cam and valvespring kit.
the stock cams in the LQ4 and LQ9 seem to do pretty good for how 'small' they are

That might explain why this motor feels so strong then. I have the LS2 cam, Kooks 1 7/8 LTs, 3" catless exhaust through Magnaflows, 241 heads, P&P TB, Stock air box.
This feel like it has much more power than my LS2 did. If I can get a maggie on here whether I can use the truck style or not, it should put out some great numbers.
and btw, if you're using the truck block with all the accessories, why not use the whipple supercharger they make for the trucks and modify the kit to work accordingly?
Im pretty sure your gona have issues with the firewall. the reason the GTO setup is different from the truck setup is because of the clearance issues
This is the info I have been looking for. I know it's hard to tell by looking at the truck style maggies. I just wasn't sure how much of a clearance issue it would cause. When I look at pictures, the air inlet looks like it sits just forward of the back injectors, which would make me think it would fit ok. If I had to cut some of the plastic cowling for it to work, that would not be a big issue. I hope one of the experts can jump in here and clarify the design difference and what issues would definately be a problem.
