I didn't really know how to start this post without sounding like the new (I'm not young enough) pretender, look at what I've just had done. Everyone else who have turned to the states side have done so by their own hand and ingenuity. I however, only have tools and equipment for modest diy mechanicals so when the 4.2 ajp needed even more money thrown at it my mind was made up.

From quite some time ago, after seeing Jon's purple monster (ooh, I say), I decided that if my engine suffered a major catastrophe then this would be the way to go. The moderate, justified bills from the 4.2 came in but no blow up. I didn't actually want it to. I haven't got lots of money to throw at a car but sometimes enough is enough.

The car was at my local which is Topcats. The engine needed labour intensive work which we all know is the expensive bit but very fixable. I knew they ran LS engines in their race cars and are a race team so know how to work with these engines. So I asked, "Could you put one in the Cerb?" and they said "We could certainly do that for you if you want". I do want, and so started the customer car project.

The timing was right because the '08 LS3 was the most recent generation to get and even though I said I was on a tight budget we agreed (both thought it was needed) a TKO 600 g/box would have to be used. I have to say, there was a great deal of thought went into the installation of the whole set up an the result was superb. Lift the bonnet and it looks as if it was meant to be there. The Topcats guys did a fantastic job of the car.

Performance is staggering (on private ground), but it only is on the road from (tax disc) 01 Feb and I can't wait. As it is, it would not compare to Brummie's Chitty Chitty Bang Bang but it may be in close second. Whatever it is, wow, it is fast!

P.S I am considering changing my call name to "Hedgehunter" and the car too. Do you think the humour will be lost on the god of fate?

Just in case anyone thought I was being derogatory towards Brummie with the CCBB comment, it was meant in respect. You're still top of the list.

I suspect you are another of many cars that will be converted to LS power over the next few years. I have to admit I would like one of each. I am sure the 4.5ajp will have some collectors value (unmolested) in the future and the other car would be for fun with few expensive mechanical worries.

Yep we need pics. The LS3 seems to look a lot prettier than an old SBC, and from the pictures looks a good deal smaller than the prettiest, an LS7.

Someone really needs to see if an LS7 with a kinsler stack can be fitted in a dead Cerb. cloud9

I'm sorry but I'm a bit of a computer dinosaur and also I have yet to take recent evolution pics. That was my '09 resolution- to understand how to be more interactive and do this kinda stuff. I'm learning and I'll do what I can.

Secondly, after the pioneers come the explorers, then the trail blazers. So, I'm sure more are to come with bigger stuff than before. It's evolution and good or bad it's coming. IMO

The LS7 and LS3 have the same external block dimensions, the biggest difference is that the LS7 cylinder liners are 4.125" diameter and pressed in, where as the LS3 has liners that are 4.065" diameter.

From what I under stand most of the comments its the oiling system and accessories from the LS7 install which may be difficult to install.

The LS7 is a larger bore size, longer stroke, a better set of cylinder heads, a better intake and a dry dump oiling system when compared to the other LS engines such as LS1, 2,3

Interesting, never really looked at the LS3. Before it came out and when the pound doller was better I was seriously thinking of a kit car powered by an LS7. I got offered one at £6K, brand new crate and an extra £500 for all the ancillaries. I hated the look of the engine though, till I saw one with kinsler stacks, then I thought it looked really georgeous. Its funny how a small difference made such a big one.

Now with the pound against the doller I wish I'd bought one.

In the kit car I was planning the engine would have been 'on show'

Is it a bog stock crate motor, or have you had it cammed etc? No offence taken, But is it because i look like Dick Van Dyke confusedsmile

Sounds very interesting, did you manage to stick to your budget, or did some unknowns crop up?

What happened to the old engine? By labour intensive, do you mean the valve adjustment for the AJP or was it something else?

Below is a picture of a 5.7 litre LS6 with magnesium Kinsler throttle bodies, roughly placed in my Sagaris V8



In the end I wasn't able to use the Kinslers as the engine sits so far back in my chassis that it tucks right under the windscreen scuttle.

In a road car you probably wouldn't push it back so far and may well be able to use them. There was plenty of under bonnet room for me (although mine has a very low profile dry sump), the issue was the windscreen scuttle.

Kinslers are worth 10% power gains on their own, but they are expensive. (As an aside mine are for sale....)

AJP70, I can take any pictures you need and post them, I am near oxford. Was thinking of popping in to Foxcombe Lodge on Thurs, but would be better in daylight. Let me know

I put a FAST manifold on with a more aggressive cam and saw 70RW BHP, so would the Kinslers offer even more?

Yes, the Kinslers are a big improvement. I was gutted to have to remove the Kinslers and replace them with a FAST throttle body and polymer intake. It was a step backwards.... and it cost me money to get less power!!

Most of the LS7 people were quoting 505 to 525 with the stacks. Maybe not that impressive as only 5% but I've not seen an inlet system do better.

Thats not why I'd buy the kinsler system though.

The reason is that it was a fully adjustable and no backlash beautifully engineered setup.

I could just sit next to the car a watch the throttles being tweaked even if the engine wasn't running.

I imagine they would be hair trigger postive connections when driving. smile

It really doesnt need to be even more snappy! I'm just curious, i was impressed with the gains i got anyway, but agree they do look sexual. smile

The Mosler guys used the LS6 with a standard intake, then moved to the Kinslers, then moved to the LS7. An LS7 should be 505bhp stock. Remap the ECU with no regard for emmissions and that will go up. Slap some Kinslers on and I'd expect it to go up again, by quite a margin. I'd expect a remap to be required again though.

You're right about the Kinsler's smoooth throttle action etc - they are beautifully made.

As an aside, the throttle response on mine with the FAST intake is very snappy. The tiniest touch of the throttle pedal bangs the revs up. Mind you, I have a different cam and a tiny 5.5" clutch and flywheel which won't help. Fortunately we do rolling starts!
