LS Engine Problems

[Mjpmark]

Well to summarise, we have decided to change the cam.
It appears without huge expense and time it is not possible to get the engine through IVA emmissions tests. I feel as though i have been severly ripped off by ** ***** *****. They knew this engine was going into my NEW UNREGISTERED GTR, and said nothing of known problem re emmisions. Now i have missed the IVA at my cost, must pay for the engine to be removed and now modified back to a cheaper version with less power. So i guess i technically have the most expensive underpowered ls3/480 possible to buy anywhere!!!

The emails i have recieved behind the scenes have been huge in detail and quantity, it seems im not the first or only person having problems like these with said supplier.

I must stress to anyone thinking of buying an engine and ecu or either from the above company please contact a few of us on here, there seems to be horror stories arising from everywhere.

Please do not waste your money here and use an alternative.

Im sure many have had a decent crate engine package from them, however a company is only measured by its back up service. There is none!

It was increased inlet lift Capt C not more duration....

Craig Im certain that cam can be made to work but to allow the stock ecu/FBW combo to be used I considered a cam with increased inlet-bias would be a solution. Having tried this with success (Mr Hodge) it proved what confusion is caused in the common inlet at low rpm when running an upgraded cam. Just by smoothing out the inlet pulses a little at low rpm allows use of the stock GM components and the software seems to cope well!

yes it can be made to run smooth, reliable and with good power results and it can be made IVA emission compliant with the right approach....as i have proven.......but i cant really comment if the two statements can be at the same time "if you get my drift" :-)

mark good luck with whatever way you go....

Chaps - please note and adhere to the name and shame rules of PH. Sorry to be a bore (and I feel your pain Mark), but they're there for a reason.

[Mjpmark]

Sorry mate, understood.

Stig,

I know we have to stick by the rules but this company is very good a promising and then not delivering. My advice would be to buy the crate engine and source everything from other suppliers. Parts out of this world performance (see I did not name them)

maybe a better way to put it is dont buy a Ls376/480 engine from anyone with stock ecu as you aint going anywhere unless you use the developed IVA map for this variant and a piggy back ecu. It then runs a developed road map.

Mark, are you going back to standard cam or will you taking advantage of Capt Wardles vast knowledge and running with an upgrade?

[Mjpmark]

Hi Dave

Awaiting a price for a nice Cam, so will weigh it up then.
To be fair im losing motivation now, the road has been a long one, and this final issue has worn me down, to say ive the idea of Ultima ownership has lost its appeal is an understatment.

Nothing a quick drive wont sort out but im sure you know what i mean.

You forget why you started building them after a while, just need to enjoy the ownership part for a while i think.

Oh and a word of recommendation, stay standard!!!!!!!
Modifications are hassle!

On my side I guess I used the most expensive LS7 way.
Thanks to TRMV8 or Tim Madge...

^ do the name n shame rules only apply to PH sponsors? TRM-Co seems to get lots of ongoing negative mention.

Well, when you hear all the talk of scams by certain people, IMO it is normal to make others aware of the unrecommended attitudes of these thieves and bas Ask Budala, I'm sure he can talk for hours about a certain person who "screwed" him of a sizable amount of cash

I regret so much ! I should have retain your proposition Mike ...

I paid £18,565 for an uncomplete engine and wait 6 months to get it !

And still waiting for gearbox, clutch, headers, etc, etc...

As I said Guy, I feel Mark's pain and wouldn't want anyone else to have the same grief. However, the Haymarket legal bods put the name and shame rules in for a reason and as such, I'm afraid we all have to abide by them.

Easy enough to PM the OP for details.

They apply to all - can you link to specifics?

I am wondering how this rule sits with the fact that there are many review sites out there that specifically carry the good and the downright bad experiences of customers for even the biggest companies. For example www.reviewcentre.com and provided the text is not abusive, they allow even very negative comments.

Perhaps we should ask for a similar service within PH, thus not clogging up the main forums, but when needed refer to the 'PH Review forum'???? I recon that would be an excellent addition to this site, and help those like me that are looking for good suppliers and service providers whilst avoiding the worst of the bunch????


Stig? Good idea, or good idea?

we have had issues with cams in ls3 motors that would run ok in ls1,2s we used a cam from thunder racing in the states there ls3 blower cam , it has a good split on it and qorks very well they do lots of cams now , not just fitting old spec ls2 cams in square port heads worth a look,

[V8Dom]

I dont normally express me opion nowadays, however I feel if someone is ripping-off one of us we should all know about it and he should be publically shamed.

We all make mistakes in business but should own up to them and rectify them. If we cant we should not do business. We now live in a society where the bad buys have more rights than the good guys and its terrible. I say if someone breaks into my house I should be able to shoot them as they should bloody be there to start with and if a company is constantly stealing our hard earned money then name and shame them until they go out of business. Serves them right.

Stig I fully understand the position you are in as I do work for Haymarket however if it is ??a common problems we should stand up and fight..

I've got the bog standard LS3 engine in my 2 ton VXR8 and it shifts - I cant imagine what it would be like in a car weighing half as much. In stock form it red lines around 6500 rpm, so hardly a slug.
Surely changing the cam is just narrowing the torque curve and pushing the peak bhp higher up? Resulting in an engine that is less happy pootling around town.
