Default LQ4 MS3 ls6 - 75 shot. Timing??

Ok I'm running a 75hp wet shot on my lq4 240sx
I got a ms3 cam kit from tsp
TR6 plugs
HP tuners.
what timing do you think would be a safe place to set the timing?
or at least start checking the plugs at?

Swap plugs would be the first thing. Start with a br7ef plugs. NGK #3346.

Where is your timing at now? I would probably pull 5* from NA and start there. Why only 75hp on a lq4? Just curious why you chose the smaller shot.

I just got the system on there and it cam with 75-125 shot. I wanna run the 150 but just incase theres a mess up i would rather it be on the 75.
I swapped to the br7's and gapped them to .030, and I'm at 26* at wot but my afr's are still like 10.9:1

I have the jets for the 100 and 125 shot should i just pull more timing and go for it?

Oh yeah its at 26* from 3200 to the end of the map on htp. The NA tune was 32*

On a 75 Shot??? At the coldest stick in a Br6 plug.. I would pull 3* at most with that little of a shot, Its hardly even tickling it at that point.. And start ramping the timing in 1* at a time.. To be completely honest, i would prolly leave the TR6 in it..

It feels awesome but still rich as ****. Low 10's afr's while spraying.

I dont doubt it man, You have a Br7 in it with 8* pulled out on a 125.. That is crazy talk! Just curious why u were running 32* of total timing on motor? Most i have ever ran on a LS was 30* Total on motor.. If it were me, U have 24* total on the Bottle? I would put it at 23-24* total with a Br6 in it and check the plugs.. If u dont know what u are reading on the plugs then, do what i stated above and log Knock and start pulling fuel out of the bit till u get the Wideband reading about 11.5 -11.8afr..

The lq4 has a lower compression ratio so it needs a little more timing to make power with this cam setup
