Thread: Pinning Liners in a 4.6

Do you want a 3.9? My son has one. If he wants to part with it is something only he knows. I wanted it to put in my FIAT, but that's probably not going to happen.

PM him: C.tins is his username.

summary: same price, but ls1 double the power

That was my concern with a 4.6 If I went that way then I would possibly have to do the trans and diffs ect, what then started out as a simple engine refresh becomes vrry costly.

from TRS:

Hi
We can help with the following
4l stepped liner short $4100 4.6l stepped liner short $5500 the usual labor cost is around $2000 to remove & refit
Regards Phil


$5500 + $2000 = $7500


4.6 168kw 380Nm
ls1 225kw 460Nm

+30% power
+20% torque
thats the max figure.
the power band fatter just above idle, yet linear as the rpm rise.


the ls1 plan im putting together comes to $9500

fuel systems, cooling system, air-conditioning are easy to do
cruise control, dont have it in the first place

in sa engineering would be easy as its a rigid chassis, similar weight engine, and brakes are vented. wouldnt need an eng cert.

you mentioned a new 4.6 for 4-4.5k, but thats not top hatted, so add 1k+ for that.

Fitted? Would that figure also apply to a P38? The ZF should take the torque, shouldn't it? I'm asking 'cos I know where there's a cheap P38. Although the budget won't stretch that far just at the moment, I was very impressed by the car I mentioned.

yes fitted.
drive in, drive out.

i have a R380, so i cant comment on the P38 or the ZF.

yeah, hence why i was looking at other options (ls1)
i emailed them cause i wanted a baseline/comparison.

from what i've read, the crate engine still can suffer from slipped liners and/or cracked block. im pretty sure my 4.0 is faulty. i could fix it, but i dont like spending money and having the same as what i had before. if i spend money, i want something better. 4.6 is better but not cost effective to bulletproof. but ls1 is just so much better in almost every respect. power and torque both near idle and up high, better economy.


stock LS1 one.

i see we have moved on considerably from the original question about Pinning the liners in a 4.6...
