LS1-LS2 Conversion

Havent looked at putting one into a HK, but did look at doing it to a landcruiser. The conversion to be legal in vic was going to be atleast 10 grand with motor adapters wiring etc.

Also if your interested in a near new (7000k's) LS1 out of a VZ SS let me know as we are selling one. Located in Vic.

I am interested in doing a similar engine conversion in my HT, i still havent really made up my mind what i want to achieve with it yet, just dreaming really LOL.

Theres a bloke here on old holden who looks to have put an LS7 (going off his username) in an HG or something. Just saw the pics, but i dont think there was any info with his post.

LS1 HK conversion kit

There was a write up in street machine a couple of years ago when this company were building the conversion kits so there might be the information you want. If you don't have any SM back issues to flick through they are only a phone call away.

Here is a link for what you need

The sump will be a real

The sump will be a real bitch as they're integral in the LS1-LS2 motors.

I remember some guy who put one in a HG ute and had no end of trouble, ended up heavily modifying the sump to make it all fit.

I also remember some place selling sumps to suit for about a grand....peh..bugger that.

Mate how did you go with the conversion im having trouble.

ht ls1

I bought akit off cae sump pipes engine mounts gear box xmember and rack and pinion steering. Everything looked good until I got to the steering, doesn't fit hits the sump. Phoned them a number of times and all they can say is that they have sold 100's of kits and never had a problem. So it's up to me to modife it , which I'm pissed off because thats why I spent 4 grand so I wouldn't have any trouble.

HT Premier LS1

I have done it. I have an LS1 fitted to my HT Premier.
TH350 Trans, 3500 Hi Stall, shortened 9 inch with LSD.
The LS1 was built from scratch to suit me adding a to4z turbo.
Its all in and running and i can drive it altho it does need a really good tune.

It was not easy in the slightest. Sump can be purchased from "CRS" or you can modify a VE sump if you know what your doing. Steering we made up using the kit from "V6 Conversions" and used a VK and VN Shaft to make it work. Next is fuel issue. an LS1 requires a return line so not only do you need to beef up the fuel pump but you will need to run a return fuel line.
I have kept mine fuel injected as im not a fan of carby (even tho this sacrifices some HP)

I would say that if i was to do it all over again i would not go LS1. I would for easily the same amount of money build a supercharged small block Chev.

If you want to know more just send me an email
