New Engine Build thread

Where exactly are you storing this engine? I'm slowly gathering anchilleries, but I need somewhere to build and store the block. I have no room in my garage I don't think building it in my room would be a very good idea. my dad suggested buying my own shed and building it in that, but I'm worreid about condesation over winter, screwing up the bores.

By the way, where did you get your engine mount thingy from?


:D

Thread resurrection :)

I've had all the bits sitting around for quite some time, just "waiting", which was probably the right move as no one else seems to have progressed things to completion with this setup. A couple are now getting close and we have an idea of what ECU to use.

So tomorrow I'm taking all the bits off to get the head properly ported, the engine balanced and assembled and a couple of other will jobs doing.

The spec will be:

GM 2.0 LSJ block
Saab turbo baffled sump
Standard forged rods
Saab Turbo Pistons
Under piston oil cooling jets
Saab Ported sand cast head
Supertech dual valve springs
Saab Sodium filled valves
Comp Blower Cams
Lightweight Flywheel
CMS Clutch
Balancer Shafts Removed
External trigger wheel
Alloy crank pulley
6 rib alternator pulley
VXT ECU transplant
z22YH Coil Pack
Walbro Fuel Pump
Pro Alloy Charge Cooler with dual pass mod
Chris Tullett 3" Exhaust
Chris Tullett 4-1 Manifold
Harrop TVS Supercharger
Porsche 68mm throttle body

The internals are good for 600bhp but I won't be running more than 400bhp, so fingers crossed it should be relatively unstressed.

The build will take a while and when it comes back it won't go straight in until others have the ECU all up and running, but at least it will be built and ready to go.

The bottom end is now rebuilt with a Courtenay Vectra V6 lightened flywheel fitted.

Saab sump (which replaces the LSJ one)

The oil pump internals, all looks good

The pistons refitted and the crank going in

Looks like a hell of a build! The VX does seem to have a big advantage over the Elise in terms of engine upgrades as the Honda & Audi conversions would cost more than my car is worth :(

Hoping that the Woodsport guys are successful with their V6 conversion but I got the impression that they would only want to do a few cars per year.

Any idea if anyone has tried to stick the GM lump into an Elise (apart from the rebadged version Lotus did ;))
 
Good effort :)

Interesting to see so many Saab parts used, I know the saab equivalents of a lot of GM engines are popular replacements because of the extra strength, but not seen individual components substituted before :)
 
Hmmm, think I might have to use the PC to look at these!

Lol

What sort of ruddy pictures are you uploading there. :p
 
Right then...

Please tell me you didn't just bolt the crank / rods in dry. :eek:
Can't see any assembly lube on there.
 
Forgot about the amazing pipework on this. Reckon you're going to hit the big 400?
 
Intake manifold threads tapped and enlarged for stronger M8 bolts, intake and exhaust ports enlarged.

the supertech double valve spring kit was fitted with the original saab valves

then the head was fitted to the block using a saab head gasket

then the saab cast roller rockers were fitted along with the hydraulic lifters and compcams blower camshafts

Saab cam sprockets were timed up:closedeyes:

Once the timing was triple checked the engine was sealed up with the oil pump and cam cover

Only a couple of blanking covers to go and it's finished :)
