If you read all posts, the motor is goin' in a lj torana!!!!! :roll:

i know of a lj with a sr20 in it... for a lj it is a good upgrade option as it gives you a bit of room to play with so your not cutting anything out or moving stuff like the steering box, and gives you room for a nice big intercooler too depends on what you want to do with the car, a sr would be better weight wise for circuit sort of stuff and has a lot of potential, but a lot of ppl would be bias towards a 6 including me Some original photos have not been recovered yet.

Jet pilot: is that vl the red one?

An old friend of mine did the rb20 conversion into a red mock up calais. I've Been in two rb20 powered VL's. Went pretty good on 14psi, just keeps revving, however doesnt really go anywhere unless you rev the **** out of it, and with a few people in the car it's a slug. Just doesnt have the torque. But it's definately bang for your buck.

Holden have already tried fitting 4 cylinders into a Commodore & Toranas (Sunbird) which were both big flops,these bigger Holdens are not specifically designed for a 4 cylinder engine anyway,they are designed for a medium to large 6 & v8 engine. As for an RB25,I think the bottom end torque will be too low as well,try a Toyota 1jgzte,which is a 2.5 litre but apparently has more the characteristics of a 3 litre VL down low due to its sequential turbo system which cuts in at very low revs.

To answer your question.........Sr20 would be the way to go in an LJ for my money........I base this decision purely on the fact it would sit further back in the engine bay. RB20's are still cheaper to buy...although the price difference seems to be reducing. But I would not put an SR into a VL when the RB20 bolts straight in and offers virtually the same Bang for your buck.......infact I would just turbo the RB30 in a VL...cheaper still Oh.......and Russell.......the VB - VL Commodores were specifically designed for 4cyls and straight 6's, as they were sold in europe from 1976 in this form (Opel Rekord/Commodore/Senator)....it was holden who shoehorned the V8's in Some original photos have not been recovered yet.

Any RB series engine is a natural choice for a vb-vl commodore as the engine cross-member is exchangable in all. To fit any RB series engine you need the VL engine and gearbox cross-members and the engine fits with no other mods needed. As for fitting either of the engines you suggested into an LJ, it's totally different. There is no easy way of installing one of the engines compared to the other. They are both foreign to the LJ engine bay, and as such will involve custom engine and gearbox mounts at the very least. As for the easiest to fit, I would pressume the sr20 is smaller and easier to fit then the rb20, but having not seen both side by side, I could not garentee it. With the need to at least fabricate the engine and gearbox mounts, your engine choices are increased. So why not choose a better, more powerfull engine. Get some measurements of your engine bay, and then see if you can find a suitable engine. Don't pick an engine based on what someone in the forums tell you, unless they have did the same conversion and can offer you some great advice. Pick the latest, biggest, and most powerfulest engine that meets your measurement requirements and you can afford to purchase. The list of engines around at import wreckers,etc, are huge.

Very sensible answer VK Turbo I put an SR20DET into my Bluebird.....but I reallly wanted the VG30T 1000 more cc's for power............1000 less $'s to buy. Problem was the licensing centre said 'No f*ckin way' My mate Alan owns the White LJ that was on the cover of street machine recently.....he shoehorned a TPI 350 in that!

why dont you go ca18 turbo.. cheap and just as good as sr20.. iron block is stronger than sr20's alloy.. just fit s15 t28, fmic, zoorst and it should go pretty damn well.

btw rb25 won't fit in the lj without some mucking around.
