Having sold most of the driveline , a few pics of the LS1 conversion are in order . Car will be carby fed as its a track only vehicle these days and suits my requirements , im using the factory ignition system for spark and the T56 for the gearchanges . Enter ex VX LS1 and six speed . Power steer / aircon removed . It was purchased without manifold / injection / loom . Fitting one of these Dale from CHE has supplied me with an ignition only loom which should arrive anyday now . T56 is a big gearbox especially compared to the out going W57 supra box . Supra weighed 48 kg's and T56 72 kg's but the flywheel used in the supra was the std holden 308 one and wieghed 15kg! . LS1 is far lighter so maybe only a 15kg difference at the end . Next is sump / new clutch / starter conversion and extractors . adam Some original photos have not been recovered yet.

great project keep us updated show us a pic of ur car

Couple of pics Has another set of rims on it at the moment in my bid to reduce unsprung weight adam Some original photos have not been recovered yet.

farkin sick champ

how did you go with the clearance with the extractor on the drive side??

Ive got a set of 4-2-1's coming from CAE which are off the shelf items , they'll be here next week ready for the final fitment of engine/ trans . High Energy have come to the party also with a circuit spec pan to fit gen3 into VB-VS commo's , just finalising some details as my car is being used for some R&D . adam

Finally, someone showing some real engineering! Well done and keep us all updated.

does cutting the bungs off the gearbox end the chances of getting an engineer's cert?

No , their bungs which are used for commo / corvette and what ever else . Remember if going to register it properly in a legal road car the cost of the speedo conversion alone as a silly price plus plenty of little traps to get caught out on . Getting everything in is quite a simple job , ive only put about 10 hours into it off and on and its sitting in the bay complete with exhaust / tailshaft / shifter finished . Need to finish fuel and sort out the ignition plus water hoses and all the little things that take time ( which i dont have) . adam

Updates !! . No its not running yet , but i have some shiney new parts . Ive been dealing a bit with high enrgy regarding a circuit spec sump and as they are keen to fit their new LS1 sump into the older shape commo's a deal was struck up for some R & D . New sump and old sump baffle and trap doors side pic The shear size of the sump extension had me worried as the std sump is a nice tight fit but didnt leave a whole lot of room for a larger unit and sure enough it foweled on the x members where the supports are so i gave it a little clearencing . Next on the list was the extractors , as i mentioned before they are an off the shelf item and i decided to go the 4-2-1's as space is so tight as much room is required as possible. With these pipes you have to relocate the starter motor as its in the way , ive now seen one done in a VS with leaving the factory starter and custom making extractors but at close to 3K its cheaper to just go with the conversion way . Next is final fitting and adjusting and then start on fuel / ignition etc. adam Few more parts fitted over the weekend and just waiting to get the extractors back from being HPC coated . The pipes required some creative bending with an oxy to help clear the floor and the drivers side rail , the arent a bolt in but are close enough for a back yarder to fiddle with them to clear most problems. The do sit pretty much on top of the crank angle sensor so some heat wrapping of the loom is a must along with a the starter motor wires . As you can see from the pics that with the manifold on it sits quite high requiring a hole in the bonnet and scoop which isnt a problem for me as its a track car anyway , the factory EFI system wouldnt have any dramas clearing bonnet heights . I do have a 1 inch spacer fitted in those pics but even without it it would be a close call . adam Should be a runner in a few weeks as im waiting on parts a few little things to finish it.

wow mate the engine conversion seems to be going well if you can try and get a video of her? Some original photos have not been recovered yet.

Comin together well mate good job!

nice stuff

Looking good man, good inspiration, since il be getting my ls1 when i get the $$

Couple of finished bay shots Dale sent down a modified loom for me to get it ready to go and withing a few pumps of the holley it fired into life and settled to a nice idle , its missing a TPS ( fitting this week) so its a little fluffy to drive and im only putting around anyways . Its had a decent miss/back fire under light to medium throttle openings but seems to clear up the more i drive it and im really not worried untill the last sensor is wired up. Its pretty exciting getting it to fire for the first time , always the concern of what ive forgot to do ! . Within a week or two it will hit the dyno and ill get it sorted , btw stock LS1's dont really sound that nice straight out of the extractors . Everything works on new dash Rev tach needs to be set to 4 cyl mode to work with the LS1 puter, hence the aftermarket job. Havent got the car above 85 degrees to turn on the thermo yet as i think they go on at 90?? . Gearshift is spot on and hydraulic clutch is way to light , im used to cable plus heavy clutch. Little things to do are fit bonnet vent / scoop ( proberly walky one ) lower engine another 7mm ( easy done , can adjust engine mount) track down small slave cylinder leak ( dammmmmm ) profit?? adam Some original photos have not been recovered yet.

Thats nice man really like what you did with the dash, and its looking really good overall

Any updates mate! good stuff

wow that thing is a beast great work Some original photos have not been recovered yet.

post more photos mate this is really interesting.....

Sorry guys , forgot about this thread . Cars been finished , dynoed at 215 rwkw with a 650dp which was found to be too small . Hp holley 750 fitted 230rwkw and excellent drivability . Heres that last few reports. Finished setting up the TPS switch and the difference is impressive , engines like timing!! . Another big thanks to dale (castlehillexhaust) for some questions answered on saturday regarding the TPS . The switch is from a 2.6 magna and is faily compact 3 wire switch which isnt hard to adapt to the Holley carby , quickly set it to read .50 amp on idle and away we go . Quick spin around the block and while it doesnt turn the tyres of idle like the old 5.0 it really gets going up top and loves a rev . Its strong(ish) low in the rev range for a LS1 but thats due to the VL waying stuff all , should be around 1190kg when finished. Its also very responsive with the carb , revs up quicker than the EFI version does . Finished , but fuel lines will be re made this week for more clearence . finished car , looks road legal kinda Things to complete before dyno . Ive had to re wire the thermos as its a negative trigger from the computer so still need to check if it works. Car doesnt want to idle for over 30 secs , it just dies slowly . Its timing related and ive adjusted the TPS correctly so ill have a look on the dyno using VCM suite to see whats the biz. Ive also managed to fry the alternator by accident , dam. I unplugged the wire that tells the dash light their isnt any voltage and it must have earthed on the body so alternater isnt charging and no dash light at all . Most likely the regulator . adam Some original photos have not been recovered yet.
