4.5 litre turbo crown is running
|
Mon, 14 July 2003 05:52
|
 |
After 9 months of turbo conversion the Crown rumbled into life again. should be 3-4 weeks till dyno time. Time to shred that poor old f seris diff with 650+nm. I am feeling sorry for the trans in advance-I don't expect it to last too long.......(and It's only idling in the garage thus far)
The big TO4 spins at the slightest blip of the gas. the response should be good.....
Woohooo. It's alive again.

Take some pics of it on the first spin and then take some of the contents of the F-series diff being poured out afterwards!

Pictures and vids will be coming in the next few days-I just need to get my hands on the equipment. Interestingly, at Idle (a whole 650 rpm) with a 6 inch exhaust stack off the turbo and nothing else, it's far less noisy than the old animal 5M was with a full exhaust.
Dyno day is pencilled in as august 8. I'll definately have the camera there!

Here are some pictures of the Crown in almost ready to drive stage, although missing in the pictures is the intercooler, intercooler piping and thermos (now fitted).
It's now ready to drive actually and I crawled around the block last night to check the trans (Supra 4 spd) was shifting. With the modded valve body it was neck snapping from 1st to 2nd at only 15 km/h with almost no throttle. I'm a bit worried about how violent it'll be under power! Feels good though! More testing this week!
Anyway-here are the pics.

Norbie-Dunno when we'd get a head to head chance-you're in QLD yes? Maybe I'll venture to the nats next year. Otherwise I'll post a timecard when it comes to hand. I trust the 2J is treating you well!!
Note-It'll have to be on a very flat and straight road. It used to handle like a tractor-now it's more remenicent of a combine harvester.....

Yes, you should definitely bring it to the nationals! The 2JZ is going great; it's run a 12.49 recently, so that's the number to beat. I have a feeling you won't be lacking in the horsepower department, so as long as you can get the power down you won't have any problem beating that number.

Awesome, should be good to see the numbers. It is fantastic to hear of a project derived from original ideas!
I have not seen that model of crown before, they look very very similar (apart from the location of the front lights??) to an MX23 MarkII...

Yeah-I'll be doing a tech article for the Classicrown site so I'll give you a copy too Ed. I'm going to get a video camera for the dyno and also put some footage on a CD for GT-maybe I'll try and upload it as well so everyone can have a gander as well.
Judgement day is nearly upon me! -only 9 days till the dyno (18 months in the making!)

Nice thing!
I've always wondered about those engines. Do you have specs etc, such as weight, (It's cast-iron block/alloy head, right?), bottom-end strength etc etc? Obviously, I'm a bit "biased" toward the 1UZs but I reckon one of those big 6s would be quite reasonable...I was thinking recently that one of those, done like GTs 2JZ and chucked in a Cressida wouldn't be too bad! (At least there would be room for extractors etc).
Anyway, very nice! Can't wait to see the numbers...and maybe a nice vid of you and Norbie's beast going head-to-head down the 1/4...

230 from a turbo 4.5 litre engine, are you serious? Even if you're talking kilowatts, that's WAY too low!

Biased, I'm not too sure about the weight of the motor (didn't have a chance to weigh it before installing) but all I can say is HEAVY (and LONG). Fitting it into the crown has taken the handling from awful to a bit worse than awful-overall it was bad, and still is, but I'd think that it would really ruin a Cressida. I reckon your 1UZ is a much better option for a cressida.
yep-cast iron block/alloy head
4 valve per cyl
shim over bucket arrangement
9.0:1 comp
100mm bore
95mm stroke
internal oil cooler (by coolant circuit)
Oil cooled pistons (oil squirters-ala 1J/2J)
oil scrapers/windage baffle tray (to stop oil slopping around during 4wd adventures-but will help it make a bit more power when I start to push it)
As far as strength goes, CAPA in the riverland who do supercharger kits for the 1FZ reckoned they were very strong indeed. The advice was not to bother revving it more than 6000 and make power with boost. They report 300 FWKW on about 10 psi.
As far as boost goes-I don't know yet-I'm intendng to run as far as the injectors (upped rail pressure to 60-65psi) will go. (I'm expecting to run 12-15 pis at this time)
As for expected power-I'm guessing 250 at least-but as we all know-until it's on there it's just pie in the sky!

Good stuff! True, the 1U is in some respects a better option due it's strength, reliability and light weight (all reasons why I chose it) but, given that the 1FZ has the first 2 criteria covered, plus it has SIZE, I was particularly interested in the weight differential between one of those and, say, one of the other common Cressida 6-cyl swap options, given that the 7M and 1/2JZs are all cast-iron/alloy-head combos...
As for the handling issues, how do plan on rectifying those? (If, indeed, you are planning to )
FWIW, I just had the suspension replaced in the Cressida yesterday - Hello Kings springs/Koni shocks struts/new bushes - Good-bye $$$... Anyway, I'll be very keen to see just how much of a difference it all makes to the handling when I "test" it at Wakefield park in August

 Handling

Fri, 01 August 2003 00:04

I'm intending to do a bit to the suspension actually to try and rectify things. At the rear I'm going for an XB or similar swaybar and a Watts linkage to go on the borg warner diff that's going in. Also at the rear the new skyline GTS LSD has disc brakes. At the front I'll go for two stock swaybars, nolathane bits, rack and pinion steering and XB brake assembly (stub axle assembly goes straight on. I can then just bolt on all of the off the shelf XB brake upgrade stuff)
AND, I'm going to finally bow to peer pressure and get a different steering wheel. Current stock one really belongs on a bus.
Once all that is done, it may be okay. Considering you can get XB's and the like to handle okay with a bit of work-it should be possible. I hope.

Boost is GO! Had some low speed test laps around the block on the weekend and for the first time it was generating boost. It wouldn't generate more than 1 psi in second before starting to spin-so I have no idea how much the system is set to-have to wait till Friday on the dyno. The motor behaved perfectly. It seems to start to generate boost (quickly) at 1100-1200 or so and makes the angry pigeon noise when being free-revved (no BOV yet). No temp woes at all, no funny noises. The only hitches were when it popped a couple of intercooler pipes that I had neglected to tighten. Looks like the conversion has been a success! It is quite clear that the 3.9 diff ratio needs to go as 1st is a waste of time. I need to up the ratio so 1st is the same as 2nd is now. One annoying thing came to light on Sunday though. The trans was a bit of an unknown quantity. Prior to the conversion the trans was shifting a bit funny, but it was put down to the valvebody. Now with a new modified valve body it is behaving in exactly the same way-but now it doesn't want to hold in third either. I knew that at some time I'd need to have the trans done-but it has now been pushed forward. It's annoying but it means that when I go to the track I won't be wondering if it'll hold as it will be all new. I'll probably have the extra cultchpacks put in second and all the friction material upgraded-basically then it will be a full race box (ooh ahh). It does mean the whole shooting match has to come out again though. Irritating-but it means I'll have peace of mind when I venture out onto the track.
As for the dyno, I'll still have it done on Friday, but it'll be done in 2nd gear. I'm going to take the McReary race tyres for traction on the rollers-the tractive effort in second is going to be brutal. Following the dyno session, the engine/gbox will be coming out to do the trans-and it'll also give me a chance to get few small jobs done to make the conversion perfect.
-Key theme music here
'The Neverending Story, la la laa, la la laa, la la laa............'
Sean
PS
As for the size of the car-they weigh in at 1310 kg according to the manual. With the bigger motor, all the associated crap, the auto trans and fluids I'd think around the 1400 kg mark. As for dimensions, about VK commodore size.

Yep. On advice from the dyno operator, the session has been postoned. At the moment the trans is acting up, slipping in 3rd gear. The word is that 2nd gear will give too high tractive effort, causing wheelspin and flashing out too quick for a good session. I'll have the trans re-built in the next week or so to full race spec. That means I'll have no unknown quantities in the driveline. It's a pain, but will mean a fully sorted driveline for the strip.
Bugger. Yet more money.

It's coming. I only just got the engine hoist from my mate on sunday as he has been in hospital with pneumonia. I got the engine/trans assembly back in last night and now have to bolt all the manifolds and stuff back on.
Soon. It'll be ready soon. (the most over used phrase in the modifiers phrase book)
