Awesome day! f@$k you're gonna have to try hard to catch that fooking fook PHAT Rona, you may need to take some weight loss pills. Note to self - Padding for seats around the side. I reakon the track was pretty sweet, much better than the shit big cart track or that joke one on the highway to the sunny coast. We'll have to go back some time for sure.

get that racing fever going, will be an interesting race.

Thought I might post this good site of gearbox codes, crossmembers dimensions, etc. http://ourworld.compuserve.com/homepages/stepho/engcodes.htm

Trying to source a good box now :P Will post pix of the conversion, hopefully it fits in the tunnel ok. My mate has a 21 spline clutch and flywheel for the job. This housing runs a hydraulic clutch, so does anyone know which clucth master cylinder fits easiest in a Ke55 rolla. Forgot to add that this is a 9 bolt W5X pattern.

7 days to go! I hope it's not like the last time I went carting and I got the one with a clapped out motor. Must remember to take a can of octane booster :D

fook sorry guys :D Yeah I'm still keen as :y:

:jamie: I wish I'd thought to turn off english only data. But By the looks I reakon the GTE pins will be 20mm, hp /L it makes sense comparing it to the 4AGZE.

I googled till I couldn't google any more. There are hits with the right keywords, but they're about 10 posts away from each other in the messages. :jamie:

Cheers Jamie, Do you or anyone know the size of the 1g gudgeon pins? Thinking along the lines of 81mm 4AGZE pistons (20mm gudgeon) and 1G rods with that new piece of information.

Hells yes, when are you down

Will I make more torque with heavy skyline pisons and a 1.4 capacity? Being a turbo motor there's always downforce on the pistons, so it should hold together ok.

Yeah I was gonna get my mate to get me cost repco ones too. The Rb20det pistons aren't a direct fit. I was gonna get the bores machined a few mm's and get it sleeved at my mates workshop.

Lol, I blew my rings yesterday. Gonna slap whitey's 4K block in for a while, so It's time to rebuild the 5K for the blower. Been pricing some new ACL pistons too. Pretty good deal. I think I'm gonna keep as much capacity as possible over running the skyline pistons, the more gas to spin the turbo the better.

I'm keen as too, been so slack, I gotta meet a few more of you guys, any weekend if cool for me ;)

my mate tunes his lpg car with an EGO sensor from an efi rig. A small voltage is made by oxygen ore something. I'd say that most mixture meters would use an EGO sensor too. Either way you can just plug one into a multi-meter on voltage setting. If the mixture is sweet you get 0.5 V, lean under 0.5V, rich over 0.5V. Might be worth a shot, definitely a cheap experiment.

I have a 5K :D I want to keep that engine NA for my daily driver, and build a turbo weekend car. How much r u looking at to get your KE70 complianced with the 3sge in it? I've heard of some late model corona crossmembers that bolt into a Ke55 corolla that give you 2s engine mounts, apparently the gearbox crossmember bolts straight in too. I'm sure an engineer would like that. Does anyone know anywhere cheap to get engineering done, Brisbane area? I'm trying to do everything on the pov, I should be done with it and save up for a 3SGTE hey, stock a corolla would shred with that under the bonnet.

I've been thinking ... For the reliability of a turbo K motor, it'd be worth sticking in the single boost figures, as super jamie says, and I'd agree too, they aren't designed to be a forced motor. So, it probably isn't worth the cash to sleeve the motor, so would I be better off boring a 4K to 78mm ? I'm not sure what the maximum allowable bore of a 4K is, but loosing 1.5mm off each wall doesn't seem like too much to me, anyone?

It won't be a fixed boost car, it'll have an electic boost controller for 8 and 15 psi. Click the button fire show on demand past 8 grand :P

I think ... hope, the extra heat compensation of 15psi of boost will even up any head temperature issues. I haven't heard of much problems with LPG if you get a specific cam profile for the job. Vehicles that are dual fuel tend to have bigger troubles, and be less econmical than a fixed LPG car. The other thing I was thinking about was a prime button attached to a 5L tank of premium in the boot. Squirt in 50mls of petrol into the intake manifold before you turn the key might help dry starts., and I haven't heard about a system like this before Brad

Well if your up north in QLD above gladstone you will have pure propane in your car :P 112 octane. Down south of this point you will get a butane propane mix that is about 104 octane. People winge about dry fuels, but when you see a well configured LPG car you can tell there is no problem with it. On the sunshine coast a mate of mine has worked on a VL with an RB30et in it with a 650 cfm gas research carby making 450 hp at the treads on 16 psi :D Basically you turn your intake manifold into a refrigerator when you use LPG.

Ok, How much are you chasing for the T25?

Hey, I've started accumulating the bits and pieces for my turbo 5K. The plan is to use my 5K block, bore it out 0.5 - 1.5mm. Use some 78 internal, 81 - 82 exteranl, cast steel sleeves in the bores. I scored 4 rb20det pistons with 80k on em for 20 bucks! So that should work nice with some brass inserts to connects the rods. The pistons are 3.2 mm shorter than a 5K unit so I'm gonna deck the block 1mm and shave the head 1mm too, and use a 1mm copper head gasket with a double O-ring. I'll reconfigure the head a bit too. It should be about 1.4 L and 7.5 - 7.8 : 1 compression ratio after that. I plan not to rev it too hard so I'm gonna stick with standard 5K rods, though I might have them and the crank cryoforged. I'm gonna track down either a T25 or a T28BB turbo for the job, and make a custom manifold for it. Becasue of the space confinements I'm going to try to convert a water to air intercooler into a cooler inlet manifold, cosworth has a similar setup in some of there rally cars. I think it will be a complete custom case for the guts of the unit, because to flow effectively it will have to be fed at both ends. I'll be getting a 350CFM gas research carb and a convertor for the job of fueling it up. Down the track I might look at an ecu with methanol and water injection control. Now I gotta get the 500 bucks for a Ke20 coupe :down:

Alrighty then I think I'll have to ditch the 32/36 at some point. I'll try runny whitey's cam for a while, see what happens :P. Grimwolge, do you think the carby has something to do with the dead spot at 60 k's. How hard is it to get a pair of 40mm side draught webers running well? Are they as bad as the rumours of constanty needing to be tuned? Are twin su's a good option on a 5K? Just wondering too, where's a good place to source a double row timing chain?

I recently bought whitey of grimwolge to doner a few parts to my KE55 and a mates KE70. Well what I was wondering was what cam people have had the most success with a 5K. I'lll be running a 32/36 weber and extractors to begin with, using a 4K head, ported by my mate (thanks Mick). I'll be upgrading to a single 45mm DCOE carb at some point too. Whitey has a massive 88 - 42 cam, I don't think the 5K would be too happy about that as a streeter ... or should I wait and see now nice it rumbles. I'll be running 202 Holden H/D valve springs, because these were inteded for a stage 3, 6 cyl cam, should I only use the outer spring? They are bloody hard eh. How much should I get shaved off the head, will it up the compression much, is it worth it? Has anyone put in oversized valves in a 5K, I can get the machining cheap, what valves fit? Will it be worthwhile? I'm not sure of the biggest bottleneck up top in a K motor. Do I need to shim the oil pump to keep enough oil pressure up at top end? Cheers

sweet as, a nice capacity 4 turbo should be a bucket of joy :D Can't wait to see how your beast turns out :doublebird:
