I wonder if I should get some ice for the intercooler... :)

Luke - You bought Tim's AE82 Twinky then? Andrew - the 20v plastic cover can be removed to expose the metal cam cover that is underneath - might be worth investigating to get a completely different look to everyone else?

Just checked - 20v engine's all have oil squirters. They have the 42mm big end diameter and 20mm gudgeon pin diameter. The silvertop version has the same rods as the 4A-GZE, aside from the head, the only real difference is the pistons. Unless you intend to change the cams or valves, the 20v head is better than the 16v. The 16-valve's only have an advantage when you put in massive valves and cams. You will be able to get 200rwkw on standard 20v cams. Just buy my 20v, drop in your forged pistons (and rods if you feel the need), slap a turbo manifold & your GT28RS on the side, buy Stephen's plenum, and get an aftermarket ECU, and you'll straight away get AT LEAST 150rwkw. EDIT: BTW, $500 for a silvertop is a damn good price. If you want one from a wrecker from interstate, you'll be paying about $1,000 for just an engine, plus another few hundred for freight. You should be seriously considering it.

As soon as you put the different conrods and pistons in, won't you lose the oil squirters? If the silvertop comes with them, then just buy my silvertop and bigport and combine the bits together that you want. And don't even joke about me trying to rip you off - I kept telling you that you were being ripped off by the guy down south, but you wouldn't listen to me then. Since then I've offered you the bigport motor for only $200. No it doesn't have compression on two cylinders, but you're going to fix that by pulling it apart and rebuilding it anyway. The silvertop is $500 if you want it. It doesn't have an ECU, but you're welcome to do a compression test on it before committing to buying it. I do have someone else who wants the silvertop though, so it may be sold in the near future.

Yep, I'll be there.

Forged pistons - $800 Forged rods - $500 ARP bolts (full kit) - $400 New bearings (guess) - $300 New water pump - $200 Second hand 4A-GE - $300 Aftermarket ECU - $2,000 Tuning - $500 Turbo manifold - $500 TOTAL - $5,500 That's right, for about $5,500 you would have a tough-as-nails 4A-GTE which should do the 200rwkw you want. These prices are off the top of my head, and could be inaccurate. But it's like I suggested on Saturday - buy one of my 4A-GE's and put proper forged stuff inside it. It will be far stronger than a 4A-GZE and will make the power you want. DO EET!!!

Bowling was great fun - we should definitely do it again sometime. Here's the results - Tim, Anthony, and Ace (Matthew) were three mates I brought along. The others are Daven, Schmo (Joe), Ripof (Andrew - cause he got ripped off :(), and me - who else would it be? Results: First - Matthew - 344 Second - Daven - 310 Third - Tim - 242 Fourth - Adam - 229 Fifth - Anthony - 219 Sixth - Andrew - 177 Seventh - Dead Last - Flogged - Well and Truely Beaten - Joe - 152

I'm still hoping to have it ready for a track test this year. Whether it happens or not is another thing. :P I've just found out that half of my Sunday is unavailable to work on cars, and Saturday was already half taken. The rest will be taken up by working on the GT-Four. Hopefully sometime I get a chance to work on the TA22. All I want to do at this stage is take the 4A-GZE out of Lola and start test fitting it in the TA22 to make engine mounts. Then I'll need to weld plates to the front suspension towers so I can install the AE86 struts. There's not actually a real lot to do to make the car driveable.

All events are held on airstrips. Even though they try and pick the smoothest airstrip for the drags, there's generally still a fair bit of loose stuff on the launching point. As a result, the AWD's do pretty well, although that's generally only meant Devo in the GT-R. There was a Mazda6 MPS last year, but the guy held back a bit. The GT-Four should be done in time - I'm hoping to drop the motor out this weekend. Worst case scenario is I pay someone else to do it in the week before the Rejex. The clutch bits are in stock in Darwin, so it's not like I've got to wait on postage. And even if I go through an interstate company I can get the bits overnight.

There's no real rules about it, and as far as I know they still don't actually change anything if your car is modified. He's just worried because he knows I'm going to beat him on the drags this year. I've already beaten him when the GT-Four was on stock boost and he had street tyres on. With the GT-Four on high boost and a gravel launching surface, he's going to be destroyed. :P

And you're still suffering from the brain damage of banging your head against the window. 8| I've just been chatting with someone in the know, and a certain person is extremely pissed off that I put the GT-Four as unmodified on the Rejex Rally entry form. This person is also extreme concerned that I'm going to bring the Starlet, as he thinks I won't have the GT-Four ready in time. :) He's scared because the Starlet has beaten his car before, and the GT-Four will also be able to do it. Damn Honda drivers. :yak:

I should have taken the Starlet out and shown you how to go off road properly. :)

The Zook was fun. Would have been better if it had the clutch working properly. And had a 4A-GZE under the hood. :yak: But beggars can't be choosers. :)

Uh, you don't need to get drunk whenever you drink. It is possible to only have a couple of drinks so as to ensure that there's no alcohol in your system by the next day. I only would take a six pack of beer for myself, and I doubt I'd even drink that much.

Yep, that's the plan. RollaClub camping trip!!! We should take fishing rods and alcohol!!!

Anyone else interested in attending the Flying Fox Festival in Katherine this year? Details are as above, and we could do a bit of a cruise down, maybe take the old Highway down for some nice windy-ish roads. :) I'll be going in the GT-Four.

I'm definitely up for bowling this Saturday. Can do a cruise too, but the GT-Four won't be ready in time. I'm hoping to drop the motor out this weekend. :)

Yeah, that's the basic gist of it. The top is like a Macpherson strut, the bottom is the multi-link hybridy thing. I read just the other day that there's no coilover version available, which is weird since I've seen that both Tein and TRD have them.

My superstrut calipers are four piston, not pussy little two piston things. Superstrut suspension is a variation on the Macpherson strut which was created by Toyota. Can't recall exactly how it's different. Google 'superstrut' and I'm certain you'll find something. Or look it up on Wikipedia.

I've already got Superstrut calipers installed. :D Then again, I've already got Superstruts installed too. :yes: Fail. :D Boost is related to the size of the engine, and the volume of air being induced by said engine. A four cylinder four stroke 1.6L engine running at 7,000rpm will naturally suck in 5,600L of air per minute at 100% efficiency. An SC12 supercharger (1.2L volume) running at 1.25 times engine speed will be running at 8,750rpm when the engine is at 7,000rpm. At this speed, the supercharger will be creating 10,500L of air per minute (at 100% efficiency). Therefore when the engine is at 7,000rpm, the supercharger will be creating 4,900L more air than the engine is inducing. The air the engine would suck in on it's own is at atmospheric pressure (at sea level), therefore 1 bar (14.7psi). Therefore, the supercharged air is being compressed to 10,500/5,600 times atmospheric pressure. This means it will be pressurized to 1.87 bar (27.48psi). Boost pressures are recognised as the air pressure above atmospheric pressure, therefore the boost is 0.87bar (12.78psi). Therefore when a 4A-GZE is at 7,000rpm, an SC12 will give it up to 12.78psi of boost. It will actually be slightly more than this, as a 4A is 1.587L, not 1.6L, but you get the idea. If we now swap the SC12 for an SC14, we get the following: SC14 volume: 1,420cc Supercharger to crank speed ratio: 1.25 Air produced by SC14 @ 7,000rpm (engine): 12,425L Pressure ratio: 12,425/5,600 = 2.21 Boost: 1.21 bar (17.78psi) And just for arguments sake, here's what a Mazda twinscrew will do: Supercharger volume: 1,000cc Supercharger to crank speed ratio: 2.0 (this supercharger can do up to 15,000rpm) Air produced by supercharger @ 7,000rpm (engine): 14,000L Pressure ratio: 14,000/5,600 = 2.50 Boost: 1.50 bar (22.05psi) Please remember the above figures assume 100% efficiency for all components. If anything, the Mazda supercharger will make more boost than the SC14 as it's so much more efficient.

And just for reference, here is my dyno chart from when Lola went to Hi Tech: As you can see, even though it only peaks at 87rwkw, it's FAR smoother than the 143kW chart in the Toymods links. Also, just a thought - my boost is still limited to 10psi through the ABV. I would think that delimited (up to 12-13psi) it should come close to 100rwkw.

I'll stick to my conservative estimate of 150rwkw. Remember my engine only made 87rwkw on Hi Tech's dyno, so a 72% gain would seem big enough for the moment. As for the second last dyno reading, take a look at the other modifications the guy has made: Autronic SMC, 98-octane (mine was on 95), and custom 3" intake piping. I also don't understand how he can claim 9psi and such a high power figure. The whole point of going to an SC14 is to make more boost, not less. Anyway, with the twinscrew, I would hope to make 150rwkw on about 16-18psi. With the further modifications I have planned, including quad throttles, custom plenum and intake piping, 440cc injectors, bigport head with porting & polishing, big valves, and big cams, I would hope to get 200rwkw. Only time will tell though. And really I don't even need 200rwkw, as 150 would be HEAPS in the TA22.

As long as it does the job with my twinscrews. :yes: I want 150rwkw from a 4A-GZE, no turbos. Eventually I'd like to push towards 200rwkw, but that will require cams and head work. Probably will need a different plenum by then too. :D

Mmm, sounds like a good idea.

I thought Daniel actually managed a 12 at one point? Or was it he did a 13, but if he'd fixed the lack of grip he'd have done a 12?
