Lola - Ke55 4a-gze

[Tiger]

That would be a constant setup... no restrictions... that's probably the only thing.

Hmmmm.... surely theres a way around it.

[ancullen]

Biggo - yep, still a T50. As I'm not trying to do any clutch kicks or any other silly bloody drift techniques (damn I hate how destructive drifting is), I figure i should be okay. Plus I've only got about 180hp max at the motor currently. When I've got a megabeast of a 7A-GTE or even just the 4A-GTE I might have some issues, but plenty of people seem to have done it using just the T50. The W5x just seems way too heavy.

 

Tiger - no way around the restrictions unfortunately - not unless I want to be disqualified. Worse than having a air restrictor is the fact that I'll have to run it the motor in a car that weighs at least 1225kg - unless I want to use it in a FWD car in which case my minimum weight only has to be 1175kg. Still very heavy, but not quite as bad. If I go for naturally aspirated my minimum weight is only 1015kg RWD, or 965kg FWD. An AE92 would be a very cool under-1600 racecar I think.

[love ke70]

:( those restrictions are nuts. whats their demographic? you could make a bloody falcadore weigh less than that :D

[ancullen]

What's their demographic??? Not sure what you mean by that, but the minimum weight of 1225kg is for any RWD car competing in the 2001-3000cc class. This is what my Corolla would compete in as any car with forced induction has a multiplier put on it's engine capacity of 1.7. Therefore a 4A-GE (1587cc) with a turbo or blower ends up with an effective capacity of 2698cc. A 7A-motor (1762cc) with forced induction comes to 2995cc. You're actually allowed to exceed your class limit by 2%, so I could actually take the engine out to up to 1800cc (3060cc with turbo) and still be within the same class. But I wouldn't bother unless I needed a rebuild with new pistons (81.5mm bore pistons).

[love ke70]

what i was meaning was are they trying to get bogans in their fowlcoons etc in there. just thinking how ludicrously heavy your car has to be. but if its for 2001-3000 cc i think its crazy heavy.

ke55 with the 4agze and tuugher diff but stripped interior would way all of what, 900 kg?

and raceflo's ae86 with 3sgte and tuff as guts everything comes in under 800 kg. (yes its had alot of work done to get it this light) but all I'm tryna say is i think the restrictions are very "large car" friendly.

 

how would you go about bumping up the ke55's weight to meet the restrictions?

[ancullen]

I think a roll cage would add a fair bit of weight - but I doubt it would be another 325kg. I'd have to see how much the suspension & brake setup I want for it would change the weight, then if I was still under, I'd add ballast. By adding ballast, I could work out exactly where I need it to balance out the car best and to keep the weight as low as possible in the car.

 

And I don't have a tougher diff in my KE55. It's just the standard Borg-Warner from the auto KE55 (4.3:1 ratio instead of 4.111:1), and it's been welded into a locked diff. The welding wouldn't add very much weight.

 

As for an AE86, I've seen where a full range of fibreglass panels is available, so I'd investigate the Group 3J rules to find out if they're legal, then use those if I could. It would get the weight right down, minimising weight at the top of the car, and the ballast would be put as low as possible, meaning it should have excellent handling.

[ancullen]

I went and checked out an AE86. It's a bit worse than I expected, with a very rusty floor on the driver's side (I'll have to weld a sheet of metal over that), rust in the rear left hand quarter, rust in the driver's A pillar, and who knows where else. I did know that it wouldn't come with a bonnet, front bumper, or windscreen though, so that wasn't a shock.

 

It did have more interior bits than expected though, which is a plus. And the diff is already welded and the rear suspension is upgraded somewhat (Sierra shocks & Commodore springs I believe). The seller wants $1,000 for it, so I think I'll go ahead with it as the engine and gearbox would almost cover that, plus I get an AE86 with some potential thrown into the deal. It will take me quite a while to get it to a state where I'd be prepared to drive it though, so I'll have to talk to my father-in-law to see how long he'll put up with storing it for. The engine is the most important bit to me though, as it has a RWD intake manifold with TVIS removed and a bigport head. I need both of these for when I start to get serious about engine mods, and I can still end up with two pretty good motors:

 

MOTOR A

Bigport head

8.9:1 compression forged pistons

RWD intake manifold

Turbo

300+hp

 

MOTOR B

Smallport head

9.4:1 compression non-forged pistons

SC12 & standard intake manifold

Choice of two sets of extractors

180+hp

 

So once I've sold some more KE55 parts it looks like I'm buying an 86. WOO-HOO!!! I've only wanted one since before I got my licence (about six years ago) - BEFORE Initial D, unlike some pretenders :P.

Check out what I JUST picked up:

 

 

That's right. A set of Whiteline swaybars, plus an almost complete set of bushes for my car. Big thanks to Troy (Boofis) for selling me these, plus his help with all the dicking around we got from the courier company.

 

Now I just have to install these and my Commodore brake pads (I will get around to doing them eventually) and hopefully at the next race meet (end of July) I can take a second or two off my lap time.

 

As for the Sprinter, I think that when I buy it it will be a long term project, as I want to properly remove any and all rust, then paint the body up nicely. Once that's done I don't know if I'll drop the 4A-GZE smallport straight in, or leave the current bigport 4A-GE in there for the time being. As the rear suspension has already been upgraded on the car, I'd check out what the front is like, and look into changing that. It'd be very tempting to try and get the car into a registerable state and keep the KE55 as the racecar for a couple of years. Damn I hate decisions.

[love ke70]

me thinks having two cars you will sacrifice one for the other and vice versa and never end up with the best product you could.

 

go the 55! its unique!

[ancullen]

Meh, the KE55 will eventually go. The AE86 will be the main project, and will be done properly this time. The '55 is just for some fun until the point when the '86 is ready to rock. :P

[Biggo]

Good work mate!

 

Love the gear you just bought :S me wants!

 

id say go with the bigport, but thats me being me and i have some good plans which I'm pretty sure will work. Ill get in touch some time with so we can discuss them.

 

HOOLAAYYY for a race spec AE86 :P

[ancullen]

I'll be using the bigport head for my mega-motor, but the bigport bottom end with smallport head may eventually end up being worked into a nice N/A motor as I'll ditch the supercharger later on down the track, if I even use it in the first place. I may just end up swapping the heads between motors, as the bigport still has the standard Toyota ECU, so I'll be limited in my modifications until I get another aftermarket ECU - long way away.

[ancullen]

COMING SOON:

 

 

Just bought these for $220 (including postage). Thanks to Taz Rx for pointing them out to me. Now I'll just have to get my hands on some brake pads (Bendix Ultimates, expensive, but good), Corona struts, AE92 springs, AE82 (I think) shocsk, Sigma LCA's, and a master cylinder from an RZN167 Hilux. Or I might just get the Hilux master cylinder and Peugeot discs and see if I can fit them on my current struts, thereby being able to save money to afford the suspension bits.

[ancullen]

Oh yeah, and as I've got a set of Bendix Ultimate pads to suit my current front brakes, which I've never used, I might try and find a way to use the current front brakes on the rear.

 

The only problem will be finding a suitable handbrake setup. However, the current model Corolla has a handbrake setup contained within the rear discs, or so I believe. So I might try and find a RWD car with a similar setup and the right stud pattern and work from there.

[ancullen]

Oh yeah, and because I forgot to mention before, I won't be buying the AE86 as the owner has retracted the sale. Oh well, superfast KE55 here I come. As I'm now starting to find so many good parts for the KE55, I may as well stick with the original plan of building the fastest KE55 I can, although now the plan includes a turbo instead of a blower.
