| Newera Imports AE86 Project - 1st Trackday, Tsukuba.
Had a blast yesterday in my nearly completed Corolla AE86, It's 1st day out in Tsukuba along with 45 other cars out for a track day. This is the first time I've driven it in anger since completing most of the build for it. The engine’s a full blueprinted race unit prepared by Techno Pro Spirits with a 9,250 rpm rev limit running 11mm lift 304 degree cams, making around 200 genuine bhp from a 1.6 N/A. This engine proved itself to be very suited for track use, although I needed to keep it above 5,000 rpm to keep it from bogging down coming out of corners (It makes no usable power below 4,500 rpm). I found this is a car that rewards very committed driving and accuracy with the way the power’s applied. I have to say, this car was the most fun I've ever had on a track!! Most enjoyed the way the rear end would go light on downshifts combined with hard braking, as engine braking itself is fairly strong given that it’s running 11.5:1 compression ratio. Despite heeling and toeing perfectly, I found there would still be smoke off the back tyres entering corners, which also helped get the back to step out… Had to keep the engine on song mid corner to come out with full power, which often resulted with exits completely broadside & the engine screaming at full bore.. Grip was surprisingly strong, despite running Potenza RE-01R street tyres and not semi slicks, as the RX-7 does. It was only 2 seconds of the pace of the RX-7 (With which I got 2nd quickest lap of the day ). The AE86 would probably close the gap by a second or so, with semi slicks.. It's still too grippy for drifting, I think, although maybe with some rubbish tyres it'll become looser, but it certainly drifts. Then again, being more focussed on drifting than getting round the track as quick as possible, will make it go sideways better. I didn't try kicking the clutch or applying a dab of handbrake at all, as this was a grip driving day, not a drift practice and there were marshalls at most corners. Mine was the only car going sideways at all, as far as I saw whilst out there. The engine is seriously special. Useful power from 5,000 rpm and a rev limit of 9,250 rpm means I didn't have to change gears as often as other cars. I was chased hard by a stripped out Integra Type R DC2 which has 200cc more and much the same power and it wasn't catching me, even on corners. A couple of Skyline R32 GT-R's weren't gaining ground either lap after lap, but it's difficult to compare, as drivers may not have been all that committed. Was chasing one Celica GT-4 ST205 that was pushing hard but making up no ground. Sadly, he went wide on the long back chicane and then suddenly lost the back end right in front of me, before crossing my path and hitting the armco on the other side. The foam absorbed the impact and the kitty litter stopped it. I watched it bounce up in the air as it hit the foam. Real shame, that.. Felt really sorry for the poor guy. I kinda wanted to stop and see if he was okay, but the marshalls wouldn't have approved. I didn't see him or the car again, though I know he was alright as he was standing behind the armco on the next lap.The way the AE86's engine would just rev and rev with power just building more and more up to the red line was inspiring. I'd change up at 9,000 rpm and this meant on the back straight I'd only just need 4th gear, whereas on the shorter front straight I'd reach the braking area at 9,000 in 3rd before heeling and toeing down and braking hard, accompanied by squirming and smoke off the rear tyres as I entered the top corner. I was pleased the oil cooler, radiator and ducting I've made. It worked well - oil temp briefly hit 120 degrees after 6 hard laps, upon which I'd give it one cool down lap before going hard again. The TRD bushes on the suspension seem to have made a good difference. The car feels tight, although very raw too, also aided by the TRD 2 way differential. Will need to drop the front a bit more to aid front end grip next time and perhaps go for some semi slicks. It's got a slightly noisy pilot bearing in the differential, so that's to be changed on Monday. I've almost finished it now. This weekend I'll probably refit the interior, as it's too noisy for road use without it. Plus it only weighs around 15kg so the saving's very little, really. Got 2 red Bride seats to go into it too, plus a new carbon bonnet from J-Blood and a few more goodies. DCD's going to be picking it up and having it for a few days, to do his magic and give his verdict, so no doubt you'll see this car in J-Tuner as well as his blog shortly. He'll need ear plugs for the 2 hour trip home in it though! I love this car. It's more fun than the RX-7 as it's even more challenging to drive. Never thought I'd say that! Roll on the next track day. Here's some pics of what it's looking like at the moment. I intend to make this Hatch Rokku into my ideal old skool car - It will be used daily, can't resist ![]() ![]() ![]() ![]() ![]() ![]() Miguel |

Hey Wayne, good to hear from you. Hope the project car's coming along well. The rest of the body bits will be with you both soon!! ![]() Thanks for the compliments! It goes better than it looks... If you can stand the noise. Also manages to turn most people's heads as they watch / hear it go past |

Good to hear it. The Newera AE86 is very sweet. But get that remaining sound deadening asphalt shite off the floor man! That car is too good to be only candy stripped! What size/offset are those Wats by the way? |

Cheers for the interest! ![]() I had considered taking out the sound deadening, but (Ask Brooksie - He's been in it!!) this car's so damn loud, I can't hear myself speak at Motorway speeds and have to shout at the passenger, so taking out the sound deadening will only serve to make it worse It's a car to be used daily, so I'm not so sure I want to save 20 kilos in sound deadening, plus around 15 kilos in interior - just to have a barely noticable improvement in performance. If it's too noisy it'll just be friggin' annoying to drive long distances to track days, etc, which sorta defeats the purpose of having built it. By the same token, I could have removed the air conditioning and power steering which would probably have saved around 20kg of weight again, as would changing the windows for plexiglass, but a car in Japan without A/C especially a dark one will be like driving in a Sauna for 3 months of the year...45 degrees inside a car with humid weather doesn't make for a comfortable drive (Which is why all cars in Japan are originally fitted with A/C)!! Haven't yet decided if I'll refit all or only part of the interior, but at least I'm going to refit the carpet and centre console. It weighs bugger all anyways. It's got more power than some of the D1 AE86's (Around 25 bhp) so to me there's plenty to play with. I'm not trying to become a D1 driver, anyways The engine work came to a total of around £6,000, but that included buying a used AE92 for it's engine, the throttle bodies, Freedom ECU and mapping, TRD clutch and a new exhaust manifold - all fitted whilst the car was at Techno Pro Spirits. The other mods have been fitted by ourselves where time allows. The wheels are new 15" RS Watanabes of zero offset. Paz, we can get anything for your car at discount - Drop me an e-mail if I can be of help As for the old parts that were on the car, I've donated them to a friendly teenager who works at my local petrol station who also has an AE86. He doesn't have much to spend on his car, so I figure it's a good cause. As he's only 18 and into drifting, perhaps I'll help him become a future D1 star He's already fitted my old engine, manifold, exhaust, etc. He tried the carbs, but like me, found the manifold's cr@p, basically - making them impossible to set up perfectly.. So he's gone back to standard fuel injection again! Last edited by Miguel-Newera; 25-11-2005 at 14:07. |

have you had to adjust the gear ratios to the new engine power characteristics?

Fair play Mr Mig, put the interior back in then and go round tracks in relative luxury .Too many people strip out interiors just to try and be cool - and most of these fools leave in the heaviest part (ie the bitumen shite), but you know what you want so that's cool. Stripped AE86's are sweet (with earplugs on ITB'd ones!), but I agree, it'd be nice to have some carpet to munch on and to not arrive at your destination deaf... My interior was 2-tone blue so I had no choice but to strip it out you see ![]() Nice story about the local Takumi-type kid too... I'm doing the same kinda thing with the local chavs round here, only not giving free parts away! What width are the Wats by the way? 7.5J? |

The Watanabes are 8.5J's with RE-01R Potenza 195/50/R15 tyres. Not ideal for drifting, as I ought to have 14" rims with 175's on for that... So I have a spare set of 14" RS Watanabe rims the car originally came with, just for dedicated drifting. It still drifts okay on the tyres I have fitted at the moment, anyways - but realistically I'm not going to be drifting it everywhere I go, there's not that many places to do it in Tokyo, except the docks and stuff like that ![]() It has a much shorter final drive, which it came with when I bought it... Don't know what the ratio is...All I know is that with the original speedo at an indicated 40 km/h it was doing around 30 in reality (It failed the Japanese shaken 1st time because the Speedo wasn't accurate). So we figured out it would do 40km/h at 3,500 rpm in 2nd and passed it using that... Sometime, I'll properly calibrate the Apexi Rev Speed Meter as it's not got the original instruments any more, they were butchered to make way for the new gauges. |

175's with 200hp?! Haha, man that'll be... fun? Ive always used 185's and 195's, with stock engines, i reckon just buy some decent-ish 185's and you'll be happy with the way it slides and that. FM901 are good for the rear and cheap over there. With regards to your speedo, try this to find out what ratio Ring and Pinion you have: http://www.f-body.org/gears/ Stick these T50 ratios into the calculator: 1st 3.587:1 2nd 2.022:1 3rd 1.384:1 4th 1.000:1 5th 0.861:1 Then play around with the ring and pinion (axle ratio) to see if you get close to the gear speeds you have. Id guess it'll be a 4.788. The other common options are 4.3, 4.5 and 5.1.. Hope that helps |

Ueo always talks of 14" rims with 185's as the best choice for drifting on an AE86, but then again, his car weighs the absolute minimum for an AE86 and revs to well beyond 10,000 rpm with it's Tomei built race engine, so I dunno. Keichi Tsuchiya's mint road going AE86 with around 220 bhp runs 195/50-R15's. It'll be 185's ideally for drifting with mine, maybe.. The RE-01R's were a bit too grippy, though they're sports tyres, not cheap Chinese brands which the drifters here tend to favour. I'll try that stuff in the calculator. Nice! ![]() The Tsuchiya street AE86 runs a 4.778 final drive with a close ratio in the 1st 3 gears. Close ratio gearsets aren't all that expensive. Fitting's a bit of a pain, but not that bad, I guess... Cheers Paz! |
