The ambitious goal - Early bigport 4agze into AE95 sr5

[PrettyCoolWagon]

Taking my granny spec AE95 to suspension place this Friday to discuss raised suspension options, larger wheels, pros cons & budget

[TERRA Operative]

Be careful with bigger wheels, you can only increase or decrease rim size by 2" either way, tyre diameter by 15mm larger or smaller and rim width by 26mm larger than the largest optional wheel size.
You have to be careful with offset too, as widening the wheel track beyond

[PrettyCoolWagon]

Yeah, I looked up the reg's & last I remember in Vic. we're only allowed to increase overal wheel size by 25mm but I think that's because of speedo adjustment.
I'm wondering if this can be worked around because there are digital adjusters that can be fitted for 4agze engines & I've seen a number of small 4wd's like suziki's driving around with serious suspension raises & way larger wheels than standard.

From what I know about width, so long as no part of the wheel protrudes out past the body of the car you're ok. ... & rubber strips can also fitted to the guards to extend the coverage above & around a wheel that does protrude a little past the body. As seen on many old hilux 4 runners & surfs.

Their main business is suspension for street, drag, race & drift modified vehicles, so they do a lot of engineering compliance. Should come away with a better understanding of steering in general what's reasonably possible for my wagon

[TERRA Operative]

Yea, as long as you use a good shop, you should be fine. Then there's always engineering certificates for the more wild mods....

[PrettyCoolWagon]

Well I might consider cutting some of the engine bay wall open a bit more, just down the bottom where the steering gear goes through to the wheel.

That's the main problem, the more I drop the wheels down & increase the steering angle, the closer it gets to rubbing against the engine bay wall.

I can't see a bit of cutting & re-inforcing being too much of a problem.

[PrettyCoolWagon]

Well, it was an interesting session, few old 60's formula cars around & big GT falcon + other boy racer cars..

Suspension raise is more complex than I figured but I definitely learned more.

We're talking 4 grand to get the basics right.. plus more on top for fine tuning test drives/mod's..

Things like angling the front of the whole rear axle up to meet the drive shaft, which would require multiple fabricated extensions...

I didn't want to spend that much but I can see what's involved & where the money goes... especially when you consider the cost of good shocks & dampers etc..

Given me a lot to think about..

Will probably approach a couple more suspension shops before making a final decision based on budget & end result..

Update:

Changed plans guys.

Building a 7AGZE instead.
As soon as I made this decision, it felt right. A 1.8L SC14 supercharged engine will be much better suited to powering the heavy AWD drive train of my wagon.
Kerb Weight (kg): 1210kg
Gross Vehicle Weight (kg): 1680kg

Everyone knows the weakest point of this engine build is the factory 7afe con-rods so I've bought some forged one's from 'spool'
They featured in a mag like fast fours or something. Very competative prices.

Also bought a 7afe engine last weekend. Thanks 'Sam_Q'

As a newb engine builder/modder I'm also finding this you tube series very helpful so thought it was worth sharing.

For a small fee Bazda in NZ has offered to re-machine crank pulley key slot to re-align factory timing.

i'm not really familiar with the 7 engine.

will this easily couple up to the ae95 box? and will you need custom engine mounts?

i'm about to pull my 20v out of my wagon, and i'm exploring different options.

[PrettyCoolWagon]

Hi Marty,

Is your wagon an AE95 too?

7A's & 4A's have the same engine mounts.
When you look in the engine bay you can't really tell the difference at first glance. It's just that the block of a 7A is 15.4mm higher than 4A blocks, hence the increase to 1.8L

I've heard the 20valves go well on the 1.8 block but have no experience myself. Add a turbo & you have some serious power. Best 7agte 20valve I know of is Bazda's from NZ

Here's all his specs:

GOOGLE Search 7age, 7agte FOR MORE INFO

By the way, if anyone has a HKS Graphics Control Computer that compliments the HKS PFC F-con 4AGZE piggy back system please PM me.

Thanks

yeah i gots an ae95, with a 20v silver top.

recently my box began slipping out of 5th gear, really annoying.

so since i have to pull out the whole engine and box to repair it, i've decided i'll upgrade the engine too.

[PrettyCoolWagon]

Sounds like a good idea - keep us posted.
Glad to meet another AE95 owner.

I find most people who bag this car have never driven one & often confuse it with the tercel. (completely different cars)

Admittedly the 4afe was a poor choice by toyota for a heavy wagon, given that they put 100kw 4age's in seca's of a similar era

Stronger engine & stiffer suspension in this wagon & you have a toyota tough ride.

yeah the current plan is to put the GZE in, that should give me a fair bit more torque. the hard part will be trying to find a way to mount an intercooler without any changes to the appearance of the vehicle. maybe a small front mount painted black can be tucked in there somewhere.

i already have the king springs/kyb combo for suspension, and it's brilliant. that car has seen a lot of high speed gravel road driving.

will the 7a block bolt up to the ae95 bell housing? what's a 7a block worth nowdays?

[PrettyCoolWagon]

Hi Marty,

Front mount intercooler sounds like the way to go. When you consider the size of the original GZE intercooler it shouldn't be a problem.

To be fair though I'm no expert. In fact I'm a complete newb who just does a lot of reading, cross referencing asking questions of people who've done it a million times.

Regarding your question about the bellhousing.
Someone else might be able to give a better answer than me but as far as I know there's very little difference between a 4a block & 7a block except the extra height at the top near the deck.

As fas as I'm aware the bolting of E-series gearbox / bell housing on any 4A** motor is a straight forward affair.
However it's clutches, flywheels sizes and gearbox splines that may vary in size.
So a bit more research to be done there...

I'm considering a celica LSD front diff, but still using the AE95's gears and upgrading clutc fork and synchro's as I've also had worn synchromeshes like you mentioned.
The materials clutch forks were made of were improved inlater E-series gearboxes and IIRC an additional oil feed was placed around 3rd gear to help reduce wear and tear and improve longevity.

Here's a few threads I dug up re: AE95's and engine conversions.
Hope it helps.

Dude, yours is a twincam too (the F in 4AFE refers to narrow angle {or economy spec} twincam head). I can't say whether it identical to other 4AFEs (including AE101's) but I am pretty sure any 4AFE will bolt straight in with no modifications. Also a 7AFE should bolt in and offer a little more performance, although you would probably want to use a 7AFE ECU and injectors. I reckon a 7AFE with a low boost turbo would be an absolute hoot in one of these, and probably cheaper and definitely easier than a 20V conversion.


http://au.toyotaownersclub.com/forum...h-sick-engine/
imo a 7afe convo would be better overall daily driving for the said budget.
The AE93R corolla RV 7AFE motor would be the best bet, motor should fit in (might need to grind abit off the block to fit the transfercase), engine loom should connect up (havent tried but they are from the same era/series, so should?

(good AE95 thread with photos)
http://forums.club4ag.com/zerothread?id=87810
He States: The 7afe block is wayyyy to wide to fit the All Trac Transmission.
But I've since been in contact with him on the alltracwagon.net website and he said he didn't actually measure the block, he was just going by photos he's seen.



Also:
Quote from PM sent to 'Bazda' who's already done this conversion into a levin, which makes no difference because both cars are E90 chassis. Body's a bit different but engine bay is identical.

"7afe block has the same bolt pattern as the 4a block.

7afe block is around 15mm taller than the 4a block thats all.

It will bolt up perfectly. "

The guy who said the 7afe block is way too wide was talking about the notched area in the 4afe similar to 20v's that requires some grinding..
I showed him a photo of the 7a block I'm using which also has the notch.
But people have put 4AGZE's into AE95's and 4AGZE's use a straight block without the notch that some other 4A** blocks have, so I'm 100% sure it'll go in perfectly so long as the extra grinding's done to clear the transfer case.

[PrettyCoolWagon]

Small amounts of evidence that 7AGE has already been done in an AE95
