Gostlys 7agte 20v ae85 built on student allowance.

Hi guys, I’m Liam.

Discussion here: http://oldschool.co....dent-allowance/

I found this on trademe, and it was actually being sold by a mate I went to primary school with, had no idea who he was until I saw him, which was cool. I got it for a decent price with a blown head gasket on the 3AU. It had a bit of rust around the door hinges and the rear windows which is why he was selling, also obviously because of the head gasket…

This is how I got it:

After sitting around for two months deciding what I wanted to do with it, I finally decided to get the tired old 3AU and auto box out of it, so paid the mechanic a few dollars to do it in his spare time.

I then got the rust done – the old man promised to bend up some metal and weld it in, but the muppet decided to fiberglass it for the same money, was not impressed at all because a few months later it’s beginning to have rust bubbles forming on it…


Any who, I got the 85 to the mechanics workshop and he ripped out the 3au in a few hours and begun to put in my spare 20v Silvertop 4A with my t50 and competition clutch in it.


At this stage, I pretty much had the entire 20v and 16v conversion for it, however after realizing that I would have to have the firewall cut and have some crappy looking waterlines made up for the FWD engine, I binned the idea of the 20v N/a Silvertop with t50 and ended up flogging it off for a fair few dollars.

When I was out shopping for a new rear end for my ke35 I met a man called Alistair in Hamilton, he knows his stuff about old Toyota’s and how to build them/ rally them. I told him that I was looking at building something different for an ae85/6 and he suggested building a N/A 7age 20v with some decent cams and head work done to it to make it sit in the 200-220HP range which got my interested in that sort of engine, I came across a few cars that have had this conversion done to it and decided that I wanted to turbo one.

I found a complete 20v Silvertop this time which had been rebuilt – with receipts and the larger T28 Garrett turbo ( supposedly capable of 350HP ).

Then after trolling all the 4A websites trying to look for a RWD plenum that would fit the Silvertop’s ITB’s I found a man in Tauranga that would build me one for fairly cheap, $325 if I came to pick it up, which was no real problem as I was off uni and both me and the missus were terribly bored. We headed down to the Mount and spent the day in the sun whilst he finished up the plenum, its not the prettiest looking one as I havn’t decided wether or not to Powder coat it or polish it up but it was less than half price of what MRP could do one for. And most importantly, it fits.

After my trip down to Tauranga, I begun the search for a 7afe block/bottom half. Which isn’t the easiest, they don’t really seem to pop up on trademe too often, and if they do they want big dollars for it, however the Toyota parts/ wreckers on Patiki Road, Avondale, Auckland sold me a block out of a working Caldina for $200 cash – the block had done just over 220k’s but it didn’t really worry me as it was going to be rebuilt anyways.

Being a poor student with other cost, I can’t afford to build the car up to ‘showcar’ spec with all the luxury goods, so instead of forking out the 2grand for a set of Brides, I bought some new fixed back KW’s for it, and because im a tightass, I decided that I didn’t want to fork out another $400 for bolt on seat rails, so instead chopped up the old ae85 interior and used the rails on the KW’s.

Eventually, I got bored with trying to strip out the interior and was running out of money quickly as I was wasting it on other necessities like tattoo’s and booze :P However, I did manage to score a new intercooler for $100, it’s a bit of a big one, but hey. And I got a triple core ae86 brand new radiator + Momo leather wheel + bosskit + ke70 lovell springs for a Honda Civic radiator I had out of my ke35 which will be used for my 85.

A smaller update. Got some new fiberglass guards + some choice old American gauges for the ae85 today, will get them put on the car when I can find someone to chop the rear guards and make them into a widebody for me.

After saving for a little while, I managed to buy SAMQ’s RWD 20V waterkit and his 1NZ coilpack adapter plate. Still pateintly waiting for it too arrive before the motor starts actually getting its rebuild.

The plan is to have a 20v 7AGTE that is still easiest enough to daily to uni, but enough responsiveness to take to Hori Dori days/ the track in the weekends. I’ve managed to source a W55 for it, no A-W bellhousing as of yet due to expenses. And also managed to find a F series LSD for my ae85, not as heavy as a hilux, cheaper to buy and I believe some of the Altezza’s still have F series, so plenty of parts availiable too.

The box I bought cheap off trademe - supposedly had 2nd gear buggered, but no real problem as I was wanting one or two boxes for spare parts anyways.

Today, I went out to South Auckland to pick up the forged conrods for the 7A, I got them and saved a few dollars by paying cash for them. which I was happy with :P and getting him ( Barry from MRP ) to mod my crank sprocket so standard 16v/ silvertop timing belt and oil filters can bolt on without modding/ trying to source the Porsche timing belts and shaving off one of the teeth to make it fit.

I also found out, after asking around on here, there was no real point about trying to change the 6 bolt 7afe crank to suit a 8 bolt 4a flywheel/ clutch, and that a 4afe/5afe flywheel fit them so am on the lookout one on of those too. Block is being stripped tomorrow and being cleaned up ready to be acid dipped/ powdercoated/ looking all nice and pretty.

* Will continue to add pics/ details/ actual info about it over next few days.

Found these quite interesting, First pic: Forged 7A conrods, second pic: Standard 7A conrod. And third picture: 7AFE crank on left, and bluetop 4AGE 16v Crank on right.

From what I can see, aside from the 7afe crank being 6 bolt, and the 4age being 8. There seems to be no real difference?

Would it be worth the trouble now that the crank is actually out, to turn it into a 'knife crank'?

* Small update..

Mechanic stripped off my 20v Silvertop for me, entire head sitting in pieces on his bench.

wp000806.jpg

Problem was, in the process of pulling it out, it looked like the muppet that sold it too me as a 'working' engine had somehow managed to seize the head, the cam with the VVTI had massive grooves and chunks missing out of it -.- and it looked like he had somehow heated it up as theres also burn marks all over the cams lol.

Doesn't matter... I had a spare 20v Silvertop head, which was in A LOT better condition...

He had a quick look at the block, and said the pistons for some odd reason looked good and there wasn't any marking on the block.. So probs just gonna flog it off on trademe for $1 reserve...

wp000807e.jpg

Next up on the list is somehow making the Turbo manifold fit... Its obviously off a 16v head, and doesn't quite match up on the end two bolts on the 20v head, so come Monday/ Tuesday the 'newer' non buggered head will be tested/ skimmed and going to see if the Engine reconditioner can somehow add on something to make the manifold bolt onto all 5 holes properly.

  • 3 weeks later...

* Update

7afe bottom gasket set arrived, 20v silvertop head gasket set arrived and SamQ's RWD waterlines/ coilpack adapter plate have arrived in the country! Massively happy due to the first set going missing over a month ago! Will throw up some pictures when the block is starting to get put together.

All new bearings/ piston rings/ frost plugs have been sitting awaiting!

This turned up today:

Uploaded with ImageShack.us

SamQ's second kit he sent out arrived, just paid the customs bill... $120... Stupid how you end up paying tax on it multiple times... Atleast that'll be here by the end of the week.

^ This is what the engineer made up for me to make the 16v turbo manifold fit perfectly on the 20v head.. there is two of them and they will clamp down and hold it in place

headbolts.jpg

Annnnnd. As I asked about earlier, my 7afe crank is at the engineers now becoming an 8 bolt to fit the GZE flywheel/ clutch :P

Probably last update for a lil... My mechanic's daughter is having a baby girl soon and he won't be working for the next couple weeks...

Buuuuuuuuuump. Got bored, so installed that 6 point brace in the back... Looks flash and clean haha.. ran out of money's 'cause I'm supposedly not a full time student - but did manage to buy brand new Exedy clutch with heavy duty pressure plate... Also from Prowhole sale dude - cheap too like $350? And just bought these :P 15x8's - nothing spectacular but I've always wanted something similar to smoothies...

And... My crank is now like this: bottomend8.jpg

Got that all done quite cheaply - like $140, but he also cleaned up my flywheel. He showed me this really complex picture about how he did it, and looks preeeetty mint.

Its now gone to the Head reconditioner to get a grind :/ Unfortunately need to get new bearings and shit 'cause the ones I bought ain't gonna fit now.. Hopefully Appco will swap em :( my 20v ST head is also down there getting crack tested/ skimmed/ valve seats cut and all that Jazz...

Lastly, block is FINALLY on the engine stand being cleaned up, and painted whilst we await the return of my crank/ oversized bearings.

Chuuuuuuuuuur.
