While I've seen a few poor smallport castings.... this one is a pretty good casting, with decent chambers, and pretty good port-bowl alignment. What it doesn't have is a good short radius..... on ALL of the bowls.... Huh

In one of the email correspondences with this client..... "On my Cyrillic Russian keyboard when I typed "Спасибо товарищ" [thank you comrade] the next word suggestion that came up was "Сталин" [Stalin] ? looks like my phone is a cold war veteran & a good party member!"

So this engine will be using a set of ITBs. It will be using a T3 adapter.


The ITB adapter needs a bit of blending.....

[Image: AEU86 AE86 - OST-048: Спасибо товарищ Сталин]


As do the intake ports... they too need some gentle blending

[Image: AEU86 AE86 - OST-048: Спасибо товарищ Сталин]



I pick up the head later today, so more to come....... Hurray!

Assembly.... This client is using a Supertech spring/retainer kit.

[Image: AEU86 AE86 - OST-048: Спасибо товарищ Сталин]


I've not been a fan of the Supertech kit. One reason is because I've not been a fan of the Supertech spring seat....

Kind of a shame actually... as there are many springs out there that can fit the stock spring seat.

[Image: AEU86 AE86 - OST-048: Спасибо товарищ Сталин]



The Supertech spring seat is a flat steel "washer". There is nothing on the Supertech spring seat to help keep the spring located/stable in the spring pocket. Introduce the "Macer" spring seat.

[Image: AEU86 AE86 - OST-048: Спасибо товарищ Сталин]

Richard Macer builds many racing 4AGE heads, and he has found the standard Supertech spring seat to be "wanting", so he designed and had manufactured an improved spring seat

[Image: AEU86 AE86 - OST-048: Спасибо товарищ Сталин]

The Macer seat fits the spring pocket, and the inside "neck" helps keep the spring located, and stable.

If you want to get a set, send me a note, and I'll forward contact info.


Quote:I've not been a fan of the Supertech kit. One reason....



the other reason.... HELP! Supertech Retainer / stock buckets

[Image: AEU86 AE86 - OST-048: Спасибо товарищ Сталин]


I checked valve protrusion through the retainer, I have .025" on the exhaust side, and .030"+ on the intake side... so that concern is no longer a concern.....
