OST-070: 7AGE for an N2 Levin
[Image: AEU86 AE86 - OST-070: 7AGE for an N2 Levin]


Back in February I was contacted to build an engine for an N2 Levin replica being built in America. The client was not looking for all out power, but they did want a big valve 7AGE.

more to come....... Big Grin

So then the owner will retain the stock internals of the 7AGE? Or will you replace it with something else instead? Dumb question

Actually this will be a fair bit higher end then that. OST-070 will be running Saenz Rods, OST designed pistons, Ferrea valves, Cat cams 9mm lift cams, and Tec-Arts ITB system. It will remain a wet sump, and the cams duration should peak @ about 8000-8100




from another forum Wrote:I suspect a lot of work going into the head for this one. Big cams and valves. Replacement of the valve seats to accommodate the new valves?

This head will be similar to OST-043, so yes... a great deal of work - beginning with new valve seats.


more to come.... Hurray!

Nice! Thumbs up!
And what about the crank shaft? Will that be MRP or 2ZZ?

Looking forward to this build, please post as many details as possible, also about the block assembly, would be nice to have a good build tread about a 7AGE, as I am going to build one for my car Dodgy

Will you be using a 4AGE Oil pump?

And for the first time, I'll be using Flo's engine bolt kit (Ireland)

[Image: AEU86 AE86 - OST-070: 7AGE for an N2 Levin]


I'll also be using Cat Cams 262/230 9.0mm lift cams, Toda valve springs, and viton rubber valve seals.


more to come.... Hurray!

What is the advantage of the MRP's wet sump, compared to a normal AE86 sump?
