7AGE Build

[apardal]

Hi!

NOTE: Not AE86 related as I've installed the 7AGE 16v on my MR2 AW11 which I'm racing more frequently now.

I've built a 7AGE with almost everything stock and I'm now wanting to get more power out of it. It dynoed a weak 125hp@crank but laptimes became a little faster compared to the stock 4AGE so I believe the dyno was a bit conservative, and since then I've adjusted the fuel which made the car run cooler and faster.

It has been running fine except for the fact that the oil heats up a lot more than my previous 4AGE with the same exact cooling system. It doesn't go below 120ºC with an electrical oil pump scavenging oil from the oil pan to the front mounted radiator running full time around the track (when before with the stock 4AGE it was running between 90-100ºC with the external oil pump working a few seconds per lap).

The calculated CR is 10.6:1 and I'm trying to find out what are the biggest camshafts in lift and duration keeping the stock intake manifold and getting a nice ECU with bigger injectors.

Group A engines ran 304 duration low lift (7.5mm) cams with the stock manifold but I believe it is possible to run a more round engine with for example the 288º 8.5mm TODA camshafts.

Do you guys have any experience with built 7AGE's keeping the stock manifold?
