this is from an old topic that inspired my 20v 7age are the rpm figures in this post wrong or did u have a 7afe running at 7200.
if they were running at 7200 then the 20v would shurly be able to extract mor power than the the 16v
One word.....WRONG!!! Have a couple of these conversions under way and a 7AFE race engine in bits right now. The FIA Homologation papers, and from actually building all these engine, the race engine is the first and getting all the attention now, the crank is in fact FORGED!! Also confirmed by Neal Bates Motorsport, which built Simon Evans Group A RV. The weakness link is in fact the rods, which is what happened to mine(going forged now), Caused by a 10,000 RPM missing of Gear change. Shot peening is always a good Idea, and were also done to this engine, and would be fine for street use. I standard form, @ 7000-7200rpm are the limit compared to a late model 16V 4AGE's 8,000 RPM in modded form. As for proof have been Thrashing this particular engine for the Past two years, to a 7800-7900 rpm redline constantly on both the track and on rallies, and it hadn't missed a beat, til this minor slip up. A few Guys did see the car in action at a wakefield practice day a few months back, and from the feedback I got, many didn't believe is was a 7AFE,until I lifted the bonnet.
Now, the flywheel bolts, the 7A has less of them, but they are the same size and diameter as a 4AGE, So at the RPM I run, they could to shear off the bolts, which has happened when my co-driver decide to go from redline in 3rd gear to 2nd and let the 'box do the braking, So something had to give, and I was happy it was the bolts and not the hard to get/find 6-spd I just put in. All this can simply be over come by having the flywheel dowelled, Which I have done, so there is a 'provision'.
I really think that Toysport hadn't done their homework when the wrote that articile.
Now back on to the 7AFE->7AGE topic, the first, I'm hoping, will be at the next Dyno Day. I should be along with the rally car with it's new engine. It is going to be is a balanced 7A bottom, 4AGE pistons, Mildly ported 16V head and and old microtech D5. It's a low budget test engine, which a good friend is going to run and give feed back on. The 2nd is a 7AFE-> 7A 20V which I trying to decide to what degree I want to take it too and what I'm going to fit it too, ie if I put it in the g/friends car, it will be pretty much the same as the 16V, if I find a car, I will be an all out monster, and possible a 2.0L not a 1.8, yet to decide.
