a mate of mine (i think dales on here) is doing it, using a 7afe and a s/c mr2 to make a 1.8l s/c. should be interesting. there was a 20v 7age turbo in australia, www.turbofast.com.au, and some ppl have done it on www.club4ag.com

cheers

ive thought about making a s/c 7age before, but have been told that the conrods are too weak so the cost of new ones put me off.

Have a search on the net for it, its been done a fair few times. I was looking at it a few weeks ago ask I want to make a 7AGTE (7A block, crank etc, 4AGE head and a turbo). Found a few good reads. You'll need a longer cambelt, one off a porsche 944 (or 924) is a perfect fit apparently. But if you're actually set on doing this then you'll find these things out with a little searching :) Best of luck, and if you do do it then chuck up some info about how it went and issues you came across

i saw omething on a site of someone who is very experienced in these sorts of adaptations and he said that the costs out weigh the bennifits
and the result is a higher powered weak engine

no offence to people who have/are doing it this is just what i read
ill try find the link for it

This conversion has been done in many different ways but all you end up with is a weak engine. If you want more power turbo a GZE engine. If you want to go class racing then spend some money on a 16V 4A-GE.

Just my 2c. :D

Idea is there for more power and torque but at more money. Yes conrods are weak. Also 7afe flywheel is not as strong, 6 bolts instead of 8, or something along those lines. So less strength in conrods = less max rpm. You can still rev it to the 4age limit with new rods. But in bang for buck wise, better to put the money into better mods for a 4age, like a gze, or turbo. Club 4ag has some good info(you no americans bigger is better) , and the aussie one looks mad. Lots of folding stuff though.

With limited cash stick to a 4age. If your going all out, the 7age might be for you, but only if its done with no expense spared.

As Nick said, I'm giving it a go. My aw11 SC bits all bolted onto a 7afe block. (pistons swapped of course). Yes the rods are weaker but are normally only a problem if you want to rev high. I have been talking to a guy in the states who did the same thing but with a twin charge set-up. Has had no problems with standard rods and is making good power. I just want to try it to be different. Unfortunatly I have not got time to spend on it at the mo (working 7 days) but should be back onto it at Xmas time.
You're just jealous the voices are talking to me!
