Ok there it is i have seen it up for a few weeks now but im not really sure if its worth it.

I am ready to pull out my engine and start the 7agte conversion and i thought this would be a good start.

What do you guys think about it?

Yes this would be a good start because it`s the large port version , but think about a rebuild of the head for reliability and performance.

Even with the head you`ll need to find out a corrolla gts fwd for others parts also.

You'd have to source a somplete intake manifold and throttle body with attached sensors (TVIS plate optional), fuel rail, injectors, distributor, coil/ignitor, AFM, and at least a partial engine harness with CTS plug, O2 plug, temp plugs, AFM plug, TPS plug, and ECU plugs. The harness part can be eliminated if you choose to go with a standalone ECU. For the engine harness, I highly recomend you source one from a 92 Geo Prizm GSI if at all possible. That way, you can go with a complete MAP set-up instead of the AFM. Some models of the Corolla GTS AFMs don't read-out the proper voltage for a piggyback set-up so tuning will be nearly impossible with the stock ECU, so I'd either reccomend a MAP sensored JDM set-up (or the VERY VERY rare USDM 92 Geo Prizm GSI wiring set-up) for the best tuning capabilities.

Whats the power increase or reason for swaping the 4age head? I know its a performance designed head compared to a economey. But I dont really see why it would be worth swaping all that, and why not just swap the whole, engine for e comparable bottom end.

The reason would be to maintain the 7A displacement and gain the 4AG flow and aftermarket support. A stock 4AG head can probably out-performan a street-port 7AF head anyday...

Yeah I also forgot that the 4age was a 1.6 .... i wounder how much power it would run n/a

Aye, i completely understand thats it's not all ill need was just wondering if it would be a good start and you more then answered my questions.

As for the ECU i have a motec dealer a few miles from house, So I will more then likely bring it up to them when i am done and see what the Motec M4 Standalone will run.

A: you are going to spend a grand or so on a standalone EMS... on an engine that won't buck over 130 whp... meaning you are Hella dedicated to the 7afe.

Or....

B:you don't realize that your money can be better spent on a swap of some sort than on a econo-block boat anchor.
