Dear 4A lovers,

I was thinking on converting my 20V Silvertop to turbo. There are some stuff that i know but. Is it worth to rebuilt the engine from the 4AGZE's or to take a complete turbo kit? I heard from some peeps who owns a kononye 7AGTE hybrid engine kacukan 4AGE 20v + 4AGZE bottoms. Which would be less hastle?

Turbo Kit comes with:

I dont need the conrods as silvertop are using 4agze conrods compared to the newer version of its successor blacktop

While making a hybrid version, what i would need is:

4AGZE pistons i think its the small port version 8.9
AR50 turbo
4AGZE blocks
A mod on the 4age gasket
3sgte injectors
new fuel pumps
intercoolers
new headers

Is it worth it? is there anything i missed? has anyone done this?

Price difference between RM1.5k till RM2k. the turbo kit dosent come with the turbines intercoolers wastegates. just the bearings, gaskets, pistons, seals, rods which i dont need, other than that, i have to purchase it on my own. the turbokit is cheeper but lacks in parts while the hybrid match, im still concern on the valve / piston clearance. As for boosting. Im not keen on high boost. Something that can be used as daily and sometimes aggresive driving.

oh ya. the hybrid is definitly hafcut stuff.

that was what i was thinking but being apart of its been used. ok. the AFM on the S/T has to be removed. Still means that i have to fork out cash to get a piggyback rite?

20v 4age and a 16v 4agze size are different in terms of the top part. pistons should fit even tho the gze's are only 16v. sizes of the valves im not quite sure YET. AFAIK, the 4agze and the S/T 20v share the same conrod. Regarding the AFM, thats my common fear. I ever did tried to remove the AFM when i got the engine and i had no idea about it. I thought its just some accessory thing. But i was stopped by a friend who was using the same engine and told me that the AFM must not be removed UNLESS i get the B/T wiring, ECU, and ITB's or getting the piggyback. But i did not research more about the AFM. The only thing that i know that its a MUST HAVE. seems like u know ur way thru on 4a-ge engines.

3K rpm max rev to be exact. I did try it. LOL. for my dumbness. So by using the piggyback, am i able to remove the AFM? or it should still be there? Or should i consider on converting the ITB's wirings and ecu to B/T?
