so i talked to my machanic before he said he could do the conversion etc, now he says he can't :( i have a 4age silvertop 20v bigport and a ke70 ... he says it can't be done because you will need to cut the firewall and the radiator hoses will run along over the extractors etc... can anyone reccomend some1 to do it thats if it can even be done ..

greetings,

 

its not easy, but with the right bits becomes bolt up.

here is another good thread:

 

http://www.rollaclub.com/board/topic/52240-4age-20v-into-ke70-confustion-parts-list/

 

you do realise, that to pay someone to do this, you are looking at something like $10k+ ?

 

kaizen garage in brisbane are known to work alot with toyotas and RWD. good luck!

Hell give me 10k Ill do it for you. Ill even tune it.

I'm doing a blacktop 20v in my 70.

Your mechanic isn't a problem solver is he....

You need to move your distributor and/or remove it and get an aftermarket ECU and convert to coil on plug. You'll probably need an aftermarket ECU anyway because you have an AFM'd silvertop

Then you need one of these Cooling Systems and then your usual RWD stuff, spigot bearing, mounts, crossmembers, tailshaft etc

The search bar will solve your problems ;)

 

By the way...How do those bigports go? haha

is the main issue the cooling ? (like thats gna cost me the most) am i better off swapping my ke70 for a ae71 or something ? or swapping my 20v for a 16v ? iv got oversized cams, high comp pistons the lot,

Yes there is no such thing as a silvertop Bigport.

 

The 4age generations are like this:

(basic terms anyhow)

 

1- Bigport (ae86 aw11 and ae82).

2- 7 rib bigport (not many made - crosses over in late ae82 and early ae92).

3- Smallport (ae9x series corolla).

4- Silvertop 20v (ae101 levin and trueno).

5- Blacktop 20v. (ae11 series levin and trueno).

 

Along the way there were supercharged versions called 4agze. These were in AW11 MR2s(bigport) and ae92 levin (smallport).

 

For all the finer points, google for Bill Sherwoods 4age page and read it all. Its extremely enlightening.

@littleredspirit, yours is a ae71..mines a ke70 .. did you do the conversion yourself or pay someone ?

4. silvertop 20v (ae101 levin)

YOUR main issue will be your AFM and the need for an aftermarket ECU.

Take LittleRed up on his offer. Give him a call.

You don't to swap anything with anything, you just need to spend a little bit more money.

i do have an aftermarket ecu... which i was running in my ae92 with my motor (just crashed it so decided to do this pain in the ass conversion lol )

Your better off making a decision and sticking with it until the bitter end.

 

If already have the parts to build a hot 20v, do that. Its going to make almost twice the power of a stock bigport.

 

I just hope you budgeted for a programmable ecu. You can use an adaptronic basic select, wolf 3d, haltech, it doesnt really matter as long as its not a microtech.

Listen to LittleRed ^^^^
