ATTENTION silver top and black top owners

hi guys how are u hope u all are well

i have recently been offered a 4age silver top engine in very good condition complete with gear.ac compressor,power steering,wiring on a very reasonable price lets say its costing half of the 4afe i was going for........

i have some questions for this engine

first
is it reliable
is reduction of some oil in this engine normal
does it make little sound of tappets when idle
and will fitting black top wiring on it cause problems
and how to recodnize that the engine is fine
if compression test is done what should be the result which makes it a good engine
and are their any cons in it

your share of experiences would be very much appreciated thank u

Loss of oil - yes but not much at all.. If you use a low grade oil it will use more.. I run 10w40 Fully synthetic Rock Oil (made for motorcycles) and now compared to using car oil mine doesnt use anything at all

Tappet sound is fine, you just need to get the head re-shimmed if it annoys you that much... otherwise its fine

Yes it will run on blacktop wiring loom and ecu

Compression test it - you should get results between 185-195.. Allow up to 15psi difference between cylinders but really you wouldnt want more than 5 or 10

Cons of a silvertop... fuel efficiency? lol nah only thing is you cant run open stacks unless you convert to map from the blacktop.. but seeing as your getting blacktop loom you may be ok

I'm guessing you've heard the engine running??
Just what Richard said although to running the BT loom you will need the MAP sensor as you'll lose the AFM (which is a good thing imo). That of course means open trumpets but if you do that you'll have to retune the ECU as it's designed to use the air boxs.

thank u richard bro and yes im getting black top loom what is the difference in afm and map
and ill mopstly run it on gas because our petrol makes it knock alot and is it harmful the knocking

i havent heard the engine running just seen videos of that
how map is better than afm plzz elabourate as i am new to silver top
and how hard will the wiring be inside the dash
and what are the trumpets and how would i retune the ecu

you cant retune the ecu, you need to get standalone if you would like to mess around with it.. look into tomie poncams as they are a drop in upgrade and work with everything standard..

here is a 3sge with stacks:

should i go for it.its either this
or a 4afe or 7afe


and could tapit noise be reduced to make it like a silent engine
and is this engine reliable and what is done in shimming
over here shim means to add a thin copper to the gasket where the piston holes are

The silver/black top is way more powerful.

there are metal "shims" on each valve, which are different sizes and they wear so create a tapping noise (BT/ST do not actually have tappits )

so how are these shims made or created and or repaired i need alot of info on this engine if i want to make the swap

you have to buy a set of shims and a mechanic would have to fit them

could u explain shims plz if its not a problem


and thank u for all the info given till now richard bro

from wiki:

A valve shim is a disc of hardened metal of precisely calibrated height used to adjust the clearance (US:lash) between the back side of the cam-lobe and the valve on which it operates where the cam-lobe operates directly on the valve without an intermediate rocker arm. The shim sits atop a shim bucket which itself sits atop the valve-stem and moves up and down within a machined bore. While hydraulically self adjusting valves are sometimes used for their lack of required adjustment they do not work well in engines capable of high RPMs. In situations like these shims are most often used. As an example most motorcycle engines capable of 8000RPM+ use shim adjustable valves.

20v 4age has solid shims


Shims


Buckets:

this the same type of tappet setup in diesals right.its called auto tappet here

you might be buying a set of very expensive itb's with a free car attatched

hahaha i dont know maybe

so the st with black top wiring is it good compared to

4afe and 7afe in overall

and ps the 7afe and 4afe are worth more here because of high demand

4AGE is 10000000000000000x better lol

Yep, a ST with blacktop ecu and loom is good

how does a ST COST OVER THERE WITH 5 SPEED GEAR AC COMPRESSOR POWER STERRING PUMP ECU AND BT WIRING

engine, loom ecu, probably arouin £500

im getting for 450

will have to check the engine personally though

in december hopefully i will going to check that and have the compression tests i that is a fine engine its mine if not i might as well bring home a 4afe

i wonder how expensive it would be to ship an engine?

50 to 60 bucks if its not to heavy i might remove the front seat and put it there its done most of the time

and thank for shedding that much light bro really appreciate it
