For AE86 and AE71 autos that arrived normal with a 4AC or possibly a 4age 16V the first mounts, gearbox and crossmember will even go well with all of other A-series Toyota engines like the 4age 20V. For that KE70 it's on the other hand more difficult because it ought to have the clutch converted to some hydraulic device, new engine mounting and another gearbox installed. To convert on the hydraulic clutch system another pedal box, clutch learn cylinder, metallic clutch line, flex line and slave cylinder should be fitted.
All our Particular person Throttle bodies are actionned by cable and you could be required to change your pedal and mechanism if working with EThrottle. Modification with your accelerator cable might be essential in selected situation.
Most 20V conversions are for your rear wheel drive type so the initial distributer cap needs to be eliminated as reviewed during the 20v RWD Manual, Which means that several coils are wanted with the ignition method. So from your ECU aspect two ignition outputs inside a squander spark set up or four for impartial coils.
– The Blacktop has a bigger volume airbox. The opposite important variance may be the Silvertop airbox has a horizontal split amongst the lid and The bottom, as a result the bolts are wound from the prime down.
Im looking at dropping the 4A-C and desired to determine what your experiance was with each of the 4AGE engines:
From my practical experience Along with the 20v and i've owned a Numerous of these (generally fwd tho). The blacktop is a Substantially nicer / cost-free reving engine. To me the main difference within the 20v's is comparable from finding in a very bigport vs smallport amongst The 2.
The very best mounted intercooler will in good shape underneath the Generally aspirated MR2 hood and will require a hood scoop on FWD Corollas (but a front mount intercooler is still the most effective set-up. The larger (fourteen psi) crank pulley is a must.
To allow for that Blacktop’s want for just a vacuum signal (see “Load metering”) a larger portion of metal was extra on lower Section of the flange face of The pinnacle to mate from the inlet manifold. Be sure to see underneath “Inlet manifolds” To find out more.
Regardless that the Blacktop head incorporates a extra open up combustion chamber (see “Head combustion- chambers”) it nevertheless has a higher static compression ratio (see “compression ratio”), this is solely due to the piston design. The Silvertop piston contains a pretty tiny dome with two deeply angled exhaust flycuts, two average internal flycuts along with a reasonable flat middle flycut for the center ingestion valve. The Blacktop piston is very distinct, to accommodate to the more substantial chamber the dome is noticeably higher with reduced flycuts. The exhaust flycuts are still present but a lot more website shallow and only the middle consumption flycuts stays but even that's merely a little flat circular dish machined out.
Re: ITB Conversion on sixteen valve 4AGE probly should have outlined what my set up was in the beginning! sorry.
nicely buddy could you explain to me what 12 months supra gasoline pump to use and does the 4agze injectors make any dfference without having turbo charging
They don't seem to be interchangeable with out modifications on the wiring loom / harness. See out Workshop guide posting for a guidebook on converting this Silvertop wiring loom / harness to get suitable which has a Blacktop ECU.
If only a common operate all around blast for exciting dont care about lowish killawasp or maybe the odd engine rebuild then go smallport.
*whole collection 1 AE82 ADM Bigport Map ecu/harness/injectors/dizzy/map sensor (This is actually the just one Using the yellow 2 pin plug you bridge to have codes, not the Analysis block with te/te1 & E1) from the mates 86' twincam seca - this one had the pink injectors.
