The silvertop shares the same 48mm diameter thermostat as the 16V models while the Blacktop uses a significantly larger 56mm. - Blade / butterfly diameters: While both engines have round throttle blades, however the Blacktop throttle blades are larger at 45mm compared to the 43mm of the Silvertop. Blacktop 20v also had upgraded lighter flywheel, gears and other internals leading to rev quicker.
All South African Rsis and RXis only came with blacktops Any car with a silvertop has had the motor replaced because the silvertop is cheaper from importers.
The throttle sizes black is 45mm silver is 43mm their oil pumps are different aswell - I know the Hydraulic tentioners are different and the codes aswell , the Black top has a much mkre airflow therefore stands out more .
Blacktop vs silvertop Blacktop Larger ITBs 45mm Larger degree cams Different shaped intake ports on head Difference in combustion chambers Lighter rods with oil relief Hydraulic cam tensioner Higher compression 11:1 / Silvertop is 10.5:1 Different valve pockets/dome on pistons Lighter flywheel Better Branch manifold
Thanks. I bought an f30 last year and was just curious as I’m impressed with its power. Keep up the great content, I’m watching from Perth, Western Australia.

Absolutely loved this episode, many Toyo's in the fam and I must say 20v's one of the best! 👌🏽
We agree!

Blacktop vs silvertop
Blacktop
Larger ITBs 45mm
Larger degree cams
Different shaped intake ports on head
Difference in combustion chambers
Lighter rods with oil relief
Hydraulic cam tensioner
Higher compression 11:1 / Silvertop is 10.5:1
Different valve pockets/dome on pistons
Lighter flywheel
Better Branch manifold
If im not mistaken rsi silvertop has 45mm trottles where as the rxi blacktop has 43mm thats the only difference
The Blacktop has 45mm itbs, lighter Flywheel, cams has higher lift and Silvertop has 43mm
We learn something new everyday. Thanks!
RSi and RXi both came with blacktops in ZA. Any silvertop is imported. RSi was about 1s faster than RXi, due to less weight.

Guys im looking for a decent run x trd that is in a very good condition please lt me know
😊😊😊beautiful car an a big fan
We're could I join a 20v club in durban 😊😊
Would have to do some research bro
Blacktops are bit weaker than Silvertops. Due to BT rods or lighter and thinner than ST. ST bottom with BT works.

What f30 do you own? Interested to understand which variant of the f30 is slower than your rxi.
Video coming soon 👀

💙🤍🔥 This 20V 4AGE is super clean and I think its worth more than 180K
They're holding their price!
@@LoudAddictsYT Yea they holding their value ,I like the fact that everything it's still OEM and untouched throttles, still has the plenum
