- THE RESULTS ARE IN! What can the 8HP70 handle? And is this the best transmission swap for a Nissan Silvia S14 making 800HP? We've done some testing and it's time to talk about it!
In this episode, we catch back up with Mitch’s Nissan Silvia S14 build which received an 8HP swap, a fully tunable gearbox a little over 2 months ago! The 8HP is one of the most popular transmissions going at the moment and we've been eager to see how this transmission performs street driving, transbrake testing and track time!
The 8HP 8-Speed Automatic Transmission is a BMW transmission upgrade made possible through an 8HP engine adapter to suit RB26/30 and full kit provided by Track Industries. This variant specifically, the 8HP70 transmission, allows you to choose between automatic and manual operation with a sequential shifter! Yes, that means 8 speed automatic on the way to dinner and sequential flat shift on the way home!

These videos are so exciting. I have a 86 Monte Carlo with a 5.3, Terminator X and 2004r I was going to procharge but now I plan on swapping a 8hp70 with a Turbo Lamek into it first. Looking at all these swaps it really doesn't seem like a real chore to get these things up in running. The goal is to find the 8hp's now before they skyrocket in price from all the swaps. I might actually buy 2 just in case 😅.
Building an E36 M52B28 Turbo with an 8HP right now can't wait to see the power delivery and drivability with the 8HP.
What an absolutely awesome build.
At the end of the video there those shifts were so delayed holy shit hahaha
Pwoooarrr 👌
Do you have a video on the wilwood brakes installed on this car?
Sam for president 🫡
awesome what you did with AC
How does the lock-up clutch in the torque converter get utilized and when does it turn on?
very nice
How much roughly to do a gearbox swap like this?
Where did you take the cover photo?
Awesome build, what diff ratio is in the car?
4.1 at present the owner is going to a 3.54 gtr diff 👌🏼
@StreetRaceSolutions is the 4.1 too short for the 8hp?
@@phillipstephen5520 likely would limit the top speed of the car to around 130-135 if I had to guess. If the 8HPs output shaft goes past like 7200rpm you risk blowing it up from my reading.
Correct me if I’m wrong but with the 8HP the way the box shifts or performs is all controlled buy line pressure. Correct ?
Interesting concept for an s14. If they are going to all that trouble why not fit paddles behind the wheel as well?
You can if that’s what you want
Think it comes down to personal preference. That's the great thing about personal choice
@@yusufozzy You suppose water is wet and the sky is blue?
Wait... my car came with this transmission... can I add the clutch feature? That would be awesome.
Yes, just needs a sensor on the clutch paddle
Down shifts looked real lazy. Can that be adjusted to be more instant
you have absolute full control over all the parameters to fine tune as desired/needed. auto blipping is also supported
How much work was involved getting the box to fit the tunnel?
Not much at all. We have lowered the engine in the car so I think that helps.
@@StreetRaceSolutions we are doing one now so was curious to know if any 'massaging' would be required. I know the die grinder will get a work out on the box, but lets hope the car doesnt need too much
@@bradsmith588 msg track industries man they’re the go to for 8hp boxes
Would this fit an jzs161?
Yeah it does man, looking at it myself
