SR20DET Transmission Options

[Redline240]

Ok from the little searching i've done (not a lot of time on my hands) i've read that the transmission is pretty weak over 450rwhp. First off, is that correct? So what options do we have after that point? I don't know much about transmissions so i don't know what could be replaced or strenthed so any insight would be helpful. I also read about a transmission that HKS makes that could be used and it's like 6 grand, is that right? kinda pricy isn't it?

That is correct, your next option would be a RB25DET transmission, its the "poor man's" alternative to a high priced "race" transmission. Enjoy your day!

I got my OS Giken Close Ratio Transmission for about $650. (used of course)

Brand new, the gear set alone is about $2000. You also need an output shaft which is about $500. Add the cost of new synchros, seals, whatever else you need.

Look at that... you're halfway to buying a full dog transmission from Quaife. (~$7000 iirc)

Actually, the HKS transmission is more like 9 or 10 grand.

Code: Select all

1603-RN010 MANUAL TRANSMISSION 5-SPD RPS13 $8,930.00 1603-RN012 MANUAL TRANSMISSION 6-SPD RPS13 $9,800.00

How much hp can it handle? Is it a bolt on or does it require custom work? And do you sell it, if so how much? If not, where can i get one, and how much? thanks

Quote »Actually, the HKS transmission is more like 9 or 10 grand.[/quote]And who do you think makes the HKS transmission? HKS? Yeah right. It's made by Quaife in america, shipped to japan, then sold by HKS. You want to ship it back over again? Just go to the source.

Many of the japanese tuning companies don't make their own stuff... especially transmissions, you'd need a transmission company to make one, right? So they get it from one of the best. Quaife.

[Redline240]

How much does the Quaife sell for?

[1bad180sx]

about 7 grand.

chill man.He asked about the HKS transmission in his original post, so I corrected the price that he quoted. I never said anything about HKS actually making their transmission.

So once again, anyone know where i could get a RB25DET transmission? it's not like i'm gonna find one in a scrap yard...

[Daunttless]

I'll probably be importing extra ones.

any chance of you selling them with the SR? some kinda combo or something? just a thought

I was just wondering but are you going to be building a drag car? Or are you going for the ultimate street car?

[Redline240]

not into drag racing that much, more of a ultimate street car.....i'd love to exceed 500rwhp.....that's my long term goal, maybe once i get enough into it i'll strip it and race it.....i figure theres no need in getting something i'm gonna replace anyway, so when i upgrade my turbo i'm gonna have to replace internals and sleeve the block as well so if i take care of the transmission now thats one less expense when i get a new turbo....probally a T66, and N20 to reduce lag....it's all on paper now, may not happen for a few years, but i'd rather prepare it for the big numbers now.....and yeah i know it's gonna cost a fortune.....

[Ace]

Yeah if you could make a deal to get a Skyline transmission instead of a SR20det then you would be set without having to buy another transmission. Good luck with your car.

[Daunttless]

I doubt I'll offer it as a package unless I'm building the motor to 400hp+ as well. : ) As much as I'd love to have a bunch of manual transmissions without bellhousings sitting around, thats not really my thing. : )

[Redline240]

It was worth a try....any idea on how much you'll be selling them for?

[Daunttless]

No idea at this point. : (
