Reckon my wife could squeeze a RB25 DET into a RB20 engine bay???

Anybody ever done it?

How easy do u reckon it would be for her???

Dont ask me... nothing to do with me ..... she's insane me thinks...

ho hum anyway, just let the loon get on with it a!!

Why not an SR20DET, surely there's room for one of those and plenty of potential for tuning too?

 

[jrpidgeon]

It will bolt straight in. The RB20 block is exactly the same length and width as the RB25 (and uses the same mountings). There both 6 cylinder engines. The SR20DET will not bolt straight in, you have to change the front subrfame and gearbox for it to fit. Sounds like a good project though best of luck with it.

BTW- Why not fit the RB26 ?.

As Jason says, RB20 and RB25 are same length etc.

Maybe an idea to get the loom as well, cos they aint the same.

As for the gearbox - well, an RB will bolt up to an SR box, so in theory, the RB box would bolt up to the SR...

 

[jrpidgeon]

Interesting what you said about the gearbox Matt. Kind of wish you haden't said that now - gives me ideas!

Where abouts are you?, I'd like to come up and have a look at your install (if thats ok).

Jason.

Hiya mate. Ill PM you about my location....

As for the gearbox - well, Abbey have just fitted an RB26DETT into an S14 so Mark tells me. They bolted it up to an SR20DET box!

Speakin to **** Stanic at Sub-Zero (where I got the plenum from) he says if you're planning on running much over 400bhp in an SR20, use the RB25DET box as it'll take 500 + bhp.

 

[Draxx]

Thanks for that, and Jasn as for letting her have the RB26DETT there are two chances, not only due to the cash factor theres also the power factor, as in struggle, ie if she fits that, I will have to shell out on a GTR engine for my 32 GTS4, cant let here have more horses now can I?????

Any Ideas on how much the engines are, with the looms and turbo/intercooler??? I have none, thought the best bet would be to purchase a wrecked 33 from somewhere, but dunno......

I knew of a guy who wanted £1600 for the lump, box, ecu, loom etc delivered.
Dont know if its still available. Think it was somewhere around Leeds. Maybe worth a look.
In the end I found one down south so I went for that one....

[G-sport]

me too

I'm just starting this very project now but i'm using an Rb25de motor, looms the same as my rb20 so no probs there and I have a Power FC.
The conversion isn't that difficult, my biggest problem is if i should use the rb26 bottm end as i have a mutha of a T04 going in the car too. Are you aware that 400bhp is possible with the rb20 motor ?

Garth.

 

[Matt_S]

Dont see why not, but it would cost you....

SR20's can push 400+ (over 600 in Japan) so in theory art least, 400 should be possible. Obviously you'd be looking at splitting the engine and replacing some cast items for forged ones...

Engine Change

The boys downunder have undertaken this transformation several times, they can tell you whats involved.

Cynical answer.....

....Hi there Draxx (and Missus)

.......as you know, I faced the same dilemma with the same car
...so I weighed up the cost of sourcing an RB25DET with ancilliaries, and time off the road.....and not forgetting my lack of adventure and mechanical ability....and came up with a plan....
1. sell Skyline
2. Buy turbo Skyline

...and boy, it worked first time ...and you can do it for £2k...
(kinda what you did too)

take care all...
Jon.

 

[MattPayne]

Now then Jon... wheres the fun in that!!!

 

[Tinduck Racing]

Fun? Fun?......oh, I remember that........putting Cossie Turbo in MK2 Escort......just for fun......
.....long summer nights at Maccy Ds....that was fun.....
....5 car formation drifting on the ring road.....that was fun...


....now I decorate. and stay in. and save for the mortgage.

God I'm depressed now....
