Rb 25 Turbo Choices

[Adz2332]

Hey all,

Posting on behalf of a mate.

He has a 33 GTST and has the following mods (track only car)

1000cc injectors

Power Fc

Profec 2 boost controller

Walbro E85 pump

Cam gears and cams

z32

Stripped the car completly.

Runs slicks on the rear

Looking at what turbo and what top mount manifold to use?

Plus what forward facing to use?

Will a bigger throttle body be needed?

What he is setting it up for is 1/8th mile dragging.

Hes after a turbo for excellent response and mid range power.

The engine will be rebuilt if / when it goes bang.

Not chasing any specific power goal, just decent times over the 1/8th mile

What options are there?

Only needs to pull hard from a standing start to the end of an 8th mile!

Any other mods needed to?

[wolverine]

E85 and any 450hp turbo

T67-25g 8cm housing?

T67-25g 8cm housing?

what are people using on rb25s at the strip?

[Frosty]

most cars on the strip are built for bigger power and even plenty of these street cars are the same and have much bigger setups. In yous instance you are talking 1/8th so the question has to be asked is why?

whats the point of the 1/8th? where you heading with the build?

whats quick on 1/8th is going to be usless (or just about) on 1/4

[Adz2332]

to be honest because the only venue i have to drive my car is an 1/8 mile track.

plus the car will be used for the occasional hill climb and the sorts.

So its more about response and excellent mid range, without running out of puff

Its just hard reading and getting ideas as there is nothing on here for what im looking for.

Its a strickly track only car also, so dont car about a rough idle for cams or a pig to drive etc as its out on the track a handful times a year etc etc

[Ke55pig]

you dont live near AIR im guessing then ??? they have 1/4 mile

to go with everythig else you have id go either a tdo6 or a t67(slightly laggier but cappale of almost 400rwkw)

[Adz2332]

i pretty much only will use the car for hill climbs and to go into Mallanats. thats pretty much it

thanks mate will read up on them

[GTSBoy]

To be honest, I think anything bigger than a 3071 would be too big for your aims and you'd actually be better off with a 100 shot of nitrous.

[Adz2332]

I dont like the idea of nitrous...

Will run e85

[Joshbigt62r]

Gtx3071 on e85. Plazmaman plenum with his 72mm throttle body. Should be good for 350rwkw with killer response. Nitrous is awesome set up correctly. Unsure why people dislike the idea of using it. What's a nitrous kit worth now days?

[Adz2332]

Whats mid range and top end like?

[Joshbigt62r]

I don't personally have that setup but micko on here did and from all reports pulled like a freight train all the way through. Maybe someone that actually know micko and went in it can explain more? Um I think he made 335rwkw on e85 internal gate version .82! Also on the stock mani aswell.

[Adz2332]

Whats the diff with the 56 and 82 housing?

[Adz2332]

The 76 much better top end wise?

[ARTZ]

Lol @ top end, its an 1/8 mile you wont get half way though third gear,

just get a hiflow..stock plenum and everything...it will be just as quick for what you need...

the money you save put towards your suspension setup, tyres and practice runs because that's what will make you fast...

Anyway I know nobody will take any notice of this post so potato...

[Joshbigt62r]

TOP advice if you ask me ARTZ. hiflow hypergeR turbo? Um the rear housing size .63 will fall over quicker being smaller and .82 will have more legs up top.
