Hi
i would like to hear from any body who has any experience with the GT42/45 in terms of

how it would work on a fd with a 1/2 bridge,

how well dose it spoll up,

how much boost is needed for it to produce 500 plus rwhp.

and also will it fit.

cheers

Erdin

 

Would'nt you be better with a 35/40 for 500rwhp or a T51Kia.

From what i've seen the 42/45 looks like a 20b turbo and will take some cutting and messing about to get it into a FD engine bay.

Have a look around on here for a guy called Alf (Soul Assasin) he ran a To4R at 520rwhp on a Half Bridge before he went on to his Full Bridge T51 engine.

Bridges are a Very capable type of Porting but to get Big hp you may need to run big Boost and Race Fuel.

ok iv spoken to marco and iam seriously considering this turbo but i will have to fabricat a manifold for it to fit properly. come on guys is there any think els that i need to know befor i go out and spend, come on i want all your thoughts.

 

173 views and nobody hasent got anthink to say come on i need more info from people that have used this turbo what do u think of it

 

I think it's a great turbo. Thats why i got one. I haven't installed it yet but i'll let you know as soon as i do.

 

It's because a total of 4 people here in North America have one (only 1 with a half bridge), with a few more in Australia (maybe).

None of these people are on the forum. Do you want guessing and uninformed info? If you search on GT42 you will see a lot of guessing and naysaying, but only one factual story source for information from someone who has actually tried it.

Be glad your question hasn't drawn some of the usual responses. It's not exactly the most common turbo in use, ya know!

 

Speak to Geof at Reworks, they have one there fitting to a 20B.

Belive me its a big Turbo.
