Looking into changing out the T38 that is on my cossie motor for a T4 Roller Bearing.

Now i have concerns about lag and the likes as i have never driven a car with one of these "modern day T4's" fitted

What they like?

Going to be on a Low Comp engine with Exh Cam, Siemens, MSD L8 etc etc.

Opinions please.

Cheers

 

Heard loads of people say they're less laggy than a t38 paul.

 

Mine was less laggy than my t38

 

Cheers guys

I think I can see into the future and my wallet is looking a little thin

 

I think Euans was on full boost by 3500? my 200sx is on full boost by 4K on a cossie T4 non roller bearing, altho hopefully be roller bearing'd up soon which will be interesting

 

Think alot of it has to do with spec and cam timing as mine was fairly laggy on the road, when it did spool up it came on hard.

 

i got out with blacky in wennys mk 3 when it was roller t4 spec ,

the thing built revs like a sportsbike ,and when it hit boost i wet meself


deffo a turbo im looking into


beef

 

paul i can help your wallet! sell me the car! getting fed up the the type r now! its too reliable! even with the big injectors and mr forrest map! its no fun knowing it will start every morning! think i really need another ford!

 

just out of interest; why a rb t4? have you looked into the gt series?

what bhp you looking for?

 

Have heard good things about them.
Not looked into the GT series.

bhp is not that big an issue witm me as i am building the engine for good quick strong spool up so high bhp figures are just an added bonus.

It made 477bhp / 422Lbft in it's current guise on Norris Design's dyno last time but i have changed a few bits so just fancy the RB T4 to compliment the changes.

 

RB T4's are pricey compared with GT's

look at the gt3076's you can import them from the US; not sure how it equates with current exchange rates tho
