t4 turbo, is this kit any good ?

[lord14]

well my brother has done the conversion , and spoke to many tuning companys and they've all said the same thing , we use 3 bar fuel reg's and a bigger fuel pump , 440cc injectors , 3 inch maf , 2.5inch downpipe , no oil cooler , forged pistons and rods with , t3/t4 turbo , and mapped by rtech made 404bhp and its realiable drive it to work most days . but im not sure what bottom end you have but i know the agu has been proven up to 350bhp by jabba sport and boost pipes we use 2.25 inch

i got 2.5 FMIC anyways so thats all set up, uprated pump will be 255lph walbro (in pipeline), 4BFPR cheap enough to get, could get a T3 flange welded onto that 3'' system i have, then 3'' TIP (should be easy enough)..

Bad ideas to be getting in my head, thought id be happy at 240  

Would be aiming just under 300 to keep bottom end standard..  

[lord14]

sounds about right , but i would stick with the 3bar fuel reg

Dave, another PM your way, plus you know you wont be happy till theres 1000lb off torque 

Also whats the whole issue regarding the FBR, I usually have seen 4FBR or adjustable FBR's used in these setups.

[lord14]

just alot of mapping places say use a 3fbr as the the bigger ones arent needed .unless going for massive power , jabba sport , rtech and sub 11 motorsport have all said the same sort of thing about everythink including the bottom end , i know on a agu its possible of up to 320 bhp at 17psi on standard pistons and rods

[golf-sib]

I remember the max boost is recommended at 20.58 psi, a lot of places allow a quick 21 spike or lower/restrict spike with MBC in parallel to n75 from what I remember on the stock engine.

[lord14]

yeh i know the mbc's aren't very good on the 1.8t's i seemed to of got alot of boost spiking , but with a aem boost controller its great the mapping was alot easier aswell . and alot quicker , and n75 i know they  can be mapped but personally i would get  a ebc so you can go into different modes with different boost settings and there is a over boost alarm

[Dave_IOW]

going to start buying some bits to make this happen, oil line?

Also another question, with an external wastegate, do you still have an actuator or is the external one opened with a seperate spring so doesnt need it? As the ones ive seen come with a 7psi/12psi/15psi spring etc so does this replace the need for the actuator itself?

If that is the case, where does the n75 outlet go to? A valve on the exterior wastegate?

Cheers

Believe you don't need the actuator as the screamer acts like an atmospheric DV on the exhuast gases if my knowledge serves me correct, which allows the turbo to release and spool down.

I will be heading down this road after this gentleman's experience, especially once I get my MIG welder, think the complete kit works out cheaper dave, and you can claim some money back by selling the bits you don't need like the additional FMIC, Oil cooler (worth a bit) etc... Just an idea 

[Dave_IOW]

What i was thinking tbh, once ive sold KO3s (£200ish) Forge actuator (£80?) and downpipe and sports cat (£100-£200) i should be well on the way without actually spending that much

We need to talk about TIP's golf-sib
