well i bought a Turbo for my RB25/30DET its a TO4B A/R 1.00 and i think an H3-Trim on Comp wheel and O-Trim on the turbine i have been told by some people that the A/R is to big at 1.00 but then i was told with the twincam head it should be good. i am asking wat opinions do you guys think. its external wastegated type.

1.00 will be sweet man

worked like a charm when i had my single cam, especially with a jpc stage 1 cam. drove like your stock vlt, nearly.

Ok sweet as what size would be to big for the Rb30??

how much did you pay for it? Ive got a T04b with .86 rear.

Anything bigger than what you've got hybridvl would be laggier on your motor. so sounds like 1.00 is fine.

i paid $800 brand new from sum1 who didnt use it. i guess u could find them cheaper if u tried but i was happy with the price.

I got a turbonetics T60-1/T04B brand new for $1250 with 12 months warranty. Has the same rear A/R as yours and lag is not as bad as I thought it would be, quite the opposite actually

Ok kool yer my exhaust housing is also split pulse.

the front wheel/housing will play a role when it comes to lag, bigger front wheel/housing will make the turbo more laggy. Also i don't see the point in running an o-trim wheel on a 1.00 rear housing, i would have used a smaller rear housing and even if it doesn't flow as good it will be alot more streetable.

so what ur saying is to have a smaller Front wheel??? or a smaller rear housing? i was thinking of getting it hi flowed later on with a bigger inlet and wheel is this a good move??

You've spent $800 on an old skool T04, then you want to spend more high flowing it and putting on bigger wheels????? For $2000 you could have bought a GT30 which will flow 550hp+ and spool up @1800rpm!!!

Large exhaust housings have many benifits, low EGT, low back pressure, and good high rpm power. On the down side, the rpm to spool is generally higher. I think the H3 wheel is fairly small, the V, or V2 wheel may be a better choice.

ok kool no worries yer i spent $800 but i did say i was thinking of hi flowing it didnt say i was.

If I Had That Turbo I Would Machine The Front Housing To Suit A V2 Comp Wheel And Get A V2 Installed, Also I Would Pull The Rear Housing Off Ur Standard Turbo And Get It Machined To Suit The O-trim Turbine Wheel On Your New Turbo Soit Will Be A Direct Bolt Up( Bolt Up To The Standard Ex.manafold And Turbo Dump Pipe, You Won't Need To Use An External Wastegate And U Can Use The Same Oil Feed/retern Lines.)

in that case you may aswell hiflow the old to3 and sell the to4

Nah the T03 i had was from a Rb20DET which is a really crappy T03 i was told not 2 waste my time with it. im sure i can already use all my old oil lines and also the turbo has a T03 flange and not a T04 flange.

Hybrid Vl: are u using the RB20DET computer and loom to run your beast?? just curiuos...

nah mate i am using a Microtech MT8.

Also, what specs and what power will it hold?
