Big Arse Turbos

[kg]

Anybody out there fitted a T78 or T88 Turbo? Thinking about it for an upgrade and would like to know about bhp, box & clutch upgrade, lag, general driveabliity, fuel consumption and such. Let the good times roll......

[strutto]

Errr... What car?

My mate has got a T78 on his R33 (currently for sale). He has around 500rwhp. Not sure when it comes on but being a large turbo its a little laggy but the top end is awesome. He has had a heavy duty clutch fitted so driveability is fine and the box is holding up so far. Not sure on fuel consumption but very reasonable from what i have heard.

Not really enouth info concerning your current set up (stock internals/mods etc), type of car, power aim, how much MONEY you have budgeted (in any case take a figure you think will cover it and double it).

laggy and shit o drive but heaps of power when you get to 6.5 k

Drrrrrrrrrrrrrr, R33 GTR VSPEC

Stock as internals, usual basic upgrades – airpods, exhaust, Apexi..............

DR as in DR GTR not bad y go big high mount cops are goning to f*&ked over the coming months i would just go low mounts big ones 4 simlier power u would have to look at upgrading internals 4 ethier T78 or T88 and T51R SPL and a least a cross missoin gear set

ask theo, hes got a t88 on a 32 gtr

[siksII]

get twin low mounts, gtss's, 2530s or N1s

the only big turbo car ive been is a gts-t with a t67(large exhaust housing)..

that car had stock internals and pulled 340rwkw on about 1.2bar... anyway it had cams a/f int plenum, flowed head etc came on full boost about 4500 but had useful boost at around 4000...

the car wasnt that good for everyday useable power.. lots of top end.

got a t88 on my gtr and it doesnt make power till about 5000 . not that much fun to drive unless you are after max power for drags.

abflug: I guess thats your car in the latest HPI edition?

Big turbo's = Boring

The hardest thing to do is create a responsive engine with flatline or progressive torque.

Dual sequential turbo's are by far, the smarter choice in terms of drivability and top end performance.

Its simply wank factor to have a stock engine with a shiny t88

[offtopic] Yes, but why would you rid the RB26 of its true-twin set up (by true-twin I mean non-sequential, i.e. both turbos spool and produce +pressure (boost) at the same time) setup in favour of a sequential twin setup? Sequential systems are good in theory, but by having the huffers sharing the same exhaust manifold, they suffer from the "gate" (for lack of a better word) that switches between the small and large huffers being jammed or stuck, rendering the sequential setup partially useless..Examples are FD series RX-7s and JZA80 series Supras [/offtopic]
