HKS T51 SPL vs T88-38GK

[*Shane*]

would pick a hks T51 over the dinosaur T88 anyday

[waynegts]

i just got a t51rspl to use on my gts, should be fun, oh and its easy capable of 800bhp if not overkill for that power. you can produce 800bhp with a smaller turbo and have it spooling earlier

[lb23james]

Well im going for 800 at the wheels, bhp means only at the crank right?

And im really starting to look into this Borg Warner turbo but no one has made any comments.

[QUOTE=EndlessR;1196821]Id say T88-38gk for various reasons, cost, better compressor housing, we dynoed our drag GTR and made 907whp @ 2.5bar boost @ 6700rpm
Engine was HKS hideck with full tuned head.

Sounds like your engine is more than capable of producing the numbers.
Other than that I can offer you a Holset T95-R turho (Has) billet shot peened compressor wheel, 16cm housing so will spool very fast, it has inconel exhaust wheel. This will out spool T51-R + T88-GK due to the housing size, it will also make 900~1000hp depending on engine.

PM me if you want more information

Rick

how much price difference is there between the holset and the other two?

[lb23james]

Guess i'll never hear about the Borg Warner.......

You need a very good flowing head and very good engine tune on a 2.6 to make a T51 SPL work well.

yes...T51R SPL VS T88GK is like comparing the taste of swiss chocolate against poodle shit.

T51-R may perhaps spool earlier, but the T88-38GK 22cm turbo flows more.

You can`t make an opinion on ballbearing technology alone, as that is only one dimension of the matchup. T88-38GK has more exhaust blades which means = more flow. Hence why it packs a punch.

Also T88-38GK is not to be compaired with older versions of the T88-34/33d versions. Its much newer design.

Correct answer would be,
Both perform very well on the RB26, depending on tune, is you want slightly less top eng power and slightly higher spool then go for garrett, if you want more power and a bigger hit of power then go for the T88-38GK as it packs a wallop.

Or if you have some money available, try both, sell the one you dont need, but dont be put off by what people are saying about the T88-38GK, as their wrong.

[waynegts]

he only wants 800bhp tho

the T88GK falls off at the topend...they simply run out off puff. T51R SPL BB is a much better item both early and later in the rev range. This is actual real world testing on a variety of cars and engines...in big power set-ups the Trust turbo is also quite unreliable...just ask Theo Wollett (8 sec drag GTR) how many he went through before turfing it in favor of a Garrett based item. Trust turbos should stay on the vehicles they were originally designed for....low revving diesel trucks.

^ I can't speak for the NZ guys as I don't know exactly what was behind the decisions, but as an observation I do know that in the earlier days for Reece McGregor and Glenn Suckling Trust T88s were hanging off the sides of their cars, then T51Rs came along, then Reece went to big Garretts when he needed more power and Glenn TRIED a pair of Trust turbos but ended up settling on a big Garrett as well.

[R.I.P.S NZ]

No contest, T51 spl and I'll be sticking with roller Garretts.

I think we should Compare the T88-38GK to the HKS New T62R. let me say, other than the over price this Turbo is nothing but brutal power and it spools almost like theT88-38GK 22cm. but it out perform it in every aspect. when we first installed it, the housing looked so small to me i did not have the confidence but, we made 945RWHP at only 29Psi on our 2.8L Engine. now i am a believer of this turbo. but it is not a street turbo for the GTR but again it all depends on how you define street-able .

No we shouldnt, as the compressor wheel is larger on the T62-R and T51-R than they are on the T88-38gk than.

^^^ so going on them numbers how does a t88 flow more as it has smaller wheels?
