[rb26s13]

Hey all just wondering how laggy the setup actualy is been offered t88, mani and gate for a reasonable price am contemplating it.. just would like to know how laggy it will be before i think about it

There are many types of T88.

We use the smallest one the T88-33D. The power of the Big single is hard to beat.

we are currently making 395AWKW on 22psi.

I suggest you have a rebuilt motor so you can take full advantage of that turbo.

even with say 400 awkw the lag you get over small twins, it might not be worth it.

We are going to see if we can bump to power up to 500awkw.

The power band get mover much higher into the rev range with a T88 so just remember unless you have a good motor(low lev limiter) your power band will be smaller.

The fastest circut GTR in Japan Runs a T88-33D.

I 2.8L would be good with the T88 range or massive revs.

Either way they are great turbo to use.

A mate of mine is putting a T88-38GK on a 4L V8 so it will be interesting to see how that goes.

Just one other thing people say they have lag, our car makes stock GTR power 160kw then it goes mad at about the 5k mark.

Cheers

it will be goin on a stock motor to start with.. am slowly building up a new motor.. but yer i just blew up the stock turbos and would prefer to only pay for turbos or a turbo once and once only..

im unsure of which spec t88 it is will have to find out tho

but yer 5000-5500rpm lag isnt that bad as rev limit would be set at around 8500-9000 to make some use out of it on the motor thats in there

oh yer if its makind half decent kw off boost seeing as its in a silvia would go allright.. come to think of it 160kw is more than wat a sr makes with stock turbo and a few small mods...

9000rpm with a stock bottom end is not going to last very long.

I think it is widely accepted that over 350rwkw you are cheating death an rb26. The older it is the more you have to be worried about.

You will also definitely need a power fc so the car will start and run and injectors, cams and fuel pump to make any sort of efficient use of the turbo.

^^^ i know all of that.

i dont really wanna push the stock bottom end past 300rwkw

basicaly.. i wanna buy turbos once would prefer not to buy twice

"9000rpm with a stock bottom end is not going to last very long... The older it is the more you have to be worried about..."

Strategy wise...I like your idea, big arse turboed RB in an S13, but tactically... I think your heading down a path of pain.

That sort of turbo with that sort of potential going on stock combo reving to 9K doesnt sound good. To make it worth while I would have thought collecting the parts...N1 block, stroker kit (or not) or suitable crank, quality pumps etc would be the way to go, when thats done build it along with the g'box your going to need and then sell the still intact RB26.

Buy some 2860r Garretts and sell them at a respectable loss when the time comes.

Good luck rb26s13

I think he means he will put the turbo on the stock motor but not push it till the built motor goes in

[discopotato03]

You could also look into TO4Z's and Garretts GT4088R , more modern wheel and housing designs at least in the 4088R . TO4R wheel pretty good too .

TO4Z very popular , can stay bellow the trashed engine end of the rev range and make more than respectable power . Used std engines in high states of tune often end up in the scrap bin .

Whats the transmission and wheel/tyre budget like ?

I had a t88-33d on my 25, was on full boost just after 5, with stock cams & head. Awesome turbo, if your getting it cheap go for it. I was making around 450rwhp on 22psi.

read below.. and also... i have tendancy to "collect" not pull off and sell

i was wondering if anyone had seen that part of the post...

i was seriously considering a HKS T04z kit however.. my turbo's have blown at the wrong time for me as i only just got the f**king thing goin again.

eitherway it looks like i'll probaly be slide to highflow and steel wheel the stock r32 turbo's.. seeing as i just cant afford to do the single conversion at this point in time so well yer will be good to see how the highflowed stockers go..

also this way i can get the hks t04z later down the track when i want it and not loose out to much on the stock highflows if i'd even get rid of them.

[rb26s13]

oh yer.. price i got it offered to me for was roughly 3000 for T88 stainless manifold.. and a turbonetics 42mm race gate all items new.

[discopotato03]

I think I'd put the money into 2530's or the Garrett marketed equivalent GT2860 . These will sell later more easily than dinosaur bush bearing hi flows and may work better than you think . 5000+ boost threshold is terrible in any street car , highly impracticle IMO . Dyno numbers are one thing but precious few drive dyno's for a living .

Sorry if I sound sarcastic but I can't see the draw to such a high state of tune when the power can be had in a more usable rev range . Big revs mean high wear and tear and bucket loads of money to make the transmission survive . I cannot see how rear wheel drive in an S13 (let alone the S13 chassis) can make use of the power you are talking about .

Still to each their own .

I agree with the above statement!!

If you asked me for my opinion, I would tell you to buy the turbo kit and when the time comes to building your motor go the 3ltr route. There are a few (very fast) track cars in Japan running 3ltr bottom end with the T88-33D.

i doubt the highflows will be all that much laggier than stock.. they will only be small highflows nothing big.. so im not fussed.. also i'd like to go 2530's but.. for the price of the highflows i am not fussed they will do the job.. if they get me 300rwkw i'll be happy, if not i'll still be happy that there are steel wheeled turbo's there not ceramic.

i will never be goin 3litre in the silvia.. i want to retain the factory bonnet and if i go 3litre.. means i have to make a hole and adapt some sort of scoop/bump to it.. i like the stock bonnet.

[rb26s13]

oh yer.. my stock turbo's werent that laggy at all.. i had 10psi at a smidge over 3000rpm...

[fatz]

if you place your engine right you canget away with 3 litre and just cutting the reo out of the engine

only reason i have a bonnet scoup is cause i have the single cam head on at the moment

[rb26s13]

engine is dropped as low.. as low as i wanted to go with it anyway.. there is about 5mm between the sump and crossmember
