t70 on sr

[ExtremeD]

i can basically get a brand new t70 .70, .84 housing with i think its 64 trim. anyways.. my buddy it almost giving me this and i had read afew posts about people asking about them, but i was wondering if anyone has actually put one on there sr? i wanted to know the rpm it starts to boost at. and how it does as a daily driver. i drive my car hard so keep that in mind. and i was wondering if a 2 gen rx-7 turbo would fit on a stock mani.
thanks

[wonkuuzenki]

T3 or T4?
sorry for the fucking ignorant question.

[ExtremeD]

well it says it a t3 right on it. so it would be t3 flanged right?

[zoototheyork]

get a compresor map (search button) that will give you all the info

[ExtremeD]

i dont really know how to read it...im dumb i know!! but wouldnt it be diff for the diff size motors? http://www.turbocharged.com/catalog/compmaps/t70.html
so its saying its starts at like 2, that just doesnt seem right for a big ass turbo.

[projectdrifter]

i would think a t70 would be a t4 based turbo. my t67 is a t4.
it would need supporting modds. cams,intake manifold,fuel,ecu/standalone,clutch/flywheel, just a ton of mods. if it was a rhd car u would have a lil more room but with a t4 based turbo and thee steering and brake master cyl u have like very very little room to get a big turbo. a custom tubular or a very well planned log style would be in order. unless u are fully built and have a daily driver i would not recommend it as a daily.

[ExtremeD]

well im sure its t4 based but the flange is t3. but i have already planned on cams, port and polish, top mount mani and fuel. but when does your turbo spool and whats the ar.

[420sx]

is there a reason you want to go so fucking big? its going to lag hardcore

are you building the car for drag racing?

make sure it's paired with a T4 housing.

Dont go larger than 264 on cams.

Run a stock intake manifold if you looking for sub 500whp.

Greddy will exacurbate the lag.

If i were you I would get a t67/t3 BB if your looking for that much air.

[ripnbst]

A T77 seems giant for a 2.0L motor, lag would be ridiculous. Are you stroked to any more displacement? The better question than what RPM do you start boosting/spooling would be at what RPM do you reach full boost? Running a snail like that in a car weighing what a 240 does traction is going to be a mess. Running something like that in a daily driven 240 is sraight up retarded. Its not a very streetable setup. I would say the only thing that would be good for is drag and highway runs. No drifting or road racing for you, tight~moderately tight corner exit acceleration would be garbage and you would be hard pressed to keep it in boost while sliding around the track. Supras take a while spooling T88's which are in the same ballpark as the turbo you are asking about.

[steve shadows]

yeah your going to hate your life.

Ive driven all kinds of oversized turbos on sr20s, go with a gt30 or gt35 series

[ExtremeD]

lol well im getting it really cheap but my friends wants to trade me his gt35 for it so i think im going to do that. hes building a 600-800hp honda.

[ixfxi]

dude...... do it

at 20, every decision u make is a good one

[steve shadows]

dude...... do it

at 20, every decision u make is a good one

lol

I made the 62-1 (thats a turbo fyi) Decision at 20, it was horrible, ran an 11 but it was still horrible the car was a pile of shit. :doh:

[azndoc]

Holy lag batman!!!

[ExtremeD]

i traded my friend and its actually more like a gt30r, and i got a top mount mani and everything but then i ran into a little prob! the housing slightly hit my brake master cylnder, and the lines are in the way so i wouldnt be able to run a down pipe. and its v band flanged. now im not sure what to do. the housing is 69 a/r with a70 a/r inlet. is there a smaller brake booster that i can out on it, or find a smaller housing or should i just sell oe trade it for something else?

[Wahl 136]

If your getting it so cheap why not use the money you would spend on supporting mods get a Gt2871r for alittle over 1k and push 300-350 whp all day for cheap. Good STREETABLE hp.

600-800 hp with his honda, apparently he just wanted to leave himself with 200 hp difference in leeway?

I wish I had problems like that with my builds.

the housing slightly hit my brake master cylnder

Your f'ed if it's that close your going to melt your brake and clutch reservoirs. Is it really worth all the shit to say your running such a big turbo? Or are you going for shock value here?

[sideview_180sx]

go to JGStools and get the pieces so you can redo the log mani away from the master cylinder. or save up and go full-race mani.bahhhlllin !!!!

Why? The only way to use the turbo to it's full potential is to run 270's or higher. That turbo aint making any power in the powerband of a cam smaller than 270..

[Mazworx]

Why is everyone on here scare of big turbos? Has anyone driven a properly built SR with a big turbo? People always misuse the term turbo lag. If you know where your power band is at, then you drive accordingly. We run a GT42R and that thing responds very well. After the season is over, we are going to test out a GT45R. I'd have to admit, the car does get a little crazy on the street, but there's ways of settling it down.

I was going to say the same thing. 264 is pretty mild. If I keep my sr im going 272in/ex on a .86 2871.

Cause nobody else does.... So the majority throw it out the window as impossible.

I love big turbos....

Thats why people hate me on here.

Depends on what he is doing but the gt series is a whole different breed imo than a straight t4-t70 turbo.

I mean the t61 was not seeeing full spool up until 5200 with 272 cams.

GT35R is the largest I would go for an sr on the street.

For a race car that only sees aggressive tunes and race gas.

Sure give me a divided gt4088r

He's not lying i've seen this man's set up in person. the old set up about a yaer ago that is. I think it has inproved. but this guy is THE MAN. :bigok: big turbo steve.

[ExtremeD]

my cams that im getting are 272's so im good on cams right. whats the a/r on your 61. like the a/r on mine is 70a/r compresser and 68a/r housing. what is going to be the spool range with those cams and port/polish?

[Koopa Troopa]

Don't waste time with HKS cams...

I like the comment about the 300-350 being good "streetable" power.. If you go to the local drag spot sunday nights with a 300-350 hp SR kei cars are gonna be giving you a run for your money... :rofl:

I swear koopa, you need to go back stateside so you can realize that not everybody fucking drag races...:loco:

[Koopa Troopa]

I don't even drag race..... Last time I went drag racing was when I had the 180... T25, 256 cams and bald tires and I was lining up against 600 p/s 32 GTR's with two-step's. LMAO.... That dude was gone before I got out of 1st..

Me go stateside? Never!

[projectdrifter]

well i hope with a t70 he plans on drag racing or time attack.. it would be a very useless setup for auto cross or drifting.

On my T61/T3

I had a .63 t3 turbine housing...

If I were you I would stock to the .68 T4 you have and the 272s will complement it better.

The only thing you will be left in desire of

(other constantly running race gas forever because its so much faster and more fun with so much air)

is a higher redline or effective rev range.

I would seriously consider solid lifers and straight cut gears to match this set up more appropriately.

Then shift at 8700rpms and your good to go. :wiggle:

[Hailtothesilvia]

i've driven a supra w/ T66 and the lag was pretty un-bearable

T70 on 2.0??

no drifting, auto x, or roadrace for you

[ExtremeD]

sweet deal man, i wont be using the t70 i traded that for the one i have now. and the hks cams, a dude i know said he was going to sell me the cams, springs and i think some retainers for 600. so i was going to jump all over it. and i dont do much drag either except every once and while when some car gets a hair up its ass and thinks there fast. but there arent alot of fast cars in my town. most of the fast cars are muscle. but on the cams, if not hks then who?

[ExtremeD]

that last post went to steve by the way

[steve shadows]

Just keep in mind it will be laggy.

Very laggy compared to a .63 t3 housing, but better than any other t4 housing you could grab.

If you don tmind me asking -unless i missed it.

what is the turbine wheel spec?

P trim is a great wheel for a smaller comp wheel, o trim is better paired with what you have but again big wheels = more lag, but balancing trim on both sides is usually better yielding to spool and power.

This is why people choost the gt35r over the gt3040r now. 35R wheel is newer better design but larger yeilds slightly better spool.

Try it out and if its a crap shoot sell it on a supra forum and go with a T61.T4 you wont be upset.

[ExtremeD]

im not really sure what the trim is, i can run the numbers and see. but that turbo is about the same size as a gt35 right, just incase i do deside to sell it.

As far as the HKS cams go, what specs? If it aint atleast a step 2, with high duration, theres no point of getting it cuz it wont do jack shiet for that turbo. Tomei Poncams would be your bet or some JWT C3 race cams for a fully built head with solid lifters, custom valves, and COMP Valve Springs. :rawk:

[Koopa Troopa]

HKS cams are weak.... High duration, low lift and very little overlap.. Fuck that.

You'll want to open up the ports on the head, solid lifters, double valve springs and some cams with a high duration, high lift. Otherwise you'll never have a powerband that could use that turbo...

With a balanced crank and that head and some other mics. parts you'll be able to rev to 10K with no worries.... You won't make shit for power before 5k but you'll make 500+ from 5k - 10K.

Koopa, Step 2 HKS has a decent 11.5 lift, still not that great considering the size of this damn turbo. The JWT C3 "race" cams are probably the largest cams ive ever seen for SRs. Atleast on paper its great...
