35r 20v 4agte

[350hp4agte]

hey guys.

I want to run a 35r instead of my t2871r basically I’m a power junkie i no allot of you guys aren’t but i am.

i have no idea how to read or even what I’m looking at in regards to compressor maps and turbine charts and all that so I’m struggling to find what 35r to use what rear housing etc

have any of you seen or had a 35r on a 4a b4

or can anyone shed some light on the subject

basically i want the most minimal lag i can with a 35r but i want to make around 400 atw

any info / feedback would be great

fatke on here had a gt35r, i believe it had a .86 rear housing, not to sure about the front tho, its a massive turbo. was meant to be for a vl to run 10s. on a 20v it will look near on the size of the motor

What spec motor do you have, internals, cams ?
What ecu are your running at the moment, and how much power you making.

Pulling 400rwkw out of a 4a, isnt going to be driver friendly.

he he he, i think i was just about to suggest you go talk to a guy who has done something kinda mad.... think his name was 350 something

anyways.... i got nothing else. forget the compressor map, just aim for what the sr guys do but work on running it to 9000 at least. wont get boost till about 5500 on a GREAT manifold.

not in a rood way, is it a dyno queen? or driven?

i have seen a MASSIVE turbo setup on a 4a with a tiny lil guy running of a wastegate screamer and some fancy plumbing. The wastgate was run full open to bring the lil fella up real quick, but he ran out of puff at 5000. by then the big fulla was just about ready to go, and a gate switched inlets then he ran to like 9500. Took ages to sort it out, and it was fairly agricultural... not shiny and not refined, but fucking hilarious to drive

hahaha na not a dyno queen man i figure I’ve got the engine hardware to run a big turbo so why not its got cams and valve springs so reving to 9000 wont be a drama

i grew up around the drags man in rotors mainly with mazfix. tim crease, grant dixon, lang racing and all those boys, i did build my car for drift but with the intension of dragging it as well. i cant see why with a .86 rear it wouldn’t spool up by around 4000

i also figure that yeh a t28 will spool up fast around 3000 rmp but it will only make power to about 6800 to say 7300 were a 35r will come in around say 4500 and make power right up to 9000 or more so i guess it just means i'll have to rev the fuck out of it. isnt that what there ment for anyway?

i reckon if your going for that kinda power from a 4a... id twin charge it.. with a .82 rear housing i dont think u will see boost untill 6000 rpm.. i had a similar turbo on an sr.. so thats an extra 400cc capacity and it had 12mm lift cams w/ adj gears and it wasnt hitting boost untill 3800... i think u should look at a differnt turbo... instead of going outright power and loosing everything else.. there may be a comp/ext housing combo and desired trim that will give u back some of your mid range. if it was just for drag then y not.. but street driven it will be a pig.

here is a comparison.
GT3037s


and your GT35(82)r


look at both specs.. the 3037 pro s is good for 525 (390 something KW) the 35r would be atleast a 600hp turbo.. so that would get u up around 450kw. TO much man!!

the 35r is way bigger in all respects.. and if u want to run the 35R with a non rediculous sized exhaust housing it has to be V band.

35R is way to big...3037 is even pushing it on a 1600cc engine.. but it would be doable i think.. u should call up GCG or the like and see if u can get a 3037proS with different trim options so's to optimise your power band.

GT35(82)r


/\/\/\/\/\ this turbo comes in a .63 rear housing nice

[Justin Holden]

GT35 is fine

Guy over in nz is running a gt35/40 make 350kw

another guy is running prescision gt30/71r making over 300kw as well

Not much lag, you jsut have to make sure your hard up it form the get go

give kent a ring on 0064 9-425 7030

He will point you in right direction

It can be done and works alot better than you would think, 4age breath easy so gettign it to spool is easy

[350hp4agte]

400hp lets get that right and cheers sundee thats sort of what i was after i dont have to go 35r i was just wanting some feed back on big turbo's or bigger turbo's than a t28 i do think 6000rpm is a bit hi tho but your opinion i'll let you have it

cheers keep it coming
