Hey guys and girls,

I have a mate that has a corolla who is turbo'ing a 20V motor.(I know its not a nissan but you guys have so much tech information it overwhelms me!!) I used to own a S13 by the way lol.
Anyway, he wants a responsive turbo that can start spooling around 3000-3500rpm and which is capable of 600hp. He also wants to know if he is running this much power will the VVTI still be usuable for the power band(rev out to 8500-9000rpm) or will it be unusable or would it just not be worth the effort and just ditch it? What turbo would you guys recommend and can you comment on the VVTI question?

Thanks champs.

Kory.

on a nissan forum im probably the 1 u wana ask about toyotas.

the basic thing about your question is.. how the fuk u wana get 600 hp @ 3000 rpm from a 1600... lol.... its jus too much to ask for.

a common mod on those is a td04. and if he had intention to do turbo, he wasted his dollars on a 20v conversion. more valves wont mean more power. u can get a 2v engine to pull equal power to a 5v without any problems so he woulda been fine with the 4v 4age that can be found thousands cheaper.

the 20v is great as an NA engine as it can maintain great driveability with very high compression levels and extreme RPMS. it has been said that it could become the ultimate 4 banger if turbod altho when u look at it realisticaly theres no reason why it would be the ultimate over any other well designed twincam 1600. that and you cannot call any engine the ultimate engine without reading all about the sr's reputation on the internet, that is delivered by the gods my friend (so they say).

find out hwat ur friend really wants from the car. turboing the 20v will be alot more expensive as there are no adaptable standard parts like the ordinary 4ages have (like 4agze ecu's) the 20v is very much a different engine and has an 11:1 compression ratio.

keep it all in mind, goodluck either way

Hey mate,

Im from sydneyrollaclub so i know alot about corollas. Firstly we have researched this thoroughly and he knows this is what he wants. Im going 16V Turbo with 300fwkw and yes it is achievable. We know all about the 20v and we know more valves wont give him more power but its what he wants. He is doing GZE bottom End and 20V head. So he knows what he wants it is his money after all. He wants 350kw so what turbo would you recommend and will the VVTI work. I know this isnt the place to ask on a nissan forum but i know there is a lot of tech people on this website who know there turbos and what applications would be suitable for so i thought i might give it a stab.

Thanks for the help mate, but we also know alot about toyotas as well

His boost threshold/power figure combo is unrealistic, even if he retains the vvt and high compression of the NA 20V with the GZE block. There's no reason the vvt can't be made to work and work well and i would bet that there are a/m cams out there to suit turbo applications aswell.

I think on an engine of that size to acheive 300fwkw he is going to have to look at one of the smaller GT30 sized turbos or a big TD06 or T67 and there will be lag, and lots of it. The hks turbo of choice would have to be a 2835 but it may be a touch small to make the power. Consider that an rb25 with GT30, 9:1 compression and vvt will only makes full boost by 3500-3700 and you start to see the problem, and an rb25 moves a lot of air compared to a 4A.

For his response aims he would need to aim at something like a GT28RS/ hks2530 or a TD05-16G sized thing but would be limited to around 220fwkw but would give good response and reasonable power through the midrange.

I personally would be working on ultimate response rather than outright power, particularly if it's a street car.

Nope, no NOS mate!!! No where near it, im sure you will be guessing for a while unless BHD tells everyone. hehehe.

is it antilag ?

as BHD has mentioned your asking way too much from a 1.6 engine.

300fwkw on an engine of that size is going to be insanely laggy. nos is useless as it runs out, and antilag is no good for a street cars reliability.

besides when the things hits boost, it will wheelspin itself to death on a FW drive car... does this car have a purpose OTHER then making a number ? i honestly dont think you will be able to make that much power without jungle juice fuel. your going to need a shitload of boost running into the engine for it, so you will need to decompress the engine, making it even more laggy. and even then you will probably be reaching the edge of pump fuels ability to not detonate

what does it get used for, street, drag, circuit etc ?!

off topic, but you dont work at pennant hills do you ?

id be the one kory is asking the info about.

who says 300kw from a 1.6L is hard? its not hard at all, its just costly and insanely custom.

anyone heard of morris' blacktop 20v 330kw seca? or anyone heard of YOGI8U's turbo 20v ta22 celica?

both these well past 300kw with yogi around the 400 mark... but yes his turbo is laggy, i dont know morris' setup.

Who said this was going to be FWKW? anyone heard of a sprinter? still a bolt in job... for a 20v.

I do know alot about the engines and the cars and whats capable, i just dont know much about turbos and whats best to do that job and obviously im gunna have to search for a stronger box than an ae101 lsd too.

Its very very possible to get this with the right turbo, thats why i have turned to you guys who seem pretty knowlageable in this area as kory told me.

So is there any advice at all?

no one is disputing getting that kind of power from a 1.6L

Achieving that level of response while having that kind of power from a 1.6 is a totally different matter altogether.

Whether the power is put down via the front or rear wheels doesnt change the fact that the initial goals of:



is a dream.

My maths is not the best but 600hp (engine) is in the area of 350+Wheel KW's. Is this thing meant to be street legal as well?

S R twenty DE yo, will f**k on vtec like i f**k them hoes

not hard, but insanely costly and custom.. isnt that a contradiction ?

nope fill us in on the setup, pump fuel ?

alright going by your 600hp goal, your going to need a turbo that can push around 54lb of air
so something like this:
http://www.turbobygarrett.com/turbobyga ... T4088R.htm
or this:
http://www.turbobygarrett.com/turbobyga ... 1376_1.htm

with the latter being bigger. i dont know the HKS equivalents, they dont publish compressor maps, so you have to just go based on others experience, but i dont think anyone here uses anything that big. SAU has a few people running huge turbos there though, you may have better luck there.

Insanely custom = Hard



Why be like that on you 1st post here? I've got a good idea of what you should do with your 20V but it wont be comftable.

On another note(THIS ISNT FOR MY MATES CAR!) This is for my car. Im aiming for 300fwkw. I just want to know how laggy a GT2871R with the .86 exhaust housing would be on a 1.6L GZE with the works. Noticeably laggier like instead of 3.5K start spooling it would start spooling around 4.5K? What turbo would you guys suggest? I've looked around and this is the closest turbo i have found. Remember i want 300fwkw and a turbo rated around the 420hp mark. Dont want one too laggy but. Dont care if its rated at like 400-500hp as long as you guys dont think it would be TOO laggy on my setup thanks guys.
