I was about to say.... What are the specs on the skyline any mods?

But back on topic that evo is pretty outrageous, we down here on our lil island have a VI with 700hp+ on race gas and it is reeeeeeeeeeediculous.

His username is Crcrain, look him up and his threads im sure he has a build by build thread.

 

That is amazing! I love seeing TS results like this.

 

I havent taken it to the track yet... Not really sure when that is, I have some events for the honda coming up soon.

Basics of Engine and Fuel:
4G64
Pauter Rods
Wiseco Pistons
Cosworth Big Valve Head
HKS 280 Cams... Set at 0 (Havent even played with cam timing yet)
Magnus Street Intake

SparkTech Pro12 Ignition Setup
RC 1200cc Inj

Turbo Kit is Off The Shelf Twinscroll GT40r (4088) with a 1.06 Housing (.9 bar gate springs)

Car is on AEM and Q16 Fuel

More Pics added to 1st post.. Im not good with the camera but ill get someone to take better pics lol

 

BTW The car is REALLY REALLY FUN on the street !! The Powerband is SICK!

Also I have Full Tein Suspension with EDFC, Cusco Sway Bars, Rotara 6 Piston big brakes front and rear, etc etc

 

where did u find the black braided lines??

 

A setup like this really seems like the best route to having huge drag power and tq. with a car that would still shine on a road course and the street.

 

Looks good to me!! Looks like a great all-around streetcar too!!!

 

Thanks...
looking good and good luck with the car.

on my 40r it is a bit more laggy due to our altitude but what i will do is some
3rd gear pulls logging boost and revs..

 

whats your altitude? im really interested as i live in a high elevation area and have been thinking about this kit.

 

5600ft above sea level, one thing that i can tell you is I get 15 psi by 4000rpm no problem in 4th gear.
I will be doing a bit of road tuning today.
I will pull some logs with the zeitronix rpm vs boost.
the best thing about the Twin scrolls is they feel so different to Single Scroll turbo's off boost.

SS turbos almost feel lethargic compared to TS.
I might test out a 0.94 housing, we might not make the Topend but i am willing to trade of a bit of peak power for a wider powerband.

My car is not a drag car, roadcourse is were it will live.

 

how much for a built 4G64 motor?

 

Also what FMIC is being used on this car?

 

InDub sorry to hijack your thread i just want to post some boost curves.
I am running the same setup as you just with a 2.3 and GSC S2 cams

TwStDeVo check them out.

Show me a single scroll 35r do this......

3rd gear 4000rpm


3rd gear 4600rpm


5th gear 4000rpm
you can see we have a bit of surge going on there..
and with a 0.95 hotside i think this will make it worse


ohhhhh!! again i forget to mention 5600ft above sea level..
the 4088r is a great turbo..

also please note none of these values were inflated due to brake boosting...

 

i think that anybody who has driven big turbo singlescrolls, then drives a big turbo twinscroll will say the same thing - "why does the car with the smaller turbo have more lag" its pretty incredible how big a difference there actually is, its impossible to convey through a forum posting since you cant see it on the dyno

that is really good to see, i dont think you could reach that with any singlescroll or HTA turbo and also i dont think the smaller turbine housing is going to get you boost earlier.

our off-the-shelf horizontal flow core



i think its almost too much power to shine on a road course unless you are a REALLY skilled driver. its seriously too fast for anyone but the top 4 drivers i know to handle on a road course

most fun high power street car ive been in to date, cant wait to make our big video

haha crcain! hes on here regularly harassing us lol


the skyline is an r34 gtr, built motor, good turbo setup, etc but this is jake's thread, feel free to email me for gtr pics or specs

great points all around - only way to know is to try it. my experience is that spoolup/boost threshold and transient response may not improve with the smaller a/r. the question of how much more can the 40R compressor do is one that im always suprised to find it still has more in it, and i would say the turbine wheels runs out of steam before the compressor. i also think the 1.15 a/r is too small for the 42R.

 

nice results

what fmic are you running?
