upgrade twins or driftmotion ct26

[supra8903]

ok, im going 1j soon and i need to have more power. should i upgrade the twins, to steel wheels and mitsubushi fronts. or should i use a driftmotion ct26 kit with a boss turbo, both will cost about the same. i going for 500rwhp..... any input would help.

I think those 1000+ dollar upgraded twins are a waste of money... Well, maybe waste is a bad word but that money could be used better elsewhere.

I wouldn't count on the twins, upgraded or not, getting you 500rwhp. They're still pretty small.

Not sure if you'll be able to fit a boss turbo on the CT26 adapter manifold either... You might as well go with a full manifold at that point, IMO. Aaron would know that better than me though.

Just some thoughts.

[bobiseverywhere]

if your going for 500RWHP go for the nice kit that Suprahero bought

http://www.supramania.com/forums/showthread.php?t=33957

Supra hero is putting down 446RWHP and his compression is so low its not funny. With proper compression i am quite sure he would be over 500RWHP

t3 manifold w/ a gt3076r or a gt3040 (gt3082) :)

edit: nvm you said 500whp.. regular t4 manifold and your choice of turbo (size of the turbo depending on how you want the 500whp)

[Van Diesel]

neither of those two choices will get you 500 HP without a large NOS shot.

[bigaaron]

Mike just dyno'd a 60-1 ct26 on his new 1jz with my manifold and a Stinger and it made 300whp at only 8psi! As soon as he hits 500 miles and the boost controller gets installed I think the skeptics are going to be silenced.

But it's not going to make 500whp without race gas reguardless of what turbo you run, and the gt35r would be about the right size to do it.
You will need well over 20psi, and on pump gas that's pushing it.
Although, once you have driven a 400whp 1jz I think you will be satisfied, and a 57trim ct26 should be able to do that.

[supra8903]

ok... so lets talk.... ill be running a 1j, arc intercooler, upgraded fuel(440s or 550s, regulator walbro pump).... and lets say a 57 trim, with race gas... what could be the number, would HKS cams help... I would be happy with mid 400s at the wheels, I really want to stick with somthing bolt on, because I do not trust anyone to work on my car (in in upstate NY). any input will help.

[The Reaper]

too many other factors to say it will run an X number of HP

me myself i would go with a full T4 setup ANYDAY

[The Reaper]

thats what i was thinking...67mm or bigger.

i know the GT4088 is a 65mm think it would flow 500whp on pump? with BC 272 small core cams?

[The Reaper]

i haven't seen a gt35r hit 500 on pump. i always see them in the 23-25 psi mark

maybe i'll go with a gt4088 then

i'd like to have a gt4067 but im not spending over 1K on a turbo

[The Reaper]

yea but its like damn near 1300 bucks!!!!

i can get an ITS 67 for WAY cheaper

[Van Diesel]

I'd rather have a GT4067. You gotta pay to play....and you get what you pay for.

[csnow]

.

If i didn't pay $550 for my brand new GT4088 from precision, i woulda got the 4067

You got one that cheap? Sell me yours and you can get the 4067.
Seriously, I will pay you right now.

[bigaaron]

You must not care about your engine if you run 25psi on 91 octane, or you're just ignorant of the consequences. Sure you "could" make 500whp on pump gas, but I'm not going to tell anyone to try that.

[bigaaron]

I guess you are not smart enough to know that when people talk about "pump" gas they are talking about 91 or maybe 93 octane, NOT 100 octane or 110 octane.

[drewgo]

I agree, a buddy did one and he was having problems with surging. The upgraded twins will fight each other after 14 psi.. He had it for a bit and went single.
I asked why do they work so well on the RB and it's because the RB26 has ITB. On the 2jz HKS twins they have a few tricks to make it work buts not practical if you are on a budget. It will become costly if don't do the work yourself.

[bigaaron]

100 octane and 110 octane is considered race gas whether it comes from a can or a pump, and that is directly reflected in the price. Seems to me like it's just a creative way for people to exaggerate how much horsepower their engine makes on pump gas. There are a few gas stations in my area that offer race gas......from a pump.

[The Reaper]

when i say i want 500 on pump i want 500 whp on 93 OCTANE!!! im with aaron on pump gas definition

but theoretically ALL gas is PUMP gas cause they are ALL pumped at some point or another, be it from the ground when its oil or into the truck to be transported :)

[Mr.PFloyd]

If it walks like a duck, quacks like a duck, looks like a duck, it must be a duck.
funny, thats what i would say about holset turbo's, as they do everything equally if not better then their name brand counterparts.

[csnow]

I agree, pump to me refers to 93 and below.

[The Reaper]

how are the holsets coming? anymore dynos?

[The Reaper]

and what exactly does that mean?

[bigaaron]

Something about ducks quacking.

If you want #'s on a certain octane, then ask what octane.. but otherwise.. i'll let you know what ppl have made on pump gas using the highest available octane nozzle that fits in the side of their car from a gas station.

Don't play stupid. Pump gas refers to 91-93 and you know it.

If your car had 1000rwhp and you could pump C16 from a station, would you claim you made 1000hp on pump gas? No. I hope not.

I have 100 in my tank right now that came from a pump but it's not pump gas as we use the term.

[The Reaper]

indeedage

btw Joe....im staying full 1JZ....i dogged it but spanked a vette and a 06 Roush Mustang this weekend. i actually like the powerband LOL

so i will be singling it soon :)

[Van Diesel]

well, pump gas 93 octane and water injection. That's pushing it though.

[tissimo]

too bad we dont have e85 in fl.. I would rock that and have like 600+ on 'pump' :)

[mattjk]

LOL, now you get what I was saying about the 2jz doing 13.7 at 118mph.

1jz has a wonderful powerband.

[mattjk]

GT4067? I'd get it.
have you looked into the borg warner bullseye turbos? a buddy of mine works at JE, and said he could get me a good deal on one. the largest S300 series turbo.
72mm

[tissimo]

I'm not that thrilled with the BW extended tip turbos... but not too much results on them..

[The Reaper]

tissimo is BACk in action.....

matt....i still dont see 13.7 @118.....when i seen a 2J mkiii go 12.4 @ 113 with only a 2.0 60ft. but yea i am staying 1J LOL

BW extended tip wtf?

[Van Diesel]

it's borg warner technology. They have an explaination on what the BW extended tip is.

[suprahero]

I wish I could get some 100 octane around here, but we're stuck in the stone ages and 93 octane is all I can get at a station. I'm sure I could make over 500 then, but I still think I"ve got a timing issue since I'm pulling so much fuel with my safcII. My car is running awesome, but it could probably run better.............:dunno:

[csnow]

Get a bigger turbo. I think they have those in Alabama. Maybe not :)

[Van Diesel]

93 octane + water injection. I'll be going this route.

[bigaaron]

Jay doesn't need a bigger turbo, he needs to pick up a can of race gas from the local speed shop and run more boost!

[OneJoeZee]

The proper term is crack fuel. I will be sad to term the boost back down when this tank runs out. :( I need more!

Cocaine's a helluva drug...

[csnow]

Run Meth. Cheap crack for ya.

[The Reaper]

man those Bullseye turbos are EXPENSIVE!!! are they BB???

a 66mm the S366 is friggin 1500 bucks!!!!!!

i'll stick to my GT4088 or ITS67

hell i'd rather get a GT4067 for that price

[mattjk]

yeah, i can get the S366 for 950.

[The Reaper]

but still thats 950 for a 66mm when you can get a 67 for cheaper

i wonder how the spool is on them?

[mattjk]

well, he said 950 for any s300 or s400 series. spool is claimed to be better because of the extended tips.

[Spaniard]

About 4 years ago when I had started my 1JZ project, I said that the CT-26 or CT Upgraded would be an ideal turbo for the 1JZ with a y-pipe from the stock manifolds. Everyone told me I was wrong and that I was young and stupid. Grrr!


Mike just dyno'd a 60-1 ct26 on his new 1jz with my manifold and a Stinger and it made 300whp at only 8psi! As soon as he hits 500 miles and the boost controller gets installed I think the skeptics are going to be silenced.

But it's not going to make 500whp without race gas reguardless of what turbo you run, and the gt35r would be about the right size to do it.
You will need well over 20psi, and on pump gas that's pushing it.
Although, once you have driven a 400whp 1jz I think you will be satisfied, and a 57trim ct26 should be able to do that.

[Spaniard]

GT-35R is a great street turbo even on pump. But way better on high octane. If the goal is 500hp on pump GT4088 is the best bet. Personnaly I'm going AMS GT-37R turbo can you say 500hp pump with a Gt-35R spool?



i haven't seen a gt35r hit 500 on pump. i always see them in the 23-25 psi mark

maybe i'll go with a gt4088 then

i'd like to have a gt4067 but im not spending over 1K on a turbo

[tissimo]

well, he said 950 for any s300 or s400 series. spool is claimed to be better because of the extended tips.
from what I've seen usually slower.. due to heavy wheels & larger shafts.. the hype isnt there as far as power from what i've seen.. the 66mm ones from what I've seen (look like 2-3 months back) was making on par power with a 67..

[The Reaper]

so they are about even then....but may be more laggy due to shaft and wheel size?

owell i dont care i'm prolly going with an ITS 67 like you had justin or a GT4088

[fstlane88]

What 'd that guy with the 60-1 CT end up making, anybody know?

[SuprA70]

I made ~300rwhp @ 8 psi... this was during the 1JZ's break-in period. However, in my haste, I made the mistake of just reusing the same turbo (which was freshly rebuilt) from when I originally rebuilt my 7M.

It blew a mere month later after being run at 21psi (constant abuse :evil2:) for about a week. I was supposed to dyno that following Saturday.

I've since decided to go with a newly rebuilt 57 trim, so we'll see how it does when I get scheduled back for some quality time on the dyno :biglaugh:

I'm not shooting for more than 400+ for now, so the upgraded ct26 is sufficient.

[HIDPLANET]

Good one there Forrest... :naughty:

The turbo you made 300 with, was that on a stock CT one or upgraded? How'd that 21 psi feel?:evil2:

That was on a 60-1 ct26... 300rwhp @ 8 psi. It's a rebuilt, high compression, overbored 1JZ running on the Stinger standalone.

21+ psi is the most I've ever pushed my ct26, on either 7M or 1JZ. Let's just say 20+ psi for me is now the new "stock" boost :evil2:

[drewgo]

GT35R's can do damn near close to 500whp on pump, so i don't see why a GT4088 can't

agree with RIC I got a GT4082 and made 485 on pump. No cams just stock block and head with a SAFC. I am getting a retune and will most likely break 500 with no problem.
So a 4088 will do that and more.

[Ckanderson]

If you want #'s on a certain octane, then ask what octane.. but otherwise.. i'll let you know what ppl have made on pump gas using the highest available octane nozzle that fits in the side of their car from a gas station.


Ric, quit being an idiot.

[1jzMoe]

all i have to say is that the twins aren't worth it

[bigaaron]

A gt40xx really isn't a fair comparison, those turbos alone cost more then my whole kit including a upgraded ct26. Add in a downpipe and intake and you're still under the price of the gt35r turbo.
