I know a GT35R is the best to use for a turbo set up, but is it possible to fit other turbos? I'm thinking it would be a nightmare, but would you get more gains out of another turbo set up.

 

GT35R is a nice turbo period....yes you would get better gains with some other turbos I'm sure, not a smaller one but a bigger one such as a GT40R or something but still it has already been seen that the GT35R is a perfect Turbo for the j32 powerplant and has a hp rating of like 600 or so.

 

^^^ what he said.

The only reason you might use another turbo is for money reasons, as the GT35R is ~$1500, and if you used anything cheaper like a smaller turbo you'd endup with less power overall. It would probably be able to supply a pretty good amount of power up till about 4500 rpms then start running out of breath so to speak and not be able to keep the boost up enough.

of course if you are just looking to get more power down low in the rpms and don't plan on redlinning it then a smaller turbo wouldn't be much of a problem.

 

Could you even set up a custom twin turbo style setup with something smaller than a GT35R? I wouldn't know the logistics of this or if it would be worth the effort. I know for sure a GT40 = new transmission even with a manual.

 

I'm sure you can do a setup for a twin turbo but what would be the purpose? Trust me, space is very limited even with moving the battery to the trunk. There is a guy on the V6performance.net forums that was doing a twin turbo kit on his 7gen 6 speed accord, don't know how it turned out though. Usually that actual purpose for it is to reduce lag but to my knowledge, none of the turbo cars have it. You might even be able ot use the GT30R or GT32R also.

 

Well first we would like to know what your goals are. Lets start with numbers. 300, 350, 400 hp? and where would you like your power range to be? Low, mid, high? what kind of driving do you plan on doing? Daily, Road/race, Drag? If you could give us this information i will be glad to help you out. You may want to look into this turbocharger here

This unit has similar charachteristics as the gt35 but can hold up to 700 whp. im sure this is plenty for you if your looking for big numbers. personally i believe its wayy too big.
This turbo is a gt30 with the ability to withstand 400ish hp with great spooling capabilities. I would think this set up would be your best bet due to the less availability to fully build up our motors. Being able to piece together a kit with this great unit to me sounds like a dream for driving anywhere, anytime.

About the twin turbo set up, anything is possible, but you should look into pros/cons of a twin turbo set up on our vehicles. Price, Driveability, and ability to be used for long terms are key factors.

 

The GT35 is fine. Its proven to provide full boost by 3k RPM and make upwards of 400 WHP on a 6 Speed CL-S. And a unit capable of providing 700WHP is worthless. You're never going to lay down those numbers on a stock motor. And the Gt35R is rated up to 600 which is more than enough.

And like Blk2001tls mentioned, theres almost no room for a twin turbo set-up.

 

There is no sense in putting a huge turbo on a FWD car. Traction is an issue when the car is stock so even if you were to some how manage to acheive something higher than 400whp what would you do with it? Spin the tires.......

Stick with the GT35R or go with the supercharger

 

The guy who did the sizing of the turbo also works for Garrett, so he probably knew the best setup for the car.

 

Yeah I was just trying to think up different combinations that would be cheaper than the GT35R that would be as about as good. You get what you pay for though I realize now. Hats off to everyone we did all the research and work on the turbo project. When is someone going to make some more internal build up parts like some valves and springs. I'm curious as to how far you can take a NA engine using custom internals. All I've heard about is the 3.5 conversion. Anything new with internal engine research out there?

 

You can get some custom rods by Crower made and custom pistons by JE. 02av6 got this done on a previous motor, and I think that prices are 900 on both sets or so. You could also get the block sleeved. Everything basically has to be custom made for the most part.

 

Why bother re-inventing the wheel?

 

Without cams anything beyond the 3.5L upgrade with '05 RL pistons is pointless IMO.

 

ok i think i have it, small turbo for quick low end, yes it would run out of breath at the top end, but your low end would be soooooo much better. im thinking a IHI vf-39 series turbo, easy to find, spool up is great down pipes could easily be made. just use your imigination.

 

So if you just want low end, why not just spend 600 on a nitrous kit which should also give you both. Also a cheaper turbo won't flow as good and wouldn't yield the same amount of power.

 

take the $5,ooo(+) and go put a down payment on a new car

 

FWIW: That's a really cheap turbo.

Again, no need to reinvent the wheel. The GT35R will not loose efficiency before red line and will reach full boost before 3,000 rpm. If you are building a turbo car the one area you don't want to be cheap is on the turbo.

 

i saw an add on this new turbo from greddy i think FO47 sounded interesting

 

Some comments here... you don't generally want your low-end to be 'soooo' much better. As it is a high-compression 3.2L engine has sufficient low-end. My turbocharged engine makes PLENTY of power down low (300+ ft. lbs. at 3kRPM). You don't want your car to perform like a Saab and spin the tires off the line but then have NOTHING above 5k+. Believe me that is MUCH worse. Spool up is perfectly adequate with the GT35R. Besides with a smaller turbo, not only will it completely run out of 'breath', you risk overspeeding it and blowing it up. I don't know if you saw the comparision but allmotor_2000 used to have a smaller turbo. The larger GT35R made 70whp more at the SAME BOOST LEVEL and still had awesome response.

 

i agree with you here, i really didnt think about that aspect till you brought it up. problem is i have 3 turbos sitting here at home #1 ihi vf22 #2 ihi vf39 #3 hks t51r kai the hks is probably the best turbo to put in the car but its sooooo freaking massive i really dont think i will be able to fit it properly into the engine compartment. im really trying to keep the amount of components in the engine compartment to a bare minimum. i contacted allmotor, and offered lunch so i could pick his brain and listen to his experiences with turbo charging. he's 20 min away so why not. i just ordered the greddy emanage from excelerate because i know im going to need it.
