Is it possible?

 

Sure it's possible. But what's the point?

 

It's not for me. Some guy wants me to get a twin setup for his 2001 Lude. What do you mean what's the point?

 

Well where would I get a turbo for a Prelude that is the right size for what you say?

 

"Build a Car: Email me with budget, base car, 1/4 mile hopes, desired mods, and we'll take care of everything."

This is not how I pictured a business owner getting the information he needed.

Look, tell me what the guy wants and I'll tell you how he can get it, and if he can get it.

Does he want performance? Drag racing? Street racing? SCCA? Top speed? 11's? 10's? Looks? Just has money to waste? What?

 

This isn't usually how I do my business, but this guy just asked if it can be done and I didn't think it was possible. This person is just a friend of a friend who wanted to know. He isn't a client of mine. I didn't ask him about anything like that so I wouldn't know. All I asked was is it possible.

Custom axhaust manifold, sequential turbos, and voila. Cheaper, smarter, less hassle route=correctly sized variable geometry turbo.

 

i'm not an FI crazy guy...and i sure don't know too much about it either

but please...explain to me how would u intall 2 turbos on a car with 1 header ??

and what would be the point ?

i can easily picture a twin turbo on a nissan 6cyl with 2 header and a separate intake ..
but on a lude ? or any honda ? ehhe

 

then you'd have troubles imagining the single turbo setup on a 300 or a Supra or an FD3.

Yes, it can be done. No, it won't be cheap, yes it's all going to be custom.

 

u will have a lot of clearance issues going twin turbo...it is already tight with a single turbo

 

If you did get a twin turbo set up. Being sequential would be an utter nightmare. Going parallel would be the only sensible route. It could be done; yes, but like said above just spend the money and get a properly sized turbo+ ball bearing and you would be much happier.

 

Twin turbo'ing an inline 4 is stupid.

my $0.02

 

if you wanna TT a Honda get yourself a sequential T2 setup

<--- BlueShadow

 

hey guys..just answer that please..i wanna understand there..

WHAT IS THE POINT ? of twin turbo on a honda? 4cy in line?

what would it give more than a single turbo stup and why ?
please

eheh

 

well one reason a lot of other cars like the Supra TT, 300ZX TT, RX7 (FD), Skyline GTR (TT) all come with twins stock is cause it offers better response. twins kinda become a neccessity too for engines above 3.0L , with some exceptions (Skyline GTR, RX7 [FD]). One of the reasons a lot of those people upgrade to a BIG single turbo is cause its simpler (less moving parts), and gives you more power. There are people however that are putting BIGGER TWINS rather than a BIG single.

Now as for TT'ing a Honda I-4. some of the reasons have already been stated above. beside the fact that it would cost a lot of money there is very little room in the engine bay. That and most Hondas dont even flow enough air to turn a twin turbo setup.

About the only Honda's worth putting a TT setup on, that would have to be the NSX, and maybe the Accord V6 and Acura CL if you can make them fit. I wonder if ther is enough room in the engine bay of an S2000 for a TT setup. I just did some calculations and the S2K flows quites a bit of air (327 CFM) at 8000 RPM's.

Maximum Boost by Corky Bell states that "sometimes" an engine with flow capabilities greater than 300 CFM can benifit from 2 turbos. Say someone with an S2000 go and see if there is enough room for a twin turbo in there.

Look at APex-I integra drag car, it's a twin turbo reversed engine

 

reversed engine ?
explain please


well then we could all use a twin turboed CRX with an NSX engine in the back
eheh
for street show off on lights
ahah

 

Its possible, but get ready for you motor to blow alot sooner....

 

Are you talkin about the white one? If you are then you should know that it is a totally custom block. Nothin honda about it. Cut from a solid piece of alluminum.

 

-not it's not the white one making 4,000 hp
it's a h22, on turbo or sport compact car
-reversed the intake manifold faces the front of the car, the headers face the firewall

 

notice the way the engine tilts forward http://www.evotuners.com/images/tarzan/DCP03208.jpg

the end, for now http://www.evotuners.com/apexiteg.htm

 

Ummm...whoever wants to know about a twin turbo setup on an I-4 has obviously no comprehension of turbo dynamics and function. First of all, like everyone's already stated many many times before, it'll lag like a b!tch. Even with two small ball bearing turbos. There just isn't enough exhaust flow to spool two turbos from 4 cylinders. You're going to need a hefty shot of nitrous oxide to even get them spooled. By then, you'll have a strictly drag car.

I remember this one guy who built a twin turbo DSM. He used two VERY small t-25 turbos, with custom manifold/IC/piping/etc. I believe it still lagged up to 4k+ rpms though. Hmm, I wonder what ever happened to him?...

No offense to the friend of your friend, or to yourself, but I think it's just an un-educated assumption that since one turbo is fast, TWO will be even faster! Knowledge is probably one of the best tuning tools.

*If has cash to spend, and wants to be "different" from the rest, then more power to him.*

 

There is one *possible* exception to that rule. My comment about TT's on an S2000 was semi serious. I was thinking that maybe a Sequential setup like that found on the 3G RX7 (FD) might work on an S2K. I only did some quick calculations for the airflow on an S2K at 8300 RPM's, and I came up with 320ish CFM. For 4000 though I came up with roughly 125 CFM. Figuring out CFM for a Rotary is something that I have yet to attempt.

Maybe a Parellel Turbo system might not work but I wonder if a Sequential system might work. That's if you can even fit a sequential setup in an S2K.

 

Thanks for the info, it's always appreciated.
