Best turbo for big HP dsm?

[VR4OOOM]

Ive got my mind made up already but just wanted to hear your opinions :)

What turbo would you buy (lets just assume money isnt an object) to make a lot of power on a 4g63 that will be a 70/30 street/track car and is fwd. Nitrous will not be used. Boost will prolly be around 19 on the street and 25+ at the track.

Discuss...

Oh, and also assume that the motor is built and that all the associative mods are in place :)

[Iwishiwascool]

This is definitely a Mike C question.

How about a FP 60 trim :D

[Iwishiwascool]

20g or BR500 would be the choice of myself and someone who lives so near me.

[v8etr]

I ran the 60-1 on my 90 Laser. I was pretty happy with it. No way you would run 19 psi on the street though. At least not on the pump gas we have down here. Mine knocked it's butt off above 15psi.

[dsm_obsession]

i really like the 20g and the 60-1 has showed its potential too.
you got to look at where you wanna dump the clutch at a too.
because the 20g and 60-1 spools up[ at different RPM's if im not mistaken.

[DQ Driver]

in no particular order

1) green 7cm housing - nice linear power, +15-20% flow to the 20g, relatively quick spool up, full boost @~3800 rpm in 5th gear

2) 20g with td06h turbine wheel - a little laggier than a clipped td05h turbine wheel to offer you a chance to get some traction with some lag, very peppy for the street and strip

3) br500 aka pte 50 trim - new hotness, full boost at ~3800, linear, great pump and race gas performer


#3 is the cheapest by far with an internal gate
#2 old skool nostalgia, kinda costly either way
#1 is still cool, has worked well internally gated, yet still pricy

[Mike C]

What are we considering high HP? This means 400 to some, 650 to others. Any idea what kind of numbers he wants run? Hard to give an answer without knowing this.

[jplong]

add a 7cm FP Red.....
but you will notice more power with race gas and higher RPM with thte red...so a green may be the ticket..

[BlackEclipse]

I think anything bigger than a Big16G needs to be ball bearing. Waiting forever for spoolup sucks on the street for daily driving. My turbo is right at that limit.

[ucsigep]

I would say 8cm Green, though. A friend in Dayton gets full boost by 3800 in the 8cm, not the 7cm.

[SmokinEAGLE]

i know you know that FWD power isnt the best for the street. is the idea to make big #s (why would you need to do that :cool ), or actually be fast light to light, highway, and at the track with the aid of slicks. I would go, and have been wanting to go with a tdo6 20g, i cant justify loosing all hope of traction just to break the 400whp barrier.

"High" means somewhere in the 450-500whp range :cool

Ive already had the td06 20g and want to go a bit larger on a dual ball-bearing set-up ;)

Looking at something along the lines of a GT35R but just curious what you guys would say :)

[Mike C]

I'd say that a GT35R would be a tad overkill to make 450 to 500whp. You can certainly achieve those numbers on a 50 trim setup with good tuning and race gas and a solid 400whp on pump gas. If $$$ was no object, I would look at the full Garrett setups from AGP. A stage 3 turbine wheel with a .63 A/R housing is going to give you full spool up around 3800RPM on a 8.5 to 1 compression motor no problem. I made 400whp on this setup on a stock 2g motor except for a set of cams at 22 PSI. Cheaper alternatives would be the previously mentioned BR500, PTE 50 trim, 8cm Green ETC. If this car is a 1g, with 2g pistons and a 1g head, the increased flow would make a big difference on power gains on the larger turbo. I think a 6 bolt with 2g pistons, and a stock 1g head(with maybe a set of cams) will make close to 500 whp at around 25-27 PSI on C16 fairly easily with ha 50 trim. There are plenty of other turbo choices that will get you this number easier on race gas but the daily driving and pump gas tuning will be more difficult. Just depends on what's most important. The 50 trim varieties can not be beaten in this compromise.

[DSM614]

So, your looking to get that poor lil' laser off them jackstands? haha.

I was thinking the 3rd MIKE choice... aka... 3) br500 aka pte 50 trim - new hotness, full boost at ~3800, linear, great pump and race gas performer.

I think mike and mike have great minds, and they think alike. :p


One of these days, the bully will have a lil power... :thumb

Lol. I read this and thought 'Doesn't he allready have a 20G? Is that not big enough? He must be shooting for some high numbers.' :eek

[VR4OOOM]

I'd say that a GT35R would be a tad overkill to make 450 to 500whp.

Im all about the "overkill" :p I just didnt want to say "500+whp" and sound like it needed to be a dedicated track car or something. I want 450whp on the VERY conservative side.

The laser is more than likely being put to sleep. This set-up will be on a GST.

The 20G i had on the laser is now happily on my bros talon--it should do well with a little shot of the giggle gas and 20+ psi :thumb

[Mike C]

IMO, anything beyond a 50 trim sized turbo is a serious committment (built motor, built tranny, and especially engine management). It just depends on how far you want to take it with the supporting a mods. A 56 trim compressor wheel (GT35R, SC61, FP3065) type turbo isn't going to be easy to tune with a piggyback system. Also, its more of a committment to a race gas setup since none of these turbos are going to be great(can of worms now opened :) ) on pumpgas.

Mike, what are your thoughts about these turbos on a piggy-back system like the E-Manage? Obviously, very few of us have experience with them, but do you think it would be any easier to do than with an AFC, VPC, etc. etc.? Your thoughts, along with anyone elses...

[Shearer]

Big power? Slap the t4 kit I'm working on on that slut with a t88 or 72mm turbo. Yum.

Cool, did not know that. Sorry to hear about the laser giving up the ghost. Can't remember, what'd you bro's car have on it before, big16G?

Don't you have another fast car to worry about getting running before you even think about this one. :p At any rate, sounds like you have a wicked little car planed. :thumb

Yeah, he had the big 16g that was on the laser when i bought it. Car ran really well with it--enough to whoop a certain C5 that runs 12.20s twice in a row from a dig :cool

My other "fast" car is sitting in the garage awaiting spring. All im doing is getting it aligned and putting in a new cd player and shes all ready to roll :beer

Gonna be a fun year :thumb

I have 0 experience with the Emanage. In concept it seems like it would/will work great. Being able to achieve the right A/F ratio while still having control of the car's timing should work great. The problem with it is nobody's running it so there's not alot of support for it yet. If I had a 2g, I probably wouldn't try to pioneer it and would just get DSMlink. On a 1g, its alot more appealing as an alternative to a standalone. Isn't someone in that house going to try to pioneer the E-manage? :D

Would that be a certian red sprayed auto C5? ;)

It does sound like it should be a fun year. :beer

[V8hunter]

hey jeff, i think u should stick w/ your orginal plan -- the turbo we discussed is more than capable for the big numbers u want

[VR4OOOM]

:thumb

And as for the questions about the Emanage/E01 it is a set-up im contemplating trying out just to see how effective it might be. Weve tuned this setup on a couple different turbo hondas but not on a dsm as of yet.

Its obviously not going to be as effective or as precise as using a full stand-alone such as the AEM but the gst is going to be much more of a budget car and daily driver than the vr4 so cost is winning out :(

Im gonna do more research on the various set-ups before i make up my mind on which i want to go with but its one of the options for sure.

[Mike C]

If its going to be more of a "budget" car, then I would steer clear of anything bigger than a 50 trim. Otherwise, you better have a good stash of $$$ for repairs :D

[VR4OOOM]

What will i be repairing just outta curiousity?

Possibility is always there for the tranny and half-shafts but i doubt if the car will ever see slicks. More power just = more spin :p

[Mike C]

What year car is this ? 1g or 2g? My assumption is that when you say "budget" you mean that it is on a stock motor? If so, then you will obviously have motor problems trying to spin a 56 trim type turbo up to the PSI range where it is efficient (26-36PSI). That's where my repair $$$ suggestion and the smaller turbo idea came from :) It would be helpful to know what supporting mods you are planning to do to the car and it would make the turbo choice easier.

The car is a 97 gst

Fully built (forged internals) 6-bolt :cool

[Mike C]

"budget car" huh :D Boost away then. Seriously, as long as you are committed to occassional tranny/axel repairs, then it could be minimal. It will lastly come down to engine management and deciding what will work best. Is it a 2g where DSMlink is a viable option?

Ah post edited :) Since its a 2g then I would goive DSMlink a serious look.
