First off I would only like ppl that have lots of expeirience with both cars.
How much harder is it to road race/cayon carve a 250-300hp turbo vs. a 200hp N/A.
I would really like the little bit more striaght line performance that the turbo offers, but I am not sure on how much harder cornering is with lag and other such things.

Who has a 200hp N/A?

someone with a BP Mr. Rat, but I was rounding up would probably be more like 185 at the wheels (big street port side draft intake Microtech blah blah, silverGXL got 161 on stock ports and intake).

Ahh, well, I can tell you the difference between my 220 TII and my 160 NA, but I'm not sure if that's quite what you're looking for.

I can tell you that the turbo spool makes cornering a bit more of a challenge.

I think that I worded my first post wrong, what is it like with lag and such? (so s-rat I would like to hear from you). I am trying to decide if I want to keep it N/A or go turbo.
Could a small aftermarket turbo be built to keep lag/spool to a minimum, and give me the power that I want?
And J-rat I love the end of your sig

I quite honestly don't notice that much of a difference, however my TII driving has been limited as my poor car's been out of comission longer than it's been running. It takes a bit longer coming out of corners to get going, but hell if you can keep your rpm's up you don't have to worry all to much about that. The slowest part that I felt were like sharp 90 degree corners where you have to slow down almost to a stop and then take off again.

It really shouldnt if you corner properly...


I mean...theres a difference...but not that much of one.

Bah. If you keep your engine at above 3500 rpm, full boost is pretty much instant with the stock turbo. Get an open exhaust and that number will greatly improve.

If you're concerned with overpowering a corner, just don't press the gas as hard. And when you come out of the apex, mash it for the straight line until you hit another corner.

Damn you guys, now I think I am going to have to join the dark side later this year.

adamlewis

Yeah...boost is instant when you floor it, but thats not how you should drive when exiting a corner.

RETed

You basically gotta reaquaint yourself with the new power curve.&nbsp Your NA already has a flat torque curve, so you can do really stupid things and still get away with it; pump the throttle in the turn and still keep the car under control due to the even torque.&nbsp It's hard to do this with a turbo engine, since you have a peakier(?) torque curve which ramps the power out a lot more abruptly.&nbsp You try and pump the throttle in the corner with a turbo engine, and you'll end up with a scary ride in a hurry.

If you can learn the power delivery of the turbo engine quickly, you'd have very little time adapting it to some spirited throttle steering.

Yes, you can pick aftermarket turbos that can keep the torque curve as flat as possible, which will minimize the peakiness of most turbo engines.

Well, I was used to the N/A, so it was a bit of a chore getting used to the TII.

FCdemon

for canyons, you don't need 300HP, you need a built suspension and maybe 250HP with the least lag possible.

ponykiller

You will want a turbo that does not have very much lag, as lag is what will get you into trouble when you are throwing the car around corners. Hybrids are what work best for autocrossing when you still want lots of straight line power. Just remember that you cannot mash the throttle half way through a corner in a turbo, as the lag will make you think you are okay, then boost will hit and you WILL lose control.

It is all about control, and you just have to learn what the car does and what little quirks it has.

I'm a certified throttle masher, and it's gotten me into lots of trouble

jon88se

i dunno guys, a solid NA chassis (proper suspension mods, least springs/struts) completely out handles it's power...the car feels wrong unbalanced in that respect, it always has. TII swap the the rescue to even things out got a GReddy FMIC, streetported rebuild, FCON, Walbro and type S BOV so I expect 240 rwhp and a lot more fun. what I WONT be able to do anymore is CRANK into low speed corners in second gear and mash the throttle...w/ my lovely coilovers and bracing setup (still w/o a LSD, coming though) I just get a bit of throttle oversteer that is very easily correct for some fast and impressive lookin 90 degree turns. try that w/ the TII setup coming in and it's spin city unless you modulate the boost w/ your foot and what fun is that!!

How you planning on running a carb intake with a microtech?

With 50mm Webber style throttle bodies, DUH!!
Why does everyone here try to prove everyone else wrong?

Does anyone here have a suggestions on what turbo I should buy? I was thinking about the Garrett GT22 you can find the specs at http://www.turbobygarrett.com/turbob...jsp/index.jsp# (pg. 12) or I made a pic of it but can't upload it to my ISP right now.
Are should I just stick with one of the stock turbos?

casio

whats so surprising about 200? thats nothin. you dont even have to think about bridgeporting to get 200 to the wheels in an n/a. just a decent streetport.

Ni5mo180SX

Well coming from a NA to a T2 motor now I think theres a bit of a difference.

Its not that difficult to adapt to the turbos power curve, I found it more difficult to the rate of acceleration. You're going much faster in the T2 then the NA in a hurry so if you're not used to it, you may end up in a bad situation quickly. Also I think the added power stresses the stock FC's suspension in a broader range of situations but nothing a modded suspension and exp'd driver cant take on

j200pruf

Yeah the suspension thing is going to be taken care of this summer. I am going with KYB AGX's, GC coilovers, and Enkei RPF1 17x9's all the way around, maybe some strut bars and poly bushings.
But now one has an idea about what turbo to use?

88IntegraLS

. . . . exactly. Couple that with a 2400 pound car . . .

Comone 88, I figured I could lure you up here to help me with the turbo, you'll work for food and beer right? j/k
I know everyone says its easy to get 200hp at the wheels, just know one has got it yet, but witha street port Microtech and a DOCE manifold with 50mm TB's and I bet it would be there with tuning.
But I want to go with a turbo cuz down the road I want to have a car with more than just 200hp, and a turbo is what needs to be done to get that hp, don't feel bad I will be keeping a n/a for a daily driver. And just think of a 2400lbs car with 250 or 300hp.
