can't decide between 3076r or 35r...

[Fuzz_Duster]

I'm starting my BAT build, and just purchased some scat rods and mounts, and will soon be picking up my 1.8t AEB (w/ tt225 shortblock) to start building on.

I had my mind set on going GT35R, but now I'm wondering if its going to be too much in terms of being a DD car, along with the cost of the build. I know 3076r isn't going to be much cheaper, but it will save some money, and is supposedly a more streetable turbo.... What do you guys think?

things to consider: This is my only car, so its a DD. It sees anywhere from 600 - 1000 miles a month.
I'm kind of on a tight budget right now, and will be starting college within the next year.
This car will probably never see a track or drag strip, so it is basically a street oriented vehicle.
I'm looking for the most AWHP for the least amount of time,parts and money.

thanks in advance

[Don Supreme]

Based on the criteria specific the gt3076 is the better choice, no doubt about it.

[Nebone]

When does full boost come in on a 35R? I'd assume the 1.8T would feel mostly N/A driving around town with that turbo.

Get a K04......lol

Im no BT or BAT expert but I do but I do know if you go cheap and spend as little time as possible on it that you will have many problems along the way and down the road.

Take your time and don't do it if money is tight but thats just my .02 cents.

[Fuzz_Duster]

yeah, I think typical 35R spool is around 4500 RPMS. I drive a lot of highway though too, not just city.

My sensible side is saying 3076R, but then I don;t want to eventually say "damn, I wish I would have gone bigger..."

[AudiA4_20T]

dude ure still in high school and you have enough for a 35R? you pushing? lol I know I couldnt get 6k all of the sudden in high school

[Don Supreme]

If you get the 35r without all the uber expensive supporting mods then its going to run like a turd............... I run a 35r, so I am speaking from experience.

I would go with a 3076 based on the things you said in your first post, but if you don't have enough money to do it right, then I would just wait until you get the money right.

yeah I don't mean cheap like skimping on parts, i mean cheap as in total build cost.

I graduated a year early, so I've been working full time as a framer since last year. $14 an hour, with only a couple bills to pay adds up over some time man . So yeah, I'm a 17 year old kid, who's planning on going BT.

badass man, that would be real nice but I did enjoy senior year. Anyway good luck, shoot me a PM and we can go over this stuff, but shit is going to be EXPENSIVE. Its always more than u think. Id estimate about 6-7k for the setup

if your going to go 35R, id run the setup Chris Tapp ran and just get a file from him

[goody6691]

building for either setup is gonna cost close to the same. rods, pistons,headwork[so you can spin it up higher to make use of the bigger powerband],headstuds,bearings and the build cost. building a motor is building a motor. you could just throw a 28rs on the stock motor, make 300 whp and be done. a built, big turbo car is not the best daily driver.

[pipe7284]

stay with the your stock block and just upgrade rods and replace piston rings. and then slap on a gt3076r. and your good to go.

yeah, it does make more sense.

I'm kinda at a point where its all or nothing right now just to get the build over with so i can fully focus on college. I've read too many stories on here where its taken the person over a year to finish the build because they're in college and funds are limited

I think I'll go 3076R and be happy. I just really wanted to be able to make all the big-headed ritzy z06/m3 owners shit a brick when a little red audi is pulling right next to them while they're floored

[Don Supreme]

Well you will be able to do that to a m3 with the 3076, but unlikely with the current z06.

[Poopie]

if you crave a bit more top end you could always try a .82 ar turbine housing. Thats what i went with. It spooled pretty nice in a b18 honda I got to ride in.

I will have a head built for higher revs though. my redline will be 8100.

[Fuzz_Duster]

I know, thats the sad part. I live in one of the United States largest retirement cities, so almost half my town owns a new corvette, and they just love to show them off by trying to race every person possible and flaunting them on their meets. I'd just love to see the look on one of their faces if they got beat by a '98 audi. I guess I'll leave that to people like mike hood and chris tapp!

Thanks for all the help guys!

(Don_Supreme and A4_20T I will probably keep in touch throughout the build.)

[goody6691]

a 17 year old kid with a 3076 a4 is bad news. your already talking about racing vettes. use your head when you drive. that thing will get you into big trouble, esp if you dont respect the power. not trying to bash you, i just get sick of heaaring about you ng kids getting fucked up or hurting inocent people in accidents.

That sounds aweful familiar

[A4Rob]

In all honesty, since your on such a tight budget, just buy a PES T28. I ran my T28 kit all through college and it worked great. I am selling mine now however...

3076 or 35R will end up costing you a lot of money. I can tell you that because I am working on a 3071 build now.

no way man, I'm a god driver. I've only been in one accident, which was NOT my fault, and have never been pulled over. I do the speed limit, there's just times when I like to wind the car up for a minute, like when I'm on long trips on the highway. Other than that I just have fun getting up to the speed limit

[Fuzz_Duster]

yep, its good honest hard work, and it has certainly done a lot for my body as far as getting into shape . Though there's a lot of time I catch myself thinking "how the hell did I get here...". Like when I'm rolling trusses 3 stories up in the air on a roof in the 95 degree + weather with a bunch of middle aged guys who look like they belong in a bar or in jail..haha

Keep in mind the guy telling you this has a full 3076 setup

Oh Im a mechanic... I was referring to the fact that I finished my senior year in college, and now have my associates degree in automotive at the age of 18... Ill be 19 next week and have been working my ass off for a while to get the car to where its at now

[Fuzz_Duster]

oh yeah, right on. I was raised strongly in working hard to achieve something, so I can respect that for sure. The sad part is I've just started buying these parts (as you know) and I'm already anxious to be able to feel what its like to own a car with over 400 hp

Uhh, how the f are you not 19 yet and just finished your senior year in college? That doest begin to make sense.. Unless you meant u just got done with senior year in highschool..

[bassed]

3076 .82 a/r or a S256 w/ .55 I know it's not on your l ist, but it should be. It's in between here is a little info for you

[goody6691]

i just got my .82 t3 hotside in the mail the other day. its going on this week, along with the spa mani, injectors, and uni goodness.

Ya i think the same thing when im at work. Makes me think i should have just went to college right after high school and didnt get into the construction biz. Atleast if feels like ive learned a bunch and can work hard to take pride in my work. Then i get home and read over all these bat builds and cant wait until i have the courage/funds to do mine.

[djwimbo]

If you're looking to make 400 maybe a little more, I'd go 3076 w/ .82 A/R. The 35R can hit those numbers without issues. The concern is that once you step up that high most people would recommend the more expensive parts, so you'll benefit the most from the larger turbo.
Honestly I wouldn't consider stepping into the 35R range unless I planned on doing oversized exh. valves and a ported head.

SPA Mani + 3076 will probably get you a lot more than you'd expect. If you ever get to the point that a fully tweaked 3076 isn't keeping you happy, you should probably go buy a Viper and turbo that. 300whp is plenty enough to get the best of us in trouble, 400whp is another story.

The roommate's Vette was pushing somewhere in the neighborhood of 425whp and 400wTQ. It was enough to pull any 600cc street bike by a couple car lengths before 3rd gear ended.

[Fuzz_Duster]

where the hell do you buy a borg warner turbo at anyways?

[djwimbo]

Oh yea, are you planning on going 1.9L, 2.0, or 2.1?

yeah, i know I'll be happy with the 3076. Just looking at it on dyno sheets, and driving it I know are two totally different things. I'm sure I will probably be 100% satisfied with whatever numbers I make, because at least its more than my stock k03 is pushing right now!

[Fuzz_Duster]

83mm bore with a 92.8m stroke, which I'm sure is 2.0L

I hear you there!

[djwimbo]

Correct, That'll put you in the neighborhood of 2007-2008cc if I'm not mistaken. So, an honest 2.0L, w/o rounding up.

[Don Supreme]

Who is building that motor for you? Unless you have a shop that has done it (stroked 058a block takes a little doing) before there is probably going to be some back and fourth (major project delay). If you have the money you could order one from Bob Q...... He is expensive, but you know its being done right the first time....

When you see his prices you will see how we came up with 6k-7k.

[djwimbo]

What makes the 058 so hard to stroke? Would it just be easier to do a 06A block for us AEB guys?

[317ssayzarc]

Uhh, how the f are you not 19 yet and just finished your senior year in college? That doest begin to make sense.. Unless you meant u just got done with senior year in highschool..

Well my birthday is in late August, I started my freshman year of hs when I was 13 (just for a few days) since I was just on the brink of being held back but my mother put me forward anyways... Went up thru hs until the end of my junior year, then started talking to colleges about how to start my degree and finish up the remainder of my hs courses in college... I took a health schedule each quarter in college (while still working full time mind you) and finished my associates in 18 months... Make some sense now?

Read my write up in the FAQ

[Fuzz_Duster]

I've actually had a couple people tell me I don't even have to stroke out my engine, and that I could keep my AEB totally stock, run new scat rods, large injectors, new oil/coolant lines, manifold, full exhaust with downpipe, AFPR, inline fuel, 3076R turbo, 43mm external waste gate, dump pipe, large MAF, and some new plugs and be good... but of course it wouldn;t run close to its peak performance...
