as title states, currently planning a turbo v8 build in my s13 and dont know whether Im going to run single or twins on my build... looking for some creative inspiration to kick start my plans.

post em up (please)

Thanks

 

what size motor? stock chassis build or tube chassis?

 

vh45de, 4.5 liter v8
might tube the front end, not sure yet.

 

drag car? drift car? power goals? built engine or stocker/crate? what trans? there is alot to equate into what you should do based on what your intentions are. throwing a V8 in a stock chassis S13 is already pushing the limits of the strength it is capable of, so throwing some FI into the mix is just asking for some insane frame flex

based on your sig and emoticon, i am assuming drift. a stocker/crate would probably be best. your not going to need anything large when it comes to turbo(s). in my eyes, you have two options. find some long tube headers. for option 1, reverse the headers, IE install them on the opposite side of where they are intended (flanges will be facing forward) and then fab some pipes off of that to put your turbo's in the location behind the bumper as needed. or option 2, install the headers as originally intended, and build straight pipes going to the rear, and have remote installed turbo's. your going to want something small and not laggy, with a pretty small A/R so your boost comes on instantly so you can break traction at any time

 

Did these for a 06' TT C6 corvette. They were the biggest pain in the *** ever.

 

holy **** ^^^^^

 

Toyota 1UZ TT








Camaro LS3

 

Very nice, I'm sure you were pulling your hair out quite a few times.

 

This particular chassis is a street car... its going to.be a stock stroke built vh45de. We don't have problems with flex at all. Car will just spin before enough torque gets to the ground. Power goals are 600-800rwhp on 91 and 70/30 meth injection. Still debating between twin 3076s or a single 4508. Trans is going to.be either a dogbox t5 or dogbox t56 with a mastershift sequential shifter. All other aspects of the car and DriveLine will he built... Ford 8.8 IRS rear end, etc.

Just looking at different design options for Turbo placement and such. And looking at the engine bay of our c6 z06 there's no way I'd ever attempt to place turbos under the Hood.. a lot of companies put the in the fenders on c6s.

 

here is mine that i built.

 

Wholy exhaust wrap!
Setup looks pretty good though! Tight space you're working with.

 

I agree.... tight space indeed. I'd be interested in seeing the backpressure difference between banks. Guess equal length is not a concern or even an option. lol

 

damn...everyone uses pipe. we have did a lot of rwd v6/straight 6/v8 turbo setups, single and twin and always use tubing and have never had a problem.

 

thanks it was a big pain to even figure out where anything should go. engine bay still cooks even with all that wrap. thanks for the props

lol yeah no idea on the back pressure. and not really any option for equal length on a single turbo v8 unless you relocate the radiator to the back. thanks again guys.
here is my build thread if anyone wants more pics and stuff.

^who's mounts did you use, that motor sits pretty far foward compared to other vh45de swaps i've seen...

the advantage i have is that i dont have a brake booster or clutch master, so the motor can sit basically as close to the firewall as possible... and as i'm not using a standard shifter, where the transmission sits isnt an issue as well.

i was debating on using 16g for the manifold... but i would build a triangulated heim joint brace whether i went single or twins.

i was thinking about doing something simliar to you if i went single, but i would place the turbo on the drivers side to make the downpipe easy, since i will be so low the exhaust will have to sit up in the tunnel... I'll more than likely have to extend the tunnel into the car

 

I always use pipe for thickness, radius and price. tube is harder to get in the thicker wall, more expensive and usually doesn't offer a tight enough radius. I've had plenty of thin wall stuff crack in the past. i only use thin wall on turbo back, cross over pipes or dump tubes.

Heres a set i did for a TTSC400 a few years ago which i used 12ga Tube on.

 

Bad *** manifolds. Top notch!

 

I really should buy you a beer for your patience. I worked on a buddies sc400, water pump, timing belt, etc. I felt like rolling the car out of the shop, dousing it in diesel fuel and watching it burn lol.

Manifolds look nice, I'm assuming you ran the downpipes along either side of the motor?

 

we have never had any problems with tube manifolds crack.

 

If you're ever in Tampa bay area, i'll take you up on that beer, haha.

They weren't that bad, i thought they were at the time, but Corvette C6 takes the cake. C is by far the biggest nightmare ever. I've been building some E46 stuff lately and that stuff is pretty hard too. More about trying not welding my self in a corner these days. its always that last runner on a tight collector thats a pain in the ***. nothing like having to cut a manifold apart because you can't reach 1/4" of pipe to weld. my next V8 setup will be my truck. I'm running a S480 on my 2001 Silverado 5.3L. Plan on 4 to 1's with a crosover and 2" dual up pipe to a 1.25 a/r divided T4. Trying to get some time to do it is the hard part. Probably won't have anything for a few months.

biggest problem with that SC400 was the DP route back. only enough room to run a single 3" back. under the turbos they merge into a single 3". The customer was ok with it at the time, so didn't really put any more time into trying to go bigger. I'm sure if i had another pass at it right now, i'd figure something out, but oh well. Live and learn.

 

That's pretty cool. Glad you've had success.

I've had pipe and tube crack, so maybe its just me lol. Not very often, but its happened.

To be honest, i don't mind the thicker pipe. takes a little longer to fab and there are more pieces, but i don't have to worry as much about heat soaking the piece while welding. little more forgiving.

Also if you run out of material mid build, most times you can find weld els and or pipe locally at a industrial plumbing supplier (ferguson, HD supply, etc...) so it makes life a little easier.

 

heres a top view of the fitment. similar to the TTI kit, except we didn't notch the frame. plus got away with no return pump. put the turbos high enough to run gravity without an issue. the kit was build around borg warner S200 .76 a/r divided turbine housing with the 4" antisurge housing.

on the 6.0L those twin spool instant. looks like you're looking at garretts. figured i'd mention the spool cause the s200's have a 65mm exducer which is pretty big. i'd probably be looking at a single if you intend on drifting. only one turbo to break.

 

I'm only looking at garrett's because in the end I'm going to have TheShodan build me something aroung my goals and he tends to use Garrett based parts so that way me and him can kind of get a baseline of what I need

 

my GF lives in tampa, I'll be down there soon lol... maybe i'll just tow the damn car too so you can build the manifolds haha

 

beer = good, twin turbo manifolds = bad, lol.

j/k, i do this stuff on the side, so it would be weeks if not months. i'm probably not your guy. more then happy to help if i can.
