I searched and didn't see anything like this..

We are building 3 vitara hatches this season. We plan on actually finding the limits of these setups and were wanting ideas.

Are's go something like this and they belong to three separate people in the same shop.

93 hatch
30r FJT rods ram horn 50mm bov - Almost completed

92 si hatch
57 trim - the rest is up in the air with this one and am willing to try almost anything

CRX
57 trim eagle rods air to water, this one has been running for over 10k miles.

All of them are running ectune pro bundles, 38mm gates and 75mm std bore Vitara pistons.

We have so many d16's and d15's at our shop we needed something fun to do with all the parts, so in came the **** box hatches.

We will update this post accordingly.

 

We will find the limits to atleast 1 out of 3 things on my build.

-Vitaras
-Stock Sleeves
-30r capabilities on a d16. LOL(i think it will be one of the above)

Mine is the 93 hatch mentioned in the first post. I will post some pics later this evening or tomorrow of some of our progress.

 

Sounds like you guys are gonna have a lot of good cheap fun!

You are probably going to need to run bigger turbochargers and more boost to find the limits of the vitaras, though. I ran 471whp/356tq @ 29-30psi on them w/stock sleeves and they held just fine. The 30R build might possibly be able to surpass that if it's cranked all out.

My motor finally had a piston failure on one cylinder at the last race of last season, but it was not because we had reached the limits of the pistons strength - it was due to abnormal combustion in that particular cylinder only.

As far as the stock sleeves limits, I had not reached that yet either. When the vitara piston was damaged we rebuilt the motor in the pits overnight, but with a used set of partially damaged 9.0:1 SRP pistons (that was our only available option at the time). The setup had never been tuned for that compression ratio, and we got it back together and running just in time for the 1st round of eliminations. So we just pulled a couple of degrees out of the timing maps and went for it.

Well, it wasn't enough, and the motor experienced EXTREME detonation the entire pass. It finally cracked a sleeve on cyl#1 at the top of 4th gear, and went 10.6 @ 134ish mph on its last pass.

After getting it back to the pits and examining the plugs (they were completely coated in aluminum), it had endured the worst detonation I have ever seen, and still managed to hold for nearly the entire pass. This tells me that the sleeves would've held up to a lot more power than they had been seeing if it wasn't for the extreme detonation that occured.

We are currently building another stock sleeve vitara motor for this year with some major changes, in an attempt to find the actual limits of strength of either the sleeves or the pistons under normal combustion events.

 

I have been referencing your car quite a bit lately. I feel like I should be able to surpass your 471whp. Looking to run in the neighborhood of 30psi on the 30r. Also my car has a little higher compression than yours. But who knows. Your next build is probably a 35r build with some badass head work. But I like the competition and maybe we can get some more high hp vitara setups going. Im just looking for a solid 10 sec car and i will have roughly 3200.00 in it when it is complete. I have had quite a few parts along the way and the guys at Modern Muscle have helped me a great deal with the building of the motor and have spare parts laying around. Wouldnt be possible without you guys.

****Progress on my build...Put the head on last night and torqued everything, put the rocker assy and cam back in, and did some work to the motor mounts. I have been meaning to take a camera with me to the shop but i keep forgetting. I will try and snap some pics friday.

 

Im hoping mine will be in the 400's.
Havent gotten to the dyno yet though.

 

Thanks for the props man.

I really do enjoy these setups and it blows me away how they can go so fast with so little money involved. Its funny that you could build a 10sec capable vitara hatch for less than the cost of my top mount b series turbo kit.

Honestly if it comes down to it, well port what we can in my head, nice cam, springs/retainers, install my GT3082/3065R, a little q16/c16 [maybe import? ], 30+psi and were bound to find some limitation or produce some really good numbers. As long as it doesn't take the turbo out when it grenades I'm happy..

My biggest problem or what I'm sketchy about is the d series tranny's... Are they really going to hold up? I fell like we need to budget for multiple tranny's a season, and maybe a nice gearset.

Hey JFK, you wouldn't happen to shed some light on what kind of timing you are running at say 30psi, 9k rpm's? I'm trying to get a ballpark idea and if you didn't want to share on the forums I would completely understand.

Thanks for your time

I was wondering what was going on with your setup. I havent seen you much on turbod or d series. Hope to see some good numbers from all these setups. I am shootin for 400 or more myself. Just have to save up money for my next tune for hi boost. Good luck fellas.

 

The 30R is a great turbo, and should definitely make more power than my 57trim did. There were many less than ideal parts on my last build, and areas where power can be gained through different parts choice. That setup was never built to do what it did, I just kept pushing it and it did quite well.
Friendly competition is always a good thing!
I would love to see others push the vitaras as far and beyond what I did last year. I love 10 second single cams, incredible bang for the buck. They are so cheap, yet people are still afraid to push 'em. What better setup to build and have blow up than a vitara build?

My next build is something like that, but with plenty of "low budget" thrown into the mix, and a few minor "tricks" I've been wanting to implement. I still want to keep these builds as cheap as possible.

I'm looking forward to seeing the results of your build!

Working 60 hrs a week at the shop doesn't leave much time for the internet, or anything else for that matter! Good luck on the high boost tune!

 

^ I feel you on that. I put in 60+ a week myself working full time and part time. Its hard squezing everything in in a 24 hr day lol. Cant wait to see your new set up and thanks.

 

my short block is put together. my car is a purple ek cx hatch. I am using eagle rods with .020 vitaras. the block is an a6. the head is zc going to be P&P, skunk 2 vavle springs, with jge titanium vavles and retainers, zex 59300 camshaft, true time cam gear.

havent decided what IM to use yet. I am a college student and my funds for this build are running real low. I have a z6 IM, TT 680cc injectors. I should probably get an h22 TB for it or atleast a b-series TB. the exhaust manifold is pfabrications log, tial 38mm........ the turbo is going to be a holset hy35. it is supposed to flow at 60 lbs/min so i hear. the exhaust will be 3in piping all the way back with it being gutted.

my tuner sewell94 is going to be tuning with ectune. we are shooting for 400whp. this is my DD so the tune is more than likely going to be a bit more conservative.

 

^^im interested in seeing how that holset works out. They are becoming a popular options.

I took pics last night and will post them up here in a few.

 

ok here are a few shots of the build.

Chassis 1993vx hatch.


Motor on stand. d16z6, 75mm vitaras, FJT I beams,Skunk2 IM, Spoolin Performance Ramhorn, Tial 38, GT3076r w/.82 exh housing(shown with 2.5'' outlet) I do have a ceramic coated 3'' outlet housing on the way.






Crower springs and retainers




Will probably be using an LS throttle body on this build. I recently ordered some intercooler piping and I have a purple tial bov to go on it. Thats about all the parts i have left to get before we can put it back together. That and we are waiting on the tranny. Im having another guy weld the diff up and when thats done we will be dropping the motor in and the car should run within a week or so. I will be using the stock cam for break in and after that i really dont know what i am going to buy. The zex or a bisi cam....idk.

I will post more pics later of another Modern Muscle Project car.

 

in for updates

 

I like that gold Valve cover. I have a video for you. http://www.youtube.com/watch?v=bZfyr...eature=related

that is a nice build though. i like it. wish i had your manifolds.

I will post up pics. i went through alot of turbos before i decided which turbo i want. hx40w, hx35wg, and now hy35...... it is suppose to be very similar to a gt3076r. i wish i had one to dyno both of them and see how they are alike.

 

Thanks man. I am looking for around 500hp on my setup. I would say we will tune it to around 450 or so and track it and then slowly work our way up.

Here is a pic of my rear mount, what do you all think?



Here are some pics of another car in the shop.

 

A basic log manifold is definitely gonna hold back a lot of power on your set-up.

 

you guys are all doing a good job out there at the shop!

i'll try to swing by at some point this coming week and snag some more pictures to post up on here. can't wait to see all the projects running around here soon!

 

im never really on this site that much, spend most of my time on d-series.org... but so far my vitara set-up is holding up with 25psi on a 57trim garrett.. went 11.30's last season with a cast manifold, completely stock head, bone stock tranny (no lsd), and i was still cutting 1.61 60fts with 24.5" slicks, and the last run of the season is when my diff finally gave up... i made a little over 400hp last season... just recently i did alot of headwork.. porting, comp 59500 cam, and springs... bumping the boost up a little, taking the rpms up another 1000 rpms, lsd, cage, and a few other little goodies... after pulling the head off a few weeks ago, the cylinders and pistons still look like new.. no det. marks or anything.. so with this hardcore cam, and the other stuff im doing, im expecting alot more power with pretty much the same boost level... im using q16 fuel... hopefully i will be able to run somewhere around mid 10's... so far it shows no signs of letting up...

 

yea.... we will see what happens my tuner is the **** and he made 700whp+ with his rev hard cast iron log manifold on a fully built gsr.

 

im lucky.. mine is a cast manifold, but it not a log... pretty much a cast mini ram manifold...

 

i dont believe rev-hard made "log manifolds" really. just cause its cast , doesnt mean its a "log"

 

agreed. alot of people think all casts are logs..

 

Thanks man, stop by anytime.

Were hoping to get Phillipa's [oneoverwrx] car straitened out real soon. Its coming down to just the little odds and ends. I honestly can't wait to get past the break in and get a good race gas street tune on it. I'm sure we'll have one hell of a good time with that. It better go good, I caught him measuring up one of the dsm homo's 4g blocks asking silly questions about t-cases and what not.

See Phillip, I mean Phillipa he had to give us his buddies some fair competition and create a chit box, stepping down to our honduh level because we couldn't see past his parachute on his wrx and none of us have anything for that yellow rally rocket I wish he'd post up some pictures of it, its bound to be one of my fav local cars.

Jordo [yellow crx], hopefully he's loitering around ht reading this and decides to remove his testes out of his purse, slaps a new map on it and adds a little gain to that solenoid.

I just need to keep em outta the wall and finish something competitive before mid season. All I know is that I'm gunna cry like a queer if any of these one cam wonders ***** my b series build. At least there will be room for excuses if they beat my vitara build.

DK

 

here is a motor pic of the wrx. Dont really have a good pic of the car after it got out of the shop though. I will get some this time around.

 

I'm thinking the low compression is a big reason why we are able to push so much power on stock sleeves and without harming these pistons. I may be off on my theory but I think with the poor head flow at such high boost pressures and high RPMs a regular 9:1 piston is just going to be so det happy that we're going to have to pull a ton of timing and start losing power because of it.

It's either that or it's because you're only running 100 octane and the bump in compression threw you way over a reasonable octane det threshold.

For me this year will just be getting the car safe for the track (safety first gents, power is cheap) and getting the car over the 400 mark. Maybe the next year I will do a teardown with a new turbo, more headwork, and some backup engines for testing purposes lol.
