The new improved Turrari 5sfe

mrturrari · 08-30-2006, 01:49 AM

I just finished my engine rebuild this last weekend and thought I would share what I have been doing for the last 3 months. Back in May when I had the t3/t4 50 trim on the car it was running great but somewhere along the line I over boosted or ran it lean. I didn't see it happen or know exactly when it happened, there was no boom or sudden loss of power, and the wideband read safe mixtures while I was watching it for over two weeks of boosting. It started to consume oil and when I would boost it would suck oil into the catch can and then start dumping it back through the turbo. Finally after pulling the head I discovered the problem. The ring lands on pistons 2 and 3 had been cracked by the force of detonation and that was allowing blowby to pressurize the crankcase. So it was time for some upgrades and to return the car to NA for while to get everything sorted out.

The new improved Turrari 5sfe has the following mods:

Atomic Speedware custom 9:1 forged pistons 0.030" over
Total Seal nitride rings
Eagle H-Beam 3sgte rods
Clevite 77 bearings
ARP head and main studs
Fidanza flywheel
Spec Stage 3 clutch
NST underdrive pulley
Ishihara-Johnson crank scraper
98 5sfe oil pump w/ relief valve shimmed 1.25mm
Rotating assembly balanced front to back
HKS 2jzgte adjustable cam gear
2mm oversized ferrea SS valves with head and porting to match
2jzgte valve springs
ATS Racing 170 degree thermostat
Custom home made 4-1 header
ATS Racing 2.75" Stainless B-Pipe
Stock turbo muffler

I really missed my 5sfe for the last few months and except for an exhaust leak it is running perfectly. I drove around for 5 hours breaking it in last night and loving every minute. The clutch is a little hard to get used to as it is a little grabby compared to stock. I also have to rev a little more from a stop because of the lightened internals. I am still chirping the tires on green lights even when I don't mean to.

Now you are probably going to ask how much power does it make with all those mods? The answer is probably about 15-20rwhp on the butt dyno more then stock. What you have to realize is that most of these mods are not in and of themselves going to make power but are going to be priceless once cams and an EMS are added to the mix. Time to start saving for those cams.

So jeff, are you going for the NA record?

How are you coming along with your MS? Did you get it together?

Just gotta say that is a very healthy list of mods for an NA. Do you plan on putting your turbo kit on it eventually when you get the cams and MS installed?

Edit: the crank scraper, I just got done reading about it on there site, in your opinion (obviously since your using it but...) do you think this modification is worth the price? How did you get it to match your crank so it doesn't scrape the crank. Will it hurt the crank if it does?

Mister2.2 · 08-30-2006, 02:18 AM

Sweet! I still have a set of ITBs laying around, Tom was supposed to take them but....well I still have them. Looks like you have a good build up so far, I can't wait to see the end results.

Yes... probably.

Mostly. I'm still figuring out the IAC circut and will need to filter the VR signal from the distributor.

Yes. This is a all purpose motor. That's why I went with 9:1 CR pistons. By the way I can't even tell the power difference with the lowered compression.

It was $65 shipped so for the price it is a very good mod. For those that don't know it keeps the crank from scooping up oil around corners and during acceleration reducing windage which creates drag on the crank. V8 guys claim gains of 10-20hp or more but with the stock windage tray on the 5sfe I don't see it gaining so much. The crank side of the scraper was precut to the right shape but I had to grind the block side to fit my 93 block and also modify one of the mounts because I have ARP main studs. It sits about 1mm from the crank and if it were to hit it would probably just bend or break. I'm not really worried about that though because the 5sfe scraper mounts using the main bolts. If those go you have bigger problems.

Yeah, i kinda have a problem with this statement.....do you believe it will cause damage if it does break? Could it plug one of your oil lines?

Great job on the project, i can't wait to hear what you do next with it. Any chance of a dyno run here pretty soon? I wouldn't mind seeing what you get with those mods.

mrturrari · 08-30-2006, 03:45 AM

lol Yeah I didn't know this stuff 6 months ago.

IAC = Idle Air Controller (I think) - it allows the ECU to set your idle speed.
VR = Variable Reluctor - the magnetic pickup in the distributor that tells the ECU where the cams are in their rotation and allows it to fire the spark plugs at the right time.

As for the scraper, if it broke it might cause a little damage like banging up the weights on the crankshaft or a rod cap... but what is going to break it? There is only oil in there and it's bolted down with 5 nuts at 60ft/lbs. It's not going anywhere and 1mm is plenty to account for heat expansion. Also the oil pickup is the only place an engine gets oil from the pan so it won't cause any oiling problems.

Yeah, I might go do another base run since the guy had my A/C on at the last one.

Mister2.2 · 08-30-2006, 04:34 AM

Do you want the ITBs or would they be useless for you?

PHOENIX · 08-30-2006, 06:10 AM

out of curiosity sakes, how much are you selling those?

At this point I am not interested because I want to switch back and forth between NA and turbo. Maybe someday. Dave can use them on his BEAMS!

Dirt cheap, they were given to me for free so I am just looking for a few bucks for shipping. I am mostly interested in seeing them go to an all out 5SFE build up, though.

PHOENIX · 08-30-2006, 07:10 PM

*cough* all out beams setup *cough*

what size TB's are they?

Mister2.2 · 08-30-2006, 07:19 PM

I'm not sure honestly and I don't have them here to measure. They are from a GSXr 600 maybe? They are about the perfect size for a built 5S, spacing is perfect but I don't know how well they would work for the BEAMS. Also it's definitely not a bolt on mod, you would have to mount the TPS and vac lines.

PHOENIX · 08-30-2006, 07:20 PM

yeah, those are way to small for a beams ITB setup. cool idea though!

Mister2.2 · 08-30-2006, 07:24 PM

Why do you think they are too small for BEAMS? The 5S is 2.2L and I think they are suited well for it... What size do you think you would need?

AndrewMcG · 08-30-2006, 07:34 PM

Lets see, those ITB's were designed for 600cc and now you are saying they will work well for a motor that is 2200cc? Thats almost 4 times as large. They cannot be large enough for an "all out build" for a 2200cc motor when they were designed for a 600cc motor.

Mister2.2 · 08-30-2006, 07:41 PM

I have no clue what size they were from honestly. But you aren't revving nearly as high, either. The total area from those ITBs is much higher AFAIK than the stock TB.
