Greek 850 T-5/hopefully Over 340hp.

[BlackT5]

For those of you who have already performed the 960 TB swap on an 870 turbo, i would really appreciate your comments about the difficulty-level of this swap, and its effects (if any),

It's not hard. I used a non-turbo 850 throttle body. It bolts right up, but you have to bore the hole out in the manifold or the the throttle plate will hit. Pulling the intake mani is pretty easy, just be sure to clean it to get all the metal shavings out. A die grinder works best for enlarging the hole.

Thanks for the pics.... what did you use to adapt to the intake hose? Do you notice any significant advantage?

Did you notice any seat-of-the-pants positive effect on throttle-response/performance as a result of this TB swap ? i've heard about the poor flow characteristics of the five-banger cylinder heads, but does anybody think (preferably from experience) that it would be worth it to have the plenum/intake-manifold extrude-honed (the extrude-hone method of porting & polishing) while it is off of the car ?

Are the NA 870 TB's the exact same diameter as the 960 TB's, or a bit smaller ? (the image that our Greek buddy has posted of the 960 TB makes that thing look huge in comparison to the puny oem turbo TB !)

Thanks.

I don't know if the throttle body made a difference, it went on the same time as my gt35r and all this other crap. I know that made a difference

I just used a 2.5" to 2.75" reducer at the tb, then on the first piece of pipe I welded a small pice of pipe and ran a hose to the IAC.

I don't have a pic of it all finished, but you can see the small pipe for the IAC in the background

/Enough jacking of this thread.

umm, i don't see any "crap" whatsoever in your image. but i'm willing to bet that your front tires feel like, "Oh CRAP !!!" every time your right foot pushes down on the gas pedal. are you able to get traction before the middle or top of third gear, or is that a tooth-fairy thing ? Looks like you need an advanced traction control system, or multiple-stage boost control; unless they are already installed and having mercy on your two front tires and supporting drivetrain components. Nice hardware, and hopefully it's managed by some just as nice software. The tire wear is a whole different story though.

How much powah is all of that pretty "crap" making ?

last dyno was only 333whp @ 17psi. I've since turned the boost up and retuned the car a bit. Using Nira i3+ ems.

Do you have some more pretty strong "crap" inside of your short-block ? (ie. rods & pistons ?)

Is traction a big problem ?

My friend, if you ever have any leftover "crap", please don't hesitate shipping it to me (i'll pay for the shipping), because that's some of the prettiest "crap" i've ever seen before. i'm gonna have to start calling the oem Volvo hardware on my wagon crap-eating maggots (ie. 15g conical out. stressed-out by the maggot Volvo (sorry excuse for a) "manifold". The Volvo engineering team put the real crap on the '95s). It's gonna get upgraded, but not too radically.

What is the general trustworthy consensus on how much power the stock internals are good for (with proper ecu tuning) before the rods reach their (sub)mediocre failure point ? It makes you wonder why Volvo didn't bother putting a real set of rods in these engines in the first place (like the bullet-proof rods the Toyota folks chose to put in the 2JZ engines, or even the rods that Ford put in the factory supercharged Cobra Mustang engines). Cheap-s_it Scandanavian bastards !!

They desperately need metallurgy lessons from the Japanese.

Stock internals tend to start going at 300whp or less.

Great work Kimon!!.

Nice to hear that you are reaching the end and

after so much work you start up your new forged engine!!.

Hey guys I made a progress yesterday..

A last photo before the car will leave the workshop.

The front seats were in place,for the need of the ride.

Me as I was trying to fix one instrument cluster.

A table full of pieces from the two units

In this photo the bottom plate is mine the top is the other that will be in my car.

A made a modification to the wiring for the seats.My car had the manual adjusted seats,and I put the electrical operated.So there were no wires for this.Because I was bored to make new wiring from the fuse box,I connected them with the heating cables,so I only have to press the front seats button for a while.

I like these direction indicators so much.

An almost complete photo.

The front section was of to place the ballasts in a better place.

These for now.........

[lookforjoe]

Lookin' Good!

It'll be nice to hear what the performance gains end up being!

OT, but thanks for the link to your build - I've been reading through the whole thing - shame it wasn't pinned minus all the comments ...

Very, very impressive!

Well here I am again guys,I made some progress with some kilometres.

Here are some parts that I received from Volvo,a new clutch for spare,a piece of the interior,an exchange steering rack and some other things,all of them cost about 2000euros.Thank God the steering rack was agift from my Dad (700 euros)

My girlfriend was all the time together.

The EGT and A/F AEM wideband are finally on,

Too many cables in there!!!

This is where I mounted the sensor

I also changed that with a new one,it was broken because of the heat of the turbo

The wire for the EGT sensor.

I've driven almost 600km with the wastegate port open,so no boost,the EGT while this driving,is about 450 celsius,and the A/F ratio is going from 14.5 to 15.2

I have some problems with water leaking from the heater hoses but I will solve it.

These for now,I found a P2 manifold for 250 euros and I am going to buy it,but haven't decide yet for the ECU.

Kimonas.

[BlackT5]

That placement of the wideband gauge is going to suck to look at when you're driving, especially when driving fast.

[Hellas850 T-5]

It is not going to be there for ever,just for now for the first kilometres,I am waiting for some months now from European Tuning a 2-gauge pillar.There will be the EGT and A/F gauge.Down there will be the boost gauge,the oil temp.gauge and probably an oil pressure gauge(I bought a water temp.gauge but I don't know where to locate the sensor!!!)
