This thing is going to be amazing. Make sure to get some videos up of it running when you get done!

Something is very wrong with this picture!! safety patrol safety patrol!! What the hell are ya thinking wearing stockings under your sandals!! work like a real man and take those off!! dammmmmmmm!!

just kiding, very trick project, this is going to be sweet... the only reason you aint getting 500 whp is cose its going to spin on the dyno!! will this turbo flow enough cfms to get 500whp with only 22-23 psi??

also, are you building the block?? pistons?? rods?? what are you planing on using??

[ultra_runner]

You got a point about the sandals thing and the though crossed my mind a couple of times. I used to live in Japan and so I get used to these things in the garage.

Anyway - That turbo will flow upwards of 600HP. However, after going over quite a few items with the folks at ATP Turbo, we're opting for a slightly modified GT35R that will flow 500++. We will probably mate that with a 46mm Tial External Wastegate along with a Tial 50mm BOV and SS RIP piping (already procured). However, looks like the bottleneck will be that S60R exhaust manifold. Even ported out, it may restrict the flow at anything over 500HP. So - we're shopping to possibly do a custom manifold local, or shell out the big $$$ for a Pipearts SS Mod 1 manifold. ATSpeed is also working on a SS manifold, not yet ready, but reportedly will go for $1500.

So - going with SPM (Sweden) rods (reportedly good for about 1000HP), Venolia custom forged Pistons .024 over (both already procured), probably some SPM valve springs. Custom Intercooler from ATP? Few other items around the engine. Everything cryo and dry film treated where applicable. Everything will flow into a (slightly modified) Jesse 3" downpipe - 3" exhaust all the way back and into an obnoxius looking HKS 120mm SS muffler (already procured).

Any other questions - shoot away!

I'm thinking (there we go again) of getting a custom aluminum flywheel made unless anyone knows one on the market. Everything has to be balanced - needless to say. So the engine alone should ( ) be silky smooth. That will help with gettin' the RPMs up there to spool, etc.

www.isa-racing.de used to have aluminum ones (7 kgs if If I recall Correctly) they stopped them in 2006 as they did the AP-racing kit. I dropped them a note, will let you know when i get an answer.

isa-racing also carry (carried) drexler LSD's for our car. Custom from 30 to 100% lock. they also engineer to order.

I'm not shure how good it would be for you to install a lightweight flywheel on your car... this is how i see it:

First off all the changing to a lightweight flywheel will not help in smoothness compared to the stocker as long as you get it balanced, if it isen't already.

Second off all, a lightwheight flywheel makes the car rev happy in the sens it's easyer to accelerate the engine under 0 load, but it's also harder to keep it up in the revs if you let off the gas i.e when shifting (not considering you fullthrotle shift alot) because of basic inertia principals.

Now my fear is that while shifting, in an effort not to let the revs go down to much, past the friction point of the upcoming gear, you'd have to shift like a maniac, and that would be really hard an OEM tranny that is already getting a severe beating from a 500+ WHP motor...

I say this because one of my friends had put a lightweight flywheel on an H22 swaped prelude, and when he shifted in a race situation, if he wasen't quick enough, trying to save his tranny from to much abuse, he would get out of the VTEC... loll VTEC sucks!loll

Are you really serious that all of this forged and dry film pistons and all of this

are going to remain on the M66 without upgrade to it

What is the WHP goal just tell me that because it looks as though the transmission life can

only be realistic at around 375 WHP

I wish you really well and it great so I am not trying to create bad luck but only need to know

what WHP you want

Bah...the swedes are running up to like 900 HP through their 850 engines and their M56 boxes...they dont detonate that easily. Unless M66 is significantly weaker it can take plenty of power.

I always have thought you are one of the best posters here but I do understand there is a difference between swedish drag racing versus reliable transmission life.

At more than around 450 bhp or 375 whp I do not think the M66 will be reliable. If the transaxle is babied or not used in first and second so much it would be ok at 450 bhp but would not last so much if used at 0-60 mph races

I think maybe 390 whp but over 500 bhp is getting really close to the limit so 500++ is crazy in my opinion

[ultra_runner]

Guys - Helmut is actually pretty accurate with his numbers below. From another (very credible) source, the stock gearbox is good for about 400HP. I am also told that even the Volvo race shops in Sweden that have custom internals, it would still be only limited to about 450HP. I assume wtih the M56 being around longer than the M66, there would be more solutions in the market for beefing up that gearbox. I am looking M66 solutions right now, but difficult to find the sources. If anyone can assist here - would greatly be appreciated.

Another approach would be to NOT use the M66 base and go with an Xtrac 393 gearbox. This of course - would blow the doors off any budget and render the car somewhat less than streetable. The ATSpeed GT cars use the Xtrac 393 and they are good for about 550HP . The GT cars are running the NEW Cosworth engines at 600HP and the gearboxes have been breaking regularly.

Suggestions? Either build up a beefy M56/M66 solution or go with a Touring gearbox from Xtrac.

Well there's 500-700 HP cars there that are driven daily. I dont know the exact differences between the boxes however...though I imagine the box being used for FWD only could simplify things - if only a little.

[550]

Yeah jcv is right... there are 700 + hp cars in sweden running an m56.

hi im new to all this.i live in scotland in the uk and there aint alot on offer for the volvo t5.mines is a 1996 850 model.full 3" straight through exhaust,chipped running 14psi.bilstein suspension and uprated brakes rotors with ceramic pads.im intrested on your views as to further tuning this car?i own a 420bhp escort cosworth but think im going to sell this and keep my t5.id like a power output of between 400+bhp and 500bhp.what wo0rk goes in to this engine to make said power?and how reliable will it be?any info gratfully recieved!!!ie recomended turbo,cams,injectors etc.regards barry

which car is the M66 off of? i.e. the 5-speed in my C70 right now, is that anything anywhere close to this beast of a thing... noobish question. I know.

not really that noobish of a question...m66 is off of the the newest R's (s60/v70)
