M90 Pump gas Buildup!

TDCRacing · 01-09-2009

This thread is for whoever cares to follow along. I will be showing step by step of what is being done and will be posting lot's of pics. I will be doing things like blower porting,Cam install,Roller rocker install ect ect. So hopefully it will contain lot's of good info on a wide array of things.That's the point of the thread in the first place..

With the turbo build down the drain for personal reasons, I've decided to go all out with the m90 buildup. This will make it a lot easier on me because it will be almost 3000 dollars cheaper. It will be done right. So if someone see's me doing something wrong, Don't be shy to correct me,I only want to do this once.

I plan on setting the record whp for the IS3 Intense camshaft. The current record is 399 WHP set by Ted Quartana.He was using a gen 5 and Is3 heads.

The build will include the following new stuff,

L26 6000 mile engine
IS4 camshaft (.600/.601 with 1.6's)
Ported and polished heads w/ 1.9 1.57 valves
Gen 5 (Ported inlt & outlet w/sealed slits)
Yella Terra 1.6 roller rockers
65# mototron injectors
Comp Cams OE-R lifters
Mezere electric water pump
130# valve springs
ARP head studs
Retainers & locks

I'll update with the parts I get in as time goes.I plan on posting pics of everything that i'm doing along the way.

This is just some quick shots of the stock gen 5 before the porting.

These are some pics of the ported sc inlet and outlet. Probably will be painting it instead of powdercoating it also.

Just bought the Gen 5. Picked it up for 350.00 shipped to my door with 45,000 miles on it. Should be here in about a week. Plan on porting it then it's off to get powdercoated. After that it's getting a fresh rebuild.Possibly with ceramic bearings.

I plan on following, I think it will be interesting to see if you can break the record. I'm rooting for ya

TDCRacing · 01-09-2009

Yeah it's more of a personal goal really, But that's just my excuse if I don't make it LOL.

**1998xGTP** · 01-09-2009

Haha that is what I was going to say. Going to be a driver or track car only?

TDCRacing · 01-09-2009

This is my only daily driver. Looking to run Low 11's for sure. After I break the record (fingers crossed) I plan to put the bottle on to run Real low 11's and maybe break 10's.

**1998xGTP** · 01-09-2009

Wow I wish I had the guts to do this to my DD lol. 2x fingers crossed I want to see a member break it :P

Yup ceramic m90 bearings. Not sure if I want to shell out 200 bucks though.

haha. he always seems to pull magic tricks out his ass dont he??

**SyntheticShield** · 01-10-2009

Well I'll offer this little tid bit for you. One of the advantages of using the ceramic bearings is that they reduce the parasitic losses from turning the blower. However, if you bought some high quality high speed regular bearings you could have them cryo treated.

I dont know if you have a place around where you are that provides this service, but cryo treating such parts makes them a bit tougher, it reduces friction which would have the same parasitic loss reduction effect. So it could be worth looking into.

TDCRacing · 01-10-2009

How much do you think this would cost?

TDCRacing · 01-10-2009

Just to let everyone know the blower is comming on wednesday

**chrisb** · 01-10-2009

interesting cryo treating the bearings? i dont know how much hp the ceramic bearings would free up maybe 5 or 10. i know how ya feel 200 bucks is a lot for bearings been lookin into it myself.

your porting the blower right?

I wouldn't think that much but I could be wrong. Someone dyno'ed before and after a gen 5 install and after he picked up around 32 horsepower with that being the only thing he changed. So that's the main reason i'm going with the gen 5. Even if I only see 10HP It will still be worth it to me!

If your talking about shauns build, he also went from a ported TB to a N* and LQ4 maf when he switched blowers IIRC. So the gains from swapping SC is not as large with out a TB swap. At his power level his TB was holding him back some. He also had a home ported gen 3 before so depending on how his porting was the power gains from the swap are not as cut and dry as you are saying. The car was also retuned before going back to the dyno so that can play a large factor as well. Not saying the Gen5 isnt worth it but those gains are not always that common from just swaping on the new blower and nothing else.

Also is there a reason you are going with the IS4 cam? A custom cam tailored to your build would be better suggestion. That or an XPZ cam, somthing that was ment to work well with a small blower like the M-90.

TDCRacing · 01-10-2009

Yeah. Ported inlet from 75mm to 78mm to match my zzp TB. No majior outlet work but I am going to make it the best I can.

TDCRacing · 01-14-2009

Update-

Got the Gen 5 the other day. Cleaned it up and just ported it today. Did not do much at all to the outlet but did port the inlet to match the 78mm TB that I have. Will be posting up some pics soon.
