Any idea what the Teg does in the 1/4 mile? There are a few of those around here.

Have no idea, never even spoke to the guy, right after I ran the civic the Teg was waiting for me.

Damn your so lucky!! Where are you located? Around here there is so many modified cars, but right now we are all hiding from the snow!!!

So to get this straight.
You have a 3.4 block under a 3.5 head?

Mixing and matching doesn't mess with compression ratios
or anything like that does it?

Congrats btw. I'm boosting an m30 too :)

The b35 combustion chambers are slightly larger than the b35 head. So when paired to a b34 bottom end, the CR drops slightly below 8:1.

Here is my M30 compression ratio calculator. It should help you out.

great results mate.looks like your timing gear's holding together :lol:

One Q, with such a light flywheel,
whats the torque like off the line?
or is it a rev happy donk with all go at the top end.

reason i'm asking, just about to fit a 17.7lb/8kg flywheel.
matched to a M5 box and a 3.25 diff.
the M5 has a rather tall 1st gear
and the big q will be if it's going to be a pig to keep from stalling

cheers marty

B35 block with M90 head which is still a B34 head with a hotter cam.

Torque is still there and screams upto 7000rpm easily.

Here's more vids same races in the other cars.

Turbo manifold help!!!! :(

Post by Handale30 »

hi, I have my M30 ready and all the turbo parts ready for 8 months now but cant get a hold of a manifold that fits the e30 m30 and is top mounted and can have enough space to fit the afm and filter in front! :( do you guys (Good & Tight) know where i can buy one ore do you have one I can buy?? Here in Honduras there are not many shops who can make them! Thanks alot
=)

These EVO's are running race gas and 35R turbos putting down between 450 and 500whp.

40 roll EVO 35R w/E85 he steps on the brakes when we a reeling hard.

A lil update.
The cooling system was pressurizing after WOT 4th and fifth gear runs at 18psi so I pulled the head yesterday. It seams that whoever resurfaced it before left the surface too rough in some spots which caused it to leak under high load. I'm sure all the times it spiked to 22psi didn't help it either.
The stock gasket deff holds a good amount of pressure with the ARP's.

So my thoughts are to swap on a B35 head, MLS, with a Shrick 284/280 cam double springs, titanium keepers and see how much it can take.
Ordered a 4bar map sensor for the MS the other day.

Also cc'd the B35 head and it was 65cc compared to M90 which was 62cc. So compression will drop some which will be good for more boost.
The bottom end must have been rebuilt before, the pistons are stamped 91.97.
That's it for now





:D

91.97 would be the piston size. 92mm bore.

Probably the stock piss stones.

Do you already have the Schrick cam? I'm only asking because I'm interested in Paul Burke's turbo cam. Any thoughts on that?


Also, what makes you say the stock h.g. holds plenty of pressure, didn't yours just blow out? I'm using a B35 head, stock h.g. and studs but only running 10 psi now. More boost is coming and my thoughts are when the h.g. finally does go, I'll be trying another cam besides the B35.

Yes I have the cam but just want to try it on the stock bottom end to see were it makes the power and how much. I'm interested in one of Paul's cam also, probably will try one on the built bottom end.
The stock HG was fine when it was at 15psi and constantly beating on it but when I got the boost controller and it started spiking to 22psi and running 18psi it started to leak. Plus the timing was a bit aggressive along with brake boosting it really was the problem.

This is all a learning process for me :D

Change of plans, I ported the M90 head to match the B35 manifold.

Image

Keep in mind this is just a test engine and was free so I consider this it's last hooray.

I felt the HX40 was at it's limit at 20psi and was too small and was creating back pressure plus boost came on to fast making the car hard to drive with traction issues.
So I have this Garrett laying around I wanted to try, yeah it's huge but what the heck, there is only one way to find out how it will spool.

Image
Image

It's a T6 flange but I redrilled it to bolt onto the T4 :banana:
Specc
Compressor Inducer- 2.670"~68mm
Compressor Exducer- 3.700"~ 94mm
Exhaust Inducer- 3.500"~89mm
Exhaust Exducer- 3.025"~76mm
The turbine a/r is huge 1.54 :shock:

Image

Just got the map daddy 4 bar map sensor for the MS. Hopefully be running within a month, I need my damn boost fix :lol:

That thing is massive! I can only imagine what kind of videos are to come. Good to hear the stock HG lasted as long as it did. I can't imagine you were very nice to it :lol:

Nice toes :laugh:

Just when i thought the HX-40 was huge that makes it look like a t3/t4!

1.54a/r :shock: I wonder how thats gonna spool...I say you try a divided entry manifold to help spool-up.

Get that thing back on the road and blow up the b34....If you can :D

G'luck!

I'd say you should retard the ignition timing around the torque peak 3500-4500 rpm and stay with what you got above that, maybe even increase it at 6000+ rpm.

The Garrett turbo is probably equal size to a Holset HX55 and it will help you from blowing up the motor in a way because your powerband will be 4000 rpm and up now, you'll spend less time at the torque peak.

I actually had pulled the timing back were you mentioned but it was too late the head had already lifted :lol:

Once back together it will see some dyno tuning for sure.

Lil update.
Went ahead and changed the valve seals on the M90 head, added the dual springs and Schrick.

Some porting to match the B35 intake manifold and some porting on the exhaust side.

Waiting for the MLS to arrive to put it back together. :D

I doubt you'll be making much boost in the 3500-4000 range. It should be ridiculous when it does spool up though.
