my m52 build

[ziptied]

hi all. i am in the middle of boosting my m52.

i am building the motor with
wiseco 8.5:1 pistons
going 20 over on bores to make sure they are round which i believe makes it a 3.0?
molnar rods
bearings
caps
hardware
and seals

i have a few questions considering i have never even re built a motor in my life. sure you guys are probably laughing. hehe

1. are oem bearings okay for a forced induction motor or should i go more expensive with vac or something?

2. i have been doing research and a lot of people are saying that the f1 stage 4 clutch kit off of ebay is actually pretty good? anybody here ever used or have any experience with this clutch? Driveability? gear chatter with lighter flywheel?

3. i dont want to run the charge pipe underneath the car. so i have seen some people rout it basically right underneath the manifold alongside the block, is this an acceptable way or does it get too hot?

3. any other questions or comments you guys have feel free. im gonna figure out how to put some pics up. my computer skills are limited. hah

and i am building on a budget but i want to do it right.

Looks like your on the right track, the OEM bearings will work just fine.

What is your horsepower level ? Manifold, Turbo Sizing, Inter-cooler, etc.

i need info not smilies!!! lol

[ICS Performance]

i need info not smilies!!! lol

How much horsepower are you looking for ? Pump gas, Daily driver ?

Need more specific's

[ziptied]

well i am having some serious thoughts about going top mount now i feel it is much more practicall and oil draining is just better, and to be honest i have never dealt with a turbo besides a little with my diesel cummins. so im rather novice. hahaha

horsepower goals are 400 to 550
turbo is a turbonetics t3/t4
i will be ordering a 30x12x2.5 intercooler, seems like a good size to fit behind the bumper.
i deleted all the ac components
technica motorsports tune
and im trying to deside on wastegate according to what manifold i get.
and pump gas for now


side note: i originally purchased a little "kit" from some guy off of craigslist for 500 bucks........... lesson was thoroughly learned from that one. stupid i know. but i need to finish strong and do it right, for my own good.

1. OEM bearings will do just fine

2. The F1 clutch will hold some power BUT if you are speaking of the full stage 4 kit w/ single mass flywheel I would suggest stepping down to the stage 3 . The stage 4 kit contains a unsprung disc, this will work well w/ your factory DMF. The stage 3 full kit has single mass flywheel and sprung disc.
*running a unsprung disc and single mass flywheel will result in a noise and vibration*

3. Running the charge piping along the block will do just fine. A great setup would be a SPA manifold T3 and a GT35R turbo. Should give you a reliable 500 rwhp and plenty of clearance. I wrapped my charge pipe with header wrap and haven't had a problem whatsoever.

Only advise I have is if your on a budget (which most of us are) build yourself a nice reliable setup. Once you start chasing the BIG numbers to keep up w/ the neighbors its going to get costly quick and will consume you.
450-500 rwhp is an awesome setup for the street and will put a HUGE SMILEY on your face.

EDIT. Go atleast 3 inch core size on intercooler; )
GREAT CHOICE ON THE TECHNICA TUNE

Budget build.

SPA T3 Manifold (Port the Waste Gate Port to avoid boost creep)
SPA 38 MM Waste Gate or a CX Racing unit.
Precision 6262 non ball bearing (or a Holset HX35 off a ******** Diesel)
CX Racing Inter-cooler, get yourself a 3.0 core
3.0 Turbo Back will work
2.5 Charge Pipe
3.0 Cold Side Charge Pipe
Walbro 255 Kit (Fuel Pump)
Rally Road Engine Bracket
F1 Clutch, I have never used but have heard will hold the power

What else ?

I offered a welcome wave to a familiar face...
not just ANY old smilie, Captain.



You've only asked THREE (3) questions (#1, 2 & 3) here in this thread
and those topics have been covered here in FORCED INDUCTION subsection for years. A few searches will answer them quickly.


Welcome to the forum again...
and once you've finalized the simple hardware/kit decisions you've already talked about
(you obviously have more than innocent, minimal knowledge of BMW turbo set-ups )
start a build thread and so we can enjoy the progress and photos.

[ziptied]

okay this feedback is priceless for me!! rather excited.

Butter stotch: im not too worried about making this a comfortable ride its not my daily driver, the only thing i would be worried about is the stage 3 being weak for my needs? that would suck lol and when you routed your charge pipe did you weld a ninety on your compressor housing then weld the piping on? im just worried about any silicone joiners melting and causing havok.

i have a tune from technica and along with it came the pump so i think that is taken care of.

Both: once again thanks so much for the feedback.
and are you guys agianst the t3/t4?

haha i see i see. i figured i would start a new thread to see if i could get some feedback and some interest! and as soon as bimmer forums allows me i will be up loading photos and videos of my progress and regress lol

My GT35r has a 90 welded on. As far as the silicone joint melting, I did experience this. What I did was wrap the silicone coupler in header wrap. Since then no problems at all.

As far as the clutch goes, I've given my $.02 . A solid hub disc with a single mass flywheel will be harsh.

Looking forward to your build

okay cool! im sure if i ceramic coat the manifold as well that would help a bit too.

and as soon as i figure out how to upload some photos i wont hesitate to do so.

My silicone 90* melted too. super aggravating. So I also have a 90* aluminum elbow welded on too. The 90's can be found on eBay for 20 bucks and i cost me 60 to have it welded. Cheap insurance.

Aren't you looking to step up your game ? Sell him the manifold, charge pipe and your GT35R and go to the SPA T4 and 4094R !

I've been thinking about it, but I feel a 4094 on a 2.8 may be a little too much and lag might be an issue.

[pbonsalb]

are you guys agianst the t3/t4?

What T3/T4 is it? The T4 compressor could be well matched to the T3 turbine or it might not be so well matched.

Yes it will be, I forgot your on a 2.8 !

[BadBoostedBmwM3]

I've been thinking about it, but I feel a 4094 on a 2.8 may be a little too much and lag might be an issue.

Probably so! But, a gt4088r with batmowheel and some s52 cams would be very nice!
Hell, s52 cams would just be a nice addition.

haha you totally should sell it to me!!
for some reason im having an issue finding a t3 spa manifold

[Butters Stoch]

I have a set of S50 cams I picked up from a brother on the forums.
Ill install soon.

I have been toying around with the idea of twin T60-1's . That would be a cool little project that could fit the budget.

i got those too!! going in when i put the head back together.
thinking of that does anybody know if i need to get m3 valve springs? due to the squanch? or is it not that durastic of a change?

What T3/T4 is it? The T4 compressor could be well matched to the T3 turbine or it might not be so well matched.

its the turbonetics t3/t4. i know it sounds crazy but im not sure what the ar is or anything?

My silicone 90* melted too. super aggravating. So I also have a 90* aluminum elbow welded on too. The 90's can be found on eBay for 20 bucks and i cost me 60 to have it welded. Cheap insurance.

alright that makes sense.
but what about after the welded ninety? there was a silicone couple there? or what was there? v band clamp maybe?

and i am seriously thinking of going top mount now? anybody have pros and cons with this?

i was thinking the obx top mount, reasonable priced.

i think the oil would drain better, i could rout the charge pipe easier and the turbo would be in your face, easy for maintenance.

cons would be heat in the engine bay but there are solutions for that,
......

[pbonsalb]

There are a few variations on a T3/T4. Some work better than others. You need to find out what you have.

Great!

Will s50 cams fit in m/s52 trays?

IIRC, they will. But, it won't work the other way around.

[ziptied]

can anyone give me an opinion on this? pretty please

I have the OBX top mount with a gt35r in a coupe.. I havw issues with opening the hood because of it, but when i had it in the sedan i did not have any issues at all. I did make the mistake of using the thick OBX gasket it comes with, im going to switch to a metal one and see if it helps at all. The fit is very tight though.
