325 i stroker kit

[jameschill]

hey my name is james just wanted to know if anyone would know where abouts in australia i could find a stroker kit for my e30 88 model i want to stroke it to a 3 litre or even 3.5 litre please let me know thanks

you can use the S52 crank and have it machined to make a 3.2 + larger bore so maybe larger, i just cant understand why you would want to do that on a single cam 12v engine...just swap in a S50 or S50 or at least an M30 (which is already a 3.5L single cam 12v)

check out Ireland Engineering | Racing and Performance Parts for BMW E30 and 2002 and other Cars they have stroker kits

maybe he wants to be special lol and unique I wanted to do a s50 swap. but my friend wanted to drop in my dad's 454 ci chevy big block.<do this if you want a drag type car. s50 if you really have to go around a corner with traction.

a big block is not going to fit without a lot of modification, and then the chassis is way too weak for that...you would have to cage the entire car and reinforce the entire chassis...

S50 swap barely weighs more than stock M20 and makes 240ish hp

a full built 3.0 M20 stroker with a gnarly cam will only make 220ish hp, and you still have a timing BELT and mechanical lifters to adjust where as the S50 has a timing CHAIN and coil packs and hydraulic lifters...

but it would spin the hell out of the tires and be really fast......well in a straight line...... i think the car would be fun but loose its handling
i want one with a big block and one with a S50 and paint them the same except the pin stripes one green with black base and one blue with a black base green big block blue S50.

a proper 2.7 M20 will make 220hp and a 3L M20 will make atleast 240hp if done right but the advnatage of the 24V S5x is that they have the lowend that you'll sacrifice in getting 240hp from a m20 plus they (s5x) can be modded to well over 240hp.

Being a fellow sydney sider there are no S52 or S50 US becasue we have the Euro s50b32 and s50b30 so these will cost alot to swap into a E30 but so will the build costs of a proprely done 3L stroker M20.....if you want pure power and torque FI is the way to go.

Best BFYB is save up for a 1996+ E36 M3 Euro which can be had for around $30k AUD has the power and the poise to go with it.

It all depends on your budget!

the only reason i wanted 2 stroke it because i'm a p plater and cannot drive any supercharged v8 or turbo or any m series cars i value my licence lol i wanted to make the most of my engine and do the most modifications out there swo make my e30 go like an m3 i done a 15.1 at the creek i wanna be in the low 14's high 13's as a naturally asperated car i know it's a big ask but thats my aim

Hey guys. Sorry to threadjack.

I am really looking at getting a 320i. They also have the m20 in, right? Would I be able to use a s50 or s52 crank in it? Would I have to find a specific crank from them or what? Basically, I have no idea what all it entails, would anyone mind enlightening me? Would I need a fuel management system?

Thanks
Mike

thats a very good time for a mostly stock vert, what trap do you run?..........

Cheapest way to lower the time is weight reduction as well built stroker or swap is going to cost $$$$. You could do a budget 2.7 or 2.8L and if your pretty handy the costs would be reasonable although i doubt you'd knock a whole second off the time.......

S52 cranks will fit without too much trouble but you may need to check clearancing with the rods to the block and intermediate shaft and you need to get a sleeve made to fit the crank for the oil seal etc etc but it does work.
IIRC the 320i has smaller 80mm bore so the issue will be what pistons to use as the S52 and S50 cranks require custom pistons. The UK guys like using 320i blocks and boring them to 84mm for their strokers so that may be an option or get another cheap block its best to use a bigger bore for more displacament. What year 320i is it? The later ones use the almost the exact same engine managemnt as the 325i which with injector changes and remap is capable of doing the job reasonably well.

[I34z1k]

Well I am still looking around for now. I want a 2-door. Now I know what to look for at least.

So if I get the 320i, I can have it out bored and chuck the s52 crank in (from any specific model?) and have a new sleeve made, get some diff pistons and it should work?

so pretty much wat ur saying is that theres no point of doing it because i won't get there with a naturally aspirated car

no, just saying you won't get there cheaply on a NA car

[I34z1k]

I for one don't want to go turbo. And supercharging is too pricey for me. So yea. A 3.2 with ITBs will do well here
