[325is_MadBimmer]

Ok so i know that the 325es has more torque and less hp, but why??? arent the engines the same??? whats different o nthe "es" then the "is"??

thanks guys....

ps - sorry if i sound like a noob, but i am very knowledgable on the e36, but just starting to get into the e30 scene, and LOVIN IT... ;)

the 325es is a 2.7 liter engine. But the 325iS is a 2.5 liter with higher compression pistons, etc etc etc.

They are both M20 engines, however different blocks.

[OOMPH!]

The "is" is basically the luxory package I believe. Nice leather heated seats, pw windows, etc..... someone else might want to chime in because I'm not an expert. Yet... :twisted:

umm quite far off ;)

[325is_MadBimmer]

so which engine do you guys think is better to mod???

what kind of hp gains can i expect from these engines with boltons?

[Erick]

Optional-wise they are very much the same. I'm pretty sure the 325es was the first e30 with power everything, the LSD ( however the i has a different ratio ), basketweaves, premium sound, etc etc

thanks, Oh yeah.....I forgot about the premium sound system, basketweaves......... I know, I have a lot to learn still. I'm not denying it 8)

[325is_MadBimmer]

ok so what about a 1986 325 (no letters after it) please dont tell me it has that 127hp engine?!?!?!?!

[YAN-3]

dude actually its a 121 hp 2.7l e car

[325is_MadBimmer]

NO!!!!!!! ohh well.....how much can i pick up engines with 120k miles on them from lets say a 1986-91 325i or "is"????

... how about the sport suspension, optional LSD, and sport seats? :idea:

now Madbimmer:

Here's a synopsis. The M20 is kind of a crappy engine to mod without forced induciton. You can spend 5 grand on a stroker and entirely rebuild a motor with much larger displacement, you won't get above 225HP.

If you turbo (see what matt325is, et al) have done, you can get figures over 300HP, but you need to plan it right.

Without a doubt, get an i or an is if you can. While the eta is a strong motor, a 5200rpm redline, 121HP, and earlier bodystyle are all downsides for me. This applies to the "325" cars too. I won't get started on the "super eta" stuff. You wont find one anyway :)

If I were you, I would look for the following cars:

1988 325i
1988 325is
1989 325i
1989 325is
1990 325i
1990 325is
1991 325i
1991 325is
1991 318is

so what engine swap would you guys recomend for these cars???

M50 or S50

M50 = 92-95 3-Series motor (not 318)
S50 = 95 M3 motor

They are both M20 engines, however different blocks.

Both the blocks are the same. The head's are the diffrance. The "e"or "eta" has a longer stroke.

lol, I guess I am the only one that loves my 1986 325 (no letters after it either)
