hi there,

i have a question on this particular e30 engine, i would like to know is it advisable to add HP :
a) change the throttle body to 2.5?
b) or just rebore the original throttle body to 2.5?
c) Upgrade my current extractor to a custom one?

For question (c) i heard that a new custom extractor will be more hotter than the stock ones yet better flow ofcourse but it will melt seals around the engine. please advice me sifus. thanks!

Okey, M20 B20 Motronic or L-Jet?

If you plan to keep your B20 engine, 2.5 air intake, 2.5 throttle body and 2.5 fuel injectors with performance fuel regulator will do it. BUT you still cannot fight B25. You also can R&D your rear diff.

Cheerio

p/s Oh yes, like last TT chriseunos suggested to remove all carpets, door trimmings and even pass motion before drive hehehehehehe (joking only ahh)

okay you forgot to mention yours motronic or L jet. Kalu L Jet, kena mod you punya throttle body. kalau tak pun get the whole assembly.

cost
M20B25 Intake manifold with throttle body
RM300 to RM450 depending half cut shop pricing.

M50 (6 biji) Injectors will cost you around RM200 to RM250
also depending half cut shop. Why? kadang2 halfcut shop taruk harga
tinggi. if you lucky can get RM150

Please diagnose your injector first kot kot takut rosak.
Cost diagnose/cleaning RM25 to RM30 satu biji x 6 biji.

Workmanship tak tau lorrr... Good luck
