Turbo conversion for base donor

[Pizzaman]

I was originally wanting to just start off with a SS donor build but I’m having a very difficult Time finding any ss donors even looking quite a ways outta state, so I’m curious if I got the base model and did a turbo kit, id be planning to have over 400hp but I’m not sure how well the 2.4L NA engine would hold to that. Anyone have any suggestions?

To answer partially answer your question, the 2.4 is a pretty stout engine. Turbocharged it can put out 300+ HP. ZZP and RPM Performance have kits for the LE5.

 

[Pizzaman]

Yea that’s what I’m looking at right now

The 2.2 has a good history holding around 250 WHP supercharged or turbocharged. Above that, stronger internals are necessary.

I was originally looking for a 2.4 donor, but they seem more rare than either other SS.

Good to know thanks! Also that’s really weird that the 2.4 were hard to find that seems to be just about the only thing I can find

Justin Reed is running a 2.4L block, with a girdle, and forged LSJ internals, on his new engine. The LSJ crank is short stroking the engine, so now he gets 2.1L displacement, but higher RPM. His old engine made 585HP to the wheels, and his new engine is aiming bigger, so basically, that block has potential if you want to spend money on it.

Ok I gotcha yea I was curious what he was running now, I know for sure I’ll do injectors and cams but I may do the pistons and rods while I’m at it

A lot depends on how much money you want to spend on it and how reliable you want it to be and how often you want to dump money in it. Justin probably expects to go through a motor every year or two even when building it the best possible.

The new one put down low 600s. His car is pushing some decent power

Yeaaa just decent nothing more… not like it’s almost 1hp for every 2 pounds the car weighs pffff

Any of the blocks are generally good for 400, but the LNF (SS turbo 2.0) and later blocks are a bit stronger than anything older than that. LNF (SS turbo 2.0), LSJ (SS supercharged 2.0), and early LE5 (SS naturally aspirated 2.4) are the only stock bottom ends that might hold 400whp. If you're putting rods and pistons in the motor, it doesn't matter too much where you're starting, except the early 2.2 motors have an ECU that can't be tuned with HP Tuners.

I'm going to see how my stock-LDK (no balance shafts) does on its second summer at 440hp this year I know one day im going to leave oil on the gound LOL.

Nuker-

Part of me wants to try the same use to failure thing when boosting my L61, but I'm also scared and feel a need to add a scatter shield or something before I do lol
