1.9 to 2.4 Conversion Project Started

opelwasp · 02-24-2005

Well, i am finally going to get to bild my 2.4L per Bob Legere's specs of course. Thank you, Bob. My plans are to bore and stroke it to 2.4L with low comp pistons not the flat tops. I am putting on a well ported head with 2.0L intake and exhaust valves. Combo cam from OGTS with hyd lifters. 2.0L fuel injection using the Megasquirt. Mechanical advance distributer. Parts inside will be cleaned up, polished, shot peened, balanced, and deburred. I decided on the low comp pistons for a posible mod later on down the road.

I will be posting pics and progress as it goes along. I will also have a running total of parts and engine work as it gets done. Right now the pistons are getting milled, and the rods shot peened, small ends bored out, and big ends reconditioned.

Stay Tuned

opelwasp · 03-12-2005

opelwasp · 03-12-2005

heres some head porting pictures from the combustion chamber side.

opelwasp · 03-12-2005

here's looking down the intake prts

opelwasp · 04-05-2005

just got my parts in from OGTS! 2.0L exhaust manifold with pipes, 2.0L EFI system, finished cam bearings, and the 268 hyd cam (combo). thanks to the guys at OGTS for sending the Y pipe for the exhaust instead of just a flange. now is time for clean up. need to look into the MegaSquirt too now.

opelwasp, Are you doing the porting or is the machine shop doing it? It looks very good so far too. I'll be very interested in your updates as I have a High Comp engine I'd like to rebuild this summer. Keep us posted. Jarrell

opelwasp · 04-06-2005

all porting work has been done by myself. it is not as good as id like but i am inexpierenced and too chicken to take it any further. i just hope it wasnt a waste of my time and no gain ia accomplished.

opelwasp · 04-12-2005

Got the pistons back from the machine shop. Cost me about $130 to get them modified. They look great. I went low compression so i could save a little gas money for now, and still be able to supercharge it later.

Matt M240Z · 04-12-2005

how much is a stroker 2.4 crank and the shorter rods?

BetaCarotene · 04-12-2005

doesnt really answer your question but shows you what he will be following

opelwasp · 04-12-2005

that is correct, i will be stroking a 1.9 crank and using the stock rods.

spdkilz02 · 08-12-2005

i was wondering if you ever got this project done or not? and what were the results if u did finally complete the conversion?

opelwasp · 08-12-2005

well... it is on hold right now. I am waiting for 550 buck to be feed up so I can get the crank done. Right now all my time and especially money is tied up in the police academy. I graduate in June 06, so as soon as I land a cop job I'll have lots more time and money.

spdkilz02 · 08-13-2005

what all do u have done to it already?

asdasc · 12-31-2005

Umm, go to Post # 14 in this thread, right click to "Save As" on the link, and there you have it.

asdasc · 01-01-2006

Yep, I have saved it already. I was thinking we could put it in the downloads section for others that come later...

opelwasp · 04-10-2006

well the crank went out to detroit last week. took the block into the shop to get bored and head to get thermal cleaned. I also took the flywheel to get setup for the S-10 clutch and pressure plate.

and i got pics.

cost total of $151 to get the flywheel surfaced, drilled, tapped, and balanced. $107 for the clutch kit new.

now its time to just hurry up and wait

asdasc · 04-10-2006

Awesome clutch photos! By the way, I just bought the s10 clutch kit for mine and it was $79. I was pretty happy with that. I still need to confirm it fits my transmission spline, but no one seems to me having an issue with that.

By the way, where in Detroit did you send your crank? What was thier price?

opelwasp · 04-10-2006

i sent it to Crankshaft Craftsmen $530 plus shipping to get it back to me another $30.

$79 was for the reman here and $99 for a brand new clutch kit.
