I would remove the oil squirter's anyways, thats what I have always done for other drag race applications. I will use an n/a block, as srt4's are rare where I am. thanks for the bedplate advice. Looking to do a stock srt4 piston and rod combo to start with then go from there. as for the trigger wheel, I already have a AEM series2 and optical crank/cam sensors. I would re-use that system. thanks for the crank trigger heads up.The 2003+ FWD blocks are all the same casting as is the crank. The N/A oil pump is more coveted by some and superseded to the turbo pump anyway. Turbo blocks are drilled for the oil drain tube and piston oil squirter's. Those are easy, and the "new fad" is to remove the piston oil squirter's anyway(less chance of failure and less oil gets past the rings to cause det). The bedplate is what can crack at high HP, so it is milled flat and billet "straps" are used to bolt across the mains. DCR has come out with straps that dont require machining the bedplate and claim to still handle high HP. 500whp is about the limit for stock SRT pistons, rods and when the mains start to squirm, if the tuning is good.
Upgrading the trigger wheel may be wise also, as some loosen or shatter, taking out an expensive build.
There are quite a few high HP builds on the different Neon and SRT forums that you may gleam some good info from, but the basic answer is that you can start with a N/A 2.4L engine if building for high HP.
I use rockett 118 or vp c16, sometimes q16, but i don't like the cost of q. or c. for that matter. rockett is good stuff and cheaper but not by much and shipping over an ocean kills especially with hazmat fees.What kind of fuel are you going to be running. That *might* have an impact on how well the bottom end deals with the intended power goal. As stated the bedplate it the part that shows its weakness first. With correct and good bracing 1000hp can be put through it, BUT, I'd be willing to bet on a filled block.
If you are talking about the 2.4 out of the SRT-4 Neon, then that is a cast iron block. No sleeves to worry about! I don't know of any issues with the bores on them, however that's not to say it can't happen. We've had a few instances of people with 2.2/2.4's crack them at the top, but that's only been a few cases and above 500whp. Thus far posting the block in that area has solved the issue without loosing drivabilility from what I've read here.
Start a new thread- you'll get more responses that way instead of piggybacking another thread.I have a 2002 dodge neon automatic and I am looking for some information on what it would cost to transform it into a srt motor? Im new to up grading motors/ what would I need to do that I know a Turbo kit but what else.
